摘要： PROBLEM TO BE SOLVED: To quickly complete developing inflation even when a portion difficult to be opened smoothly exists in a door part of an air bag cover. SOLUTION: This air bag 15 is stored in an upper edge side peripheral edge of an opening W in an in-cabin side while covered with the door part 12 of the air bag cover 11 and folded, and is developedly inflated while pushing the door part 12 open to be projected downwards so as to cover the opening W, when gas for inflation flows in. Plural thickness regulating parts 26, 27, 28 for making a thickness of an inflating part 19 uniform by connecting an in-cabin side wall part 19a to an out-cabin side wall part 19b are extended vertically and juxstaposed in a longitudinal direction respectively within an area of the inflating part 19 into which the gas for the inflation for the air bag flows in. The thickness regulating part 28 arranged near a non-smooth development part 12b of the door part is arranged to make its upper end 28a positioned in a lower side compared with an upper end 27a of the adjacent thickness regulating part.

摘要： PROBLEM TO BE SOLVED: To provide an air bag which is easily manufacturable, although having a thin-walled non-inflating part of reduced thickness, and is capable of reducing in manufacturing man-hours and cost. SOLUTION: The air bag 10 is folded and contained in the body side of the peripheral edge of an opening inside a vehicle and is deployed to cover the opening when inflation gas flows into it. The air bag 10 includes an inflating part 14 which is inflated as the inflation gas flows therein so that an interior wall part 15a is separated from an exterior wall part 15b; and the thin-walled non-inflating part 20 thinner than the total thickness of the interior wall part and the exterior wall part and into which the inflation gas is not allowed to flow. The thin-walled non-inflating part 20 is woven with the inflating part 14 into a bag shape and is formed by cutting off a portion 34b of the peripheral wall of the bag shape.

摘要： PROBLEM TO BE SOLVED: To provide an air bag device enabling an air bag to maintain the internal pressure of a fixed value or above for a prescribed time after inflation by suppressing the coated quantity of a coating material. SOLUTION: This air bag is folded and stored in a vehicle to be developed and inflated by the inflow of the inflation gas from an inflator, it is formed by hollow weaving at the average value of 49-50 of warps and wefts per one square inch, and the coating material 25 made of silicone rubber is applied to prevent a gas leakage from meshes. The peak internal pressure of this air bag near the expansion completion is set in response to the coated weight of the coating material to 70 kPa or above at the coated weight in the range of 80-155 g/m2 in the left region including the values on a straight line based on the straight line expressed by equation Y=5X/2-100 (wherein, X in the peak internal pressure (kPa) in an XY coordinate system, and Y is the coated weight (g/m2)).
