Vehicle seats

摘要

An air-bag unit for a vehicle seat including a squab ( 2 ) and a back-rest ( 5 ). The back-rest ( 5 ) includes a frame which is covered with upholstery ( 7 ). An air-bag unit ( 22 ) has an inflatable air-bag ( 28 ) connected to an inflator ( 23 ) to inflate the air-bag 28. The air-bag unit 22 is mounted to the back-rest frame ( 6 ) so as to be located inboard of part of the frame ( 10 ) with the inflator ( 23 ) being located adjacent the rearmost region of the frame ( 6 ) and positioned to direct gas into the air-bag ( 28 ) in a generally forward direction. The arrangement is such that actuation of the air-bag unit ( 22 ) will cause the air-bag ( 28 ) to inflate so that at least part of the air-bag ( 28 ) lies between the frame ( 6 ) and the occupant ( 16 ) of the seat.
