Abstract
Example weather barrier apparatuses disclosed herein include vehicle-actuated mechanisms for forcibly pressing a seal member down against a roof of a vehicle parked at a loading dock. In some examples, rather than relying on gravity alone, rearward movement of the vehicle mechanically expands a seal member to create sufficient reach and sealing pressure to press the expandable seal member firmly against vehicle roofs of various heights and positions. In some examples, an example vehicle-actuated mechanism disclosed herein forces a compressible seal down against the vehicle's roof and maintains a compressive sealing force over a range of roof heights and positions. Some example weather barrier apparatuses disclosed herein include example means for mitigating certain jam conditions.
