The present invention relates to a passenger protection device of a motor vehicle, and more particularly, to a shock absorber that can assist a passenger from colliding with a sudden movement in the traveling direction of the vehicle by an inertial force during sudden braking.

As the road condition improves and the performance of the car improves in proportion, the high speed driving of the car is becoming common.

High speed driving of the vehicle has the advantage of shortening the travel time, but increases the risk of causing a crash.

Therefore, the seat belts are mandatory to install seat belts in automobiles, but these seat belts put pressure on the wearer, and thus many people avoid wearing them.

In particular, in the case of a passenger vehicle, the rear seat occupies little of the occupant's seat belt, so when the vehicle suddenly brakes or causes a forward collision, the occupants of the rear seat collide with the front seat back.

However, since the seat must withstand a certain load and maintain a constant detective, a metal frame is installed inside the seat.

Therefore, even if the sheet is covered on the frame, the impact force causes a fatal accident if collided by inertial force.

In addition, if the vehicle crashes forward while driving, people in the driver's seat and the passenger seat will have their heads flipped back at the moment of the collision. In order to prevent such a phenomenon, a supporting member called a head rest is installed.

However, since the head redtro is installed inside the frame to maintain a constant shape, the head can be prevented from falling back, but the injury is often caused by the impact force.

The present invention is devised to solve the problems of the prior art as described above, an object of the present invention is to provide a vehicle that can absorb the impact force when the passengers collide while moving by the inertial force of the vehicle during a front collision or sudden braking To provide passenger protection.

In order to realize the above object of the present invention, a passenger protection device for a vehicle, characterized in that the shock absorbing layer is formed integrally or separated from the sheet cover at the upper end of the sheet bag of the vehicle.

The shock absorbing layer provides a passenger protection device for a vehicle, characterized in that compressed air is injected into the inside of the shell.

In addition, the shock absorbing layer provides a passenger protection device of a vehicle, characterized in that a plurality of air built in the inside of the shell.

The shock absorbing layer is provided with an air inlet to replenish air.

The shock absorbing layer is provided with opening and closing means such as a zipper so that the ball into or out of the inside.

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

FIG. 1 is a view showing a seat in a state where a passenger protection device according to the present invention is installed, and shows that the shock absorbing layer 4 is formed at the upper end of the seat bag 2.

This shock absorbing layer 4 is provided in the position where the conventional head rest is located, and has comprised the upper end part of the sheet bag 2 as a whole.

The shock absorbing layer 4 is installed to cover the front, rear and top surfaces of the sheet bag 2, which may be formed integrally with the sheet bag 2 or may be manufactured and fixed separately from the sheet bag 2. Installed in such a way.

In this case, as a means for fixing the shock absorbing layer 4 to the sheet bag 2, a string 8 is inserted into the lower end of the avoidance 6 of the shock absorbing layer 4 so that the sheet bag can be tightened (see FIG. 2). ).

The outer skin 6 may be made of natural leather or artificial leather. In order to maintain the compressed air absorbent layer 4 therein, the inner skin 10 of resin may be installed inside the outer skin 6. In this state, the endothelial 10 is fastened by tightening the string 8 in a state where it is covered on the upper portion of the sheet bag 2. Therefore, the endothelium 10 may be manufactured in a state in which a portion making contact with the sheet bag 2 forms a groove inward.

An air inlet 12 is formed at a predetermined position in order to allow air to be introduced into or taken out of the shock absorbing layer 4.

This air inlet 12 is generally of such a structure that is installed in the ball (ball) can be used, so the detailed description is omitted.

FIG. 3 is a view showing a shock absorbing layer according to another embodiment of the present invention. The layer provided on the top of the sheet bag 2 forms an air layer in the first embodiment, whereas the shell 6 It shows that a plurality of balls 14 are put inside.

For example, the ball 14 may be a ball having excellent shock absorption, such as a soft tennis ball, but not limited to only such a ball, any ball in which compressed air is injected may be used.

In this embodiment, the ball 14 is provided with an opening and closing means 16 on the outer shell 6 which can be opened and closed with a zipper or the like so as to be replaced with a new one when the compressed air is partially lost.

In addition, the shock absorbing layer (4) is better to protrude to the rear portion where people sitting in the rear seat can collide in a sudden braking, unlike the above embodiments, the shock absorbing layer is used to put a member such as a sponge It may be.

The passenger protection device of the present invention made as described above may be installed in the front seat of the vehicle or in the rear seat, and may be integrated with or separate from the sheet cover of the seat bag.

Therefore, the passenger protection device of the present invention, when the vehicle is suddenly braking while driving, the passengers are oriented in the driving direction by the driving inertia of the vehicle, in this case, especially those who ride in the rear seat hit the forehead on the back of the front seat Bumps against the shock absorbing layer 4.

At this time, the impact absorbing layer 4 of the present invention is slightly compressed by the impact force, so that the impact is substantially absorbed, so that the impact area becomes an air layer.

This can significantly reduce the impact force as compared with the conventional head rest, thus substantially preventing the impact area.

In addition, when the shock absorbing layer 4 of the present invention is formed up to the stop portion of the sheet bag 2, any part of the occupant's body can be protected, thereby preventing injury due to the impact.

Since the shock absorbing layer 4 of the first embodiment is provided with an air inlet 12, air can be supplied when air pressure is insufficient, and the shock absorbing layer of the second embodiment can be opened and closed so that the balls 14 can be exchanged. Since (16) is provided, the function of the shock absorbing layer can be preserved at all times.

In addition, the shock absorbing layer 4 of the front seat may be wounded by people wearing the seat belt during braking, the shock absorbing layer of the present embodiment can reduce the degree of injury compared to the seat with the head rest.

In addition, while the vehicle is stopped and rested, the shock absorbing layer may be used as a head restraint. However, the seat having a conventional headrest is inconvenient because its width is narrow, but the shock absorbing layer of the present invention is formed on the upper and left sides of the seat. There is also an advantage to relax.
