Abstract:
In order to disclose attaching means (3) for attaching a blade section (2) of a fan blade (1), in particular of a smoke extractor fan, to a fan hub, as well as a fan blade (1), which guarantee a high tensile strength even at high temperatures, wherein the attaching means (3) and fan blades (1) are to be produced so as to save as much weight as possible, it is proposed that the attaching means (3) have a connecting section (5) embodied to produce a high-tensile connection to a blade section (2) of a fan blade (1), which connecting section can be arranged essentially in the interior of the blade section (2).
