This clutch comprises centrifugal weights (11) which are arranged radially in a hub (12) fastened to the output shaft (2) of an electric motor (1) returned to, the position of rest by means of springs (21) and which when the centrifugal force is sufficient can come into, engagement with the axial ends (26a) of an elastic ring (26) capable of transmitting the torque of the shaft (2) frictionally to a part (28) carrying an input pinion toothing (4) of a gear train for controlling the part to be driven. This arrangement simplifies the structure of the clutch in comparison with that of known clutches.

Why it's free to use
- Filed January 22, 1990 and granted November 15, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 22, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 22, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
