In order to provide a durable loading dock shelter with an effective seal, the dock shelter is provided with a face panel that is relatively lightweight and firm, yet moveable for sealing against vehicles of various size and position. The face panel can be used as a side curtain or a head curtain. To provide the face panel with durability while minimizing its weight, the face panel is thermoformed of twin sheets of plastic to provide a durable outer shell with a hollow interior. In some embodiments, the face panel is moveable by virtue of an integral living hinge that connects the face panel to a generally stationary support panel. |

DETAILED DESCRIPTION A dock shelter is provided with a face panel that is relatively lightweight and firm, yet moveable for sealing against vehicles of various size and position.
The face panel can be used as a side curtain or a head curtain.
To provide the face panel with durability while minimizing its weight, the face panel includes a rather stiff and durable outer shell with a hollow interior.
In some embodiments, the face panel is moveable by virtue of an integral living hinge that connects the face panel to a generally stationary support panel.
In some embodiments, the outer shell of the face panel comprises two half-shells that are fused to each other.
In some embodiments, the two half-shells provide both the face panel and the support panel.
In some embodiments, both the face panel and the support panel are hollow.
In some embodiments, the living hinge between the face panel and support panel is corrugated for greater flexibility.
In some embodiments, a torsion spring urges the face panel to an extended position.
In some embodiments, a pliable elongated member limits the pivotal extension of the face panel.
In some embodiments, the face panel includes a flexible extension plate that helps protect the main body of the face panel from wear.
In some embodiments, the hollow face panel includes recessed areas that enhance the face panel's rigidity.
