A vehicle airbag component

A vehicle airbag component comprises an airbag 48 configured to be deployed from a seatbelt 30 of a vehicle such that, when inflated, the airbag comprises a recessed region 60 configured to receive the head 54 of a vehicle occupant 26 wearing the seatbelt. The recessed portion may be at least partially defined by two elongate portions 62a,b forming a V-shape, Y-shape, U-shape or X-shape, and may act to resist rotation and lateral displacement of the head. The airbag component may comprise a seatbelt engaging portion such as a receptacle for accommodating the airbag prior to inflation. The receptacle may form part of a sleeve which is movable with respect to the seatbelt. The airbag may be inflated in situations such as when the occupant is judged to be too far from a dashboard airbag (figures 4-6), such as when in an autonomous driving position, for the dashboard airbag to be properly effective, with a control system (figures 9, 10) taking into account the occupant's position before deciding whether to deploy the airbag.
