A center side airbag configured to reduce spacing between an airbag cushion and a passenger in a front passenger seat to safely restrict transverse movement of the passenger in the front passenger seat. The center side airbag includes an airbag cushion configured to be unfolded between a driver seat and a front passenger seat, and a protruding chamber configured to be unfolded by a front passenger seat-side portion of the airbag cushion protruding toward a passenger in the front passenger seat.

An airbag cushion including a cushion rear portion on the inner side of a frame side plate part, a cushion folded portion folded to the outer side of the frame side plate part, and a cushion front portion on the outer side of the frame side plate part. A cover enveloping portion of a cover member has a first end portion engaged with the cushion rear portion and a second end portion that covers a front surface of the cushion folded portion to the cushion front portion and is engaged with a back surface of the cushion folded portion. A cover extension portion connected to the cover enveloping portion by a joint portion and is engaged with the frame side plate part. The cover enveloping portion or the cover extension portion is provided with a weak portion (breakable).

An airbag for a vehicle, such as a side airbag, may be mounted to or proximate to a seat assembly on which a passenger may sit. The side airbag may include a chamber and an inflator configured to cause the chamber to expand toward the passenger to slow an acceleration of the passenger responsive to an imminent impact of the vehicle with another object or surface. Upon deployment of the chamber, the side airbag may cause a portion of the seat assembly (a seat tub, seat pan, and/or cushion coupled thereto) to deform toward the passenger seated thereon while remaining occluded from the passenger by the assembly. In some examples, the chamber may be stored in an unfolded position to allow for a more rapid deployment.

A seat-mounted airbag device includes an inflator, an airbag body, and a guide member. The airbag body includes a front-rear chamber and a tip chamber. The front-rear chamber is deployed forward of a seat through a clearance between a window and a head of an occupant from a side portion of a headrest on a window side by gas ejected from the inflator and disposed between the window and the head of the occupant. The tip chamber is deployed inward in a seat width direction from an end portion of the front-rear chamber on a seat front side and disposed forward of a face of the occupant on the seat front side. The guide member protrudes from the side portion prior to deployment of the airbag body and is interposed between the airbag body and the head of the occupant.

An occupant protection system for protecting a vehicle occupant sitting in a seat includes a seatbelt that includes a lap belt for arresting the pelvis of the occupant, and an airbag disposed in the lap belt. The airbag is coupled to the lap belt in such a manner as to be movable relative to the lap belt in a left and right direction, and includes a main inflatable portion that is deployable in front of upper body of the occupant, and a positioning inflatable portion that protrudes from a lower end region of the main inflatable portion. The positioning inflatable portion includes a contact surface that contacts and is supported by an environmental member which is disposed in a circumference of the lap belt at airbag deployment, whereby helps align a center in the left and right direction of the main inflatable portion generally with that of the upper body.

A side airbag that is to be inflated and deployed to a side of an occupant, includes: a first chamber that is positioned in an upper portion and is to be inflated to a side of a shoulder part of the occupant; and a second chamber that is on a lower side of the first chamber, and a thickness regulating member for reducing an inflation thickness is provided at an upper portion of a front portion of the second chamber.

Disclosed is a seat airbag for a vehicle, the seat airbag including an airbag cushion including lateral cushions configured to be deployed forward from lateral sides of a seatback, and front cushions bent and extending from front ends of the lateral cushions toward a seat center and positioned at a front side of the passenger, and support tethers configured to connect upper portions of the front cushions and an upper portion of the seatback or connect lower portions of the front cushions and a lower portion of the seatback so that the front cushions support a passenger when the passenger is loaded onto the front cushions.

A vehicle includes a floor and a seat supported by the floor. The seat is translatable relative to the floor along a longitudinal axis of the vehicle. An airbag housing is supported by the floor and is disposed alongside the seat. The airbag housing is translatable relative to the floor along the longitudinal axis. An airbag is supported by the airbag housing. The airbag is inflatable to an inflated position that extends from the airbag housing away from the floor.

A side airbag device for restraining an occupant at an early stage by changing a thickness of a chamber includes a cushion formed in a bag shape by combining an outer panel located at an outer side in a vehicle width direction and an inner panel located at an inner side in the vehicle width direction. A baffle spans between the outer panel and the inner panel in an inside of the cushion and partitions the inside of the cushion into a front chamber located at a vehicle front side and a rear chamber located at a vehicle rear side. An inflator is disposed in the rear chamber, and a first tether and a second tether extend from the baffle toward a vehicle rear. The tethers respectively extend from the baffle via both sides of the inflator in the vehicle width direction so as to be connected with a rear end of the cushion.

An inflatable airbag system is disclosed, the inflatable airbag system configured with a securement wrapper and a packaging wrapper, the securement wrapper retaining an inflatable airbag cushion of the inflatable airbag system in a packaging state during assembly of the packaging wrapper to the inflatable airbag system. The securement wrapper prevents or reduces the incidence of excursion of the inflatable airbag cushion from the appropriate packaging state during assembly.
