    Brief description of the invention.
    The object of the invention is to provide a steering device for smaller and light vehicles, such as a three-wheeled vehicle, which reduces the risk of a driver being injured in a frontal collision. To achieve good safety, the driver's seat of a vehicle must be equipped with a safety device, such as a seat belt, which reduces the driver's forward movement in the event of a frontal collision. To further improve safety, the vehicle should be designed with a front energy absorption zone that reduces the force that affects the driver of the vehicle in a frontal collision. The steering device according to the invention is designed so that the upper part of the steering device moves forward, seen in the normal direction of travel of the vehicle, away from the driver, in the event of a frontal collision. With a control device according to the invention, the risk of a belted driver coming into contact with the vehicle's control device is reduced. This is achieved in that the control device is a rigid unit and that the attachment of the control device to the supporting structure of the vehicle comprises at least one deformable part.

    Detailed Description of the Preferred Embodiment Figure 1 shows a small and light vehicle (10), in the form of a three-wheeled vehicle, with a driver's seat (11), the driver's seat (11) being equipped with a seat belt (12). The vehicle has two wheels (13) at the rear of the vehicle (10) and one wheel (14) at the front of the vehicle (10). The front wheels (14) of the vehicle (10) form part of the steering device (15) of the vehicle (10). The steering device (15) of the vehicle (10) consists, in addition to the front wheels (14) of the vehicle, of an upper part (16) with which the driver acts on the steering device (15), and an intermediate part (18), such as a axle, and a wheel mounting. (19). The upper part (6) of the guide device (15) in the embodiment shown is a guide handle, but may be a steering wheel. The steering device (15) is mounted to the vehicle (10) with a fastening device (17) located between the upper part (16) of the steering device (15) and the wheel attachment (19). The intermediate part (18) of the guide device (15) runs through the fastening device (17) and is rotatably mounted relative to the fastening device (17). The part of the fastening device (17) where the intermediate part (18) is stored can be designed as a tube (20). The control device (15) is designed as a rigid unit.
    In the embodiment shown in Figure 1, the fastening device (17) consists of the tube (20), a fastening element (21) at the lower part of the tube (20), the fastening element (21) is attached to the supporting structure (22) of the vehicle (10), and a strut arrangement (23) between the upper part of the tube (20) and a part of the supporting structure (22) of the vehicle (10). The guide device (15) with a preferred substantially vertical extension is held fastened in the supporting structure (22) of the vehicle (10) by the fastening element (21) and the strut arrangement (23). In the event of a frontal collision, the front part of the vehicle (10) is deformed and the front wheel (14) of the vehicle is pushed backwards in the normal direction of travel of the vehicle (10). When the front wheels (14) of the vehicle are pressed backwards, the strut arrangement (23) is loaded and at a predetermined load the strut arrangement (23) is deformed and the front wheels (14) of the vehicle move backwards during energy absorption. The fastening element (21) is so attached to the supporting structure (22) of the vehicle that the fastening element (21) can perform only a minor movement. As the front wheels (14) of the vehicle move backwards, seen in the normal direction of travel of the vehicle (10), the strut arrangement (23) is deformed and the minor movement of the fastening element (21) in the supporting structure of the vehicle, the upper part (16) of the steering device (15) will move forward, seen in the normal direction of travel of the vehicle (10), Figure 2 shows the position of the steering device (15) after a frontal collision. When the vehicle (10) is equipped with a seat belt (12) which reduces the driver's forward movement and when the upper part (16) of the steering device (15) moves forward, away from the driver, the risk of the driver being injured in a frontal collision is reduced. the upper part (16) of the control device (15). The distance that the upper part (16) of the steering device (15) can move forward is determined by the position of the fastening device (17) relative to the front wheels (14) of the vehicle (10) and the position of the fastening device (17) relative to the supporting structure (10) of the vehicle (10). 22). In order for the tie rod arrangement (23) to be able to keep the steering device (15) in the preferred position during normal use of the vehicle (10), when there may be forces in the longitudinal direction of the vehicle, for example when hitting a curb and forces across the longitudinal direction of the vehicle, e.g. when braking when turning, but deformed at the predetermined load, it is necessary to use two struts arranged at an angle to each other, as shown in Figure 4. By placing the struts forward, seen in the normal direction of travel of the vehicle (10), the struts to be bent, which results in a controlled movement of the upper part (16) of the steering device (15) after the front wheels (14) of the vehicle have begun to move backwards. In the embodiment shown, the strut arrangement (23) is attached directly to the supporting structure (22) of the vehicle, but in a special embodiment the strut arrangement (23) can be integrated with the fastening element (21) and the assembled unit attached to the supporting structure (22) of the vehicle, which entails a simpler mounting of the control device (15) to the load-bearing structure (22) of the vehicle. With the steering device (15) formed as a rigid unit and with the steering device (15) 4 attached to the supporting structure (22) of the vehicle (10) via a deformable part (23), the upper part (16) of the steering device (15) will move forward when the front wheels (14) of the vehicle (10) move backwards.

When the front wheels (14) of the vehicle (10) move backwards, seen in the normal direction of travel of the vehicle, the plate (27) will be subjected to a bending load in a section (30) located between the tube (20) and the rear fastening elements (29). . The section (30) will be deformed, the front wheel (14) of the vehicle (10) moving backwards, seen in the normal direction of travel of the vehicle (10), and the upper part (16) of the steering device (15) moving forwards, seen in the vehicle (10) 10) normal direction of travel. In order to have a controlled deformation of the section (30), the section (30) may be provided with some form of weakening, such as a groove or recesses. The attachment of the plate (27) to the supporting structure (22) of the vehicle (10) may be formed with one or two front fastening elements (28) and one or two rear fastening elements (29), where any part of the front fastening elements is deformed, so that the plate (27) detaches from the front fastening elements (28) at the predetermined load. Figure 8 shows the device according to Figure 7 after a frontal collision where the front wheel (14) of the vehicle (10) moves backwards, so that the upper part (16) of the steering device (15) moves forwards, seen in the normal direction of travel of the vehicle, with the steering device (15) formed as a rigid unit and with the steering device (15) attached to the supporting structure (22) of the vehicle (10) via deformable parts (28, 30), the upper part (16) of the steering device (15) will move forward when the vehicle (10) front wheels (14) move backwards.
    Figure 9 shows a variant of the embodiment according to Figure 7, where the fastening device (17) consists of a plate (31) attached to the tube (20), where the plate (31) is fastened to the supporting structure (22) of the vehicle (10) with fastening elements ( 32).
