An occupant protection device for a vehicle includes a collision predictor, a main airbag, and a deployment controller. The collision predictor is configured to predict a collision of the vehicle. The main airbag is configured to deploy toward an occupant from a front of the vehicle when a collision of the vehicle is predicted by the collision predictor. The main airbag includes a first deployment part, an arm-push-away deployment part, and a second deployment part. The controller is configured to cause the main airbag to deploy toward the occupant when a collision of the vehicle is predicted by the collision predictor. The controller is configured to, when a collision of the vehicle is predicted by the collision predictor, cause the first deployment part to deploy, subsequently cause the arm-push-away deployment part to deploy to push an arm of the occupant away, and thereafter, cause the second deployment part to deploy.

A vehicle input-operation assistance device includes: a traveling state detection section that detects a traveling state of a vehicle; an operation state detection section that detects an operation state of an operation member gripped by an occupant during operation; a support section that is capable of being stowed in an interior component of the vehicle, and that is capable of projecting from the interior component to a support position where the support section is capable of supporting an elbow of the occupant when the occupant is operating the operation member; and a controller that determines whether or not the elbow of the occupant operating the operation member needs to be supported based on information detected by the traveling state detection section and the operation state detection section and, in cases in which support is determined to be needed, controls the support section to project to the support position.

A vehicle with a vehicle seat arranged in the vehicle interior, which is paired with an occupant protection system, which has at least one crash detection sensor system that detects at least one acceleration value in the event of a crash, which influences the vehicle in the event of a crash so that inertial forces act on the vehicle seat connected to the vehicle and on the occupant sitting on the vehicle seat on the basis of an acceleration value, wherein the acceleration value is used for the crash-adaptive specification, over time, of said displacement travel of the occupant secured with a belt system on the vehicle seat. A total displacement travel of the vehicle seat in the travel direction comprises an additional, exclusively crash-active displacement travel adjoining a displacement travel of the vehicle seat for seat length adjustment in the travel direction.

A vehicle side airbag device including: a side airbag that is accommodated in a folded-up state within a side portion, which is at a vehicle transverse direction outer side at a seatback of a vehicle seat, and, at a time of a side collision, the side airbag inflating and expanding between an upper body of a vehicle occupant and a vehicle side portion, and a vehicle transverse direction inner side surface of the side airbag, which faces the vehicle occupant, sinking in toward a vehicle transverse direction outer side; and a cloth body that is disposed at a vehicle occupant side with respect to the inflated and expanded side airbag, and that spans between front and rear both end portions of the side airbag and is stretched between the front and rear both end portions, a gap being formed between the side airbag and the cloth body.

A vehicle side airbag device including a shoulder protection part and a chest protection part that lifts an occupant's arm in a collision state while protecting the occupant's shoulder. A side airbag (1) is provided at a seat (2) and spread out in a non-inflated state, the contour on the front side in the vehicle body front-back direction has an inflection position C with a curvature change midway between the shoulder protection part X and the chest protection part Y, an upper edge line U upward and a lower edge line L downward from the inflection position. The inflection position is ahead of the shoulder protection part and above a center line F that extends lengthwise of an occupant upper arm A and divides the upper arm into upper and lower portions, and the lower edge line crosses the center line from an upper side to a lower side and positioned under the center line in a lower end position Au of the occupant upper arm.

A seat includes a seatback including a top portion, a seat bottom coupled to the seatback, an airbag, a tether fixed to the seatback below the top portion and attached to the airbag, and an airbag extension. The airbag is inflatable from an undeployed position in the top portion to a deployed position attached to the top portion and extending in front of a front panel of the seatback. The airbag extension is inflatable from the airbag in the deployed position in front of the seat bottom.

An airbag that prevents heavy interference with the head of an occupant during expansion and deployment even when the occupant is not seated in a vehicle seat in a regular position is configured to be positioned to the sides of the center in the left-right direction of a vehicle seat and has a pair of chambers physically coupled by a coupling section that deploy forward of the occupant when expansion and deployment are complete. The pair of chambers are independent during expansion and deployment and expand and deploy frontward from both the left and right sides of the vehicle seat, having side protecting chambers that cover at least the side sections of the occupant. The side protecting chambers are coupled by coupling sections positioned to the sides of the center in the left-right direction of the vehicle seat, and the coupling section is thinner than the side protecting chambers at least during initial expansion and deployment.

A side airbag for protection for vehicle occupants includes an interior wall separating the airbag into upstream and downstream chambers and defining an opening between two chambers adjacent a lower end of the airbag. A flow deflector between the opening and an exterior vent combines with the wall to define a channel therebetween. The channel directs inflation gasses exiting the opening into an upper end of the airbag, after which the gasses must flow around an upper end of the deflector (adjacent an outlet end of the channel) before reaching the exterior vent. The resulting S-shaped flow path serves to maintain the airbag in the inflated state for a longer time and urges an outboard arm of an occupant in a forward an upward direction to reduce the likelihood that that arm may be trapped between the inflating airbag and the occupant's thorax.

A vehicle side airbag device includes a side airbag, an inner tether that extends in the seat forward direction at the seat width direction inner side of the side airbag in the inflated and deployed state and has a distal end portion anchored to the side airbag, and an outer tether that extends outward in the seat width direction from the seat rear side of the side airbag in the inflated and deployed state and has a distal end portion anchored to the side airbag. An upper end portion of the distal end portion of the outer tether is positioned further toward an upper end side of the side airbag than an upper end portion of the distal end portion of the inner tether.

A seat includes a seatback including a top portion, a seat bottom coupled to the seatback, an airbag, a tether fixed to the seatback below the top portion and attached to the airbag, and an airbag extension. The airbag is inflatable from an undeployed position in the top portion to a deployed position attached to the top portion and extending in front of a front panel of the seatback. The airbag extension is inflatable from the airbag in the deployed position in front of the seat bottom.
