Fühler-Vorrichtung für ein Bett und Bett mit Fühler-Vorrichtung

摘要

A sensing unit (2) to be positioned between the matress (22) of a bed and the bed frame (20) for monitoring an occupant of the bed, consists of closely spaced upper and lower steel plates (4,6) between which is located a point sensor (16), such as a Hall effect transducer or a reed switch. The upper plate (4) flexes in response to the weight of an occupant. The sensing unit (2) is to be attached to a control unit (26,30) which generates an audible and visible alarm signal when the occupant leaves the bed. In a different embodiment, sensors are located in the bed frame to monitor the occupant of the bed.
