Abstract: Elevator systems including an elevator car having a car door sill and car apron assembly movable along an elevator shaft having a pit floor, are provided. The car apron assembly includes a collapsible guard with at least one guard element that is moveable from a deployed state to a compressed state. In the compressed state the at least one guard element is positioned within the car door sill. A guard frame is fixedly connected to the at least one guard element by one or more reinforcement elements, a translating member is arranged at each end of the guard frame, and a guide member fixedly connected to the elevator car. The collapsible guard is urged from the deployed state toward the compressed state as the guard element contacts the pit floor, and when transitioning from the deployed state to the compressed state, the translating member translates along the guide member.
