Weather barrier apparatuses for sealing or sheltering vehicles at loading docks

This invention describes a system for sealing the gap around a truck at a loading dock to protect against weather. It uses a vertical support attached to the building wall, from which a flexible side seal extends. This side seal is designed to compress when a vehicle is present, and it supports a rear edge seal that directly touches the back of the truck. The rear edge seal itself has a special internal design with a core that includes a gap, specifically between an upper and lower section, to improve its sealing performance.
