Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side support having a built-in side airbag device for a vehicle seat.

[0002]

2. Description of the Related Art It is known that an airbag device is incorporated in a side of a vehicle body in a seat back of an automobile seat to protect an occupant by deploying the airbag in a side collision.

A side support separate from the seat back is provided on the side of the rear seat on the side of the vehicle body, and an air bag device incorporated in the side support is further increased by the side support and the air bag when a side collision occurs. The occupants can be protected.

[0004] All of the above airbag devices are housed in a metal open-topped storage body, which is embedded in a foam pad and formed separately from a frame that supports the pad. I have.

[0005]

Therefore, in the above-mentioned conventional product, it is necessary to house the airbag device in a dedicated metal housing, and embed and fix the housing in a pad.

[0006] Therefore, not only the structure becomes complicated, but also troubles are required in incorporating the airbag device.

Accordingly, an object of the present invention is to eliminate the disadvantages of the conventional product in a side support in which the protection of an occupant during a side collision is ensured.

[0008]

A side support according to the present invention for achieving the above object comprises a substantially U-shaped frame having an upper open portion which is fastened to a vehicle body side.
The frame comprises a foam pad covered with an outer skin by closing an opening, and the side airbag device is housed in the frame.

[0009] With the above configuration, a special storage body for storing the airbag is not required, so that the structure of the side support is simplified.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a rear seat with a side support (A) according to the present invention, wherein (SB) is the seat back, (SC) is the seat cushion,
(B) shows the side support of the seat cushion (SC).

The side support (A) is a seat back (S)
B) is disposed along the side of the vehicle body, and the seat back (S
It is formed separately from B). The side support (A) is fastened to the vehicle body, and a frame (1) is provided inside.

As shown in FIGS. 2 and 3, the frame (1) has a U-shape with an open top and both ends closed, and is formed of a metal plate in a substantially long box shape.

The interior of the frame (1) is vertically divided by a reinforcing plate (10), the upper side of which is a storage section (1A) for the airbag device (4), and the lower side is a buffer section (1B). .

An air bag device (4) for side collision is stored in the storage portion (1A), and the air bag device (4) is provided.
Is fixed by a fastening member (40) such as a bolt inserted from the bottom of the frame (1).

A flexible support member (13) formed by bending a wire protrudes above the storage portion (1A), and a side support (A) formed of a foam pad (not shown) supported by the flexible support member (13). The cushioning property at the upper part (A ₁ ) is good.

The buffer portion (1B) has a large number of through holes (15)... As shown in the figure, and is configured to absorb a shock by deforming when a side collision occurs.

An upper leg (11) is formed from an L-shaped metal piece on the upper bottom of the frame (1), and a wire is U-shaped on the lower bottom.
Each of the lower leg portions (12) bent in a letter shape is welded,
In addition, the lower legs (11) and (12) are fastened to the vehicle body side by bolts or the like.

A pad made of foam (2) is adhered to the outer side wall of the frame (1) so as to cover the opening of the frame (1), and the storage portion (1A) of the pad (2) is closed.
A slit (20) is provided in a portion located at a position (2) so that the airbag of the airbag device (4) can be deployed outward.

Further, a skin (3) for covering the pad (2)
Is composed of an inner skin (30) and an outer skin (31), and a joining point (3) of the two skins (30) and (31) is formed.
A) covers the pad (2) so as to be above the slit (20).

In the figures, (14)... Indicate epidermis (30) (3)
1) Fixing piece for terminal binding, (32) is epidermis (30)
The binding device for binding the terminal of (31) to the fixing piece is shown.

[0021]

According to the present invention, since the frame can serve as a housing for the airbag device, there is no need to provide the housing for the airbag device separately from the frame as in the prior art.
Therefore, the structure is simplified, and the assembling work of the airbag device can be facilitated.
