Abstract

A vehicle seat, which provides an enhanced level of comfort, by means of dual independently supported seat cushions is disclosed. The apparatus comprises an inner seat cushion and an outer seat cushion, each of which is independently supported by a compressed air pneumatic device to control vertical movement, and by parallelogram linkages control lateral movement, and allow for vertical transition of the seats while maintaining them horizontal. The occupant of this vehicle seat can independently adjust the distribution of body weight shared by the inner seat cushion and the outer seat cushion from time to time, in order to change the pressure pattern against body parts and to provide optimum ergonomic seating posture. Furthermore, by adjusting the air supply, the occupant can increase or decrease the seat's effective spring rate, thus controlling the ride height and the seat's compliance for travel on both rough terrain and smooth roadways.
