Adjustable Back Rest Structure
An adjustable back rest structure is essentially composed of a soft mat and a plurality of leaning pads. The soft mat at least has a fastening surface, and each of the leaning pads is provided with a locator at the back surface thereof. The soft mat can be covered or laid on a seat, a chair or a bed or the like which is either for sitting or lying. The fastening surface of the soft mat is exposed to be fastened with the locators of the leaning pads thereby fastening the locators respectively at a proper position which matches nearly for individual user's backbone curve thereby enabling the user to sit down or lie down in an easy posture.
This application is a divisional application of U.S. patent application Ser. No. 12/464,362 filed May 12, 2009, the contents of which are hereby incorporated by reference in their entirety.
BACKGROUND OF THE INVENTION1. Field of the invention
The present invention relates to adjustable back rest structure, and more particularly, to adjustable back rest structure for a bed or seats such as car seat and chair, that contains a plurality of adjustable pads to be affixed to a soft mat so as to sustain the user's body on the back rest comfortably matching the user's back bone curve.
2. Description of the Prior Art
Referring to
Although there are many kinds of back rests for a chair manufactured according to the figure of the human backbone curve or with extra adjustable means, claiming able to solve the above shortcomings, actually there are following common flows:
1. The back rest configured as a human backbone curve has by no means a universal sustention effect as everybody has his/her own particular stature and the sitting posture.
2. The back rest equipped with an adjustable structure is deemed to be accompanied with heavy sophisticated means for assembling that leads to an increased fabrication cost and an expensive market price not affordable for everyone.
For these shortcomings noticeable on the prior art, an improvement is seriously required.
In view of the foregoing situation, the inventor of the present invention herein conducted a scrupulous research based on many years of experience gained through professional engagement in this field, with continuous experimentation and improvement culminating in the development of the adjustable back rest structure of the present invention.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide an adjustable back rest structure in which a soft mat is used to be laid on a seat, chair, bed or the equivalent for leaning against or lying down comfortably matching for the user's backbone curve.
It is another object of the present invention to provide an adjustable back rest structure which contains a portable soft mat with a plurality of leaning pads to sustain the user's body on a seat, chair or bed matching for his/her backbone curve anywhere.
It is one more object of the present invention to provide an adjustable back rest structure whose soft mat is covered on an extra sustentation member that can serve a better sustention effect accompanying the leaning pads.
To achieve these and other objects mentioned above, the adjustable back rest structure of the present invention is essentially composed of a soft mat and a plurality of leaning pads. The aforesaid soft mat, which is formed of cloth, or a cloth material laminated with soft rubber foam or soft plastic foam that makes the soft mat able to be portably rolled up or folded for putting away. A locator, which is provided on the rear of the leaning pad, is to be easily fastened with the fastening surface of the soft mat so as to fasten the leaning pad firmly on the soft mat. When in use, the soft mat is covered on, or laid on a seat, chair, bed or the like. The fastening surface is left exposed for the user to set the leaning pads appropriately on proper positions of the soft mat in accordance with his/her backbone curve so as to form a comfortable posture for leaning against or lying down. In the meantime, for a deep chair, a supplementary sustentation member can be inserted under the soft mat to aid the leaning pads to help the user's pose to match the backbone curve to the best.
These features and advantages of the present invention will be fully understood and appreciated from the following detailed description of the accompanying Drawings.
Referring to
The soft mat 1 having at least a fastening surface 11 is made of cloth able to be rolled up or folded for putting away.
The leaning pads 2, each provided with a locator 21 on the rear surface, has a buffering effect. The number of the leaning pads is not limited, but preferably 2 to 5.
The locators 21 are to be fastened to the fastening surface 11 of the soft mat 1 each adjustably set at a proper position.
The fastening surface 11 of the soft mat 1 is like a looped or hooked surface of fasteners, Velcro or the like to be fastened with the corresponding locator 21's fasteners like a hooked or looped surface thereby firmly grabbing the leaning pad 2 at any desire position on the soft mat 1.
The size and shape of the leaning pads 2 may be made identical or different with one another for the user to select optionally.
Referring to
Meanwhile, the fastening surface 31 of the fastening strap 3 is like a hooked or looped surface of fasteners, and the locator 21 of the leaning pad 2 also has a corresponding looped or hooked fastening surface so as to fasten the leaning pad 2 firmly with the soft mat 1.

Therefore, by removing the stacked leaning pads at random, the user may properly fill the clearance between the backbone and the chair or the bed so as to assure a reliable sustention effect.
In short, it emerges from the description of the above embodiments that the invention has several noteworthy advantages, in particular:
1. The product of the present invention is applicable to any furniture for sitting and lying to sustain the user with a right and comfortable posture by only adjusting the leaning pads to a proper position.
2. The equipment is portable to any place for use.
3. A supplementary sustentation member can be inserted under the soft mat to aid the leaning pads to correct the user's pose to match the backbone curve as near as possible.
4. The equipment is widely applicable to various kinds of seats, chairs, beds sofas, vehicle seats or Japanese Mat (Tatami).
Many changes and modifications in the above described embodiments of the invention can, of course, be carried out without departing from the scope thereof.
Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the cope of the appended claims.
