A modular door for a vehicle HVAC system includes a door plate, a first shaft, and a second shaft. The door plate has a front surface extending between an upper edge surface and a lower edge surface. The upper edge surface defines a first array of keyed orifices. The lower edge surface defines a second array of keyed orifices. The first shaft has a first keyed protrusion that is disposed within a first keyed orifice of the first array of keyed orifices. The second shaft has a second keyed protrusion that is disposed within a first keyed orifice of the second array of keyed orifices. The first keyed orifice of the first array of keyed orifices and the first keyed orifice of the second array of keyed orifices form a pair of axially aligned keyed orifices.

A modular door kit for a vehicle HVAC system includes first, second, and third subcomponents. The first subcomponent defines a receptacle and is configured to be standardized for first and second door configurations. The second subcomponent has a first protrusion and is configured to be standardized for the first door configuration but not the second door configuration. The first protrusion is configured to engage the receptacle to rigidly affix the position of the second subcomponent relative to the first subcomponent to form the first door configuration. The third subcomponent has a second protrusion and is configured to be standardized for the second door configuration but not the first door configuration. The second protrusion is configured to engage the receptacle to rigidly affix the position of the third subcomponent relative to the first subcomponent to form the second door configuration.

A shaft-bearing bush assembly for a valve arrangement for an air-conditioning system is disclosed. The shaft-bearing bush assembly includes a shaft drive-connectable to a valve of the valve arrangement and a bearing bush, in which the shaft is rotatably received relative to the bearing bush between a first rotary position and a second rotary position about an axis of rotation extending along the axial direction. A bush projection is non-rotatably arranged on the bearing bush relative to the bearing bush and a shaft projection is non-rotatably arranged on the shaft relative to the shaft. The bush projection and the shaft projection are matched to one another such that the bush projection provides a rotary stop for the shaft projection for limiting the rotary movement of the shaft between the first rotary position and the second rotary position.

A modular door for a vehicle HVAC system includes a first subcomponent, a second subcomponent, and a customized subcomponent. The first subcomponent forms a first portion of the modular door and is configured to be standardized for first and second vehicle HVAC systems. The second subcomponent forms a second portion of the modular door and is configured to be standardized for the first and second vehicle HVAC systems. The customized subcomponent is configured to separate the first subcomponent from the second subcomponent. The customized subcomponent is also configured to connect the first subcomponent to the second subcomponent such that the modular door is configured for the first vehicle HVAC system.

A heating, ventilation, and air-conditioning system for a vehicle includes a housing, a door supported by the housing, and a lock integral with the housing. The housing further includes a first air flow path and a second air flow path. The door moves between a first position blocking airflow from the first air flow path and a second position blocking airflow from the second air flow path. The lock is configured to automatically lock the door in the second position upon assembly of the housing.

A valve, in particular for an air duct of an air conditioning system of a motor vehicle, having a body and having at least two bearing couplings for bearing-mounted arrangement of the valve, wherein the body has a planar extent with a first side face and with an opposite second side face, wherein the first side face is convex in design.

A HVAC unit includes a housing, at least one flap and an actuator corresponding to the flap. The housing includes a first and a second portion and defining an enclosure E. The flap is received inside the housing with a first extreme end thereof engaging with the first portion and a second extreme end thereof engaging with the second portion of the housing via an intermediate lever. The actuator disposed outside the enclosure E is connected to and drives the flap via the intermediate lever. The intermediate lever includes a stopper radially extending from at least a portion of a periphery thereof. The stopper is disposed between the second portion of the housing and the flap to limit axial movement of the intermediate lever.

An airflow door for a heating, ventilation, and air conditioning (HVAC) system. The airflow door has a first material and a second material. The first material and the second material are temperature responsive materials that change shape at different temperatures such that at a first temperature the first material and the second material are shaped to provide the airflow door with a first configuration, and at a second temperature the first material and the second material are shaped to provide the airflow door with a second configuration that is different from the first configuration.

Disclosed is an air conditioner for a vehicle, which makes it possible for an upper case and a lower case to be assembled in correct position without minute misassembly between the upper case and the lower case, thereby making operation of a sliding door smooth. The air conditioner, which includes an air-conditioning case having a plurality of cases and a door disposed inside the air-conditioning case to be able to slide, further includes: a shape-matching part where the plurality of cases are matched each other in shape; and a guide part crossing the shape-matching part to guide a sliding action of the door, wherein a cross section of the guide part at the shape-matching part is formed to be eccentric.

The present invention relates to a door of an air conditioner for a vehicle, which can prevent damage and distortion by bending during assembly and reinforce strength due to a plate-shaped sliding door with flexibility. The door of the air conditioner for a vehicle, which is disposed inside an air-conditioning case to adjust the degree of opening of an air passageway, includes: a door body formed in a plate shape and formed to be able to slide in the air-conditioning case; and a reinforcing part formed from at least one side of the door body in a thickness direction and extending in an axial direction, which is perpendicular to a sliding direction of the door body.
