• carrier 330 includes the following integrally molded or formed components: • a map pocket body 332, including a shelf structure 338, having a class A finished surface; • a speaker housing 350; • a side impact energy absorption structure 354, comprising a lattice of integrally molded ribs 356 (see Fig. 19A); • a motor and cable drum mounting receptacle 358; • a latch presenter rail 304 (see Fig. 19A); and • at least one flap 362 provided by "living" hinge 363, the illustrated embodiment having two such flaps 362 A and 362B.
• the secondary trim component 330 carries preferably all ofthe hardware components required for the typical vehicle door. These include: • a window regulator, generally designated by ref. no.
• brackets 374 A, 374B are bolted to the window regulator rails 364.
• Another bracket 378, comprising orthogonal extension 379, is also mounted to the carrier 330 using conventional fasteners.
• the lower trim panel 328B has a map pocket opening 329 which, when aligned with the upper edge ofthe shelf structure 338 on carrier 330, co-operatively defines a map pocket.
• the upper trim panel 328A is joined, and more preferably articulated to the lower trim panel 328B via hinges 388.
• the hinges 388 are preferably formed from plastic and fastened to the upper and lower trim panels at the secondary assembly plant. Each hinge 388 has fold lines at 389. This enables the upper trim panel to rotate about 180 degrees from a folded shipping position shown in Figs. 19A & 19B (see also Figs.
• the upper trim panel is co-located parallel to and suspended from the lower trim panel, to a vertical position shown in Fig. 20, where the upper trim panel is inline with but above the lower trim panel, and finally to an installed position, where the two trim panels are flush and interconnected as shown in Figs. 21 & 25.
• the hinges 388 fold out ofthe way enabling the upper trim panel 328A to overlap the carrier 330.
• the lower trim panel 328B is fixed to carrier 330 at a secondary assembly plant, prior to assembly ofthe door module to the structural door body.
• the preferred means for interconnecting these components includes a plurality (preferably four) of hooks 390 integrally formed on the rear ofthe lower trim panel 328B.
• hooks 390 which include integral side wedges 391, snap-fit into resiliently walled sleeves 392 (Fig. 19B) integrally formed on carrier 330, thus locking the two components together.
• the hardware module 386 forms a single transport unit shippable from the secondary assembly plant to the OEM plant.
• Figs. 22 A and 22B show the transport unit in opposing perspective views
• Fig. 23 is an end view of the transport unit.
• the door module 386 is mounted to the structural door body 312 as follows.
• the installer first slides the top ofthe window regulator rails 364 into the access holes 342A, 342B ofthe inner sheet metal layer 316 and inserts the loosely fitted bolts 365 ofthe window regulator rails 365 into the keyholes 306. Once this is accomplished the weight ofthe door module 386 is carried by the structural door body, as shown in Fig. 24, which is supported by the vehicle.
• the keyholes 306 allow the door module 386 to be manipulated so as to enable the installer to bolt the lower portion ofthe lower trim panel 328B to the structural door body 312.
• two bolts are passed through guide conduits 394 (Fig.
• the latch presenter 302 may be actuated as previously described in order to move the latch 376 into position.
• An outside handle (not shown) and key cylinder (not shown) may be connected to the latch.
• the wiring harness 372 may also be fished through various holes in the structural door body 312, which will vary depending on the application.
• the upper trim panel 328A is articulated to the vertical position, enabling the inside release handle on the panel to be attached to connecting rod 320.
• the upper panel 328A may then be moved to the installed position.
• the rear side ofthe upper trim panel 328A includes a series of integrally molded pyramid-like or frusto-pyramidical lugs 400 which seat in correspondingly shaped receptacles 402 integrally formed on the rear side ofthe lower trim panel 328B.
• the lower surface ofthe upper trim panel rests against a conespondingly shaped upper surface ofthe lower trim panel such that the trim appears to the observer as one continuous piece, as shown in Fig. 25.
• the upper trim panel may subsequently be easily moved into a position which is distanced from the carrier 330, so as to enable access to various hardware components for subsequent servicing.
• the integrally formed pull handle 404 (Fig. 25) is bolted (bolts not shown) to extension 379 of bracket 378 which, in turn, is fastened to platform 308 of inner sheet metal layer 316.
• the upper trim panel 328 may also be fastened to the inner sheet metal layer 316 or the carrier 330 at other locations, if desired.
• Figs. 26 A - 26C show a preferred embodiment of a hinge 410 for articulating the upper and lower trim panels 328A, 328B.
• the hinge is shown in these drawings in various positions of operation from a folded position in Fig. 26A to a fully extended position in Fig. 26C.
• the hinge 410 comprises a pintle member 412 and a gudgeon member 414 which provide pivotal motion about axis 416.
• the pintle member 412 has a fold line at 415 and includes a shoe 420 having axle 422.
• the shoe 420 is rotatingly interdigitated with a base member 424 that terminates in a plurality of hook-shaped projections 426 A in which axle 422 is seated, thus enabling the pintle member 412 to pivot about axis 428, which is orthogonal to axis 416.
• the base member 424 depends from, and is preferably integrally formed with, the upper trim panel 328A.
• the gudgeon member 414 includes a fold line at 430 and is rotatingly interdigitated with the hook-shaped head 432 of an extension member 434, thus enabling the gudgeon member 414 to pivot about axis 436.
• Fig. 26B the gudgeon member 414 includes a fold line at 430 and is rotatingly interdigitated with the hook-shaped head 432 of an extension member 434, thus enabling the gudgeon member 414 to pivot about axis 436.
• the extension member 434 slides in a sheath 438 preferably integrally formed with the lower trim panel 328B. This enables the trim panels to translate vertically with respect to one another.
• a releasable clip provided by a moveable cog 440 and a notch 442 cut into the extension member 434 maintains the extension member 434 in its sheath 438 when the hinge 410 is in its folded position.
• hinge components 412, 414 and 434 are readily inter-connectable and may be molded separately from the trim panels for subsequent installation thereon.
• the invention has been described in an illustrative manner. It is to be understood that the terminology that has been used is intended to be in the nature of words of description rather than of limitation. Many modifications and variations of the invention are possible in light ofthe above teachings. Therefore, the invention may be practiced other than as specifically described.
