Described herein is an air intake device for an air conditioning unit of a vehicle, the air intake device including a casing on which there are formed a fresh air inlet, a recirculation air inlet, and an air outlet adapted to be associated to an air inlet of a blower of the air conditioning unit, and a pair of drum flaps mounted to the casing and rotatable about a common rotation axis and movable between a fresh air extreme position and a recirculation extreme position. In the fresh air extreme position, the angular span of the recirculation air inlet is partially covered by one of the drum flaps and partially covered by the other of the drum flaps, and in the recirculation extreme position, the angular span of the fresh air inlet is completely covered by one of the drum flaps, the drum flaps overlapping each other.

A flap stopper for a rotatable flap for controlling an air flow may include a round bearing support disc, a round stopper support disc, stop elements, and connecting ribs. The stopper support disc may be spaced apart from the bearing support disc in an axial direction. The stop elements may be arranged on the stopper support disc. The connecting ribs may be arranged between the bearing support disc and the stopper support disc. The bearing support disc, the stopper support disc, the stop elements, and the connecting ribs may be formed as an integral plastic injection-molded part.

A closable air vent may be bonded to a laminated or tempered windshield used on UTV or other types of vehicles. The air vent may include a vent body with a flap opening and a bond channel, a flap pivotably secured in the flap opening on a flap pivot, and an actuator coupled with the flap via a roll pin and displaceable between a flap closed position and a flap open position. In the flap closed position, the roll pin is disposed on one side of the flap pivot, and in the flap open position, the roll pin is disposed on an opposite side of the flap pivot.

An air distribution plenum for controlling air flow in a vehicle HVAC system includes an air inlet and first and second air outlets. A movable member substantially blocks the first and second air outlets when in a first position, blocks only the first air outlet in a second position, blocks only the second air outlet in a third position, and permits air to flow through both the first and second air outlets when in a fourth position.

A flap system for a heating, ventilation and air-conditioning unit for circulating-air/fresh-air control in a motor vehicle, the HVAC unit having flow ducts for circulating air and for fresh air and a mixing chamber in which circulating air and fresh air are mixed with one another for ventilating a vehicle interior, the flap system having two rotary flaps, each adjustable about an axis of rotation, and an actuator, by which one of the two rotary flaps is driven directly for adjustment, and wherein the other rotary flap is a circulating air rotary flap associated with the flow channel for circulating air for influencing a circulating air flow.

The present invention relates to an electric actuator (50) suitable for driving a movable element for a heating, ventilation and/or air conditioning system for a motor vehicle, including an electric motor (2) comprising a stator (3), a rotor (4) extending along an axis (X), a pinion (5) rigidly connected to the rotor (4), a drive mechanism (6) comprising: a planet carrier (7), at least one planet gear (8) held by the planet carrier (7), the planet gear (8) being suitable for being rotated by the pinion (5), an output ring gear (11) suitable for being rotated by the at least one planet gear (8), a drive socket (12) rigidly connected to the output ring gear (11) and suitable for driving the movable element, the drive socket (12) being at a distance from the electric motor (2) along the direction of the axis (X) of the rotor (4).

A bearing arrangement has a bearing pin and a coupling pin, and a second bearing component, which components are mounted on a wall so as to be rotatable about a common axis of rotation. The bearing pin extends along, and the coupling pin extends eccentrically to the axis of rotation. The bearing pin is accommodated in a bearing opening of the wall. The coupling pin is accommodated in a guide slot of the wall and projects from the guide slot. The second bearing component has a first opening, in which the bearing pin is accommodated, and a second opening arranged eccentrically to the first opening, in which second opening the coupling pin is accommodated. The bearing pin is connected to the second bearing component via a lock, and the second bearing component is supported on the coupling pin.

An air-conditioning system may include at least one outlet for discharging an air current into the space, first and second distribution elements for adjusting differing first and second parameters of the system, the first and second distribution elements adjustable over first and second adjusting ranges, respectively, and a cam plate for adjusting the distribution elements and featuring first and second guide structure for adjusting the first and second distribution elements, respectively. The guide structures may be configured such that the first distribution element remains in a predefined position over a predefined first angular range of rotation of the cam plate, and the second distribution element may be adjusted in dependence on a rotational angle of the cam plate in the first angular range of rotation. The first distribution element may be adjusted when the second distribution element is in a predefined position at an end of the second adjusting range.

A ventilation device may include first and second supply ducts, a mixing section having a mixing duct into which the first and second supply ducts may lead, the first and second supply ducts arranged in the mixing section adjacent one another in a transverse direction, and first and second guides in the mixing section each running in the transverse direction and being located opposite one another in a longitudinal direction running transversely to the transverse direction, each guide having two guide walls running in the transverse direction and located opposite one another in a height direction running transversely to the transverse direction and longitudinal direction, at least one of the guide walls sloping away from the other guide wall at a slope angle with respect to the longitudinal direction. A valve may have a plate body and may be adjustably guided with a first guide section running in the transverse direction in the first guide and with a second guide section running in the transverse direction in the second guide. An actuator may during operation adjust the valve in the transverse direction between a first position, in which the valve fluidically separates the second supply duct from the mixing duct and opens a fluidic connection between the first supply duct and the mixing duct, and a second position, in which the valve fluidically separates the first supply duct from the mixing duct and opens a fluidic connection between the second supply duct and the mixing duct, wherein the first guide section has a first thickness running in the height direction and which is smaller than a second thickness of the second guide section running in the height direction in such a manner that both guide sections are each in contact with both guide walls of the associated guide.

A ventilation system for a vehicle can include a roll over protection system. The roll over protection system can include a bar. The ventilation system can have an air duct configured to selectively attach to and detach from the bar.
