Awning

Abstract

An awning comprising a fabric roller, a fabric, and a drop arm. The fabric is connected to the fabric roller in the region of an inner fabric edge and to the drop arm in the region of an opposite outer fabric edge. The drop arm can be adjusted via a drive device between a fully retracted minimum position P 0 , in which the fabric is wound as tightly as possible on the fabric roller, and a fully extended maximum position, in which the fabric has the widest possible span. The drop arm is moved between the minimum position and the maximum position along a curved path of movement, wherein a distance to a reference plane in the maximum position is at least 8.0 times as great as a distance from the reference plane in a position extended by 50% along the reference path.
