Zusammenfassung:	The guide assembly comprises corner brackets for mounting to the upper corners of a door jamb. Each corner bracket supports an elongated curvilinear track section and an elongated cam track. The curvilinear track section and the cam track each have a central concave portion. The guide assembly further comprises a support bracket which is pivotally mounted to an upper corner of the top panel of the sectional door. The pivoting support bracket has a cam follower which engages and follows the cam track, so that pivoting of the support bracket is responsive to the shaping of the cam track. The assembly is designed to steer the upper edge of the top panel away from the cable drum of a lifting assembly when passing thereby, all with the objective of reducing headroom.
