Preferably, at least one steering mechanism has at least one handle 5 . A handle means a device for gripping and exerting an adjusting force, in particular for manually adjusting the steering of a door or for operating an electric motor.

In addition, the present invention also relates to a climate control device 15 . Climate control device means an object suitable for influencing at least one climate parameter of the area to be influenced, for example for heating, ventilation, humidification or dehumidification and/or cooling.

Preferably, at least one climate control device 15 has at least one temperature control device 17 . A temperature control device means a device for precise temperature control of a user or an object to be heated, especially for raising, maintaining or lowering the temperature, such as a heating, cooling or ventilation device.

Furthermore, the invention relates to a heating device 16 which preferably represents a temperature control device 17 or a component thereof. A heating device means a device that provides thermal energy for specific heating of its environment and emits this energy to its environment conductively, convectively and/or by thermal radiation. Examples are installations with at least one resistance heater, heat pump, radiator or heating coil, there may also be a plurality or different types of these components. It is advantageous if the planar heating element 16b is arranged in the housing for heating the handle surface and additionally the Peltier element 16a or PTC heating element is arranged in the airflow for heating the airflow directed to the steering device 2 .

Preferably, at least one heating device 16 has at least one heating resistor for direct or indirect heating of the handle. A heating resistor implies an ohmic resistor or other electrical component that converts electrical energy into heat when an electric current passes through it. Examples are heating segments made of carbon fibers, PTC heating elements connected in the airflow, layers made of electrically conductive plastics such as those made of aluminum foil or especially handle surfaces made of metal wires Individual large-area heating sections within the clamping zone.

Preferably, at least one temperature control device has at least one cooling device 19 for removing excess heat energy, in particular generated by sunlight. A cooling device means a device that lowers the temperature of a surface to be cooled or an object to be cooled, such as a Peltier element, a heat-conducting pipe, or a ventilation device such as a fan. A location at a distance from the temperature control zone facilitates simple assembly and reduces construction space, for example behind the fan in the direction of flow, in particular close to or within the pivot rod of the steering mechanism. A fan with an integrated Peltier assembly is advantageous for a modular combination of fan and cooling device.

Preferably, at least one heating or cooling device has at least one ventilation device 20 . Ventilation device means a device that can be used to precisely change the air composition or air flow within a specific two-dimensional or three-dimensional area.

Preferably at least one ventilation device has at least one air displacement device 21 . Air moving device means a device for moving air. Examples are fans, especially radial fans, or car air conditioners.

Preferably, at least one ventilation or air conditioning device has at least one air guiding device 22 . Air guiding device means a device capable of guiding air in at least one direction between the zone to be conditioned with air and the air feed device or along the zone to be ventilated.

Preferably, at least one ventilation device exhibits at least one handle distributor 26 for ventilation or back ventilation of the handle. By handle distributor is meant a device for collecting, distributing and/or directing air in or along the handle, such as a duct or gap connecting one or more attachments or vents to each other.

Preferably, the air guiding device 22 has at least one connection device 30 for movably connecting the ventilation device 20 with the handle distributor 26 . The connecting device 30 preferably has a disc-like shape. Preferably, its central axis coincides with the pivot rod 3 . Preferably, it is arranged in a plane perpendicular to the pivot rod 3 .

The connecting device 30 is provided with at least two independent parts 31' and 32', at least one of which is movable relative to the other by sliding or pivoting. One part 31' supplies air and the other part 32' receives air. Which supplies and which receives depends on the direction of the passing airflow. Thus in case the air flow is switched to the opposite direction, the part should also have a corresponding opposite function.

Preferably, the connecting device 30 has a supply portion 31 for supplying air, generally corresponding to one portion 31 ′, and a receiving portion 32 for receiving air, generally corresponding to at least a second portion 32 ′. At least one of those parts can move relative to the other part without significant loss of air. Relative movement between those parts is thus possible while substantially the entire supply air of the supply part 31 is delivered to the receiving part 32.

The two parts 31' and 32' share at least one joint interface 40 to exchange air therebetween. To this end, the portions 31 ′ and 32 ′ are at least partially open towards each other along the joint interface 40 . This opening enables air to pass from one of the portions 31 ′, 32 ′ to the other perpendicular to the axis of the pivot rod 3 , if the interface 40 is arranged at least partly along a cylindrical surface coaxial with the pivot rod 3 .

If the interface 40 is arranged at least partially along a plane perpendicular to the axis of the pivot rod 3, as in FIGS. 3 the direction of the axis. Especially in this case, preferably, the two parts engage with each other in order to improve the airtightness of their connection. This can be achieved, for example, by plugging them into each other during assembly by movement along the axis of the pivot rod 3 .

Preferably at least one supply portion 31 has at least one supply channel 33 to supply air along at least a part of the relative movement path. It is preferably a circular channel with a rectangular or trapezoidal cross-section and one open side.

Preferably, at least one receiving portion 32 has at least one collecting channel 34 to collect air along at least a part of the relative movement path. At least a part of its cross-section corresponds to at least a part of the cross-section of the supply channel 33 . It is preferably a circular channel with a rectangular or trapezoidal cross-section and one open side facing the open side of the supply channel 33 .

Preferably, the supply portion 31 and/or the supply channel 33 has an exhaust opening 35 represented eg by one or more openings. It can be, for example, round, rectangular or elongated in form. Preferably, it is ring-shaped, the center of which is arranged on the pivot rod 3 of the steering device 2 .

Preferably, the receiving portion 32 and/or the collecting channel 34 has an air inlet 36 represented, for example, by one or more openings. It can be, for example, round, rectangular or elongated in form. Preferably, it is ring-shaped, the center of which is arranged on the pivot rod 3 of the steering device 2 .

In a preferred embodiment, the feeding channel 33 of the feeding part 31 and the collecting channel 34 of the receiving part 32 are at least separated from the common connecting channel 37 . Although slidable or pivotable relative to each other, the two parts work together to keep the pilot air within the common connection channel and not allow it to escape the boundary between the two parts.

In order to enable a smooth relative movement between the parts 31 and 32 at least one rolling element 38 is arranged between at least one boundary wall of the supply part 31 and at least one boundary wall of the receiving part 32 . Preferably, a plurality of rolling elements 38 are provided along the joint boundary wall of the common connecting channel 37, preferably on both sides thereof so as to be on the inside and outside relative to the pivot rod 3.

The rolling elements 38 preferably have a spherical, cylindrical or conical form. To save space, cylindrical rolling elements are preferred.

In order to prevent air exchange between the rolling elements, the connecting device 30 is preferably provided with one or more sealing devices 39 such as seals or gaskets. Such sealing means 39 are preferably positioned along the arrangement of the rolling elements (eg bearings) or parallel thereto.

Preferably radial ventilators are used as air moving means 21 . It is mounted in a zone that is stationary with respect to the adjustment movement of the steering device 2 . A temperature control device 17 is provided at the discharge side of the air moving device 21 . It can also be arranged in or connected to the air guiding device 22 or further along the air path to the air moving device 21 . The temperature control device 17 may be a first thermal resistor, such as a PTC heater, mounted to heat the air flow of the air moving device 21 .

Preferably, the temperature control device is a thermoelectric device 16a to selectively heat or cool the exhaust air.

Preferably, an air moving device 21 is attached to one side of the thermoelectric device 16a to provide an air flow with heating or cooling energy.

Preferably, the temperature control device 17 is connected to one or more connecting devices 30 via two or more tubes or channels. This creates multiple airflows and works as one or more air guiding devices 22 between the temperature control device 17 and the one or more connection devices 30 .

Preferably, one or more air guiding devices 22 are connected to one or more distributors 31 and/or supply channels 33 or one or more connecting devices 30 . The air flow in the air guiding device 22 is perpendicular to the direction in the supply channel 33 .

If two or more air guiding devices are connected to the same supply channel 33 , their connection points are preferably separated from each other in order to improve a uniform air distribution in the supply channel 33 . If the supply channel has the form of a ring, the connection points are preferably separated from each other by a number of degrees, essentially corresponding to 360° divided by the number of connection points or the number of connected air guiding devices 22 . The two connection points are therefore approximately 180° apart from each other in this example.

The supply channel 33 of the supply part 31 in this example also forms the collection channel 34 of the receiving part 32 . In this section, the resulting air flow thus forms a ring-shaped hollow space representing the common connecting channel 37 . It enables the air to move along the axis of the pivot rod 3 and the air to move around the pivot rod 3 .

Receptacle 32 and/or collecting channel 34 are preferably connected via one or more tubes (which represent further air guiding means 22 ′, 22 ″′) to steering device 2 and/or to handle distributor 26 in handlebar 5 .

In order to be able to distribute the air evenly within the handle 5, the air flow can be divided via a plurality of air guiding devices 22'. Preferably, their number is similar to or higher than the number of air guiding means 22 between the air moving means 21 and the connection means 30 . Preferably, they are up to double in number to be able to distribute the air along the handle 5 in more than one direction.

Preferably, the climate control device 15 is provided with more than one connection device 30 . Preferably, the climate control device 15 and/or the connection device 30 can additionally or alternatively be provided with more than one supply 31 and/or reception 32 . This allows to increase the supply volume obtained by multiple parallel gas streams.

Sometimes it is also preferable to have the climate control device 15 and/or the connection device 30 have two or more air flows that allow simultaneous, in particular reverse directions. An air flow can then be directed from the air displacing device 21 towards the handle 6 and distributed in the handle distributor 26 . At the same time, a return airflow can be directed from the handle distributor 26 back towards the parallel second connection means, the second interface 40' or the second connection channel 37'. The air flow can then be directed towards the second side of the thermoelectric device 16a via the other guiding means 22"'. It can thus remove unwanted waste heat or cold from the thermoelectric device 16a as an exhaust flow. It can then be removed in a place out of the way (e.g. The discharge thereof takes place, for example, via an outlet pipe, in the foot area of the passenger compartment or outside the vehicle 1 .

Preferably, the climate control device 15 is fitted with two air moving devices 21 . Preferably, the first air moving device 21' is associated or coupled to the first side of the thermoelectric device 16a. Preferably, the second air moving device 21" is associated with or coupled to the second side of the thermoelectric device 16a. The temperature of the first side and the second side of the thermoelectric device 16a is different during operation. The first air moving device 21' is set to Air is moved towards the steering wheel. The second air moving device 21" is arranged to move exhaust air away from the steering wheel and towards the vehicle floor or some exhaust outlet (eg via the vehicle's HVAC (heating/ventilation/air conditioning) system).

The first air moving device 21' is connected to the handle dispenser 26 via the connection device 30 and the supply pipe 22a. Preferably, the first air moving device 21' is a radial ventilator and the supply pipe 22a, the connecting device 30 and the handle distributor 26 are coupled to the air outlet of the air moving device 21'. In this arrangement, the handle distributor preferably has no air outlet openings towards the driver's hand. Conversely, air entering the handle distributor 26 via the supply duct 22a passes through the handle distributor 26 and is subsequently removed via the recirculation duct 22b. The recirculation duct 22b is coupled with the first air moving device 21 ′ via a connection device 30 . Preferably, the recirculation duct 22b is connected to the air inlet of the air moving device 21'. One side of the thermoelectric device 16a, responsive to the thermal properties of the handle dispenser, is thus coupled to the airflow forming an at least partially closed circuit to recirculate the air. In this way, if the thermoelectric device 16a is used for heating, the heating performance of the climate control device is increased. Because the already warmed air is recirculated towards the warm side of the thermoelectric device 16a. If the climate control is used for cooling, then the cooling performance is increased. Because the cold side of the thermoelectric device 16a is provided with already precooled air from the handle distributor 26. Preferably, both the first and second air moving means 21', 21" are connected to the thermoelectric device. Preferably, they are coupled to different ends of the thermoelectric device 16a. The resulting two airflow directions are thus different. Preferably, they are mutually on the contrary.

The first air moving device 21 ′ may have an air intake device 92 . The air intake device 92 is coupled to the air intake of the first air moving device 21'. Air intake 92 has a recirculation inlet 95 coupled to recirculation conduit 22b. Thus, this recirculation inlet 95 connects the handle distributor 26 with the air inlet of the first air moving device 21'. The air intake device 92 may further include a second air intake port 94 . Via this air inlet 94 the air circuit is connected to the ambient air. Via the second air inlet 94 the first air moving device 21 ′ can thus be supplied with ambient air in addition to the recirculated air. This eliminates air loss or makes it easier to adjust the supply volume and air pressure within the fluid circuit.

It is therefore advantageous for the climate control device 15 to have an air moving device 21 provided with a first air exchange opening 97 connected to the handle distributor 26 via at least one supply pipe 22a and a connecting device 30, wherein:

- the air moving device 21 is provided with a second ventilation port 98,

- the climate control device is provided with at least one recirculation duct 22b, which connects the handle distributor 26 with the second air inlet 98 via the connection device 30, and

- The climate control device 15 is thus provided with a channel circuit for circulating air between the air moving device 21 , the thermoelectric device 16 a and the handle distributor 26 .
