Then the one to be secured Person ascend or descend unhindered.
  • the invention is based on the recognition that in certain exceptional situations, especially in unconscious persons and the as a rule resulting body positions or postures these persons an increased tensile load on the safety gear or on the locking bar is exercised.
  • the difference to the first or normal Tensile load is referred to here as the second additional tensile load.
  • this second additional tensile load in particular occurs in the described exceptional situations, a safety catch swung out, with which the housing can be locked in the guide rail. Consequently, the housing in the guide rail is no longer movable and the The safety gear can not go down unhindered. In other words is a crashing, for example, unconscious person by this invention Design of the safety catch automatically collected, because the locking latch the housing in the guide rail effectively locked.
