The air moving device (21) can be or is mounted to an area remaining static in relation to an adjustment movement of the steering device (2). The handle distributor (26) can be or is mounted to an area moving in relation to the static area when the steering device (2) is subject to an adjustment movement. The climate control device (15) is provided with a connecting device (30) allowing the air moving device (21) and the handle distributor (26) to move in relation to each other. ## Claims ### Claim 1 A climate control device for influencing at least one climatic parameter of a handle of a steering device comprising: an air moving device configured to be within a static portion of the steering device; a handle distributor configured to be within at least a part of the handle of a moveable portion of the steering device; a connecting device fluidly coupling the static portion of the steering device to the moveable portion of the steering device; a plurality of air guidance devices located on the static portion and the moveable portion of the steering device that fluidly connect the air moving device and the handle distributor through the connecting device; and at least one thermoelectric device fluidly connected with the air moving device and the handle distributor to heat the handle of the steering device in a heating mode and cool the handle of the steering device in a cooling mode; wherein the plurality of air guidance devices directs a stream of air to and from the static portion of the steering device and the handle distributor through the connecting device without inhibiting the stream of air when the moveable portion of the steering device rotates relative the static portion of the steering device; wherein the connecting device includes at least two interfaces between the static portion and the moveable portion of the steering device creating two air paths allowing an exchange of at least two air streams between the handle distributor and the connecting device, at least a first air stream being directed toward the handle distributor and at least a second air stream being directed away from the handle distributor wherein the connecting device is provided with a ring connector channel arranged concentrically in relation toward an axis of a pivot pole. ### Claim 2 (depends on 1) The climate control device according to claim 1, wherein the connecting device allows a rotation of the handle device of at least 180° around the pivot pole of the steering device. ### Claim 3 (depends on 1) The climate control device according to claim 1, wherein at least a first air path is provided for moving the first air stream along a first side of the at least one thermoelectric device, and at least a second air path is provided to moving the second air stream along a second side of the at least one thermoelectric device, the first side and the second side having a different temperature during the heating mode and the cooling mode. ### Claim 4 (depends on 1) A handle, vehicle, or steering mechanism, equipped with at least one climate control device according to claim 1. ### Claim 5 (depends on 1) The climate control device according to claim 1, wherein the steering device is a steering wheel. ### Claim 6 A climate control device for a steering device comprising: a. one or more connecting devices located between and fluidly connecting a static component of the steering device with a movable component of the steering device, the one or more connecting devices including: i. a static part; ii. a movable part fluidly connected to the static part, iii. one or more inlet channels from the static component of the steering device to the movable component of the steering device that guide a fluid towards the moveable component of the steering device from the static component of the steering device; and iv. one or more outlet channels from the movable component of the steering device to the static component of the steering device that guide the fluid towards the static component of the steering device from the movable component of the steering device; b. one or more air movers located within the static component of the steering device and being in fluid communication with the movable component of the steering device through the one or more connecting devices; wherein the movable part of the one or more connecting devices moves with the movable component of the steering device so that the one or more inlet channels and the one or more outlet channels has a static relationship with the movable component as the movable component of the steering device is moved; and wherein the one or more air movers simultaneously blows fluid through the one or more inlet channels into the movable component of the steering device and through the one or more outlet channels away from the steering device. ### Claim 7 (depends on 6) The climate control device of claim 6, wherein each of the one or more inlet channels and the one or more outlet channels are discrete from one another. ### Claim 8 (depends on 6) The climate control device of claim 6, wherein the one or more connecting devices includes two discrete halves that are separated by a dividing wall. ### Claim 9 (depends on 8) The climate control device of claim 8, wherein an air guidance device is connected to the one or more inlet channels and the one or more outlet channels for guiding air between the static component of the steering device and the movable component of the steering device. ### Claim 10 (depends on 9) The climate control device of claim 9, wherein one or more seals are located between the static part and the movable part and the one or more seals form a fluid barrier and create a bearing surface of the movable part to move about the static part. ### Claim 11 (depends on 10) The climate control device of claim 10, wherein the connecting device includes one or more end walls and the end walls include one or more of the inlet channels, outlet channels, or both. ### Claim 12 (depends on 11) The climate control device of claim 11, wherein the static component of the steering device is a steering column and the movable component of the steering device is a steering wheel. ### Claim 13 (depends on 3) The climate control device of claim 3, wherein the first air path and the second air path are discrete from one another. ### Claim 14 (depends on 13) The climate control device of claim 13, wherein the connecting device includes two discrete halves that are separated by a dividing wall. ### Claim 15 (depends on 14) The climate control device of claim 14, wherein one or more seals are located between the static part and the movable part and the one or more seals form a fluid barrier and create a bearing surface of the movable part to move about the static part. ### Claim 16 (depends on 15) The climate control device of claim 15, wherein the connecting device includes one or more end walls and the end walls include one or more inlets, one or more outlets, or both. ### Claim 17 (depends on 16) The climate control device of claim 16, wherein the static component is a steering column and the movable component is a steering wheel. ### Claim 18 (depends on 6) The climate control device of claim 6, wherein the movable part extends over and receives the static part of the one or more connecting devices.
