Patent ID: 8337077

Claim:
Unidirectional coupling-clutch runner comprising a coaxial pinion ( 1 ) and wheel ( 6 ) which pivot relative to one another, characterized by the fact that it comprises a first driving part ( 14 ) that is angularly integral with the pinion ( 1 ) comprising at least one elastic catch ( 15 ) with the general shape, in plan view, of a C, one branch of which is elongated and terminates with a free end; that it also comprises a second driving part ( 17 ) that is angularly integral with the wheel ( 6 ) and that is coplanar with the first driving part ( 14 ) comprising an internal wolf-toothing ( 16 ); and by the fact that in the neutral rest position the first and second driving parts ( 14 , 17 ) do not touch one another, the end of the elastic catches ( 15 ) in the rest position which are not elastically deformed being located on a circumference (a) whose diameter is larger than a circumference which goes through the top of the wolf-teeth ( 16 ) and smaller than a circumference going through the bottom of the teeth ( 16 ) of the second driving part.
