Description

[Detailed Description of the Invention] [Industrial Field of Use] This invention relates to cushion materials such as sheets, and particularly relates to cushion materials such as sheets made by compressing and hardening slab urethane chips.

[Prior Art] Fig. 5 shows a conventional cushion material made by compressing and hardening slab urethane chips.

In the figure, 1 is a cushion material such as a sheet, which is made by compressing countless slab urethane chips 1a, 1a, etc., which are generated when cutting and molding slab urethane chips, using a press or the like. Each slab urethane chip is assembled by solidifying each other with an adhesive or the like, and the whole is formed into a substantially flat plate shape. A sheet is formed by covering this cushion material 1 with a sheet skin material.

[Problems to be solved by the invention] According to the above-mentioned conventional cushion material, since it is formed into a substantially flat plate shape, its surface is flat.
Even if the seat is covered with a skin material, it is not possible to obtain a seat that provides a sense of stability when sitting.

This idea was made to solve the above problems, and even if the cushion material is made by compressing and hardening slab urethane chips, it can create a seat that feels stable when sitting on it. The purpose is to obtain.

[Means for Solving the Problems] In the cushion material of this invention, a predetermined portion of a substantially flat cushion material is wrapped with a band-like or string-like wrapping member to form irregularities on the surface of the cushion material that provide seating stability.

[Operation] On the surface side of the cushion material, unevenness is formed between the part wrapped with the wrapping member and the part not wrapped.

[Embodiments of the invention] Hereinafter, embodiments of the invention will be described based on FIGS. 1 to 4 of the drawings. Incidentally, the same parts as in the conventional example shown in FIG. 5 are given the same reference numerals, and the explanation thereof will be omitted.

FIG. 1 shows a first embodiment, in which 1
A is the cushion material of this embodiment, and this is made by wrapping a band material 2 as a wrapping member around the central portion of the cushion material 1 from the front side to the rear side.
As a result, the main part 3 around which the strip 2 is wrapped, and the main part 3 and the sleeve parts 4, 4 on both sides.
It is divided into sections.

According to the cushion material 1A of this embodiment, the main portion 3 and the sleeve portions 4, 4 are provided on the front side of the cushion material 1.
Since the unevenness is formed by the ridges and grooves, it is possible to construct a seat that provides a sense of stability when sitting on it.

Next, a second embodiment of the present invention is shown in FIG.
In the figure, 1B indicates the cushion material of this embodiment, which is the cushion material 1A of the first embodiment.
A cord material 5, which is a wrapping member narrower than the band material 2, is wound around both sides of the belt slightly toward the rear side.

According to this embodiment, the string material 5 can be recessed on the surface side of the cushion material 1A to partition the front side and the rear side of the cushion material 1A, and furthermore, the cushion material 1B with an excellent holding feeling can be obtained. It will be done.

3 and 4 show a third embodiment of the present invention, and in each figure, 1C indicates the cushion material of this embodiment. This cushion material 1C is wrapped with a band material 2 as in the first embodiment, and extends in the width direction of the main portion 3 at a portion near the rear side of the cushion material 1 in the surface portion that will become the main portion 3. , and a notch 6 communicating from the front side to the back side is formed, and the band material 2 is inserted through this notch 6 and wrapped around it. That is,
The first strip 2 is wrapped around the notch 6 from the front side of the cushion material 1 corresponding to the main section 3, and the second strip 2 is wrapped around the notch 6 from the rear side of the cushion material 1 corresponding to the main section 3. It is wrapped around the cloth. Reference numeral 7 denotes stopper portions that fasten both ends of the strip material 2 with magic tape or the like.

According to this embodiment, only in the portion corresponding to the main portion 3 of the cushion material 1, the front side and the rear side are recessed and partitioned by the notch 6, and the side sleeve portions 4, 4 Since the portion remains raised, a cushion material 1C having a better grip on the side side than the cushion material 1B of the second embodiment can be obtained.

[Effects of the invention] As explained above, according to the cushion material of the present invention, a predetermined portion of the substantially flat cushion material is wrapped with a band-like or string-like wrapping member, and unevenness is formed on the surface of the cushion material to provide seating stability. , it is possible to obtain a cushion material that can form a seat that provides a sense of stability when sitting on it.
