1. Field of the Invention
The present invention relates to an airbag structure, and more particularly to an airbag structure applied to a mattress for convenient use.
2. Description of Related Art
A bed patient is likely to suffer from skin diseases resulted from lying on the bed for a long time without movement therefore an air mattress is created to help blood circulation. A conventional air mattress has several interconnected airbags arranged upon the mattress and an air pump for inflating the air cells.
Based on the above-mentioned details, although the techniques according to the prior arts are successfully used to prevent skin diseases, the shape of the air structure of the mattress still results in patient discomfort. Accordingly, there is a long and unfulfilled need to overcome the foregoing problem.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide an airbag for achieving a minimal crevice space between adjacent airbags, therefore avoiding patients easily sinking into the crevices and thus further avoiding discomfort from irregular positioning on the bed.
The present invention relates to an airbag structure comprising an airbag with multiple straight walls defining a hermetic interior; a plurality of baffles received in the interior of the airbag and a plurality of valves for communicating the interior with an air supply. Thus, contact area between the airbags and the human body is broad. Hence, the shape of the airbag structure of the mattress results in particularly good comfort for the patient.
However, other aspects and further features, advantages and benefits of the invention will become apparent in the following description taken in conjunction with the following drawings. The accompanying drawings are incorporated in and constitute a part of this application and, together with the description, serve to explain the principles of the invention in general terms.
BRIEF DESCRIPTION OF THE DRAWINGS
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of the illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments maybe utilized and structure changes maybe made without departing from the scope of the present invention.
With reference to
It is to be appreciated that the belt structure attachment points within the airbag may be varied without departing from the structure as herein claimed. It is further to be appreciated that the belt structure may be formed as a single cruciform extrusion.
According to the present invention, an airbag structure is provided. After the airbags are arranged in a row, not only are the airbags located upon the pad body stably, but also the patient is able to directly or indirectly lie down flat upon the airbag structure. The inconvenience of the prior art wherein irregular support caused the patient to sink into the crevices between the airbags is eliminated by the present invention.
It is understood that the above description is intended to be illustrative, and not restrictive. Many other embodiments will be apparent to those of the skill in the art upon reviewing the above description. The scope of the invention should, therefore, be determined with reference the appended claims, along with the full scope of equivalents to which such claims are entitled.
Claims
1. An airbag structure comprises:
- an airbag with multiple straight walls defining a hermetic interior;
- a plurality of baffles received in the interior of the airbag; and
- a plurality of valves for communicating the interior with an air supply.
2. The airbag structure as recited in claim 1, wherein the airbag is configured as a rectangular prism with four contiguous long side walls and two opposed end walls connected to respective ends of the long side walls.
3. The airbag structure as recited in claim 1, wherein the plurality of baffles are configured as a single jointed cruciform, extends along the interior of the airbag, and distal edges of the plurality of baffles are securely connected to an interior periphery of a respective one of the long side walls.
4. The airbag structure as recited in claim 3, wherein the plurality of baffles comprise four belts each joined to the others at a first long edge thereof.
