Patent number: 10207611Abstract: A method for targeted influencing of the deformation behavior of a wall-like structure, in particular a rear wall structure of a vehicle seat, which structure is heated in at least one region at least section by section by means of a laser light source. According to the invention at least one region which influences a strength and/or a tension of the wall-like structure is selectively chosen and is lasered for increasing the strength of the wall-like structure and/or for reducing tensions within the wall-like structure. The wall-like structure is characterized in that in a selectively chosen region the structure has at least one laser-welded seam which is generated by a laser light source of a laser device, increases the strength of the wall-like structure and/or reduces tensions in the wall-like structure.Type: GrantFiled: December 30, 2015Date of Patent: February 19, 2019Assignee: SITECH SITZTECHNIK GMBHInventors: Dawid Rutkowski, Robert Sulowski

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
