Abstract
An abrasion resistant air bag comprises an outer tubular liner board member having a pair of parallel ply sections defining an internal space therebetween, and an inflatable bladder disposed internally thereof. In order to close and seal the opposite open ends of the outer tubular liner board member, and thereby form the abrasion resistant air bag, a pair of liner board end cap members are adhesively bonded upon the opposite open ends of the outer tubular liner board member. The end caps are formed from initially flat, scored pieces of liner board which are folded in half upon themselves whereupon each leg member or half-section of the end cap is adhesively bonded to an outer surface portion of a respective one of the outer tubular liner board ply sections.
