DETAILED DESCRIPTION OF THE DRAWINGS

For the purposes of promoting an understanding of the principles of the present disclosure, reference is now made to the embodiments illustrated in the drawings, which are described below. The embodiments disclosed below are not intended to be exhaustive or limit the present disclosure to the precise form disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art may utilize their teachings. Therefore, no limitation of the scope of the present disclosure is thereby intended. Corresponding reference characters indicate corresponding parts throughout the several views.

The terms “couples”, “coupled”, “coupler”, and variations thereof are used to include both arrangements wherein two or more components are in direct physical contact and arrangements wherein the two or more components are not in direct contact with each other (e.g., the components are “coupled” via at least a third component, but still cooperate or interact with each other).

In some instances throughout this disclosure and in the claims, numeric terminology, such as first, second, third, and fourth, is used in reference to various operative transmission components and other components and features. Such use is not intended to denote an ordering of the components. Rather, numeric terminology is used to assist the reader in identifying the component being referenced and should not be narrowly interpreted as providing a specific order of components.

In some instances throughout this disclosure, positional relationships (e.g., top, bottom, right, left, front, back) may be used in reference to the described vehicle frame. Such use is intended to refer to typical use of the positional relationships. That is, a left view coincides with a perspective viewing the driver's side of the vehicle frame, i.e., the left side of the vehicle frame from the perspective of a driver (or passenger) seated within an operator area thereof. A right view is opposite of the left view. A front view coincides with a perspective viewing the vehicle frame head on from a position directly forward of the vehicle frame and a back, and a rear view is opposite of the front view. A top view coincides with a perspective viewing the vehicle frame from a top-down perspective from a position vertically above the vehicle frame and a bottom view is opposite of the top view.

Throughout this disclosure, fasteners used may be bolts, rivets, screws, hook and latch mechanisms, latches, pins, or other coupling methods as required or desired for a particular fastening application. Fasteners may be permanent, semi-permanent, or removable and reusable. Fasteners may also include joining methods such as welding (e.g., gas metal arc welding (GMAW), mig welding, tig welding, stick welding, sonic welding, plastic welding, laser welding, or another type of welding).

Vehicle frame 2 includes a plurality of frame members, as previously described. In various embodiments, each frame member described herein is made from at least one, and in some cases a plurality of, stamped frame pieces. In embodiments, at least one frame member may be cast, hydroformed, or manufactured by other methods. Each stamped frame piece may be created using any stamping technique, such as punching, blanking, bending, coining, embossing, and flanging. In embodiments, one or more stamped frame pieces may be created by a press-brake method. Further, each stamped frame piece may be created from a coil of sheet metal or a blank form of sheet metal. Each stamped frame piece may be created using a progressive die stamping method, a multi-slide stamping method, a deep drawing method or a short run stamping method.

Stamping allows for increased flexibility in design choices when creating frame members. Frame members may be created from two or more stamped frame pieces that are coupled together using one or more of adhesives, welds, spot welding, fasteners, other coupling methods, or combinations thereof. Frame pieces created by a stamping method allows for frame members to have variable cross-sectional widths and geometries along their lengths, and also allows for curves and bends that may otherwise be challenging to create using other manufacturing methods. In embodiments, stamping allows for members to be created using pieces of different materials, grades of materials, piece thickness, or the like. In embodiments, a frame member may be made of an outer frame piece and an inner frame piece, and the outer frame piece may be made of a softer material than the inner material so that the outer frame piece may absorb impacts better while the inner frame piece prevents intrusions from debris or the like.

Stamping frame pieces also allows for subassemblies of stamped frame pieces to be created which may then be used to create bigger portions of frame assemblies. Additionally, frame pieces may be created to have specific geometries that allow for integration and coupling with other frame pieces or components (e.g., a seal as further discussed below). Stamped frame pieces may be created with various embossed or bent portions. Various embossed portions may increase rigidity in the stamped components. In embodiments, a boss 125 (FIG. 12) is positioned adjacent first mounting portion 124 to increase the rigidity of upper A-pillar member 68.

While stamping characterizes a method of making a stamped part, a stamped part is also a structural characteristic distinct from parts which have been made by other processes (e.g., forging, casting, extrusion, etc.). For a person of ordinary skill in the art, a stamped component can be readily distinguished visually by its telltale tool marks, microstructurally by elongated grain structures and other microstructural characteristics, and mechanically by measures of hardness, ductility and the like for a given alloy.

As best seen in FIG. 14B, each of first joint 194, second joint 196, and third joint 198 includes a plurality of overlapping pieces to create a lap joint. That is, at first joint 194, each of first stamped frame piece 200 and second stamped frame piece 202 overlap at least a portion of at least one of first stamped frame piece 212 and second stamped frame piece 214. Further, at first joint 194, each of first stamped frame piece 212 and second stamped frame piece 214 overlap at least a portion of at least one of first stamped frame piece 200 and second stamped frame piece 202. A first line ‘A’ extends through first joint 194 at a first location and extends orthogonal to a top surface of first edge 260. The first line ‘A’ extends through each of first end portion 252 of first stamped frame piece 212, second end portion 224 of first stamped frame piece 200, and first end portion 240 of second stamped frame piece 214. A second line ‘B’ extends through first joint 194 at a second location and extends orthogonal to a top surface of second edge 232.

Overlapping first stamped frame piece 200, second stamped frame piece 202, first stamped frame piece 212, and second stamped frame piece 214 increases the strength of first joint 194 relative to non-overlapped joints.

Still referring to FIG. 14B, first joint 194 is created such that a generally continuous and flat surface is defined along and across a junction between first edge 260 and second edge 232. That is, second end portion 224 of first stamped frame piece 200 is shaped during the stamping process so that it may bend underneath first end portion 252 of first stamped frame piece 212 at first joint 194. Further, first end portion 240 of second stamped frame piece 214 is shaped during the stamping process so that it may bend underneath second end portion 224 of first stamped frame piece 200 and sandwich second end portion 224 between first end portion 240 of second stamped frame piece 214 and first end portion 252 of first stamped frame piece 212. As used herein, a generally continuous and flat surface is one that has minimal bumps, protrusions, and dips. A generally continuous and flat surface at a joint member has aesthetic benefits over frame members or pieces that have any protrusions, dips, or other inconsistencies in the surface of the joint. Additionally, for example, by bending second end portion 224 relative to first stamped frame piece 200, a shelf-like structure is created on second end portion 224 relative to first stamped frame piece 200 for first end portion 252 of first stamped frame piece 212 to sit within, which may simplify the assembly process and may otherwise increase consistency and repeatability of the assembly process.

Still referring to first joint 194 shown, e.g., in FIG. 14B, the outwardly facing frame pieces are first end portion 252 of first stamped frame piece 212 and first stamped frame piece 200. First joint member 104 is positioned vertically higher than upper A-pillar member 68 (FIG. 9), and first end portion 252 extends downwardly and over second end portion 224 of first stamped frame piece 200 which encourages any fluid that contacts first stamped frame piece 212 to flow downwardly in the direction of arrows 292 (FIG. 14B), past first joint 194. This arrangement of first stamped frame piece 212 and first stamped frame piece 200 reduces fluid intrusion into operator area 50 through first joint 194. Still referring to first joint 194, a generally continuous and flat surface is defined along and across a junction between third edge 258 and first edge 228 in substantially the same manner that a generally continuous and flat surface is defined along and across a junction between first edge 260 and second edge 232.

As best seen in FIGS. 14B-14C, at second joint 196 each of first stamped frame piece 208 and second stamped frame piece 210 overlap at least a portion of at least one of first stamped frame piece 212 and second stamped frame piece 214. Further, at second joint 196, each of first stamped frame piece 212 and second stamped frame piece 214 overlap at least a portion of at least one of first stamped frame piece 208 and second stamped frame piece 210. A third line ‘C’ extends through second joint 196 at a third location and extends orthogonal to a top surface of first edge 272. The third line ‘C’ extends through each of first end portion 270 of first stamped frame piece 208, second end portion 254 of first stamped frame piece 212, and first end portion 264 of second stamped frame piece 210. A fourth line ‘D’ extends through second joint 196 at a fourth location and extends orthogonal to a top surface of first edge 272. The fourth line ‘D’ extends through each of first stamped frame piece 212, second end portion 242 of second stamped frame piece 214, and first end portion 264 of second stamped frame piece 210. At least one spot weld is provided at the location of third line ‘C’ and at least one spot weld is provided at the location of fourth line ‘D’ to affix all the above-mentioned components to one another. In various embodiments, adhesive is placed between first end portion 270 and second end portion 254 and between first end portion 270 and first end portion 264 and between first stamped frame piece 212 and second end portion 242 and between second end portion 242 and first end portion 264. Overlapping first stamped frame piece 208, second stamped frame piece 210, first stamped frame piece 212, and second stamped frame piece 214 increases the strength of second joint 196 relative to non-overlapped joints.

Still referring to FIGS. 14B-14C, second joint 196 is created such that a generally continuous and flat surface is defined along and across a junction between first edge 272 and first edge 260. That is, second end portion 254 of first stamped frame piece 212 is shaped during the stamping process so that it may bend underneath first end portion 270 of first stamped frame piece 208 at second joint 196. Further, first end portion 264 of second stamped frame piece 210 is shaped during the stamping process so that it may bend underneath second end portion 254 and sandwich second end portion 254 between first end portion 270 and first end portion 264. Further, by bending second end portion 254 relative to first stamped frame piece 212, a shelf-like structure is created on second end portion 254 relative to first stamped frame piece 212 for first end portion 270 of first stamped frame piece 208 to sit within, which may simplify the assembly process and may otherwise increase consistency and repeatability of the assembly process. Still referring to second joint 196, the outer facing frame pieces are first end portion 270 of first stamped frame piece 208 and first stamped frame piece 212. First end portion 270 extends over second end portion 254 of first stamped frame piece 212 which encourages any fluid that contacts first stamped frame piece 212 to flow downwardly in the direction of arrows 292, past second joint 196. This arrangement of first stamped frame piece 208 first stamped frame piece 212 reduces water intrusion into operator area 50 through second joint 196. Still referring to second joint 196, a generally continuous and flat surface is defined along and across a junction between second edge 262 and second edge 274 in substantially the same manner that a generally continuous and flat surface is defined along and across a junction between first edge 260 and first edge 272.

Referring again to FIG. 14B, at third joint 198 each of first stamped frame piece 204 and second stamped frame piece 206 overlap at least a portion of at least one of first stamped frame piece 212 and second stamped frame piece 214 and each of first stamped frame piece 212 and second stamped frame piece 214 overlap at least a portion of at least one of first stamped frame piece 204 and second stamped frame piece 206. A fifth line ‘E’ extends through third joint 198 at a fifth location and extends orthogonal to a top surface of first edge 288. The fifth line ‘E’ extends through each of third end portion 244 of second stamped frame piece 214, third end portion 256 of first stamped frame piece 212, and first end portion 284 of first stamped frame piece 204. A sixth line ‘F’ extends through third joint 198 at a sixth location and extends orthogonal to a top surface of first edge 288.

Referring to FIG. 29, when the first joiner 92 is inserted into aperture 96 of lower B-pillar member 84, a plurality of fasteners 614 are configured to extend through a pair of apertures 613 in lower B-pillar member 84, apertures 434 of joiner 92 and bushings 436. That is, each of lower B-pillar member 84, joiner 92, and upper B-pillar member 72 are coupled together by fasteners 614. A similar coupling process is used for coupling the second joiner 93 between the upper B-pillar member 74 and lower B-pillar member 86.

Referring to FIG. 30, when the first third joiner 94 is inserted into lower C-pillar member 88, a plurality of fasteners 616 are configured to extend through a pair of apertures 615 in lower C-pillar member 88, apertures 570 of third joiner 94, and bushings 572. That is, each of lower C-pillar member 88, third joiner 94, and upper C-pillar member 76 are coupled together by fasteners 616. A similar coupling process is used for coupling the fourth joiner 95 between the upper C-pillar member 78 and lower C-pillar member 90.

In various embodiments, any or all of joiners 92, 93, 94, 95 may be permanently coupled to upper frame assembly 4 and selectively coupled to lower frame assembly 6. In various embodiments, any or all of joiners 92, 93, 94, 95 may be permanently coupled to lower frame assembly 6 and selectively coupled to upper frame assembly 4. In various embodiments, any or all of joiners 92, 93, 94, 95 may be selectively or permanently coupled to each of upper frame assembly 4 and lower frame assembly 6.

As illustrated in FIGS. 27A-30, joiners 92, 93, 94, 95 are coupling assemblies between upper frame assembly 4 and lower frame assembly 6. In various embodiments, joiners 92, 93, 94, 95 are registration features between upper frame assembly 4 and lower frame assembly 6, allowing for simpler assembly of upper frame assembly 4 onto lower frame assembly 6. In various embodiments, there are six locations for coupling upper frame assembly 4 to lower frame assembly 6, and two locations are configured for directly bolting upper frame assembly 4 to lower frame assembly 6 and four locations are configured to have joiners 92, 93, 94, 95 coupled between upper frame assembly 4 and lower frame assembly 6. That is, a plurality of the mounting locations (e.g., four mounting locations) have indirect couplings between upper frame assembly 4 and lower frame assembly 6 and a plurality of the mounting locations (e.g., two mounting locations) have direct couplings between upper frame assembly 4 and lower frame assembly 6.

Referring now to FIG. 31, joiner 92 is positioned between upper B-pillar member 72 and lower B-pillar member 84. Further, an upper portion of joiner 92 (e.g., upper portion 416 and upper portion 424) is positioned between first end portion 348 of second stamped frame piece 342 and first end portion 326 of first stamped frame piece 320 and a lower portion of joiner 92 (e.g., lower portion 414 and lower portion 422) is positioned between an outer stamped frame member 84A of lower B-pillar member 84 and an inner stamped frame member 84B of lower B-pillar member 84. Outer stamped frame member 84A extends upwardly and has an upper extent 636 and inner stamped frame member 84B extends upwardly and has an upper extent 634. Illustratively, first end portion 326 of first stamped frame piece 320 extends downwardly to a lower extent 638 that is positioned vertically lower than either of upper extent 634 or upper extent 636. Additionally, first end portion 326 is positioned exterior relative to both second stamped frame piece 342 and inner stamped frame member 84B and overlaps outer stamped frame member 84A such that first end portion 326 of first stamped frame piece 320 covers from an exterior, or outside perspective, the upper extent 636 of outer stamped frame member 84A. First end portion 326 of first stamped frame piece 320 provides additional scaling to mounting location 140 and in the event water, mud, other fluids, or debris flows down along mounting location 140, it will flow past mounting location 140, past first end portion 326 and on downwardly along outer stamped frame member 84A. Therefore, any water, mud, other fluids, or debris will be inhibited from flowing upwardly to upper extent 636 due to gravity as well as the tolerance between outer stamped frame member 84A and first end portion 326 thereby increasing the sealed nature of mounting location 140.

Referring again to FIG. 28, lower A-pillar member 80 includes an inner edge 618, first frame member 26 includes an inner edge 620, lower B-pillar member 84 includes a forward inner edge 622 and a rearward inner edge 624, second frame member 28 includes an inner edge 626, and lower C-pillar member 88 includes an inner edge 628. Illustratively, a generally continuous and flat surface is created around a first egress perimeter 630 defined by first edge 228 of upper A-pillar member 68, third edge 258 of left joint member 104, second edge 290 of frame member 54, second edge 336 of upper B-pillar member 72, forward inner edge 622 of lower B-pillar member 84, inner edge 620 of frame member 26, and inner edge 618 of lower A-pillar member 80. Further, a generally continuous and flat surface is created around a second egress perimeter 632 defined by first edge 334 of upper B-pillar member 72, second edge 386 of frame member 56, first edge 478 of upper C-pillar member 76, inner edge 628 of lower C-pillar member 88, inner edge 626 of frame member 28, and rearward inner edge 624 of lower B-pillar member 84.

In various embodiments, vehicle frame 2 is configured to receive a door 640, as shown in FIG. 33, which may be one of a plurality of doors to close in and/or surround operator area 50 and secure an operator and/or passengers within operator area 50. In various embodiments, door 640 is sealingly coupled to vehicle frame 2 to reduce, deter, or prohibit fluid and debris from entering into operator area 50 through door 640. Now referring to FIG. 32, a seal 650 includes a mounting portion 652 and a scaling portion 660. Mounting portion 652 is generally U-shaped and includes a first arm 654, a second arm 656 spaced from the first arm 654, and a plurality of tabs 658 on an inside of first arm 654 and second arm 656. Each of the tabs 658 are extending inwardly at least a portion of the distance between first arm 654 and second arm 656. Sealing portion 660 is generally arcuate shaped and extends outwardly from first arm 654 of mounting portion 652. In various embodiments, seal 650 is made of a resilient polymeric material. In various embodiments, seal 650 is made of a hard plastic, a polymer, a rubber, or another type of resilient material.

Referring now to FIG. 33, seal 650 is configured to be placed along various edges of vehicle frame 2. In various embodiments, seal 650 is configured to be placed around the entirety of first egress perimeter 630. That is, first arm 654 and second arm 656 of mounting portion 652 of seal 650 are configured to fit around both of second edge 336 of first portion 322 and second edge 352 of second stamped frame piece 342 of upper B-pillar member 72. Further, tabs 658 of first arm 654 and second arm 656 provide frictional adherence to each of second edge 336 and second edge 352 in order to couple seal 650 to upper B-pillar member 72. In various embodiments, seal 650 is an extruded component. Further, seal 650 is a uniform seal cut to a length approximately equal to that of the length of first egress perimeter 630. First egress perimeter 630 is a generally continuous and flat surface, which allows a single, uniform seal to be placed around first egress perimeter 630. Seal 650 may be coupled to first egress perimeter 630 through solely frictional adherence, however, seal 650 may also be coupled to first egress perimeter 630 through an adhesive or other bonding method. Scaling portion 660 of the seal 650 on first egress perimeter 630 extends generally towards an exterior of vehicle frame 2, away from operator area 50.

Still referring to FIG. 33, door 640 is shown in a closed position. Door 640 is rotatably coupled to vehicle frame 2 (e.g., about first A-pillar 8). Door 640 includes a first portion 642 and a second portion 644. In various embodiments, second portion 644 is generally an edge of door 640. Illustratively, first portion 642 is configured to engage a first seal 650 on first egress perimeter 630 and second portion 644 is configured to receive a second seal 650. The scaling portion 660 of the second seal 650 extends towards an interior of vehicle frame 2, towards operator area 50, and sealing portion 660 is configured to engage first portion 322 of upper B-pillar member 72. When door 640 is in a closed position, a double seal is created, and each of the first seal 650 and the second seal 650 are sealing the operator area 50 from an exterior of vehicle frame 2. Further, first seal 650 is configured to engage a flat surface (e.g., a flat surface on first portion 642 of door 640) and second seal 650 is configured to engage a flat surface (e.g., first portion 322). Allowing each seal 650 to contact a flat surface increases the effectiveness of each seal 650 and reduces the chances of intrusion through both seals.

In various embodiments, each seal 650 is configured to compress under the force of door 640 closing, and to remain in a compressed or deformed state when door 640 is latched or otherwise retained in its closed position. Seal 650 is configured to compress a predetermined amount, or distance, which provides additional range of motion for door 640 to rotate when approaching the closed position. Additional range of motion for door 640 to rotate when approaching the closed position increases the potential range of locations that door 640 may latch when approaching the closed position. This improves the user experience by enhancing the user feel of latching door 640 and increases the repeatability and consistency of closing door 640.

In various embodiments, vehicle frame 2 is created so that each egress perimeter 630, 632 (and corresponding egress perimeters on passenger side, or right portion 168) has a generally continuous and flat surface, allowing seal 650 to be adequately coupled to each of the egress perimeters. That is, a plurality of doors 640 (e.g., driver, passenger, rear driver, rear passenger) may be coupled to vehicle frame 2, and each of door 640 may be sealingly coupled to vehicle frame 2 with double seals (e.g., FIG. 33). Similarly, forward opening 52 includes a generally continuous and flat surface around perimeter 318, and a seal 650 may be coupled along the perimeter 318 so that a windshield or other accessory may be coupled to forward opening 52. Similarly, a second seal 650 may be coupled to an accessory windshield so that a double scal may be created at forward opening 52. Further, a rear window perimeter 684 is created by each of upper C-pillar member 76, first member 116, second member 118, upper C-pillar member 78, and rear wall 64. A seal 650 may be coupled along rear window perimeter 684 so that a rear windshield or other accessory may be coupled to a rear of vehicle frame 2, around rear window perimeter 684. Similarly, a second seal 650 may be coupled to an accessory rear windshield so that a double seal may be created around a rear windshield at rear window perimeter 684.

Still referring to FIG. 33, upper B-pillar member 72 is shaped such that first egress perimeter 630 is recessed towards the interior of vehicle frame 2 relative to first portion 322. That is, first egress perimeter 630 is spaced from first portion 322 by a first distance 646, meaning that seal 650 on first egress perimeter 630 is positioned inwardly relative to first portion 322. Further, first portion 642 of door 640 has a width 648 that is approximately equal to first distance 646. Second portion 644 of door 640 has a smaller width than first portion 642. As seen in FIG. 33, door 640 can be rotated to a closed position such that at least a portion of door 640 is recessed inwardly toward the interior relative to first portion 322. Vehicle frame 2 has a slimmer profile when door 640 is recessed relative to first portion 322 (i.e., an outer face of vehicle frame 2) which reduces the overall width of the vehicle and increases the visual aesthetic of the vehicle. Further, first portion 642 is then positioned closer to longitudinal centerline 120 than second portion 644.

Referring now to FIGS. 34A-34D, a door ring 662 may be constructed and assembled in a variety of ways in order to meet certain shipping, manufacturing, assembly, and/or aesthetic considerations. In various embodiments, it may be desirable for door ring 662 to be constructed of as few pieces as possible to increase the aesthetic appeal of door ring 662. In various embodiments, it may be desirable to create door ring 662 in a plurality of pieces to decrease shipping size.

Referring to FIG. 34A, door ring 662 includes first A-pillar 8 which includes lower A-pillar member 80, upper A-pillar member 68 and first joint member 104. Door ring 662 also includes first B-pillar 12 which includes upper B-pillar member 72 and lower B-pillar member 84, as well as first C-pillar 16 which includes upper C-pillar member 76 and lower C-pillar member 88. Fifth frame member 54 extends between first joint member 104 and upper B-pillar member 72, first frame member 26 extends between lower A-pillar member 80 and first B-pillar 12, sixth frame member 56 extends between upper B-pillar member 72 and upper C-pillar member 76, and second frame member 28 extends between first B-pillar 12 and first C-pillar 16. As previously discussed, any or all of the components of door ring 662 are stamped frame members and may be comprised of one or more stamped frame pieces.

Referring now to FIG. 34B, an alternative door ring 664 includes a single frame member 668 which includes an alternative construction of an A-pillar 8′, a B-pillar 12′, and a C-pillar 16′.

Further, first lower B-pillar 1404 includes a first stamped frame piece 1454 (similar to outer stamped frame member 84A (FIG. 31)) and a second stamped frame piece 1456 (similar to inner stamped frame member 84B (FIG. 31)). In embodiments, first lower B-pillar 1404 is substantially similar to and/or constructed substantially similar to lower B-pillar member 84 (FIG. 29).

Still referring to FIG. 51, first joiner 1032 may be assembled with each of second upper B-pillar 1014 and first lower B-pillar 1404 in a substantially similar manner to first joiner 92 being assembled with each of upper B-pillar member 72 and lower B-pillar member 84. In embodiments, first frame piece 1412 is coupled to second frame piece 1430, as previously disclosed, to create first joiner 1032. Coupler 1032 is coupled to one or both of first stamped frame piece 1450 and second stamped frame piece 1452 of first upper B-pillar 1012 by one or more spot welds and/or adhesives between first joiner 1032 and one or both of first stamped frame piece 1450 and second stamped frame piece 1452 (e.g., at first flange 1440, second flange 1442, first body portion 1432, or first body portion 1414). Further, coupler 1032 may then be inserted into first lower B-pillar 1404 so that the bottom portion of first joiner 1032 (e.g., second body portion 1416 and second body portion 1434) are positioned between first stamped frame piece 1454 and second stamped frame piece 1456. A first fastener 1466 may extend through apertures 1418, spacers 1462, and apertures 1435 and a second fastener 1468 may extend through apertures 1419, spacers 1464, and apertures 1437 to couple first lower B-pillar 1404 to first joiner 1032 and join first lower B-pillar 1404 and first upper B-pillar 1012. In embodiments, the extensions 1424, 1426, 1428, 1444, 1446, 1448 are all angled inwardly towards each other to create a chamfered lower portion of first joiner 1032, which acts as a locating feature during assembly of first joiner 1032 with first lower B-pillar 1404 (e.g., when first joiner 1032 is lowered into first lower B-pillar 1404).

Referring still to FIG. 51, each of first stamped frame piece 1450 and first stamped frame piece 1454 define an outer profile 1472 of B-pillar (e.g., first upper B-pillar 1012 and first lower B-pillar 1404). In embodiments, the outer profile 1472 of the B-pillar is curved (e.g., outwardly convex) to achieve a preferred aesthetic of the B-pillar. In embodiments, the outer profile includes a plurality of recesses. That is, first stamped frame piece 1454 includes a first recess 1458 and a second recess 1460, and first recess 1458 receives a head of first fastener 1466 and second recess 1460 received a head of second fastener 1468 to recess the fastener within the outer profile 1472 of the B-pillar. Further, when first joiner 1032 is inserted into first lower B-pillar 1404, as described above, second body portion 1416 contacts, or is closely mated with, first recess 1458 and second recess 1460. That is, second body portion 1416 is angled relative to first body portion 1414 and second body portion 1434 is angled relative to first body portion 1432 such that each of second stamped frame piece 1456, second body portion 1434, second body portion 1416 are generally parallel with each of recesses 1458, 1460. Fasteners 1466, 1468 then have parallel clamp surfaces, allowing for a stronger, more durable connection to be made by fasteners 1466, 1468. In embodiments, the bottom portion of first joiner 1032 (e.g., second body portion 1416, second body portion 1434) is generally perpendicular to a ground level (e.g., the engagement plane of ground engaging members on a flat surface) and the upper portion of first joiner 1032 (e.g., first body portion 1414, first body portion 1432) is angled relative to the ground level.

Still referring to FIG. 51, first upper B-pillar 1012 and first lower B-pillar 1404 are coupled together such that first stamped frame piece 1450 of first upper B-pillar 1012 extends over first stamped frame piece 1454 of first lower B-pillar 1404 on an exterior side of the B-pillar to create a lapped connection 1470. The lapped connection 1470 increases the water resistance of the joint between first upper B-pillar 1012 and first lower B-pillar 1404 because fluid or other debris will naturally drain down the side of first stamped frame piece 1450, down across lapped connection 1470, and down the side of first stamped frame piece 1454, and fluid or other debris will be inhibited from flowing upwardly through lapped connection 1470 and into space between the outer members of the B-pillar (e.g., first stamped frame piece 1450, first stamped frame piece 1454) and the inner members of the B-pillar (e.g., second stamped frame piece 1452, second stamped frame piece 1456).
