Abstract
Elevator systems are described. The systems include an elevator car movable along an elevator shaft having a pit floor. A car apron assembly is provided that includes an apron frame movably mounted to the elevator car, the apron frame having a frame base, a support arm, and an apron stop at an end of the support arm opposite the frame base, and a semi-rigid curtain extending between a car sill and the frame base. A shaft stop is arranged within the elevator shaft to interact with the apron stop. The curtain transitions from a deployed state to a compressed state when the apron stop contacts the shaft stop, and when in the deployed state the curtain extends below the elevator car to block an open landing door that is lower than the elevator car when the elevator car is positioned offset and above an adjacent landing.
