The system has one or two arms (2) may on both sides of the bed and which may pivot in a horizontal or a vertical plane. Each arm may slide in a cylindrical housing (6) of diameter slightly larger than the arm, mounted on a fixing post (4), associated with a casing (5). The casing may be mounted at the head of the bed to pivot with the arm in a vertical plane. The casing houses part of the electrical circuit. The electrical system actuates an alarm when the arm is pivoted. The alarm may vary according to whether the arm pivots vertically or horizontally. It may be a sound or a luminous alarm in the region of the bed. The arm may be telescopic. |
