摘要

A passenger restraint system (100) for an occupant of a vehicle (102) includes an inflatable belt portion comprising a seamless hollow inflatable textile member that becomes inflated upon the occurrence of a collision. The inflatable textile member may vary in size and construction along its length. The belt portion (104, 112) tightens against the occupant's body when the inflatable belt portion becomes inflated.
