Abstract

Door elements are disclosed herein. An example door element includes a first flexible door movably coupled relative to a wall between at least a first closed position to cover a first portion of a doorway, a first open position to enable a vehicle to access to the doorway, and an intermediate position to engage a first surface of the vehicle when the vehicle is adjacent the doorway. The door element also includes a second flexible door movably coupled relative to the wall between at least a second closed position to cover a second portion of the doorway, a second open position to enable the vehicle to access the second portion of the doorway, and a second intermediate position to engage a second surface of the vehicle when the vehicle is positioned adjacent the door opening, where the first and second flexible doors each deform to pivot relative to the wall.
