摘要:
The invention relates to a planar heat insulating device, in particular, an item of clothing or a cover for the human body, comprising a shell (2; 12), which is filled with a heat-insulating material (3, 13). The shell (2, 12) has at least one outlet (32) provided, by means of which a reduction of the gas volume in the thermal-insulating device is possible. The insulating power of the thermal-insulating device can thus be varied, in particular reduced, by, for example, a factor of 10, by means of a considerable volume reduction. An item of clothing can thus be produced which may have thermal-insulation properties, optimised to suit the wearers activities with differing levels of physical exertion.

The invention relates to an air mattress comprised of at least one air chamber made of strips of an air-tight, water vapor permeable or water vapor impermeable material that are welded or glued together. The air chamber is provided with a closeable valve for letting air in and out, and the air chamber is filled with a down feather material or a synthetic fiber insulation material.
