Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steering wheel for a vehicle such as an automobile or a motorcycle.

2. Description of the Related Art Conventional Structures and Problems Generally, in automobiles and motorcycles, electric heaters (2) are incorporated into the handlebars (1) as shown in FIG. 1 in order to make driving in winter more convenient. Figure 2 shows the electric heater (2), (3) in the figure is the lead wire, (4) is a waterproof switch with thermostat, (5)
is the connection terminal.

By the way, the electric heater (2) is attached to a linen cloth (as shown in Figure 3).
6) and cotton cloth (7), and an asbestos-coated electric resistance wire (8) is wired inside the base sheet, which is attached to the handle (1), and a soft resin waterproofing wire is placed on top of it. The coating (9) is applied, and in actual use, the mechanical strength (
(Tension, twist, compression, etc.) is not considered, and the asbestos-coated electrical resistance wire (8) is likely to move or break. In addition, there were other problems such as the asbestos-coated electrical resistance wire (8) felt in the hand, making it difficult to operate, and heat escaping into the handle, making it impossible to warm up quickly.

Furthermore, there is a processing method for the heating element unit as shown in Figs. It is heated and melted.

This is fundamentally different from the purpose of the present invention, and the resin sheet (2a) and the fabric (c) have a drawback that is a major hindrance to the ability to rapidly transmit heat from the heating wire (2η).

Purpose of the Invention The present invention takes into account the above-mentioned conventional problems, and improves the mechanical strength and thermal conductivity of an electric heating wire and a heating unit having this electric heating wire, and also improves the uniform heating of the surface, thereby making it more comfortable. The object of the present invention is to obtain a steering wheel for a vehicle that allows easy steering operation.

Structure of the Invention The present invention provides a vehicle handle in which an electrothermal heating unit is provided on the outer periphery of the handle, in which the handle body is constructed by providing a heat insulating member on the outer periphery of the core body through a synthetic resin member, and A sheet-shaped heat generating unit and an outer skin are stacked on top of each other in order, and the heat generating unit is sequentially laminated with a fiber layer, a heat-melting resin layer, a heating element, and a metal layer from the handle body toward the outer skin and fixed in sequence. It is characterized by
Since a resin coating member is provided on the inner surface of the metal layer to fix the heating wire, and the heating element is constructed by placing resin tubing over the heating wire, the above structure allows stable installation of the heating unit, and The surface is heat-uniformed by the metal layer and heats up quickly, and the heat insulating material prevents heat from escaping to the handle body.

DESCRIPTION OF EMBODIMENTS An embodiment of the vehicle handle of the present invention will be described below in FIGS. 4 to 1.
This will be explained based on Figure 1.

FIG. 4 is a plan view of the handle body, FIG. 5 is a cross-sectional view of the handle body, FIG. 6 is a cross-sectional view of a handle equipped with a heating unit as an embodiment of the vehicle handle of the present invention, and FIG. 8th developed arrangement diagram of the components of the heat generating unit of one embodiment
The figure is a completed sectional view of the heat generating unit of the present invention, FIG. 9 is a configuration diagram of the heat generating wire used in the heat generating unit, FIG.
Figure 1 shows the wiring diagram of the heating wire.

In Fig. 4, 00) is a steering wheel body of an automobile, and the steering wheel body 00), as shown in Fig. 5, consists of a core body 0υ made of metal, a synthetic resin member 02 molded on its outer periphery, and a synthetic resin member 02 molded on its outer periphery. The heat insulation 44' (composed of 13+. As shown in Fig. 6, a sheet-shaped heat generating unit) I41 is coated on the outer periphery of the handle body a@, and the outer periphery of the heat generating unit 041 is covered with an outer skin θ. It is covered.

As shown in Figures 7 and 8, a sheet-shaped heating unit) I
41 is a metal layer (such as aluminum foil) αe,
The heating element 07) consists of a heat generating body αη fixed to the inner surface of the metal layer QB, and the inner surface of the metal layer ae is coated with a low melting point soft resin material such as polyethylene.
As shown in the figure, an inner outer skin C+++ made of a high melting point resin material such as heat-resistant PVC resin, silicone resin, or fluororesin is provided on the outside of the heating wire (2), and an inner outer skin C++ is provided on the outside thereof.
It has an outer skin 4 made of a soft resin material with a lower melting point, such as polyethylene resin. and heating element aη
The outer shell (2) is heated and welded to the inner surface coated with a metal layer (Ie, a low melting point soft resin material).

In the embodiment, the outer skin structure of the heating element 0η is a double tubing structure, but if heat welding can be performed completely, only the inner outer skin Qυ may be used. Furthermore, if the adhesion between the metal layer ae and the heating element aη is mechanically insufficient, a fibrous layer (cotton cloth,
It is also necessary to reinforce the metal layer H with a 0 mark (noncombustible cloth, etc.). In the embodiment, a low melting point soft resin material (such as polyethylene) Ql is used to thermally fuse the metal layer aO, the heating element Q7), and the fiber layer H.

In addition, the heating unit α is processed so that the surface of the metal layer ae is smoothed and the convex portion of the heating element aη is exposed on the surface facing the fiber layer.

In addition, the handle body Go) is made of a molded synthetic resin member a2 with a thinner wall to make it easier to grip. In addition, in order to withstand twisting force and tensile force when operating the handle, a small amount of adhesive is used between each laminated layer such as the insulation material a■, heat generating unit aa1 outer skin α9, etc. to partially fix it, or even large forces are applied. The receiving part may be reinforced with binding thread, etc., and the binding thread (2) used for the outer skin θω
You may also tighten the whole thing tightly. In addition, foamed resin such as urethane, carbon-containing PVC resin, or other silicone resin is installed between the pitches of the wired heating elements αη, which has good thermal conductivity and is hard enough to prevent the heating elements θ from rising to the surface. It is preferable to prevent the heating element aη from protruding onto the surface of the outer skin θω. Further, the heating element θ may be wired in the circumferential direction of the handle body or in a zigzag pattern along the circumference, as shown in FIGS. 10 and 11.

In the vehicle steering wheel having the above structure, since the heating element αη of the heating unit αa combined with the steering wheel body is in close contact with the inner surface of the metal layer aQ, the surface temperature can be uniformly heated without unevenness. In addition, the heating element 0η and the metal layer OQ
is thermally welded, so it has good heat conduction to the metal layer αe.
Provides rapid heating properties. Furthermore, the heating element (+71 is a metal layer (
Since it is fixed to le and further reinforced with a fiber layer α mallet, the heating element (I?) will not move or break when a force such as twisting or pulling is applied when operating the handle. Sheet-like heating unit with heating element aη)Q
41. Insulation material 0311 outer skin α9 etc. are glued and there is no loosening or sagging, and heat is transferred to the handle body α in countries with no insulation material.
You can prevent it from running away to 0.

As described in detail, the vehicle steering wheel of the present invention has a heat generating unit stably incorporated therein, and the outer skin surface quickly warms up.
The surface temperature is uniform, and there is less heat escaping, making it possible to operate the handle comfortably, which has great practical effects.
