Abstract: A curtain airbag and a curtain airbag device that reduce the energy transferred to an occupant even though an internal inflation pressure in a curtain airbag body is low are provided. A tie panel 3 is disposed on a curtain airbag body 2 on a side opposite a vehicle interior. An upper portion and a lower portion of the tie panel 3 are connected to the curtain airbag body 2 by sewing. In an area overlapped with the tie panel 3, the panels 5 and 6 of the curtain airbag body 2 are connected to each other by sewing with linearly connected portions 32 to 35, which extend radially in four directions, so as to form four inflation chambers 8 to 11. The curtain airbag body 2 and the tie panel 3 define a space S therebetween when the curtain airbag body 2 is inflated. The space S is in a pyramidal shape in which a portion around an intersection M of the connected portions 32 to 35 protrudes the most.

Abstract: An airbag for storage at an inner side of the backrest in a vehicle width direction includes a lower folded portion made by folding a lower area of the airbag that is to be situated at a lower side of vehicle upon inflation and deployment, an upper folded portion made by folding an upper area of the airbag that is to be situated at an upper side of vehicle upon the inflation and deployment, and a middle folded portion made by folding a middle area of the airbag that is to be situated between the lower area and the upper area upon the inflation and deployment, wherein the middle folded portion is a roll-folded portion such that a face of the airbag facing away from the inner side upon the inflation and deployment faces inward in the roll-folded portion, the roll-folded portion having the upper folded portion wrapped therein.

Abstract: A curtain airbag includes a curtain airbag main body and a tie panel. The tie panel is arranged on an opposite-interior surface of the curtain airbag main body and is connected to the curtain airbag main body at upper and lower portions of the tie panel. The curtain airbag main body includes first and second panels. At an overlapping area of the curtain main body and the tie panel, the first and second panels are coupled with each other by linear coupling portions which are radially extend toward four directions so as to form four inflation portions. A communication portion communicates two of the four inflation portions with each other. When the curtain airbag main body is inflated, a space is formed between the communication portion and the tie panel.

Abstract: The disclosure discloses a curtain airbag comprising a roll body that is constructed by winding an airbag main body toward an upper edge portion side of a vehicle body, and a tether that is integrally embedded in the airbag main body or is attached to the airbag main body, has a base end connected to at least one end of both ends of the airbag main body in a vehicle body front-back direction, and is provided, at a tip end, with a vehicle body attaching portion for attaching to the vehicle body, the roll body having a derived portion that is formed in the at least one end connected to the tether and that derives the airbag main body on the one end side while pulling in the airbag main body on an side opposite to the one end side, in the winding into a roll shape.

Abstract: In one form, a curtain airbag device is provided having a gas introduction portion that is folded so as to be disposed on a side surface of a folded body of a curtain airbag main body on a roof side portion side. When the vehicle is involved in a side collision or an overturn, an inflator discharges a gas, which is supplied to a curtain airbag, thereby causing the curtain airbag to start to be inflated. In this case, the gas from the inflator initially flows into the gas introduction portion so as to inflate the gas introduction portion. Thus, the inflating force of the folded body of the curtain airbag main body and the inflating pressure of the gas introduction portion are superposed each other so as to press a lower edge of a roof side garnish toward the inside of the vehicle cabin.

Abstract: A side airbag device incorporates an airbag which is fixed to and held by a vehicle so as to be folded in roll form, from a front portion to a rear portion of the vehicle, and which is expanded and developed like a curtain parallel with the inner surface of the side wall of the vehicle by a gas of an inflator when a collision is detected. An airbag support belt is attached to a portion, in close proximity to a top edge of the airbag and close to an attachment position of the inflator, of the airbag. The airbag support belt is wound around the circumferential surface of the inflator and a tip locking hole of the airbag support belt is fixed to a locking projection provided on the inflator, whereby the inflator is integrated with a part of the airbag which is folded in roll form.

Abstract: The curtain airbag includes: a curtain bag section configured with cloth panels joined in a bag shape, housed prior to use in a folded state in a vehicle roof side edge section and deploying and inflating downwards when injected with deployment gas; a collision detector for detecting a collision and/or signs of an imminent collision of the vehicle; a gas generator for supplying the deployment gas to the curtain bag section in response to a detection result of the collision detector; and a guide member configured with a cloth panel, rolled up from the bottom of the curtain bag section that has been folded prior to use, via the vehicle width direction inside towards the top of the curtain bag section, the guide member being disposed at a position overlapping with the vehicle front-rear direction position of an interior member provided inside the vehicle compartment.

Abstract: A curtain airbag that can be inflated with gas from an inflator and deployed along a side surface of a vehicle cabin. The curtain airbag includes, in an occupant restraint area corresponding to an occupant's position, a multistage chamber section comprising an upper chamber that is arranged at an upper side; a lower chamber that is arranged below the upper chamber; and a discharge passage that is arranged at a middle portion in a vertical direction between the upper chamber and the lower chamber. The discharge passage communicates with at least one of said upper chamber and said lower chamber to discharge gas from said upper chamber and/or said lower chamber through the discharge passage and is adapted to reduce its cross section when pressed by the occupant's head.

Abstract: A curtain side-airbag device includes an airbag extending from front to rear of a vehicle, a plurality of inflatable support portions provided in the airbag and communicating with each other, and an inflator. The airbag is maintained in a folded state and secured in a vehicle body so that the airbag extends along an upper edge of an inner side surface of a vehicle cabin. The airbag is deployed in a form of a curtain along the inner side surface of the vehicle cabin. The airbag has an upper edge, a non-inflatable peripheral portion surrounding the inflatable support portions, and a strap provided between the upper edge and the non-inflatable peripheral portion of the airbag. The strap regulates a direction of deployment upon inflation of the inflatable support portions.
