Description

Pressure reduction device for vehicle safety belt

The present invention relates to a device for reducing the feeling of pressure in a seat belt for a vehicle, and in particular, by providing a means for releasing a seat belt that is temporarily locked at the same time as a vehicle crash, a seat belt for a vehicle that can relieve some of the pressure applied to the chest part. It relates to a feeling of pressure reducing device.

In general, a vehicle safety belt is a kind of protective equipment that restrains a driver's body from jumping forward in a vehicle crash or sudden braking.

Such a seat belt is locked by a predetermined locking means when a momentary tension is applied to hold the body of the driver or the occupant.

1 and 2 show clips to keep the seat belt in an adjusted state.

The clip is made of a paper-making tool 110 and a fastener 120, which is inserted back and forth on the belt 100, and a locking lever 130 mounted on the fastener 120 to substantially press and fix the belt 100. Consists of adjusting the length of the belt and then pressing the locking lever 130, the adjusted length of the belt can be fixed.

The clip is to be fixed in a state that the seat belt is released by a certain length so that the tightening force of the belt is not applied when worn, thereby reducing the feeling of pressure on the chest portion of the belt worn for a long time.

If the belt is normally worn in this way, the pressure applied to the chest can be removed using the clip as described above. However, if the belt is locked momentarily during a vehicle crash or sudden braking, the pressure applied to the chest. Since no other means have been suggested to date, and the belt locking action is directly related to safety, a method such as loosening the belt locking degree is not desirable to reduce the pressure on the chest. will be.

Therefore, the present invention has been devised in view of such a point, and is provided with a means for elastically changing the length in the buckle of the seat belt so that the seat belt which is temporarily locked at the same time as the vehicle collision can be released slightly, The purpose of the present invention is to provide a pressure reducing device for a vehicle seat belt that can significantly reduce the pressure applied to the chest within a range that does not affect.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention has a plurality of engaging grooves (10) arranged at regular intervals along the longitudinal direction on both side walls of the inside, the rear end of the case 11 of the upper and lower assembly type of which a certain length is extended to fasten the bolt And, by using a long rod-shaped rear end side by side inserted into the inside of the case 11, the rear end of the buckle 13 is attached to the rear wall surface of the case 11 using the connection band 12 and the A buckle stopper 15 which is engaged with the rear end of the buckle 13 and which can be caught by the locking groove 10 on the inner side wall of the case 11 by using the locking pins 14 of both sides that are elastically flown. In the case 11, the two springs 16 are installed between the front surface of the buckle stopper 15 and the front wall of the case 11 and elastically support the entire buckle 13 and the buckle stopper 15. It is characterized by consisting of.

This will be described in more detail as follows.

3 and 4 are perspective views showing the device for reducing the feeling of pressure of the seat belt according to the present invention.

The pressure reducing device of the present invention is composed of a case 11 of a rectangular box shape having a predetermined space, a buckle 13 assembled in the case 11, a buckle stopper 15, and a spring 16. .

The case 11 has a combination of up and down, and is fastened and fixed on the bottom panel using a portion extending from the rear end.

Inside the case 11, a plurality of locking grooves 10 are formed on both sidewalls at regular intervals along the longitudinal direction, and the locking grooves 10 have locking pins having the buckle stopper 15. 14) can be caught.

The front portion of the buckle 13 has a conventional structure to fasten the tongue, the rear portion is extended in the form of a long rod is inserted side by side inside the case 11 by the connecting strip 12 by the case ( 11) is fixed to the back wall.

At this time, the connection band 12 is made of a plastic material, and the belt including the buckle and the tongue is pulled with a predetermined force so that they can be broken at the same time.

The buckle stopper 15 is integrally coupled to the structure fitted to the rear end of the buckle 13, each of the body is formed with a pin groove 18, the pin groove 18 is engaged with the pin spring 17 The pin 14 can be inserted into the installation.

The locking pin 14 installed as described above is receivable / drawable while receiving the elastic support of the pin spring 17.

The spring 16 is installed inside the case 11 and serves to elastically support the buckle stopper 15 and the entire buckle 13.

That is, when the buckle stopper 15 and the entire buckle 13 are pulled out of the case 11 at the same time as the connection band 12 is broken, the buckle stopper 15 is supported by supporting it while exerting a predetermined elasticity. By preventing the sudden withdrawal of the buckle 13 and) it is possible to effectively reduce the desired pressure feeling in the present invention.

Therefore, looking at the effect of the pressure reducing device of the present invention configured as described above are as follows.

3 shows a state in which the seat belt is normally worn, and in this case, the buckle 13 is not moved by the connecting belt 12 and the spring 16.

4 shows the state in which the pressure reducing device of the present invention is operated.

When the belt is fitted to the body and the tongue 140 is fastened to the buckle 13 while the body is pulled forward by the impact during a collision or sudden braking, the seat belt is momentarily locked, and the belt is applied to the belt at this time. The buckle stopper 15 and the buckle 13 are pulled out of the case 11 while overcoming the force of the spring 16 while the connecting band 12 is broken by the losing tension, so that the belt is pulled out as above. Is a little loose.

As a result of the locking of the belt, a feeling of pressure is applied to the chest and at the same time as the buckle stopper 15 and the buckle 13 are drawn out to some extent, the belt is slightly loosened, so that the feeling of pressure on the chest can be considerably reduced. do.

At this time, the spring 16 in the case 11 prevents the rapid withdrawal of the buckle stopper 15 and the buckle 13, so that the locking effect of the belt can be maintained, and the locking pin in the buckle stopper 15 14 is caught again by the locking groove 10 at a predetermined position when the withdrawal progress is completed, thereby preventing the re-receiving by the reaction force of the spring 16 while maintaining the withdrawn state.

As described above, the present invention provides an apparatus for reducing the feeling of pressure that can loosen the belt slightly when locking the belt, thereby reducing the pressure on the chest.
