Abstract
A device for generating a return force for a control stick that is movable from a neutral position along a travel path, includes a mechanical connection member connecting the stick to a resilient return member for returning the stick towards the neutral position. The mechanical connection member and the resilient return member produce, over a first portion of the travel path, a first strength of return force and, over a second portion of the travel path, a second strength of return force. A transmission part is mechanically connected to the stick so that any stick movement along the second portion corresponds to turning movement of the transmission part, and so that the return force to the stick is transmitted to the stick positioned in the second portion.
