Abstract
An air-bag (1) having an inflatable region forming two chambers (3,4) divided by a seam (5). The seam extends towards a back part (6) of the air-bag. A gas generator unit (14,15) is located between the end of the seam (5) and the back part (6) of the air-bag. A strap (21) passes through an aperture (8) formed in a terminal part of the seam (5) to draw the terminal part of the seam to the gas generator unit (14,15) thus effectively sealing the two chambers (3,4). The chambers (3,4) may be inflated to different pressures.
