Seat Track Apparatus

摘要

A seat track apparatus of a vehicle for retaining a slide member between a lower seat track and an upper seat track of the seat track apparatus. The seat track apparatus provides a channel in the lower seat track having at least one longitudinally extending contact surface. The slide member has a shape complementary to the channel and is disposed within the channel with at least one contact surface in contact with the contact surface of the channel. The slide member provides a plurality of cylindrical pins projecting outward from the side wall of the slide member and extending through apertures in the side wall of the lower seat track. The engagement of the pins by the lower seat track aligns and restricts movement of the slide member in the plane in which the cylindrical pins extend therethrough. In a preferred embodiment, the slide member provides outwardly projections on the bottom wall of the slide member. Apertures provided in the bottom wall of the lower seat track receive the projections extending from the bottom wall of the slide member to maintain contact between the contact surface of the slide and the channel. In a second embodiment, the bottom wall of the lower seat track has a plurality of punched lanced upsets which abut the bottom wall of the slide member and prevent the bottom wall of the slide member from moving away from the channel thus maintaining contact between the contact surfaces of the slide member and the channel.
