A seat includes a seat bottom and a seatback coupled to the seat bottom. The seatback includes a headrest and a front face facing the seat bottom. The seat includes an airbag inflatable from an undeployed position to a deployed position. The airbag in the undeployed position is supported by the front face above the headrest. The seat includes a tether extending from the seatback to the airbag.

A vehicle occupant protection device includes: an airbag structured as a single bag that is configured to cover a head area of a vehicle occupant, the airbag being stowed at a headrest or seatback of a vehicle seat, the airbag receiving a gas supply and inflating and expanding toward a seat front side, and the airbag including a front inflation portion that is configured to be inflated at the seat front relative to the head area and a left and right pair of side inflation portions that are connected to the front inflation portion and configured to be inflated at seat sides relative to the head area; and an opening portion that is provided at the airbag, is configured to cover the head area from the seat front side or a seat side, and is openable after the inflation and expansion of the airbag.

A vehicle includes a vehicle-seat assembly. The vehicle-seat assembly includes a vehicle seat having a seatback. The vehicle-seat assembly includes a head restraint having a frame supported by the seatback and a sliding member supported by the frame. The vehicle-seat assembly includes a track between the sliding member and the frame. The sliding member is slidable along the track from an undeployed position to a deployed position. The vehicle-seat assembly includes an airbag inflatable from an uninflated position to an inflated position. The airbag has a base fixed to the sliding member in the uninflated position and the inflated position. The base forces the sliding member from the undeployed position to the deployed position as the airbag moves from the uninflated position to the inflated position.

An occupant safety system for a vehicle seat is disclosed. The motor vehicle seat has a seat face, a backrest that is adjacent to the seat face and a headrest that is arranged at an upper side of the backrest. At least one airbag is arranged in the headrest. The at least one airbag is constructed in such a manner that, in an inflated state, the at least one airbag prevents an occupant without any belt system from contacting a vehicle roof by acting on shoulders of an occupant in the seat.

A vehicle occupant protecting device including: an airbag that is accommodated at an upper portion of a vehicle seat, that receives a supply of gas from an inflator and is inflated and expanded toward a seat front side, and that includes a front inflating portion, which is inflated at a seat front side with respect to a head portion of a vehicle occupant, and a pair of left and right lateral inflating portions, which are connected to the front inflating portion and are inflated at sides of the seat with respect to the head portion, the airbag being structured as an integral bag body that covers the head portion; and reinforcing portions that extend in a seat vertical direction at an interior of a seatback, and that connect an upper portion and a lower portion of a seatback frame that structures a frame of the seatback.

An occupant protecting device including: a seat provided in a vehicle, the seat including a seat cushion, a seat back, and a headrest, and the seat being provided with an air bag that inflates and deploys at least to a front and both of left and right sides of a head of a seated occupant; and a control device that in the case of having detected or predicted a collision of the vehicle, causes the air bag to inflate and deploy, and in the case that the seat is facing an opposite side to a collision side when the collision has been detected or predicted, delays a timing of causing the air bag to inflate and deploy more compared to in the case that the seat is facing the collision side.

A vehicle control device that includes: an airbag device including an airbag, the airbag being configured as an integral bag body for surrounding a head of an occupant with a front deployment section including a front inflation section that is inflated and deployed in front of a seat corresponding to the head and at least one of shoulders or a chest of the occupant, and a left and right pair of lateral deployment sections including lateral inflation sections that are connected to the front deployment section and are inflated and deployed at sides of the head of the occupant; and a controller that, after the airbag device has been actuated, executes a drive-to-refuge mode in which driving of a power unit of a vehicle and steering of a steering system are controlled to drive the vehicle to take refuge at a road shoulder.

A vehicle occupant protection device includes: an airbag that is configured to be stowed in a headrest, to receive a gas supply and is formed as a single bag body that, in an inflated and expanded state, includes a front inflation portion configured to be disposed at the front in a seat front-rear direction relative to a head of a vehicle occupant, and a pair of side inflation portions configured to be disposed at both sides in a seat width direction relative to the head of the vehicle occupant; an inflator that is fixed to an upper portion of a seatback frame in an attitude with a long dimension of the inflator in the seat width direction, the upper portion of the seatback frame extending in the seat width direction; and a fluid communication structure that communicates between the inflator and the airbag to allow a flow of gas.

An occupant protection device includes a multidirectional airbag that inflates and deploys from a state housed in a headrest on receipt of supplied gas. The multidirectional airbag is configured as an integral bag body to surround a head of a seated occupant with a front deployment section and a pair of left and right lateral deployment sections. The front deployment section includes a front inflating portion that deploys to a seat forward direction of the head of the seated occupant and of at least one of a shoulder or chest of the seated occupant. Each of the pair of left and right lateral deployment sections includes a lateral inflating portion that is connected to the front deployment section and inflates and deploys alongside the head of the seated occupant.

Airbag assemblies including a housing assembly to be mounted above a vehicle occupant position, an inflator, and an inflatable cushion are provided. The inflatable cushion can include first and second lateral chambers and a frontal chamber disposed between the first and second lateral chambers. Airbag assemblies including a first inflatable cushion that is configured to deploy at a first lateral side and forward of a vehicle occupant position and a second inflatable cushion that is configured to deploy at a second lateral side and forward of the vehicle occupant position are also provided.
