Abstract:
1. A runner for a motor vehicle seat, said runner comprising firstly first and second rails mounted to slide relative to each other in a longitudinal direction, and secondly a locking mechanism for preventing said first and second rails from moving relative to each other, the locking mechanism comprising: a longitudinal succession of catches carried by the first rail; a main latch which is provided with a series of teeth and which is connected to the second rail, said main latch being mounted substantially to pivot about a first pivot axis between a locked position in which the series of teeth co-operates with the catches on the first rail so as to prevent the first and second rails from moving relative to each other, and an unlocked position in which the series of teeth does not co-operate with the catches on the first rail so as to enable the first and second rails to move longitudinally relative to each other; and control means comprising a control member that can be moved between a locking position and an unlocking position so as to cause the main latch to pivot from the locked position towards the unlocked position; wherein an additional latch is mounted substantially to pivot on the main latch about a second pivot axis, said additional latch being provided with at least a first series of teeth, and wherein the additional latch is interposed between the main latch and the control member so that, when said control member moves from the locking position to the unlocking position, firstly the additional catch is pivoted about the second pivot axis, and secondly the additional latch and the main latch are pivoted about the first pivot axis.
