Vehicle seat adjustment system
First Claim
1. A vehicle seat adjustment mechanism comprising a first member for securing to a seat, and a second member for securing to a vehicle and movable relatively to the first member, one of the members having a pair of closely spaced walls defining between them a substantially enclosed space, and a gear mounted within the enclosed space to turn about an axis transverse to the length of the members for effecting adjustment of the mechanism.

Abstract
At each side of the seat is a slide mounting assembly consisting of a fixed slide (12) and a moveable slide 22 which carries independent means for controlling fore-aft sliding, front height adjustment, and rear height adjustment. That may be by electric motors (3, 5, 7) or by mechanical means controlled by a lever (107). Driving gear (FIG. 3) is mounted in the enclosed space between the walls (24) of the moveable slide and includes epicyclic gearing which in an electrical embodiment, is driven through a worm (32) and worm wheel (34). Racks (40, 56, 76) are used for effecting or controlling the adjustment and are mounted within the enclosed space. A mechanical version (FIG. 10) and an electrical version (FIG. 7) are interchangeable.

9. A pair of vehicle seat adjustment mechanisms, one for each side of the seat, each including first and second relatively adjustable members, having respective means for connection to a seat and a vehicle body, each mechanism having a drive input for effecting adjustment of one member in relation to the other, including also an electric motor having two drive outputs at opposite ends of a motor shaft, each drive output being connected to the drive input of a different one of the adjustment mechanisms.
- 10. A fore-aft vehicle seat adjustment mechanism including first and second slides which cooperate in sliding relationship, one slide comprising a base, and the other slide comprising side walls, a rack gear constituted by a series of apertures extending along the base of the one side, and a pinion mounted for rotation between the side walls of the other slide, the pinion having teeth meshing with the rack gear for effecting fore-aft adjustment.
