Abstract

PROBLEM TO BE SOLVED: To provide a cushion wherein the height of a backrest section relative to a seat section can be adjusted easily. SOLUTION: A seat section 5 and a brackets section 6 are connected through a connecting section 7 and the backrest section 6 can be raised from or turned down to the seat section 5 about the connecting section 7. The connecting section 7 is in the form of a sheet having a prescribed width and can be bent about a central section 10. The connecting section 7 is provided with engaging members 11 comprising hooks, Velcro tapes, or the like positioned at six places symmetrical about the central section 10 so that, when bent, the connecting section 7 may be kept in the bent state. When the connecting section 7 is stretched, the height of the backrest section 6 relative to the seat section can be elevated, while when the connecting section 7 is bent and the bent state is kept by the engaging members 11, the height of the backrest section 6 relative to the seat section can be lowered.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushion body that is used along a chair, for example, in which a seat portion and a backrest portion are continuously provided via a continuous portion, and the backrest portion is attached to the seat portion. Regarding things that can be tilted freely.

2. Description of the Related Art Conventionally, as shown in FIG. 3, a cushion body 1 of this type has a constant backrest portion 2 from a seat portion 3, and the height of the backrest portion 2 depends on the height of the sitting person. If a person with a low sitting height uses a cushion body with a size suitable for a person with a high sitting height, the cushion body is located above the head, which is annoying for some people. When a person with a high sitting height uses a cushion body having a size suitable for a person with a low sitting height, there is a problem that the cushion body is too low to sufficiently receive the back. In particular, a cushion body that has a plurality of vibrators built into its backrest as shown in Japanese Utility Model Laid-Open No. 63-75259 so that the shoulders and the back can be massaged is optimal depending on the seat height. I couldn't give a comfortable massage because the vibrator wasn't there.

SUMMARY OF THE INVENTION An object of the present invention is to obtain a cushion body in which the height of the backrest can be easily adjusted according to the sitting height of the user.

According to the present invention, there is provided a cushion body in which a seat portion and a backrest portion are continuously provided via a continuous portion, and the backrest portion can be raised and lowered with respect to the seat portion. The installation portion is bendable, and the continuous installation portion can be selectively held in an extended state and a bent state. By such means, the height of the backrest portion with respect to the seat portion can be increased by extending the continuous portion, and the height of the backrest portion with respect to the seat portion can be increased by bending the continuous portion. Can be lowered. Further, in the cushion body having the vibrator built in the backrest portion, the vibrator can be positioned and massaged at the optimum position by extending or bending the continuous portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS.
It will be described based on. Reference numeral 4 denotes a cushion body, in which a seat portion 5 and a backrest portion 6 are continuously provided via a continuous portion 7, and the backrest portion 6 can be tilted up and down with respect to the continuous portion 7 as a center. There is. The seat portion 5 and the backrest portion 6 are covered with an outer cloth 8 having a pattern as shown in the figure, and a cushioning material made of flexible polyurethane foam or the like is included inside. The backrest portion 6 is provided with a band 9 that is tied to the chair so as not to slip when it is used along the chair. As shown in FIG. 1, the continuous portion 7 is in the form of a sheet having a predetermined width in the vertical direction, and can be bent around a central portion 10 in the vertical width direction. Then, in order to maintain the bent state when bent, engaging members 11 such as hooks and magic fasteners are provided at three positions vertically symmetrical with respect to the central portion 10. Therefore,
If the continuous portion 7 is extended without being bent as shown in FIG. 1, the height of the backrest portion 6 with respect to the seat portion 5 can be increased, while the continuous portion 7 is bent as shown in FIG. If the engagement member 11 maintains this state, the height of the backrest portion 6 with respect to the seat portion 5 can be reduced. Therefore, when used by a person with a high sitting height, the continuous portion 7 is extended and used as shown in FIG.
When used by a person with a low sitting height, as shown in FIG.
By bending and using, you can make a cushion that fits your body. In the above embodiment, the case where only the cushion material is built in the backrest portion 6 has been shown, but as shown by the dotted line in FIG. 1, a plurality of vibrators 12 are provided at positions corresponding to the neck muscles, both shoulders and waist. Can be built in. In this case, by extending or bending the continuous portion 7, the position of the vibrator 12 can be adjusted according to the height of the seat height, and the vibrator can be positioned at an optimum position to perform a comfortable massage. .

According to the present invention, the height of the backrest portion with respect to the seat portion can be adjusted by a simple operation such as bending and extending the continuous portion, regardless of the height of the seat. Can be easily cushioned to fit the body. Particularly, in the case where the backrest has a built-in vibrator, the position of the vibrator can be adjusted, and the vibrator can be positioned at an optimum position to provide a comfortable massage.
