Device and method for absorbing impact energy

Image Number 13 for United States Patent #5351791.

An energy absorbing device comprising: an elongate body arranged along a longitudinal axis to receive an axial impact force at a first end thereof; apparatus arranged adjacent a second end of the body for deformation thereof; die apparatus for producing deformation of the body and a ring fixed to the die apparatus and surrounding the body. Also disclosed is a repeatable energy absorption device including crushing apparatus having threaded apparatus on its outside surface. Upon receipt of the axial impact, the first end of the body moves from a first position away from the crushing apparatus to a second position closer to the crushing apparatus. The device additionally includes threaded sleeve apparatus having a first end for supporting the crushing apparatus and for moving the crushing apparatus toward the first end after the axial impact, to return the first end of the body to the first position.
