Patent number: 8851522Abstract: A seatbelt anchor assembly includes a ferrule, a cable, and seatbelt buckle. The ferrule can be mounted at one end to a seat base or other mounted structure of the vehicle, and can further include an anti-rotation pin that is received in a locating hole of the seat base to limit rotation of the ferrule during mounting and during normal occupant use. The pin can be made from aluminum or other material that can shear off in response to a dynamic vehicle load, allowing the ferrule to pivot about its mounting location to align the loads. The ferrule can be in the form of a blank including a body portion and a head portion having a pair of ears, and can include a recess between the ear portions and the body portion to limit tension in the ferrule when the ferrule is crimped to mount a cable thereto.Type: GrantFiled: March 14, 2013Date of Patent: October 7, 2014Assignee: Autoliv ASP, Inc.Inventors: David Srugis, Thomas Garvey, Nick Paglia, David Dziuda, Scott Bellman

Publication number: 20140261729Abstract: An airbag assembly may include an airbag and an inflator in fluid communication with the airbag. The inflator may have a first chamber containing a first gas source and a second chamber containing a second gas source. A filter module may be positioned to filter and redirect gas flows from the first and second gas sources.
