A side air bag device is described which is disposed in a space between a vehicle body and a back seat and for which rigidity of attachment to a vehicle body member is improved. The side air bag device provided between a vehicle body and a back seat includes: a base member including a base storage configured to store an air bag and an inflator and a base attachment portion attached to the vehicle body; and a retainer member configured to hold the base storage from a vehicle back side. The retainer member extends from a portion holding the base storage while being bent along the shape of the vehicle body. The retainer member is attached to the vehicle body together with the base attachment portion while being overlapped with the base attachment portion.

The invention relates to a method of folding an airbag (10), especially for a driver airbag module, comprising a front airbag layer (11) which is connected at least in portions to a rear airbag layer (12), the method comprising the following steps of: a) flatly spreading the airbag (10) onto a support surface (15) so that the front airbag layer (11) comes to rest on the rear airbag layer (12), b) folding, especially zigzag folding, at least in portions each of an upper airbag portion (20) and a lower airbag portion (21) in the direction of a transverse axis (Q) of the airbag (10), c) furling each of a left-hand lateral airbag portion (30) and a right-hand lateral airbag portion (31) in the direction of a longitudinal axis (L) of the airbag (10).

The airbag device protects the occupant seated in the vehicle seat disposed in the vehicle. An airbag device includes a first airbag group and a second airbag group that are disposed in the vehicle seat in correspondence with impacts from two different directions and that respectively include a plurality of airbags; a gas generation unit that is disposed in a seat cushion, of the vehicle seat, that supports the buttocks region of the occupant and that generates gas to be supplied to the first airbag group or the second airbag group; and a switching unit that switches the supply of gas to either the first airbag group or the second airbag group.

In one aspect, an apparatus for helping to protect an occupant of a vehicle includes a frontal curtain airbag. The airbag has overlying panels that are interconnected. The airbag is deployable a deployed condition in which the airbag spans across a width of a windshield opening of the vehicle. A restraining panel is separate from and extends widthwise over the panels of the airbag. The restraining panel is connected to the airbag and has a width configured to cause opposing end portions of the deployed airbag to be bent toward one another and into a curved configuration. Pressurization in the deploying airbag tensions the restraining panel widthwise. The tensioned restraining panel maintains the bend in the deploying airbag so that an effective airbag depth is measured between the restraining panel and the airbag.

The disclosure relates to a gas generator—for a vehicle safety system, comprising an ignition unit including a holding element, an igniter and a base. The base is formed by one single plastic injection molding such that the igniter is embedded in the base and the base is injection-molded to the holding element. A membrane which hermetically seals an inner first opening of the holding element is provided.

Proposed is a roof airbag that is disposed at the roof of a vehicle and is deployed into an interior space of the vehicle. A bracket is provided to the roof. An inflator is connected to the bracket and configured to discharge an inflation gas when operated. An airbag cushion is provided to an airbag cover connected to the bracket in a foldable way and deployed into an interior space of the vehicle by the inflation gas supplied by the inflator. A tether is configured such that one end thereof is fixed to the roof side, and the other end of which is connected to the airbag cushion. The tether supports the airbag cushion so that, when the airbag cushion is deployed, the airbag cushion is deployed toward a seat.
