Description

The invention relates to a motor vehicle hinge according to the preamble of the independent claim.

EP 0 816 610 B1 shows a motor vehicle hinge, which is used for the articulated connection of a motor vehicle door to a door frame. The motor vehicle hinge has a first hinge half made of steel, which is fastened to the door frame of the motor vehicle door, and which is connected via a hinge pin hingedly connected to a second hinge half, which is attachable to the door. The hinge has a locking device, which determines the two hinge halves mutually releasably in certain pivoting angles, wherein the locking device has an approximately cylindrical sleeve which is non-rotatably connected to the hinge pin. The sleeve and a brake member are inserted in cavities recessed from the solid material of the first hinge half, the brake member defining preferred opening angles of the door with recesses or grooves provided on the circumference of the sleeve. A disadvantage of the known motor vehicle hinge is the fact that in order to achieve certain pivoting angle of the motor vehicle door, the diameter of the sleeve is sized so that that portion of the first hinge half, in which the sleeve is received, has a large radius and correspondingly far from the plane, in which the hinge half is connected to the vehicle door frame, is spaced. Since the hinge half is a one-piece steel body, numerous machining operations are necessary to produce cavities such as channels and openings which allow integration of the locking means in the hinge half. Although the hinge half absorbs due to their massive design, the forces introduced by the weight of the door and loads, but this has a high weight. In the machining of the hinge half for the creation of the cavities, a large part of the material as Span and thus as Wasted material loss. When assembling the hinge there is a risk that the sleeve is incorrectly applied to the hinge pin and thereby the recesses, which define the preferred opening angle of the vehicle door, are arranged in the wrong places. Finally, the fastening means of the first hinge half are provided clearly outside a plane normal to the abutment plane through the hinge axis, so that set by the distance undesirable moments.

DE 199 53 077 A1 describes a motor vehicle hinge for connecting a motor vehicle door to a door frame, with a first and a second hinge half, which are fastened respectively to the motor vehicle door or the door frame and are hinged together via a hinge pin. A locking device, which determines the two hinge halves mutually releasably in at least certain pivot angles, comprises a non-rotatably connected to a portion of the hinge pin sleeve whose circumference is profiled so that a spring member acted upon by a brake member which cooperates with this circumference of the sleeve, different is strongly deflected and so generates a braking torque, which counteracts the opening of the door. If the sleeve is rotated by pivoting the door together with the hinge pin, this causes a rotation of the brake member about its axis. A disadvantage of the known vehicle hinge is the fact that the hinge half, in which the locking device is arranged, is formed as a one-piece solid metal part, which is heavy and in the tough material, the cavities for the arrangement of the components of the locking device must be machined. The corresponding processing operations are time-consuming and costly. Due to the large diameter of the sleeve, it is also necessary to space the hinge axis relatively far away from the contact plane of the hinge half on the door frame, and also to form the region of the hinge half, in which the sleeve is received, correspondingly large.

DE 10 2009 014 084 B4 describes a motor vehicle hinge, in which a first hinge half with a second hinge half by a Hinge pin is pivotally connected, wherein the hinge halves are each fastened to one of the vehicle door and door frame. A locking device, which is arranged in one of the two hinge halves, comprises a sleeve arranged on the hinge pin, which generates a braking force for the door with a brake member which can be fed radially to the sleeve. The sleeve is supported on the inner circumference of a cylindrical opening with a constant radius. A disadvantage of the known motor vehicle hinge is on the one hand its high weight to which the hinge half made of solid material contributes with integrated locking device, in addition complicated cavities must be introduced to accommodate the locking device. A particular disadvantage is the large diameter of the hinge half in the area of the sleeve received therein, which not only causes a large extension of the hinge half, but also a radial projection of the hinge half in the region of the sleeve, which is undesirable.

DE 10 2012 004 810 A1 shows a motor vehicle hinge for a side door, which has a first hinge half, which is attachable to a door, and a second hinge half, which is attachable to a door frame has. Both hinge halves are hingedly connected by a hinge pin. Both the first hinge half and the second hinge half each have a support structure made of a carbon fiber reinforced plastic and a plastic insert, which can be inserted or injected into the respectively associated support structure in a direction parallel to the axis of the hinge. The insert has a receptacle for a threaded bush, the support structure has an opening at the location of the receptacle for the threaded bush. If the insert is inserted into the support structure, the fixation of the insert in the support structure is effected by means of a screw which is screwed into the threaded bushing. By screwing in the screw, the first hinge part is fastened to the body at the same time. In the injection method, the inserts can be fixed by means of a projecting rib on the respective support structure. The hinge pin has a corrugation at one end, so that it into a receptacle of the first hinge half can be fixed with respect to rotational movements about its radial axis. The other end of the hinge pin is rotatably supported in the second hinge half. Here, the hinge pin stores only on the use of the second hinge half, so that the entire vertical force of the hinge pin is transmitted to the insert; Likewise, the hinge pin is only in contact with the use of the first hinge half, so that a transfer of vertical forces in the support structure takes place at best indirectly. The hinge halves of the hinge are made by first providing a carbon fiber reinforced support structure which is then provided with a plastic insert.

DE 203 20 183 U1 shows a motor vehicle hinge according to the preamble of claim 1, comprising a first hinge half and a second hinge half, one of which is fastened to a motor vehicle door and the other to the door frame. A hinge pin hingedly connects the two hinge halves, wherein a locking device removably fixes the two hinge halves in at least certain pivoting angles. The locking device has a hinge pin associated with the locking sleeve, which cooperates with a pin formed as a brake member. Here, the locking sleeve is equipped with locking grooves which define holding positions, wherein the locking grooves are introduced into the completely formed with the same radius circumference of the locking sleeve as recesses. The brake member is in this case radially biased against an outer peripheral surface of the locking sleeve.
WO 2011 057 966 A1 describes a motor vehicle hinge in which a first hinge half and a second hinge half are each hingedly connected together via a hinge pin, wherein one hinge half is provided for attachment to a door and the other hinge half for attachment to a door frame. In one hinge half a locking device is arranged, which defines the two hinge halves mutually releasably in at least certain pivot angles. For this purpose, the locking device has a connected to the hinge pin brake member which is formed against a trained on an inner periphery with locking marks Resting segment is biased.
It is the object of the invention to provide a motor vehicle hinge which is improved in dimension and weight.
This object is achieved by a motor vehicle hinge with the features of the independent claim.

According to the invention, there is provided a motor vehicle hinge, a first hinge half attachable to one of the motor vehicle door and door frame, a second hinge half securable to the other of the motor vehicle door and door frame, a hinge pin hingedly connecting the two hinge halves, and an inboard hinge one of the two hinge halves arranged locking device, which determines the two hinge halves mutually releasably in at least certain pivoting angles, wherein the locking device comprises a hinge pin associated with the locking sleeve and cooperating with the locking brake member, wherein the locking device associated with the hinge pin locking sleeve with a radially projecting locking segment and a cooperating with a peripheral surface of the locking segment brake member, wherein the brake member is preferably radially against the outer peripheral surface of the locking segment v is biased on a spring member. Due to the radially projecting locking segment, a larger outer circumference of the locking segment is advantageously provided which allows a correspondingly better resolution for certain locking positions, without thereby increasing the overall dimensions of the locking sleeve and / or the dimensions of the locking sleeve receiving opening. In the case of a latching locking characteristic this can be changed by replacing the locking sleeve with otherwise unchanged hinge, e.g. for different vehicle models.

The outer circumferential surface may extend over an angular range, the maximum opening angle of the vehicle door, usually about 75 degrees 90 degrees, corresponds. The outer circumferential surface protrudes radially relative to the remaining circumference of the locking segment in the manner of an angular segment, whereby the boundary surfaces of the angle segment, which connect the outer peripheral surface with the sleeve part of the locking sleeve, at the same time form the stop for maximum and minimum opening angle. The rest of the circumference of the locking segment is in this case formed essentially as a cylindrical shell portion, which is received in a correspondingly small-sized portion of the opening of the hinge half. It is possible that the rest of the circumference at the same time the storage in this opening is used to support the pivoting or rotational movement of the angle segment, but it is preferably provided that the entire circumference of the locking sleeve is arranged spaced from the opening, and thus possibly the abutting Limiting surfaces of the locking segment against parts of the opening come into abutment - this friction and noise and an undesirable change in braking force is avoided with changing tribological parameters.

By providing the angle segment, which has at least a 20% larger radius than the rest of the circumference of the locking segment, a correspondingly large resolution is achieved in the region of the outer peripheral surface, wherein the opening for receiving the sleeve with the locking segment can be made smaller because the locking segment only passes over an angle that corresponds to twice the opening angle of the vehicle door, and thus is usually less than 180 degrees. Thus, in particular the critical dimension, namely the distance of the contact plane of the hinge half with the door frame or the motor vehicle door to the remote end, turn out smaller. Furthermore, the mass of the sleeve connected to the hinge pin is less than a sleeve which completely occupies the radius of the outer peripheral surface of the locking segment. The outer peripheral surface may have recesses or grooves running parallel to the hinge axis which define preferred detent positions, but may also have substantially unrestricted circumferential profiling to provide stepless locking in a plurality From opening angles of the vehicle door to achieve a lock. Due to the fact that, as a rule, over the entire course of the opening movement of the door, the brake member engages with the outer circumferential surface of the locking segment, it follows that an escape space for the locking segment only has to correspond approximately to the angles of the segment. Preferably, the front in the direction of movement boundary of the locking segment abuts against a stop surface of the opening, so that not only the locking device is integrated into the hinge half, but also the end stop.

Advantageously, it is provided that the outer circumferential surface of the locking segment a plurality of holding positions, for example in the form of grooves, and that the holding positions are also provided radially outwardly opposite the periphery of the locking sleeve outside the locking segment. This ensures, inter alia, that the spring acting on the brake member is not completely relieved when it penetrates into a groove of the outer circumference.

It is possible to line the stop face with metal to prevent wear. The reinforcement of the abutment surfaces in the region of the opening in which the angular segment is received, can be made by folding a sheet metal portion of the legs of the bending part, but suitably a metal clip is used, which connects the two abutment surfaces via a base which covers the segment. This can, if the insert is manufactured as an injection molded part, also already be injected into the insert. The base covers the segment, so that the hinge pin with attached sleeve can be inserted from below into the opening of the hinge half without the parts colliding.

Conveniently, the locking sleeve on which the locking segment is arranged, made of metal such as steel, so that a high wear resistance. Alternatively, it can also be a ceramic sintered part whose shape is possible near the final contour. The locking segment preferably has a central, continuous bore, which allows a connection to the hinge pin. For this purpose, the cylindrical inner circumference of the bore is expediently provided with a knurling which makes it possible to press the sleeve onto a section of the hinge pin so that it is connected to one another in a rotationally fixed manner. Accordingly, upon rotation of the hinge pin, the angle segment is rotated along the brake member, and due to the bias of the brake member generates a corresponding braking force.

The insert preferably has an appropriately through opening penetrated by the hinge pin, which makes it possible to axially insert the locking sleeve with the projecting locking segment, so that the hinge pin need not be split in the region of the sleeve.

Preferably, the opening in a plane normal to the hinge axis has a first portion and a second portion, wherein the periphery of the opening in the first portion is provided closer to the hinge axis than in the second portion. The opening has a first portion with a small radius in which the locking sleeve is peripherally bordered, and a second portion with a larger radius than the first portion in which the angle segment is pivotally mounted at an angle. The first portion has a smaller diameter than the second portion, wherein the second portion is substantially facing the stop plane of the hinge half on the door frame. As a result, the distance between the stop plane of the hinge half to a door assembly part and the distal end of the hinge half, in which the hinge pin extends and which is also referred to as a head roller, reduced and correspond to a smaller installation space required.

Preferably, the second portion of the opening is dimensioned such that the locking segment is always in engagement with the brake member regardless of an opening angle of the two hinge halves, a spin and thus disengage the two parts of the locking device is prevented. The step between the first section and the second section of the opening can advantageously limit the locking segment in its pivoting angle.

In the insert a guide channel is expediently provided, in which the brake member is axially displaceable and guided, wherein the guide channel connects the second portion of the opening with a front side facing away from the first portion of the insert. The axes of the guide channel and the opening are expediently arranged perpendicular to each other to allow radial delivery of the brake member. But it is alternatively also possible that the guide channel is formed as a blind hole, against the closed end, the spring member which biases the brake member is supported.

According to a preferred embodiment it is provided that a support for the end remote from the braking member of the spring member in its axial position in the insert is adjustable to adjust the bias of the spring member and thus achieved between the braking member and outer peripheral surface of the locking segment braking torque. The support can be adjusted in various ways, for example by the provision of spacers or by a threaded connection, but preferably the support has a projection facing away from the spring member, which is adjustably fixed in an opening of the support structure to adjust the bias of the spring , It is possible to fix the extension in the set position against the support structure, but preferably the extension is at the same time designed as a fastening means for the hinge part on the motor vehicle door or the door frame, so that the fixing of the adjustment of the bias of the spring force with the connection of the hinge part to the corresponding door assembly part, motor vehicle door or door frame, takes place. The attachment to the door assembly part can be done for example by riveting one end of the extension, whereby the extension of a further rotation and thus a change in the Pre-tension of the spring member is prevented. Another mounting option is to set a threaded end of the extension with a nut or a countered nut assembly.

According to a preferred aspect, a part of the locking device is at the same time a fastening means for the hinge half on the motor vehicle door or door frame. According to another preferred aspect, an axis of an opening for a fastening means of the one hinge half with an axis of the hinge pin biases a plane in space.

The provision of a fastener that extends in the extension of the guide channel and the brake member and thus has no lateral offset and thus no moment against the load or the shortest connecting line hinge axis mounting plane allows the support structure slightly less massive and thus with to train less weight.

It is further possible to form the region in which the projection or the fastening means is connected to the support structure with a somewhat greater thickness, for example by means of a pull-through, which produces a thickening of the mass of the base of the support structure in the region of its opening, which is designed to be more stable. The passage in this case has a diameter which is smaller than the diameter of the guide channel, but is preferably adapted to the diameter of the guide channel, so that when inserting the insert at the same time an additional positive fixation of the insert takes place on the support structure. The extension, which is also designed as a fastening means and which penetrates the base of the support structure, also fixes the insert on the support structure. It is possible to provide by the adjustability of the support up or reduced braking torques for the hinge in a particularly advantageous position for dip painting. In this case, the hinge can be provisionally fixed to the door frame by means of the fastening means.

Preferably, the fastening means passes through an opening of a hinge half, and the opening is aligned with a at least a portion of the locking device receiving guide channel.

Preferably, in the embodiment of the support structure, the eye is provided as a bent sheet metal part in the leg of the bent sheet metal part. The eye is lined for this purpose with a socket, which ensures the rotational mobility of the hinge pin in the hinge half. If the bent sheet metal part has two legs, the hinge pin is expediently mounted in a rotatable manner in each case in one eye of each of the two legs with a corresponding collar bushing. At the same time, the leg (s) advantageously delimits axially the opening which is formed in the insert as a continuous opening, so that the receptacle for the securing device is suitably encapsulated against the ingress of contaminants. Conveniently, the hinge pin is riveted on one side of the leg facing away from the other hinge half, wherein this can be done directly on the collar part of the bush designed as a collar bushing. As a result, the insert and the support structure are advantageously clamped axially, so that the ingress of contaminants on the mutually facing surfaces of the legs and the insert is effectively avoided. If this seal is not sufficient, for example, to prevent the ingress of liquids, a sealing tape can be inserted between said parts, which can alternatively be vulcanized on one of the surfaces of support structure and use.

An alternative locking device which does not form part of the invention comprises a locking ring which is non-rotatably connected to the hinge pin and rotates therewith, and a concentric cam ring which is biased by a spring against the locking ring having facing axial surfaces and which generate a braking force with mutual rotation. The spring may be indirectly or directly supported against insert or support frame.

The vehicle hinge is expediently designed as Einelenkscharnier, in which a hinge half can be fixed to a first door assembly part, and the other hinge half can be fixed to the other door assembly part. For this purpose, in the other, not provided with the locking device hinge half a double-cone-shaped opening may be provided, in which a cone portion of the hinge pin from one side and a conical portion having bolts can be inserted from the other side, so that the hinge is lifted altogether. Alternatively, a hexagonal recess is provided in the other hinge half, in which a hexagonal portion of the hinge pin can be inserted with a central threaded bore for receiving a bolt. The other hinge provided with the double cone or the hexagonal recess may also have a support structure and an insert, for example in which the support structure provides the two conical surfaces and is otherwise formed as a sheet metal bent part, while the insert fills the support structure and thus prevents this bends under the load. Under certain circumstances, even the same or a similar use as for the hinge half can be provided with the locking device, but in which no locking device is provided. It is also possible to provide a locking device in both hinge halves, for example, when larger opening angle than the usual about 80 degrees are desired, or to provide with the other locking device a preferred stop position for the dip painting, which is no longer needed in the subsequent driving.

Alternatively, it is also possible to form the motor vehicle hinge as a multi-joint hinge, in particular four-bar hinge, in which the actual hinge halves, which are fixed to the door assembly parts, are connected to each other via two links. Then, the handlebar drives the hinge pin, which is fixed in the one hinge half to the locking device in preferred holding positions. Such four-bar hinges are used for example in hoods and tailgates.

In one aspect, the motor vehicle hinge further includes a first hinge half attachable to one of the vehicle door and door frame, a second hinge half attachable to the other of the vehicle door and door frame, and a hinge pin hingedly connecting the two hinge halves, at least one the two hinge halves has a support structure and an insert, and that the support structure and the insert are mutually fixed. This advantageously two properties of the hinge half, namely the possibility to accommodate the locking device and the provision of a load bearing, separated into two different parts that are mutually fixed and thus act as a part. Here, the hinge pin is mounted on at least one eye of the support structure. Expediently, but not necessarily, the support structure and the insert have a different density, so that overall a part which is lighter in weight relative to a solid part is created.

Preferably, the motor vehicle hinge comprises a locking device which acts in the insert, that is at least predominantly accommodated therein. The locking device sets the two hinge halves mutually releasably fixed in at least certain pivot angles. This may be a latching locking device that provides preferred brackets in which a spring member is relatively relaxed by a brake member engages therein. This can also be a stepless locking device, which generates different braking torques depending on the set profiling in the corresponding opening angle. Furthermore, the locking device may also be a device that secures the pivotal movement of the door by a uniform braking torque against impact by wind gusts. Combinations of the above versions are possible.

The volume-consuming housing of the locking device is essentially effected by the use, while the inclusion of the loads, which are essentially introduced by the gravity introduced into the hinge half the door and the introduction of the weight of the hinge in the door frame or the vehicle door is characterized, carried by the support structure. The insert, which has to absorb only small loads, such as the guiding or storing components of the locking device, can be made of a lightweight, less expensive and especially light or even non-machinable material, while the weight and the volume of the support structure on the male Weight can be designed and thus is not oversized. This results in a significant weight saving, which reduces the weight of the vehicle and its fuel consumption accordingly.

Preferably, the support structure is formed as a metal part, while the insert is formed as a plastic part. Both materials have favorable properties in terms of formability, manufacturability and weight for the specific requirements, so that the resulting motor vehicle hinge is sufficiently stable to absorb the loads, and yet not oversized. Conveniently, the insert is fixed to the support structure, for example, positive or non-positive, but alternatively also by gluing or by cohesive bonding. In particular, the hinge half can be produced in that the support structure consists of one or more metal parts, which are encapsulated in an injection mold with plastic, or of a plastic part, in which the support structure is used in corresponding guides in one or more parts.

Preferably, the support structure is formed as an L-shaped or U-shaped bent part of sheet metal and has a base and at least one, preferably two legs perpendicular to the base. The bent part thus forms a frame which comprises the insert and into which the insert can be inserted. Here, the at least one leg is preferably penetrated by the hinge pin, so that the storage of the hinge pin takes place on the support structure and so forces and loads are at least predominantly introduced into the support structure. This is expediently provided that the base of the bending part of the door frame, or alternatively the door, is assigned, and correspondingly at least one opening for attachment to the corresponding door assembly part, motor vehicle door or motor vehicle door frame having. As fasteners threaded rods, rivets, bolts, screws or the like come into consideration. In the event of subsequent disposal, the insert and the bent part are easier to separate than components coated with plastic, so that simple recycling after separation is possible.

It is possible to produce the insert in several parts, but this is preferably formed in one piece, which is easily possible by injection molding or by casting. If blind holes, undercuts or the like are to be provided in the insert, this can be composed of two halves, for example divided along a longitudinal axis, which are put together. It is also possible, the cavities, but also the contours in which the locking device or its parts are arranged to create from the solid material by machining such as milling, but it is easier to provide appropriate cores during injection molding; It should be noted that the cores often have a very slight cone for easy removal, and the corresponding cavities, such as channels or openings, then also have a slight cone. If the cores are introduced from two sides, it can also be a double cone whose diameter decreases inwards.

Preferably, the insert in the direction of the base of the support structure in the support structure can be inserted, whereby a simple assembly is ensured. In this case, the support structure preferably has a latching means which penetrates into a recess of the insert and cleats the insert on the support structure. As a result, a positive fixation is given, which fixes the insert and the supporting structure for the further assembly of the hinge. It is possible, provided by the legs of the bent part folded metal strips on the type of attacks, which limit the use in a further plane when it is inserted into the support structure and thus fix the two parts in another direction each other. Alternatively, the legs may have embossments which engage in detenting or clip-like manner into corresponding boundary surfaces of the insert or recesses therefrom. The insert expediently has a broadening on the end facing away from the base, which prevents the insertion being used in the wrong direction during automatic insertion into the supporting structure, for example by robots or the like.

According to one aspect, there is provided a method for making a hinge half, and preferably for subsequent connection to another hinge half for making a motor vehicle hinge, comprising the steps of: (S1) placing a locking sleeve of a locking device in an opening of an insert; (S2) inserting the insert together with the locking sleeve in a support structure, whereby the locking sleeve can not escape from the opening; and (S3) passing the locking sleeve and the support structure with a hinge pin.

Preferably, the other components of the locking device are introduced into the insert before the insertion step (S2). The central bore of the locking sleeve, which is optionally circumferentially spaced from the opening, is preferably positioned aligned with eyes of the support structure so that the hinge pin can be inserted in a hub and riveted at its end. Since the locking sleeve is pressed onto a portion of the hinge pin, either a positioning aid through the eye of the support structure hold the locking sleeve centered and act upon; but preferred is an auxiliary mandrel an eye and fix the central bore of the locking sleeve mutually, the force acting on the locking sleeve force for pressing the hinge pin is indirectly transmitted via the support structure on this, and upon penetration of the hinge pin, the mandrel is ejected or pulled out.

Further advantages, features, properties and developments of the invention will become apparent from the dependent claims and from the following Description of preferred embodiments.

In Fig. 1 to 7 a hinge 1 is partially shown, which has a first hinge half 10 and a second hinge half 20 shown only schematically, the first hinge half 10 is fastened to a direction indicated by a dotted line door frame 10a, and the second hinge half 20 to one by a dash-dotted line indicated motor vehicle door 20a is fastened. The two hinge halves 10, 20 are hinged together by a hinge pin 30 which is rotatably mounted in the first hinge half 10 and which is rotatably fixed in an opening of the second hinge half 20.

The first hinge half 10 comprises a support structure 11 designed as a U-shaped sheet metal bent part and an insert 12 insertable into the support structure 11. The support structure 11 comprises a base 110, of which an angled leg 90 and an upper leg 114 are angled by approximately 90 degrees protrude. Provided in the base 110 is a first aperture 110a covered by the insert 12 and a second aperture 110b provided adjacent and spaced from the insert 12. The side facing away from the insert 12 of the base 110 is in this case applied to the contact edge of the door frame 10a, and fasteners such as screws, bolts or rivets pass through the openings 110a, 110b, which will be explained in more detail below. The support structure 11 is formed overall angularly, wherein the one leg of the angle is U-shaped folded and in the extension direction of the base 110, and the other leg of the angle is formed by the two legs 112, 114, see. especially Fig. 3 ,

Of the legs 112, 114 is angled by 90 degrees and a plane perpendicular to the legs 112, 114 and perpendicular to the base 110 occlusive on both sides a 90 degree angled stop 112a, 114a, 112b, 114b in front, the pairs a lateral boundary for the insert 12, the stops 112a, 114a on the one hand of the insert 12 and the stops 112b, 114b on the other hand of the stop, see. especially Fig. 2 , Between each stop 112a, 112b, 114a, 114b and the flat extent of the legs 112, 114, four arcuate metal sections connecting the stops 112a, 112b, 114a, 114b to the legs 112, 114 are formed, which are at an exact right angle protrude inwardly and thus form latching means which can engage in corresponding recesses 122 in the insert 12, which will be explained later.

The insert 12 is made of one - optionally transparent or opaque - plastic injection molded as a one-piece part and has a parallelepiped portion 120 which faces the base 110, and a cantilevered portion 121 which faces away from the base 110, which as one-piece injection molded part are formed. An end face 120a of the cuboid-shaped portion 120 facing away from the projecting portion 121 has a rounded transition 120r to the parallel upper and lower boundary surfaces 120b, 120c of the parallelepiped-shaped portion 120 and the projecting portion 121 of the insert 12, which is adapted to the radius between the base 110 and the legs 112, 114. The lateral boundary surfaces 120d, 120e of the cuboid portion 120 are spaced so that they can be inserted between the stops 112a, 114a on the one hand and 112b, 114b on the other hand, wherein at the height of the stops with the legs 112, 114 connecting metal portions recesses 122 in the Insert 12 are recessed, which allow a snap of the compounds and thus allow a positive fixing of the insert 12 in the support structure 11.

The projecting portion 121 of the insert 12 has an opening 123 passing through the wide boundary surfaces 120b, 120c, which has a first section 123a which has a radius about the hinge axis A indicated by dash-dotted lines, and a second section 123b with a second section 123b. 60% larger radius than that of the first portion 123a, with the first portion being slightly more than 180 degrees and the second portion 123b being slightly less than 180 degrees opening angle, as shown in the cross-sectional view of FIG Fig. 5 clearly visible. A cylindrical guide channel 124 connects the end face 120a and the second portion 123b of the opening 123, wherein the guide channel 124 has a diameter which is more than half the distance of the wide boundary surfaces 120b, 120c.

In the insert 12, a locking arrangement 40 is housed completely or at least predominantly. The locking arrangement 40 comprises a locking sleeve 41 having a central bore 41a and a locking segment 410, which protrudes radially over the remaining circumference 41b of the locking sleeve 41 in the manner of an angular segment. The locking sleeve 41 is made of steel and has in the region of its central bore 41 a knurling, which allows a pressing on a portion 30 a of the hinge pin 30.
