ABSTRACT:
An adjustable automobile seat includes a pair of base members, a pair of carrier members for supporting a load, and support legs intermediate the base and the carrier members. An actuating handle is operative for vertically moving the carrier members relative to the base members to thereby adjust the height position of the seat. The support legs together with additional links form a four bar linkage intermediate the base and carrier members. The four bar linkage is operative for maintaining the torque for turning the actuating handle substantially constant during turning movement of the handle.
