DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting a vehicle collision detecting sensor for detecting a vehicle collision, and more particularly to a sensor mounting for improving detection accuracy and manufacturability while protecting the sensor. About technology.

2. Description of the Related Art In recent years, an airbag for protecting a driver by, for example, inflating a bag housed in a handle portion from a handle portion toward a driver by charging air when a vehicle such as an automobile collides. A system has been proposed. To operate such an airbag system, it is necessary to detect a collision of the vehicle, and the vehicle is provided with a collision detection sensor.

[0003] Such a vehicle collision detection sensor detects the gravitational acceleration in the front-rear direction (front-rear G) and detects a collision. Therefore, a predetermined mounting is required so that the front-rear G can be reliably transmitted to the sensor. It is necessary to have an angle.
When the cab-over type truck is equipped with an airbag system, the mounting angle of the collision detection sensor is affected by the weight of the vehicle (such as the state of the load). Therefore, the collision detection sensor is mounted in a crushable zone that is not affected by this angle. Although it is necessary, such a crushable zone requires the protection of the sensor because the sensor may be destroyed before the collision is detected.

[0004]

The conventional sensor mounting device has a structure corresponding to the above-mentioned requirements. In addition to the mounting bracket for mounting the sensor on the mounting portion, the sensor mounting device is provided for the purpose of protecting the sensor. A cover bracket for covering the sensor in the front direction is separately provided.

Further, since the mounting angle of the sensor is important as described above, the mounting accuracy of the mounting bracket is ensured by a complicated jig or the like.

However, in such a conventional sensor mounting device, since the mounting bracket and the cover bracket that covers the sensor in the front direction of the sensor are separately provided, the mounting device is complicated, and the mounting accuracy of the mounting bracket is high. It also requires complicated jigs and the like to assure, and it is necessary to perform troublesome fixing by welding at a plurality of places, so that the production work may take a long time as a whole.

Similar to the unit 8, the function of transmitting the front and rear G to the sensor 13 is achieved. The sensor mounting angle assuring plate 10 is connected to the rear end of the mounting plate 7, extends in the lateral direction, and is formed to be inclined along the inclined plate 4 of the pedal bracket 3. Is fixed by spot welding.

The protection plate portion 11 is connected to the front end of the mounting plate portion 7 and extends in the horizontal direction, and has a function of protecting the sensor 13 and a harness 14 described later. In addition, the protection plate 11
Is set at a position away from the bracket body 3A of the pedal bracket 3 so that a predetermined space is formed between the two. A space surrounded by the inside of the mounting bracket 6, that is, the mounting plate portion 7, the upper collision gravity acceleration transmission plate portion 8, the lower collision gravity acceleration transmission plate portion 9, the sensor mounting angle guarantee plate portion 10, and the protection plate portion 11.
