Abstract: A selectively heatable steering wheel has an electrically activated heating element disposed within a hollow interior of the wheel. The heating element includes an electrically conductive resistance wire for generating heat, a metallic foil sheath positioned around the element so as to provide a desired level of insulation, and a protective plastic sheath disposed around the foil sheath which operates as a protective covering for the foil sheath during an insertion of the sheath within the hollow interior of the wheel. The plastic sheath is provided with improved heat conductive properties through the use of radially directed, through-extending metallic wires which are randomly positioned throughout the sheath and which operate to conduct heat directly from a surface of the heating element to an interior wall surface of the steering wheel's hollow interior.

Abstract: A steering wheel cover assembly includes an electric heating element for electrically heating the wheel and hands of the vehicle driver. The assembly includes a pair of structural elements. One of the structural elements is rotatable in association with the steering wheel, and the other structural element is in a fixed position. The two structural elements have electrical contacts which maintain contact during rotation of the steering wheel. The first and second structural elements are formed of at least two members secured together by mechanical fastening means to permit easy assembly and removal of the structural elements. The assembly also includes means for electrically connecting the electrical contacts of the structural element having a fixed position to a power supply means. An electric circuit having, in series, a switch and a thermostat for sensing the temperature of the steering wheel connects the heating element to the contacts of the rotatable structural element.

Abstract: A source of electrical energy travels along with a vehicle the control elements of which are to be warmed so as to prevent or inhibit icing. The electrical energy is transformed to primarily current in a closed conductive loop. Preferably, the current is induced into the loop by a transformer. The loop comprises at least in part joint segments comprising at least portions of the vehicle's brakes and/or control linkages to be warmed. The amount of current is sufficient in relation to the inherent resistivity of the segments to cause the generation of heat within the segments. Preferably the current is an alternating current of a frequency which causes a majority of the current to travel through the segments on, at, or near the skin of the segments in order to cause the generation of heat to be primarily around the skin of the segments.

Abstract: The instant invention relates to a steering wheel with electric heating and to a process for its manufacture. In a first embodiment of the invention a heating conductor made of spring steel (7) is used and is imbedded in an outer zone of the steering wheel sheath with spring force directed outwardly and which is wound so that it provides interconnected, clamp-like open windings (8). This configuration of the spring wire (7) causes it to adhere to the inside of the torus-shaped foaming ring (5) during the foaming process in manufacture, so that it is thereby held in the desired position and need not be slung around the steering wheel core (6) with individual windings. In a further embodiment of the invention the heating conductor is formed so that the sheath consists of foaming material into which the appropriate amount of conductive particles is incorporated.

The heat insulating material is covering the total circumference on the covering portion while a heating member covers only a part of circumferential surface of heat insulating material. And the heat insulating material is made of any one of polymers such as neoprene rubber foam, chloroprene rubber, chloroprene rubber foam, polyethylene foam, polyurethane and polyurethane foam and expanded material of them. The heating member forms a heater made of a heater wire and a pair of sheet members holding the heater wire.

Abstract: An electrically heated handle, particularly for fishing rods, has an elongated thermally conductive shell enclosing an interior chamber in which is located a solid body of a material having high electrical resistance, such as Steatite, defining a heater core having its entire outer surface in heat transfer engagement with the shell. An elongated electric heating coil, e.g., of Nichrome, extends longitudinally through the interior of the heater core and is connected to an external power source through a switch and power supply conductors extending through the rear end portion of the handle. The front end portion of the handle is formed with an elongated socket chamber thermally insulated from the interior chamber and adapted to receive and fit over the butt end of a fishing rod. Once the heater core of the handle is initially heated, the heat is stored for slow dissipation to the handle and hand of the holder, requiring infrequent replenishing of electric current to the electric heating coil.

Abstract: An electrically heated cover for the steering wheel of an automobile, truck, power boat, aircraft, and the like, which is readily snapped onto the outside of the rim of the wheel. The cover includes an annularly extending sleeve parted along a line facing and parallel to the rim of the steering wheel to permit the sleeve to be readily mounted and removed. The sleeve is comprised of inner and outer separated covers joined at both parting edges and contains an array of electric heating elements arranged in parallel and embedded in layer of thermally conductive, electrically insulative material. A layer of thermal insulation is disposed within the covers between the heating elements and inner cover for inhibiting the flow of heat into the steering wheel. Electric power is supplied to the electric heating element through the circuitry to a horn switch on the steering wheel and is controlled by an illuminated switch on a horn cover on the wheel.

Abstract: In a steering wheel mounted heater, there is provided a heat conductive sheet directly in contact with the outer surface of the rim portion. This conductive sheet is then intimately covered first with an electrically insulating sheet and secondly with an electrically heat generating member. This configuration is provided in order to quickly achieve uniform temperature distribution on a given zone of the steering wheel which zone is most likely gripped by the driver during the vehicle driving.
