A side airbag device capable of restricting an occupant from moving to the inner side in the vehicle width direction while restraining the head of the occupant is inflatable and deployable in a space beside an occupant seated in a vehicle seat. The side airbag device includes an inflator configured to generate a gas and a bag-shaped airbag inflatable and deployable in response to the gas upon activation of the inflator to protect a lateral portion of the occupant. The airbag includes a torso protection portion, and a head protection portion configured to be provided above the torso protection portion and inflatable and deployable between an upper portion of a shoulder of the occupant and a lateral portion of a head of the occupant. The head protection portion is bendable at an acute angle relative to the torso protection portion in an inflated and deployed state of the airbag.

A vehicle safety system for helping to protect an occupant of a vehicle seat includes a seatbelt extensible around the occupant to help restrain the occupant in the vehicle seat. The seatbelt includes a lap belt configured to extend across the occupant at the hips. An airbag is secured to the lap belt and configured to inflate and deploy upward from the lap belt to a deployed position in front of the occupant. The system is configured to adjust the deployed position of the airbag in response to the position of the occupant.

A front passenger seat airbag includes an attachment portion provided on a front end side when inflation has been completed, an occupant protection portion provided on a rear end side to protect the occupant when inflation has been completed, and a cavity portion formed at an intermediate portion between the attachment portion and the occupant protection portion in a manner of penetrating the front passenger seat airbag substantially along a left-right direction. A left edge side and/or a right edge side of the occupant protection portion when inflation has been completed is formed with a protruding region protruding rearward and outward with respect to a central region. At least one of upper and lower edges of an occupant side panel is coupled to an end of the peripheral wall panel. An outer peripheral panel portion of the panel portion is a concave portion in a flatly deployed state.

A restraint system for helping to protect an occupant of a vehicle having a roof and a cabin with a seat for the occupant includes an airbag mounted to the vehicle roof. The airbag has a stored condition and is inflatable to a deployed condition having a front-facing occupant receiving portion and an opposite rear-facing portion facing away from the occupant. The airbag has one or more connections with the vehicle roof, with the airbag and the connections being configured such that the roof serves as a reaction surface for supporting the airbag against movement in response to a forward moving occupant impacting the occupant receiving portion. The system is non-reliant on the rear-facing portion of the airbag engaging and using vehicle structure as a reaction surface for supporting the airbag against movement in response to the impacting occupant.

A roof airbag for vehicles is proposed. The roof airbag includes: a main chamber configured to be deployed as gas is introduced therein through a diffuser; and an overlap chamber into which the gas may be introduced and configured to be deployed into a shape that overlaps the main chamber around the diffuser.

A vehicle seat and an airbag system, the seat having a backrest and a squab, extending from the backrest in a longitudinal direction, the backrest extending in height from the squab at a first lower position to a second upper position arranged proximal to shoulders of an occupant in a seated position, the airbag system having an airbag to receive inflating gas from an inflator to inflate the airbag, in which the airbag includes an upper region that extends over a head of the occupant in the seated position and a lower region that extends between a first and second side of the backrest and around a mid-section of the seated occupant, the airbag system having a tether system interconnecting the seat at the second upper position of the backrest and airbag to restrain the lower region of the airbag in the inflated configuration in the longitudinal direction.

A vehicle seat includes a seatback defining an occupant seating area and an airbag mounted to the seatback. The airbag has a top chamber inflatable above the occupant seating area and elongated from the seatback in a seat-forward direction. The airbag has two side chambers inflatable downwardly from the top chamber on opposite sides of the occupant seating area. The top chamber has a plurality of tubular segments each elongated in the seat-forward direction and disposed in a cross-seat direction relative to each other.
