Abstract: 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.

In case of front collision of the vehicle, an inflator is activated to generate gas, and the gas flows through a diffuser into an airbag main body. The diffuser inflates, and the diffuser and the airbag main body thereby start to deploy above the IP.

The diffuser is provided with a depression, and the depression faces the interfering object M.

Abstract: An airbag of a side airbag apparatus includes an upstream inflation portion, which inflates by inflation gas, and deploys frontward at a side of a vehicle seat. An opening is provided at a wall portion of the upstream inflation portion. A pressure regulator valve closes before an occupant is restrained by the upstream inflation portion, thereby restricting the inflation gas in the upstream inflation portion from flowing through the opening. Upon the occupant restraint, the pressure regulator valve cancels the restriction in response to a change in a tensed state of the dividing portion by an external force applied due to the restraint. A tear seam that connects valve body portions of the pressure regulator valve delays the opening time of the pressure regulator valve upon the occupant restraint by the upstream inflation portion relative to the opening time set only by the pressure regulator valve.

Abstract: In a vehicle side airbag device, when a side airbag is inflated and deployed, a tension cloth disposed bridging an upper side bag portion and a lower side bag portion on the vehicle width direction outer side of the side airbag is pulled up and down. The vehicle width direction inflation width of the side airbag is enlarged, so the vehicle width direction shock absorbing stroke can be ensured by the small-capacity side airbag. The tension cloth functions as a reaction force surface that supports the upper side bag portion from the outer side in the vehicle width direction, so even in a vehicle in which the position of a door beltline is low, a shoulder of an occupant can be restrained at an early stage. In a case where the vehicle has rolled over, the tension cloth protects the side airbag from fragments of a door glass.

Abstract: When an inner bag is inflated inside an outer bag, impact on an occupant received by an airbag is reduced. An inner bag (30) is inflated with gas supplied from an inflator (3). A gas exhaust port (31) is formed on the inner bag (30) and allows the gas to flow from the inner bag (30) in an occupant direction (E). An outer bag (20) accommodates the inner bag (30) and is inflated with the gas supplied from the gas exhaust port (31). A restriction member restricts the inflation of a portion of the inner bag (30) to change a direction of which the gas flows out from the gas exhaust port (31) to avoid the occupant direction. The restriction member breaks during the inflation of the outer bag (20) to release the restriction of the inflation of the inner bag (30).
