Abstract
A method and system for estimating the weight of a seat occupant. In one embodiment, the system includes a linkage having one or more links; an actuator; a pivot driveably coupled between the links and the actuator; and a sensor coupled to the pivot and operable to sense a load at the pivot, where the sensed signal is processed to provide an output signal representative of seat occupant weight. The system provides weight estimation with reduced sensitivity to horizontal loads and may be implemented with seats having a fixed height or a plurality of powered and manual seat height adjustment mechanisms.
