ABSTRACT:
A safety seatbelt which is designed to be worn slack and which is automatically tightened by expansion of a woven retraction tube disposed within a cover tube acting as the seatbelt. The retraction tube has a weave that causes considerable shortening (minimum 50% of length) when expanded and is attached to the cover tube to cause a corresponding section of a flexible lengthwise contraction of the cover tube and thereby shorten the belt. A self-contained gas generator and collision sensor in a belt latch piece socket direct a gas into a bladder tube within the retraction tube to expand the retraction tube and shorten the belt when a collision of a predetermined severity occurs and thereby cause the belt to be tightened.
