Protection system for elevators

A system for protecting a movable element of an elevator, wherein the movable element comprises a top side, a bottom side, a lateral side, a top edge between the lateral side and the top side and a bottom edge between the lateral side and the bottom side, the system comprising:

• a protective structure;
• a shock-absorbing system, and
• a collision detector,
• wherein the protective structure is connected to the movable element via the shock-absorbing system holding the protective structure in an operating position and allowing the protective structure to move against the driving direction of the movable element, when the protective structure hits an object during driving of the elevator,
• wherein the protective structure has a top protective element which in the operating position is arranged above the top edge and is extending along the top edge,
• wherein the protective structure has a bottom protective element which in the operating position is arranged below the bottom edge and is extending along the bottom edge,
• wherein the collision detector is to detect when the top protective element or the bottom protective element structure is moved out of the operating position of the protective structure to detect a collision,
• wherein the protective structure is designed such that the top protective element extends along the top edge and the protective structure comprises a recess from the top protective element towards the central region of the top side to access the top side,
• wherein the movable element comprises an electronic detector configured to detect a penetration of an object through the surface spanned between the top edge and the bottom edge.
