Abstract
A seat assembly for supporting a seat occupant in an automotive vehicle comprising a seat cushion for support the seat occupant on the seat assembly (10) and a seat back (16) extending longitudinally between a lower portion operatively coupled to the seat cushion and an upper portion for supporting the seat occupant in an upright position. The seat back (16) includes an outer peripheral frame member and an inner occupant support frame operatively connected and supported by the outer peripheral frame member and movable from an occupant support position to an impact displacement position extending rearwardly of the outer peripheral frame member. A displaceable connection member operatively interconnects the inner occupant support frame in the occupant support position during normal seat occupant use and for providing movement of the inner occupant support frame to the impact displacement position in response to a predetermined impact load exerted on the seat assembly (10).
