<p>An airbag (1) is disclosed having a flexible fabric enclosure (5), an elongate vent (17) and a flow control device (10) attached to the flexible fabric enclosure (5) so as to overlie the vent (17). The flow control device (10) has a gas flow directing portion (11) secured around part of its periphery to the airbag (5) and an end flap portion (12) located inside the fabric enclosure (5) prior to deployment of the airbag (1). The gas flow directing portion (11) is inflated when the airbag (1) is deployed so as to draw the end flap portion (12) of the flow control device (10) through the vent (17). The time taken to draw the end flap portion (12) through the vent (17) delays opening of the flow control device (10) and the gas flow directing portion (11) is orientated so as to direct the flow of gas from the vent (17) away from a user (6) of the airbag (1) when the flow control device (10) is open.</p>
