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 (12, 12') to couple to the projection panel, the face panel (12, 12') having a vehicle-engaging surface to be engaged by the vehicle at the loading dock, the face panel (12, 12') including a distal edge spaced apart from the projection panel and being elongate along a primary length of the face panel (12, 12'), the face panel (12, 12') to extend from the projection panel in front of the doorway when the projection panel is mounted to the wall, the face panel (12, 12') spaced apart from the wall and movable between a standby position and a deflected position relative to the projection panel, the face panel (12, 12') positioned closer to the wall when the face panel (12, 12') is in the deflected position than when the face panel (12, 12') is in the standby position, the face panel (12, 12') to move from the standby position to the deflected position in reaction to the vehicle engaging the vehicle-engaging surface of the face panel (12, 12') upon the vehicle approaching the doorway; and a tip seal (58, 58a,b,d,e,g) to extend along the distal edge of the face panel (12, 12') including an elongate casing (60, 88) and an elongate stiffener (80, 98, 100); characterized by: the tip seal (58, 58a,b,d,e,g) including a seal flap (62, 82, 84), the elongate casing (60, 88) configured in a loop form to enable the elongate stiffener (80, 98, 100) to be disposed in the elongate casing (60, 88), the elongate stiffener (80, 98, 100) and the elongate casing (60, 88) being interposed between at least a portion of the seal flap (62, 82, 84) and the doorway when the face panel (12, 12') is in the standby position. a projection panel mountable to extend outward from the wall in proximity with the doorway; a face panel (12, 12') to couple to the projection panel, the face panel (12, 12') having a vehicle-engaging surface to be engaged by the vehicle at the loading dock, the face panel (12, 12') including a distal edge spaced apart from the projection panel and being elongate along a primary length of the face panel (12, 12'), the face panel (12, 12') to extend from the projection panel in front of the doorway when the projection panel is mounted to the wall, the face panel (12, 12') spaced apart from the wall and movable between a standby position and a deflected position relative to the projection panel, the face panel (12, 12') positioned closer to the wall when the face panel (12, 12') is in the deflected position than when the face panel (12, 12') is in the standby position, the face panel (12, 12') to move from the standby position to the deflected position in reaction to the vehicle engaging the vehicle-engaging surface of the face panel (12, 12') upon the vehicle approaching the doorway; and a tip seal (58, 58a,b,d,e,g) to extend along the distal edge of the face panel (12, 12') including an elongate casing (60, 88) and an elongate stiffener (80, 98, 100); characterized by: the tip seal (58, 58a,b,d,e,g) including a seal flap (62, 82, 84), the elongate casing (60, 88) configured in a loop form to enable the elongate stiffener (80, 98, 100) to be disposed in the elongate casing (60, 88), the elongate stiffener (80, 98, 100) and the elongate casing (60, 88) being interposed between at least a portion of the seal flap (62, 82, 84) and the doorway when the face panel (12, 12') is in the standby position.
