Description

[Detailed description of the invention] Industrial applications The present invention relates to a steering wheel for a vehicle.

Conventional Structures and Problems There are examples of conventional handlebars used in motorcycles and the like as shown in FIGS. 1 to 3. That is, 1.1' in Figs. 1 to 3 is a small sheet-like electric heating cloth, 2
is an asbestos coated electric resistance wire, 3 is an electric wire cord, 4.4' is an electric wire cord, 5 is a waterproof switch with a thermostat, 6
．． 6' is a terminal, 7.7' is a fastener, a is linen cloth, b is cotton cloth, and C is a soft resin waterproof sheet.

This is a cotton fabric with asbestos-coated electrical resistance wires 2 arranged on it, and has mechanical strength (tensile strength) when operating the handle while holding it in the hand during actual use.

Since there is no consideration given to twisting, compression, etc., for example, when the asbestos-coated electrical resistance wire 2 is used for the handle, it is likely to break due to tension, twisting, etc. In addition, in terms of the feeling of use, the asbestos-coated electric resistance wire 2 feels in the hand and is difficult to operate, and since no insulation material is used, heat escapes to the handle itself, causing problems such as the handle not becoming warm quickly. .

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and aims to improve the mechanical strength of the heating wire of the heating element, improve the mechanical strength and heat conduction characteristics of the heating element fixing part, and further improve the temperature uniformity of the handle surface. The objective is to provide a highly safe vehicle steering wheel that has improved characteristics and allows for more comfortable steering operation.

Structure of the Invention In order to achieve the above object, the present invention forms a heating element by closely contacting a heating element and a reinforcing material on both sides of a heating wire, and also provides this heating element between a heat insulating material and a skin. It is.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 to 8.

Figure 4 shows the appearance of a steering wheel 1 for a general automobile, in which a molded resin 3 is provided on the outside of an iron core 2, and an outer skin 4 is provided.
is covered.

FIG. 6 is an enlarged sectional view showing a handle 1 having a core material 2 and a molded resin 3, and a heat insulating material 5, a heating element A, and an outer skin 4 provided on the outer periphery thereof. The outer skin 4 is fixed by continuously tying both ends of its long sides with a knot 13.

FIG. 7 shows a heating element A, in which one side of a heat equalizing member 7 made of aluminum foil is coated with a low melting point soft resin material (polyethylene, etc.), and when the heating wire 8 is heat-sealed, the side surface of the heating wire 8 is coated. It is coated with a low melting point resin material (polyethylene, etc.), a reinforcing material 6 such as cotton cloth is applied, and heat-sealing processing is performed at the same time. In this case, the heat-sealing process is performed on the surface of the heat equalizing member 7 so that unevenness due to the heating wire 8 does not appear.

FIG. 8 is a configuration diagram of the heating line 8. As shown in FIG. The heating element 8 has a core thread (Kevlar, Tetron resin) 10 wound around a heat-generating wire 9 made from a round wire into a flattened wire in a spiral shape, and its outer sheath is double-walled with resin tubing. The outer sheath 11 is made of a high melting point soft resin material (heat-resistant PVC resin, silicone resin, fluororesin, etc.), and the outer sheath 12 is made of a low melting point soft resin material in order to be thermally fused to the heat equalizing member 7 and the reinforcing material 6. (polyethylene resin) is used.

In the above embodiment, the heating wire 8 is inserted in the circumferential direction of the handle 10, but there is no problem if the heating wire 8 is arranged in a meandering manner as shown in FIG.

Effects of the Invention As is clear from the above explanation, in the present invention, since the heat equalizing member and the outer skin of the heating element are in close contact with each other, the surface temperature can be evenly heated without unevenness. In addition, since the heating wire and the heat equalizing member are in close contact with each other, heat conduction is good and heats up quickly.

Furthermore, the surface of the handle is always gripped with bare hands, and torsional and tensile forces are always applied during operation, but since the heating wire, heat equalizing member, and reinforcing material are in close contact, the heating element does not move. Moreover, it does not make your hands feel uncomfortable.
