A driver airbagis formed by sewing a front paneland a rear paneltogether. The rear panelhas a horizontal first tuck portion, a second tuck portionextending from a right upper side toward a left lower side, and a third tuck portionextending from a left upper side toward a right lower side. The tuck portionand the tuck portionintersect in an upper part of the rear panel. Since most of the second and third tuck portionsare located in an upper half section of the rear panel, the upper part of the driver airbaghas a larger thickness than that of a lower part when the driver airbagis inflated completely.

Driver airbag and driver airbag device

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.

Airbag and airbag apparatus

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.

Passenger retaining apparatus

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.

Airbag and airbag device

In an airbag, an airbag main body is formed into a bag so as to comprise at least a front panel and a rear panel in an inflated and deployed state, vent holes are formed on the rear panel, vent covers that open and close the vent holes are attached to an outer surface of the rear panel, patch members are attached to the vent covers, and opening degrees of the vent holes are regulated by the vent covers and the patch members inflating in cooperation using a portion of the pressurized gas supplied to the interior of the airbag main body when the airbag main body inflates and deploys.

In an air bag main body which inflates step by step in a first stage and a second stage by bonding its peripheral edge portion and bonding its inner side than the peripheral edge portion, a connecting member bridging between a lid member opening and closing a vent hole and a coupling member can be always set to a tension state by arranging an adjusting portion in the coupling member which defining a maximum facing distance between a front panel and a rear panel in the tension state in each of the first stage and the second stage, and whereby a closed state of the vent hole can be maintained.

Air bag and air bag device

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.

Airbag apparatus

A technology is provided effective for suppressing a load received by an airbag housed in a motor vehicle seat with an airbag module having a construction in which the airbag is developed and expanded from a down side to an upside of a seat cushion against movement of a motor vehicle occupant toward a front side of a motor vehicle, which is in a condition seated in the motor vehicle seat when in occurrence of an accident. In one form, the motor vehicle seat according to the present invention is constructed to house an airbag module in a housing portion provided in a seat pan, and to be provided with an airbag cover that intercepts a housing opening of the housing portion and that covers a housing opening side of the airbag.

Motor vehicle seat, motor vehicle, and airbag module

A technology is provided effective for suppressing a load received by an airbag housed in a motor vehicle seat with an airbag module having a construction in which the airbag is developed and expanded from a down side to an upside of a seat cushion against movement of a motor vehicle occupant toward a front side of a motor vehicle, which is in a condition seated in the motor vehicle seat when in occurrence of an accident. In one form, the motor vehicle seat according to the present invention is constructed to house an airbag module in a housing portion provided in a seat pan, and to be provided with an airbag cover that intercepts a housing opening of the housing portion and that covers a housing opening side of the airbag.
