Abstract
A bumper system for a motor vehicle includes an energy absorber and a bumper beam interconnecting the energy absorber and vehicle structure. The bumper system also includes a push bar disposed below and operatively connected to the bumper beam to deflect and rotate during an impact with an object by the bumper system.
Claims19
A bumper system for a motor vehicle comprising:
- an energy absorber;
- a bumper beam connected to said energy absorber and connected to vehicle structure at a front end of the motor vehicle;
- a push bar disposed below said bumper beam to deflect and rotate during an impact with an object by said bumper system;
- and
- a spring device connected to said push bar and said bumper beam.
A bumper system for a motor vehicle comprising:
- an energy absorber;
- a bumper beam connected to said energy absorber and for connection to vehicle structure;
- a push bar disposed below said bumper beam to deflect and rotate during an impact with an object by said bumper system;
- a spring device connected to said push bar and either one of said bumper beam and the vehicle structure;
- and
- wherein said spring device has a base wall and side walls extending perpendicularly from said base wall to form a “U” shaped cross section.
A bumper system for a motor vehicle comprising:
- an energy absorber;
- a bumper beam interconnecting said energy absorber and vehicle structure at a front end of the motor vehicle;
- a push bar disposed below said bumper beam to deflect and rotate during an impact with an object by said bumper system;
- said push bar comprising a push bar member made of a relatively rigid material extending laterally across a front of the motor vehicle;
- and
- a spring device connected to said push bar and said bumper beam.
