An air vent for a vehicle includes a housing with an air duct bounded by the housing, at least one shut-off flap which is adjustable between a closed position and an open position within the air duct and has a flap body and a sealing edge which at least partially surrounds the flap body for butting against a sealing surface of the housing in the closed position, wherein the sealing edge is composed of the same material as the flap body and has a lower rigidity than the flap body.

This vehicular air conditioning device includes: an evaporator; a heater core; a unit case including a cooling space configured to accommodate the evaporator, a heating space connected to the cooling space and configured to accommodate the heater core, an air mixing space connected to the cooling space and the heating space, and a foot outlet flow channel; an air mixing damper provided among the cooling space, the heating space, and the air mixing space, and configured to rotate between a maximum cooling position (Pc) and a maximum heating position (Ph) to adjust a ratio of air to be introduced into the air mixing space; and a foot switching damper capable of partitioning the air mixing space and the foot outlet flow channel. The air mixing damper includes a reheat preventing damper having a principal plane. The foot switching damper does not protrude further toward the air mixing space side than an imaginary plane including the principal plane.

A control damper for a housing of an air-handling unit includes a rigid main body rotatable about a first rotational axis. A sealing element extends radially outwardly from a first side of the rigid main body. The sealing element is formed of a resilient material. The sealing element further includes a resilient lip extending outwardly from a distal end thereof. The lip has a first series of undulations formed in an outer edge thereof, wherein the undulations form a wave-shaped profile in the outer edge of the lip.

A vehicular air conditioning device includes a damper and a unit case in which a shaft receiving hole is formed for supporting the damper. The damper includes a rotating shaft portion extending in an axial direction, and a plate-like first damper body extending from the rotating shaft portion. The rotating shaft portion includes a flange portion provided at only a partial region in the circumferential direction of the axis. The inner wall surface of the unit case includes an elongated protrusion, with which a first damper plate surface of the first damper body is contactable from another side in the circumferential direction, and a contact portion with which a second damper plate surface of the first damper body is contactable from one side in the circumferential direction. A radial space between a radially inward end part of the elongated protrusion and a shaft receiving hole is less than a radial size of the flange portion.

An air handling system for a heating, ventilating, and air conditioning system comprises a housing including a sealing surface, a door wall disposed in the housing having a perimeter, and a sealing element disposed about the perimeter of the door wall. The sealing element includes a base, a stem, and a tip. The base is coupled to the perimeter of the door wall, the stem is formed between the base and the tip, and the tip is configured to selectively engage the sealing surface of the housing. A plurality of dentil features project from the stem of the sealing element and is arranged in a linear array extending parallel to the perimeter of the door wall. The array of the dentil features is configured to reduce an incidence of whistling when a flow of air passes by the tip of the sealing element.

An air conditioning unit for a vehicle has a casing, a heating heat exchanger, a first partition plate, a first opening, a second partition plate, a second opening, and a switching door. The casing has a face opening and a foot opening. The heating heat exchanger is arranged in the casing. The first partition plate partitions a downstream side of the heating heat exchanger in an airflow direction into a first passage and a second passage located below the first passage. The first opening is formed on a downstream side of the first partition plate in an airflow direction and communicates between the first passage and the second passage. The second partition plate is arranged on the downstream side of the heating heat exchanger and is formed with a third passage between the first partition plate and the second partition plate in the first passage. The second opening that is located on a downstream side of the second partition plate in an airflow direction and communicates between an upper side and a lower side of the second partition plate. The switching door opens or closes the first and second openings. The air in the third passage is guided toward the foot opening by the second partition plate and the switching door in an air conditioning mode in which the switching door opens the first opening and closes the second opening.

The passage opening and closing device includes a casing in which an opening edge forms an opening of an air passage, and a sliding door slidably movable inside the casing to open and close the opening. A door end part of the sliding door faces a door facing wall of the opening edge when the sliding door is positioned at a closed position where the sliding door closes the opening. A gap flow-path extending in the door moving direction is formed between the door facing wall and the door end part. A distance between the door end part and the door facing wall decreases downstream in air flow in the gap flow-path so that the gap flow-path is a convergent flow path.

This vehicular air conditioning device includes: an evaporator; a heater core; a unit case including a cooling space configured to accommodate the evaporator, a heating space connected to the cooling space and configured to accommodate the heater core, an air mixing space connected to the cooling space and the heating space, and a foot outlet flow channel; an air mixing damper provided among the cooling space, the heating space, and the air mixing space, and configured to rotate between a maximum cooling position (Pc) and a maximum heating position (Ph) to adjust a ratio of air to be introduced into the air mixing space; and a foot switching damper capable of partitioning the air mixing space and the foot outlet flow channel. The air mixing damper includes a reheat preventing damper having a principal plane. The foot switching damper does not protrude further toward the air mixing space side than an imaginary plane including the principal plane.

The present invention relates to a vehicle air conditioning device capable of improving sealing ability by doubly sealing a defrost vent of an air conditioning case, and increasing the amount of airflow discharged inside a vehicle while simultaneously preventing an increase in the amount of force needed to actuate a face door and, more particularly, to a vehicle air conditioning device comprising: a ball; the air conditioning case in which a floor vent is formed; a defrost door installed to be rotatable via rotation shafts respectively inside the air conditioning case, and opening and closing each of the vents; the face door; the defrost vent for discharging air entering through the floor door and an air inlet inside the air conditioning case; and a face vent (in the passage of which an evaporator and a heater core are installed in that order), wherein the vehicle air conditioning device is characterized in that the face door is configured to doubly seal the defrost vent.

An air-conditioning register includes a retainer having an airflow passage, and a shut-off damper, which is pivoted about a damper shaft between opening and closing positions for the airflow passage. The shut-off damper has opposed side sections, which are opposed to each other with the damper shaft located therebetween, and a distal sealing portion. The distal sealing portion includes a curved surface and a planar surface. The curved surface is arranged on the trailing side in a pivoting direction of the shut-off damper towards the closing position. The planar surface is arranged on the leading side in the pivoting direction in a manner defining an acute angle with respect to an opposing direction of the opposed side sections. At least the planar surface is a textured surface having raised features each having a height of 110 m50 m.
