The attachment portion includes a protruding portion that protrudes toward the peripheral wall portion side in an end edge farther to a leading end side than a region of penetration of the rivet. The protruding portion is disposed in a position opposing a curved region configuring a boundary region between the peripheral wall portion and the bottom wall portion, and is protruded in such a way as to be oriented farther to a central side of the bottom wall portion than an outer side face of the peripheral wall portion, and an edge on the peripheral wall portion side of a protruding end face is disposed in a state of non-contact with the curved region.

A knee airbag unit (10) of a vehicle occupant restraint system of a motor vehicle is described. The knee airbag unit (10) comprises an airbag module (12), which has a module holder (14), a gas generator (16) and a flexible, non-inherently rigid module housing (18) that at least partially surrounds the gas generator (16) and the airbag in the untriggered state, wherein the gas generator (16), the airbag and the flexible module housing (18) are fastened to the module holder (14). Also provided is a cover (20) forming a module covering and defining an outer side in the installed state of the knee airbag unit (10), which is connected to the airbag module (12). Furthermore, there is an edge-side means (26) securing the cover (20) against lowering, originating from the module holder (14).

A side airbag device with a base member for an inflator to be easily fixed thereto, and a method for manufacturing same is provided. The side airbag device includes: an airbag; an inflator configured to supply the airbag with gas; a base member configured to accommodate the airbag and the inflator, and to be fixed to a vehicle body; an outer covering member configured to cover at least a front side of the base member to form a front-facing interior surface; and a mounting bracket. The mounting bracket includes an inflator fixing portion to which the inflator is fixed and a base member fixing portion which is located in a position different from a position of the inflator fixing portion and fixed to the base member. The base member includes, at a left or right side portion thereof, a bracket fixing portion to which the mounting bracket is fixed.

An inflator bracket includes an elongate body having a first end and a second end. The elongate body defines an aperture proximate to the first end. A hook extends from the first end. An absorption feature has a proximal end coupled to the elongate body proximate to the aperture. The absorption feature defines a curve between the proximal end and a distal end. The distal end is spaced from the elongate body and the aperture.

In an assembly group comprising a cap of a tubular gas generator and a deflector element that deflects gas flowing out of at least one outflow opening of the cap to at least one discharge opening of the deflector element, a deflection surface of the deflector element is arranged radially outwardly of the outflow opening. At least two securing arms of the deflector element extend through the outflow opening and engage behind an edge defining the outflow opening on an inside in a positive connection with the cap. The cap is fixed firmly to an axial end of the tubular gas generator. Subsequently, the deflector element is slid from an outside of the cap with its securing arms through the outflow opening, the securing arms forming a positive connection with the edge of the outflow opening which fixes the deflector element firmly to the cap.

The invention describes an airbag module (10) comprising an airbag (12), an elongate gas generator (14) and a diffusor (16), wherein the gas generator (14) includes an outer housing (18) with outflow openings (20) distributed over the circumference (U) which define an outflow area (22), wherein the outflow area (22) of the gas generator (14) is enclosed by the diffusor (16), wherein the diffusor (16) has a central mount hole (24) into which the outer housing (18) protrudes so that the diffusor (16) circumferentially encloses an axial portion of the outer housing (18) which comprises the outflow area (22), wherein the diffusor (16) includes at least one contact face (26, 26a) and at least two gas guiding surfaces (28a, 28b) on the inner face of the diffusor (16) delimiting the mount hole (24), wherein the contact face (26, 26a) is directly adjacent to the outer housing (18) of the gas generator (14) and the gas guiding surfaces (28a, 28b) are radially spaced apart from the outer housing (18) while forming at least a first collection chamber (30a) and a second collection chamber (30b) into which gas flowing out of the outflow area (22) flows, wherein the first collection chamber (30a) opens into at least one first outlet opening (32a) and the second collection chamber (30b) opens into at least one second outlet opening (32b), wherein the first collection chamber (30a) is separated from the second collection chamber (30b) by the at least one contact face (26) specifically in the form of a separating web (34), wherein the diffusor (16) is completely arranged in an inflatable internal volume of the airbag (12), wherein the airbag (12) comprises at least a first airbag chamber (36a) and a second airbag chamber (36b) which are separated from each other, wherein the gas flowing into the first collection chamber (30a) flows, via the first outlet opening (32a), into the first airbag chamber (36a) of the airbag (12) and the gas flowing into the second collection chamber (30b) flows, via the second outlet opening (32b), into the second airbag chamber (36b) of the airbag (12).

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.
