ABSTRACT:
A front end construction for an automobile body having an essentially rigid, forward mounting structure, the front end construction including a bumper yieldably mounted on a fixed, lightweight, crushable and collapsible supporting frame disposed ahead of the engine compartment of the vehicle and containing a normally folded air-bag, the bumper being adapted to absorb relatively light rearwardly directed impact forces without effect on the supporting frame or the air-bag, the supporting frame being adapted to crush under relatively heavier impact forces sufficient to overwhelm the impact resistance capability of the bumper, and the air-bag adapted to explode under the heavier impact forces referred to which are greater than that required to at least initiate crushing of the supporting frame but less than that required to completely collapse it.
