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.
