Abstract
An awning, in particular an awning with a supporting arm, the cloth (1) of which can be unwound from a tube or winding shaft (2) driven by an electric motor (9) and in which are provided means for measuring the drive torque which supply a variable representing the windforce acting on the awning cloth. The measuring means are associated with a logical processing unit (15) in which are recorded three torque values, namely a danger, a safety and an all-clear value, on the basis of which values the LPU allows or activates the partial or complete unwinding or winding of the cloth.
