Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of troublesome installation of a hands-free microphone for a long time and an increase in the risk of an accident because it is troublesome to attach the hands-free microphone to and detach it from the body every time when getting in or getting out a car so that speaking by a cellular phone is carried out with it held by a hand and the hands-free microphone hooked on an ear allows outdoor sound to be heard only at one ear based on the fact that there are many kinds of hands-free microphones for using the cellular phone during driving but many of them have mechanism allowing concentration to be possibly lost during driving. <P>SOLUTION: The microphone part of the hands-free device is woven into a seat belt which is obligatorily worn during driving. The microphone used in a present cellular phone is extremely small and has a diameter of approximately 6 mm and only a thickness of approximately 1.2 mm. The seat belt has a width of approximately 50 mm and a thickness of approximately 1.3 mm, so that the microphone is sufficiently incorporated into the seat belt. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  Seat belt, ultra-small microphone.

  Seat belt, ultra-small microphone, flexible and durable wiring material.

There are many types of hands-free microphones for using a mobile phone while driving, but it is also true that there are many mechanisms that can detract from the concentration during driving. Each time you get in and out of a car, it's cumbersome to attach or remove the hands-free microphone on your body, and you end up driving dangerously with your mobile phone in hand. Hands-free microphones that can be put on the ear can only hear one of the external sounds, increasing the risk of accidents and making it difficult to wear for a long time.

The microphone part of the hands-free device is woven into the seat belt that must be worn while driving. Microphones used in current mobile phones are also extremely small in size and are only about 6 mm in diameter and about 1.2 mm thick, but seat belts are about 50 mm wide and 1.3 mm thick, It can be built in enough.

If a short-range communication interface such as Bluetooth can be used, it is possible to make a call simply by getting into the car with a mobile phone, and the user can hardly be aware of the use of the hands-free device. Secondarily, according to the present invention, since the user wants to make a call, the wearing rate of the seat belt that does not easily increase is improved, and the number of injured persons due to traffic accidents is reduced.

The mic part of the hands-free device is woven into the seat belt that must be worn while driving. The multi-wiring from the microphone to the vehicle body uses flexible, thin and durable flex-type wiring material, and connects the microphone and other parts via a lock bracket or seat belt attachment. By using multi-wiring, it is possible to take measures against disconnection, to attach a plurality of microphones, and to attach an extension microphone. The structure of the seat belts looks the same at first glance, but in fact it varies depending on the car, so it will be a multi-wiring from the microphone to the car body that matches the individual structure. Whatever the structure, the function as the most important safety device for the seat belt is designed to work. Break prevention reinforcement is implemented between the seat belt, microphone and multi-wiring. One idea is to increase the width of the seat belt, which is currently about 50 mm, to ensure the strength. The microphone should be placed in front of the driver and in front of the shoulder when wearing the seat belt so that it does not get caught during emergency operation. Usually, the seat belt is wound around a pillar (column portion) of the vehicle body, but it is desirable that the microphone be stopped in front of the take-in portion, so that the lower portion of the seat belt is also slightly wound. As shown in FIG. 1, the shape of the triangular seat belt anchor and the intake port of the vehicle body pillar is made to be a shape with little hooking of the microphone. The microphone part itself uses a sound insulation material as well as a cushioning material when the seat belt expands and contracts, and also uses a custom-made material with a small diameter, a flexible material, and a material with shape memory. The microphone is capable of removing the frictional noise between the seat belt and the driver's clothing other than the wearer's voice, with noise canceling software and sound insulation structure. Only the microphone and its multi-wiring are woven into the seat belt, and other parts necessary for the hands-free function are separate parts. I also want high-quality sound using an echo canceller, etc., two-way simultaneous call, automatic incoming call, automatic call termination, and one-touch dialing that keeps my hands off the handle, which are necessary for using a secure mobile phone. Since it is necessary to arrange the vehicle in an appropriate interior space, it is desirable to install the present invention as a manufacturer option. When the extension microphone is attached to the microphone multi-wiring and the distance from the mouth is shortened, the microphone part has a structure and material that does not harm the driver's face. It is assumed that the car has a seat belt support column, but it can be equipped with a hands-free microphone.

"Effect of the embodiment"
You can use the hands-free function just by setting the mobile phone in the holder in the car. If a device mounting method is devised, a clean hands-free call environment can be realized. The microphone in the seat belt is closer to the driver's mouth than most other hands-free microphones, so the sound collection efficiency is high.

"Other embodiments"
The operability can be further enhanced by providing a hands-free microphone operation switch around the driver's abdomen on the multi-wiring that is not wound when the seat belt is retracted. Attach an acoustic vent filter that allows sound to pass through the microphone pinhole without passing water. When the multi-wiring is used as a core material that fits the seat belt in a shape along the rounded human body, the feeling of pressure when the seat belt is worn is somewhat reduced. The principle is the same for multipoint fixed seat belts with four or more points.

A perspective view of the present invention (in the case of a three-point seat belt). FIG. 2 is an enlarged cross-sectional view of the present invention (the actual seat belt thickness is approximately 1.3 mm).

Claims (4)

Seat belt incorporating a hands-free microphone and its multi-wiring. By interweaving a plurality of microphones according to the first aspect, the optimum microphone can be selected and used in accordance with the driving posture of the driver, or the optimum microphone can be selected even if the driver becomes another driver having a different physique. A seat belt that can be used as a spare microphone in the event of a malfunction of the microphone. In the form of claim 1, in order to increase the sound collecting effect, an extension microphone can be attached to the connection terminal of the microphone multi-wiring, and the distance from the driver's mouth is shortened.
