Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an air bag for a seat provided in a footrest space between front and rear seats of an automobile.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, for example, as shown in FIGS. 7 and 8, a closing member that fills a footrest space 50 between a front seat 60 and a rear seat 61 of an automobile is not provided. is there. This air bag comprises a base 51 and a pair of legs 52 provided before and after (left and right in FIG. 8). The base 51 and the legs 52 each include a plurality of air chambers 53. I have. At the time of use, as shown in FIG.
It is bent downward with respect to 51, and in this bent state, the footrest space 50
To fill the same space 50.

Here, when the cushion is to be placed on the pedestal 51, it is conceivable to fix the cushion on the pedestal 51 by passing the string attached to the cushion through an air bag and tying it. A hole for passing air through the air bag cannot be formed inadvertently.

In addition, by arranging the blocking member in this way, the rear seat can be used widely, and it is possible to extend the legs and relax, or to allow children to play, but since there is no footrest space, there is no space between the driver's seat and the passenger seat. It becomes easy to jump out of the gap to the front.

SUMMARY OF THE INVENTION The present invention provides an air bag for an automobile seat in which a strap of a cushion can be attached and a person or an object in a rear seat does not jump out to a front seat side from between left and right seats. Things.

[Means for solving the problem]

In order to achieve the above object, in the present invention, there is provided an automobile having four or more air chambers formed by a pair of front and back sheet materials, and comprising a pair of closing members and a base connecting both ends of the closing members. In a seat airbag for a vehicle for closing a footrest space between front and rear seats, a communication portion is formed at a corner where the four air chambers are in contact with each other so that the air chambers communicate with each other. In addition to forming a fixing portion to which a pair of sheet materials are fixed, a hole forming portion is formed in the fixing portion, and a thin cut portion for cutting and penetrating a through hole is formed in the hole forming portion. On the other hand, a guard member made of an air bag for closing the gap between the backrests of the left and right seats of the automobile is provided on the closing member or the base.

[Action]

Therefore, according to the present invention, when forming a hole through which the string is formed, the hole is formed in the hole forming portion of the fixing portion. When the hole forming part is pressed with a finger or the like, a part of the hole forming part is cut off at a thin cutting part to form a hole. In addition, the guard member is arranged between the backrests of the left and right seats of the vehicle, so that a person or an object does not fly forward from the gap between the front seats from the rear seat side.

〔Example〕

Hereinafter, an embodiment in which the present invention is embodied in a guard for preventing a seat user from falling down in an automobile will be described with reference to FIGS.

As shown in FIGS. 1 and 2, the closing member 1 is a member 2 for the right seat.
And a member 3 for the left seat and a member 4 for the middle seat.

Each of the right-seat member 2 and the left-seat member 3 includes a base 5 and a pair of legs 6 provided before and after the base. The leg 6 can be bent up and down with respect to the base 5.

The middle seat member 4 includes a base 7 and legs 8 provided at a rear portion (a lower portion in FIG. 2). The legs 8 can be bent up and down with respect to the base 7. The left end of the right seat member 2 and the right end of the middle seat member 4, and the right end of the left seat member 3 and the left end of the middle seat member 4 are respectively connected.

A guard member 10 is connected to a front portion of the middle seat member 4 and can be bent up and down with respect to the base portion 7.

Each of the right seat member 2, the left seat member 3, the middle seat member 4 and the guard member 10 is formed by gathering a plurality of square air chambers 16 each having a pair of front and back sheet materials S. As shown in FIG. 5, each air chamber 16 and the adjacent air chamber 16 communicate with each other at the corners where they come into contact with each other.
A circular fixing portion 19 is formed in the communication portion 17 where the corners of the four air chambers 16 are in contact with each other by welding the pair of sheet materials S. This fixed part
Reference numeral 19 denotes a hole forming portion R which can form the through hole 20, and a thin cut portion 15 is provided in the hole forming portion R in an annular shape.

As shown in FIG. 1, each of the right seat member 2, the left seat member 3, the middle seat member 4 and the guard member 10 is provided with one air inlet 18 for each member. Air can be injected into each of 3, 4, and 10 from the injection port 18.

By the way, at the time of using the above-mentioned fall prevention guard, each member 2,3,
Air is injected into the injection ports 4 and 10 respectively. Next, in the hole forming portions R of the right seat member 2 and the left seat member 3, every other cut portion 15 is cut in the left-right direction to form a through hole 20. Then, the cushion 2 is placed on the bases 5 and 7 of the closing member 1.
Place 1 A pair of cords 22a, 22b, 23a, 23b, 24a, 24b are attached to the back surface of both left and right portions of the cushion 21 at fixed intervals. This string 22a, 22b, 23a, 23b, 24
The cushion 21 is fixed to the closing member 1 by passing a, 24b through the through hole 20 to the back side of the closing member 1 and tying the corresponding strings 22a, 22b, 23a, 23b, 24a, 24b to each other.

Further, as shown in FIG. 6, both the leg portions 6 of the right seat member 2 and the left seat member 3 and the leg portions 8 of the middle seat member 4 are respectively bent downward, and in this bent state, the closing member is closed. 1 is inserted into the footrest space 26 of the rear seat 25 to fill the space 26.
The guard member 10 is bent upward to close the gap between the backrests 31 of the driver's seat 27 and the passenger's seat 28, and the strings 11 are supported by the headrests 29 of the driver's seat 27 and the passenger's seat 28, respectively.
The guard member 10 is fixed by being hooked on 30.

If a child or the like is placed on the rear seat 25 and the fall prevention guard of this embodiment is used, the gap between the backrest portions 31 of the driver's seat 27 and the passenger seat 28 is closed by the guard member 10, so that There is no danger of the infant falling down forward, and it is safe.

In this embodiment, the cut portion 15 is cut along the cut portion 15 by simply pressing the cut portion 15 with a finger, and the through hole 20 is formed in the hole forming portion R.
The cushion can be formed as in the case of the present embodiment.
When fixing the strap 21 with the straps 22a, 22b, 23a, 23b, 24a, and 24b, the through holes 20 through which the straps 22a, 22b, 23a, 23b, 24a, and 24b pass can be easily formed.

In use, when air is injected into the right seat member 2, the left seat member 3, the middle seat member 4, and the guard member 10, the communicating portion is used.
Since the fixing portion 19 is formed at substantially the center of the air chamber 16, the vicinity of the fixing portion 19 of the communication portion 17 is not crushed even if each air chamber 16 expands, and the communication portion 17 always keeps the air flow between the air chambers 16. It is a passage, and when air is injected into each of the members 2, 3, 4, and 10, air can be injected smoothly. Therefore, the air can be smoothly injected into the multiple air chambers 16 from one air injection port 18.

In addition, this invention is not limited to the said Example, It can materialize in a floating bag, an air mat, etc.

[Effect of the invention]

As described in detail above, in the present invention, the hole forming portion is cut at the cutting portion to easily form the through hole, so that the hole for passing the string can be easily formed. Also, it is possible to prevent a person or an object from jumping from the rear seat side to the front seat side.
