Description

Apparatus loosening pressure of car seat belt

The present invention relates to a vehicle seat belt pressure relief device, and more particularly, to adjust the tightening length by pulling the seat belt once to relieve the seat belt installed in the vehicle from pressing the occupant, and to fix it by pulling it again, but rotate It relates to a vehicle seat belt pressure relief device configured to reduce the possibility of damage and loss due to impact and increase ease of use by integrally molding and manufacturing a connecting means and a guide means through an elastic connecting bar.

When driving a vehicle, it is legally required to wear a seat belt for safety.

However, in general, when the seat belt is pulled and filled in the seat belt buckle before driving, the seat belt is constantly returned to its original position so that the seat belt is in close contact with the body of the occupant due to the pulling force of the spring of a retracter installed in the vehicle. This puts pressure on the occupant's body.

For this reason, there are many cases where the seat belt is not worn due to a feeling of pressure due to excessive tightening when the seat belt is worn.

In order to relieve the pressure caused by the tightening of the seat belt when wearing the seat belt, various types of fixing devices such as seat belt clips are used, but most of these are used to loosen the seat belt before driving so that the seat belt does not tighten, and then the seat belt is not rewound. Since it is a device that is fixed to prevent it from being used, the seat belt must be returned to its original position by releasing the fixing device after use.

Therefore, it is very inconvenient to stretch and fix the seat belt each time, and then release it again to return to the original position. Otherwise, after use, the seat belt is left unattended on the seat, which is unsightly and gets in the way.

In addition, there are some electrical and electronic devices that block and control the rewinding force of the retractor, but these products have complex structures and many problems in terms of production cost and efficiency.

On the other hand, in order to solve this problem, the present applicant (Patent Document 0001) through Korean Patent Publication No. 10-1280565, has proposed a vehicle seat belt pressure relief device capable of adjusting the tightening length.

In addition, each of the parts constituting the vehicle seat belt pressure relief device is a very small part, and the fastening pin 420 could only work in the form of a pin to facilitate fastening.

Therefore, when assembling after injection operation, the operator has to forcefully insert a very small fastening pin 420 to connect the rotation connecting means 400 and the guide means 500, so an excessive assembly time is inevitably required, and the fastening pins ( 420) has a very high risk of loss even during the assembly process as it is a very small part.

On the other hand, the guide means 500 connected to the rotation connection means 400 has a structure in which it cannot but move left and right according to the shape of the cam groove 180 .

The left and right movements of the guide means 500 are made by the fastening pin 420 serving as a hinge shaft, and the fastening pin 420 has no choice but to continue to vibrate according to multiple uses, and as time passes, the fastening pin 420 There was a problem that (420) fell out.

On the other hand, as shown in Figure 1, the conventional vehicle seat belt pressure relief device forms a ring 190 to be fixedly installed at an appropriate position of the vehicle.

However, the ring 190 used in the conventional device is formed to extend in a plate shape from the lower case 140 constituting the body, and it is difficult to install the device using the ring 190 depending on the type of vehicle. There was a problem.

In other words, in general, the shape of the belt guide for a vehicle may be different depending on the shape of the vehicle, but the size of the ring 190 extended in the fixed plate shape is large and thick, so it is difficult to assemble the pressure relief device to the belt guide. .

In addition, since the plate-shaped bar forming the ring 190 is a fixed form integral with the lower case 140 of the body and cannot move at all, the seat belt is inserted into the device to fix it, and then the ring 190 is fixed. There was a lot of inconvenience in use, such as having to move up to the body 100 to be coupled to the vehicle belt guide (G).
