The front surface of the hard board curves outwards longitudinally and curves inwards transversely. The buffering material and filling material are fitted to the front surface of the hard board. As we rest on the board, our back sinks into the concave region of the hard board and our waist, chest and neck may be supported by the convex region, buffering material and filling material. The sudden motion of our back at the moment we sit and lie back on the board may be buffered by the filling material and buffering material. Therefore, injuries to our back and body may be avoided and discomfort may be alleviated.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention generally relates to a back supporting board. More particularly, the invention relates to a back supporting board that can buffer the sudden motion of a user's back as he sits down and that can support user's lumbar, thoracic and cervical and avoid discomfort with a hard board and a buffering material

2. Description of the Prior Art

People working in an office would purchase a backrest to support their waist and back for the purpose of comfort.

There are many types of backrest available in the market, such as the backrest mimicking the curve of human back and backrest that can be adjusted. However, they have the following drawbacks:

1. Because people have different shapes and sitting postures, the boards of the prior art can not provide enough or accurate support.

2. Foam is the main type of material used for support in the prior art. If foam is too hard, it has a limited buffering effect and a user can be injured easily. In addition, discomfort usually occurs after the user sits on such backrest for a period of time.

3. If foam is too soft, the user's back will easily sink into it. However, the user's range of motion is easily limited by the board.

4. Foam becomes less flexible after a long period of use. Therefore, the backrest of the prior art can not provide enough support and discomfort would occur (a user's back or body may sink deeply into the backrest as he sits down and lies his back on the backrest).

From the above, we can see that the backrest of the prior art have many disadvantages and need to be improved.

To eliminate the disadvantages in the prior art, the inventor has put a lot of effort into the subject and has successfully come up with the back supporting board of the present invention.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a back supporting board that can support a user's waist, chest and neck with the special shape of the board and the buffering material.

Another object of the present invention is to provide a back supporting board that can buffer the pressure from the sudden motion of a user's back at the moment he sits and lies backwards to avoid injuries to the body.

A third object of the present invention is to provide a back supporting board that the buffering material and filling material are disposed on the hard board to strengthen the support of the back.

To reach the object, the back supporting board of the present invention is disclosed. The back supporting board of the present invention comprises a hard board, a buffering material, a filling material and an enclosure portion. The hard board has a front surface. The front surface of the hard board curves outwards longitudinally and curves inwards transversely. The buffering material and filling material are fitted to the front surface of the hard board. The area not covered by the buffering material may be covered by the filling material; alternatively, the filling material and the buffering material may overlap; in addition, there are other configurations in which the filling material and the buffering material may be arranged. Last, the enclosure portion is fitted to enclose the hard board. As a user rests his back on the board, his back sinks into the concave region of thehard board1 and our waist, chest and neck may be supported by the convex region, buffering material and filling material.

Please seeFIGS. 14A and 14B, which illustrate the back supporting board of the present invention in use. First, we place the board of the present invention on thecushion51 of achair5 and the board should rest against thebackrest52 of thechair5. As we rest on the board, our back61 sinks into the concave region of thehard board1 and our waist, chest and neck may be supported by the convex region as well as thebuffering material2 and fillingmaterial3. In addition, because thehard board1 has a high degree of strength and thehard board1,buffering material2 and fillingmaterial3 can provide a high degree of support, as we rest against the board of the present invention, thebuffering material2 would become deformed so as to absorb the sudden force exerted by our back. Therefore, injuries to our body may be avoided. In addition, the small ball-like protrusions21 provided on the surface of thebuffering material2 serve the purposes of massage and stress relief as our back61 rest on the surface of thebuffering material2. Therefore, the small ball-like protrusions21 can make us more comfortable while we use the board.

Although several preferred embodiments of the present invention have been described in detail hereinabove fromFIG. 1 toFIG. 14, it should be understood that the preferred embodiments are to be regarded in an illustrative manner rather than a restrictive manner, and all variations and modifications of the basic inventive concepts herein taught still fall within the scope of the present invention. For examples, the fillingmaterial3 may be omitted; the hard board may be used with the buffering material and the filling material; there are other configurations that the fillingmaterial3 and thebuffering material2 may be arranged and these configurations should be included in the scope of the present invention.

In comparison to the prior art, the back supporting board of the present invention has the following advantages:
