Claim 0:
1. A rotor blade for a wind power installation, comprising:
a body extending in a longitudinal direction with a profile course from a blade connector to a blade tip,
wherein the profile course contains a profile, comprising:
a suction side and a pressure side,
a profile chord extending between a leading edge and a trailing edge of the profile and having a length defining a profile depth,
a relative profile thickness of greater than 25% of the length of the profile chord,
a mean line extending at least partially below the profile chord,
a convex region extending on the suction side from the trailing edge, and
a convex region extending on the pressure side from the trailing edge,

wherein the convex region on the pressure side defines a rounded transition region of the pressure side to the trailing edge,
wherein the mean line has, in a region in which the mean line is defined by the convex region extending on the pressure side from the trailing edge and the convex region extending on the suction side from the trailing edge, a rear local minimum situated below the profile chord, and/or
wherein the mean line has, in a region in which the mean line is defined by a convex region extending on the pressure side from the leading edge and the convex region extending on the suction side from the leading edge, a front local minimum situated below the profile chord.
