A side curtain airbag assembly for a motor vehicle

A side curtain airbag assembly for a motor vehicle is disclosed having an elongate airbag 12 with at least one inflatable chamber and also including at least one pair of deployable outwardly extending chambers or tongues 16, 17. The tongues are positioned so as to engage when deployed with an upstanding structural member, such as a "B" post 8; so that the "B" post is sandwiched by the two tongues contacting its front and rear faces (see also figure 7). The tongues act to resist longitudinal movement of the airbag, thereby reducing outward bulging of the airbag if the airbag is subject to an impact force from an interior of the motor vehicle (see figure 4). Each tongue may be supplied with inflation gas via a supply tube 18 having an inlet 18i connected to a lower end of the inflatable chamber. Prior to inflation the supply tubes and tongues may be stowed within the inflatable chamber (figure 5) or external to it (figure 11). A second pair of tongues (26, 27, figure 9) may also be provided near a lower edge of the inflatable chamber.
