Wrapped inflatable restraint

摘要

An air bag (12) for restraining an occupant (14) of a vehicle (16) has a deflated condition and an inflated condition. The air bag (12) has layers (20, 22) defining between them an inflation fluid volume (18) into which inflation fluid is directed to inflate the air bag. A fluid impermeable wrap (140) encircles the air bag (12) when the air bag is in the deflated condition. The wrap (140) has fluid inlet openings (190, 192) for receiving inflation fluid and for directing inflation fluid into a predetermined portion (120) of the folded air bag (12) to cause the predetermined portion to inflate first.
