Abstract (en)
[origin: US5746873A] PCT No. PCT/EP94/03451 Sec. 371 Date Nov. 27, 1996 Sec. 102(e) Date Nov. 27, 1996 PCT Filed Oct. 20, 1994 PCT Pub. No. WO95/28112 PCT Pub. Date Oct. 26, 1995The invention relates to a method of producing an air mattress, which comprises a pump part and a part, which is to be pumped up. A propellant is disposed in the pump part and the wall, which separates the pump part from the part, which is to be pumped up, has a one-way valve and a small opening, through which air can flow back from the part, which is to be pumped up, into the pump part. An inlet opening is disposed in the pump part and an outlet opening is disposed in the part, which is to be pumped up. Pursuant to the invention, a metallic tool is used for welding the pump part wall between the upper and lower covering skins of the air mattress. The tool forms one part of a high-frequency welding machine, having two plates, which lie against the outside of the covering skins. The tool is removed before the edge seals of the air mattress are produced. When the pump part is disposed within the air mattress, a dividable tool is used.
