, Description:A VEHICLE DOOR WITH A BELTLINE CAP FITMENT STRUCTURE
TECHNICAL FIELD
[0001] The present disclosure relates to an inner structure of a vehicle door. More particularly, the present disclosure relates to a vehicle door with a beltline fitment structure that is capable of securing assembly and reducing noise level.
BACKGROUND
[0002] A vehicle door is normally designed so that a door frame is vertically arranged on an upper part of a door panel to form a window area, and a window (door glass) disposed inside the door panel is moved upward and downward in the window area.
[0003] The door panel consists of an outer panel that forms an outer side of the vehicle door, and an inner panel that forms an inner side of the vehicle door, and the window is disposed between the outer panel and the inner panel.
[0004] A beltline cap is fitted to an upper edge of a door trim fixed to the door inner panel. On external side, the beltline cap comes in sliding contact with a weather strip of the window. On internal side, an upper end of the beltline cap is fitted with a door trim with snaps, and a lower end of the beltline cap is fitted with the door trim through bosses.
[0005] The beltline cap maintains a desired gap with the door trim in beltline area of a vehicle. This is very important in terms of aesthetics as beltline area is visible to the customer from vehicle outside.

[0006] However, sometimes, during assembly of the door trim over the weather strip, the snaps formed on the door trim for holding the upper end of the beltline cap rotate. Because of this, there is a chance of undesired gap formation between the door trim and the beltline cap which becomes visible from the vehicle outside. Moreover, no gap control mechanism is proposed in the existing design of the door trim and the beltline cap.
[0007] In order to overcome the above mentioned problem, one of the prior arts has proposed a gap control mechanism between the door trim and the beltline cap by maintaining the full surface contact between the door trim and the beltline cap. But, due to the full surface contact, noise is generated when there is any vibration in the vehicle door.
[0008] It is, therefore, desirable to provide a vehicle door with an improved beltline fitment structure which overcomes the above mentioned problems, to maintain a stable connection between the beltline cap and the door trim while reducing the noise level.

[0030] The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.
[0031] As used in the description herein and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
[0032] In a vehicle door with a conventional beltline fitment structure 100 as shown in FIGS. 1A and 1B, a beltline cap 102 is fixed with a door trim 104. For instance, an upper end 102A of the beltline cap 102 is fitted with snaps 106 formed on the door trim 104, while a lower end 102B of the beltline cap 102 is fitted with the bosses 108 formed on the door trim 104.
[0033] As mentioned above, sometimes, during assembly of the door trim 104 over the weather strip (not shown in figures), the snaps 106 may rotate, which results into undesired gap formation between the door trim 104 and the beltline cap 102. This undesired gap also becomes visible from vehicle outside, and is aesthetically not appreciable. Also, such formation of undesired gap defies the intended objective of the beltline cap 102.
[0034] The present disclosure aims to solve a technical problem of the existing beltline cap fitment structure provided in the vehicle door. The present disclosure clearly explains the configuration of the beltline cap fitment structure provided in the vehicle door in the below-mentioned explanation of figures.
[0035] To address the issues of the existing beltline fitment structure 100, the subject matter disclosed herein proposes a vehicle door having a door trim 200 as shown in FIGS. 2A-2B. The door trim 200 includes T-shaped hooks 202 for fixing upper end of a beltline cap (not shown in FIGS. 2A-2B) and includes bosses 204 for fixing lower end of the beltline cap. Further, in an aspect, as can be seen from FIG. 2C, each of the T-shaped hooks 202 has an extended lower horizontal portion 202A so as to provide rigid support in addition to the fitment of the beltline cap, while maintaining a zero contact with beltline cap.
[0036] FIG. 3A illustrates a beltline cap 300 in accordance with an embodiment of the present disclosure. The beltline cap 300 includes an upper end and a lower end. On the upper end, a number of T-shaped slots 302 are formed to receive the corresponding T-shaped hooks 202 for fixture with the door trim 200. On the lower end, a number of holes 304 are formed to receive the corresponding bosses 204.
[0037] FIG. 3B illustrates an enlarged view of one of the T-shaped slots 302 in accordance with an embodiment of the present disclosure.
[0038] FIG. 3A further illustrates the beltline cap 300 having the upper end with a downward extending protrusion 306, which is fitted with an weather strip mounted on an inner panel of the vehicle door.
[0039] FIG. 4A illustrates an assembled state of the door trim 200 and the beltline cap 300, in accordance with an embodiment of the present disclosure. As can be seen from FIG. 4A, in the assembled state, one of the T-shaped hooks 202 is fitted into the corresponding one of the T-shaped slots 302. In the assembled state, the extended lower horizontal portion 202A of said T-shaped hook 202 supports the beltline cap 300 while maintaining a zero contact with a portion of the T-shaped slot 302 of the beltline cap 300. Further, the beltline cap 300 is in zero contact with the door trim 200 through a raised profile 308 formed on the beltline cap 300 providing minimum surface contact between the beltline cap 300 and the door trim 200. Due to the minimum surface contact, noise level generated between the door trim 200 and the beltline cap 300 is reduced.
[0040] FIG. 4B illustrates a cross-sectional view of the assembled door trim 200, the beltline cap 300, and a weather strip 402 mounted on an inner panel 404 of a vehicle door 400. As can be seen from FIG. 4B, the beltline cap 300 extends from a lower end to an upper end in multiple steps 406 in accordance with an embodiment of the present disclosure. Such multiple step configuration of the beltline cap 300 enhances rigidity of the beltline cap 300 while providing limited surface contact between the beltline cap 300 and the door trim 200 as there is a constant gap between the door trim and the beltline cap 300.
[0041] In an aspect, the beltline cap 300 is having a length equal to the upper end of the door trim 200.
[0042] The various technical advantages associated with the beltline cap fitment structure proposed herein are:
• Better control of desired gap between the beltline cap and the door trim;
• Enhance the aesthetics in beltline region of the vehicle door;
• Reduction in noise level; and
• Improvement in rigidity of the beltline cap due to multiple step configuration of the beltline cap.
[0043] Further, it will be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of the invention and are included within its scope.
[0044] Furthermore, all examples recited herein are principally intended expressly to be only for pedagogical purposes to aid the reader in understanding the principles of the invention and the concepts contributed by the inventor(s) to furthering the art and are to be construed as being without limitation to such specifically recited examples and conditions. Also, the various embodiments described herein are not necessarily mutually exclusive, as some embodiments can be combined with one or more other embodiments to form new embodiments.
