JPS5934975A - Steering wheel of automobile - Google Patents

Abstract

PURPOSE:To prevent a steering wheel from being cooled, eliminate discomfort due to cooling of hands and secure safety in driving, by providing the steering wheel with a core part, a heating element and a finishing material. CONSTITUTION:A heating element constituted of a positive coefficient thermistor 4' is wound around the core part 2 of a steering wheel, and the periphery of this assembly is covered with a finishing material 3. Accordingly, owing to the resistance-temperature chracteristic of the positive coefficient thermostor, the temperature of the steering wheel can be maintained to substantially constant irresp ectively of the ambient temperature, so that the temperature of the steering wheel is prevented from being excessively raised. Accordingly, a driver can be relieved from trouble for adjusting the temperature of the steering wheel, and since there is no need to provide a controller for a temperature detecting part for maintaining the constant temperature, an excess of space is not required, and the cost is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to heating of automobiles. 1. Structure of conventional examples and problems thereof Conventionally, automobile steering wheels have been made of wood or plastic. For this reason, if the steering wheel is cold in the winter or in a cold region, not only will your hands be very cold and uncomfortable when operating it, but it can also force the driver to drive with one hand, which is extremely dangerous for safety. Become. For this reason, recently, as shown in FIG. 1, the handle 1 has a finishing material 3 on the core 2.
There are some that have a structure wrapped in urethane, but they are still used in cold regions, at night when they are strongly affected by cold radiation, or in open bodies such as convertible cars and forklifts. It was not very effective, and there were problems in terms of eliminating discomfort and ensuring safety.

OBJECTS OF THE INVENTION The present invention solves such conventional problems, and aims to prevent the steering wheel from cooling, eliminate the discomfort caused by cold hands, and ensure safety during driving.

Structure of the Invention In order to achieve this object, the present invention provides a handle with a core, a heating element, and a finishing material.

This configuration allows the handle to generate heat and prevent the handle from cooling down.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIG. Second
In the figure, a band-shaped heating element 4 is wound around the core 2 of the handle, and a finishing material 3 is placed around this.

With the above configuration, the steering wheel itself generates heat and has the effect of preventing cooling, which has the effect of eliminating discomfort caused by cold hands of the driver and ensuring safety by preventing one-handed driving.

Next, another embodiment of the present invention will be described with reference to FIG. The difference in FIG. 3 from the previous embodiment is that a positive temperature coefficient thermistor 4' is used as the heating element. It has the ability to keep the handle temperature almost constant regardless of the temperature, so the handle temperature never gets too hot.
The driver does not have to worry about adjusting the temperature of the steering wheel, and since there is no need for a control device or temperature detection unit to maintain a constant temperature, it does not take up extra space and is also cheaper. effective.

Next, another embodiment of the present invention will be described with reference to FIGS. 5 and 6. The difference in FIG. 6 from the above embodiment is that a nozzle temperature detection part 5 is wound around the core 2 in parallel to the heating element 4, and the heating element 4 is connected to the temperature detection part 5 as shown in FIG. The steering wheel temperature is controlled by a control device 6 connected to the section 6, and with this configuration, the handle temperature can be set freely. This has the effect of maintaining the steering wheel temperature to the driver's preference, improving driver comfort.

Although we have given an example of an automobile steering wheel, this can be widely applied to steering wheels, levers, etc. that need to be operated frequently in low-temperature environments.

Note that the same members are given the same numbers.

Effects of the Invention As described above, the automobile steering wheel of the present invention provides the following effects.

Since the handle is composed of a core, a heating element, and a finishing material, the handle itself generates heat and has the effect of preventing cooling. Therefore, there are effects of eliminating discomfort caused by cold hands of the driver and ensuring safety by preventing one-handed driving.
