| 摘要 |
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).
