An impact absorber is disclosed herein having a single or a pair of box-beam inflatable members arranged in guided sliding relationship. Elongated slots and shear bolts cooperate to releasably couple the inflatable members together so as to absorb shock prior to shearing. A resilient inflatable block is carried on the forward terminating end of one beam member while a resilient pad is carried on the terminating end of the other beam member in alignment to interfere with the sliding movement of the first member. The various impact-absorbing elements are arranged in a series for sequential actuation upon application of an impact. The inflatable block absorbs shock first, followed by the shear bolts and finally the resilient pad.
