Retractable top quarter window assembly

TECHNICAL FIELD

[0002] This invention relates to retractable hard top vehicle roofs and related vehicle components that facilitate roof retraction and extension.

BACKGROUND ART

[0003] Motor vehicles generally are provided with a rigid roof structure completely enclosing the top of the passenger compartment. In some instances a sunroof may be provided at an additional cost to provide some overhead ventilation, however, the size of the vehicle sunroofs is normally very limited. Vehicle roofs with sunroofs do not in any way approach the ventilation, openness and panoramic view that is available with a convertible roof.

[0004] Conventional convertibles have a soft top that is folded into a series of folds that are stretched over three or four convertible top bows when the top is in its extended, or up, position. Convertible soft tops are prone to problems including excessive noise and potential water leakage. Soft tops are also generally less durable than a hard top and may require replacement periodically during the life of the vehicle. Some of the difficulties with the soft top convertibles result from the fact that they are not particularly well suited to winter weather. Cold temperatures, ice and snow that are encountered in winter discourage consumers from selecting convertible style vehicles even though the consumers may want a convertible for summer driving. In winter, water leakage through the convertible roof can make driving unpleasant and cause water damage to the interior of the vehicle. A soft top can make a vehicle difficult to heat due to heat transfer through the convertible top unless it is lined and insulated. If a convertible top is lined and insulated, reduction in noise levels and better heat retention may be achieved but the top becomes more bulky and requires more space within the vehicle for stowage.

[0005] Retractable hard tops offer the advantages of a hard top roof and a convertible in that they provide a durable vehicle roof that is not prone to excessive noise levels or leakage and provides excellent durability. However, retractable hard tops generally require complex linkages and drive mechanisms. For example, U.S. Pat. No. 5,823,606, discloses a system in which the trunk is provided with a dual hinge mechanism to allow it to be opened in the conventional manner on a forward hinge and to be tipped about its rear edge on an auxiliary rear hinge. In addition, a relatively large storage compartment must be provided to permit the retractable hard top to be folded and then moved into its storage compartment. Depending upon the size of the roof and trunk area of the vehicle, it may be difficult or impossible to configure a retractable hard top according to prior art designs that would still leave sufficient space in the trunk for useful storage. In addition to providing space for storing the retractable hard top, if an automatic hard top is provided, there must be adequate clearance between the trunk lid, wheel housings, floor of the vehicle and belt line of the vehicle so that the hard top may be automatically retracted without interference from other vehicle elements.

[0006] Assembly of convertible tops and retractable hard tops has generally been accomplished by taking separate components including the top and its associated linkage and the tonneau and its associated linkage and assembling them to a partially constructed vehicle on an assembly line. Alternatively, convertibles have been manufactured by removing the roof structure of a conventional coupe, reinforcing the frame and then installing the convertible top and tonneau. In either method the trunk lid is assembled as part of the vehicle entirely separately from the top. Likewise, if a roll bar is provided it is entirely separate from the top and from the trunk lid prior to assembly to the vehicle. These assembly methods are inefficient and add operations to the final vehicle assembly process. Also, testing and adjustment of various systems relating to the operation of the trunk lid, tonneau and top are required post assembly to the vehicle including integration of electrical connections, hydraulic systems and mechanical linkages.

[0007] These and other problems and design objectives are addressed by the present invention as summarized below.

DISCLOSURE OF INVENTION

[0008] The advances embodied in the present invention may be applicable to retractable hard tops and soft convertible tops. The present invention includes improvements in the top alone and in combination with a power tonneau cover, trunk lid, and rollbar. The invention also offers advantages relating to modular assembly techniques involving the retractable top, trunk, tonneau and rollbar.

[0009] According to one aspect of the present invention, a retractable top system is disclosed for a vehicle that has a body and a passenger compartment. The vehicle top system includes a roof formed in at least two sections that are pivotally connected to each other and to the vehicle body and are movable between a top up position and a stowed position by a roof linkage. The roof linkage includes right and left pivot brackets that each have first and second portions pivotally connected respectively to the roof sections and a third portion pivotally and slidably connected respectively to right and left roof guide tracks. In the top up position, the roof covers a passenger compartment. In the stowed position, the passenger compartment is uncovered. The two sections of the roof are adjoined in the top up position and are folded together in the stowed position. The roof pivot brackets are moved along roof guide tracks as the roof is moved between the top up position and the stowed position. The system is preferably powered by a motor that is operatively connected to the roof linkage for moving the top between the top up and stowed positions.

[0010] The retractable top linkage includes a front roof assembly a rear roof assembly that are connected by right and left balance links. Each balance link pivotally connects one side of the front roof assembly to one of the first and second portions of the right and left roof pivot brackets to provide a balance link pivot mount. The linkage further includes right and left control links that are connected to right and left body mounted pivots on a first end and to a controlled member on a second end. The control member is pivotally connected to the right and left roof pivot brackets respectively. The controlled member may be either a pivotal connection at a lower intermediate portion of the rear roof assembly or may be a pivot connector on the balance link that extends between the front roof assembly and roof pivot brackets.

[0011] The roof pivot brackets each guide movement of the front and rear roof assemblies. The right and left roof pivot members connect the roof pivot brackets for movement relative to the right and left roof guide tracks. The balance links connect the roof pivot brackets to the front roof assembly to move the front and rear roof assemblies between their top up and folded positions. The rear roof pivot mounts of the roof pivot brackets guide the lower edge of the rear roof assembly along the right and left roof guide tracks forward and downward into a storage compartment of the trunk as the front roof assembly is folded toward the rear roof assembly.

[0012] According to another aspect of the invention, a rear quarter window assembly for a vehicle is provided that is carried by the retractable top. The rear quarter window is carried by the retractable top as the top is moved between a closed position and a stowed position. In the closed position, the window is contiguous with the belt line of the vehicle to cover an opening defined between the top and the belt line of the vehicle. In the stowed position, the window is carried by a retractable top but is not contiguous with the retractable top or the belt line of the vehicle. The window/top control arm is pivotally connected to a rear portion of the retractable top and is pivotally connected to the rear quarter window. A cam pivotally connects a lower portion of the rear quarter window to the retractable top. The rear quarter window is moved by the retractable top after the retractable top moves clear of the rear quarter window. The rear quarter window is rotated by the window/top control arm about the cam.

[0013] According to another aspect of the invention as it relates to the rear quarter window assembly, a longitudinally extensible roller cam pivotally connects a lower rear corner of the rear quarter window to the retractable top. The rear quarter window is moveable laterally outboard of the retractable top by extension of the roller cam to allow the retractable top to move clear of the rear quarter window. The rear quarter window is rotated by the window/top control arm about the roller cam to a position laterally outboard of the retractable top.

[0014] According to another aspect of the invention, a retractable vehicle top, trunk lid and tonneau cover assembly may be provided in combination for a vehicle including many of the structural elements previously described with respect to each element separately. Likewise, a retractable vehicle top, rear quarter window, tonneau cover assembly may be provided as a system incorporating the structural elements previously described with respect to each of the components.

[0015] These and other aspects of the present invention will be better understood in view of the attached drawings and detailed description of several embodiments of the invention that follows.

BEST MODE FOR CARRYING OUT THE INVENTION

[0044] Referring now to FIG. 1, a retractable top 10 for a vehicle 12 is shown as a modular construction including a frame 14, inner tonneau cover 16 and trunk lid 18 that are installed as a unit in the partially assembled vehicle 12. The frame 14 is secured to the retractable top 10, inner tonneau cover 16 and trunk lid 18 that will be more particularly described below. The trunk lid 18 includes an outer tonneau cover 20 that is assembled to the trunk lid 18 in a sliding relationship similar to the sliding mechanism used for power sunroofs. The front edge of the trunk lid 22 and a rear edge of the inner tonneau 24 define the space covered by the outer tonneau cover 20 when it is extended from the trunk lid 18. Main bracket 26 and right and left wheel housing brackets 28 and 30, respectively, are secured to or are formed as parts of other components of the vehicle such as the floor and wheel housings. Holes 32 are provided for fasteners to be received in for securing the modular assembly to the vehicle 12.

[0045] Referring to FIGS. 2-8, the structure and operation of the retractable roof 10 is described. The retractable top 10 in the illustrated embodiment includes a front roof assembly 36 and a rear roof assembly 38. The front and rear roof assemblies 36 and 38 are interconnected by a hinge pin 40 and hinge flange 42. The hinge pin 40 is associated with the rear roof assembly 38 and the hinge flange 42 extends rearwardly from the rear edge of the front roof assembly 36. The roof linkage generally indicated by reference numeral 44 controls retraction and extension of the retractable top 10. The roof linkage 44 is symmetrical and includes right and left roof linkages on the right and left sides of the vehicle 12. For brevity, only the left side of the roof linkage 44 is shown. However, it should be understood that a right side linkage is also provided as part of the roof linkage 44. The right side roof linkage is substantially identical in all material respects to the left side linkage and its description will not be repeated.

[0046] The roof linkage 44 includes a roof pivot bracket 46 comprising a generally y-shaped member having a track follower member 48 on one part of the roof pivot bracket 46 that is received for sliding movement along the roof guide track 50. A pivot connector 52 is provided on another portion of the roof pivot bracket 46. The pivot connector 52 connects the roof pivot bracket 46 to the rear roof assembly 38. A pivot pin 54 connects another part of the roof pivot bracket 46 to a balance link 56. Balance link 56 interconnects the roof pivot bracket 46 to the front roof assembly 36 at front roof pivot 58. A control link 60 is connected to a body mount pivot 62 and a roof assembly pivot 64.

[0047] A rear quarter window 66 spans the space between the belt line 68 of the vehicle 12 and the lower edge 70 of the rear roof assembly 38. A window/top control arm 72 is connected by pivot 74 to the rear roof assembly. Pivot 76 connects the other end of the window/top control arm 72 to the rear quarter window 66. A roller cam 78 is connected to the rear quarter window 66 and is longitudinally extensible to move the rear quarter window 66 outboard as the roof is retracted and is longitudinally retracted to move the rear quarter window 66 into engagement with the belt line 68 and lower edge 70 of the rear roof assembly 38 when the top 10 is in the top up position.

[0048] Referring now to FIG. 2, the roof pivot bracket 46 is located at the upper and rear end of the roof guide track 50 and the rear quarter window 66 is in engagement with the belt line 68 and edge 70 of the rear roof assembly 38. The front roof assembly 36 and rear roof assembly 38 are contiguous to form a hard top over the passenger compartment of the vehicle.

[0049] As shown in FIG. 3, the roof is in an early stage retraction position wherein the roof pivot bracket 46 has begun to move downwardly and forwardly in the roof guide track 50. The rear quarter window is extended outwardly to provide clearance between the window 66 and the outboard sides of the retractable top 10. The roof pivot bracket 46 is held in the same angular orientation by the track follower member 48 in the roof guide track 50. The front roof assembly 36 and rear roof assembly 38 are not contiguous at this phase of the retraction cycle but are held together by the hinge pin 40 and hinge flange 42 as they begin folding toward each other. The balance link 56 holds the front roof assembly 36 in a generally horizontal orientation. The balance link 56 is held in place by the roof pivot bracket 46. The rear roof assembly 38 is rotated upwardly on its front end and downwardly on its rear end by the movement of the pivot connector 52 and the control link 60. Control link 60 is anchored to the vehicle at the body mount pivot 62 and is rotated about roof assembly pivot 64. The rear quarter window 66 is rotated by the window/top control arm 72 that is connected to the rear roof assembly 36 at pivot 74. The window is connected to the window/top control arm by pivot 76 that rotates the rear quarter window 66 about the roller cam 78.

[0050] Referring now to FIG. 4, the retraction of the roof has continued to its approximate midpoint wherein the roof pivot bracket 46 has been moved by a cylinder or motor to the approximate midpoint of the roof guide track 50. The front roof assembly 36 is held in its generally horizontal orientation by the balance link 56 while the rear roof assembly has been rotated to a partially inverted position by the pivot connector 52 on the roof pivot brackets 46. The control arm 60 supports the rear roof assembly on the body mount pivot 62 as it rotates about the roof assembly pivot 64. The rear quarter window 66 is rotated by the window/top control arm 72 about the roller cam 78.

[0051] Referring now to FIG. 5, the action of the roof linkage 44 is continued to a fully retracted position and the pivot bracket 46 has moved further downwardly and forwardly on the roof guide track 50. The balance link 56 continues to hold the front roof assembly in a generally horizontal orientation as it is further folded on the hinge pin 40 and hinge flange 42 over top of the rear roof assembly 38. The rear roof assembly 38 is nearly inverted as it is rotated by the further forward advancement of the pivot connector 52 and rotated about the roof assembly pivot 64. The control link 60 moves in a clockwise direction about the body mount pivot 62. The window/top control arm 72 continues to rotate the rear quarter window 66 about the roller cam 78 that holds the window outboard of the retractable top 10 as it progresses through its retraction cycle.

[0052] Referring now to FIG. 6, the retractable top 10 is shown in its fully retracted position. The roof pivot bracket 46 is at the forward and downward end of the roof guide track 50. The roof pivot bracket 46 is held in the same angular orientation by the track follower members 48 to the roof guide track 50. The control arm 56 continues to hold the front roof assembly in a generally horizontal orientation while the rear roof assembly 38 has been inverted so that the front roof assembly 36 may rest on the rear roof assembly 38. The hinge pin 40 and hinge flange 42 connect the front roof assembly 36 and rear roof assembly 38 together. The control arm 60 is disposed in a generally downward orientation suspending the rear roof assembly 38 on the roof assembly pivot 64 from the body mount pivot 62. The window/top control arm 72 is moved by the control arm 60 to a substantially inverted position relative to its position in the top up position.

[0053] When the roof is in its retracted position, as shown in FIG. 7, it may be covered by the inner tonneau cover 16 and an outer tonneau cover 20 on the trunk lid 18 of the vehicle 12. The front roof assembly 36 and rear roof assembly 38 are shown folded against one another.

[0054] Referring now to FIG. 8, the tonneau parts of the retractable top are shown in exploded perspective. A drive 80 is shown that is connected to the vehicle body on one end and the pivot bracket 46 on the other end. The drive 80 may be a cylinder, cable drive, motor driven screw drive or other device that is capable of moving the roof pivot bracket 46 within the roof guide tracks 50. The track follower member 48 is shown as an extruded t-shaped member formed on one part of the roof pivot bracket 46. To reduce friction, the track follower member 48 may include a roller or other friction reducing structure. The front roof assembly 36 includes the hinge flange 42 that is connected to the rear roof assembly by the hinge pin 40. Balance link 56 is connected by pivot pin 54 to the roof pivot bracket 46 on one end while the front roof pivot 58 connects the balance link 56 to the front roof assembly 36. Window/top control arm 72 is connected a pivot 74 to the control link 60 on one end and is connected to the pivot 76 on the rear quarter window 66. Rear quarter window 66 is further controlled by the roller cam 78 about which it pivots and that is effective to move the window outward during the retraction and extension cycles.

[0055] Referring now to FIGS. 9-11, an alternative embodiment of the roof retraction mechanism is described that is similar in many respects to the embodiment of FIGS. 2-8 but includes a different arrangement wherein the control link 82 is connected to the body mount pivot 62 on one end and is connected by a pivot 84 on the balance link 56. The control link 82 connects the balance link 56 to the vehicle at body mount pivot 62. The balance link 56 is connected by pivot pin 54 to the roof pivot bracket 46 on its lower end and to the front roof pivot 58 on the other end. In FIG. 9, the retractable top 10 is shown in its top up position. In FIG. 10, the alternative embodiment is shown with the roof at the approximate midpoint of the retraction cycle. In FIG. 11, the roof is shown in its fully retracted position with the control link 82 suspended from the body mount 62 and supporting the balance link 56.

[0056] Referring now to FIGS. 12-14, the inner tonneau cover in combination with the retractable top is shown and its operation is described in conjunction with the operation of the top. A front pivot flange 90 extends from the inner tonneau cover 16 and is connected by a pivot pin 92 to the vehicle body. A rear pivot link flange 94 also extends downwardly from the inner tonneau cover 16 and is connected by a pivot link pin 96 to bell crank 98. Bell crank 98 is connected by pivot connector 100 to the roof pivot bracket 46. Roof pivot bracket 46 has previously been described as it relates to the roof retraction mechanism. A front tonneau cover control link 102 interconnects the rear pivot link flange 94 to the bell crank 98 at pivot pin 104. Rear tonneau cover control link 106 interconnects the bell crank 98 to a rear tonneau cover control link flange 108 that extends downwardly from the lower edge of the rear roof assembly 38 when the rear roof assembly 38 is in its top up position. The bell crank pivot 110 connects the rear tonneau cover control link 106 to the bell crank 98.

[0057] When the retractable top 10 is in its top up position, the inner tonneau cover 16 is preferably maintained in a generally horizontal orientation as shown in FIG. 12. On the beginning of the retraction cycle, the inner tonneau cover 16 is moved to a generally vertical position to provide clearance for the passage of the retractable top 10. The inner tonneau cover 16 pivots on pivot pin 92 in a counter clockwise direction as viewed from the left side of the vehicle. The front tonneau cover control link 102 is driven by movement of the bell crank 98 in a downward and forward direction as the roof pivot bracket 46 is moved along the roof guide tracks 50 with the roof pivot bracket being guided in the roof guide tracks 50 by track follower members 48. As the front tonneau cover control link 102 is moved by the bell crank to a position in front of the pivot pin 92, the inner tonneau cover 16 is pulled down to a generally horizontal orientation as shown in FIG. 14. Rear tonneau cover control links 106 connect the bell crank 98 to the rear tonneau cover control link flange 108. The bell crank rotates and carries the rear tonneau cover control link 106 that in turn supports the rear roof assembly 38. The bell crank 98 transfers the motive force of the rear roof assembly 38 to the tonneau cover and coordinates the movement of the retractable top 10 with the inner tonneau cover 16.

[0058]
FIG. 15 is an exploded perspective view of the left side of the inner tonneau cover and its associated linkage to the retractable top 10. The drive illustrated in FIG. 15 is a hydraulic cylinder 81. The front pivot flange 90 and rear pivot link flange 94 are shown on the underside of the inner tonneau cover 16. Front tonneau cover control link 102 connects the rear pivot link flange 94 to the bell crank 98. Bell crank 98 includes three connection points. One connecting the bell crank 98 to the front tonneau cover control link 102, another connecting the bell crank 98 to the rear tonneau cover control link 106, and a third comprising pivot connector 112 connecting the bell crank 98 to the roof pivot bracket 46. Operation of the retractable top 10 and inner tonneau cover was previously described with reference to FIGS. 12-14.

[0059] Referring now to FIGS. 16-19, the trunk lid assembly for a vehicle 12 and retractable top 10 is shown. Right and left sides of the trunk assembly are shown in FIG. 19 with the reference numerals for the left side of the vehicle being duplicated by the same reference numerals with a prime designation designating the corresponding parts on the right side of the vehicle. A description of the structure and operation of the trunk lid assembly will be made with reference to the left side with the understanding that the right side is a mirror image of the left side. The trunk lid 18 is connected by arcuate support arms 120 at the back end 122 of the arcuate support arms 120.

A control arm 134 is connected to the vehicle or to the frame 14 in a modular construction by pivot body connector 136 and is connected to the arcuate support arm 120 by a pivot arm connector 140. In the embodiment of FIGS. 24-27, the drive mechanism is a drive cylinder 160 connected between arcuate support arm 120 and control arm 134. The drive cylinder 160 is connected to an opening 162 on the control arm 134 and is connected to an opening 164 on arcuate support arm 120. The drive cylinder 160 contracts as the trunk lid is lifted and is expanded as the trunk lid is closed, as shown in FIG. 22.

[0063] Referring now to FIG. 28, a trunk lid 18 is shown to include a rear tonneau cover 20 that is slidably received on tracks 172 and 172′. The outer tonneau cover 20 extends outwardly from the front edge 22 of the trunk lid 18 to expand the gap formed between the rear edge 24 of the inner tonneau cover 16 when it is in its horizontal position and the front edge 22 of the trunk lid 18. The outer tonneau cover is moved by a motor 174 and cables 176 on both sides of the trunk lid to move the outer tonneau 20 in the tracks 172 and 172′. The operation of the outer tonneau cover drive is similar in many respects to a sunroof drive wherein the outer tonneau slides and is lifted on links 178 when extended to be flush with the trunk lid 18.

[0064] While several embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
