Seat assembly with inner seat back movable with a seat cushion

摘要

A seat assembly includes a seat cushion and a seat back. The seat cushion has opposite front and rear ends. The seat cushion is selectively height adjustable relative to the floor of the vehicle. The seat back has nested outer and inner support members. The outer support member has an upper portion extending between spaced apart side bolsters. The inner support member is disposed between the side bolsters and below the upper portion of the outer support member. The inner support member is operatively coupled to the seat cushion for movement therewith relative to the outer support member. The inner support member remains below the upper portion of the outer support member to provide continuous support to the lower portion of the occupant's back during adjustment of the seat cushion relative to the floor of the vehicle.
