<p>Both ends of a sack-like body (11) are fixed to fixing sections (13) provided in a pillar-like frame in the rearmost section of a vehicle, and the sack-like body (11) is housed along an air bag housing space in a portion of a roof (3). The sack-like body (11) is composed of a fabric-made article which shrinks longitudinally when extended widthwise. At the time of a rear-end collision, an air bag is inflated by gas supplied from an inflator (5), and turns into an inflated body, starting from a housed state in the air bag housing space, in such a way that both ends of the air bag are supported by the fixing sections (13), the inflated shape of said inflated body being restricted by the sack-like body (11). This inflated body constrains the head sections of vehicle cabin occupants who move rearward due to the rear-end collision.</p> |
