An air bag comprising: an upper panel (102) and a lower panel (104) both of woven material sewn together forming a generally circular structure and a tether unit or assembly (116, 118a, 118b, 130a, 130b) of the same material as one of the upper and lower panels for controlling the shape of the air bag as same is inflated by inflation gas and for absorbing a shock load created upon inflation. The tether assembly comprises a central portion (116) secured to the upper panel and only two tethers (118a, 188b) extending oppositely therefrom all of integral construction and being of sufficient strength such that each tether can separately withstand the shock load created upon inflation without being damaged. Fabric reinforcements (130a, 130b) are also provided to secure the tethers to the lower panel.
