ABSTRACT:
The specification discloses an energy absorbing structure having a rod-like lateral cross section such as a hand rail, steering wheel or the like in which an inner structural member is made of a material capable of providing rigid structural strength, but being frangible upon sharp impact of the type encountered in vehicle accidents so as to absorb energy from the impact, and an exterior covering generally surrounding the inner member and being made of a somewhat stretchable, flexible, tough skinned and nonabrasive plastic material of sufficient thickness and strength that in the event the inner member does break, the covering prevents sharp ends or edges of the broken inner member from protruding and impaling an individual impacting the structure.
