Patent number: 7717459Abstract: An air-bag arrangement for a motor vehicle is disclosed to provide protection for the occupants (1, 2) of two adjacent seats (11, 12). Each seat is associated with two air-bag units (15, 16, 20, 21), one of which contains an air-bag to be deployed so as to occupy a space on the inboard side of the seat, and the other of which contains an air-bag to be deployed so as to occupy a space on the outboard side of the seat. There is a sensor and control arrangement (23) to sense impact and to determine which side of the vehicle has been impacted. The sensor and control arrangement (23) generates actuation signals capable of actuating the air-bag unit (15) associated with the first seat (11) closest to the point of impact I, and the air-bag unit (21) of the second seat (12) closest to the point of impact I.Type: GrantFiled: April 15, 2004Date of Patent: May 18, 2010Assignee: Autoliv Development ABInventors: Ola Bostrom, Yngve Haland
