Description

The invention generally relates to the control devices of the mechanism

  opening of an opening of a motor vehicle.

  More specifically, the invention relates in a first aspect to a method of mounting a control device of the opening mechanism of a motor vehicle door, on an inner side of the opening, the control device comprising at at least one housing and a movable control member relative to the housing between a rest position and an open position, the opening mechanism selectively adopting a locking configuration of the opening on the vehicle structure or unlocking and comprising a control cable provided with a sheath mounted fixed in the opening and a wire movable in translation inside the sheath, the control member comprising connecting means with one end of the wire and moving the latter; ci in a first direction from its rest position to its open position, the wire in turn passing the opening mechanism in its unlocking configuration.

  Control devices of this type are mounted, according to the prior art, by first inserting the end of the wire into the connecting means with the control member, then fixing the housing on the opening. This last operation is performed by first performing a translation in a transverse direction to engage the fastening tabs of the housing in orifices of the opening, then by a translation along a longitudinal direction to fix the tabs on the opening.

  The housing has at this stage a game of a few millimeters compared to the opening, longitudinally and vertically.

  The door trim panel is then mounted which has an opening in which the housing is housed (see FIG. 1). The panel carries guide fingers engaging in guiding areas of the housing and for centering it in the opening (area G, see Figure 2).

  Finally, a hubcap is mounted on the housing to hide the interface between the housing and the trim panel. This hubcap overflies both on the case and on the edges of the opening.

  This method has the defect of being slow. All the parts are mounted one after the other, the assembly time being very long and the costs generated being important.

  To minimize the number of mounting operations, it was thought to first mount the control device on the trim panel, then to set up the hubcap, then connect the wire to the control device, and finally to attach the trim panel and control to the door.

  In this case, it is difficult to connect the wire to the control device in a very difficult access zone. It is necessary both maintain the panel near the opening, grasp the wire in the narrow gap between the panel and the opening, and finally fix it on the control device, at a point generally not very accessible. Two editors are required to perform this operation, one to hold the panel and the other to make the connection of the wire on the controller.

  In this context, the present invention aims to overcome the defects mentioned above.

  To this end, the method of the invention, moreover in conformity with the generic definition given in the preamble above, is essentially characterized in that it comprises the following steps: 1 / Fastening on the sash an intermediate piece comprising first means for holding the end of the wire in position.

  The method aims to mount a control device 3 of the opening mechanism 2 of an opening 1 of a motor vehicle on an inner side of the opening.

  The control device 3 comprises a housing 30 for fixed mounting in the opening 1, and a control member 40 movable relative to the housing 30 between a rest position and an open position.

  The housing 30, as shown in Figure 2, is typically a molded plastic shell, including a recessed area on one side of said housing facing the interior of the vehicle.

  The control member 40 comprises a gripping portion 42 rotatably mounted on the housing 30 about a vertical axis 43, extending in the recessed area when the control member 40 occupies its rest position, and capable of to be grasped manually and pivoted inwardly of the vehicle to move the control member 40 to its open position (see Figures 2 and 8).

  The opening mechanism 2 selectively adopts a locking configuration of the opening 1 on the vehicle structure or unlocking, the opening 1 can be opened in unlocking configuration of the mechanism.

  This mechanism comprises a control cable 20 and a lock actuated by this cable, the cable being provided with a sheath 21 fixedly mounted in the opening 1 and a wire 22 movable in translation inside the sheath 21.

  The control member 40 comprises means 41 connecting with one end 221 of the wire 22, able to move the latter in a first direction when the control member moves from its rest position to its open position, the wire 22 in turn passing the opening mechanism 2 in its unlocking configuration. The first direction is represented by an arrow in Figure 8.

  The control member 40 is returned to the rest position by an elastic member 44, for example a clothespin spring wound around the axis 43, and comprises a stop, not shown, blocking the travel of the body of the control 40 at its rest position.

  According to the invention, the method comprises the following successive steps.

  1 / Fixing on the opening 1 of an intermediate part 50 comprising first means 51 for holding the end 221 of the wire 22 in position.

  2 / Placing the end 221 of the wire 22 in the first holding means in position 51.

  3 / Installation of the control device 3 on the opening 1, in a first movement for establishing the connection between the end 221 of the wire 1 and the connecting means 51 of said wire with the control member.

  4 / Movement of the control device 3 in a second movement to release the end 221 of the wire 22 of the first holding means 51 of the intermediate piece 50.

  Preferably, the intermediate piece 50 also comprises second means 52 for holding in position a stop end 211 of the sheath 21, the case 30 comprising means 31 for fixing the stop end 211, the method comprising, after step 2 /, a step 2 '/ of putting the stop end 211 on the second holding means in position 52, the first movement making it possible to fix the stop end 211 in the fastening means 31 and the second movement to disengage the stop end 211 of the second holding means 52 of the intermediate piece 50.

  The first and second movements further allow attachment to the opening 1 of the housing 30 of the control device 3.

  More specifically, as seen in Figure 5, the opening 1 comprises a metal door liner 11 on which is fixed the housing 30, and a reinforcing profile 13 fixed on an outer side of the liner 11 on which is fixed the intermediate piece 50.

  This metal profile has a U-shaped section and extends substantially longitudinally, the open side of the U being pressed against an outer face of the liner 11, so that the reinforcing profile 13 constitutes with the door liner 11 a closed channel inside which the control cable 20 travels from the control member 40 to the lock of the opening mechanism.

  The intermediate piece 50 is fixed on the bottom of the profile 13, which extends parallel to the lining, so that the first and second holding means 51/52 are engaged in an opening 111 formed in the door liner 11, as can be seen for example in Figure 9.

  The intermediate piece 50 is a plastic molded part, represented in FIG. 4, comprising, in addition to the first and second holding means 51 and 52, a base structure 53 and two fastening fingers 54. The basic structure 53 has the shape a U-shaped section, provided with a central core 531 extended by two wings 532 opposite.

  FIG. 5 shows that the intermediate piece 50 rests by the free edges of the two wings 532 on the bottom of the profile 13, the two fingers 54 protruding from the central core 531 between the two wings 532 and engaging with free ends in the fixing holes 131 formed in the bottom of the section 13, these free ends bearing relief finger locking in the orifices.

  The first and second holding means in position 51 and 52 are formed on one face of the central core 531 opposite fingers 54.

  The end 221 of the wire 22 is shaped in a cylindrical barrel, of axis perpendicular to the wire, the wire extending substantially in a median plane of the barrel as shown in Figure 10.

  The first holding means 51 consist of two flat front clips 511, extending in respective horizontal planes parallel, mutually spaced in a first vertical direction. These staples 511 each comprise a housing 512 circular receiving the barrel. The housing 512 has an opening in a second longitudinal direction, perpendicular to the first, the two edges of the opening having a spacing slightly smaller than the diameter of the barrel, so that it can be engaged forcibly in the housing. The cask can also be released from the housing when there is sufficient stress in the second longitudinal direction.

  The end 221 is put in place in step 2 / in the clips before 511 by placing the barrel vertically and by inserting its two ends into the housings 512 of the front clips 511, the thread 51 then extending longitudinally between the two front staples 511.

  The second holding means 52 consist of a rear clip 521 for receiving the stop end 211 of the sheath 21.

  FIGS. 5 to 8 show that this stop end 211 is rigidly fixed in a cylindrical ring 212.

  The rear clip 521 consists of two jaws mutually spaced in the first vertical direction, able to grip the ring 212 between them.

  These jaws are straight rods, mutually parallel, extending transversely from the central core 531, each bearing a relief facing the other jaw at a free end.

  FIG. 11 shows that the cylindrical ring 212 has two mutually parallel cut faces 213 extending on two diametrically opposite sides of the ring, extending by respective shoulders 214 extending in the same plane intersecting the cylinder on a diameter.

  The stop end 211 is placed in step 2 '/ placing the ring 212 so that its axis is longitudinal, and forcing the cylindrical ring 212 between the two jaws 522. The reliefs of the jaws 522 slide along the cut faces 213 and rest on the shoulders 214, so that these reliefs maintain the ring at the bottom of the rear clip 521.

  The rear clip 521 is disposed in the longitudinal extension of the front clips 511.

  The connecting means 41 of the control member 40 with the end 221 in the barrel of the wire 22 consist of an arm 411 secured to the gripping portion having a staple-shaped end 412. This arm 411 extends towards the outside from an area of the gripping portion 42 near the axis 43, and through the recessed area of the housing through an opening provided for this purpose.

  This clip 412 has exactly the same general shape as the front clips 511, extends in a horizontal plane, but is open on one side rotated in a third outer transverse direction, perpendicular to the first and second directions, when the command 40 is at rest.

  This clip 412 is inserted between the front clips 511 of the intermediate part 50, the spacing between the front clips being chosen sufficiently large for this purpose.

  Moreover, the fastening means 31 of the housing consist of a zone forming a gripper, able to irreversibly engage in a complementary zone 215 of the ring 212.

  Finally, it will be pointed out that the housing 30 comprises L-shaped tabs 32 for fastening said housing to the door liner 11.

  In step 3 /, the control device 3 is set up according to a first movement which is a translation in a direction transverse to the outside, represented by the arrow of FIG.

  It can be seen by comparing FIGS. 5 and 6 that the housing 30 comes to rest with a flat web 33 against the door liner 11, the L-shaped lugs coming into holes 112 formed in the liner 11 (see the holes on FIG. 9), that the clip 412 of the control member engages the cask by sliding between the two front clips 511 of the intermediate piece 50, and that the fastening means 31 of the casing 30 engage the complementary area 215 of the ring 212. At the end of this first movement, the cask is engaged in the housing 413 of the clip 412.

  The second movement is a translation in a longitudinal direction in the first direction, that is to say in the direction of movement of the wire 22 corresponding to the unlocking of the opening mechanism, represented by the arrow of FIG.

  It can be seen in FIG. 7 that the fastening tabs 32 pinch the edges of the holes 112 against corresponding zones of the planar web 33 of the casing 30, thus ensuring the attachment of the casing to the liner.

  This same movement makes it possible to disengage the cask from the housings 512 of the front clips 51, the clip 412 of the control member 40 driving the cask in the longitudinal direction, that is to say exactly on the open side of the receiving casing. 512 staples before 51.

  This second movement also makes it possible to disengage the stop end 211 of the rear clip 521, the fastening means 31 cooperating with the complementary zone 215 of the ring 212 to allow the longitudinal translation drive of this ring 212. , this sliding between the two jaws 522 until the ring 212 completely out of the rear clip 521.

  We are then in the situation of Figure 7, the ring 212 extending in the space between the front clips 511 and the rear clip 521 and being rigidly fixed to the housing by the fastening means 31, the sheath 21 passing through the rear clip 521 so that it provides guiding of the sheath 21.

  It can be seen in FIG. 8 that the control device is then operational. The pivoting of the gripping portion 42 of the control member 40 towards the interior of the vehicle drives the arm 411 in rotation, the latter driving the wire through the staple 412.

  In the rest position of the control member 40, the arm extends from the axis 43 in a direction inclined both outwards and towards the intermediate piece.

  When the control member 40 moves from its rest position to its open position, the arm 411 is rotated in the first direction, corresponding to the clockwise direction in FIGS. 5 to 8, which brings it into a substantially directional orientation. cross. The wire thereby undergoes a movement corresponding approximately to a translation in the first direction, which moves the barrel away from the intermediate piece 50.

  Furthermore, it is known that the opening normally comprises, in addition to the door liner 11, a lining panel 12 which is fixed on an inner side of the liner and covers it almost entirely. This panel has a mainly decorative function, and allows to hide the functional organs of the opening.

  In a particularly interesting variant, not shown, the method comprises a step 0 / fixing the housing 30 on the trim panel 12, the first and second movements for fixing both the trim panel 12 and the housing 30 on the door lining 11.

  Step 0 / precedes step 1 /. The housing 30 is fixed to the trim panel by any suitable means, for example staples, on an outer side of this panel. The hollow area of the housing and the gripping portion of the control member are inserted into a hole cut in the panel for this purpose. The hubcap for hiding the interface between the housing and the panel is preferably integrated with the panel, and therefore does not form an independent piece to report on the panel.

  The panel is fixed to the door liner by any suitable means, for example by staples of the same type as the fastening lugs 32 of the housing 30, engaging in corresponding holes in the lining by the first movement, and pinch the edges of the holes by the second movement.

  The method described above may have multiple variants without departing from the scope of the invention.

  The control member can move from its rest position to its open position by a translational movement or a rotational movement about a longitudinal axis, transverse or any other orientation.

  The second movement is preferably a translation in the longitudinal direction, but can also be a vertical or oblique translation in a longitudinal vertical plane. The skilled person can easily adapt the orientation of the staples to the direction of the second movement.

  The opening preferably comprises a reinforcing profile, but may also be devoid of it. The intermediate piece is then fixed in a suitable area of the door liner.

  The stop end of the sheath is preferably rigidly fixed to the housing. However, it can also alternatively be fixed on the door liner. The intermediate piece then comprises only the first holding means in position. In step 2 '/ the stop end is fixed in its final position on the liner.

  It is therefore clear that the method described above and the opening constituted by this method have multiple advantages.

  The method facilitates and speeds up considerably the mounting of the control device on the sash.

  The total number of operations to be performed is decreased, in particular due to the integration of the hubcap in the trim panel.

  Fixing the wire on the control member and the sheath on the housing is very easy, since the wire and the sheath are held in appropriate positions by the intermediate piece. The operator only handles the trim panel, and must not hold the control cable. Only one operator can edit.

  Moreover, the method is particularly suitable for mounting control devices in the areas of difficult access of the opening.

  The control cable runs in a closed channel constituted by the reinforcing profile plated on the door liner. Access to the control cable of the opening mechanism is made particularly difficult for malicious people wanting to get into the vehicle. Protection against theft and intrusion is thus reinforced.

  The control cable travels in the reinforcing section and will therefore be less stressed in the event of a side impact on the opening. Indeed, the environment of the cable is reinforced by the profile and will therefore be less deformed in case of impact. The cable will be less displaced, and the risk of opening the opening will be less. It can thus limit the excess cable length needed to reduce the risk of opening the door in case of impact.

  It should be noted that these advantages are obtained particularly economically, by using a simple plastic molded part.
