Vehicle seat slide mechanism
First Claim
1. A vehicle seat slide mechanism comprising two seat slides, each consisting of an upper rail adapted to carry the vehicle seat and a lower rail associated therewith and adapted to be connected to the vehicle floor, each upper rail being capable of movement in a fore-and-aft direction relative to the associated lower rail, a trigger mounted on at least one upper rail and normally urged by biasing means into a locked position in engagement with at least one of a series of apertures or notches in the associated lower rail to prevent relative movement of the upper rail with respect to the lower rail, a release member cooperating with the trigger and arranged to move the trigger from the locked position to an unlocked position out of engagement with the at least one aperture or notch in the lower rail, a memory member carried by the lower rail of one of the two slides and movable parallel thereto by engagement with an engagement member carried by the upper rail of the same slide, a latch operable to disengage the engagement member from the memory member and to move the trigger out of engagement with the associated lower rail to allow forward movement of the upper rail and seat thereon, the memory member remaining in position on the lower rail characterized in that the upper rail is provided with a pawl which holds the engagement member in the position where the trigger is disengaged from the lower rail while the upper rail is moved forwardly and the memory member comprises a front surface, a ramp surface and a slot engageable by the engagement member in the form of a pin, whereby on rearward movement of the upper rail, the pawl engages the front surface and releases the pin which is moved along the ramp surface and into the slot.
