Beschreibung
Zusammenfassung:	An aircraft seat includes an actuator and a movement transmission device. The transmission device includes a frame provided with an immobilizing portion and a drive shaft. The transmission device further includes a gear wheel provided with coupling teeth having inclined side walls and a sleeve with an immobilizing portion complementary to the immobilizing portion of the frame, and coupling teeth having inclined side walls. The transmission device also has an elastic member configured to push the sleeve. The stiffness of the elastic member and the inclination of the side walls of the coupling teeth of the gear wheel and sleeve are chosen such that, when a torque greater than a threshold torque is applied to the gear wheel, the sleeve slides on the drive shaft from a position of coupling the sleeve to the gear wheel to a position of immobilizing the sleeve relative to the frame.
