Problems solved by technology

In particular, the direction of the controls is reversed when the user uses the device from the trunk, which would cause operational errors and would not improve the ergonomics associated with this function

Embodiment Construction

[0020] Figure 1A A motor vehicle seat 2 is shown comprising a backrest and a cushion frame 6 . The first rail 3 is fixedly mounted to a structure 4, for example the floor of the vehicle. This first rail 3 is mounted directly on the structure of the vehicle by screwing or welding in a conventional manner. Once in place, the first rail 3 receives a second set of rails 5 that can slide longitudinally in the first. The second rail 5 supports the seat 2 and transmits to it the translational movement desired by the user.

[0021] The two sets of rails 3 and 5 are metal parts sliding relative to each other by means of conventional ball bearings. These parts 3 and 5 support the entire frame of the seat 2 and ensure the safety of the occupants in the event of deformation, for example due to a collision.

[0022] The locking mechanism 1 connected to the second rail 5 holds the second rail 5 in position relative to the first rail 3 . As shown in FIG. 1B , the mechanism 1 comprises a...

Abstract

The invention relates to a mechanism (1) for locking the rails of a motor vehicle seat (2) comprising a first rail (3) joined to a structure element (4) along a longitudinal axis of the vehicle, a second rail (5) sliding in the first rail (3) and supporting the seat frame (6) of the seat (2), a first cross-bar (7) pivoting in the second rail (5) along an axis essentially perpendicular to the two rails coaxially held in a desired position relative to one another via a return mechanism (8) of the first cross-bar (7), characterized in that a second cross-bar (9), which comprises a first protuberance (10) oriented toward the front of the seat (2) and a second protuberance (11) oriented toward the rear of the seat (2), is connected to the first cross-bar (7) so that the longitudinal displacement of the seat (2) is controlled by the two protuberances (10, 11).

Description

technical field [0001] The invention relates to a mechanism for locking a seat track of a motor vehicle, in particular a rear sliding seat track of a motor vehicle. Background technique [0002] Motor vehicles are generally fitted with a row of seats located behind, for example, a front driver's seat. This (of the seat) assembly is often in the form of a row of seats separated from each other. In order to meet the needs of the modularization of the vehicle's passenger compartment, each seat is equipped with rails that allow longitudinal movement. The tracks have a locking mechanism that allows them to be held in place or released by tie rods that are exposed under each seat and are accessible by the user from the front of the seat. [0003] Users wishing to adjust the rear seats from the trunk of the vehicle also have means connected to the front tie rods, enabling the seats to be moved towards the front of the vehicle and freeing up the most available space in the trunk. ...
