Abstract:
1. A safety device for a motor vehicle, comprising: an elastic membrane having a membrane melting point, which partially or completely delimits a hollow space, which is provided for an accident-initiated filling subject to elastically expand the membrane; a gas generator with a filling fluid source communicating with the hollow space; and a carrier that partially delimits the hollow space and defines an outflow opening that communicates the filling fluid from the gas generator to the hollow space, wherein between the filling fluid source and a surface of the membrane facing the hollow space or in the membrane, at least one heat protection means is arranged, which is provided for protecting the membrane from a thermal impact by filling fluid of the filling fluid source, wherein the at least one heat protection means includes a first heat protection means and a second heat protection means, wherein the second heat protection means has a heat protection melting point greater than the membrane melting point and is arranged on a partial region of the surface of the membrane facing the hollow space, wherein the partial region is less than the entire surface of the membrane facing the hollow space, and wherein the first heat protection means is a dimensionally stable plate arranged over the outflow opening on the carrier and oriented to deflect the filling fluid onto the partial region of the surface of the membrane facing the hollow space.
