TITLE: “A FLUSH GLASS ASSEMBLY FOR A VEHICLE”
NAME AND ADDRESS OF THE APPLICANT:
TATA MOTORS PASSENGER VEHICLES LIMITED of Floor 3, 4, Plot-18, Nanavati Mahalaya, Mudhana Shetty Marg, BSE, Fort, Mumbai, Mumbai City, Maharashtra, 400001 India
Nationality: Indian
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[001] Present disclosure relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to a door of a vehicle. Further, embodiments of the present disclosure disclose a flush glass assembly for the door of the vehicle.
BACKGROUND OF THE DISCLOSURE
[002] Generally, vehicles are equipped with window glasses, operatively disposed within doors of the vehicle. The door comprises an upper portion and a lower portion. The lower portion of the door includes a window glass actuator assembly, which moves the glass up and down upon actuation by a rider/driver of the vehicle. The upper portion of the door includes a frame/applique having a recess. A side portion of the glass contacts a side portion of the recess upon upward movement and a top portion of the glass contacts a top portion of the recess when the glass is raised to its maximum height. However, when the glass is in contact with the recess, a plane of the glass is away from a plane on an outer surface of the frame/applique. That is, a difference in width-wise height is formed between the glass and the outer surface of the frame/applique. In other words, the frame or applique projects outwardly from the glass surface.
[003] Due to such width-wise height difference or the applique’s outward projection, the vehicle experiences high air resistance while the vehicle is moving, which reduces aerodynamic profile and increases fuel consumption of the vehicle. Further, the air resistance creates turbulence, which in turn creates noise or whistle sound while the vehicle is moving, especially at higher speeds. Some efforts have been made to decrease the air resistance. One such modification in the applique assembly is to make the applique inwardly inclined to create a smooth air flow. However, such applique assembly is expensive to manufacture and less reliable in different environmental conditions. Further, such outward projection of the applique affects the aesthetics of the vehicle.
[004] Therefore, there is a need to maintain the applique and the glass in a same plane, to reduce air resistance. Further, the glass assembly needs to be manufacture cost-effectively and increase reliability in different environmental conditions. The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the aspect of the glass assembly of the vehicle.
[005] The drawbacks/difficulties/disadvantages/limitations of the conventional techniques explained in the background section are just for exemplary purpose and the disclosure would

never limit its scope only such limitations. A person skilled in the art would understand that this disclosure and below mentioned description may also solve other problems or overcome the other drawbacks/disadvantages of the conventional arts which are not explicitly captured above.

[0044] It is to be understood that a person of ordinary skill in the art may develop a flush glass assembly (200) of similar configuration without deviating from the scope of the present disclosure. Such modifications and variations may be made without departing from the scope of the present invention. Therefore, it is intended that the present disclosure covers such modifications and variations provided they come within the ambit of the appended claims and their equivalents.
EQUIVALENTS
[0045] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to

the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
[0046] In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
[0047] While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
[0048] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “an assembly (200)) having at least one of A, B, and C” would include but not be limited to the assembly that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C

together, etc.). In those instances, where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “an assembly (200) having at least one of A, B, or C” would include but not be limited to assembly that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.” While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
