Description

Motor vehicle hinge

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 suitable for the articulated

Connection of a motor vehicle door to a door frame can be used. 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 has a

Hinge pin articulated with a second hinge half, which is attachable to the door, is connected. 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 in from the solid material of the first

Hinge half recessed cavities introduced, wherein the brake member defines with the recesses or grooves provided on the circumference of the sleeve preferred opening angle of the door. A disadvantage of the known

Motor vehicle hinge is the fact that to achieve certain pivoting angle of the motor vehicle door, the diameter of the sleeve is sized large, 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

To create cavities such as channels and openings, which allow the integration of the locking device 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

Confirmation copy | 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, the preferred opening angle of the

Vehicle door define in the wrong places are arranged. 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 each fastened to the motor vehicle door or the door frame and are hingedly connected to each other via a hinge pin. A locking device which fixes the two hinge halves mutually releasably in at least certain pivoting 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. Is the sleeve by pivoting the door

twisted 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 as an integral solid metal part is formed, which is heavy and in the tough material, the cavities for the arrangement of

Components of the locking device must be introduced by machining. 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 disposed on the hinge pin, which with a

Brake member, which is deliverable radially to the sleeve, generates a braking force for the door. 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, which contributes to the hinge half made of solid material with integrated locking device, in addition to the complicated cavities must be introduced to the

Accommodate 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 can be fastened to a door, and a second hinge half, which can be fastened to a door frame. 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 socket on. 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.

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 one aspect of the invention, there is provided a motor vehicle hinge comprising a first hinge half attachable to one of the motor vehicle door and door frame, a second hinge half attachable to the other of the motor vehicle door and door frame, and a hinge pin hingedly connecting the two hinge halves wherein at least one of 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 supporting structure and the insert have a different density, so that overall a lighter-weight part is created compared to a solid part. 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, depending on the set profiling in the corresponding opening angle different

Braking moments generated. 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. Also

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 is characterized essentially by the force introduced into the hinge half weight of the door and the introduction of the weight of the hinge in the door frame or the motor vehicle door, through the Support structure takes place. 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 is the weight of the vehicle and its

Fuel consumption reduced accordingly.

Preferably, the support structure is formed as a metal part, while the insert is formed as a plastic part. Both materials have for the

specific requirements in terms of moldability, manufacturability and weight, so that the resulting motor vehicle hinge is sufficiently stable to accommodate the loads, and yet not oversized. Conveniently, the insert on the support structure fixed, 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 designed as an L-shaped or U-shaped bent part

Molded sheet metal and has a base and at least one, preferably two perpendicular to the base leg. 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 bent part of the door frame, or alternatively the door, is assigned, and corresponding 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 easier However, it is 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 sheet metal strip on the type of attacks that 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 embossings, the latching or clip end in corresponding boundary surfaces of the insert or

Snap recesses from it. 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 of 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 attached to the other of

Motor vehicle door and door frame is fastened, a hinge pin which connects the two hinge halves articulated, and arranged in one of the two hinge halves locking device, the two

Hinge halves mutually releasably fixed in at least certain pivot angles, wherein the locking device associated with the hinge pin locking sleeve and cooperating with the locking sleeve brake member wherein the locking means comprises a hinge pin associated with the locking sleeve with a radially projecting locking segment and 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 is biased by a spring member. The radially projecting locking segment advantageously provides a larger outer circumference of the locking segment, which allows a correspondingly better resolution for certain locking positions, without thereby reducing the overall dimensions of the locking sleeve and / or the

Overall dimensions of the locking sleeve receiving opening to increase overall. 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, which corresponds to an opening angle of the motor vehicle door, usually about 75 degrees, a maximum of 90 degrees. 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 angular segment, which is the outer

Connect circumferential surface with the sleeve part of the locking sleeve, at the same time form the stop for maximum and minimum opening angle. The rest

The circumference of the locking segment is essentially formed 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 assist the pivoting or rotational movement of the angle segment, but it is preferably provided that the entire circumference of the

Locking sleeve is arranged at a distance from the opening, and thus at most the abutting boundary surfaces of the locking segment against parts of the opening in abutment - thereby friction and

Noise development and an undesirable change in the braking force with changing tribological parameters avoided. By providing the angle segment which has at least a 20% larger radius than the remaining circumference of the locking segment, a correspondingly large resolution in the region of the outer

Reached peripheral surface, wherein the opening for receiving the sleeve with the locking segment can be sized 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 between the contact plane of the hinge half with the door frame or the motor vehicle door to the

turned away end, 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 can be parallel to the hinge axis running

Recesses or grooves, which define preferred locking positions, but it can also be a substantially ungestufte

Have circumferential profiling to achieve a continuous detection in a variety of opening angles of the vehicle door of 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.

It is advantageously provided that the outer peripheral surface of

Locking segment has a plurality of holding positions, for example in the form of grooves, and that the holding positions are also provided radially outwardly relative to the circumference 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 around one

Prevent wear. The reinforcement of the abutment surfaces in the region of the opening in which the angular segment is received can be effected by folding off a sheet metal section of the legs of the bent part,

It is expedient, however, to use a metal clamp 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 exists. 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 on, which allows a connection to the hinge pin. For this purpose, the cylindrical inner circumference of the bore is expediently with a

Knurling equipped, which allows a pressing of the sleeve on a portion of the hinge pin, so that they are rotatably connected to each other. 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 allows the

Insert locking sleeve axially with the projecting locking segment, so that the hinge pin in the region of the sleeve need not be divided.

Preferably, the opening in a plane normal to the hinge axis has a first portion and a second portion, wherein the periphery the opening in the first section is provided closer to the hinge axis than in the second section. 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 the stop plane of

Hinge half facing 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 independent of an opening angle of the two

Hinge halves is always in engagement with the brake member, a spin and thus disengage the two parts of the locking device is thus prevented. The stage between first section and second

Section of the opening can be advantageous the locking segment in his

Limit swivel 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 the braking torque achieved between the brake member and the outer peripheral surface of the locking segment. 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, done. The attachment to the door assembly part can be done, for example by riveting one end of the extension, whereby the extension is prevented from further rotation and thus a change in the bias of the spring member. 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

Doorframe. 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 extending in the extension of

Guide channel or the brake member runs and thus has no lateral offset and thus no moment against the attacking load or the shortest connecting line hinge axis attachment plane, makes it possible to form the support structure a little less massive and thus with less weight. It is also possible to form the region in which the projection or the fastening means is connected to the support structure with a slightly greater thickness, for example by means of a pull, which thicken the mass of the base of the support structure in the region of

Breakthrough generated, 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, by the adjustability of the support up or

reduced braking torques for the hinge in one for the

Dip painting to provide particularly advantageous position. 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, the eye is in embodiment of the support structure as

Sheet metal bending part is provided in the leg of the sheet metal bending 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 in each case in one eye of each of the two legs with a corresponding collar bushing

rotatably mounted. 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 a side facing away from the other hinge half side of the leg, which directly on the collar part of the as Collar socket trained socket can be made. 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 comprises a locking ring which is non-rotatably connected to the hinge pin and rotates therewith, and a concentric cam ring, which by a spring against the locking ring

biased, which have mutually facing axial surfaces and which generate a braking force upon 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, a double-conical opening can be provided in the other hinge half not provided with the locking device, into which a cone section of the hinge pin can be inserted from one side and a bolt section having a cone section from the other side, so that the hinge can be raised altogether is. 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. Also the other, with the

Double cone or the hexagonal recess provided hinge may in this case have a support structure and an insert, for example, in which the support structure provides the two cone-shaped surfaces and is otherwise formed as a sheet metal part, while the insert fills the support structure and thus prevents them bends under the load , In certain circumstances can even be the same or a similar use as provided for the hinge half with the locking device, in which but no

Locking device is provided. It is also possible to have one

Provide 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 coating, 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.

According to one aspect of the invention, there is provided a method of making a hinge half, and preferably for subsequent connection to another hinge half for making a motor vehicle hinge, comprising the steps of (S1) locating a locking sleeve

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 through the locking sleeve and the support structure with a hinge pin.

Preferably, before the insertion step (S2), the others

Components of the locking device introduced into the insert. 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 on a section of the

Hinge pin is pressed, either a positioning aid through the Eye of the support structure keep the locking sleeve centered and apply; 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.

The invention will be explained in more detail below with reference to the accompanying drawings with reference to preferred embodiments. shows an exploded view of a first hinge half of a preferred embodiment of a motor vehicle hinge according to the invention.

In Fig. 1 to 7, a hinge 1 is partially shown, which is a first

Hinge half 10 and a second illustrated only schematically

Hinge half 20, wherein the first hinge half 10 can be fastened to a direction indicated by a dash-dotted line door frame 10a, and the second hinge half 20 to a direction indicated by a dash-dotted line 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. in particular also 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. 2). Between each stop 112a, 112b, 114a, 114b and the flat extension of the legs 112, 114, four bent metal sections which connect the stops 112a, 112b, 114a, 114b to the legs 112, 114 are formed. which protrude inwards relative to an exact right angle 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. A facing away from the projecting portion 121 end face 120a of the parallelepiped portion 120 has a rounded transition 120r to the parallel upper and lower

Boundary surfaces 120 b, 120 c of the parallelepiped 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 cantilevered portion 121 of the insert 12 has one of the widths

Boundary surfaces 120b, 120c passing through opening 123, which has a first portion 123a, which has a radius around the chain-dotted line indicated hinge axis A, and a second portion 123b with a 40-60% larger radius than that of the first portion 123a, wherein the first portion is slightly more than 180 degrees and the second portion 123b is slightly less than 180 degrees opening angle, as can be clearly seen from the sectional view of FIG. 5. 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

Defining surfaces 120b, 120c makes.

In the insert 12, a locking assembly 40 is wholly or at least mostly accommodated. The locking assembly 40 includes a locking sleeve 41 having a central bore 41 a and a locking segment 410 which projects radially over the remaining circumference 41 b of the locking sleeve 41 in the manner of an angular segment.
