Abstract
A seat height adjustment system particularly adapted for use with vehicle seats and which permits the elevation of one side of the seat base to be adjusted relative to the elevation of an opposite side of that base. The system employs spring assemblies to provide an upwardly directed bias on the seat base which urges that base towards a position of maximum elevation. An actuator is operable to effect downward adjustment of the seat base elevation by imposing a force on the seat base which acts counter to the bias force. Actuator may include two electric motors each of which is connected to a respective two corners of the seat base through flexible drive cables. The arrangement is such that the seat base corners controlled by a respective one of the motors move up or down according to whether the motor is operated in a forward or a reverse mode respectively.
