Abstract: The invention relates to a holding device for in each case one belt of a safety binding for fitting to a lateral profile rod of a bed frame. A substantially U-shaped holding block, which can be fitted from below on to the profile rod and which is fixable thereto carries a belt ring essentially shaped like a rectangular frame and connected in articulated manner therewith. This can carry a hollow cylindrical sleeve serving as a rotary roll or cylinder for the belt. One leg wall of the U-shaped holding block carries tapped holes for clamping screws for fixing to in each case one lateral profile rod of the bed. The other leg wall is provided with an inwardly open, trough-shaped recess for the pivotable mounting of the belt ring and can be covered by the profile rod of the bed.

Abstract: The invention relates to a pendulum means with a symmetrical post carrying two fixed magnets, each of which faces a movable magnet. The two movable magnets are coupled together by a rocker, so that alternately one assumes the minimum distance and the other the maximum distance with respect to the facing fixed magnet. A diaphragm movable at right angles to the magnetic field is associated with the pair of magnets, so that it alternately blocks one field and frees the other.The rocker and linkage systems carrying the magnets and the locking device are coupled together by a weight, e.g. a ball movable downwards along the sloping surface of a rocker.
