Abstract: A power seat adjuster includes a drive link fixed to a torsion tube rotatably supported between the upper tracks of a pair of track assemblies. One end of the drive link is pivotally connected to a first leg depending from an upper seat support frame member. First and second flanges respectively formed on the first end of the drive link and the first leg lie in an intersecting path for engagement upon rotation of the first end of the drive link beyond a normal end travel position to resist continued rotation of the first end of the drive link and the upper seat support frame. Similar cooperating flanges are formed on a slave drive link and on the lost motion strut of a rear elevating mechanism.

Abstract: 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.
