ABSTRACT:
Disclosed is a selectable position adjusting or setting mechanism for a seat for automotive vehicles using an electric motor with multiple armatures or by using separate motors. Action of the motor is transmitted through respective drives to lead screws to translate the seat horizontally, to raise or lower the front end of the seat and to lower or raise the rear end of the seat. The motor action is transmitted to three parallel lead screws to drive these individual lead screws and result in three types of seat movement. To provide speed for the horizontal movement, a lead screw having a very high lead or pitch is used. In addition, the operative members of the mechanism are mounted compactly providing a comparatively short, low profile design.
