Abstract

A passive passenger restraint is provided which includes a self-supporting deformable U-shaped restraining bar having a pair of parallel connecting arms that extend forwardly and are supported by hinges at their forward ends with a lap bar joining their rearward ends. The lap bar extends between the rear ends of the arms so that upon impact a portion of the energy is absorbed as the lap bar bends the rear ends of the connecting arms. To assist in holding the bar assembly in place, a flexible restaining strap is provided to extend over and encircle the upper aspect of the arms. The ends of the strap are held securely in place on either side of the seat on which the passengers are seated. The strap is able to slide across the upper surface of the arms to that upon impact the tension in the strap bends the arms towards one another as their upper ends bend forwardly.
