An elevator system comprising: an elevator car movable along an elevator shaft , the shaft having a pit floor , the elevator car having an elevator car door sill ; and a car apron assembly comprising: an apron frame movably mounted to the elevator car, the apron frame having a frame base , and a support arm ; and a semi-rigid curtain attached to the elevator car door sill and extending to the frame base ; wherein: when in the deployed state the semi-rigid 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; characterized in that the apron frame comprises an apron stop at an end of the support arm opposite the frame base ; the car apron assembly further comprises a shaft stop arranged within the elevator shaft at a stop height from the pit floor , the shaft stop positioned within the elevator shaft to interact with the apron stop ; the semi-rigid curtain transitions from a deployed state to a compressed state when the apron stop contacts the shaft stop and as the elevator car moves toward the pit floor . an elevator car movable along an elevator shaft , the shaft having a pit floor , the elevator car having an elevator car door sill ; and a car apron assembly comprising: an apron frame movably mounted to the elevator car, the apron frame having a frame base , and a support arm ; and a semi-rigid curtain attached to the elevator car door sill and extending to the frame base ; wherein: when in the deployed state the semi-rigid 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; characterized in that the apron frame comprises an apron stop at an end of the support arm opposite the frame base ; the car apron assembly further comprises a shaft stop arranged within the elevator shaft at a stop height from the pit floor , the shaft stop positioned within the elevator shaft to interact with the apron stop ; the semi-rigid curtain transitions from a deployed state to a compressed state when the apron stop contacts the shaft stop and as the elevator car moves toward the pit floor . an apron frame movably mounted to the elevator car, the apron frame having a frame base , and a support arm ; and a semi-rigid curtain attached to the elevator car door sill and extending to the frame base ; wherein: when in the deployed state the semi-rigid 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; characterized in that the apron frame comprises an apron stop at an end of the support arm opposite the frame base ; the car apron assembly further comprises a shaft stop arranged within the elevator shaft at a stop height from the pit floor , the shaft stop positioned within the elevator shaft to interact with the apron stop ; the semi-rigid curtain transitions from a deployed state to a compressed state when the apron stop contacts the shaft stop and as the elevator car moves toward the pit floor . when in the deployed state the semi-rigid 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; characterized in that the apron frame comprises an apron stop at an end of the support arm opposite the frame base ; the car apron assembly further comprises a shaft stop arranged within the elevator shaft at a stop height from the pit floor , the shaft stop positioned within the elevator shaft to interact with the apron stop ; the semi-rigid curtain transitions from a deployed state to a compressed state when the apron stop contacts the shaft stop and as the elevator car moves toward the pit floor . <EOS>
