A seal assembly for sealing against a vehicle at a loading dock, wherein the loading dock includes a wall with a doorway, the seal assembly comprising: a projection panel mountable to extend outward from the wall in proximity with the doorway; a face panel to be coupled to the projection panel, the face panel comprising a front sheet, a back sheet and a distal edge, the front sheet to adjoin the back sheet, the distal edge spaced apart from the projection panel, the distal edge being elongate along a primary length of the face panel, the face panel to extend from the projection panel in front of the doorway when the projection panel is mounted to the wall, the face panel spaced apart from the wall, the face panel movable between a standby position and a deflected position relative to the projection panel, the back sheet to face the doorway when the projection panel is mounted to the wall and the face panel is in the standby position, the front sheet to face away from the doorway when the projection panel is mounted to the wall and the face panel is in the standby position, the face panel to be positioned closer to the wall when the face panel is in the deflected position than when the face panel is in the standby position; and a first seam and a second seam to be positioned where the front sheet adjoins the back sheet, the front sheet to bulge away from the back sheet between the first seam and the second seam to create a blister defining an elongate chamber to contain a variable volume of air between the front sheet and the back sheet, the face panel to move from the standby position to the deflected position in reaction to the vehicle engaging the front sheet upon the vehicle approaching the doorway. a projection panel mountable to extend outward from the wall in proximity with the doorway; a face panel to be coupled to the projection panel, the face panel comprising a front sheet, a back sheet and a distal edge, the front sheet to adjoin the back sheet, the distal edge spaced apart from the projection panel, the distal edge being elongate along a primary length of the face panel, the face panel to extend from the projection panel in front of the doorway when the projection panel is mounted to the wall, the face panel spaced apart from the wall, the face panel movable between a standby position and a deflected position relative to the projection panel, the back sheet to face the doorway when the projection panel is mounted to the wall and the face panel is in the standby position, the front sheet to face away from the doorway when the projection panel is mounted to the wall and the face panel is in the standby position, the face panel to be positioned closer to the wall when the face panel is in the deflected position than when the face panel is in the standby position; and a first seam and a second seam to be positioned where the front sheet adjoins the back sheet, the front sheet to bulge away from the back sheet between the first seam and the second seam to create a blister defining an elongate chamber to contain a variable volume of air between the front sheet and the back sheet, the face panel to move from the standby position to the deflected position in reaction to the vehicle engaging the front sheet upon the vehicle approaching the doorway.
