LAYERED STRUCTURE PROVIDING ADJUSTABLE HEAT INSULATION Russian patent published in 2015 - IPC A41D31/00 

FIELD: textiles, paper.

SUBSTANCE: invention relates to a layered structure (10) providing adjustable heat insulation and comprising a first layer (12), a second layer (14), at least one cavity (16) formed between the first layer (12) and second layer (14), and this cavity (16) is surrounded by the permeable to water vapour and, at least temporarily gastight casing (20) and a gas-forming agent (18) having an inactivated configuration and an activated configuration, and the gas-forming agent (18) is adapted to transition from the unactivated to the activated configuration, for example to increase the gas pressure in the cavity (16) in response to an increase in temperature in the cavity (16). The first layer (12), the second layer (14) and the cavity (16) are arranged so that the distance (d) between the first layer (12) and the second layer (14) increases in response to increase in gas pressure in the cavity (16).

EFFECT: improvement of the structure.
