Combination of an envelope for a laminar structure providing adaptive thermal insulation and a heat protection shield

Combination of at least one envelope for a laminar structure providing adaptive thermal insulation, and a heat protection shield for the envelope, the envelope enclosing at least one cavity having included therein a gas generating agent having an unactivated configuration and an activated configuration,

• the gas generating agent being adapted to change from the unactivated configuration to the activated configuration, such as to increase a gas pressure inside the cavity, in response to an increase in temperature in the cavity,
• the envelope being configured such that a volume of the envelope increases in response to the increase in gas pressure inside the cavity, the heat protection shield being assigned to the at least one envelope such as to cover at least a heat exposed side of the envelope with respect to a source of heat,
• wherein the heat protection shield is bonded to an outer layer of the envelope within a laterally inner bonding portion, such that a lateral end portion of the heat protection shield projects from the outer layer of the envelope, at least in the activated configuration of the gas generating agent, in such a way as to provide for additional thermal protection by an air gap formed in between the lateral end portion of the heat protection shield and the outer layer of the envelope,
• wherein the laterally inner bonding portion has an essentially dot shaped or circular shaped configuration.
