Description

I

  Device for controlling the opening of a vehicle door.

  The present invention relates to a device for controlling

  the opening of a vehicle door and the corresponding method.

  The door opening control devices are mounted either on the outside wall of the door in an opening provided for this purpose in the sheet metal, or on the inside wall of the door in an opening made for this purpose in the sheet metal or in a trim panel for said door. The control device is intended to control the locking or unlocking of a lock arranged at a distance, by means of a rod or, more generally, of a cable sliding in a sheath. The end of the sheath is fixed to a fixed part of the control device and the end of the cable is fixed to a mobile part. The end of the cable is

  generally provided with an end element facilitating its gripping.

  There is known, in the prior art, a so-called monobloc device comprising a housing fixed to the wall of the door and supporting an axis on which a pallet is articulated which can be actuated by the user of the vehicle. A portion of the pallet is provided with a housing intended to receive the end of the cable. The end of the cable is mounted in its housing by a transverse movement, then by a rotational movement around its end and finally by a pulling movement in the direction of the cable. Due to its complexity, mounting the end of the cable in its housing is difficult to automate. Due to the last pulling movement in the direction of the cable, there is always a clearance between the end of the cable and the pallet. In such a type of control device, a modification of the parts visible by the user generally results in a modification of the technical parts, that is to say not visible, in particular at the level of the movement of the housing of the end of the cable and therefore at the level of the cable itself. Thus a modification of the design of the control device will result not only in a modification of the parts not visible but also

by a modification of the cable.

  There are also known control devices made in two parts which are mounted by first installing the pallet in the vehicle door and then fixing, around the pallet and interlocking with it, a housing. However, the mounting of the housing on the vehicle door and around the pallet is relatively delicate and leaves behind mounting clearance which adversely affects the finish of such a device. The object of the present invention is to provide a control device which overcomes these various drawbacks by allowing a quality finish with precise assemblies between the parts visible by the user, by allowing the modification of the visible parts of the device while retaining technical parts

  universal and offering improved resistance to burglary.

  The device for controlling the opening of a vehicle door, according to the invention, is intended to be mounted in said door and comprises a housing arranged in an opening provided in a wall of the door, a pallet pivoting around an axis integral with the housing and comprising a gripping portion and a fork, and a control cable provided with an end element cooperating with the fork of the pallet, the cable being disposed in a sheath ending in an endpiece integral with the housing. The end piece comprises means for guiding the end element of the cable during its movement under the action of the fork so that the trajectory of the end element is independent of the housing and the pallet of the device. . A control device is thus obtained,

assembly is economical.

  In one embodiment of the invention, the housing comprises a front face in contact with the pallet and a rear face

  provided with means for fixing the end piece.

  Advantageously, the end piece comprises elastic tabs which can be housed in corresponding windows of the housing. In one embodiment of the invention, the end piece comprises a concave curved portion provided with a rib capable of guiding the end element of the cable during its movement under

  the action of the pallet fork.

  In another embodiment of the invention, the end piece comprises a flat portion provided with a rib capable of guiding the end element of the cable during its movement under the action of

the pallet fork.

  In one embodiment of the invention, the fork comprises a radial recess in which the element is disposed

end of the cable.

  Advantageously, the cable end element is in abutment against a portion of the end piece, at the exit of the cable from the end piece, before the end piece is mounted on the housing. We thus precisely identify the

  relative position of cable and sheath.

  After the end fitting has been mounted on the housing, the cable end element can be enclosed in an enclosed space formed by

  end piece, case and pallet.

  The cable provided with its end, according to the invention, is intended for

  a control device as described above.

  The invention also relates to a method of mounting a control device in which the cable and the end piece are first installed in the vehicle door, then the end piece is fixed on the face

  rear of the housing, and finally the housing is fixed to the door.

  The invention will be better understood and other advantages

  will appear in the detailed description of an embodiment taken from

  title of example in no way limiting and illustrated by the appended drawing, in which: the single figure is a schematic sectional view of the

  control device according to the invention.

  As can be seen in the single figure, the vehicle is equipped with a mechanism for controlling the opening of a vehicle door intended to actuate a lock, not shown. The control mechanism comprises a housing 1 capable of being fixed to the wall of a door not shown, a pallet 2 pivoting about an axis 3 secured to the housing 1, a sheath 4 provided with a nozzle 5 fixed to the housing 1. A cable 6 is placed in the sheath 4 and can slide inside the latter. The end of the cable 6 is provided

  an end element 7 in the shape of a barrel.

  The housing 1 includes a visible side the concave and an opposite side lb not visible after mounting. The pallet 2 comprises a gripping part 2a which extends on the side of the visible face Ila of the housing 1 so that a user can grasp it to rotate the pallet 2. In contrast, the pallet 2a comprises a fork 2b provided with a first lug 8 and a second lug 9, both radial with respect to the axis 3. The radial lugs 8 and 9 define between them a radial housing 10 in which the end element 7 of the

cable 6.

  On its convex face 1b, not visible, the housing 1 comprises a first wall 11 and a second wall 12 parallel to each other, directed towards the rear of the mechanism and arranged with a spacing between them such that the end piece 5 of the cable 6 is disposed between said

walls 11 and 12.

  The nozzle 5 is generally elongated with one end a connecting to the sheath 4 and in contact with the wall 12 of the housing 1

  and an opposite end 5b in contact with the wall 11 of the housing 1.

  The tip 5 comprises, between the end 5a and the end 5b, a curved portion 5c, the curvature of which corresponds to the distance from the axis 3. The curved portion 5c comprises a rib 5d projecting towards the fork 2b from pallet 2. Rib 5d ends

  on the side of the end 5a of the end piece 5 by a stop 5e.

  Before assembling the end piece 5 and the housing 1, the end element 7 of the cable 6 is in contact with the stop 5e. The relative position of the cable 6 and the sheath 4 is thus precisely known and the operating clearance of the mechanism is thus reduced. During assembly, the end piece 5 and the cable 6 are first installed surrounded by the sheath 4 and generally provided with the lock (not shown) disposed at the other end of the cable 6, in the door of the vehicle. Then a subassembly formed from the housing 1 and the pallet 2 is brought in and the endpiece 5 is fixed in the housing 1 by a simple translational movement which causes the snap-fastening tabs, not shown, of the endpiece 5 in windows not shown in the housing 1. At this time, the end element 7 of the cable 5 comes into contact with the lug 9 of the fork 2b and is housed in the housing 10 while no longer being in contact with the stop Se of the end piece 5. The end element 7 of the cable 6 remains in contact with the rib 5d of the end piece 5 and with the lug 9 of the fork 2b. This makes contact between the fork 2 and the end element 7 of the cable 6 by a simple translational movement. Finally, the housing 1 fitted with the end piece 5 is fixed to the vehicle door by means of

  fixing means such as clipping and screwing.

  In operation, the user grasps the gripping part 2a of the pallet 2 and causes it to pivot about the axis 3. The fork 2b also pivots, remaining in the immediate vicinity of the concave portion 5c of the nozzle 5 The lug 9 of the fork 2b can be provided with a groove intended to match the profile of the rib 5d and to let the cable pass through. The lug 9 drives, when it is pivoted, the end element 7 of the cable 6, the sheath 4 remaining fixed and integral with the end piece 5. The end element 7 of the cable 6 is guided radially by the rib 5d. The extreme position of the pallet 2 at the end of its pivoting is shown in phantom on

the single figure.

  Throughout its trajectory, the end element 7 of the cable 5 is enclosed in the housing 10 by the fork 2b and by the rib 5d. More generally, the end element 7 and the portion of the cable 5 protruding following the end element 7 are enclosed in a closed space formed by the housing 1, the pallet 2 and the end piece 5. The end element 7 of the cable 6 is thus difficult to access and the mechanism for controlling the door opening is

  well protected against attempted break-ins.

  It will be noted that the walls 11 and 12 of the convex face 1b of the housing 1 are oblique so as to allow satisfactory movement of the pallet 2 around its axis 3 in the housing 1, while leaving the smallest possible free space 13 between the pallet 2, near the fork 2b, and the wall 12 of the housing 1. This improves the general external appearance and the finish of the control mechanism. Although the walls 11 and 12 are oblique, the end piece 5 is fixed between them by a simple translational movement and perpendicular to the axis of the cable 6 to facilitate the assembly of

the nozzle 5 and the housing 1.

  Thanks to the invention, a mechanism is obtained for controlling the opening of a door, the technical parts of which, i.e. the sheath 4, the end piece 5, the cable 6, the fork 2b, the axis 3 and the rear face 1b of the housing 1 can be standardized while leaving the possibility of modifying the design, that is to say the parts visible by the user, the gripping part 2a of the pallet 2, the face concave 1 of housing

  and the visible space 13 variable in the visual direction.
