A removable car seat cover for a car seat having an integral side airbag including a side panel having a predetermined pre-weakened failure zone that is pretreated by controlled laser ablation of the side panel. The pre-weakened failure zone is located at or adjacent to an airbag deployment area of a car seat when the car seat cover is installed on the car seat, and is in the form of an elongate strip extending along the side panel. The pre-weakened failure zone has a known bursting strength to thereby facilitate reliable deployment of the side airbag from the car seat as a result of tearing of the pre-weakened zone when the removable car seat cover is installed thereon.

A seat assembly includes a base. The seat assembly includes an air bag supported by the base. The seat assembly includes a cover adjacent the base. The seat assembly includes a first plurality of ribs extending transversely from the cover and toward the base. The seat assembly includes a second plurality of ribs extending transversely from the base and toward the cover.

An apparatus, system, and method for helping to protect occupants of a vehicle seat in the event of a collision. The vehicle seat includes a base with a bottom cushion, a backrest with a back cushion, and a side rest having a side cushion that extends upward from the bottom cushion and forward from the back cushion. The apparatus comprises a deployable restraint stored in a pre-deployment condition in the side rest. The deployable restraint comprising an airbag and an inflator for inflating and deploying the airbag. When inflated to a deployed condition the restrain cushions the occupant against impacts with the side rest.

An airbag device includes an airbag that is supplied with gas during a vehicle collision, and that inflates and deploys from a rear side of a vehicle seat toward a front side via an upper side thereof. In an inflated and deployed state the airbag includes a pair of front-rear chambers extending in a front-rear direction via left and right sides of the head of a passenger, and an airbag body in communication with the pair of front-rear chambers, that is disposed at a front side of the passenger between the pair of front-rear chambers, and that is compression deformed in a state supported by the pair of front-rear chambers during restraint of the passenger. The airbag is configured such that entry of at least the head of the passenger into gaps between the front-rear chambers and the airbag body is suppressed during a latter half of restraining the passenger.

An airbag device including an airbag that inflates and deploys from a seat rear side of a vehicle seat toward a seat front side via a seat upper side. In an inflated and deployed state, the airbag includes a pair of front-rear chambers extending in a front-rear direction via left and right sides of a head of a passenger, an airbag body that is in communication with the pair of front-rear chambers and that is disposed at a seat front side of the passenger between the pair of front-rear chambers, and a pair of rear tethers including one-end portions attached to the airbag body and other-end portions attached to a seatback. At a time of restraint of the passenger, the airbag body is pulled by the rear tethers obliquely rearward and downward such that the front-rear chambers press shoulders of the passenger from a seat upper side.

An airbag device includes an airbag that is supplied with gas generated by an inflator during a vehicle collision and that inflates and deploys from a rear side of a vehicle seat toward a front side via an upper side. In an inflated and deployed state, the airbag includes a pair of front-rear chambers extending in a seat front-rear direction via left and right sides of a head of a passenger, an airbag body that is in communication with the pair of front-rear chambers and that is disposed at a front side of the passenger between the pair of front-rear chambers, and a pair of rear tethers including one-end portions attached to the airbag body and other-end portions attached to a seatback of the vehicle seat. At least a rear tether on a side door side is configured so as to be releasable after a collision of the vehicle.

An airbag device has an airbag. The airbag has a front-rear chamber and an airbag main body. The front-rear chamber has a left and right pair of front-rear extending portions that pass by respective left and right sides of a head of a passenger seated in a vehicle seat and inflate and deploy toward the seat front side, and a connecting portion connecting front end portions of the pair of front-rear extending portions in a seat left-right direction. The airbag main body inflates and deploys toward a side of the passenger at a seat rear side of the connecting portion, later than the front-rear chamber. At a time when the passenger is restrained, the airbag main body is compressed in a seat front-rear direction while stretching the front-rear chamber in the seat front-rear direction.

A side air bag device restraining an occupant at the early stage of the deployment. A seat back has a side support part bulging in a vehicle forward direction at a side part in a vehicle width direction. A seat frame of the seat is provided inside the seat. The side air bag device has an air bag deploying to restrain an occupant and an inflator supplying inflating gas. A side frame part of the seat frame is inside the side support part, and the side air bag device is on an outer side of the side frame. The air bag has a main chamber deploying forward and to an outer side of the side support part and a sub-chamber deploying inside the side support part. The sub-chamber deploys further toward a forward side than a vehicle forward edge of the side frame, at least a front part of the side support part protrudes and deforms toward an occupant side.

A seat includes a seatback having an exterior panel. The seat includes a first member and a second member each being inflatable to an inflated position and defining an inflation chamber, the inflation chambers spaced from each other. The exterior panel extends between and is secured to the first member and the second member external to the inflation chambers in the inflated position.

A vehicular seat capable of reducing a tensile force, which acts on a sewing thread in a webbing sewn part, enables desired expanding operation of a side air bag in the case of emergency. The vehicular seat has an air bag body, provided in the side part of the seat back, which tear-opens the extending part of the trim cover by expansion, to expand from the seat back. A wrap-sewn part, with its terminal end wrap-folded, is provided at an end sewn to the trim cover. The wrap-sewn part has an overlap part where the webbing is overlapped, and a non-overlap part provided at an end of the overlap part in a direction along a sewing line of sewing to the trim cover. The wrap-sewn part is sewn over the overlap and the non-overlap part with respect to the trim cover.
