Wiping system driving mechanism for motor vehicle, has elastic unit authorizing exit of male part with respect to female part by relative translation of internal and external rings, so as to obtain disengaged clutch position of mechanism

摘要

The mechanism has an elastic unit (5) e.g. spring ring, for permitting maintenance of a male part e.g. tooth, engaging a female part (30) e.g. nick, when predetermined torque threshold is not exceeded. The elastic unit authorizes exit of the male part with respect to the female part by relative translation of internal and external rings (3, 4) parallel to a longitudinal axis when the predetermined torque threshold is exceeded, so as to obtain a declutch position of the mechanism in which the external ring is integrated in rotation to the inner ring.
