Abstract
A bumper comprises a hat beam (11) adapted to have its crown directed towards the vehicle body, a cover (20) attached to the side flanges (17, 18) of the hat beam and having a longitudinal recess (21) that extends into the hat beam, and an energy absorbing foamed body (22) that fills out the recess and extends with its major part out of the recess. If the foamed body widens out over the side flanges (17, 18) of the hat beam, these widened parts (25) should have recesses (31) that prevent these parts from being fully compacted before the part therebetween is compacted if the bumper hits a pedestrian's leg. A closed cross-section beam having a longitudinal recess can also be employed in the present invention.
Claims22
A bumper for a vehicle, said bumper comprising a beam defining a longitudinal recess, said beam oriented so that said longitudinal recess faces outwardly of said vehicle body;
- an energy absorbing material received, at least in part, in said longitudinal recess, and oriented relative to said longitudinal recess such that a portion of said energy absorbing material extends beyond said beam in a direction outwardly from said vehicle body;
- the portion of said energy absorbing material received in said longitudinal recess and the portion of said energy absorbing material extending beyond said beam and disposed over said longitudinal recess being formed as a unitary solid body.
A bumper for a vehicle, said bumper comprising a beam defining a longitudinal recess and having opposed sides extending respectively from opposed sides of said longitudinal recess, said bumper being oriented relative to said vehicle so that said longitudinal recess faces outwardly of said vehicle body;
- a compressible energy absorbing material received, at least in part, in said longitudinal recess and oriented such that a part of said energy absorbing material extends beyond said beam in a direction outwardly from said vehicle body, a portion of said extending part of said energy absorbing material also extending over said opposed sides of said beam;
- said portion of said energy absorbing material extending over said opposed sides of said beam defining at least one recess therein for reducing the difference in compactness of said energy absorbing material disposed over said longitudinal recess in said beam and said energy absorbing material disposed over said opposed sides of said beam to less than 15% when any portion of said energy absorbing material is fully compressed.
