A coated base fabric for an airbag has a fabric composed of polyamide fibers provided with a resin coating, wherein the polyamide fibers which compose the base fabric have a total fineness of not less than 100 dtex and not more than 250 dtex and a tenacity of not less than 8.1 cN/dtex and the coated base fabric has a basis weight of not more than 170 g/m.sup.2, packability of the base fabric in accordance with ASTM D6478-02 of not more than 1,400 cm.sup.3, a tear strength in a warp direction and a weft direction of not less than 200 N and an edgecomb resistance in the warp direction and the weft direction of not less than 200 N.

An active bolster for a vehicle is provided, wherein the bolster comprises an expansible hollow interior that is inflatable and is self-supporting in both an inflated and in an uninflated position. The bolster has an inflator module for inflating the expansible hollow interior. The bolster has an inner wall for projecting inwardly into the vehicle and away from the side of the vehicle on inflation of the expansible hollow interior. The bolster may have a relatively non-expansible component located between a first expansible chamber and a second expansible chamber. The bolster may comprise an outer wall having an attachment portion for attaching the outer wall to a portion of the side of the vehicle.

The present invention relates to an inflator mounted on protective equipment, comprising: a main body (100) having a cylindrical structure that is open at the top and bottom thereof, wherein the main body (100) has a key-ball insertion hole (110) and a gas supply hole (120) that are formed on portions of a lateral side thereof, and a bomb (600) for storing compressed air is coupled to the lower side of the main body (100); an eccentric lever (200) that is rotatably coupled to the upper opening of the main body (100) through a rotation shaft (230) and includes a lever (210) that adjusts a downward pressure by rotating an eccentric drum part (220) having the shape of a circular plate; a perforation part (300) that provides a restoring force downward according to the pressure state of the eccentric lever (200) and perforates the bomb (600) to allow the gas in the bomb (600) to be supplied to a user's protective equipment through the gas supply hole (120); and a key-ball (400) that confines the movement of the perforation part (300) while being inserted into the key-ball insertion hole (110) and separates from the key-ball insertion hole (110) according to the state of the outside to operate the perforation part (300).
