Best Mode For CarrYinq Out The In~ention With reference to the drawings, the preferred embodiments of the present invention will be described.
Figures 1 and 2 show a door assembly 10 according to the present invention for a motor vehicle. The door assembly 10 comprises a base door trim panel or substrate 12, a belt line reinforcement 14, a lock and catch assembly 16, and a window lift assembly 18. The base door panel 12 is preferably a unitary, injection molded piece comprising an olephenic thermoplastic such as polypropylene which is relatively rigid after curing, an engineered acrylonitrile-butadiene-styrene (ABS), or a glass-reinforced composite.
The base door panel 12 has a first or front side and a second or back side 22. The front side is , CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594 -adapted to face into a passenger compartment of the motor vehicle, and may include as attachments or integral parts thereof an arm rest, a bolster, a map pocket 24, a cloth applique or other trim finish, any lights or reflectors, power switch controls, a speaker compartment 26 and a speaker grill, and an aesthetic carpet.
The belt line reinforcement 14 provides increased structural rigidity to the door panel 12, and in particular provides a structure against which a side window glass 28 can be loaded, a function normally provided by the same structure which is conventionally part of the door inner. The belt line reinforcement 14 may either be formed integrally with the door panel 12, or separately formed as a metal stamping or casting for attachment to the back side 22 of the door panel. In the latter case, the belt line reinforcement preferably comprises steel, magnesium, an engineered plastic or any o~her material with sufficient structural properties.
Figure 3 shows another alternative embodiment in which the belt line reinforcement 14' is integrally formed with or welded to a window frame or header 29, while ~igure 4 shows the belt line reinforcement and window frame subassembly attached to the door panel 12.
The lock and catch assembly 16 includes a door inner handle 30, a lock assembly 32 and a catch assembly 33. The door inner handle 30 slides into place within a door handle housing 34 formed in the door panel 12 or separately provided and attached to the door panel. A
metal bracket attaches an exterior handle assembly 39 to the door panel 12. The catch assembly 33 is secured to the door panel, preferably with three fasteners such as screws 43. Lock release rod 41 extends between the keyhole of the lock assembly 32 and the catch assembly 33, while lock release rod 45 extends between the lock CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09~94 assembly and the exterior handle assembly 39. A cable 38 connects the door inner handle 30 to the lock assembly 32, as ls well known. The lock and catch assembly 16 uniquely combines anti-theft, lock mounting and glass edge guides functions into one unit.
Figures 14-16 show an alternative embodiment lO0 of the lock and exterior handle assembly. The assembly 100 includes an alternative embodiment 101 of the metal mounting bracket which attaches the assembly to the belt line reinforcement. Unlike its counterpart shown in Figures 1 and 2, the bracket 101 does not incluae glass run guides as described below. A cover or carrier 102 has a flange 103 with holes 104 that engage, preferably by snap fit, projections 105 on the bracket 101. Arms 106 and 107 respectively extend through vertical slots 108 and 109 in the carrier 102, through an adhesive-backed seal llO provided on the carrier, and out through slots 111 and 112 in a sheet metal door outer 113 for snap fit attachment to exterior handle 114. To secure the arms 106 and 107, pin 127 extends through projections 128 on the rear side of the carrier, through a hole in the arm 106, through spring 129 and a holes in the arm 107, and mates with a pin 130.
Lock release rod 41 is attached at its upper end to hole 115 in a lock cam 116, and at its lower end is attached to a projection 117 on door latch 118.
Similarly, lock release rod 45 is attached at its upper end to a hole 119 in arm 106, and is attached at its lower end to projection 121 on the door latch 118.
Fasteners 122 extend through respective slots 123 and 124 in the carrier 102 and seal 110 to secure the unit 100 as a subassembly, and snap into holes or slots 125 in doghouse brackets 126 attached to the outer panel 113 to secure the unit 100 to the outer panel. A~ter the trim panel 12 is attached to the outer panel, the handle CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594-114 is snapped onto arms 106 and 107, and a lock cylinder 127 inserted through corresponding holes in the door outer 113 and the carrier 102, and into engagement with the lock cam 116.
Referring again to Figures 1 and 2, the window lift assembly 18 includes a motor 40, a generally horizontally oriented regulator 42, and a generally vertically oriented guide member 44 for the window regulator. The motor 40 is attached to the door panel 12, preferably by snap fit, and the window glass 28 is secured into a groove in the regulator 42 by one or more fasteners 46. The window glass 28 is supported by glass run channels or edge guides 48 and 50, each of which includes a weather seal. The guides 48 and 50 are either integrally molded with the door panel 12, or formed as separate metal or plastic pieces and fastened at their lower ends to the door panel 12 or to an extension of the belt line reinforcement, and at their upper ends to the belt line reinforcement 14. It should be understood, of course, that a motor is not required for manual operation of the window glass.
The regulator 42 thereafter moves the window glass up or down when the motor 40 alternately draws cables 52 and 54. A belt line glass seal or sweep 56 attached to a flange on the belt line reinforcement 14 generally adjacent the top of the door panel 12 provides an additional weather seal. A water management sheet 68, preferably formed of plastic such as polyethylene, polyurethane or a closed cell foam, inhibits the introduction of water, noise and dust from the interior of the door into the passenger compar~ment.
Figure 18 shows an embodiment 500 of the door assembly including a scissors type or arm-and-sector window lift assembly. A window lift motor 502 has a rig~t angle drive which drives a toothed member 504 ., .. .~ . ~ . ...... .. .. . . . .
CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594 --either clockwise or counterclockwise about a pivot point 506. The toothed member 504 is fastened to or integral with an extension 508, which at its distal end includes a roller 510. The roller 510 rides in a track in a regulator 512 fastened to the bottom of the window. A
similar roller 514 also rides in the regulator track, and is connected to a cross member 516 pivotally connected at 518 to the extension 508. The opposite end of the cross member 516 includes a roller 520 that rides in a stationary horizontal track 522. The track 522 may be fixed to the door panel, formed as an extension of the assembly that includes the motor 502, or fastened at its opposite ends to the belt line reinforcement. As the motor 502 drives the toothed member 504 clockwise, the regulator 512 ascends and the window 28 is raised.
As the toothed member 504 turns counterclockwise, the regulator descends and the window is lowered.
Figure 19 shows an embodiment 600 of the door assembly including a dual regulator window lift assembly. Two spaced apart regulators 602 and 604 ride on guide members 606 and 608, and engage the bottom of the window 28. A window lift motor 610 draws a continuous cable 614 in opposite directions to respectively move the regulators 602 and 604 and the window up or down along the guides 606 and 608.
Figure 20 shows an embodiment 700 of the door assembly in which the catch assembly 733 is allowed to float on the door panel 712. Prior to assembly with the outer panel, the catch assembly 733 is suspended by the lock release rods and other attachmen~s which allow the catch assembly a small amount of movement relative to the door panel 712. This feature allows the door inner and outer panels to be brought together without the need for precisely locating the catch assembly 733 relative to the outer panel. For final assembly, fasteners CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594--extending through holes 750 secure the belt line reinforcement 714 to the outer panel, and fasteners extending through holes 752 secure the catch assembly 733. The door panel 712 may also be secured to the door outer by fasteners, ultimately concealed by appliques 754, engaging receivers 756. A door grab 758 is also provided which is attached for strength to the belt line reinforcement 714.
Figures 21 and 22 show an embodiment 800 of the door assembly in which the door panel 812 is loaded to the outer panel by first locating guides 806 and 808 above corresponding mounting receivers in the outer panel, and then pivoting door panel 812 about its lower end as indicated by the arrow in Figure 22. The door panel 812 is thereafter lowered into place, by gravity or otherwise, such that a male electrical connector 872 described more fully below vertically engages a female electrical connector 874 as indicated by the arrows in Figures 21 and 22. The door panel 812 is thereafter secured to the outer panel by any method described herein.
In any of the embodiments of the present invention, a secondary seal can be provided around the perimeter of the engagement between the door inner and outer panels. The seal can be formed with a seal gun, or a separately applied peel and stick seal can be used.
Any form of the seal has the additional advantage of isolating the door inner to minimize the occurrence of squeak and rattle.
Referring again to Figure 1, a wiring harness 58 carries electrical current to all necessary components, and includes plug-in connectors such as speaker connector 60, regulator connector 62, power lock connector 64, and connectors for any power mirror connected to flange 65. The harness 58 ls attached to . , ~ ......... .
CA 022~673~ 1998-ll-30 W097/45283 PCT~S97/09594--the door panel 12 as necessary, preferably by positioning some or all of its length within channels or hooks molded into the door panel or the belt line reinforcement. Door side impact components, such as a foam block 70 or an air bag, may also be secured to the door panel 12.
A male section 72 of a self-aligning and/or self-docking electrical connector may be mounted proximate the hinge side of the door panel 12 shown in Figure 1. Figure 5 shows the electrical connector comprised of the male section 72 mounted to the door panel 12 and a female section 140 mounted on a door outer panel 200. The male section 72 consists preferably of four spring-loaded contacts 142 having semi-spherical surfaces 143 located in a mounting plate 144 within a box 120. The female section 140 consists of the same number of inverted semi-spherical or crown shaped receptors 146. The receptors 146 can be made of beryllium copper alloy (BeCo) or other suitable material, and can be connected to a traditional electrical connector in the body of the motor vehicle.
During assembly, the installer simply translates the box 120 relative to the adjacent female section 140 until correctly positioned. At this point, the contacts 142 automatically fall into the receptors 146, thereby facilitating an electrical connection. A locator pin (not shown) can be provided in addition to the spherical contacts 142. The connector 72 shown in Figure 1 can be mated with an electrical extension 76 shown in Figure 4 as part of the door panel 12, or alternatively the extension 76 can be separately provided as part of a sheet metal door exterior for connection to the connector 72 as shown in Figure 6. Further details of the connector 72 can be found in U.S. patent application filed August 28, 1996 and titled Self-Aligning and Self-CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594 Docking Electrical Connector, assigned to the assignee of the present invention and hereby incorporated by reference. Instead of the electrical connector section 72, the harness 58 may be provided with a conventional pass through 78 including a seal 66 integral with the harness at the door-to-body pass through point to inhibit water seepage into the door cavity, as shown in Figure 2.
The assembled door assembly 10 is adapted for joining with the sheet metal door exterior by bringing it adjacent the door exterior, and locating the electrical connector section 72 with its mating section if so provided of the door exterior. The door assembly 10 is attached to the door exterior at the belt line with either a plurality of bolts or screws, or by separate plastic fasteners or fasteners integrally molded with the door panel, and finally securing the door assembly 10 around its periphery. One significant advantage of the door panel of the present invention, however, is that its electrical components can be tested prior to assembly with the door outer panel.
The assembly sequence for the structural door of the present invention is as follows. First, the base door panel 12 is placed on a conveyor for off line assembly, and the water management provisions are added.
The belt line reinforcement is then attached to the base door panel, if not already formed as an integral part thereof. The door side impact components are then attached, after which the door inner handle is slid into place and secured and the lock subassembly is secured with the three screws. The electrical wire harness is then positioned, and the connectors are attached to positions near their respective components. The lock electrical attachment is then completed. The door regulator is then positioned and snapped, screwed or CA 022~673~ 1998-ll-30 W097/45283 PCT~S97/09594-bolted into place, the cables routed and the guide secured and the electrical connection made. Next, the left and right door glass edge guides are positioned and secured at the top and bottom, and the door glass seals are attached into the guides.
The speaker is then snapped or screwed into the door panel, and the grille cover snapped over the speaker and the electrical connection completed. The exterior handle adapter subassembly/theft prevention bracket is then attached and the rods for lock release are attached to the lock. The belt line glass seal is next pushed onto the belt line flange. The door glass is then located in the glass edge seals and located to the regulator guide and secured with the fasteners.
Finally, the mirror is installed using three studs with the mirror and attaching three nuts and a foam seal. A
power or mechanical mirror cable is routed and connected, if necessary.
An alternative assembly sequence is to first snap fit the interior handle bezel 30 onto the base door panel 12, and then fasten the map pocket on the base door panel. Next, the base door panel is rotated 180 degrees so that the back side 22 faces upwardly, and the map pocket is slued, screwed or ultrasonically or vibrationally welded in place. The base door panel is then unloaded from the conveyor and placed in a vertical orientation, and the belt line reinforcement is added.
Contemporaneously or immediately thereafter, the speaker, speaker grille, foam and wire harness are added. After the wire harness is routed, the interior handle lock cable 38 is added. The electrical connections are then made, and the glass run channels added. The window regulator is then positioned and electrically connected. A pull cup is snapped into the door panel arm rest, and any necessary electrical CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594-connections such as for power windows are made.
Finally, the window glass is added and connected to the regulator.
Figure 6 shows one alternative ~or attaching the door panel 12 to the door outer panel 200. As shown by the arrow, a latch housing 202 of the door panel 12 is ~irst inserted through an opening 204 in the door outer panel 200, and the female electrical connector 140 is aligned with the male connector on the door panel 12.
To partially secure the door panel 12 to the outer panel 200, a series of bolts or other fasteners are then inserted through horizontally-aligned holes 210 and 212 in the door panel 12 and outer panel 200, respectively.
A bottom portion 213 of the window regulator guide extending generally below the periphery of the door panel 12 may be seated in an indentation 215 formed in the door outer panel to assist locating the panels relative to each other.
Figure 7 shows another alternative for mounting the door panel 12 to an outer panel 200~. As shown by the arrow, the door panel 12 is inserted straight into the door outer panel 200' such that a latch flange 214 fits into a notch 204' formed in the outer panel and the electrical extension 76 aligns with notch 206. Diagonally-aligned mounting holes 210~ and 212' are provided in the panels 12 and 200', respectively, and thereafter the panels are secured together as described above. The window regulator guide portion 213 may again be seated in the indentation 215 to assist this loading.
Figure 17 shows another alternative build in which a door panel 12' is located by the portion 213 cooperating with indentation 215 in outer panel 200''.
The door panel 12' is then secured with fasteners including screws 250 inserted generally normally to the ,-- ... . . .
CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594-plane defined by the door panel 12' and screws 252 inserted generally parallel to the plane of the door panel through flange 254 and into a portion 256 of the door outer panel.
The base door panel 12 is either injection molded, compression molded or formed of a glass-reinforced urethane (GRU). Figures 8, 9 and 10 show the back side of alternate door panels 12 formed respectively by each of these methods. In Figure 9, a combination speaker reinforcement and map pocket 300 and a latch reinforcement 302, both preferably injection molded, are provided. In the GRU door trim panel of Figure lO, the belt line reinforcement 14 is molded in so that only a flange 304 is exposed.
Figure 11 shows a watershield 400 for use with the door assembly of the present invention. The watershield 400 is preferably formed from a polyethylene, polyurethane or a closed cell foam, and is sealed, as least in part by means such as an adhesive bead 402, over certain of the door panel components as shown in Figures 12 and 13.
It should be understood that while the forms of the invention shown and described above constitute preferred embodiments of the invention, they are not intended to illustrate all possible forms thereof. It should also be understood that the words used are words of description rather than limitation, and various changes may be made without departing from the spirit and scope of the invention disclosed.

A cable 38 connects the door inner handle 30 to the lock assembly 32, as ls well known. The lock and catch assembly 16 uniquely combines anti-theft, lock mounting and glass edge guides functions into one unit.
Figures 14-16 show an alternative embodiment lO0 of the lock and exterior handle assembly. The assembly 100 includes an alternative embodiment 101 of the metal mounting bracket which attaches the assembly to the belt line reinforcement. Unlike its counterpart shown in Figures 1 and 2, the bracket 101 does not incluae glass run guides as described below. A cover or carrier 102 has a flange 103 with holes 104 that engage, preferably by snap fit, projections 105 on the bracket 101. Arms 106 and 107 respectively extend through vertical slots 108 and 109 in the carrier 102, through an adhesive-backed seal llO provided on the carrier, and out through slots 111 and 112 in a sheet metal door outer 113 for snap fit attachment to exterior handle 114. To secure the arms 106 and 107, pin 127 extends through projections 128 on the rear side of the carrier, through a hole in the arm 106, through spring 129 and a holes in the arm 107, and mates with a pin 130.
Lock release rod 41 is attached at its upper end to hole 115 in a lock cam 116, and at its lower end is attached to a projection 117 on door latch 118.

Fasteners 122 extend through respective slots 123 and 124 in the carrier 102 and seal 110 to secure the unit 100 as a subassembly, and snap into holes or slots 125 in doghouse brackets 126 attached to the outer panel 113 to secure the unit 100 to the outer panel. A~ter the trim panel 12 is attached to the outer panel, the handle CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594-114 is snapped onto arms 106 and 107, and a lock cylinder 127 inserted through corresponding holes in the door outer 113 and the carrier 102, and into engagement with the lock cam 116.
Referring again to Figures 1 and 2, the window lift assembly 18 includes a motor 40, a generally horizontally oriented regulator 42, and a generally vertically oriented guide member 44 for the window regulator. The motor 40 is attached to the door panel 12, preferably by snap fit, and the window glass 28 is secured into a groove in the regulator 42 by one or more fasteners 46. The window glass 28 is supported by glass run channels or edge guides 48 and 50, each of which includes a weather seal. The guides 48 and 50 are either integrally molded with the door panel 12, or formed as separate metal or plastic pieces and fastened at their lower ends to the door panel 12 or to an extension of the belt line reinforcement, and at their upper ends to the belt line reinforcement 14. It should be understood, of course, that a motor is not required for manual operation of the window glass.
The regulator 42 thereafter moves the window glass up or down when the motor 40 alternately draws cables 52 and 54. A belt line glass seal or sweep 56 attached to a flange on the belt line reinforcement 14 generally adjacent the top of the door panel 12 provides an additional weather seal. A water management sheet 68, preferably formed of plastic such as polyethylene, polyurethane or a closed cell foam, inhibits the introduction of water, noise and dust from the interior of the door into the passenger compar~ment.
Figure 18 shows an embodiment 500 of the door assembly including a scissors type or arm-and-sector window lift assembly. A window lift motor 502 has a rig~t angle drive which drives a toothed member 504 ., .. .~ . ~ . ...... .. .. . . . .
CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594 --either clockwise or counterclockwise about a pivot point 506. The toothed member 504 is fastened to or integral with an extension 508, which at its distal end includes a roller 510. The roller 510 rides in a track in a regulator 512 fastened to the bottom of the window. A

The opposite end of the cross member 516 includes a roller 520 that rides in a stationary horizontal track 522. The track 522 may be fixed to the door panel, formed as an extension of the assembly that includes the motor 502, or fastened at its opposite ends to the belt line reinforcement. As the motor 502 drives the toothed member 504 clockwise, the regulator 512 ascends and the window 28 is raised.
As the toothed member 504 turns counterclockwise, the regulator descends and the window is lowered.
Figure 19 shows an embodiment 600 of the door assembly including a dual regulator window lift assembly. Two spaced apart regulators 602 and 604 ride on guide members 606 and 608, and engage the bottom of the window 28. A window lift motor 610 draws a continuous cable 614 in opposite directions to respectively move the regulators 602 and 604 and the window up or down along the guides 606 and 608.
Figure 20 shows an embodiment 700 of the door assembly in which the catch assembly 733 is allowed to float on the door panel 712. Prior to assembly with the outer panel, the catch assembly 733 is suspended by the lock release rods and other attachmen~s which allow the catch assembly a small amount of movement relative to the door panel 712. This feature allows the door inner and outer panels to be brought together without the need for precisely locating the catch assembly 733 relative to the outer panel. For final assembly, fasteners CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594--extending through holes 750 secure the belt line reinforcement 714 to the outer panel, and fasteners extending through holes 752 secure the catch assembly 733. The door panel 712 may also be secured to the door outer by fasteners, ultimately concealed by appliques 754, engaging receivers 756. A door grab 758 is also provided which is attached for strength to the belt line reinforcement 714.
Figures 21 and 22 show an embodiment 800 of the door assembly in which the door panel 812 is loaded to the outer panel by first locating guides 806 and 808 above corresponding mounting receivers in the outer panel, and then pivoting door panel 812 about its lower end as indicated by the arrow in Figure 22. The door panel 812 is thereafter lowered into place, by gravity or otherwise, such that a male electrical connector 872 described more fully below vertically engages a female electrical connector 874 as indicated by the arrows in Figures 21 and 22. The door panel 812 is thereafter secured to the outer panel by any method described herein.
In any of the embodiments of the present invention, a secondary seal can be provided around the perimeter of the engagement between the door inner and outer panels. The seal can be formed with a seal gun, or a separately applied peel and stick seal can be used.
Any form of the seal has the additional advantage of isolating the door inner to minimize the occurrence of squeak and rattle.
Referring again to Figure 1, a wiring harness 58 carries electrical current to all necessary components, and includes plug-in connectors such as speaker connector 60, regulator connector 62, power lock connector 64, and connectors for any power mirror connected to flange 65. The harness 58 ls attached to . , ~ ......... .
CA 022~673~ 1998-ll-30 W097/45283 PCT~S97/09594--the door panel 12 as necessary, preferably by positioning some or all of its length within channels or hooks molded into the door panel or the belt line reinforcement. Door side impact components, such as a foam block 70 or an air bag, may also be secured to the door panel 12.
A male section 72 of a self-aligning and/or self-docking electrical connector may be mounted proximate the hinge side of the door panel 12 shown in Figure 1. Figure 5 shows the electrical connector comprised of the male section 72 mounted to the door panel 12 and a female section 140 mounted on a door outer panel 200. The male section 72 consists preferably of four spring-loaded contacts 142 having semi-spherical surfaces 143 located in a mounting plate 144 within a box 120. The female section 140 consists of the same number of inverted semi-spherical or crown shaped receptors 146. The receptors 146 can be made of beryllium copper alloy (BeCo) or other suitable material, and can be connected to a traditional electrical connector in the body of the motor vehicle.
During assembly, the installer simply translates the box 120 relative to the adjacent female section 140 until correctly positioned. At this point, the contacts 142 automatically fall into the receptors 146, thereby facilitating an electrical connection. A locator pin (not shown) can be provided in addition to the spherical contacts 142. The connector 72 shown in Figure 1 can be mated with an electrical extension 76 shown in Figure 4 as part of the door panel 12, or alternatively the extension 76 can be separately provided as part of a sheet metal door exterior for connection to the connector 72 as shown in Figure 6. Further details of the connector 72 can be found in U.S. patent application filed August 28, 1996 and titled Self-Aligning and Self-CA 022~673~ l998-ll-30 W097/45283 PCT~S97/09594 Docking Electrical Connector, assigned to the assignee of the present invention and hereby incorporated by reference. Instead of the electrical connector section 72, the harness 58 may be provided with a conventional pass through 78 including a seal 66 integral with the harness at the door-to-body pass through point to inhibit water seepage into the door cavity, as shown in Figure 2.
The assembled door assembly 10 is adapted for joining with the sheet metal door exterior by bringing it adjacent the door exterior, and locating the electrical connector section 72 with its mating section if so provided of the door exterior. The door assembly 10 is attached to the door exterior at the belt line with either a plurality of bolts or screws, or by separate plastic fasteners or fasteners integrally molded with the door panel, and finally securing the door assembly 10 around its periphery. One significant advantage of the door panel of the present invention, however, is that its electrical components can be tested prior to assembly with the door outer panel.
