NAME AND ADDRESS OF THE APPLICANT:
TATA MOTORS LIMITED, having address at Bombay House, 24 Homi Mody Street, Hutatma
Chowk, Mumbai 400001 Maharashtra, India.
Nationality: INDIAN
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD:
Present disclosure generally relates to a field of air vent assemblies of a heating, ventilating, and air conditioning [HVAC] unit. Particularly, but not exclusively, the present disclosure relates to an air vent assembly for selectively redirecting air flow from an air conditioning unit of a vehicle in various directions.
BACKGROUND OF DISCLOSURE:
With economic development and urban expansion, people’s commuting distances are increasing, so the time spent on public transportation is increasing. Automobiles such as buses are one of the most used means for public transport. Some of the vehicles used for public transport in urban areas include air conditioning systems for improving thermal comfort to the passenger. The air conditioning unit is configured to provide hot or cool air that is directed into a passenger cabin of the vehicle through a blower unit connected to the air conditioning system. The passenger cabin of such vehicles are designed to have a less seating capacity to accommodate a greater number of passengers who commute standing. Typically, the air conditioning system is mounted on a roof of the vehicle and conditioned air is directed by the blower unit through a conduit. The conduit extends on either sides of the passenger cabin along a length of the vehicle. A plurality of vents are defined on various positions of the conduit for directing the conditioned air onto seats of the vehicle arranged at either sides of the vehicle to provide thermal comfort to the passengers.
During peak hours, the number of passengers using the public transport increases. This requires a greater number of passengers to be standing throughout the journey. Since, the plurality of vents of the air conditioning system are configured to direct the conditioned air only towards the seats of the vehicle. The passengers who are standing will not receive any conditioned or cool air. Further, as the duration of journey increases, the passengers may feel discomfort.
Efforts have been made to provide flow of conditioned air through a plurality of support bars arranged inside the vehicle. The plurality of support bars are connected to the air conditioning system on the roof at one end and to the floor of a vehicle with a joining members having a plurality of holes which direct the conditioned air inside the vehicle. However, this arrangement increases the number of components and cost of assembly. Moreover, the conditioned air can only be directed in a predefined

direction (or) a single direction proximate to the roof and floor of the vehicle and thereby does not provide required thermal comfort to the passengers. Some of the vehicles use air directing units such as fans equipped in the hand rails of the vehicle for the flow of conditioned or surrounding air which requires additional power. Also, these features requires complex mechanisms and increases overall power (or) fuel consumption of the vehicle.
The present disclosure is intended to overcome one or more above stated limitations.

In an embodiment, the plurality of openings (112) are arranged in multiple rows on the surface of the at least one flow regulator (110). The plurality of openings (112) are configured to receive the plurality of notches (116) therewithin to lock and restrict movement of the at least one flow regulator (110) over the at least one base member (106). The at least one flow regulator (110) is configured to slide on the at least one base member (106) along the axis (A-A). Additionally, the at least one flow regulator (110) is also rotatable around the at least one base member in a 360° angle. The at least one flow regulator (110) is operated linearly along the axis (A-A) to adjust a position of the plurality of openings (112) with respect to the at least one first vent (104) and the at least one second vent (108) to direct the air flow along the axis (A-A). The at least one flow regulator (110) can also be rotatably operated around the at least one base member (106) to direct the air flow around the axis (A-A). Thus, at least one flow regulator (110) can be selectively operated by a user to direct air flowing through the body (102) and the at least one base member (106) into various directions inside the vehicle (200) based on the requirement. In an embodiment, a stopper (113) may be provided at an exterior surface of the at least one base member (106). In an embodiment, the stopper (113) may engage with a bottom surface of the at least one flow regulator (110) to arrest further linear movement of the at least one flow regulator (110). In an embodiment, the body (102) and the at least one base member (106) may be defined with two of the first and second vents (104, 108) i.e. two first air vents (104) and two second air vents (108) respectively. Accordingly, the at least one flow regulator (110) may be defined with two columns of the plurality of openings (112), each column positioned adjacently.

Now referring to Figs. 3a-3e, various positions of the at least one flow regulator (110) with respect to the at least one base member (106) is illustrated. The two of the first and second vents (104, 108) (two first vents and two second vents) extend along the axis (A-A) are defined on the body (102), the at least one base member (106) respectively, along with two columns of the plurality of openings (112). However, this cannot be construed as a limitation and the number of vents and the rows of the plurality of openings (112) may be selected based on the requirement. The at least one flow regulator (110) is rotatably operated around the at least one base member (106) such that at least one vent of the first and second vents (104, 108) are aligned with the plurality of openings (112) to direct the air flow from a single vent (as shown in Fig. 3a). Accordingly, the at least one flow regulator (110) is further operated to close both the first and second vents (104, 108) to block the air flow within the at least one base member (106) (as shown in Fig. 3b). Further, two of the first and second vents (104, 108) are aligned with each column of the plurality of openings (112) by rotatably operating the at least one flow regulator (110) to direct air flow from all the first and second air vents (104, 108) (as shown in Fig, 3c). Additionally, the at least one flow regulator (110) is operated linearly to an extreme bottom position with respect to the at least one base member (106) to direct the air flow through a predefined portion of the first and second vents (104, 108) based on the requirement of the user (as shown in Fig. 3d). Similarly, the at least one flow regulator (110) can also be operated linearly to an extreme top position with respect to the at least one base member (106) for directing the air flow from the first and second air vents (104, 108) accordingly (as shown in Fig. 3e). In an embodiment, the at least one flow regulator (110) may be positioned between the extreme top position and the extreme bottom position regulating the air flow based on the requirement of the user.
Now referring to Fig. 4a, a system (300) for redirecting the air flow from an air conditioning unit (202) of the vehicle (200) with the air vent assembly (100) is disclosed. The air conditioning unit (202) may be mounted on a roof of the vehicle (200). A blower unit (not shown in Figs.) may be fluidly connected to the air conditioning unit (202) through at least one conduit (204). The blower unit may include a plurality of air directing means such as fans to direct a conditioned air from the air conditioning unit (202) to the at least one conduit (204). The at least one conduit (204) may extend along sides of the roof (203) extending in a lengthwise direction of the vehicle (200). A plurality of vents (205) may be defined on the roof (203) and are spaced apart from each other. The plurality of vents (205) may be configured to direct the conditioned air inside a passenger cabin (220) of the

vehicle (200). A plurality of rails (206) are connected to the at least one conduit (204) and extend along a length of the at least one conduit (204). The plurality of rails (206) are defined as a hollow structures to allow air flow therein. Each rail (206) of the plurality of rails (206) is disposed along the axis (A-A) and are configured to function as a support for a user. Each rail (206) of the plurality of rails (206) is defined with at least one first vent (104) on a portion of the at least one rail (206).
Referring to Fig. 4b, the system (300) further comprises a plurality of intermediate ducts (208) are disposed between the at least one conduit (204) and each of the plurality of rails (206). The plurality of intermediate ducts (208) may be hollow in structure and may be shaped in any configuration such as tapered, squared or cylindrical based on the requirement. Each of the plurality of intermediate ducts (208) are configured to fluidly connect the plurality of rails (206) with the at least one conduit (204) to allow flow of the conditioned air from the air conditioning unit (202) into the plurality of rails (206). The at least one air vent assembly (100) is mounted on each rail of the plurality of rails (206). The at least one air vent assembly (100) comprises of the at least one base member (106) fixedly mounted on the plurality of rails (206). The at least one base member (106) is defined with at least one second vent (108) aligned with the at least one first vent (104). The at least one second vent (108) is structured complementary to a shape of the at least one first vent (104) to secure the at least one base member (106) around the body (102). Further, the at least one base member (106) is defined with a plurality of notches (116) on the portion of the at least one base member (106) and extending along the axis (A-A). The at least one flow regulator (110) is movably mounted on the at least one base member (106). The at least one flow regulator (110) is defined with a plurality of openings (112) for controlling the air flow. The at least one flow regulator (110) is operated to selectively adjust a position of the plurality of openings (112) with respect to the at least one first vent (104) and the at least one second vent (108) to direct the air flow from the air conditioning unit (202) to various directions inside the vehicle (200). As an example, the user standing proximate to the plurality of rails (206) may operate the at least one flow regulator (110) linearly along a length of the plurality of rails (206) up to a portion of the at least one first vent (104). This causes the plurality of openings (112) of the at least one flow regulator (110) to orient with respect to the at least one first vent (104). This redirects the air flow towards the user in various directions (at different heights) along the axis (A-A). Similarly, if the user wants to stop the air flow, the at least one flow regulator (110) is operated or rotated around the plurality of rails (206) such that the at least one flow regulator (110) covers the

at least one first vent (104) thereby restricting the air flow. A plurality of vents (205) may be provided on each rail of the plurality of rails (206) such that each vent can be opened or closed by operating the at least one flow regulator (110) around the corresponding rail to direct the air flow around the axis (A-A).
In an embodiment, the plurality of rails (206) may also extend in a horizontal direction parallel to the roof (203) of the vehicle (200) to direct and control the air flow from the roof (203).
In an embodiment, the plurality of rails (206) may be in direct fluid communication with the at least one conduit (204) using any suitable fastening mechanism such as brackets, nuts, and bolts.
The air vent assembly (100) of the present disclosure is simple in construction and is retrofittable to any type of vents for redirecting the air flow in various directions based on the requirement.
The system (300) of the present disclosure enables the user to selectively adjust the direction of the air flow based on a height of the user and requirement of the user by simply operating the at least one flow regulator (110) of the air vent assembly (100). Also, the at least one flow regulator (110) can be rotatably operated to restrict of stop the air flow based on the requirement. Advantageously, this increases thermal comfort of the user through the journey during humid or pleasant weather conditions. Additionally, restricting the air flow also reduces load on the air conditioning unit (202) and thereby reduces power and fuel consumption of the vehicle (200).
The air vent assembly (100) of the present disclosure includes a lesser number of components. This reduces manufacturing and maintenance costs of the air vent assembly (100).
