Description

Safety devices for automobiles

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a vehicle, and more particularly, to a safety device for a vehicle for protecting a passenger in a rear seat in a crash and a collision accident.

Generally, an automobile safety device is provided with an airbag or the like in order to protect a rider on a driver's side and a passenger's seat in the event of a collision or a collision. The above-mentioned airbag protects the occupant from impact, thereby minimizing the damage caused by the accident.

And the most basic safeguard is the safety belt. Unlike the above-described airbag, the seatbelt is also installed in the rear seat so as to protect the passenger in the rear seat

However, in the case of a passenger who rides in the back seat, if the seat belt is forgotten to be worn, the damage to the collision and collision accidents becomes extremely large.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a safeguard apparatus for an automobile which assures the safety of a rider in a rear seat when a collision or a collision occurs.

In order to achieve the object of the present invention, there is provided a vehicle occupant restraint system, comprising: a vehicle occupant restraining member mounted transversely to a roof panel of a vehicle to descend downward in a collision or a collision to prevent a rider of a rear seat from departing;

And a passenger departure preventing member moving means which is mounted on one side of the center pillar and moves the above-mentioned passenger departure preventing member instantaneously downward.

FIG. 7 is a side view showing a completed operation state according to the present invention; FIG.

FIG. 8 is a plan view showing an operation completed state according to the present invention; FIG.

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

FIG. 1 is a perspective view showing an embodiment according to the present invention, showing a vehicle body 1 and a vehicle occupant separation preventing member 3. FIG.

The above-mentioned vehicle occupant separation preventing member 3 has a structure in which the front end portion is fixedly coupled to the roof inner panel 5. [ The front end of the support arm 7 is fixed to both ends of the support arm 7 and the other end of the support arm 7 is moved to the center pillar 9 And is fixed to the member (11).

It is preferable that the above-mentioned passenger separation preventing member 3 is made of a flexible and foldable material.

2, the movable member 11 is provided with a guide groove 13 in the vertical direction inside the center pillar 9 and inserted in the guide groove 13 to be slidable . The moving member 11 has a predetermined chamber 15 formed between the upper end portion of the guide groove 13 and the moving portion in an unactuated state and the gunpowder 17 is inserted into the chamber 15. Then, an ignition device 19 is inserted into the curing agent 17 and connected to an impact detection device (not shown) such as an airbag.

The above-described impact sensing device may be a conventional one used in an airbag or the like in the present embodiment.

At the lower end of the guide groove 13, an impact absorbing member 21 is interposed. The impact absorbing member 21 interposes the elastic member capable of absorbing the impact while blocking the movement of the movable member.

The shock absorbing member 21 may also be made of a rubber material and should have a good elastic force.

FIG. 3 is a cross-sectional view of the A-A portion of FIG. 2, showing the center pillar 9, the guide groove 13, the moving member 11 and the support arm 7.

FIG. 4 is a view showing a roof panel according to an embodiment of the present invention, in which the ride-away preventing member 3 is disposed inside the loop inner trim 23.

FIG. 5 is a detail view showing part A of FIG. 4 in detail, in which the loop inner trim 23 shows the cutout groove 25 formed in the transverse direction of the vehicle body.

The incision groove 25 is for cutting the incision groove 25 of the roof inner trim 23 to operate quickly when the occupant release preventing member 3 instantaneously descends downward.

6 shows a side view book showing the embodiment according to the present invention, an occupant release preventing member 3 before operation, a support arm 7, a moving member 11 and a guide rail 13. The above-described vehicle occupant separation preventing member 3 is stored so as to overlap the roof panel 5 side as described above.

When a collision or a collision accident occurs in the automobile, the impact is detected by the separately formed impact detection device, and when the impact is detected, the ignition device 19 detonates the explosive 17 by the ignition device 19 . Then, the moving member 11 is moved downward along the guide groove 13 by the explosive force. At this time, the moving member 11 and the fixed support arm 7 are simultaneously moved downward to move the vehicle occupant separation preventing member 3 downward as well. If the passenger departure prevention member 3 is disposed inside the loop inner trim 23, the incision groove 25 is cut downward while being cut.

7 and 8 show a state after the operation, in which the rider hits the rider departure prevention member. The above-mentioned rider departure prevention member 3 is made of a strong and soft fiber material, Thereby preventing the protrusion.

On the other hand, as shown in Fig. 8, the support arm 7 is preferably disposed as close as possible to both sides of the vehicle cabin, and the support arm 7 is minimized as long as its length is allowed within the design range . The supporting arm 7 is formed so as to protrude in the horizontal direction as shown in FIG. 1, but the supporting arm 7 is simply connected to the moving member 11 And it is also preferable that the end portion is curved in consideration of the safety of the rider in design. The material is also made of elastic rubber so as to ensure the safety of the rider. Therefore, the support arm 7 can be disposed adjacent to both sides of the interior of the vehicle so as to reduce the impact on the rider, and the impact applied to the rider can be minimized according to the size, shape and material of the support arm.

The safety device for an automobile according to the present invention can prevent the passenger of the rear seat from being detached to the front side in the event of a collision or a collision, thereby reducing damage and securing safety.
