Energy absorbing pocket member

An energy absorbing assembly for a motor vehicle comprising:

• pair of rails extending longitudinally and spaced laterally;
• a bumper extending laterally across one end of said rails;
• and
• a separate energy absorbing pocket member disposed between each of said rails and said bumper and having a cavity to allow said energy absorbing pocket member to crush and absorb energy of an impact on the bumper, each said energy absorbing pocket member being generally cylindrical in shape and having a closed end disposed adjacent the bumper and an open end disposed adjacent said rails and having a plurality of undulations spaced axially between said open end and said closed end and forming said cavity and being made of a plastic material.

• and
• wherein said energy absorbing pocket member has an axial length greater than a radial width thereof.

An energy absorbing assembly for a motor vehicle comprising:

• a pair of front rails extending longitudinally and spaced laterally;
• a front bumper extending laterally across one end of said front rails;
• and
• an energy absorbing pocket member disposed between each of said front rails and said front bumper, said energy absorbing pocket member extending axially and having a closed end disposed adjacent said front bumper and an open end disposed adjacent one of said rails and a plurality of undulations spaced axially between said closed end and said open end and forming a cavity to allow said energy absorbing pocket member to crush and absorb energy of an impact on said bumper, said closed end having a traverse width less than a traverse width of said open end, said undulations having a radial thickness greater than a radial thickness of said energy absorbing pocket member between said undulations, and said energy absorbing pocket member being made of a plastic material and having an axial length greater than a radial width thereof.
