The airbag can receive and protect an upper body of the occupant using a rear face side occupant restraining face when inflation is completed. The airbag includes an exhaust port that can discharge an inflating gas and a regulating valve mechanism that restricts a discharge of the inflating gas from the exhaust port. The regulating valve mechanism permits a discharge of the inflating gas from the exhaust port when a protrusion upward of the airbag from the housing portion is restricted, and restricts a discharge of the inflating gas from the exhaust port when a protrusion upward of the airbag from the housing portion is not restricted.

An airbag apparatus is configured to be used for a vehicle seat including an accommodation portion. The airbag apparatus includes an airbag. The airbag is configured such that a portion of the airbag ejected from the accommodation portion to the position beside the headrest is deployed and inflated in a position rearward of the seat back, and is inflated and deployed away from the accommodation portion in the width direction in a position rearward of the headrest, and that another portion of the airbag ejected from the accommodation portion to the position beside the headrest is deployed and inflated in a position forward of the seat back, and is deployed and inflated in a position forward of a head of an occupant seated in the vehicle seat and away from the accommodation portion in the width direction, so as to wrap around the head.

Airbag apparatus

An airbag includes: a bag main body: and regulating units configured to regulate an expansion completed shape of the bag main body. The bag main body has an expansion completed shape as a substantially square cylindrical shape, where a hollow portion which penetrates substantially along a left-right direction is provided and a circumference of the hollow portion is surrounded by an upper expansion portion and a lower expansion portion and a front expansion portion and a rear expansion portion. The regulating units are arranged at a plurality of horizontally symmetrical locations centered on a center of the bag main body on the left-right directional side and each of the regulating units is configured to straddle the hollow portion when viewed from a lateral side in the left-right direction and at least an upper edge side and a lower edge side are connected to the bag main body side.

Front airbag with hollow portion

An occupant protection device includes: an airbag including an upper inflating portion and a lower inflating portion, and a rear inflating portion having a restraint surface that receives the occupant, the airbag being provided with a hollow portion penetrating in a left-right direction in a center; and a protrusion length adjustment unit configured to adjust a protrusion length from an accommodation position to the restraint surface in the airbag. An exhaust port configured to exhaust the inflation gas is disposed on an inner peripheral surface side in the vicinity of an intersection portion between the upper inflation portion and the lower inflation portion of the airbag. When the protrusion length by the protrusion length adjustment unit is adjusted to be long, the upper inflation portion and the lower inflation portion approach each other, so that an edge member approaches the exhaust port, thereby reducing an exhaust amount.

An airbag device includes an actuator of a configuration that causes a string-form coupling member extending from an airbag to be coupled, and controls an inflation aspect of the airbag by causing a state of coupling with the coupling member to be maintained or terminated. The actuator includes a gas generator that can eject a combustion gas and a holder portion that can hold the coupling member. The holder portion includes a holding wall portion, which can hold the wound coupling member on an outer peripheral face side, and a top wall portion that closes a leading end side of the holding wall portion, and a contact region in which the combustion gas can be brought into contact with the coupling member is disposed in a region of the holding wall portion. The actuator causes the coupling member to be severed by causing the combustion gas to come into contact with the coupling member in the contact region, whereby a state of the coupling member being held in the holder portion can be terminated.
