Abstract: A loading dock shelter with head pad assembly and hinge gap closure wherein reinforced side wing assemblies seal corner/hinge areas, as a truck/trailer backs into the loading dock, to thereby form a protective weather seal for the dock. Respective side wings for right and left portions of the shelter are cantilevered to set the wings outwardly of the door of the dock, when the dock is in use, thereby filling the gap between door jamb and truck/trailer open doors. Each attached side wing is thus extended outwardly to seal the gap between trailer and dock shelter. The semi-flexible nature of the wings permits each one to set itself against the inside of vehicular open doors, notwithstanding possible off-center positioning of the vehicle. This head pad assembly is so conformed that its effective life is extended over the norm.
