Description

External opening controller of motor vehicle openable part and motor vehicle with same

Technical Field

The present invention relates to the field of motor vehicles, and more particularly to the field of external opening controls for openable parts of motor vehicles.

Background

The lateral crash standard requires that the vehicle openable member's external opening controller handle remain closed in the event of such a crash.

Published patent document WO 2014/055902 a1 discloses an external opening control for a motor vehicle openable member, which includes an inertia lock system for inertia locking in the event of a side impact on the openable member. The system includes an inertial element associated with the mounting frame of the handle. The inertia element has a center of gravity offset with respect to its rotational axis, and is configured to pivot between a rest position that allows opening of the openable member and a lock position for locking the openable member in the event of a side collision.

Published patent document EP 1766164B 1 discloses an external opening control for a motor vehicle comprising a hinged handle with a swinging wheel. The controller includes an inertia locking system for inertia locking the openable member in the event of a side impact. The system includes a rocker arm provided with an inertial element, the rocker arm being configured to pivot from a rest position to an activated position in the event of a side impact, in which the rocker arm prevents opening of an external control. The rocker arm includes a protrusion and a stop. In the event of a crash, the rocker arm loses balance and the stop blocks the shoulder of the wheel to lock the wheel while preventing pivoting of the handle. Similarly, when pivoted to the activated position, the projection hooks into the aperture of the latch tab, thereby holding the rocker arm in the activated position. Thus, the external opening control is locked.

When the external opening control is installed, the inertial element can be manually touched and switched to the active position by the installation operator, causing the activation of the locking system. The external opening control is no longer operable and therefore needs to be unlocked, which increases the time to install the opening control.

Disclosure of Invention

The present invention aims to overcome at least one of the above-mentioned drawbacks of the prior art. More particularly, the present invention aims to provide an external opening control which allows to avoid manual activation of the locking system during the installation of the control. The invention also aims to provide a simple, economical and stable solution.

The invention relates to an external opening controller of an openable piece of a motor vehicle, which comprises a support piece; a handle mounted on the support, the handle being adapted to pivot in an opening direction to control the lock of the openable member to open the openable member; a locking system mounted on the support, the locking system having a movable inertia element adapted to move from a rest position to a locking position in the event of the opening control being subjected to an acceleration, so as to prevent control of the lock by the handle during the inertia element being in the locking position; it is worth noting that the opening controller comprises a protective barrier of the movable inertial element, located on a side of the element opposite to the opening direction of the handle, which protects the element from the operation of the operator who mounts the controller on the openable member.

Advantageously, the barrier is configured to prevent objects having a size greater than 15mm, preferably greater than 10mm, from passing facing the movable inertial element.

According to an advantageous embodiment of the invention, the support extends along a main plane and the barrier extends parallel to this plane along the movable inertia element.

According to an advantageous embodiment of the invention, the locking system comprises an automatic retaining device for retaining the movable inertia element in its locking position.

According to an advantageous embodiment of the invention, the automatic retaining means comprise an elastic tongue and a projection on the movable inertia element, which is adapted to deform the tongue and to abut an edge of the tongue.

According to an advantageous embodiment of the invention, the tongue has a main direction which is subject to bending during deformation of the tongue. The protective barrier extends transversely to this direction. The bending thus takes place transversely to the main plane of the tongue before it is deformed.

According to an advantageous embodiment of the invention, the protective barrier is formed by an elastic tongue.

According to an advantageous embodiment of the invention, the protective barrier is formed by a plate which is in register with the tongue and is fastened to the support.

According to an advantageous embodiment of the invention, the controller comprises an arm pivotally mounted on the support, cooperating with a handle to be actuated by the handle and comprising a fastening area for fastening a connection line for controlling the lock, the movable inertial element of the locking system being configured to cooperate directly with the arm when locking the lock controller.

According to an advantageous embodiment of the invention, the plate forming the protective barrier supports the end of the pivot of the arm, which is pivotally mounted on the support.

The invention also relates to a motor vehicle comprising at least one openable element with an external opening control, which external opening control is noteworthy in accordance with the invention.

The invention is characterized in that it proposes an external opening control of an openable piece comprising a protective barrier of an inertial element. The protective barrier allows the opening control to be mounted on the openable member without the risk of touching the inertial element. Thus, the protective barrier allows to prevent manual activation of the locking system and to avoid modification of the installation of the controller. The protective barrier also allows to stiffen the support and to avoid the phenomenon of bending of the support, which could lead to opening the openable member.

Detailed Description

Fig. 1 shows an external opening control 2 of a motor vehicle openable member according to a first embodiment of the present invention. The external opening control 2 is shown inside the openable member. The controller 2 includes a support 6 for fixing behind an outer surface of the openable member. The support 6 extends along a main plane that is substantially parallel to the general plane of the openable member. The opening controller 2 further includes a handle movably mounted on the support 6 on the outside of the openable member. The handle, formed by an extension of the support 6, is not shown, only the seat 8 of the handle being shown. The handle is pivotable from a rest position in a direction to open the openable member to control the lock of the openable member to open the openable member. The direction of opening the openable member is toward the rear of the plane of fig. 1. The lock is not shown. The handle is mounted on a handle support 10, which handle support 10 is provided on the control support on the inside of the openable piece. The handle support 10 may be connected to a resilient return element 12, such as a torsion spring, to return the handle to the rest position.

The opening control 2 comprises an arm 14, which arm 14 is pivotably mounted on the support 6 and cooperates with the handle, more specifically with the handle support 10. An arm 14 pivotally mounted on the support 6 cooperates with the handle support 10 to be moved by the handle and in particular with an element 15 of the handle support. The pivotally mounted arm 14 comprises a fastening area 16 for fastening a connecting line 33 (shown in fig. 2 and 3), which connecting line 33 is connected to an openable lock. The pivotally mounted arm 14 is configured to pivot in an unlocking direction d from a rest position in which the arm 14 does not pull the connecting wire 33 to disable the lock so as not to open the openable member, and an unlocking direction d in which the arm 14 pulls the connecting wire 33 to unlock the lock so as to allow the openable member to be opened.

The external opening control 2 comprises a locking system 18 mounted on the support.

Fig. 2 and 3 show detailed views of the controller 2 of fig. 1. In fig. 2, the locking system 18 is in the rest position, while in fig. 3, the locking system 18 is in the locked position. The locking system 18 comprises a movable inertia element 20 adapted to move from a rest position to a locking position in case of an acceleration of the controller 2, to lock the lock controller. For example, if the openable member is a vehicle side door, acceleration of the controller 2 is caused by displacement of the vehicle and deformation of the door receiving the collision during a side collision of the vehicle. The inertia element 20 is also referred to as a weight. The inertia element 20 is configured to directly engage the pivotally mounted arm 14 when the lock controller is locked. More particularly, the inertia element 20 may include a stop surface 22. When the inertia element 20 is pivoted to the locked position, the stop surface 22 comes into contact with the end 24 of the pivotally mounted arm 14 and thus prevents the arm 14 from pivoting in the unlocking direction of the lock. Thus, the external opening controller 2 is locked. The locking system 18 comprises automatic retaining means 26 for retaining the inertial element in the locked position. The automatic retaining means 26 may comprise a resilient tongue 28 and a projection 30 on the inertial element 20, which projection 30 is adapted to deform the tongue 28 during the rest position of the inertial element 20 and to abut an edge of the tongue 28 during the locking position of the inertial element 20. In the locked position, the inertia element 20 can no longer pivot and can no longer return to the rest position, since the inertia element 20 remains locked by the projection 30 abutting against the edge of the tongue 28. During deformation of the tongue 28, the tongue 28 has a main direction which undergoes bending. The tongue 28 extends transversely along a portion of the inertial member 20. The tongue 28 may be fastened to the support 6 or made integral with the support 6. When the opening controller 2 is mounted on the vehicle, the external opening controller 2 can no longer actuate the lock if the mounting operator contacts the movable inertia element 20 in the rest position and pivots it to the locking position. Therefore, the opening controller 2 is no longer operable.

To avoid this problem when installing the external opening control 2, the external opening control 2 comprises a protective barrier 32 for protecting the movable inertial element 20. The protective barrier 32 is shown in a transparent manner in fig. 2 and 3 to facilitate understanding of the latch system 18. The protective barrier 32 protects the inertial member 20 from manipulation by an operator who mounts the controller on an openable member. The protective barrier 32 is located on the side of the movable inertial member 20 opposite to the opening direction of the handle. The protective barrier 32 extends along the movable inertial element 20 parallel to the plane of the support 6 and transversely to the main direction of the tongue 28 facing the inertial element 28. The protective barrier 32 is thus formed by the resilient tongue 28.

Fig. 4 shows a front view of an external opening control 102 of a motor vehicle openable member according to a second embodiment of the present invention. Fig. 4 shows the numbering of the preceding figures for the same or similar elements, however the numbering is increased by 100. Further, reference is made to the description of these elements relating to the first embodiment. Specific numbers are used for specific elements of this embodiment.

According to this second embodiment, the protective barrier 132 of the inertial element 120 is formed by a plate which is adjacent to the tongue 128 and is fastened to the support 106. The plates forming the protective barrier 132 may be made integral with the support 106 or fastened to the support 106. The plate forming the protective barrier 132 supports the end of the pivot 134 of the arm 114, which arm 114 is pivotally mounted on the support 106. More particularly, the plate includes an extension 136, the extension 136 covering the arm 114 and supporting the end of the pivot 134 of the arm, which is pivotally mounted on the support.

Advantageously, the plates forming the protective barrier 132 are perforated and form ribs. The orifice has a major dimension or average diameter of less than 10mm to prevent entry of the fingers of the installation operator.

The

protective barriers

32, 132 of the inertial element 20, 120 of both embodiments also have the advantage of stiffening the support, allowing to limit the bending phenomena of the support, which can lead to the opening of the openable piece.
