摘要： A safety device for the closure edge (5) of the leaf (2) of a door or the likecomprising a door closing profile in the form of a hollow rubber profile (6) elasticallydeformable, the cavity (7 ) is connected, on one end face, through a rigid or flexible pipe(11) to a signal receiver-converter (12) air pressure waves, and of which the other end faceis connected via a further rigid or flexible pipe (13) to an air pressure wave transmitter(14), a pressure oscillation wave generated by the transmitter being with respect to itspulse width, smaller chosen and / or its pulse frequency being selected to be greater orsmaller than that of a distress pulse triggered by the impact of the hollow rubber in abarrier, which ensures at least for the duration of operation and driving the leaf por youself-monitoring of operational safety.
