An adjustment knob for rotating a horizontal vane and a vertical vane of a motor vehicle air vent is provided. The adjustment knob includes a knob body and a vane rotating portion. The knob body is coupled to the horizontal vane so as to be movable in a horizontal direction. An inserting gap, into which the horizontal vane is inserted in a frontward direction, and a receiving gap, which is enlarged from the inserting gap, are penetrated through the knob body in the horizontal direction. The vane rotating portion rotates the vertical vane by a movement of the knob body. The vane rotating portion is fixed to a rear end of the knob body below the inserting gap, and is connected to the vertical vane. The knob body is coupled to the horizontal vane such that a front end of the horizontal vane is positioned in the receiving gap and the vane rotating portion is adjacent to a rear end of the horizontal vane.

A base section can operate to one side and the other side in a predetermined direction. A contact section is attached to a spring and can be in contact with the base section. A holding section holds the spring. A wall portion faces the contact section in the predetermined direction, and generates a sound which becomes a moderation feeling by a collision between the wall portion and the contact section moved by a biasing force of the spring as a contact state between the contact section and the base section changes due to an operation of the base section. The holding section regulates a position of the spring at least in a predetermined direction. A clearance between the contact section and the wall portion is substantially equal on the one side and the other side in the predetermined direction.

A blowout structure of an air conditioner according to the present invention includes a wind direction adjuster that is arranged in a case, can change a direction of wind blown out according to a rotation angle, and closes a ventilation passage inside the case so as to inhibit blowout of the wind. Inside the case, a contact surface with which a wind direction adjuster 2 in a state of closing the ventilation passage comes into contact and a reverse surface that allows an airflow flowing back to the upstream side from the contact surface to be reversed to the downstream side.

A ventilation device for an automobile passenger compartment is provided. The ventilation device includes a control mechanism, including a drive shaft and a first and a second driven shaft for controlling a first ventilation flap. The first and second driven shafts are connected to the drive shaft by way of a coupling element, wherein the coupling element is designed as a differential.

Air vent (2) for an automotive HVAC system, having a control support vane (3) and a controlled vane (6), wherein the control support vane (3) and the controlled vane (6) are arranged in respective arrays in different orientations, the control support vane (3) supports a control member (4) connected to the controlled vane (6) which is arranged behind the control support vane (3), and at least part of the control member (4) is located at least partially within the control support vane (3).

An air vent device for a vehicle may be mounted with an upper rear wing and a lower rear wing within an air duct to be linearly movable along the front-rear direction, and be rotatably mounted with an upper air guide wing and a lower air guide wing at the front end portions of the upper rear wing and the lower rear wing, thereby controlling the wind direction of the air downward while the upper air guide wing rotates downward when the upper rear wing moves forward, or controlling the wind direction of the air upward while the lower air guide wing rotates upward when the lower rear wing moves forward.

A roof vent includes a roof disposed on a vehicle and a vent assembly. The vent assembly includes at least one vent unit disposed on the roof and configured to be popped up to the interior of the vehicle, a driving unit driving the vent unit, and at least one rack unit applying driving force of the driving unit to the vent unit. The vent unit is popped up or tilted by the driving unit.

A vent device includes at least one stage ventilation assembly, each stage of the at least one stage ventilation assembly includes an inner layer element and an outer layer element. An air duct is formed between the outer layer element and the inner layer element, and the air duct has an air duct outlet. Each stage of the at least one stage ventilation assembly has an air duct open position and closed position. The outer layer element and the inner layer element are configured to be able to move along the first direction relative to each other between the air duct open position and closed position. In the air duct closed position, the inner layer element closes the air duct outlet, and in the air duct open position, the inner layer element opens the air duct outlet.

A vehicle air register assembly includes a housing defining a cavity. An upstream portion of the cavity is disposed proximate to an inlet and a downstream portion of the cavity is disposed proximate to an outlet. Vertical vanes are disposed within the upstream portion. The vertical vanes direct air in a horizontal direction. A horizontal vane assembly is disposed within the downstream portion. The horizontal vane assembly directs the air in a vertical direction. The horizontal vane assembly includes at least one horizontal vane including a driver portion rotatably coupled to the housing proximate to the outlet and a follower portion coupled to the housing proximate to the upstream portion. The follower portion is rotatably coupled to the driver portion.

An air vent for a vehicle includes a housing with an air inlet, an air outlet, and an air channel between the air inlet and the air outlet; a rigid air directing body arranged within the air channel and pivotably arranged within the housing by being affixed to a first axis; an actuator arranged within the housing in order to act on the rigid air-directing body to determine a direction of an air stream exiting the air outlet, the actuator comprising a transmission element affixed to a second axis and pivotable around the second axis.
