Abstract: A side impact cushion device of a motor vehicle contains at least one impact cushion which can be inflated by a gas generator. The impact cushion in an installation state has an upper portion, a central portion and a lower portion. In this case, the upper portion is arranged substantially horizontally in a deployed state, the central portion is formed in the form of a shell surface of a rotationally symmetrical, developable body, the lower portion can be supported on an upper side of an armrest and a rotational axis of the rotationally symmetrical body is oriented vertically in the deployed state.

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.

Abstract: A vehicle seat part has a cover with a tear seam and an airbag module with an airbag and a force concentrator. The force concentrator partially surrounds the airbag. The concentrator has two end regions connected to the cover adjacent to and on opposing sides of the tear seam. One of the end regions is connected to the cover at a plurality of connecting portions spaced apart from one another.

Abstract: A side airbag system for a vehicle has a primary airbag and a secondary airbag at least partially surrounding the primary airbag. The primary airbag comprises at least one primary vent venting into the secondary airbag and the secondary airbag comprises at least one secondary vent. The primary airbag is inflated by an inflator and the secondary airbag is inflated by gases leaving the primary airbag through the primary vent. The secondary airbag has a panel overlying the primary vent, and inflation of the primary airbag urges the vent and panel in an outboard direction against outboard vehicle structure to restrict flow through the vent. The inflation rates of the primary and secondary airbags are thereby controlled such that the primary airbag protects a vehicle occupant against impacts with a localized load profile and the primary and secondary airbags together protect the occupant against impacts with a distributed load profile.
