ABSTRACT:
A vehicle bumper includes an elongated shell member for attachment to an end portion of a vehicle. An impact member is received within the shell member for limited lateral sliding movement and is biased outwardly through an elongated opening in the shell member. A coil spring biases the impact member outwardly from the shell member and a shock absorber dampens lateral movement of the impact member. An air bag is received in an outwardly opening elongated cavity in the impact member and is inflatable upon a severe impact. A resilient cover which surrounds the impact member and encloses the air bag includes a pair of inwardly extending elongated ribs in frictional engagement with a pair of parallel grooves provided in an outer portion of the impact member. The cover has a padded outer portion for absorbing minor impacts and is released from engagement with the impact member upon inflation of the air bag. An air spoiler may be secured to the shell member.
