Abstract
A vehicle seat is disclosed with a seat back frame with a pair of spaced apart linkages connected to side members of the frame. A horizontally actuatable lumbar mechanism is connected to the pair of linkages for providing lumbar support to the occupant and for receiving an input force for actuating the linkages. A head restraint extends from the seat back frame and is operably connected to the frame and the pair of linkages such that actuation of the linkages actuates the head restraint from a design position to an actuated position. A flexible band lumbar support mechanism is provided. Also, a lumbar mechanism is provided with a pair of upright wires and a series of transverse suspension wires for supplying the back of the occupant and for distributing the input force during an impact.
