The safety device (1) is operated between an opening position and a closing position by guide rails, where the door leaf is equipped with pull ropes (5), which are fixed in the lower region of the door leaf and are guided by deflections (11). A fixed base (9) is provided with an upper part with movably placed connecting element and changeable in its position towards base on a rotational axis (8). A length change of the pull rope is determined by the upper part during an operation of the door leaf. |
