摘要： PROBLEM TO BE SOLVED: To smoothly deploy a door part by breaking a cover body of an airbag device from a desired position. SOLUTION: A cover body 11 covering a folded airbag is constituted by welding an inner part 22 made of a flexible resin to a lower side of an outer part 21 made of a hard resin. When the airbag is inflated, a tear line 24 forming in the outer part 21 is broken, and a door scheduled part C is deployed to form a projecting port of the airbag. The door scheduled part C and an outline part D are connected to each other by a deformable hinge part provided on the inner part 22. A plurality of deformation line parts 39 are formed in the inner part 22 orthogonal to a center tear line 24a constituting the tear line 24. The inner part 22 is easily deformable by the deformation line parts 39. When deploying the airbag, the tear line 24 is broken from a breakage starting position 27 at a center part of the center tear line 24a to smoothly deploy the door part with good balance.

摘要： An airbag and an airbag device, which are capable of readily improving expansion characteristics of the airbag and reducing manufacturing cost, are provided. An airbag 11 for occupant at passenger's seat includes a first bag 21 and a second bag 22 which is provided inside of the first bag 21. An outside top face portion 36 of the first bag 21 and an inside top face portion 46 of the second bag 22 are brought into a sheet-like intimate contact with each other, and are detachably jointed at the jointing portion 51. The jointing portion 51 is comprised of a breakable seam line 52. Gas is supplied into the second bag 22 to thereby expand the first bag 22, and is supplied into the first bag 21 via a gas distributing portion 48 to thereby expand the first bag 21. In a case where an occupant exists at a predetermined position, the jointing portion 51 breaks away, and the first bag 21 then expands to its maximum. In an OOP state in which the occupant exists in the proximity of the airbag device 1, a head part of the occupant holds the outside top face portion 36 and disallows breakage of the jointing portion 51, so that expansion of the first bag 21 to the occupant side can be restrained and the occupant can be protected with an appropriate force.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of gloss spots while reducing vibration-welding costs, besides preventing an outer door scheduled section (a door section) from causing a peeling phenomenon relative to an inner door reinforcing section (a plate section) upon expansion of an airbag without taking a measure for densifying a weld rib (a weld protrusion). SOLUTION: In this metal arm member, the weld rib 8 formed in a joint surface to the outer door planned section 51b in the inner door reinforcing section 52a, consists of a first weld rib 8a protrudingly formed to be extended in the horizontal direction of an automobile, and a second weld rib 8b protrudingly formed to cross the first weld rib 8a and to spread mutually radially toward a center tear line 51-1a from an edge side in the longitudinal direction of the automobile opposed to the center tear line 51-1a.

摘要： PROBLEM TO BE SOLVED: To solve the problem that when an inner panel is welded onto the rear surface of an undulating outer panel characterized by design, namely, if a welding surface Y which is the rear surface of a separating surface (the surface: X) of the outer panel, and a welding surface Z which is the surface of the inner panel are shaped to greatly offset with respect to a vibration direction, the offset-shaped portions are not subjected to vibration welding by conventional techniques. SOLUTION: In an interior panel for an automobile, on the outer welding surface Y which is the rear surface of the separating surface X of the outer panel 2, and on the inner welding surface Z which is the surface of the inner panel 1 with respect to the vibration direction of the vibration welding, one of the outer welding surface Y of the outer panel 2 and the inner welding surface Z of the inner panel 1 is equipped with a welding rib 3 extending toward the other, and the other is equipped with a welding part of the welding rib 3; and the top part of the welding rib 3 is in the shape of a virtual approximate plane Y' of the outer panel 2, or a virtual approximate plane Z' of the inner panel 1.

摘要： An airbag apparatus comprised of a cover for covering an expanding side of an airbag and forming an opening for the airbag. The cover is comprised of a door portion disposed at the expanding side of the airbag, a surrounding portion surrounding the door portion, a tear portion defining the door portion and tearing due to an expansion force of the airbag, an installation portion protruding from the surrounding portion adjacent to the tear portion toward an opposite side of the expanding side, and a hinge portion connecting the door portion and the surrounding portion located outside of the installation portion.

摘要： PROBLEM TO BE SOLVED: To cover an end portion of an airbag at all times without thickening a case for accommodating the airbag, a retainer for attaching the airbag to the case or the like, and without using expensive highly rigid materials. SOLUTION: An airbag device is structured to include an opening 8a that accommodates a folded airbag 7 in a case 4 having an upper opening and allows the airbag 7 to face to a top opening 4b of the case 4, and fix the airbag 7 by interposing an end portion 7a of the airbag 7 between a retainer 8 provided inside the airbag 7 and a base 4a, so that the airbag 7 is projected to be bulged from the top opening 4b of the case 4 by discharged gas from an inflator 10. A flange 12 extending to project toward the base 4a is formed on the opening 8a of the retainer 8 so as to cover the end portion 7a of the airbag 7 by the flange 12 and the base 4a.

摘要： PROBLEM TO BE SOLVED: To provide a cover of an airbag apparatus capable of demonstrating the stress characteristic according to the position of a hinge part so as to stabilize the development behavior of an airbag while reducing the manufacturing cost. SOLUTION: The cover of the air bag apparatus includes a resin-made outer panel 1, and an inner panel 5 which is arranged on a back side, i.e., on the airbag 8 side of the outer panel 1, and more flexible and deformable than the outer panel 1. The inner panel 5 comprises a fixed portion 5b fixed to a non-expansion part 1b of the outer panel 1, a door reinforcing portion 5c fixed to a door scheduled part 1a, and a hinge portion 5d to integrally connect the fixed portion 5b to the door reinforcing portion 5c across a fracture portion 4. The hinge portion 5d is swollen in the direction separating from the outer panel 1, and gradually thin-walled from the fixed portion 5b side to the door reinforcing portion 5c side.

摘要： PROBLEM TO BE SOLVED: To fracture a fracture scheduled part of a cover body in a desired state when an airbag is inflated and deployed. SOLUTION: The cover body 11 covering the folded airbag is constitutes by vibration-welding an inner part 22 formed of a soft resin to the undersurface of an outer part 21 formed of a hard resin. A tear line 24 is formed in the outer part 21 by injection molding. A projection 48 is formed in the inner part 22 in parallel with a welded rib 44. The projection 48 abuts on a connecting face 29a which is a slope inside a groove 27 of the tear line 24 with the welded rib 44 welded to the outer part 21. When the airbag 6 is inflated, the projection 48 presses the right vicinity of a fracture scheduled line 28 of the tear line 24 to fracture the tear line 24 along the fracture scheduled line 28.

摘要： PROBLEM TO BE SOLVED: To provide an airbag folding method capable of folding an airbag symmetrically and tightly as a whole, and smoothly inflating and deploying the airbag. SOLUTION: The folding method of an airbag 1 comprising an upper face 2, a lower face 3 having a gas introduction opening 4 on a front edge 10 side, right and left side faces 8, and an occupant-opposing face 9 and inflated and deployed in a pyramidal or truncated-pyramidal shape comprises a first step of folding the airbag 1 flat by pulling the right and left side faces 8 in the right-to-left direction to perform the ridge fold, and performing the valley fold of the occupant-opposing face 9 between the upper face 2 and the lower face 3, a second step of folding back the gas introduction opening 4 to the surface on the upper face side, pulling the front edge side 16 of the upper face 2 from the back side of the gas introduction opening 4 and folding it in a bellows shape, and folding the center of the upper face 2 in an isosceles-triangular shape, a third step of folding the airbag 1 in a slender shape, and a fourth step of folding the slender airbag 1 in a bellows shape, and placing it on the back side of the gas introduction opening 4.
