A vehicle air vent apparatus according to one embodiment of the present invention is an apparatus which guides air introduced from a vehicle air conditioner into a vehicle using a direct wind mode or indirect wind mode. The vehicle air vent apparatus includes a duct part including an entrance and an exit of an air passage communicating with the vehicle air conditioner, a cover part configured to selectively close the exit of the duct part, a vent part configured to adjust a wind direction of air introduced into the vehicle through the exit of the duct part and including a rack disposed under a body of the vent part and extending in a longitudinal front-rear direction of the vehicle, and a driving part configured to change a position of the cover part and a position of the vent part according to a preset logic.

A safety ventilation device for vehicles or other applications has a housing with one or more openings covered by a hinged flap with the flaps interconnected by a connecting element. A spring is attached to the connecting element or otherwise to the flaps such that in a first position the spring keeps the flaps open and air can pass through the openings. In a second position, upon the application of force to the flaps, such as airflow caused by a moving vehicle, the spring compresses, and the flaps close. The housing of the device includes a protrusion at the top and a channel at the bottom to facilitate an interference fit between a window and a window or door frame.

An air vent assembly may include a housing configured to allow air to pass therethrough, a slit assembly disposed inside the housing and configured to control a flow direction of the air, and a knob movably connected to the slit assembly to move the slit assembly, wherein the slit assembly includes: an upper inlet plate connected to the housing, the upper inlet plate being movable along the internal surface of the housing, a lower inlet plate forming an inlet slit from the upper inlet plate and disposed inside the housing, the lower inlet plate being connected to the housing and movable along the internal surface of the housing, and an outlet plate, wherein a first side of the outlet plate is pivotally coupled to the upper inlet plate and the lower inlet plate to be movable together with the upper inlet plate and the lower inlet plate and the other side is pivotally coupled in the housing.

A duct body F30 having a straight tubular shape is provided to a duct F3 of an air conditioning function-equipped console device F1, a fin member F35 provided inside the duct body F30 faces a front blowout port F33 of the duct body F30, fin bodies F36 of the fin member F35 are arranged in an axial direction of the duct body F30, and projected areas of the respective fin bodies F36 when projected in the axial direction increase from the fin body F36 on an inflow port F31 side toward the fin body F36 on a rear blowout port F32 side. Alternatively, a damper S4 is disposed on a far side of a blowout port S2 of a duct S3 in an air conditioning duct device S1, an operation portion S5 connected to the damper S4 and partially exposed in a vehicle compartment S95 is provided, the blowout port S2 has a long shape, and at least a part of the operation portion S5 is located on an outer side in a short-side direction with respect to the blowout port S2.

A control system for an air outlet of an air conditioner in a vehicle includes a motor, a first clutch configured to control a horizontal vane of the air outlet, a second clutch configured to control a longitudinal vane of the air outlet, a third clutch configured to control an opening degree of a ventilation door of the air outlet, and an engaging element of the motor being connected to the motor, for engaging the clutches. The motor adjusts the horizontal vane of the air outlet when the engaging element is engaged with the first clutch, the motor adjusts the longitudinal vane of the air outlet when the engaging element is engaged with the second clutch, and the motor adjusts the opening degree of the ventilation door of the air outlet when the engaging element of the motor is engaged with the third clutch.

An air outlet assembly for airflow in a vehicle interior is disclosed. The air outlet assembly may comprise a housing providing an outlet, a vertical guide assembly to guide airflow toward the outlet, and a diverter to guide airflow through the outlet. The diverter may to direct air from an inlet of the housing to the vertical guide assembly. The vertical guide assembly may comprise a set of vertical guides that pass through the diverter. The diverter may surround the set of vertical guides. The diverter may comprise a rear portion between an inlet of the housing and the set of vertical guides and a front portion between the set of vertical guides and the outlet. The diverter may translate relative to the set of vertical guides; the set of vertical guides may rotate relative to the diverter.

Disclosed is an air vent comprising a housing configured to guide an air flow from an air inlet to an air outlet, an air guide arranged at least partly within the housing such that the air guide and the housing define a first air channel and a second air channel, a regulating flap arranged between the air inlet and the air guide, configured to regulate a ratio between a first partial air flow through the first air channel and a second partial air flow through the second air channel, a first and second shutoff element arranged at least partly within the housing. The first shutoff element is configured to shut off the first partial air flow without shutting off the second partial air flow and the second shutoff element is configured to shut off the second partial air flow without shutting off the first partial airflow.

An air outlet device for an air conditioner includes a housing that also serves as an air outlet, swingable fins supported by the housing, a pinion gear portion that can swing with the fins, a rack gear portion that meshes with the pinion gear portion, and an operation portion that can linearly move with the rack gear portion. When the fins are swinging to a maximum swingable angle, a rack tooth portion of the rack gear portion, which meshes with the pinion gear portion, is a rack large tooth portion that is formed larger than the adjacent rack tooth portions.

An air vent (1) for a motor vehicle, wherein the air vent (1) includes a housing (2) having an air inlet region (3) and an opposite air outlet region (4). In the housing (2) of the air vent (1), an airflow splitter (5), which extends at least regionally or partially transversely to the housing longitudinal direction, is arranged such that a first air guiding region (6) and a second air guiding region (7) are formed, wherein, for the purpose of air deflection as needed in a first direction, in particular in a vertical direction, the air vent (1) includes a device for airflow control, via which device a portion of the total airflow flowing through the housing (2), the portion flowing through the first and/or second air guiding region (6, 7), is adjustable.
