[001] The present subject matter described herein, relates to a vehicle construction and more particularly, relates to relates to door trim assembly of a vehicle having high impact resistance.
BACKGROUND AND PRIOR ART:
[002] During side impact crash vehicle testing, a door trim of the vehicle gets deformed or crushed between door panel and crash dummy legs. As a result, instrument panels such as a bezel / armrest and door trim board of a door trim assembly of the vehicle gets popped out.
[003] Fig. 1 illustrates a state of the art vehicular door trim assembly 102. The vehicular door trim assembly 102 includes a bezel 105 and an armrest 104 mounted on a door trim board 106. In the illustrated arrangement, the bezel 104 is snap fitted on to the door trim board 106. The snap fitted arrangement is achieved through a plurality of snaps. However, the provision of snaps does not provide effective constraining of the bezel 104 on the door trim board 106, due to which the bezel 104 pops out during a side impact crash test of the vehicle.
[004] Korean Patent publication KR100526808B1 provides a method for assembling an armrest by inserting an armrest on an upper surface of a main panel by screwing a main panel into a door trim by fastening means such as a retainer, Thus, it is easy to arrange the armrest on the main panel coupled to the door trim when the vehicle is assembled, thereby improving the assembling ability. In addition, even when a side collision occurs while the vehicle is running, the impact energy is absorbed by the armrest, thereby suppressing the injuries of the occupant on the vehicle cabin from being injured.
[005] However, the components, assembly, shape, and location of the parts mentioned in the prior art is not similar to the present disclosure.

OBJECTS OF THE INVENTION:
[006] The principal objective of the present invention is to provide an impact resistant vehicular door trim assembly incurring less deformation during side impact crash test.
[007] Another object of the present subject matter is to provide a simple, cost effective, and efficiently designed vehicular door trim assembly that is distinct from all conventional designs.
SUMMARY OF THE INVENTION:
[008] The present invention relates to an impact resistant vehicular door trim assembly including a door trim board having a plurality of weld bosses; a bezel configured to be positively mounted on the door trim board through a plurality of snaps, the plurality of snaps being disposed across the bezel, the plurality of snaps defining a flanged opening; an impact absorbing pad configured to be secured to the door trim board; and a bracket configured to secure the bezel to the door trim board.

[0018] Fig. 2 illustrates an impact resistant vehicular door trim assembly 200, hereinafter referred to as vehicular door trim assembly 200, in accordance with an embodiment of the present disclosure. In an embodiment, the vehicular door trim assembly 200 includes a door trim board 202, a bezel 206, an impact absorbing pad 212, and a bracket 216 having a substantial Z shaped profile.
[0019] Fig. 3 illustrates an exploded view of the vehicular door trim assembly 200 of Fig. 2 in accordance with an embodiment of the present disclosure. As shown, the door trim board 202 of the vehicular door trim assembly 200 includes a plurality of weld bosses 204 configured for fusion welding. In an example, the door trim board 202 includes six (6) weld bosses 204. The bezel 206 of the vehicular door trim assembly 200 is configured to be positively mounted on the door trim board 202. In an embodiment, the positive mounting of the bezel 206 on the door trim board 202 is achieved through a plurality of snaps 208, the plurality of snaps 208 being disposed across the bezel 206. In an example the plurality of snaps 208 defines a flanged opening 210 over an extended length of the plurality of snaps 208.

[0020] The vehicular door trim assembly 200 further includes the impact absorbing pad 212 provided between the door trim board 202 and the bezel 206, such that a positioning of the impact absorbing pad 212 is adjacent to thigh of a crash dummy. In an example, the impact absorbing pad 212 is configured to be 5 secured to the door trim board 202. The impact absorbing pad 212 defines a plurality of extensions 214 corresponding to the plurality of weld bosses 204, wherein the plurality of extensions 214 are configured to be fusion welded to the plurality of weld bosses 204 for securing the impact absorbing pad 212 to the door trim board 202. In an example, the impact absorbing pad 212 is an EPP pad, and 10 is configured to absorb a side impact on a door of a vehicle having the vehicular door trim assembly 200 during a side impact crash test. The impact absorbing pad 212 provides high impact resistance to the vehicular door trim assembly 200, and reduces the deformation caused to the vehicular door trim assembly 200 from the crash dummy thigh.
15 [0021] The vehicular door trim assembly 200 further includes the Z shaped bracket 216. In an embodiment, the Z shaped bracket 216 is configured to secure the bezel 206 to the door trim board 202. In an example, the Z shaped bracket 216 define a first vertical part 218 meant to be coupled to the bezel 206 through the flanged opening 210, and a second vertical part 220 meant to be coupled to the
20 door trim board 202 through the plurality of weld bosses 204, the first vertical part 218 and the second vertical part 220 separated by an intermediate part 217. In an example, the Z shaped bracket 216 is made of plastic. Alternatively, the Z shaped bracket 216 may be metallic or made up of resin.
[0022] Further, the first vertical part 218 includes a first orifice 219 corresponding 25 to the flanged opening 210 of the plurality of snaps 208, such that the first vertical part 218 of the Z shaped bracket 216 is secured to one of the plurality of snaps 208 through a fastener 221 (See Fig. 2). In an example, the fastener 221 may include a high speed nut and bolt arrangement. Further, the second vertical part 220 includes a plurality of second orifices 223 corresponding to the plurality of
6

weld bosses 204, such that the second vertical part 220 of the Z shaped bracket 216 is fusion welded to the door trim board 202.
[0023] In operation, during a crash test, the vehicular door trim assembly 200 deforms less due to presence of the impact absorbing pad 212. Further, due to positive mounting of the bezel 206 on the door trim board 202 through the plurality of snaps 208 and the Z shaped bracket 216, the bezel 206 does not get popped out from the door trim board 202.
[0024] Although embodiments for the present subject matter have been described in language specific to structural features, it is to be understood that the present subject matter is not necessarily limited to the specific features described. Rather, the specific features and methods are disclosed as embodiments for the present subject matter. Numerous modifications and adaptations of the system/component of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the scope of the present subject matter.
