The disclosure relates to a diffusor for a gas generator of an airbag module, comprising a substantially tubular base body with a longitudinal axis, a baffle cap axially connected to the base body at a first end of the diffusor and a connecting device configured at a second end of the diffusor opposite to the first end. At least one outflow opening is formed in an outer wall of the tubular base body such that gas can flow out of an interior of the diffusor substantially in parallel to a longitudinal axis in the direction of the first end and the second end from the diffusor. The baffle cap is free from an outflow opening. The disclosure further relates to a gas generator comprising such a diffusor, as well as an airbag module including such a gas generator. Moreover, a method for manufacturing the diffusor is also proved.

Airbag inflator system including a housing defining a flow passage leading into an interior of an airbag). A gas generator is arranged in connection with the housing. An activation system provides a signal to the gas generator to cause generation of gas. An aspirator is arranged between the reverse flow valve and the outlet end region and includes an inlet portion alongside the reverse flow valve and an aspiration portion partly separated from the inlet portion to define at least one opening in flow communication with the gas generator. The aspirator is preferably configured to generate gas flow in accordance with the Prandtl-Meyer effect.

In an assembly group (12) consisting of a cap (14) of a diffusor of a tubular gas generator (10) and a deflector element (16), the cap (14) comprises an outflow opening for gas generated by the tubular gas generator (10) and the deflector element (16) comprises a discharge portion (34) having at least one discharge opening (42b) through which gas exits the cap (14). The deflector element (16) is inserted into the outflow opening so that the discharge portion (34) protrudes laterally outwardly through the outflow opening, projects there from the cap (14), and an edge portion of the deflector element (16) abuts on an edge of the outflow opening at an inner face of a wall of the cap (14). The discharge portion (34) of the deflector element (16) is pushed from an interior of the cap (14) through the outflow opening until the edge portion abuts on the inner face of the edge of the outflow opening, and subsequently the cap (14) is firmly fixed to the tubular gas generator (10).

Driver-side knee airbags, for vehicles, are described herein. One airbag has at least one cushion pack. Each cushion pack has an airbag cushion to be deployed. The airbag has an inflator. The inflator is outside of and coupled to the cushion pack, and is for inflating the airbag cushion. The cushion pack is dimensioned to be positioned below the steering column of the vehicle. Another airbag has a single cushion pack. The single cushion pack has a single airbag cushion to deploy. An inflator is inside the single airbag cushion. The single cushion pack is dimensioned to mount in a vertical orientation offset to one side of the steering column of the vehicle. In multiple versions of the airbag, an inflator is dimensioned to mount offset to one side of the steering column of the vehicle.

The invention describes an airbag (10), in particular a head side airbag (10) or a head-thorax side airbag, including at least two opposite fabric layers (12, 14) which form at least one inner wall (13) and one outer wall (15) of the airbag (10), wherein the airbag (10) is manufactured in one piece by a multi-layer weaving process in which the fabric layers (12, 14) are interwoven at least in a peripheral region (16), with a gas generator mount (18) for an external gas generator (20) being disposed in either of the two fabric layers (12, 14). The invention further describes an airbag module (8) comprising an airbag (10) according to the invention as well as a method for manufacturing a one-piece-woven airbag (10) and a method for manufacturing an airbag module (8).

An airbag system for a motor vehicle includes an airbag arrangement with at least one airbag and a gas generator for filling the airbag arrangement. A base body includes two end regions, and an ignition element protrudes from the base body between the two end regions. The folded airbag arrangement in a packed state envelops at least one of the end regions in multiple layers on one part of its outer periphery.

An inflatable cushion for a side of a vehicle is provided, the inflatable cushion having a first sheet of material; a second sheet of material, the first sheet of material being secured to the second sheet of material at a seam to define the inflatable cushion; and wherein the seam consists only of: a first plurality of stitches; a peripheral edge portion of the first sheet of material; and a peripheral edge portion of the second sheet of material; and wherein no adhesives or sealants are applied to the first sheet and the second sheet when the seam is formed by applying the first plurality of stitches.
