ABSTRACT:
A lock plate having a plurality of latch holes is connected to a stationary lower rail to extend along the same, and a latch member having latch pawls is fixed to a control rod which is rotatably held by a movable upper rail. One of the latch pawls is longer than the other, so that when the upper rail is slid to a front or rear over-travel position relative to the lower rail, the longer latch pawl is placed outside of an extreme end of the lock plate having the other shorter latch pawl placed on a land portion of the lock plate. Upon application of shock to the upper rail due to for example rapid start or rapid braking of the vehicle, the longer pawl is brought into contact with the extreme end of the lock plate faclitating latched engagement between the shorter pawl and an adjacent latch hole of the lock plate.
