Abstract: An airbag device (1100) includes: an inflator (1110); a first panel (1130) that has a first fixing portion (1132) and a second fixing portion (1133) that are different parts from an edge portion (1131) and that face each other; a second panel (1140) that makes up a sack-like airbag along with the first panel (1130); and a regulating member (1150) provided within the airbag. The length from the first fixing portion (1132) to the second fixing portion (1133) of the first panel (1130) is longer than a length from a first part (1151) to a second part (1152) of the regulating member (1150). The airbag has a main bag (1121) and a sub-inflating portion (1122), and when inflated and deployed, gas from the inflator (1110) in introduced to the main bag (1121), the first panel (1130) faces a passenger, and the sub-inflating portion (1122) catches the passenger.

Abstract: A side airbag device capable of restricting an occupant from moving to the inner side in the vehicle width direction while restraining the head of the occupant is inflatable and deployable in a space beside an occupant seated in a vehicle seat. The side airbag device includes an inflator configured to generate a gas and a bag-shaped airbag inflatable and deployable in response to the gas upon activation of the inflator to protect a lateral portion of the occupant. The airbag includes a torso protection portion, and a head protection portion configured to be provided above the torso protection portion and inflatable and deployable between an upper portion of a shoulder of the occupant and a lateral portion of a head of the occupant. The head protection portion is bendable at an acute angle relative to the torso protection portion in an inflated and deployed state of the airbag.

Abstract: A side airbag device includes an inflator and an airbag. The airbag includes a deployable bag and a separator that separates the bag into a first chamber and a second chamber. The first chamber includes a support inflation portion and a protection inflation portion. The support inflation portion is deployable in such a shape that it gradually broadens from its lower end portion toward its upper end portion along a seat-side portion. The protection inflation portion is deployable at one end side of the support inflation portion. The inflator is disposed to supply a gas into the support inflation portion. The separator includes at least one gas distribution hole in a portion thereof that separates the support inflation portion of the first chamber and the second chamber from each other.

Abstract: A side airbag device (1) protects the passenger (90) in the lateral space (92). The airbag (10) has an attaching portion (11) attached to a side section (85) of a seat (80), and is folded so as to be able to deploy from the side section (85) toward the lateral space (92). The inflator (2) generates gas and thereby deploys the airbag (10) to a leading end portion (12) in the deployment direction (F). The airbag (10) has a bellows-like folded section in which a part (30) between the leading end portion (12) and the attaching portion (11) is folded in a bellows-like shape. The bellows-like folded section is disposed in front of the attaching portion (11) in the deployment direction (F), and is folded double toward the back of the deployment direction (F) so that a portion (32) close to the attaching portion (11) is positioned therein.

Abstract: A chamber required to be inflated and deployed at an early stage in an airbag is inflated and deployed in advance so as to protect an occupant at an early stage. An airbag device (1A) is provided with an airbag (10A) which protects an occupant (90) in a vehicle by inflation and deployment by gas, and an inflator (3) which supplies the gas to the airbag (10A). The airbag (10A) has a first chamber (20), a gas distribution port (14) provided in the first chamber (20), and a second chamber (30). The first chamber (20) stores an inflator (3) and is inflated by the gas supplied from the inflator (3). The second chamber (30) surrounds a part of the first chamber (20) including the distribution port (14) and is inflated by the gas supplied from the distribution port (14).

Abstract: An inflator that supplies gas in the event of a vehicle emergency and a curtain airbag that is inflated and deployed by gas introduction from the inflator are included. The curtain airbag includes an airbag body obtained by sewing a pair of base cloths together. The airbag body has, in the portion in which the gas is introduced from the inflator, a sewn part obtained by sewing a pair of edges of the base cloths. The airbag body further includes a protective cloth sewn to each of the pair of edges along the sewn part such that the sewn part is covered from the inside of the airbag body.

Abstract: Gas supplied from gas discharge ports is guided without providing a metal guide tube on the inflator of an airbag device, and the airbag is protected from the gas. An inner tube (50) is connected to a gas inlet (13) formed in an airbag (10), and an inflator (40) around which a fabric member (60) is wound is inserted into and attached to a gas passage (54) formed in the inner tube (50). The fabric member (60) is wound around the inflator (40) several times into a tubular shape such that it covers a plurality of gas discharge ports (42) provided in the inflator (40) and such that one end thereof opens to the inside of the airbag (10), and the fabric member (60) is inserted into the inner tube (50). When the inflator (40) is activated, gas from the gas discharge ports (42) is guided to the inside of the inner tube (50) by the fabric member (60) and is guided and supplied to air chambers (31) and (32) through the gas passage (54), thereby inflating and deploying the airbag (10).
