Abstract

An apparatus (20) controls the position of an occupant (32) in a vehicle passenger compartment by sensing physical characteristics of the occupant such as weight, height, girth, and leg length. A controller (36) controls seat motors (92, 94, 96) to move the occupant (32) to a position based on the sensed physical characteristics of the occupant. The occupant (32) can override the system using override controls (98). The controller (36) also adjusts the performance of an occupant restraint (22) in response to a selected occupant position.
