Patent ID: 7306080

Claim:
A system for absorbing energy from an impact, said system comprising: an energy absorbing member comprising first and second opposing walls; at least one rib disposed between said first and second opposing walls; said energy absorbing member consisting of a thermoplastic polymer alloy having a 15 to 40 kg/cm 2 Izod impact value at an ambient temperature, said thermoplastic polymer alloy consisting of a polyolefin based resin and 50-75% by weight of an amorphous resin which is at least one resin selected from the group of resins consisting of polystyrene resin, impact resistant polystyrene resin, modified polyphenylene ether resin, and mixtures thereof, and said energy absorbing member having the stress change ratio within 15% at the temperature from −15° to 60° C. with respect to the compression distortion at ordinary temperature.
