Abstract: An air bag device to be installed in a vehicle provided with a front seat and a rear seat disposed away from each other in a front-rear direction of the vehicle, and a reclining mechanism provided in the front seat to allow a seat back to pivot about a reclining pivot axis includes an air bag that deploys from a back surface of the seat back of the front seat toward the rear seat. At least an upper rear portion of the air bag in a deployed state is formed into an arc shape about the reclining pivot axis in a side view of the vehicle.

Abstract: A seatbelt device for a vehicle comprises a belt which restrains an occupant, a retractor which supports the belt so as to wind up one end of the belt, a frictional-force applier which is configured to apply a frictional force to the belt by contacting the belt, and an actuator to actuate the frictional-force applier so as to change the frictional force.

Abstract: A driver airbag 1 is formed by sewing a front panel 2 and a rear panel 3 together. The rear panel 3 has a horizontal first tuck portion 21, a second tuck portion 22 extending from a right upper side toward a left lower side, and a third tuck portion 23 extending from a left upper side toward a right lower side. The tuck portion 22 and the tuck portion 23 intersect in an upper part of the rear panel 3. Since most of the second and third tuck portions 22, 23 are located in an upper half section of the rear panel 3, the upper part of the driver airbag 1 has a larger thickness than that of a lower part when the driver airbag 1 is inflated completely.

Abstract: An airbag includes an airbag body formed by joining front and rear panels, an inlet of pressurized fluid, a vent hole communicating inside and outside of the airbag body, a regulation portion regulating discharge of the pressurized fluid from the vent hole and a coupling portion temporarily joining the front and rear panels. The inlet and the vent hole are formed on the rear panel. The regulation portion includes a connecting member, a vent hole cover and a link member. The connecting member regulates a thickness of the airbag body in the inflated state. The vent hole cover covers the vent hole and has one end portion supported by the rear panel and the other end portion joined to the coupling portion. The link member has one end portion joined to the vent hole cover and the other end portion joined to the connecting member.

Abstract: A passenger retaining apparatus includes a driver seat airbag and a curtain airbag. The curtain airbag includes first and second inflation portions and a recess portion. The first inflation portion is inflated at a passenger side with respect to the inflated driver seat airbag in a vehicle body longitudinal direction. The second inflation portion is inflated at a wind shield side with respect to the inflated driver seat airbag in the vehicle body longitudinal direction. The recess portion is formed between the first and second inflation portions to engage with the inflated driver seat airbag. The driver seat airbag retains a front surface of a head of the passenger and the first inflation portion retains a side surface of the head of the passenger.

Abstract: An airbag comprises an airbag main body formed into a bag by a front panel and a rear panel, a vent hole formed on the rear panel, a vent cover that is attached to an outer surface of the rear panel and opens and closes the vent hole, a tether provided on the vent cover, a vent patch attached to an inner surface of the rear panel, and a tether cover attached to the inner surface of the rear panel, overlapping the vent patch, wherein: the tether is pulled from a slit formed near the vent hole of the rear panel into the interior of the airbag main body and then inserted through an area between the vent patch and the tether cover.

Abstract: An airbag apparatus includes a gas generator that generates gas, and an airbag inflated and deployed by the gas supplied from the gas generator. The airbag restrains an occupant in a first state in which the occupant's chin is positioned on the airbag apparatus or the occupant in a second state in which the occupant's chin is positioned on a steering wheel. The airbag includes one main exhaust port, a vent cover provided to cover the one main exhaust port, and at least one sub exhaust port without a vent cover. The sub exhaust port exhausts the gas without using the main exhaust port in a state in which the vent cover blocks the main exhaust port due to a folded state of the airbag in an initial stage of an inflating and deploying operation performed to restrain the occupant in the first state or in the second state.

Abstract: Provided are an airbag, an airbag device, and a method for sewing a lid member of an airbag that can make it easier to maintain the internal pressure until inflation and deployment of the airbag are completed and to quickly release gas after an occupant contacts the airbag. An airbag includes a vent hole for releasing gas supplied in the airbag, a lid member for making the vent hole openable and closable, and a tether for applying tension to the lid member. A seam formed by sewing the lid member to the airbag is disposed in a sewing region defined by a straight line shape spaced a predetermined distance from the vent hole, and a curved shape (most curved shape) formed by bringing both ends of the straight line shape close to a center line of the vent hole parallel to the straight line shape. The curvature of the seam can be regulated in view of the lap width between the lid member and the outer edge of the vent hole.
