An air bag (22) having: an inflatable cushion portion (30) and a neck portion (32) in communication therewith, the neck portion defines a receiving opening to receive inflation gas, received from an inflator, to inflate the cushion portion (30). The air bag is made from flexible material and a retainer member(s) (70a,b; 100) and is preferably sewn to at least a part of the neck portion to reinforce the neck portion and to reduce the flexibility of the neck portion.
