DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.

In FIGS. 1 and 2, this is a rectangular backrest, which is covered with a cover 1 of fabric, leather or the like. As shown in FIG. 3, this backrest is combined with the seat 2 of the vehicle so that the backrest leans against the backrest.

As shown in FIG. 4, this backrest has a plastic body 3. The main body 3 is made of expanded polypropylene or expanded polyethylene and has a size such that it can lean against the back. Further, a large number of protrusions 4 are integrally molded on the front surface of the main body 3, and the height direction X of the main body 3 is
And are arranged in the horizontal direction Y. The protrusion 4 is also made of plastic and is made of expanded polypropylene or expanded polyethylene.

As shown in FIG. 5, the main body 3 and the protrusions 4 are covered with a cover 1 made of fabric, leather or the like. The protrusion 4 is of a round shape and its height H is 20 m.
m, and the diameter D1 is 40 mm. Further, a large number of ventilation holes 5 are formed between the protrusions 3. The vent hole 5 is a round hole that penetrates the body 3 and has a diameter D2 of 20.
mm.

Further, in this embodiment, a waist pillow 6 of a certain size is provided on the back surface of the main body 3 and covered with the cover 1 at a height position corresponding to the waist of the user. The waist pillow 6 is made of a bag filled with pipe-shaped chips, buckle or chaff, and is sewn to the cover 1. Further, a belt 7 made of fabric, leather or the like is provided on the back surface of the cover 1. The belt 7 is wrapped around the seat 2 of the car to fix the backrest.

Therefore, this backrest is used for the car seat 2
In combination with the above, when sitting on the seat 2 and leaning against the backrest, the projections 4 on the backrest provide acupressure and massage effects, and the shoulders, the back and the waist are loosened and blood circulation is improved. Therefore, stiff shoulders and low back pain can be softened and treated only by sitting, and stiff shoulders and low back pain can be naturally softened and treated while sitting on the seat 2. Acupressure and massage also have a cosmetic effect.

Further, with respect to this backrest, when it leans against the backrest, a space is formed between the respective projections 4, and the air permeability is obtained by the space. Further, the ventilation holes 5 improve the ventilation and remove the moisture. Moreover, since the back is supported by the protrusions 4, the contact area between the back and the back is small, and the user can lean back comfortably.

The body 3 and the protrusions 4 are made of expanded polypropylene or expanded polyethylene, and the expanded polypropylene and expanded polyethylene have appropriate strength and elasticity. Therefore, it is possible to impart appropriate strength and elasticity to the protrusions 4 and enhance the acupressure and massage effects. The bulkiness of the backrest is not impaired. It is also possible to reduce the weight of the backrest by using expanded polypropylene or expanded polyethylene.

Furthermore, when leaning against this backrest,
The body 3 is supported by the seat 2 and the waist pillow 6,
The body 3 curves along the user's back and waist. Therefore, the protrusion 4 can be pressed against the back and the waist to effectively treat stiff shoulders and low back pain.

Not only the seat 2 of the car, but also the backrest can be combined with a home sofa to sit on the home sofa and lean on the backrest. This backrest can be paired with an office chair or with other chairs. Further, in this embodiment, the backrest having the round protrusions 4 has been described, but the protrusions 4 do not necessarily have to be round shapes, and may have other shapes.
