A vehicle safety arrangement comprising a seat back support (4a) adapted to be attached to the back of a vehicle seat (50) and a side impact protective air bag module comprising an inflator (1) and a folded inflatable air bag (8). The seat back support (4a) is formed with integrally moulded or extruded flanges forming a housing for the inflator (1) and the air bag (8), and with a gas channel (16) linking the inflator (1) with the air bag (8). The arrangement can be placed outside the seat structure and will not conflict with occupant comfort. Furthermore since it is independent of the seat structure it can be manufactured separately. The arrangement also comprises fewer component parts with attendant cost and weight savings and making it easier to manufacture. The seat back support (4a) is a plastic module which can be snapped or bolted onto the back of a front seat (50) and is generally used to prevent injury to rear passengers such as from submarining. The present invention provides a seat back support (4a) integrated air bag (8) arrangement with either a plastics extruded or a plastics moulded housing design and provides a side impact system that is compact in design and lightweight, easy to assemble and inexpensive.
