(4) FIG. 3 shows an exemplary embodiment of a new and improved steering wheel.

DETAILED DESCRIPTION

(5) In FIG. 1 an exemplary embodiment of the new and improved motor vehicle 10 is represented schematically in longitudinal section. FIG. 2 in a schematic cross-sectional representation shows an example of a position of the fitted steering wheel 11 in a straight-ahead position. The motor vehicle comprises a windshield 29. The motor vehicle 10 furthermore comprises the steering wheel 11, which is, in particular, fitted to a steering column 26. The steering column 26 is, in particular, designed in such a way that the steering wheel 11 is height-adjustable and/or adjustable in a longitudinal direction.

(6) The steering wheel 11 is arranged, as is usual, in the vehicle interior 31 of the motor vehicle 10 and hence behind the windshield 29, in particular behind a dashboard support 28. A front side 17 of the steering wheel 11 is arranged facing rearwards into the vehicle interior 31 and a rear side 18 of the steering wheel 11 is arranged facing forwards towards the dashboard support 28.

(7) The motor vehicle 10 furthermore comprises a ventilation system 27. The ventilation system 27 is designed to generate an air flow 24, particularly in such a way that the air flow has a higher temperature than a temperature of the vehicle interior 31. For this purpose, the ventilation system 27 preferably comprises a heating device. The ventilation system 27 may furthermore comprise a dehumidifier. The ventilation system 27 is, in particular therefore, a climate control system.

(8) The ventilation system 27 has a fluid-ducting connection to the steering wheel 11, in particular by means of a feed duct 25. This feed duct 25 may be arranged, at least in portions, next to the steering column 26, for example, in particular parallel to the steering column 26. The air flow 24 generated by the ventilation system 27 can be ducted through the feed duct 25 to the steering wheel 11, in particular to the rear side 18 of the steering wheel 11.

(9) The steering wheel 11 is represented schematically in a detailed view in FIG. 3. The steering wheel 11 comprises a steering-wheel rim 12, a steering-wheel center 13 and at least one steering-wheel spoke 14. The steering-wheel center 13, as is usual, is arranged centrally in the steering wheel 11. The steering-wheel rim 12 is situated at a distance from the steering-wheel center 13, running around the steering-wheel center 13, in particular in a closed annular shape. The steering-wheel rim 12 comprises a rim outer face 15. This is the circumferential face of the steering-wheel rim 12 and the face which the driver touches with at least one hand when steering. At least the one steering-wheel spoke 14 extends substantially radially from the steering-wheel center 13 to the steering-wheel rim 12. At least the one steering-wheel spoke 14 may also be of a multiple-arm design. In particular, the steering wheel 11 comprises multiple steering-wheel spokes 14, in particular three, wherein one of the three steering-wheel spokes 14 is connected to the steering-wheel rim 12 in a lower area 20 of the steering-wheel rim 12, in particular in a six o'clock position. The other two of the three steering-wheel spokes 14 in this example each extend to one side of the steering-wheel rim 12.

(10) The steering wheel 11 comprises an air duct 21, which is designed to duct an air flow 24. In the illustrated embodiment, the air duct 21 is provided with at least one air outlet 23, which is designed in such a way that the air flow 24 emerging from the air outlet 23 meets the windshield 29 when the steering wheel 11 is fitted at its intended location in the motor vehicle 10, particularly when the steering wheel 11 is situated substantially in the straight-ahead position.

(11) At least the one air outlet 23 is preferably arranged in the steering-wheel rim 12, preferably in an upper area 19, in particular in a twelve o'clock position. It is depicted in this way in the figures.

(12) It is also possible for at least the one air outlet 23 to be arranged in the steering-wheel spoke 14, or in one of the steering-wheel spokes 14, or in the steering-wheel center 13. Furthermore, it is feasible for the air duct 21 to comprise multiple air outlets 23, which are arranged in the various parts of the steering wheel 11, that is to say in the steering-wheel rim 12 and/or in the steering-wheel center 13 and/or in the steering-wheel spoke 14.

(13) The air outlet 23 may be formed from multiple apertures. The air outlet 23 may furthermore comprise at least one air baffle element 32, which is in particular adjustable so that the air flow 24 can be directed in different directions and/or so that the air flow 24 can be regulated.

(14) The air outlet 23 is, in particular, designed in such a way that the air flow 24 meets an area of the windshield 29 which forms a field of vision 30 of the driver (see FIG. 2). The field of vision 30 is the area of the windshield 29 through which the driver of the motor vehicle 10 must look most frequently whilst driving the motor vehicle 10. The field of vision 30 is a 30 cm wide area of the windshield 29 positioned horizontally and centrally in relation to the steering wheel 11.

(15) For receiving the air flow 24, the air duct 21 of the steering wheel 11 in particular comprises an air inlet 22, which is arranged on the rear side 18 in the steering-wheel center 13. The air inlet 22 is designed to be capable of fluid-ducting connection to the feed duct 25. The air inlet 22 has a fluid-ducting connection to the feed duct 25, particularly in the straight-ahead position of the steering wheel 11.

(16) Except at the air inlet 22 and at least the one air outlet 23, the air duct 21 is arranged inside the steering wheel 11. The air duct extends from the air inlet 22 through the steering-wheel center 13 to at least one steering-wheel spoke 14, through at least the one steering-wheel spoke 14 to the steering-wheel rim 12 and through at least one part of the steering-wheel rim 12 to the air outlet 23. The air duct 21 therefore comprises a spoke air duct as the part leading through the steering-wheel spoke 14 and a rim air duct as the part leading through the steering-wheel rim, wherein the spoke air duct opens into the rim air duct. In particular, the rim air duct extends along the entire steering-wheel rim 12. For this purpose, the air duct 21 is preferably arranged in a single steering-wheel spoke 14, which is arranged opposite the air outlet 22, that is to say in particular in the six o'clock position. The spoke air duct here opens into the rim air duct in the six o'clock position. The rim air duct is, in particular, designed as a ring, or in two runs with one run leading round to the right and the other run around to the left; both runs leading in particular to the air outlet 23.

(17) The steering wheel in particular comprises at least one thermal conduction element 16, which is designed to conduct heat energy from the air flow 24 flowing through the air duct 21 to an outer face of the steering wheel 11. The outer face is preferably the rim outer face 15. The outer face may furthermore comprise an outer face of one of the steering-wheel spokes 14, in particular a thumb rest of the steering-wheel spoke 14. The thermal conduction element 16 here is either itself part of the air duct 21, or at least partially surrounds the air duct 21.

(18) Although the steering wheel and motor vehicle have been more fully illustrated and described in detail through the preferred exemplary embodiments, they are not limited by the examples disclosed and other variants may be inferred by the person skilled in the art without departing from the scope of this document.

(19) The figures are not necessarily true in every detail or true to scale and may be represented in enlarged or reduced form in order to afford a better overview. For this reason, the functional details disclosed here are not to be interpreted restrictively but merely as a basic illustration which affords the person skilled in this field of the art guidance in how to implement the steering wheel and the motor vehicle in a variety of ways.

(20) The expression and/or employed here, when used in a series of two or more elements, means that each of the elements cited may be used singly or in any combination of two or more of the elements listed. For example, if an assemblage containing the components A, B and/or C is described, the assemblage may contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.
