Patent number: 8388057Abstract: An air-conditioned seat includes a seat area and a backrest, the seat area and/or the backrest being cushioned with foam. For climate-control, a ventilator, in particular a radial ventilator, is provided, which is in operative connection with an air distribution device in the foam of the seat area and/or the backrest, the air distribution device including an air distribution structure on the side (e.g., a B side) facing away from the seated person, as well as air-conducting channels toward the side (e.g., an A side) facing the seated person. The ventilator is to be disposed in the foam itself, on the B side. The air is transported to the A side via the air distribution structure in the form of air trenches introduced into the foam on the B side, and via the air-conducting channels.Type: GrantFiled: July 11, 2007Date of Patent: March 5, 2013Assignees: Volkswagen AG, Sitech Sitztechnik GmbHInventors: Tomas Barkow, Heinz Etzmuss, Hans-Georg Kaiser, Bernd Wilhelm, Harald Vogel, Adrian Sievers, Reinhard Mueller

Patent number: 8267343Abstract: The invention relates to a method for controlling a winding machine for winding a continuously fed winding material on bobbin tubes to wound packages. The winding machine comprises two driven spindles. A traversing device holds a traversing guide. The traversing guide is driven for a traversing movement, whereas the traversing device is driven for a changing movement in a changing direction transverse to the traversing movement. A control device controls both the traversing movement and the changing movement. The movement of said traversing device and said traversing guide is controlled for guiding the winding material from a package wound at a first spindle via a fixed transfer device to the second spindle. The winding material is caught by a catching device associated with the second spindle. The winding material is cut by a cutting device wherein the cutting movement is caused by a rotation of the second spindle.Type: GrantFiled: June 2, 2010Date of Patent: September 18, 2012Assignee: Georg Sahm GmbH & Co. KGInventors: Ernst Döring, Helmut Rabe, Bernd Wilhelm, Matthias Hollstein
