Abstract
Abstract The invention relates to an apparatus for heating people, particularly those travelling on motor cycles or in motor vehicles, such as open motor vehicles, or watercraft, tracked vehicles or working vehicles having internal combustion engines, or working on ocean-going ships, floating drilling platforms, etc, in which a hot air producing apparatus supplied with the waste heat of an internal combustion engine comprising a heat exchanger whose casing tube surrounds the exhaust pipe portion of the internal combustion engine and having a cold air inlet and a hot air outlet connection with a meterable cold air supply, is connected by means of a flexible hose connection to the inner area of a double-layer article of clothing, to which is supplied by means of a blower the hot air produced by the heat exchanger and which on the side facing the person wearing the clothing is provided with hot air outlets.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
322 words
A warming garment particularly suitable for use by motorcycle operators including an air carrying system constructed with air outlet openings facing the body of a wearer, and consisting of air impermeable material constructed in two layers consisting of an inner layer and an outer layer, said layers being connected with one another in sections to form air carrying ducts, said air carrying system being connected to a hot air feeding hose, said garment comprising: weld means connecting said two layers together at selected locations thereon to form said air carrying ducts as a continuous duct network having a plurality of air outlet openings, said air outlet openings facing the body and being adjacent in the inner layer; means connecting said hot air feed hose with said duct-network opening into the space between said two layers at one of the outer or inner layer with insulating coatings being provided at the opposite wall surface of the other layer in the area where said hot air feed hose is connected to said one layer at the wall surfaces of the other layer which faces said one layer; said layers being provided in the connection area and in the hot air inlet area of the hot air feed hose with a reinforcing foil; said garment being combined with a hot air producing device which consists of a bent or straight pipe line section with connecting devices at both sides and with a heat exchanger of a casing tube which surrounds said pipe line section, said casing tube being provided at one side with a cold air inlet opening and having at its other end a hot air outlet nozzle into which a cold air suction nozzle provided with a shutoff valve opens, said hot air outlet nozzle being connected to the suction nozzle of a blower whose pressure connection is provided with a control valve and being connected with a flexible hose of said garment.
