Abstract
A multi-panel sunroof employs at least three movable sunroof panels. In another aspect of the present invention, three sunroof panels are stacked upon each other in one or two different operating positions. A further aspect of the present invention provides for rearward opening movement of a front sunroof panel and forward opening movement of a rear sunroof panel.
Description
- This application is a divisional of U.S. patent application Ser. No. 11/316,382 filed on Dec. 22, 2005. The disclosure of the above application is incorporated herein by reference.
- The present invention relates generally to automotive vehicle sunroofs and more particularly to a multi-panel sunroof system.
- It is common to employ single-panel sunroofs in automotive vehicles. More recently, various attempts have been made to increase the sunroof opening area in vehicles to maximize open roof area above all of the vehicle passengers especially as the front windshield header continues to move rearwardly for styling and aerodynamic reasons. For example, various multi-panel sunroofs have been considered to increase open roof area and are disclosed in the following U.S. Pat. Nos.: 5,746,475 entitled “Drive Mechanism for an Automotive Vehicle Sunroof Assembly” which issued to Caye et al. on May 5, 1998; 5,197,779 entitled “Power Sliding Sunroof” which issued to Mizuno et al. on Mar. 30, 1993; and 5,029,937 entitled “Roof System for Vehicle” which issued to Yamamoto on Jul. 9, 1991; all of which are incorporated by reference herein. While some of these patents offer significant improvements, the sunroof tracks take up considerable vertical space thereby encroaching on desired headroom of the vehicle occupants, and do not provide vertical access above the storage area of a sport utility vehicle or station wagon.
- In accordance with the present invention, a multi-panel sunroof employs at least three movable sunroof panels. In another aspect of the present invention, three sunroof panels are stacked upon each other in one or two different operating positions. A further aspect of the present invention provides for rearward opening movement of a front sunroof panel and forward opening movement of a rear sunroof panel. Yet another aspect of the present invention provides for a unique locking member and hook structure of a sunroof movement mechanism. An additional aspect of the present invention sunroof system includes a sunroof slide block having a body, a diagonally extending camming surface, an opening therebetween, and a trailing ramp. A method of operating a sunroof system is also provided.
- The multi-panel sunroof system of the present invention is advantageous over traditional constructions in that the present invention system employs a track having reduced vertical depth in order to maximize occupant head room within the vehicle. The present invention is further advantageous by maximizing opening area above the front and rear seat passengers while also allowing vertical opening access over the storage area of the vehicle, such that cargo can be stored therein and extend above the nominal roof plane. Furthermore, various embodiments of the present invention employ in-line, multi-panel tracks along each side rail of the vehicle which allows for the multiple sunroof panels to be substantially co-planar when closed (while being slightly curved to account for the normal vehicle styling curvature). The single common track on each vehicular side also reduces tooling and assembly costs, while reducing parts in an assembly plant. Additional advantages and features of the present invention will become apparent from the following description and appended claims, taken in conjunction with the accompanying drawings.

FIGS. 1 and 2 show allsunroof panels FIGS. 3 and 4 showfront sunroof panel 63 in its upwardly tilted venting position, to allow some air flow through an open space adjacent a rear edge thereof, while central andrear sunroof panels FIGS. 5 and 6 illustratefront sunroof panel 63 rearwardly moved to an intermediate open position, in a spoiler-type orientation stacked above the closedcentral sunroof panel 67, whilerear sunroof panel 71 is in its closed position.FIGS. 7 and 7A show front andcentral sunroof panels FIG. 6 , butrear sunroof panel 71 is forwardly moved to its open position dropped belowcentral sunroof panel 67 in a three panel stacked configuration. Moreover,FIGS. 8 and 9 illustrate the same three panel stacked configuration but withfront sunroof panel 63 moved to its extended open position,central sunroof panel 67, rearwardly moved to its open position, andrear sunroof panel 71 in its closed position. Finally,FIGS. 10 and 11 represent front andcentral sunroof panels rear sunroof panel 71 moved to its open position to allow vertical cargo passage to a cargo area through a nominal roof plane or to allow open air space above a third passenger seating row. In at least some operating conditions, front andrear sunroof panels central sunroof panel 67 is passively driven by movement offront sunroof panel 63. - Referring to
FIGS. 12 , 13, 21B, 21C, 21D, 24B, 25, 28B, 29B and 41, a singleextruded track 101 is mounted to each side rail of the stationary vehicular roof and elongated in a predominantly fore-and-aft longitudinal direction. Thus, a single common track is used for all of the left-hand movement mechanisms, and another single common track is used for all of the essentially mirror image right-hand movement mechanisms. Eachtrack 101 has awater drain trough 103, afirst guide channel 105, asecond guide channel 107, adrive cable channel 109 which moves a Bowden-type cable 111, and athird guide channel 113.Sunshades 115 are movable within asunshade channel 117 below and generally parallel to one or more of three sunroof panels. An electric motor actuator 119 (seeFIG. 2 ) is secured to a front of the tub frame below a wind deflector assembly 121 (seeFIG. 13 ).Cable 111 is automatically pushed and pulled byactuator 119 within acable sheath 123. A run-outsheath 125 is also attached to a front corner drain trough 127 (seeFIG. 13 ). - A
middle track insert 131 is attached to track 101 and has acamming slot 133 with a first longitudinally elongatedsection 135 and a second generally diagonally angledsection 137 blending intosecond channel 107 oftrack 101. Afront track insert 139 is also attached to track 101 and has a generallydiagonal camming slot 141 downwardly and rearwardly declining, and blending intofirst channel 105 oftrack 101. -
Front movement mechanism 65 can be observed inFIGS. 13-21 . Afront slide block 151 includes abody 153, roller orrectangular slide feet 155 laterally mounted on each side of the body, acable retainer 156 projecting from a side of the body, acamming section 157 extending from a leading end of the body, ahousing 159 mounted to a top of the body, and a downwardly and rearwardly decliningramp 161 extending from a trailing end of the body.Camming section 157 has a pair of parallel and generally verticallyplanar walls 163 connected at their bottoms by a plate 165. A diagonally elongatedcamming slot 167 upwardly and forwardly inclines frombody 153.Walls 163 are spaced away from each other with a top-accessible gap therebetween to allow passage of a coupled bracket. Atop opening 169 is located in eachslot 167adjacent body 153, with abridge 171 spanning across the slot in a laterally offset manner, to allow insertion of a laterally projectingcam follower pin 173 which thereafter rides alongslots 167.Pin 173 is attached to aprimary front bracket 175 which is mounted to a secondary front bracket, that is in turn, attached to aframe 177 adhered to an interior surface offront sunroof panel 63. -
Housing 159 has a generally inverted-U shape with a predominantly verticalplanar wall 191. A generally vertically elongated andclosed slot 193 is disposed inwall 191 ofhousing 159. A middle of a frontpanel lock pin 195 selectively rides up and down withinslot 193 ofhousing 159, an inboard end ofpin 195 rides fore-and-aft or diagonally within the camming slot ofmiddle track insert 131 and an outboard end ofpin 195 is selectively engagable with its central panel locking hook. -
Front movement mechanism 65 further employs alift arm link 201 that is pivotally attached to the body offront slide block 151 and is pivotally attached tofront bracket 175, by fixed axis pivots 203 and 205, respectively. A guide pin 207 (seeFIG. 19 ) couples liftarm link 201 tocamming slot 141 offront track insert 139. Supplemental panel locks 209 are stationarily attached to track 101 and have a lateral pin which selectively engages a receptacle ofsecondary bracket 176 whenfront sunroof panel 63 is in its closed position. The operation of front movement mechanism can be observed inFIGS. 30-35 whereFIG. 30 represents the closed position,FIG. 31 represents the venting position, andFIG. 34 represents front and central mechanism engagement. - Central movement mechanism 69 is illustrated in
FIGS. 18 , 19, 24A, 24B and 26.Central sunroof panel 67 has aperipheral frame 251 adhered to a bottom surface thereof, with a generally L-shapedbracket 253 having a generally vertical and fore-and-aftelongated wall 255 extending down therefrom. Rollers or slidefeet 257 laterally project fromwall 255 for engagement within third guide channel 113 (seeFIG. 12 ) oftrack 101. Abifurcated hook 259 forwardly projects fromwall 255 and has a diagonallyopen receptacle 261 selectively aligned with diagonalcamming slot section 137 ofcam insert 131. When the front sunroof panel andfront movement mechanism 65 have been partially rearwardly moved to the position shown inFIG. 34 , then pin 195 is downwardly moved withinslot 193 bydiagonal camming slot 137 in order to engage withinreceptacle 261 ofhook 259. This rearward movement offront movement mechanism 65 further causes ramp 161 to upwardly drive lockingpin 281 within a pair of generallyvertical slots 283.Slots 283 are located in a generally inverted-U shapedhousing 285 affixed to an inside surface ofbracket 253. This causes the crosscar elongated lockingpin 281 to rise over anabutment surface 287 of astop 289 which is stationarily attached to track 101. In its closed position,central sunroof 67 is positionally secured by abutment ofpin 281 againstabutment surface 287. An extension spring downwardlybiases pin 281. Furthermore, a slide orroller foot 291 slidably rides within the second guide channel oftrack 101. Thus, disengagement of lockingpin 281 fromstop 289 and engagement ofpin 195 withhook 259 allows central movement mechanism 69 andcentral sunroof panel 67 to be passively driven fore-and-aft byfront movement mechanism 65 andfront sunroof panel 63, for example, from the position shown inFIG. 34 to that shown inFIG. 35 . Moreover, adouble bulb weatherstrip 293 is mounted in a crosscar extendingdrain trough 295 in order to seal against the bottom offrame 251 offront sunroof panel 63. -
Rear sunroof panel 71 and its associatedmovement mechanism 73 are independently driven by a rear electric motor actuator 301 (seeFIG. 2 ) via a Bowden-type cable.Rear movement mechanism 73 can best be observed inFIGS. 22 , 23 and 25-29B.Rear movement mechanism 73 includes a four-bar linkage assembly 303, arear slide block 305 and arear panel carriage 307. These act in concert with a rearpanel carriage lock 309 and arear track insert 311. Four-bar linkage assembly 303 has a generally straight leadinglink 313 and a generally straight trailinglink 315. An upper end of eachlink bracket 317, which is attached to an underside of aframe 318 peripherally adhered torear sunroof panel 71, by fixed axis pivots 319. A lower end of leadinglink 313 is pivotally connected torear panel carriage 307, adjacent laterally extending rollers or slidefeet 331, about a fixed axis pivot. A lower end of trailinglink 315 has a fixedaxis pivot 335 connected to ahook 337 rearwardly projecting fromrear panel carriage 307. Trailinglink 315 further includes acam follower pin 339 laterally projecting from a middle portion thereof.Cam follower pin 339 rides along anangled camming path 341 inrear slide block 305. - A rear
panel locking pin 351 extends in a crosscar direction with a proximal end acting as a cam follower riding in acamming groove 353 inrear track insert 311.Camming groove 353 has a generally fore-and-aft and horizontally elongated rear section and a front diagonal section that is forwardly declining. An opposite distal end of rearpanel locking pin 351 rides within a generally vertical slot 355 (seeFIG. 36 ) ofrear slide block 305. A rearwardlyopen receptacle 357 ofhook 337 is selectively aligned with the diagonal section ofcamming groove 353 ofrear track insert 311 to receive an intermediate section of rearpanel locking pin 351, whereafter the hook and rearpanel carriage lock 309 are secured and locked in a closed position. - An
extension spring 360 runs from ahole 361 in rearpanel carriage lock 309 to apost 363 from rearpanel carriage lock 309 in order to bias the carriage lock down into areceiver 365 stationarily secured to track 101. Aramp 371, shown inFIGS. 38 and 39 , forwardly projecting fromrear slide block 305 operably contacts against and upwardly disengages a trailing end of rearpanel carriage lock 309 fromstationary lock receiver 365 to allow for continued forward movement ofrear sunroof panel 71. The movement ofrear sunroof panel 71 and its associatedrear movement mechanism 73 can be observed with reference toFIGS. 36-40 . In its closed position, the four-bar linkage assembly is upwardly extended and both locking devices are in a locking orientation. However, forward movement ofrear slide block 305 causes four-bar linkage assembly 303 to collapse and further forward movement causes unlocking of thelocking devices rear sunroof panel 71 is moved to its open position beneathcentral sunroof panel 67. - While the multi-panel sunroof has been disclosed, it should be appreciated that other variations fall within the scope of the present invention. For example, two or more central sunroof panels and their associated movement mechanisms may be provided. Furthermore, a central sunroof panel may be actively driven by its own actuator although some of the advantages of the present invention may not be realized. Additionally, it is envisioned that alternate camming, linkages, or track configurations can be employed although various packaging advantages may not be achieved. Alternately, the central sunroof panel can be stationary and immovably affixed to the tracks with brackets, but with the common tracks still being employed. In another alternate embodiment, the rear header panel moves with the rear sunroof panel. It is further envisioned that some of the mechanisms disclosed herein can be used with a single panel sunroof although many of the advantages of the present invention will not be observed. The present invention can also be part of a modularized and preassembled unit including a roof rack, headliner, sun visor assist handles and overhead entertainment console, with a single electrical connection. It is intended by the following claims to cover these and any other departures from the disclosed embodiments which fall within the true spirit of this invention.
