BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to reinforcement of a vehicle body structure. More specifically, the present invention relates to a vehicle support structure that includes a sunroof.
2. Background Information
A variety of vehicle body constructions are broadly classified into two categories: (1) a unibody or unitized construction in which a self-supporting body has a plurality of rigidity members integrated therewith; and (2) a frame on chassis or framed construction in which a separate body is connected to a structural framework. The framed construction is mainly applied to commercial vehicles and trucks. Most passenger vehicles utilize a conventional unitized (self-supporting) vehicle body that is built from sheet metal components onto which body panels are welded. Generally, the structural configurations of these unitized vehicle bodies are continuously being improved for a variety of reasons. For instance, these unitized vehicle bodies have been developed so as to simplify the assembly process, and thereby reducing manufacturing costs. Moreover, these unitized vehicle bodies have been extensively redesigned over the years to improve the strength and rigidity of the vehicle in the event of impact from the side.
In the case of vehicle roof structures, a center cross member is typically included as part of the roof structures beneath a roof panel of the vehicle to provide lateral support as well as to support the roof panel. The center cross member is often positioned at a point coinciding with the B-pillars of the roof support structure. The B-pillars are typically upright support structures supporting the roof and doors at a location between front and rear side windows of the vehicle. However, when a sunroof is included in the vehicle roof support structure, the center cross member is often repositioned such that the center cross member is longitudinally offset from the B-pillars. Specifically, instead of joining side rail members at a point coinciding with the B-pillars, the center cross member joins the side rail members rearward from the B-pillars. Thus, the transfer of load across the roof during side impact can be less effective for sunroof vehicles.
In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved vehicle support structure for roof structures with a sunroof. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
SUMMARY OF THE INVENTION
One object of the present invention is to provide a vehicle support structure that includes reinforcement features when the center cross member is offset from the center pillar.
Another object of the present invention is to provide a vehicle support structure that includes a sunroof and reinforcement features in regions proximate the sunroof to increase rigidity of the vehicle support structure.
In accordance with one aspect of the present invention, a vehicle body structure includes a generally horizontal roof panel having a side edge portion, a body side outer panel, a vertically extending center pillar outer member, a longitudinally extending roof side rail outer member, a longitudinally extending roof side rail inner member, and a longitudinally extending reinforcement member. The body side outer panel is fixedly coupled to the roof panel and extends generally downward from the side edge portion of the roof panel to form a corner area. The vertically extending center pillar outer member includes a generally vertical extending pillar portion and a generally horizontal extending upper pillar portion located at an upper end of the vertical extending pillar portion in the corner area. The upper pillar portion has a generally overall U-shaped transverse cross section with an upper end section and a lower end section. The longitudinally extending roof side rail outer member has a generally overall U-shaped transverse cross section positioned at the corner area. The roof side rail outer member has a first side rail outer portion fixedly coupled to the upper end section of the upper pillar portion and a second side rail outer portion fixedly coupled to the lower end section of the upper pillar portion. The longitudinally extending roof side rail inner member has a first side rail inner portion fixedly coupled to the first side rail outer portion and a second side rail inner portion fixedly coupled to the second side rail outer portion and the lower end section of the upper pillar portion. The longitudinally extending reinforcement member has a generally overall U-shaped cross section that includes a first edge portion connected to the first side rail outer portion and a second edge portion connected to the second side rail outer portion. The reinforcement member extends generally perpendicular to the center pillar outer member.
These and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Selected embodiments of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the present invention are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Referring initially to FIGS. 1 and 2, a vehicle 10 is illustrated that includes a vehicle body structure 12 in accordance with a preferred embodiment of the present invention. As shown in FIG. 2, the vehicle body structure 12 includes structural reinforcements in regions adjacent to a sunroof support structure 14, as described in greater detail in below.
With specific reference to FIGS. 2, 3 and 4, a general description of the vehicle body structure 12 is now provided. It should be understood from the drawings and description herein that various portions and components of the vehicle body structure 12 have been omitted for the sake of brevity and clarity. For example, floor, trunk, firewall, windshield, rear window, doors and engine compartment related portions, among others of the vehicle body structure 12 have been intentionally omitted in order to focus on mainly those elements and components of vehicle body structure 12 related to or peripheral to the present invention.
The vehicle body structure 12 basically includes (among other elements and portions) a generally horizontal roof panel 16 (shown in FIGS. 2 and 4), a pair of body side outer panels 18, a pair of roof side rail outer members 20, a pair of roof side rail inner members 22 (FIGS. 2 and 4), a pair of center pillar structures 24, a pair of reinforcement members 26, a center cross member 28, a pair of cross bows 30 and 32, and a pair of gussets 34 (FIG. 4). Each portion of the vehicle body structure 12 is preferably made of a metallic material, but can alternatively be made of other suitable materials with similar strength and rigidity. The center cross member 28 is a generally horizontally extending member and the center pillar structures 24 are generally vertically extending. Each center pillar structure 24 defines a generally vertical central axis. Moreover, the center cross member 28 is longitudinally offset from the central axis of the center pillar structures 24 that constitutes part of the so called B-pillars. More specifically, the center cross member 28 is longitudinally rearward from the B-pillars.
Since the various elements on either side of vehicle body structure 12 are generally symmetrical to one another, only elements on one side of the vehicle body structure 12 are described herein below. However it should be understood from the drawings and the description herein that description of an element or portion on one side of the vehicle body structure 12 applies to both sides. For instance, the body side outer panels 18 are generally symmetrical to one another and generally include common features portions. Therefore, a description of only one of the body side outer panels 18 is included herein below. Similarly only one roof side rail outer member 20, one roof side rail inner member 22, one pillar structure 24, one reinforcement member 26 and one gusset 34 are described herein below with description of one applying to both sides of the vehicle body structure 12.
Still with reference to FIGS. 2, 3 and 4, a description of the sunroof support structure 14 is now provided. The sunroof support structure 14 basically includes a pair of tracks 35, a sunroof cross member 36, an operating mechanism (not shown), a rectangular framing member 37, a sliding sunroof panel 38 and attachment gussets 39. The sunroof support structure 14 is a conventional structure that is configured to allow movement of the sliding sunroof panel 38 along the tracks 35 such that the sliding sunroof panel 38 can move in and out of the framing member 37 between a closed orientation and an open orientation. The attachment gussets 39 are curved or angled bracket-like portions that can include either bolt holes or welding surfaces for fixed attachment to the vehicle body structure 12. Specifically, the attachment gussets 39 can be fixedly attached to the roof side rail inner member 22.
With reference now to FIGS. 2 and 4, a description of the roof panel 16 is now provided.

With the sunroof support structure 14 installed in the vehicle body structure 12, the framing member 37 is generally aligned with and surrounds the sunroof opening 44 of the roof panel 16. The sliding sunroof panel 38 and sunroof support structure 14 is configured such that the sliding sunroof panel 38 fits snugly in the sunroof opening 44 of the roof panel 16 in the closed orientation and moves down and back along the tracks 35 away from the sunroof opening 44 in a conventional manner to the open orientation.
As shown in FIG. 4, the body side outer panel 18 basically includes a sill section 46 (optional), a plurality of pillar sections 48, 50 and 52, an upper rail section 54 and an upper attachment flange 56. The pillar section 48 corresponds generally to a conventional A-pillar of the vehicle 10. The pillar section 50 generally corresponds to a conventional B-pillar of the vehicle 10. More specifically, the pillar structure 24 and the pillar section 50 of the body side outer panel 18 generally define the B-pillar of the vehicle 10. Similarly, the pillar section 52 corresponds generally to a C-pillar of the vehicle 10.
As shown in FIG. 8, the roof panel 16 and the body side outer panel 18 are fixedly attached to one another thereby defining a corner area in the region of their intersection. More specifically, the side edge portion 40 of the roof panel 16 is welded or otherwise bonded to the upper attachment flange 56 of the body side outer panel 18. Since the roof panel 16 is generally horizontal and the body side outer panel 18 extends generally downward, the corner area is formed. FIGS. 5, 6, 7 and 8 show the various connections of the vehicle body structure 12 within the corner area, as described in greater detail below. However, FIGS. 5, 6 and 7 also show the corner area from the inside of the vehicle 10 but with the roof panel 16 and the body side outer panel 18 removed for greater clarity.

The roof side rail inner member 22 basically includes a first side rail inner portion 70, a second side rail inner portion 72 and a mid side rail inner portion 74. The second side rail inner portion 72 and the mid side rail inner portion 74 of the roof side rail inner member 22 are generally flat portions, with the first side rail inner portion 70 being angularly offset from the second side rail inner portion 72 and the mid side rail inner portion 74. Further, the mid side rail inner portion 74 extends generally parallel to the second side rail inner portion 72, as shown in FIG. 17. However, the mid side rail inner portion 74 is slightly offset from the second side rail inner portion 72 as shown in cross-section in FIG. 17. The mid side rail inner portion 74 includes threaded fastener apertures 76. As indicated in FIG. 3, the roof side rail inner member 22 has a length L2 and extends along the side of the vehicle body structure 12 from an area approximately in the middle of the sunroof opening 44 to an area rearward of the bows 30 and 32.
As indicated in FIG. 3, the roof side rail outer member 20 and the roof side rail inner member 22 overlap one another in a longitudinal direction of the vehicle 10. Specifically, the roof side rail outer member 20 extends from a point forward from the roof side rail inner member 22 and the roof side rail inner member 22 extends rearward beyond the end of the roof side rail outer member 20. An indication of the overlapping regions of the roof side rail outer member 20 and the roof side rail inner member 22 is indicated by the overlapping indication of their respective lengths L1 and L2. In their common overlapping regions, the roof side rail outer member 20 and the roof side rail inner member 22 are welded or otherwise bonded to one another. As shown in FIGS. 8 and 9, the first side rail outer portion 60 and the first side rail inner portion 70 are welded or otherwise bonded together along their entire overlapping length. Similarly, the third side rail outer portion 67 and the second side rail inner portion 72 are welded or otherwise bonded together to form a hollow beam that provides strength and rigidity to the corner area defined between the roof panel 16 and the body side outer panel 18. As shown in FIGS. 8 and 9, the side edge portion 40 of the roof panel 16, the upper attachment flange 56 of the body side outer panel 18, the first side rail outer portion 60 of the roof side rail outer member 20 and the first side rail inner portion 70 of the roof side rail inner member 22 are all respectively overlap one and other and are welded or otherwise bonded together.
It should be understood from the drawings and the description herein that forward and rearward ends of the roof side rail outer member 20 and the roof side rail inner member 22 are fixedly attached to conventional structural elements of the vehicle 10 that are not depicted or described for the sake of brevity.
With specific reference to FIGS. 4, 12, 18 and 19, the pillar structure 24 is now described. The pillar structure 24 is a hollow column having a closed transverse cross-section as shown in FIG. 21.

The pillar structure 24 basically includes a center pillar inner panel 80 and a center pillar outer panel 82.
As shown in FIGS. 18, 19 and 21, the center pillar inner panel 80 is a vertically extending portion of the pillar structure 24 basically includes a central section 84, side flanges 86, an inner panel upper end 88 and an inner panel lower end 89. The central section 84 is offset from the side flanges 86 thereby forming a generally overall U-shape as viewed in cross section, as shown in FIG. 21. Both the central section 84 and the side flanges 86 are shaped with a slight contour in accordance with the shape and contours of the vehicle 10. The inner panel upper end 88 is fixedly attached, welded or otherwise bonded to the roof side rail inner member 22, as shown in FIGS. 5, 6, 7, 9 and 11.
The center pillar outer panel 82 of the pillar structure 24 is now described with specific reference to FIG. 12. The outer panel 82 of the pillar structure 24 basically includes a generally horizontal extending upper pillar portion 90, a lower end section 92 and a generally vertical extending pillar portion formed by a pair of side flanges 94 and a mid section 95. As shown in FIGS. 8 through 11, the upper pillar portion 90 basically includes a first flange section 96, a second flange section 98, a mid-flange section 100 and a flange 102. The first flange section 96, the second flange section 98 and the mid-flange section 100 extend generally horizontally in the corner area such that upper pillar portion 90 has a generally overall U-shaped when viewed cross section as shown in FIGS. 8, 9 and 10. The lower end section 92 is welded to the sill portion 46 of the body side outer panel 18. Both the side flanges 94 and the mid section 95 are shaped with a slight contour in accordance with the shape and contours of the vehicle 10 complimenting the overall shape of the side flanges 86 and the mid section 86 of the center pillar inner panel 80 of vehicle 10 and its associated design features. The side flanges 94 and the mid section 95 extend generally vertically and define a generally overall U-shape in cross-section, as shown in FIG. 21. The side flanges 86 of the inner panel 80 are bonded (for example, welded) to the side flanges 94 of the outer panel 82 thereby forming a closed cross-section, as shown in FIG. 21. Forming the pillar structure 24 with the center pillar inner and outer panels 80 and 82 provides a strong hollow structure to support the roof panel 16 and supporting structure, thereby minimizing deformation resulting from a side impact.
With specific reference to FIGS. 8, 9 and 10, a description is now provided of the fixed coupling between the upper pillar portion 90 of the center pillar outer panel 82 and the roof side rail outer member 20. Specifically as shown in FIGS. 8 and 9, a section of the second side rail outer portion 62 of the roof side rail outer member 20 is welded or otherwise bonded to the first flange section 96 of the center pillar outer panel 82. However as shown in FIG. 10, in the region of the gusset 34 a gap is defined between the second side rail outer portion 62 of the roof side rail outer member 20 and the first flange section 96 of the center pillar outer panel 82.
As shown in FIG. 10, in the region of the gusset 34, a section of the mid portion 64 of the roof side rail outer member 20 is welded or otherwise bonded to the mid-flange section 100 of the center pillar outer panel 82. However as shown in FIGS. 8 and 9, the remainder of the mid portion 64 of the roof side rail outer member 20 is spaced apart from the mid-flange section 100 of the center pillar outer panel 82.
As shown in FIGS. 8, 9 and 10, the first side offset rail outer portion 65 is spaced apart from the second flange section 98 of the center pillar outer panel 82, but the second offset portion 66 is welded or otherwise bonded to the second flange section 98 of the center pillar outer panel 82. Further, the third side rail outer portion 67 is welded to or otherwise bonded to the flange 102 of the center pillar outer panel 82.

As shown in FIGS. 14 and 15, the reinforcement member 26 basically includes a first reinforcement member flange 103, a reinforcement member mid portion 104, an reinforcement member offset portion 106 and a second reinforcement member flange 108. The reinforcement member 26 is generally divided into several longitudinally extending sections, a forward section S1, a tapered section S2, a mid-section S3 and a rearward section S4. The first reinforcement member flange 103, the reinforcement member mid portion 104, the reinforcement member offset portion 106 and the second reinforcement member flange 108 extend throughout each of the sections S1, S2, S3 and S4. As shown in FIG. 14, the mid-section S3 has a smaller overall profile than the forward section S1. More specifically, in the forward section S1, the distance between the first reinforcement member flange 103 and the second reinforcement member flange 108 is greater than the distance between the first reinforcement member flange 103 and the second reinforcement member flange 108 in the mid-section S3. The mid-section S3 of the reinforcement member 26 is disposed proximate the upper pillar portion 90 of the center pillar outer panel 82. The first reinforcement member flange 103 and the second reinforcement member flange 108 are each further formed with a plurality of longitudinally spaced apart embossments E. The embossments E define connection points or weld points between the first reinforcement member flange 103 and the second side rail outer portion 62, and the second reinforcement member flange 108 and the second offset portion 66 of the roof side rail outer member 20. The embossments E create a clearance between the majority of the roof side rail outer member 20 and the reinforcement member 26.
As shown in FIGS. 8 and 9, the first reinforcement member flange 103 is welded to or otherwise bonded to the second side rail outer portion 62. However as shown in FIG. 10, in the region of the gusset 34, the first reinforcement member flange 103 is spaced apart from the second side rail outer portion 62.
