ABSTRACT:
An energy absorbing apparatus having first and second members (20,28) with a plurality of interlocking projections thereon for resisting motion between the first and second members (20,28). An energy absorber as disclosed may be used in passive restraint systems of motor vehicles (10). Examples are shown with the energy absorbing apparatus integrated in a steering column system (12) and a seat belt system (14). Specifically, the interlocking projections (36) on the first and second surfaces (22,34) of the first and second members (20,28) permit an impact force to be dissipated at a variable rate as the second member 28 is forced past the first member (20).
