The invention relates to a module () for an occupant-protection device of a motor vehicle. Said module containing a functional element (), which can be activated if the motor vehicle is involved in a collision and which comprises an electrically conductive material and a fixing device () mechanically fixing the functional element () to the bodywork of the motor vehicle. According to the invention, the functional element () is electrically insulated in relation to the bodywork of the motor vehicle. According to the invention, the functional element () is electrically insulated in relation to the bodywork of the motor vehicle. This guarantees that the functional element, which can be activated in a collision, cannot electrically interact with the bodywork of the motor vehicle, is particular in the form of a voltage surge. The invention permits the reliability of a module for an occupant-protection device of a motor vehicle to be increased and prevents potential malfunctions in a simple manner.

Module for an occupant-protection device of a motor vehicle

A vehicle occupant restraint systems including an airbag which has a first airbag chamber and a second airbag chamber or, more generally, a first partial region and a second partial region. The first and the second airbag chambers are connected to each other so that, as a function of the internal pressures present, gas from the first airbag chamber can flow into the second airbag chamber and gas from the second airbag chamber can flow into the first airbag chamber. The second airbag chamber may include an elastic wall, so that, upon a loading of the first airbag chamber, gas flows into the second airbag chamber and, in the process, elastically expands the second airbag chamber.

Vehicle occupant restraint system including an airbag

A restraint device for vehicle occupants, in particular for the lateral restraining of the occupant, comprising an inflatable gas bag (,) and a tensioning device which is connected with the vehicle, engages the gas bag, pulls the gas bag into an intended position on inflation, and holds the gas bag in this position, is characterized in that the tensioning device has at least one inflatable tightening means (,) which shortens in the pulling direction by the inflation and thereby exerts a tensile force on the gas bag.
