[en] The present invention relates to a safety device such as an impact or crash cushion, in particular for a motor vehicle, with an elastic membrane 1, which partially or completely delimits a hollow space, which is provided for the accident initiated filling subject to elastic expansion of the membrane, and with a gas generator 4 with a filling fluid source communicating with the hollow space, wherein between the fluid source and a surface of the membrane facing the hollow space and/or in the membrane at least one heat protection means 20, 21 (22, figure 2) is arranged, which is provided for the protection of the membrane from a thermal impact through the fluid. The heat protection means may comprise one or more of a deflection plate 20 over the opening of the gas generator, a metal coating or film 21 applied to the membrane, a gas diffuser (22), and nano-particles embedded in the membrane. The heat protection means may absorb heat and/or sacrificially melt before the membrane.
