An air bag whose envelope is a front panel and a rear panel joined around a common periphery and having a tether having one edge joined to an inside surface of the front panel and another edge joined to the inside surface of the rear surface near the entry port. The tether has two members, an elastic member that is shorter than an inelastic member in its unstretched state. The elastic member controls the rate of inflation of the air cushion thereby lessening the chance of injury due to the sudden inflation of the air bag. The inelastic member controls the shape of the air cushion to accommodate the face and head of the passenger.

1. An inflatable air bag attachable to an inflater for deployment in an automobile for the protection of passengers, said bag comprising:an inflatable envelope having an entry port for admitting gas. a tether means inside said envelope for controlling expansion of said envelope having an elastic member and an inelastic member; said elastic member and inelastic member having a common end secured to an inside surface of said envelope in one area and another common end secured to said inside surface of said envelope in another area; said elastic member having a length that is shorter than a length of said inelastic member providing that when said air bag is deflated, both said inelastic and elastic members are unextended, and when gas initially enters said bag, said elastic member first extends until said elastic member is fully extended, and, as said bag continues to inflate, said elastic member stretches and said inelastic member extends until said inelastic member is fully extended whereby said one area of said bag ceases to unfold while areas of said air bag distal from said another area continue to unfold providing that a concavity is formed in said envelope.
