JPH04106033U - Air bag table for vehicle seats - Google Patents

Abstract

(57) [Summary] [Purpose] An airbag table that can be installed on the back of the seat back of a vehicle seat that tilts in the front-rear direction, such as a car seat, and can be used as a table and protect rear seat occupants in the event of a vehicle collision. To always hold an air bag table horizontally even if the bag tilts. [Structure] An air bag adjustment body is provided below the main body (A) of the air bag table to maintain the table surface of the main body (A) horizontally depending on the amount of air injected.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is installed on the back side of a vehicle seat such as a car seat. It is designed to protect rear seat passengers in the event of a collision with a moving vehicle, and can also be used as a table during normal use. Regarding available airbag tables.

0002

[Conventional technology]

Conventionally, as a case of this kind, Japanese Patent Publication No. 47-29530 filed by the applicant of the present application Some are disclosed in official gazettes. This is an elastic bag that expands when air is injected, and the top surface becomes table-like. It can be used as a table during normal times, and can also be used in the event of a car collision. , the cushion body, i.e., the internal air of the airbag due to the collision of the occupant. A cushion that safely protects the occupants by releasing the air injected as it rises to the outside. It is something that performs the functions of the body.

0003

[Problem that the idea aims to solve]

Therefore, the conventional product described above maintains the top surface horizontally when air is injected into the airbag. It is configured so that the top surface can be used as a table and food containers, etc. can be placed on it. . However, since the airbag is integrated into the back of the seatback, When the seatback is tilted forward or backward, the top surface of the airbag will touch the tilting of the seatback. This caused the problem that it could not be used as a table because it was tilted. Therefore, the present invention has a simple structure and can be used as a table even when the seat back is tilted. The purpose is to make it usable.

0004

[Means to solve the problem]

Airbag table for vehicle seat according to the present invention to achieve the above objects consists of a main body made of an elastic bag that forms the table, and an air inlet provided below the main body. Consists of an airbag adjustment body that holds the table of the main unit horizontally depending on the amount of air applied. It is characterized by this.

[0005]

[Effect]

The top surface of the main body tilts as the seat back tilts, but air is injected into the adjustment body. By adjusting the amount of expansion of the adjustment body, the body can be moved up and down by the adjustment body. This allows the table surface, which is the top surface of the main body, to be held horizontally.

[0006]

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. In the drawing, (A) is on the back of the seat back (SB) of the front seat. The main body made of an elastic bag is integrated into the main body (A). Each of the adjusting bodies consisting of a bag is shown. The above main body (A) and adjustment body (B) are each formed into a bag shape from a flexible material such as rubberized cloth. By injecting air into it, it expands as shown in Figures 1 and 2. In addition, by discharging the internal air, it can be folded onto the back of the seat back (SB). It is configured so that

[0007] As mentioned above, when the main body (A) is expanded, its upper surface (a) becomes flat. Use a table cloth made of relatively soft rubber or plastic to hold the A plate (11) is integrally bonded to the flexible material (12). And this book The body (A) is equipped with a safety valve (13), and if a rear seat passenger collides with it, It is configured so that the air inside the main body (A) is released to the outside and provides a cushioning effect. There is. In addition, in the figure (14), the internal air is exhausted to the outside and the main body (A) is folded. This is a release plug for. Inside this main body (A) is a compressor (not shown) or a pump (not shown). Therefore, air is injected via the pipe (16) and check valve (15).

[0008] The above adjustment body (B) is composed of the main body (A) and a separate air bag, and the main body (A) ) is connected to the main body (A) below, and a pipe (21) is connected to the pump (not shown). Inflates by injecting air into the interior through. And this inflated adjustment The body (B) is deflated by opening the release plug (22).

[0009] Therefore, due to the expansion of the adjustment body (B), the main body (A) is pushed upward, and the main body ( The upper surface of A) moves upward. Figure 1 shows the top surface (a) of the main body (A) after reducing the amount of air injected into the adjustment body (B). Figure 2 shows the seat back (SB) folded back. In such a case, increase the amount of air injected into the regulating body (B) to inflate the regulating body (A). The upper surface (a) of the main body (A) is held horizontally by the expansion of the adjustment body (A). do.

0010 As shown in the figure, the above adjustment body (B) is attached to the seat back (S) with respect to the main body (A). B) is preferably located on the back side of the seat back. Of course, the top surface of the main body (A) can be held horizontally by tilting the bracket (SB). In the event of a car collision, the front load from the rear seat occupant is divided between the main body (A) and the adjustment body (B). This can be absorbed by two airbags, improving cushioning performance.

[0011]

[Effect of the idea]

As mentioned above, the present invention is designed so that even when the seat back is tilted, the main body that forms the table remains The surface can be kept horizontal at all times by the adjustment body. In addition, since it is only necessary to install an airbag adjustment body in the main body, the structure is simple and the cost is low. Moreover, by adjusting the amount of air injected into the control body, the The top surface can be adjusted horizontally, making it easier to operate.

FIG. 2 is a partially cutaway side view when the seat back is folded backward.
