Patent number: 7766424Abstract: A recliner mechanism for a vehicle seat includes a support plate (7) mounted on the squab (2) of the seat, and a support plate (11) mounted on the back rest (3) of the seat. There is a pivotal interconnection (10) between the plates to enable the back rest to be reclined. The pivotal interconnection is initially retained by a spring (20), in a retaining part (15) of an elongate slot (14). When the back rest (3) is subjected to a rearward force, such as by a seat occupant in a rear impact situation, the spring is deformed and the pivot shaft moves along the slot (14), enabling the back rest (3) to move rearwardly. An energy absorbing element (17) is provided which deforms, whilst absorbing energy, during this second movement of the back rest.Type: GrantFiled: September 28, 2005Date of Patent: August 3, 2010Assignee: Autoliv Development ABInventor: Lennart Haglund

Publication number: 20100173137Abstract: Markings visible by automatic optically guided cutting equipment are provided in a fabric such as a double layer fabric for one-piece-woven air bags by groups of black marker weft yarns which contrast with the other (white) weft yarns and warp yarns. The marker weft yarns emerge onto the upper face of the fabric only in predetermined marker areas spaced apart in the warp direction by other white weft yarns to afford optically identifiable markings spaced apart along said weft yarns and spaced apart along the direction of the warp yarns. The arrangement avoids the need for black warp yarns and thus avoids the inconveniences and loom down-time associated with required alterations to the locations of such optically detectable marker areas in the fabric web.Type: ApplicationFiled: May 24, 2007Publication date: July 8, 2010Applicant: AUTOLIV DEVELOPMENT ABInventors: Altay Kismir, Willhelm Heinrichs, Brian Parry, Keri Kennedy, Kevin Smith

Patent number: 7735859Abstract: A safety arrangement to provide protection for an occupant in a motor vehicle includes a seat-belt provided with a measuring device to measure energy absorbed by the seat-belt. The measuring device may determine the length of safety-belt paid-out after a retractor locks, the belt being paid-out against a force provided by a force-limiter. The energy absorbed is calculated and is used to control the vents of a ventable air-bag. The air-bag is vented if a substantial part of the energy of the occupant is absorbed by the seat-belt, but is not vented if a large proportion of the energy has not been absorbed by the seat-belt.Type: GrantFiled: July 1, 2005Date of Patent: June 15, 2010Assignee: Autoliv Development ABInventors: Anders Lenning, Mikael Dahlgren
