There is provided a bedrest including an inflatable bladder, which is in general a triangular shaped structure when inflated and a microprocessor based hand controller for inflating and deflating the bladder. The bladder contains an interior baffle which extend for primarily the length of the bladder fixed to interior walls of the bladder to form an inverse triangle inverse to the triangle formation of the bladder when inflated. The interior baffle therefore enables the structure to form more precisely into the desired triangular shape in order to perform a more effective position when inserted under the mattress in the head location of the bed. The microprocessor based hand controller enables an individual to inflate or deflate the bladder to any desired amount with a simple control. In addition, the hand controlled microprocessor permits computer programming so that the mattress can be automatically raised and lowered to different levels during different periods of time. An additional feature is that one does not need to simply continue to hold the switch down in order to raise or lower the bladder portion but instead can press a simple button after the entire hand controlled microprocessor has been preprogrammed so that any one of a number of different adjustments can be made and these can be made at any given time and preset to any given time and interval.

1. Field of the Invention
The present invention generally relates to an adjustable bedrest positioned under a mattress. More particularly, the invention relates to an inflatable triangular-shaped bladder for use in raising the head or feet of a user and to a microprocessor for controlling the amount of air in the bladder.
2. Description of Related Art
Having thus described the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
FIG. 1 illustrates an adjustable bed according to the present invention showing a bladder of the invention at the head of the bed in an elevated position;
FIG. 2 is a view of the triangular shaped bladder of the present invention;
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.
Referring more particularly to the drawings, FIG. 1 shows a bed 10 for use with the present invention. The bed 10 is generally rectangular and has conventional box springs or other suitable foundation 12, and a mattress 14. In other words, the bed used with the present invention may be a conventional bed. The mattress 14 has a head/back portion 15 and a leg/foot portion 13.
An inflatable bladder 16 having an air supply tube 18 for inflating and deflating the bladder is provided for raising and lowering the head portion 15 of the mattress. As shown in FIG. 1 there is also provided an inflatable bladder 17 placed under the knees of the user. It should be understood that bladder may be placed under the foot portion of the mattress. The air supply tube 18 is connected to a motor 19 that is controlled by hand held microprocessor 20.
