Description

[Detailed Description of the Invention] The present invention mainly relates to a backrest of a seat arranged in an automobile or the like.

This kind of backrest is made of plastic foam,
A cushioning core material made of a fiber aggregate or the like is coated with a covering material. Conventionally, the covering material 1 is wrapped around the core material 2 once as shown in FIGS. 1 and 2, and the backrest 10 is Clip 4 the bars 3 and 3 attached to both ends of the facing material 1 on the back side of the
and the joint portion is covered with a cover 5. Here, 6 is a frame penetrated by the core material 2. However, since the clips 4 are thick, they cannot be arranged closely, and the main problems are the appearance, such as the formation of gaps between the clips 4 and the bulging of the cover 5 where the clips 4 are placed. This may cause serious problems.

The present invention aims to improve the drawbacks of the above-mentioned prior art and prevent gaps and bulges from occurring at the joints of facing materials. The material is wrapped around the core material, and a pair of plates attached to both ends of the facing material are overlapped and joined from the outside with tassels, and the joint is covered with a cover. The gist of what you did.

The present invention will be explained with reference to an embodiment shown in FIG.
It is made of natural leather or the like and is wrapped once around a cushioning core material 12 made of plastic foam, fiber aggregate, or the like. A pair of backing plates 13 made of base paper, resin felt, plastic, etc. are provided on both edges of the upholstery 11, and are overlapped on the back of the backrest 20 and fixed from the outside by a tassel 14 to join them. be done. In this case, an appropriate tension is applied to prevent wrinkles from forming on the facing material 11, but such tension can be easily adjusted by adjusting the degree to which the pair of backing plates 13 are overlapped. The joint is covered by a cover 15. 16 is a frame that passes through the core material 12.

In this invention, as described above, a pair of backing plates are installed on both ends of the facing material around which the core material is wound once, and the plates are overlapped and attached from the outside by tassels, so that When pulling the facing material, the tensile force is transmitted evenly in the width direction of the facing material by the backing plate,
Wrinkling of the facing material is completely prevented. Depending on how the boards overlap each other, appropriate tension can be easily applied to the facing material, and tackers can be easily driven in. Such tackers are thinner than clips, so they can be driven in densely. There is no need to provide a gap between the cover and the tatcher that would cause a problem in appearance, and the cover does not have a bulge that would cause a problem in appearance at the place where the tatcher is driven.

Furthermore, since the upholstery is only attached to the edge of the upholstery, the feel of the back of the backrest is not affected by the upholstery.

In addition, since the tatker is driven into a pair of overlapping backing plates, its pull-out strength is high, and since both edges of the facing material are reinforced by the pair of backing plates, the strength of the joint is strong. becomes very large.
