The invention relates to a rotor blade for a wind power installation and a wind power installation comprising at least one rotor blade. If the wind attack surface, i.e. the rotor blade surface, is small, the level of strain exerted upon said installation is correspondingly reduced and the rotor blade is easier to transport. However, minimum dimensions are required for the rotor blade in keeping with the size of the installation and must clearly be respected. In order to create a rotor blade which has the required aerodynamic surface and is embodied in such a way that the surface of the rotor blade and the depth thereof can be reduced in given circumstances, part of the surface of said rotor blade is deformable or moveable.
