Abstract
An override device is presented having a manual control, an inlet gear, and an outlet gear, which are mounted to rotate about the same axis. The inlet gear rotates the outlet gear. The manual control has a cam which, in co-operation with an intermediate part suitable for following the cam, serves to disengage the rotation of the inlet gear under torque exerted on the manual control. The manual control drives the outlet gear. The Inlet gear rotates by having a set of friction disks and spring part suitable for exerting a force to compress the disks against one another. The intermediate part carries at least one pusher-forming element, which at the end of a displacement exerts force opposing that of the spring part and relaxes the friction force on at least some of the disks.
