Abstract
Head curtains for dock shelters or dock seals are disclosed. An example dock apparatus disclosed herein includes a first weather barrier and a second weather barrier. The first and second weather barriers are positioned laterally of a doorway of a loading dock and compressible by a vehicle. The lateral weather barriers include inner surfaces that are to bulge toward each other in response to the vehicle compressing the lateral weather barriers. A head curtain is at least partially positioned between the lateral weather barriers and being engagable by the vehicle, the head curtain having a lateral stiffness such that in response to the vehicle engaging the head curtain and compressing the lateral weather barriers, the head curtain becomes pinched between the bulging inner surfaces to restrict a vertical movement of the curtain.
