The present disclosure provides a power transmission device in which stress is reduced and a vehicle air-conditioning device. An air-conditioning device has an inside/outside air door. A power transmission device drives the inside/outside air door. The power transmission device has a motor, a gear train, and a cam mechanism. A first gear of the gear train provides a rotatable member. A plurality of lock mechanisms is provided, which stops a rotation of the first gear at one end and/or the other end in a rotation direction of the first gear. The plurality of lock mechanisms provide a plurality of contacts between the first gear and a stationary link cover.

A ventilation device of a vehicle includes an air outflow opening disposed on an upper side of a backrest of a seat of the vehicle such that an airflow from the air outflow opening flows in a direction of a roof of the vehicle. A plurality of air guiding elements are pivotably mounted in a region of the air outflow opening where an air volume of a front partial airflow and a rear partial airflow is settable by the plurality of air guiding elements. A further air guiding element is disposed on the roof in a region of the airflow where the airflow is dividable and deflectable by the further air guiding element.

An inlet subassembly for a heating, ventilation, and air conditioning (HVAC) system. The inlet subassembly includes a divider defining a first airflow path and a second airflow path on opposite sides of the divider. The first airflow path extends from a first side of the recirculation air inlet and a first side of the fresh air inlet. The second airflow path extends from a second side of the recirculation air inlet and a second side of the fresh air inlet. A first inlet door is movable to control airflow into the first airflow path from the first side of the recirculation air inlet or the first side of the fresh air inlet. A second inlet door is movable to control airflow into the second airflow path from the second side of the recirculation air inlet or the second side of the fresh air inlet.

A motor-vehicle includes one or more electrically-operated valves, arranged on the structure of the motor-vehicle in a lower position with respect to the windows, for providing a communication between a passenger compartment and the external environment, and one or more electronic control units programmed to activate a ventilation mode of the passenger compartment when the motor-vehicle is parked with the engine off, even with the driver outside the vehicle. The ventilation mode includes controlling at least partial opening of one or more windows and the opening of one or more of the valves to generate a flow of natural air from the bottom upwards through the passenger compartment of the motor-vehicle.

A vehicle trim element having at least one functional component and at least one aerator of the vehicle compartment. The aerator includes at least one duct for conveying a gas flow defining an opening for diffusing the gas flow, the conveying duct extending in a main direction. The aerator is arranged to diffuse a gas flow in the passenger compartment of the vehicle in a diffusion direction in which the gas flow is diffused and which is variable by Coanda effect, between a first diffusion direction and a second diffusion direction that is different from the first diffusion direction. The opening for diffusing the gas flow extends around the periphery of at least one portion of the functional component.

The invention provides an alternative electrical charging system for a vehicle which is at least partially powered by electricity. The system employs a wind driven generator which produces electricity in response to air motion. When the generator is operating, electricity is communicated the battery of the vehicle. Operation of the generator involves a controller that monitors the electrical status of the battery and selectively activates a fan or opens a ducting system communicating with the generator. The controller also, in some embodiments, monitors the motion and the attitude of the vehicle.

An air venting system includes, among other things. A box of a truck. The box provides a cargo area. The system further includes a cab back panel of the truck. The cab back panel has an exposed section that provides a front wall of the cargo area. The cab back panel has a hidden section outside the cargo area. An air extractor is held within the hidden section of the cab back panel.

A ventilation member of the present disclosure comprises: a support having a through hole that serves as an air passage between inside and outside of a housing upon attaching the support to an opening of the housing; and an air-permeable membrane disposed on the support and closing the through hole. The support comprises: a supporting portion in which the through hole is provided and at which the air-permeable membrane is disposed, and an insertion portion extending from the supporting portion and having an end with a hook, wherein the insertion portion bends in a direction closer to a central axis of the ventilation member while the hook is passing through the opening by being inserted into the opening, and fixes the ventilation member to the opening with the hook engaging the housing after passing through the opening. The ventilation member has a stopper portion with which bending of the insertion portion in the direction is restricted within an elastically deformable range of the insertion portion during the insertion into the opening. A ventilation member of the present disclosure can be reliably fixed to an opening of a housing with the insertion portion, even when the insertion portion is inserted into the opening at an angle.

The present invention relates to an air conditioner for a vehicle, which includes a cold air passageway and a warm air passageway, and two blowers disposed in the air passageways, thereby rapidly ventilating the interior of the vehicle using the two blowers.

An on-vehicle air conditioner includes a suction port disposed on a ceiling of a vehicle cabin to suction air within the vehicle cabin, a door discharge port disposed at an upper end of a door opening portion located on a wall face of the vehicle to discharge air downward, and an upper duct configured to guide to the door discharge port the air suctioned by the suction port.
