Abstract:
1. An insulation structure for an internal insulation of a vehicle, for arrangement in an intermediate space between an internal paneling of the vehicle and an outside skin of the vehicle, the insulation structure comprising: an insulation package arranged in the intermediate space between the internal paneling of the vehicle and the outside skin of the vehicle; an insulation core embedded in the insulation package; and an outer film, comprised of a film envelope and two hose-like end sections formed at opposite ends of the film envelope, each of the two hose-like end sections being outside of the film envelope and on opposite outer edges of the outer film, respectively, and extending beyond an outer periphery of the insulation package, and each of the two hose-like end sections being folded in a Z-shape such that each of the two hose-like end sections form a flat Z-fold attachment section having film fold regions laid one on top of another, and the film fold regions being formed into a compacted end body section by application of pressure and heat, the flat Z-fold attachment sections of each of the two hose-like end sections being at opposite ends of the film envelope, completely enveloping the insulation package within an enclosure formed only by the film envelope and the two flat Z-fold attachment sections, such that the outer film provides an obstruction to fire.
