A gas bag module has a gas bag whose wall, in a first state of the gas bag, has at least one pleat that is formed in that opposite sections of the wall lie against each other. The gas bag module further has a holder that holds the opposite sections together and affixes the pleat. The holder can be actively released in response to a signal, as a result of which the gas bag reaches a second state in which the pleat is opened.

Gas bag module

A gas bag module () for a vehicle occupant restraint device includes a gas generator () for filling a gas bag (), and a gas conduit device arranged inside the module. The gas conduit device forces a predetermined, uniform flow direction at least on a portion of the gas emerging from the gas generator ().

Gas bag module for a vehicle occupant restraint device

A gas bag module () includes a gas bag (), the gas bag having a front wall () facing an occupant () in an inflated state of said gas bag () and being engaged by a first end () of a destructible retaining element (), the retaining element () at least partially preventing an unhindered motion of the front wall () when the gas bag () is inflated. The gas bag module further includes a gas generator () for filling the gas bag (), the gas generator () having a first discharge section () for a through flow of a first quantity of gas. The gas generator () has a separate, second discharge section (), which can have a second quantity of gas flow through it in a way that is selectively independent of a release of the first quantity of gas or has a time delay with respect to the release of the first quantity of gas, the second quantity of gas being hot gas, which flows to the retaining element () through the second discharge section () so as to cause a destruction of the retaining element ().

A gas bag module includes a gas generator (), a gas bag () in flow connection with the gas generator, and a module covering. The module covering covers the gas bag and has a separate central part () after opening of the module covering. The gas bag module further has a holding device () for the central part. The holding device has guide means () which on inflation of the gas bag () permit a displacement of the central part () and delimit a displacement of the central part ().
