Beschreibung
Zusammenfassung:	A dock seal assembly for an opening in a wall, said seal assembly having a resiliently flexible head seal supported by upright, parallel track means mounted upon the wall adjacent the sides of said opening near the upper end thereof. Spring-biased annular means is supported upon the wall for rotation about a horizontal axis near the upper end of said opening and is connected to the head seal by sheet means which covers said upper end of the opening when the head seal is lowered. The sheet means also serves to raise the head seal when it is released from an anchored, lowered position.
