摘要： PROBLEM TO BE SOLVED: To increase an adjustment allowance of the internal pressure difference between the upper chamber and the lower chamber when an airbag is inflated. SOLUTION: A side airbag device is equipped with an airbag 20 and a tether 27. The device restricts inflation thickness in the vehicle width direction of the airbag 20 by winding up the tether 27 to the vehicle width direction when the airbag is inflated, while bending the tether 27 upward when the airbag is not inflated, and the device partitions the internal space of the airbag 20 into a lower chamber 33 and the upper chamber 34 of the upper side thereof while restricting the inflation thickness of the airbag in the vehicle width direction. A connection part 37 for connecting in such a state that a cloth part on the vehicle inner side and a cloth part 22 of the airbag 20 are close to each other is provided in the vicinity of the tether 27 in a state bent upward when the airbag 20 is not inflated.

摘要： PROBLEM TO BE SOLVED: To provide an air bag capable of maintaining, by a simple wrapping operation, a state of folding of an air bag body over an approximately entire length of the air bag body, and preventing development/expansion of the air bag from being stagnated at vehicular collision. SOLUTION: The air bag 10 comprises the air bag body 11, and breakable wrapping materials 25, 26 for preventing breaking of a folded state. After the air bag body 11 is folded to be an approximately bar-like shape, the wrapping materials 25, 26 constituted of lengthy materials having flexibility are wrapped around an outer periphery over the approximately entire length of the air bag body 11 so as to be along an axial direction X of the air bag body 11 and so as to obliquely intersect the axial direction X. The wrapping materials 25, 26 are wrapped around the air bag body 11 so that at least one of the winding start portion and winding end portion thereof does not touch a folded portion of the air bag body 11.

摘要： The head-protecting airbag according to the present invention is formed by hollow-weaving method, and includes a gas admissive portion inflatable with inflation gas to separate its vehicle's inner wall and vehicle's outer wall, and a non-admissive portion admitting no inflation gas. The non-admissive portion includes mounting portions arranged in the upper edge of the airbag, and a marginal portion located around the gas admissive portion. The non-admissive portion partially has a two-ply structure where the hollow-woven cloth material separates into vehicle's inner cloth part and outer cloth part from the marginal portion having a one-ply structure. At least one of the mounting portions is formed by folding back a region of the two-ply cloth part to have a four-ply structure. The head-protecting airbag of the present invention remains stably attached to the vehicle body without breakage of the mounting portions even when a strong tension force rapidly and directly acts on mounting-hole peripheries of the mounting portions upon airbag deployment.

摘要： PROBLEM TO BE SOLVED: To provide a head protective airbag which is capable of easily checking the arrangement position and the folding width of bellows folds or twist prevention when the folding is completed, and easily mounted on a vehicle in an adequate posture. SOLUTION: The head protective airbag 19 comprises a mounting part 40 for mounting on the vehicle body side, and a gas flow-in part 21 to enable inflation gas to flow into a space between both wall parts on the in-cabin side and the outer side of the vehicle so as to cover a window. The gas flow-in part 21 is folded so as to arrange a bellows folding part 55 as an upstream side part of the inflation gas, and arrange a folding lump part 56 to be extruded below the bellows folding part 55 when unfolding the bellows folding. Marks 45/46 for checking folds are arranged and marks 48/49/50/5 for checking the twist prevention are arranged at the position of a first fold D1 and a second fold D2 at adequate positions of the bellows folding in the gas flow-in part 21.

摘要： PROBLEM TO BE SOLVED: To provide a side airbag device capable of deploying an airbag in a satisfactory manner. SOLUTION: This side airbag device 14 is provided with the airbag 41 stored in a section sandwiched in between a body 15 of a vehicle 10 and a rear seat 11 and an outer cover 20 formed into such a shape that covers an inner side of a vehicle interior in the section and attached to expose its one face into the vehicle interior. When a shock exceeding the predetermined extent is applied to the body 15, a thin-walled part 24 of the outer cover 20 is broken by the pressure acting by inflation of the airbag 41 in accordance with it, and an opening part is formed in the outer cover 20 to inflate the airbag 41 from the opening part into the vehicle interior. The whole end part on a rear seat 11 side in a section corresponding to the opening part of the outer cover 20 is constituted by an end part of the outer cover 20. COPYRIGHT: (C)2009,JPO&INPIT
