Abstract
Abstract A method and apparatus for preparing a moving vehicle for impending impact with another vehicle or object which incorporates the extending of the air bag to fill in the space between an extendible bumper. A detection apparatus senses a dangerous speed of the vehicle or an approaching object in the path of the vehicle and extends the bumper forwardly or rearwardly from the body of the vehicle while at the same time filling the space between the body and bumper with an inflated air bag. Should the impact not take place, or the dangers facing the vehicle have decreased, the apparatus retracts to its initial inoperative condition. One form incorporates a first filled bag which is filled at all times, and then a second bag which is inflated when the bumper is extended. A modified form moves an elongated bag into position with its longer dimension filling the space between the body of the vehicle and the bumper, and correspondingly returns the bag so that its shorter dimension fits in between the retracted bumper and the body of the vehicle.

261 words
The method of intercepting an object in the path of a passenger vehicle during impact between said object and passenger vehicle while said vehicle is traveling at a predetermined unsafe impact speed which comprises: a. Providing a detection means on said moving vehicle that anticipates a possible impending impact with an object in the path of said moving vehicle or an object coming upon said vehicle from behind; b. Inserting a forwardly or rearwardly extending mechanism within the frame of said vehicle for actuating an extension procedure of the bumpers of said vehicle prior to an impending impact of said vehicle as determind by said detection means; c. Providing a releasable retaining apparatus for keeping said extending mechanism either from being actuated from an initial retracted condition or for keeping said retaining apparatus in an extended condition when it has been moved into that position while preparing for possible impending impact with another object; d. Placing a dually compartmented impact shock absorbing air cusioning apparatus at either front or back, or both, of said moving vehicle between said frame of said vehicle and the bumpers of said vehicle; e.
