Abstract: 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.

Abstract: The invention relates to a safety device for furniture with at least one movable element which can be moved by a motor-driven positioning drive controlled by operating controls, particularly the head and/or foot of a base for a bed, or a seat and/or backrest element of an armchair, where the positioning of the element forms a gap in which an object or body part can become trapped as a result of the movement of the element. If a body part becomes trapped, this can lead to serious injury. Objects must also be prevented from becoming trapped, as they can cause damage to the furniture. According to the invention, at least one contact element is positioned in the gap which, when subjected to the pressure applied by an object or body part becoming trapped, closes an electric circuit which bridges a switch associated with one of the operating controls, the closing of which prevents further movement of the positioning drive.
