A control device for controlling an assistive device, the control device comprising: a bottom element and a cover element which can be tilted and rotated with respect to the bottom element; characterized in that the control device further comprises: a movement element made of an elastic and flexible material, connected between the cover element and the bottom element, and configured to rotate when the cover element is rotated in two opposite lateral direction, and to bend or buckle when the cover element is tilted forward and rearward; a first and a second arm (36, 38) having an elastic structure and extending to a distance from the movement element, pointing in opposite directions with respect to each other, and configured to follow said movements of the movement element; a first guide in which the first arm is fitted and which allows its movement in said lateral directions and prevents its movements so that the first arm has to bend when the movement element is tilted forward and rearward; a second guide, in which the second arm is fitted and which allows its tilting forward and rearward and prevents its movements so that the second arm has to bend when the movement element is rotated in said two opposite lateral directions; and electronic devices (18, 20, 22, 24) for detecting and indicating a change in the position or a deformation of the first and second arm (36, 38), the electronic devices (18, 20, 22, 24) being configured to generate at least one signal proportional to the tilting of the cover element forward and rearward, and at least one signal proportional to the rotation of the cover element in two opposite lateral directions. a bottom element and a cover element which can be tilted and rotated with respect to the bottom element; characterized in that the control device further comprises: a movement element made of an elastic and flexible material, connected between the cover element and the bottom element, and configured to rotate when the cover element is rotated in two opposite lateral direction, and to bend or buckle when the cover element is tilted forward and rearward; a first and a second arm (36, 38) having an elastic structure and extending to a distance from the movement element, pointing in opposite directions with respect to each other, and configured to follow said movements of the movement element; a first guide in which the first arm is fitted and which allows its movement in said lateral directions and prevents its movements so that the first arm has to bend when the movement element is tilted forward and rearward; a second guide, in which the second arm is fitted and which allows its tilting forward and rearward and prevents its movements so that the second arm has to bend when the movement element is rotated in said two opposite lateral directions; and electronic devices (18, 20, 22, 24) for detecting and indicating a change in the position or a deformation of the first and second arm (36, 38), the electronic devices (18, 20, 22, 24) being configured to generate at least one signal proportional to the tilting of the cover element forward and rearward, and at least one signal proportional to the rotation of the cover element in two opposite lateral directions. a movement element made of an elastic and flexible material, connected between the cover element and the bottom element, and configured to rotate when the cover element is rotated in two opposite lateral direction, and to bend or buckle when the cover element is tilted forward and rearward; a first and a second arm (36, 38) having an elastic structure and extending to a distance from the movement element, pointing in opposite directions with respect to each other, and configured to follow said movements of the movement element; a first guide in which the first arm is fitted and which allows its movement in said lateral directions and prevents its movements so that the first arm has to bend when the movement element is tilted forward and rearward; a second guide, in which the second arm is fitted and which allows its tilting forward and rearward and prevents its movements so that the second arm has to bend when the movement element is rotated in said two opposite lateral directions; and electronic devices (18, 20, 22, 24) for detecting and indicating a change in the position or a deformation of the first and second arm (36, 38), the electronic devices (18, 20, 22, 24) being configured to generate at least one signal proportional to the tilting of the cover element forward and rearward, and at least one signal proportional to the rotation of the cover element in two opposite lateral directions.
