Inflatable passenger-size adjustable torso belt system including enclosure mount and method of passenger restraint

摘要

A vehicle passenger restraint system in which a belt band includes a lap belt portion which may or may not be inflatable and an inflatable torso belt portion. The toro belt portion is partially mounted in an enclosure which prevents substantial inflation with the remainder of the torso belt portion positioned to protect the passenger. When a large passenger buckles-up more torso belt is withdrawn from the enclosure. Upon activation of the inflator with a larger passenger buckled-up, gases are supplied to the torso belt portion in the enclosure with less gas remaining in the enclosure and more gas being supplied to the torso belt portion outside the enclosure which portion protects the larger passenger. When a small passenger buckles-up, less gas is supplied the torso belt portion outside the enclosure.
