Abstract

A control system for locking devices for vehicle seats comprising a chassis and an element mobile along a straight direction relative to the chassis and a first pivoting arm. A first end of the first pivoting arm is fixed to the mobile element of the linear actuator. A second end of the first pivoting arm is adapted to push, respectively pull, a first pin of a first locking device when the mobile element of the linear actuator is moved relative to the chassis, in order to control locking or unlocking of the first locking device.

First claim

1 . A control system for locking devices for vehicle seats where the control system comprises:
a linear actuator comprising a chassis and an element mobile along a straight direction relative to the chassis; and a first pivoting arm, where a first end of the first pivoting arm is connected to the mobile element of the linear actuator, and a second end of the first pivoting arm is adapted to push, respectively pull, a first pin of a first locking device when the mobile element of the linear actuator is moved relative to the chassis, in order to control locking or unlocking of the first locking device.

2 . The control system of claim 1 , wherein the first end of the first pivoting arm is fixed to the mobile element.

3 . The control system of claim 1 , further comprising a first connecting rod mounted pivoting relative to the first end of the first pivoting arm, on a one side, and to an end of the mobile element, on the other side.

4 . The control system of claim 1 , comprising a second pivoting arm, where a first end of the second pivoting arm is connected to one among the chassis of the linear actuator and a second element mobile along the straight direction relative to the chassis, and a second end of the second pivoting arm is adapted to push, respectively pull, a second pin of a second locking device when at least one among the mobile element and the second mobile element is moved relative to the chassis, in order to control locking or unlocking of the second locking device.

5 . The control system of claim 4 , wherein the first end of the second pivoting arm is connected to one among the chassis of the linear actuator and a second element mobile along the straight direction relative to the chassis.

6 . The control system of claim 4 , comprising a second connecting rod mounted pivoting both relative to the first end of the second pivoting arm and relative to one among the chassis of the linear actuator and a second element mobile along the straight direction relative to the chassis.

7 . The control system of claim 4 , wherein the first and second pivoting arms are each arranged on one respective side of the linear actuator.

8 . The control system of claim 1 , further comprising means of control of the linear actuator.

9 . The control system of claim 8 , wherein the control means of the linear actuator comprise a button.

10 . The control system of claim 8 , wherein the control means of the linear actuator comprise a position sensor.

11 . A track mechanism for a vehicle seat comprising:
a first track comprising a first rail mobile relative to a first fixed rail; a second track comprising a second rail mobile relative to a second fixed rail; a first locking device for the translation of the first mobile rail relative to the first fixed rail, where the first locking device comprises a first pin controlling a locking or unlocking of the first locking device; a second locking device for the translation of the second mobile rail relative to the second fixed rail, where the second locking device comprises a second pin controlling a locking or unlocking of the second locking device; a control system according to claim 4 , where the control system is suited for moving the first and second pivoting arms so that the second end of the first pivoting arm pushes, respectively pulls, the first pin of the first locking device in order to control locking or unlocking of the first locking device and the second end of the second pivoting arm pushes, respectively pulls, the second pin of the second locking device in order to control locking or unlocking of the second locking device.

12 . The track mechanism of claim 11 , comprising at least one among a first play between the second end of the first pivoting arm and the first pin of the first locking device and a second play between the second end of the second pivoting arm and the second pin of the second locking device.

13 . The track mechanism of claim 12 , where at least one among the first play and the second play is between 1 mm and 2 mm.

14 . The track mechanism of claim 11 , wherein the first track and the second track extend parallel to a longitudinal direction of the tracks, where the straight direction along which the mobile element of the linear actuator is mobile is perpendicular to the longitudinal direction of the tracks.

15 . The track mechanism of claim 14 , wherein the first pivoting arm is mounted pivoting around a first axis of rotation, where the first axis of rotation is parallel to the longitudinal direction of the tracks.

16 . The track mechanism of claim 14 , wherein the second pivoting arm is mounted pivoting around a second axis of rotation, where the second axis of rotation is parallel to the longitudinal direction of the tracks.

17 . A vehicle seat assembly comprising an automotive vehicle seat with a vehicle seat bottom and a track mechanism according to claim 11 , where the seat bottom of the vehicle seat is fixed to the first and second mobile rails.

18 . The vehicle seat assembly of claim 17 , wherein the first pivoting arm is mounted pivoting around a first axis of rotation, where the first end and/or the second end of the first pivoting arm is arranged vertically below the first axis of rotation.

19 . The vehicle seat assembly of claim 17 , wherein the second pivoting arm is mounted pivoting around a second axis of rotation, where the first end and/or the second end of the second pivoting arm is arranged vertically below the second axis of rotation.
