Abstract
Gear motor assembly (2) comprising a motor (4) and a gear (6), the gear (6) comprising an input end (12), an output end (14), a kinematic chain with a drive element (18) and an actuation element (20) for actuating the drive element (18), a support element (16a, 16b) to which the actuation element (20) is coupled, and a safety element (22), the drive element (18) forming part of the safety element and the safety element being removable from the kinematic chain, the safety element (22) being able to pass from an inserted state, in which it is incorporated into the kinematic chain, to a removed state, in which the kinematic chain is interrupted. When the safety element (22) is inserted, its drive element (18) engages with the actuation element (20) coupled to the support element (16a, 16b), and when the safety element (22) is removed, its drive element (18) is separated from the actuation element (20) coupled to the support element.
