Description

[Detailed description of the invention] The present invention relates to an improvement of a seat bank pad for a rear seat of an automobile.It is easy to position the seat bank pad against the seat bank frame, which can be damaged during assembly work, and can be easily positioned against the seat bank frame, which may be displaced when covered with an outer skin or the like. It is lightweight, has good cushioning properties, and has a good external shape when completed.
The purpose is to provide a seat bank pad that can be manufactured at a relatively low cost.

Automobiles, which are supplied at relatively low prices, are required to reduce costs and weight, and it is not possible to increase the thickness of the seats, so using a so-called molded band is necessary to improve cushioning properties. However, in order to improve the cushioning properties and satisfy the objectives of low cost and light weight, a pad A made of flexible synthetic resin foam in the form of a slab was used as shown in Fig. 5. However, in the case of a sheet bank, as shown in Fig. 6, there is no locking part, so positioning with respect to the sheet bank frame B becomes unstable, and when enclosing with the outer skin C etc. The position of the band A is shifted, and the edge of the sheet bank frame B protrudes, which not only poses a danger, but also has disadvantages such as poor external appearance and extremely poor workability.

The present invention provides a seat bank pad that does not have the above-mentioned drawbacks by adopting the configuration described in the claims of the utility model registration.

The configurations of the two illustrated examples will be explained below.

FIG. 1 is a perspective view showing the seat bank band in the left half of the split type seat bank in the rear seat, and the main pad 1 is a slab of flexible synthetic resin foam such as polyurethane foam. A large number of protrusions 2 are formed on the back side, the width of which corresponds to the main part of one of the divided sheet banks, and at least the left and right sides 3, 4 and the top end of the protrusion 20. As a result, it is engaged with and abutted on a seat bank frame 5, which will be described later.

On both left and right sides 3 and 4 of the main pad 1 mentioned above, there are first corner pads formed in the shape of long plates made of synthetic resin foam that is slightly harder than the synthetic resin foam that constitutes the main pad 1. 6.7 is in contact.

These corner pads 6.7 have an outer shape that defines the peripheral shape of the seat bank, and are bonded to the main pad 1 at a portion 9 of the contact surface near the front surface 8 of the seat bank, and The portion 11 closer to 10 is not bonded and is attached to the peripheral flange portion of the sheet bank frame 5 between the main band 1 and the first corner band 6.1, as shown in FIGS. 2 to 4. 12 is inserted into the insertion gap 13.

Further, on the rear surface 14 of the main pad 1, that is, the surface on the side of the sheet bank rear surface 10 mentioned above, a second corner pad 1 of the same quality as the pad 6.7 is provided adjacent to the corner pad 6.7.
4.15 is glued and fixed at the top end of the protrusion 20.

FIG. 2 is a cross-sectional view of an example of a completed seat back obtained by assembling a seat back pad having the same configuration as that shown in FIG. ', a second corner band 18 identical to the second corner pad 14.15 is glued 1
9 has been done.

In the embodiment shown in FIG. 2, the first corner bands 21 are in contact with both the left and right sides of the main pad 20, and are bonded at the portion 22 near the front of the seat back, and the insertion gap 13 is attached at the portion near the back of the seat bank. is formed.

Therefore, the main pad 20, the first corner band 2
The position of the seat back pad 23 consisting of the corner band 18 of 1 and i2 is determined by fitting the insertion gap 13 into the periphery 7 flange portion 12 of the seat bank frame 5, and During the wrapping operation, its position does not shift, the peripheral edge 7 flange portion 12 is always housed within the insertion gap 13 and is prevented from protruding, and the outer shape of the housed sheet bank is also closely aligned with the first corner pad 25. This will maintain an accurate external shape as defined by the

In the illustrated example, the second corner pad 18 also comes into contact with the seat back frame 5 and supports the main pad 20, so there is no possibility that a relative positional shift will occur between the seat back frame 5 and the main pad 20. When a force is applied, this force can be limited to only a partial deformation of the protrusion 16 or 260 adjacent to the pad 18.

3 and 5 show an embodiment in which a reinforcing member 27 is fixed to the seat bank frame 5 of the embodiment shown in FIG. This is a cross section at a position shifted by 17 protrusions compared to the one in FIG. I'm sure of it.

In FIGS. 2 to 4, the second corner pad 1
The protrusion 17 to which the pad 8 is bonded is compressed by the height of the pad 18 due to the contact between the pad 18 and the seat bank frame 5, and is lower in height than the other protrusions 26 and 28. , and in FIGS. 3 and 4, the protrusion 16
is pressed against the reinforcing member 27, and its height is compressed and becomes lower.

The present invention has the structure and operation described above, and the positioning of the seat bank band with respect to the seat bank frame during the seat bank assembly work is performed on the frame side in the insertion gap between the main band and the first corner pad. The fitting of the peripheral flange portion allows the work to be carried out reliably and easily, and there is no displacement during the enveloping work of the outer skin, which has the effect of making the work easy, forceful, and reliable.

Due to the presence of the enclosed corner band, the outer shape of the main pad made of a slab can be arranged in 9 predetermined ways to achieve a good outer shape, and since the main band is made of a slab-shaped synthetic resin foam, good cushioning properties can be obtained. I can,
It is also lightweight and inexpensive.
