Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a seat cushion structure for an automobile seat, and more specifically, a foam cushion body placed on a frame, and a lower surface of the foam cushion body. The present invention relates to a sheet cushion structure comprising a sheet-like reinforcing member which is integrally molded with the foam cushion body and whose front end protrudes from the front end of the foam cushion body.

(Prior Art) This type of seat cushion structure for an automobile seat, as shown in Figs. 6 and 7, consists of a spring supporting material stretched between frame-like frames, and a foam cushion attached to the frame-like frame. The cushion body 1 is placed thereon and the cushion body 1 made of foam is covered with a skin material.

A sheet-like reinforcing member 2 is attached to the foam cushion body 1 on the side where the foam cushion body 1 is attached to the frame in order to protect the lower surface 1a of the foam cushion body 1 from the spring support material. It is integrally molded with 1.

This sheet-like reinforcing member 2 has the same width as the foam cushion body 1, and has a front end protruding beyond the foam cushion body 1 and is provided with a protruding portion 3.
This protruding portion 3 is bent toward the lower surface 1a of the foam cushion body 1 (in the direction of the arrow shown in the figure), so that a two-layer structure is formed between the frame-like frame and the foam cushion body 1.

That is, by forming the sheet-like reinforcing member 2 into two layers, the reaction force of the frame-like frame to the foam cushion body 1 is alleviated, and generation of abnormal noise due to contact with the frame or the like is prevented.

However, since the sheet-like reinforcing member 2 is integrally molded with the foam cushion body 1, an impregnated layer is formed on the sheet-like reinforcing member 2.

Therefore, when the protruding portion 3 of the sheet-like reinforcing member 2 is bent toward the lower surface 1a of the foam cushion body 1, since an impregnated layer is formed, it is difficult to bend the protruding portion 3 and the bending process takes time. Was.

Moreover, since the sheet-like reinforcing member 2 has the same width as the foam cushion body 1, when the protruding portion 3 is bent, both ends of the protruding portion 3 are exposed to the outside from the lower surface 1a of the foam cushion body 1. However, there was also a risk that the appearance quality would deteriorate.

The present invention was devised in view of these points, and its purpose is to easily bend the protruding portion of the sheet-like reinforcing member into a foam cushion body, and to improve the appearance quality. It provides a seat cushion structure.

(Means and effects for solving the problem) The seat cushion structure of the automobile seat according to the present invention includes a foam cushion body placed on a frame, and a foam cushion body mounted on the lower surface of the foam cushion body. It consists of a sheet-shaped reinforcing member that is integrally molded with the cushion body and whose front end protrudes from the front end of the foam cushion body, and the sheet-shaped reinforcing member is formed so that the width of the protruding portion is smaller than the width of the foam cushion body. It is something that

According to this sheet cushion structure, the width of the protruding portion of the sheet-like reinforcing member is smaller than the width of the foam cushion body, so when the protruding portion is folded into the foam cushion body, the protruding portion is folded. becomes easier. Further, since the width of the protruding portion is smaller than the width of the foam cushion body, the protruding portion is not exposed to the outside from the lower surface of the foam cushion body.

(Embodiment) An embodiment of the present invention will be described based on FIGS. 1 to 5.

In the figure, a foam cushion body 1 is provided with a coarse woolen felt 2 serving as a sheet-like reinforcing member on the lower surface 1a.

This coarse wool felt 2 is a foam cushion body 1.
The front end protrudes from the front end 1b of the foam cushion body 1, and a protruding portion 3 is provided.

The width of the protruding portion 3 of the coarse wool felt 2 is smaller than the width of the lower surface 1a of the foam cushion body 1.

When the protruding part 3 of the coarse wool felt 2 is bent toward the foam cushion body 1, the protruding part 3 can be easily bent because the width of the protruding part 3 is small.

Therefore, the foam cushion body 1 and the frame 5
The coarse wool felt 2 can be easily made into two layers between the gaps, and the work of bending the protruding portion 3 of the coarse wool felt 2 is easy, and the work efficiency can be improved.

In addition, since the protruding part 3 of the coarse wool felt 2 has a small width, there is no need to align the bending position when folding the protruding part 3, which eliminates the need for this work and further improves work efficiency.

Moreover, when the protruding part 3 is bent, both ends of the protruding part 3 are connected to the lower surface 1a of the foam cushion body 1.
It is not exposed to the outside, and the appearance quality is improved.

(Effect of idea) According to this invention, the following effects are produced.

Since the width of the protruding portion of the sheet-like reinforcing member is made small, the protruding portion can be easily bent toward the foam cushion body.

Since the width of the protruding part is small, when bending the protruding part, there is no need to position the bending part, which improves work efficiency.

The protruding portion is not exposed to the outside from the lower surface of the foam cushion body, and the appearance quality is improved.
