ABSTRACT:
A blow molded vehicle seat frame system with integral restraint safety belt comprises a blow molded full bench, split bench or high back seat frame with discrete, strategically-placed, insert tubular beams to provide seat and seat belt mounting and load carrying capacity. A molded back contains tubular side cavities housing non-circular reinforcing beams therein. A telescoping tube at the top of the beam provides a shoulder belt height adjustment mechanism. The reinforcement beams provide an efficiently designed load path wherein the belt forces resulting from a crash situation are directed through super-high strength roll form metal tubular beams directly to the vehicle seat track or pedestal mounts. The primary load carrying seat component members are designed structurally to create discrete displacement occupant energy absorption to provide safe occupant crash kinematics and deceleration forces. The relative location and design of the load carrying members are arranged to create an efficient light weight structure and permit use of a low modulus, light weight blow molded seat cushion and back in the seat frame structure.
