Patent number: 7318602Abstract: Enhanced airbag modules and associated methods are provided. An airbag module according to the invention may have a cushion with an inflatable protection zone and a flexible venting tube coupled to the inflatable protection zone. A closure mechanism may be used to compress the flexible venting tube against an anchoring member, such as a housing of the airbag module or a vehicle feature, until venting through the flexible venting tube is needed. The closure mechanism may then be actuated, for example, by igniting a pyrotechnic within a specially designed bolt of the closure mechanism. The bolt may, for example, have a bore with a pyrotechnic initiator molded-in-place within the bore. The bolt may fracture to open the closure mechanism, thereby permitting inflation gas to flow out of the inflatable protection zone via the flexible venting tube.Type: GrantFiled: March 13, 2006Date of Patent: January 15, 2008Assignee: Autoliv ASP, Inc.Inventors: Timothy A.
