Abstract: A member for supporting a vehicle or watercraft steering wheel, the member including a fixed support device, firmly connected in rotation, to said vehicle, or watercraft, and a device supporting the steering wheel that is rotatable with the steering wheel and connected to a device for transmission of rotation of the steering wheel towards, or to, a device for directing said vehicle, or watercraft, and a device that carries an aid device to the pilot of the vehicle, or watercraft. The carrying device is in a fixed, or firm, condition, in rotation with respect to the steering wheel, so as to allow an easy operation or displaying of the aid device for any position taken by the steering wheel.

Abstract: Disclosed is an apparatus for varying the direction of travel of a vehicle, including a rotatable unit operable by the vehicle driver, in particular by gripping, to vary the vehicle's direction of travel, and a support, or hub for rotatably supporting the rotatable unit, having a respective longitudinal axis and connected fixedly to the vehicle. The support for rotatably supporting the rotatable unit has a unit for transferring movement of the rotatable unit to a corresponding unit for controlling the vehicle's direction of travel, such the rudder of the water-borne vehicle, through a corresponding transmission. The transfer unit transfers movement of the rotatable unit, or steering wheel to the unit for controlling the vehicle's direction of travel, in particular through the transmission to the self-same controlling unit, preferably through the rotary transmission shaft, with a transmission ratio of 1:1.

Abstract: A member (10) for controlling the direction of a vehicle, preferably in the form of a steering wheel for controlling the direction of a nautical vehicle, or boat, and includes a rotatable body (11), which can be manually operated by the skipper of the vehicle for controlling the direction of the vehicle and which is operatively connectable to unit defining, or determining, the direction of travel of the vehicle. The member includes a unit, or hub, (12) supporting the rotatable body, which include a component (14) fixed to the structure of the vehicle which rotatably support respective units (16) for supporting, or coupling, the rotatable body which can be operated manually, the unit fixed to the structure of the vehicle supporting corresponding unit (18) which can be used, in particular which can be operated and/or viewed, by the skipper, which remain fixed during the rotation of the rotatable body.
