The invention relates to an airbag module for a motor vehicle, comprising a gas sack, that can be inflated in order to protect a person by feeding gas into the gas sack, an openable reservoir for storing a coolant, wherein the reservoir comprises a first and a second portion, the second portion connected to the first portion, at least one outflow opening of the reservoir formed in the second portion, through which the coolant, for cooling the gas fed into the gas sack, can leave the reservoir, and a closure element for closing the outflow opening. According to the invention it is provided that the closure element divides the reservoir into the two portions, and that the coolant is arranged in the first portion, wherein the closure element seals the first portion of the reservoir with respect to the second portion of the reservoir. Further, the invention relates to a method for producing an airbag module.

Airbag module for a motor vehicle

An airbag module for a motor vehicle, including an airbag folded to form an airbag package; a component of the airbag module, which via a first component part for inflating the airbag with gas and/or for fastening the airbag to a motor vehicle part cooperates with the airbag; and a protective covering which encloses the airbag in a gastight manner. The protective covering also encloses the first component part and comprises at least one opening, through which a second component part connected to the first component part projects from the space enclosed by the protective covering, the opening of the protective covering being closed in a gastight manner by means of a sealing element.

A module assembly for an airbag device for protecting occupants of motor vehicles includes a carrier for the assembly, an inflatable airbag packet, a flexible protective envelope, and a fixing mechanism. The airbag packet is fixed to the carrier. The airbag packet is accommodated in the flexible protective envelope. The protective enveloped can be closed off in a gastight manner. The fixing mechanism fixes the airbag packet to the carrier. The fixing mechanism includes a holding element. The holding element, which includes a securing mechanism provided on the carrier to fix the airbag packet to the carrier, extends along an edge of the airbag packet. The securing mechanism is formed integrally on the carrier and is resiliently pivotable with respect to a lateral section of the carrier. Alternatively, the securing mechanism is fixed on the carrier as a separate assembly.

Airbag module assembly

A process for producing an airbag packet for an airbag module is provided. The airbag is folded up in a folding apparatus to form an airbag packet. Then, the airbag packet is enclosed in a gastight manner by a flexible envelope, wherein the airbag packet is at least partially enclosed by the envelope while it is still in the folding apparatus.
