Patent Images
1. A thrust return mechanism intended for a thrust return pedal, comprising:
- an electric motor;
a transmission connected to the motor; and
a control member connected to the transmission;
wherein the transmission comprises;
a first driving pulley;
a first set of coaxially rotatable half pulleys;
a first cable having first and second ends connected to respective said coaxially rotatable half pulleys in the first set of coaxially rotatable half pulleys, a center portion of the first cable being wound around the first driving pulley;
wherein the first set of coaxially rotatable half pulleys are interconnected with one another by a first elastic element, the first elastic element urging the first set of coaxially rotatable half pulleys in opposite rotational directions to one another so as to tension the first cable.
