ABSTRACT:
A cushion to provide added impact resistance to front or back bumpers of passenger cars or light trucks. The cushion may be bolted to front or back standard bumpers and consists of two steel plates or rails about 4" wide, and 1/4" thick separated by some 3". It may also be chrome plated for aesthetic reasons. The same rail is bolted to each respective bumper and the interspace between the rails includes steel coil springs approximately 4" apart, welded to and separating the two rails. Each spring is encapsulated with a heat resistant tape wrapping and the space outside the springs and between the rails is filled with shock-absorbing rubber or plastic material. The interior of each spring is accordingly free of the shock-absorbing material and can function as a coil spring without the inhibition of the resilient filling material.
