Patent number: 5170036Abstract: The instant invention relates to the arrangement of one or several connection layers for an electric resistance heating system installed on the film-laminated inside of covering fabrics, said heating system being sealingly connected by bonded or glued additional films, which is assigned to the seat and/or backrest surface, in particular the construction of seat and backrest elements of vehicle seats. The tension release is installed at a distance from the plane of the heat conductors for the attachment of the connection cable, whereby the distance between the plane of the heat conductors, namely of the covering film and the tension release is set by a blank of foamed material that is made of a formed material or some other elastic material and installed at a predetermined location.Type: GrantFiled: April 11, 1991Date of Patent: December 8, 1992Assignee: I. G. Bauerhin GmbH elektro-technische FabrikInventors: Dieter Altmann, Eberhard Haupt

Patent number: 4964674Abstract: A heated seat comprises a molded body, a covering fabric and a first foil lining supported by the molded body, a meandering heating wire disposed in a plane adjacent the covering fabric, the heating wire being covered by a second foil. A connecting cable delivers electric current to the heating wire. The heating wire is connected to the connecting cable on a connecting plate which is disposed at a distance from the plane of the heating wire. A structural block made of a pliant material, such as a foam material, is disposed between the plane of the heating wire and the connecting plate. The connecting plate is at an angle to the plane of the heating wire and the structural block is wedge-shaped in cross-section.Type: GrantFiled: March 7, 1989Date of Patent: October 23, 1990Assignee: I.G. Bauerhin GmbHInventors: Dieter Altmann, Eberhard Haupt, Manfred Knuppel

Patent number: 4825048Abstract: A seat heater for integrated assembly into car seats has at least two or several segments and faces, respectively, of any desired shaping. The heater includes several flat, electrically interconnected resilient heating elements (1.1/1.2) either forming a coherent heating face (1) or conforming to the section-wise individual seat configuration, especially the shaping thereof, with the connection between the individual heating elements (1.1/1.2) being respectively established by a low-strength electrical conductor (3) and the electrical conductor (3) being guided in an insulating resilient sheathing (6) of silicone rubber or the like engaging, at both ends, in partial lengths, each of the heating elements (1.1/1.2 et seq).Type: GrantFiled: March 2, 1988Date of Patent: April 25, 1989Assignee: I.G. Bauerhin GmbH elektro-technische FabrikInventors: Horst-Dieter Altmann, Eberhard Haupt

Patent number: 4817271Abstract: A method for manufacturing a flexible heating appliance comprises placing a heating circuit comprising at least one heating wire between two layers of textile material and combining the latter either directly or with the aid of an adhesive layer, by applying heat and pressure. A lower textile layer consisting of one or several sublayers is placed on the rigid surface of a nail-studded template and the heating circuit is then laid on the lower with its wire being guided about the nail ends protruding from that layer. A second, upper textile layer is then placed on top of the lower one and the heating circuit thereon, and the two layers are joined together by means of a superimposed ironing unit comprising a rigid heatable ironing plate and, on the underside of the latter, an elastic, temperature-stable, heat-conductive pressure plate which covers the remaining protruding ends of the nails, with heating of the ironing unit with pressure and thereby thermally combining the two textile layers.Type: GrantFiled: January 21, 1987Date of Patent: April 4, 1989Assignee: I. G. Bauerhin GmbH, electro-technische FabrikInventors: Dieter Altmann, Eberhard Haupt

Patent number: 4697064Abstract: A process and apparatus for electrically heating vehicle seats by using at least one meandering, insulated heat conductor covered on both sides by thermoplastic foil is disclosed. The heat conductor is spread over a bearing thermoplastic foil and covered with an identical foil. A firmly integrated heating element is then formed by applying heat and pressure. The heat conductors are located in meandering channels which are laid out according to a predetermined plan without any bending to the foils. The heating elements manufactured in this manner are combined with the cushion cores of the seat to be heated. In a preferred embodiment, the thermal deformation stability of the heat conductor insulation exceeds that of the foils by approximately 50%.Type: GrantFiled: February 4, 1986Date of Patent: September 29, 1987Assignee: I.G. Bauerhin GmbH Electro-Technische FabrikInventors: Horst-Dieter Altmann, Eberhard Haupt

Patent number: 4695091Abstract: The invention relates to a heating conductor connection between electrically heated seat and backrest surfaces separated by a bracing trough provided in the padding core. Beneath the bracing trough a bracing wire is bonded in the padding core and a connecting seam of the covering materials is located in the bracing trough. A further bracing wire which is disposed in an apron formed by an insert loop is provided, the two bracing wires being connected via clamping clips.The heated separate surfaces are formed by the heating conductor connections crossing through the bracing trough. These connections take up the mechanical stresses by tension, compression and bending without being endangered.According to the present invention, connecting webs (4.0) of copper strip (4.1), are provided between the heated surfaces (2 and 3) and the copper strip (4.1) consists of woven or knitted material. The connecting heating conductor section (4.2) is laid in meander or wave form, bearing on the copper strip (4.1) thus formed.Type: GrantFiled: November 19, 1986Date of Patent: September 22, 1987Assignee: I.G. Bauerhin GmbH Elektro-Technische FabrikInventors: Horst-Dieter Altmann, Eberhard Haupt

Patent number: 3976855Abstract: An electrical heating mat comprises an electrical resistance heating wire arranged in a loop formation with substantially straight leg portions between curved portions. A plurality of spaced apart spacer strips made of thermoplastic material are provided to hold the heating wire its looped formation. Each spacer strip comprises an elongated narrow strip body having a plurality of spaced open-sided were receiving loops having an inner dimension assuring snap-fit reception of the wire therein. One end of each strip body is provided with a snap-in coupling member dimensioned to snap-fit into a wire receiving loop at the end of an adjacent spacer strip to enable a plurality of mats to be interconnected together to form a larger unit. Spacer lands extending generally parallel to the leg portions of the heating wire may connect the spacer strips together.Type: GrantFiled: December 6, 1974Date of Patent: August 24, 1976Assignee: Firma Wilhelm HauptInventors: Horst Dieter Altmann, Eberhard Haupt

Patent number: 3945088Abstract: The present spacer strips are used to form, for example, electrically heated mats, whereby the strips hold the elongated heating elements in a fixed position relative to each other. For this purpose the strips are provided with grooves into which the elements are inserted with a press-fit and preferably with an elastically yielding press-fit. The strips are further provided along the ends with coupling means for connecting several strips in series with each other. The present strips are formed by heating thermoplastic sheet material and stretching the sheet material over a grooving tool plate then the sheet is pressed or sucked into the grooves of the tool plate. After cooling and removal of the grooved sheet, the sheet is cut into strips whereby the cut extends substantially across the grooves.Type: GrantFiled: December 6, 1974Date of Patent: March 23, 1976Assignee: Firma Wilhelm HauptInventors: Dieter Altmann, Eberhard Haupt
