Description

Seat belt

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat belt, and more particularly, to a seat belt on which a belt for protecting a user's impact is installed due to an external shock or accident when the vehicle is loaded.

Generally, a seat of a vehicle is provided with a seat belt for protecting a passenger when colliding or sudden stopping. This is to prevent the passenger from bumping out of the car or out of the seat, that is, out of the seat, or colliding against the front window due to shock or inertia at the time of collision, thereby preventing the passenger's body from being damaged.

These belts need to be worn for the user, but it can be somewhat difficult for elderly people or children to wear seat belts. Also frequent wins. A light out going in or out of a bus that gets off the car may be a bit uncomfortable for users to repeat wearing and not wearing the belt.

Also, in case of an accident involving a multi-passenger vehicle (bus or van), the damage is large and the measures to cope with it are not well-equipped. Therefore, a system for preventing an accident is absolutely necessary.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a seat belt capable of preventing large-scale accidents in advance and providing convenience to passengers and traffic disadvantages in order to solve the above-mentioned problems.

According to an aspect of the present invention, there is provided a seat comprising: a seat including a pressure sensor for sensing a seat of a user; A main body installed on both sides of the seat; A swing arm installed to be rotatable in association with the main body; A belt installed inside the main body and wound on a belt reel; And a guide rail for moving the end of the belt to an end of the swing arm at a point where the main body and the swing arm are connected to each other. The combined swing arms are disposed on both sides of the seat, and a first buckle and a second buckle, which are fastenable to each other, may be installed at each end of the belt.

A cylinder is installed in the main body. The swing arm is formed with a curved guide groove. The swing arm can be rotated while the end of the rod sliding on the cylinder moves along the guide groove.

The guide rail includes a rack having a thread formed along its longitudinal direction, a pinion coupled to a motor at an end of the belt, and a belt unrolled along a rack by a pinion driven by a motor, As shown in FIG.

The swing arm may include a rail curtain at one side and a guide pin connected to the motor to slide the rail curtain so that a rail installed therein is not visible.

When the first buckle and the second buckle are fastened, a tension is formed and can be guided to the body side of the user.

According to the seat belt of the present invention as described above, the safety device can be easily used due to the automated system for children, the elderly, and the traffic aids.

In addition, because of the automated system, it is not only prevented from being interrupted by the obligation to install, but also has the effect of protecting the passenger in situations of rapid acceleration, rapid deceleration, rapid braking, and vehicle rotation.

FIG. 4 is a view showing an operation structure of the seat belt shown in FIG. 1, and FIG. 5 is a view showing a structure in which a cylinder is coupled to the inside of the seat belt shown in FIG.

1 to 5, a seat belt according to an embodiment of the present invention includes a seat 100, a main body 200, a swing arm 300, a belt 400, and a guide rail 500 .

The seat 100 may be fixed to the inside of the vehicle or may be slidable by the user, and the seat 100 is seated by the user. The seat 100 is provided with a pressure sensor S for detecting the seat of the user.

The main body 200 is installed on both sides of the seat 100. Here, both sides can also be used for a user to grasp when the user is seated on the seat 100. In addition, a cylinder 210 may be installed in the main body.

The swing arm 300 is coupled with the main body 200 to be rotatable. A pin 330 may be inserted at an intermediate point, that is, a connecting point, so that the swing arm 300 and the main body 200 can be engaged with each other. The swing arm 300 coupled to the main body 200 is disposed on both sides of the seat 100 so that the ends of the swing arm 300 can approach each other when the swing arm 300 rotates. The swing arm 300 is formed with a curved guide groove 310. The swing arm 300 is provided with a guide groove 310 in which the end of the rod 212 sliding on the cylinder 210 moves along the guide groove 310, (300) can be performed. In addition, the swing arm 300 may include a rail curtain 320 installed on one side of the swing arm 300 so that the equipment installed therein is not visible. In addition, the rail curtain 320 may include a guide pin 330 connected to the motor M so that the rail curtain 320 slides.

The belt 400 is installed inside the main body 200. And the belt 400 may be wound on the belt reel 410, withdrawn, or wound inward. At both ends of the belt 400, a first buckle 420 and a second buckle are provided on one side and the other side, respectively, so that they can be fastened to each other. When the first buckle 420 and the second buckle 430 are fastened to each other, a tensile force is formed and can be guided to the body side of the user.

The guide rail 500 moves the end of the belt 400 to the end of the swing arm 300 at a point where the main body 200 and the swing arm 300 are connected. The guide rail 500 includes a rack 510 having a thread formed along the longitudinal direction and a pinion 520 coupled to the motor M at the end of the belt 400. The belt 400 may be unrolled along a rack 510 such as the pinion 520 driven by the motor M and may be moved to the end of the swing arm 300.

In the seat belt 400 according to the present invention as described above, when the user sits on the seat 100 and operates the seat belt 400, the work is performed in the following order.

When the user sits on the seat 100, the pressure sensor S or the detection sensor S senses whether or not the passenger is seated in the seat 100.

The swing arm 300 connected to the main body 200 installed on both sides of the seat 100 is operated by the cylinder 210. At this time, the swing arms 300 installed on both sides are rotated to face each other.

The first buckle 420 and the second buckle 430 provided at the ends of the both side belts 400 are coupled to the end of the swing arm 300 when the swing arm 300 approaches .

When the first buckle 420 and the second buckle 430 are engaged with each other, the belt 400 is brought into close contact with the user by using a tension force due to the locking force. The point of close contact is moved to the connection point between the main body 200 and the swing arm 300.

The above-described steps are operated when the user seated on the seat 100. When the seat 100 is seated, the operation is performed in the following order.

The fastening of the first buckle 420 and the second buckle 430 is released and the buckle 420 is seated on the side of the swing arm 300 by the locking force of the belt 400. That is, the belt 400 is inserted into the connection point between the main body 200 and the swing arm 300.

When the belt 400 moves to the connection point, the motor M is operated to move to the basic positions of the first buckle 420 and the second buckle 430. Here, the base position refers to the end of the swing arm 300.

The rail curtain 320 connected to the guide pin 330 can prevent the guide rails 500 as well as various devices from being exposed to the outside. The guide pin 330 is connected to the motor M and is operated by the motor M.

Next, when the first buckle 420 and the second buckle 430 reach the end of the swing arm 300, the motor M is stopped and all operations are stopped.

Accordingly, the seat belt according to the present invention has an effect that the safety device, that is, the belt 400 can be easily worn due to the automated system for children, the elderly, the traffic aids, and the like.

In addition, because of the automated system, it is not only prevented from being interrupted by the obligation to install, but also has the effect of protecting the user in situations such as rapid acceleration, rapid deceleration, rapid braking, and vehicle rotation.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
