ABSTRACT:
An improved collision impact absorber for mounting upon a vehicle is formed of an elongated structural member both pivotally and longitudinally movable with respect to the vehicle. Impact force upon the outer end of the structural member is initially absorbed by longitudinal deflection of the structural member, and further absorbed by the rotation of the structural member with respect to the vehicle. The rotation of the structural member with respect to the vehicle transfers and dissipates the impact force into a reactive lifting of the vehicle, the weight of the vehicle acting as a resistant force to the lifting of the vehicle. A catch, or detent, allows the elongated structural member to longitudinally move or deflect a certain, predetermined distance prior to initiating rotation of the member about a pivot point. This prevents rotation of the elongated structural member until after such elongated structural member has undergone a certain predetermined deflection, which translates into a predetermined amount of impact force to initiate dissipation of force by lifting of the vehicle body.
