Abstract
Abstract An occupant restraint cushion includes an internal horizontal wall interconnecting the front and rear walls thereof and subdividing the cushion into upper and lower compartments for respective engagement by the head and torso of the occupant. The horizontal subdividing wall and one or more additional horizontal walls angularly divergent thereto control the curvature of the front wall of the cushion to limit membrane forces applied by such wall to the head of the occupant. The cushion further includes one or more pairs of vertical walls or vertical subdividers which interconnect the horizontal subdividing wall and the front wall of the cushion, through the additional horizontal walls, to subdivide the upper compartment of the cushion into subcompartments which operate independently of each other when engaged by the head of the occupant.
