PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD OF THE INVENTION
Present invention, in general, relates to a vehicle with a slidable cover system. Particularly, but not exclusively, the present invention relates to the vehicle with the slidable cover system for a rear storage compartment.
BACKGROUND OF THE INVENTION
Conventionally, a vehicle rear storage compartment is used to store luggage and other items such as car jacks, spare parts, tools and the like. A typical vehicle rear storage compartment comprises a luggage floorboard region, and a luggage cover detachably fixed immediate to at least one passenger sitting row. Generally, the luggage cover is positioned above the luggage floorboard region, thereby providing enough space there between for storing, loading and unloading the luggage and other items.
During a vehicle running condition, while the stored items on the luggage cover can be accessed by the vehicle user from a passenger seat assembly, however, in order to access storage items from the luggage floorboard region, the vehicle user needs to, every time, stop the vehicle, open and close the tailgate for loading or unloading the same.
In a known art, during the vehicle running condition, the vehicle user is able to fold/unfold the passenger seat assembly for accessing the luggage floorboard region from inside cabin, which in general causes discomfort to the vehicle user and other occupants. Moreover, for facilitating folding of the seat assembly for accessing the luggage floorboard area from inside the cabin, a predefined gap is kept between the seat assembly and the luggage cover position, which however does not provide aesthetically appealing appearance of the storage compartment.

Present invention is directed to overcome one or more limitations stated above or any other limitations associated with the known arts.

Figure 2 to Figure 5 illustrates a right- side view of at least a portion of the rear storage compartment (R’) of the vehicle (100) of Figure.1, in accordance with an embodiment of the present invention. In an illustrated embodiment, a slidable cover system (200) for the rear storage compartment (R’) is disposed rear of the front compartment (F’) and extends along a vehicle transverse axis (ZZ’). The slidable cover system (200) includes a predefined slot (604) formed in at least an inner surface (606) (shown in Figures 6 to 8) of at least one pair of left and right panel (102R), a spring- loaded mechanism (600) (shown in Figures 6 to 8) disposed in at least an inner surface (607) (shown in Figures 6 to 8) of at least one pair of left and right reinforcement member (C) in a plane with the predefined slot (604), a first cover (202) hingedly attached to the at least one pair of left and right panel; (103L), (103R) and a second cover (201) configured to slide over the first cover (202) from an extended cover condition (E) to a retracted cover condition (E’) and vice versa, through the spring- loaded mechanism (600) along the prefined slot (604). at least one handle structure (207) are provided on the second cover (201), the at least one handle structure (207) are adapted for manually sliding the second cover (201) from the extended cover condition to a retracted cover condition (E’) for accessing luggage space (300) from the at least one pair of seat assemblies (203).
Figure 2, as per an embodiment, illustrates the extended cover condition (E) for the slidable cover system (200). During the extended cover condition, at least one seat assembly (209) of the plularity of the seat assemblies (203) is in a non-reclining position. Also, in said extended cover condition (E) the rear storage compartment is covered completely with the second cover (201) being positioned immediate rear and along a length of the plurality of the seat assemblies (203), thereby creating no

gap between the seat assembly (209) and the slidable cover system (200) when the vehicle user does not require to access or recline the seat assembly (209).
Further in Figure 2, the first cover (202) (202) is hingedly connected to the at least one pair of left and right panels (102L), (102R) corresponding to the pair of left and right quarter panels through a hinge-pin (208).

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., "a system having at least one of A, B, and C" would include but not be limited to systems 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., "a system having at least one of A, B, or C" would include but not be limited to systems 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."
In addition, where features or aspects of the invention are described in terms of Markush groups, those skilled in the art will recognize that the invention is also thereby described in terms of any individual member or subgroup of members of the Markush group.
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.
