Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a vehicle body structure. More specifically, the present invention relates to a vehicle body structure of a vehicle that is equipped with a sliding door. 2. Background Information Various constructions of vehicles with sliding doors are known. In general, the sliding door has a slider or roller that slides along an upper guide rail installed on the roof side frame and a lower guide rail mounted on the side sill. A center pillar is usually located at the forward end of the sliding door. This center pillar connects the roof side frame to the side sill of the vehicle body structure. The side of the vehicle body structure is constructed in a manner to minimize excessive deformation in order to protect the occupants in the event of a side collision. In other words, the side of the vehicle body structure is constructed with sufficient rigidity so that the occupants are protected. For example, a vehicle body structure having a sliding door is disclosed in U.S. patent Publication No. 2003/0085593 in which the roof side frame is reinforced. The reinforcement member used in the vehicle body structure disclosed in this publication is disposed along the axis of the roof side frame. 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 body structure. 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 It has been discovered that during a side collision, the center pillar may be deformed inwardly of the vehicle body such that a force is applied to the side roof rail that may rotate the side roof rail. In other words, when a side collision occurs, an inwardly directed force is often applied to the center pillar that may cause the roof side frame to rotate about a front to aft axis of the vehicle body structure. In the above-mentioned publication, the reinforcement member is disposed along the axis of the roof side frame. Thus, this reinforcement does not effectively minimize location rotation of the roof side frame. It has been discovered that it is desirable to distribute the load acting on the center pillar along the entire side rail or as much as reasonably possible. By distributing the load acting on the center pillar along the side rail, it is possible to minimize the local deformation. Thus, the integrity of the side of the vehicle can be improved because the loading of the side rail from the impact force on the center pillar is transferred primarily as a translational load instead of a rotational load. In view of the above, one object of the present invention is to provide a vehicle body structure that reduces the rotation of the side roof rail that may occur during a side collision that deforms the center pillar inwardly of the vehicle body. To achieve this objective, a vehicle body structure is provided that comprises a center pillar, a roof side rail and a reinforcement member. The center pillar extends in a generally vertical direction of the vehicle body structure. The roof side rail is fixedly coupled to the center pillar. The roof side rail includes a generally longitudinal axis extending in a front to aft direction of the vehicle body structure, a sliding door pocket structure projecting inwardly of the longitudinal axis of the roof side rail to form a front roller receiving recess for a sliding door. The reinforcement member is coupled to the roof side rail. The reinforcement member has a first section extending along the longitudinal axis of the roof side rail to one side of the center pillar, and a second section extending inwardly from the first section at a predetermined angle such that the second section overlies the sliding door pocket structure. 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.

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 FIG. 1, a vehicle 10 with a vehicle body structure 12 is illustrated in accordance with a first embodiment of the present invention. The vehicle 10 further includes a pair of sliding doors 14 (only one shown) mounted on the vehicle body structure 12 in accordance with the present invention. The sliding doors 14 are slideably mounted on the vehicle body structure 12 via three upper rollers and three lower rollers. The constructions of the sliding doors 14 and the attachment arrangements of the sliding doors 14 are relatively conventional and will not be discussed or illustrated in detail herein. Rather, it will be apparent to those skilled in the art from this disclosure that the precise construction of the sliding doors 14 and their roller structures are not critical to the present invention. Moreover, it will be apparent to those skilled in the art from this disclosure that each of the sliding doors 14 is supported on the vehicle body structure 12 in the same manner, except that they are mirror images of each other. Therefore, only the left side of the vehicle body structure 12 will be discussed and illustrated in detail herein. The vehicle body structure 12 includes various structural support members and body panels that define the cabin of the vehicle. These parts are all fixedly coupled together utilizing conventional automobile manufacturing techniques to form a rigid body. For the sake of brevity, only those body structures that are needed to understand the present invention will be discussed and illustrated herein. As seen in FIG. 3, the vehicle body structure 12 of the present invention basically includes a pair of roof side rails 20, a pair of center pillars 22, and a plurality of cross rails 24 a, 24 b and 24 c. Preferably, each of these portions of the vehicle body structure 12 are constructed of a rigid material such as sheet metal that is bonded (e.g., welded or cemented) together utilizing conventional automobile manufacturing techniques. Basically, the vehicle body structure 12 is configured and arranged to reduce the rotation of the side roof rails 20 that may occur during a side collision that deforms one of the center pillars 22 inwardly of the vehicle body by using reinforcing the side roof rails 20 as explained below. As seen in FIG. 4, the roof side rail 20 is constructed of several pieces. It will be apparent to those skilled in the art from this disclosure that the number of pieces and the locations of the joints of the pieces are not limited to the embodiment illustrated herein. In other words, the number of pieces and the locations of the joints for the roof side rail 20 can be changed without departing from the scope of the present invention. Basically, the roof side rail 20 has a front side rail portion 30, a rear side rail portion 32 and a side rail reinforcement member 34. The rear side rail portion 32 has a sliding door pocket structure 36 integrally formed therewith as discussed below in more detail. The roof side rail 20 has a center longitudinal axis A that extends in a front to aft direction of the vehicle body structure 12. In the illustrated embodiment, the center longitudinal axis A is a curved axis that follows the contour of the roof side rail 20. The center pillar 22 is attached to the roof side rail 20 at the intersection of the front side rail portion 30 and the rear side rail portion 32 such that the sliding door pocket structure 36 is disposed rearwardly of the center vertical axes B of the center pillar 22. Preferably, a part of the center pillar 22 also forms a part of the roof side rails 20 as discussed below. The cross rail 24 c is preferably connected to the roof side rails 20 such that the center of the cross rail 24 c is substantially aligned with the center vertical axis B of the center pillars 22. Preferably, the front side rail portion 30 includes an inner side rail part 30 a and an outer side rail part 30 b. The inner and outer side rail parts 30 a and 30 b are secured along their longitudinally extending edges to form a substantially closed tubular cross section of the front side rail portion 30 of the roof side rail 20. The front side rail portion 30 basically corresponds to the portion of the roof side rail 20 that forms a side support for the windshield and an upper support for the front side door opening of the vehicle body structure 12. Preferably, the inner side rail part 30 a and the outer side rail part 30 b are sheet metal parts that are bonded, e.g., welded, together. The rearward end of the inner side rail part 30 a is bonded, e.g., welded, to the rear side rail portion 32 and the center pillar 22. The outer side rail part 30 b has its rearward end bonded, e.g., welded, to the center pillar 22. s seen in FIGS. 9-11, the roof side rail 20 has an exterior sheet metal layer 38 that forms the exterior surface of the vehicle. Since the exterior surface of the vehicle 10, including but not limited to the exterior sheet metal layer 38, is not important to the present invention, the exterior surface of the vehicle 10 will not be discussed or illustrated herein. Moreover, it will be apparent to those skilled in the art from this disclosure that a separate exterior layer is not required, but rather the parts of the vehicle 10 discussed herein can be configured to form the exterior layer of the vehicle 10. As seen in FIGS. 10 and 11, the side rail reinforcement member 34 is partially located in between the inner and outer side rail parts 30 a and 30 b. Preferably, the side rail reinforcement member 34 is secured to at least one of the pairs of the longitudinal edges of the inner and outer side rail parts 30 a and 30 b, as discussed below. In the illustrated embodiment, the cross-sectional profile of the side rail reinforcement member 34 and the outer side rail part 30 b are substantially similar such that the side rail reinforcement member 34 together with the front side rail portion 30 form a tubular portion extending in a front to aft direction of the vehicle body structure 12. As seen in FIG. 3, the rear side rail portion 32 forms the upper support for the sliding door 14. Thus, the rear side rail portion 32 has a substantially open cross section that faces in an outboard direction of the vehicle body structure 12. The forward end of the rear side rail portion 32 is preferably fixedly coupled, e.g., welded, to the rearward end of the inner side rail part 30 a of the front side rail portion 30, as seen in FIG. 12.

Basically, as seen in FIG. 4, the rear side rail portion 32 includes a main support part 32 a, a roller rail 32 b, a pocket trim member 32 c and an upper plate section or member 32 d. Of course, the rear side rail portion 32 also includes other trim parts (not shown) and the outer sheet metal panel portion (not shown) to finish the appearance of the rear side rail portion 32. In the illustrated embodiment, the main support part 32 is a contoured structural part that is formed from sheet metal utilizing conventional automobile manufacturing techniques. The sliding door pocket structure 36 is integrated within the main support part 32 a as a one-piece, unitary member. Preferably, the sliding door pocket structure 36 is spaced rearwardly from the free end of the main support part 30 a of the rear side rail portion 32. The pocket trim member 32 c is attached to the main support part 32 a utilizing conventional fastening structure such that the pocket trim member 32 c substantially overlie the exteriorly facing surfaces of the sliding door pocket structure 36. The roller rail 32 b is mounted to overlie the exterior surface of the main support part 32 a and a portion of the sliding door pocket structure 36 after the pocket trim member 32 b has been installed. The upper plate member 32 d is preferably constructed of a rigid material such as sheet metal. The upper plate member 32 d is rigidly attached to the upper edge of the main support part 32 a such that it overlies the sliding door pocket structure 36. Thus, the upper plate member 32 d adds rigidly to the upper edge of the sliding door pocket structure 36. As best seen in FIGS. 8 and 12-16, the sliding door pocket structure 36 basically has a base section 36 a and an arch-shaped wall 36 b that forms a roller pocket for the front roller of the roller structure of the sliding door 14. The arch-shaped wall 36 b preferably extends upwardly in a substantially perpendicular direction from the base section 36 a. The arch-shaped wall 36 b is concaved such that its exteriorly facing surface faces in an outboard direction of the vehicle body structure 12. The arch-shaped wall 36 b has its concaved exterior surface located inwardly of the main longitudinal axis A of the roof side rail 20. The forward end of the sliding door pocket structure 36 and the rearward end of the side rail reinforcement member 34 are secured together in an overlapping manner, as best seen in FIGS. 15 and 16. In other words, the overlapping area of the side rail reinforcement member 34 and the sliding door pocket structure 36 lies inboard of the inner edge of the portion of the side rail 20 that is located in front of the center pillar 22. Preferably, the overlapping area of the side rail reinforcement member 34 and the sliding door pocket structure 36 lies in at least two generally perpendicular planes. In any event, the overlapping area of the side rail reinforcement member 34 and the sliding door pocket structure 36 at least preferably has a three dimensional cross section that resist deformation. As seen in FIGS. 4-7, the center pillar 22 preferably includes an inner center pillar part 22 a and an outer center pillar part 22 b that are fixedly coupled together, e.g., welded, to form an integrated unit having a hollow interior. Preferably, the inner and outer center pillar parts 22 a and 22 b are formed of a rigid material such as sheet metal that are configured and arranged utilizing conventional automotive manufacturing techniques. The center pillar 22 has a minimum width section C defining a minimum front to aft width of the center pillar 22 that is substantially located in a front to aft direction that is near the connection between the front side rail portion 30 and the rear side rail portion 32. Stated differently, the minimum width section C of the center pillar 22 is located such that a majority of the minimum front to aft width section C of the center pillar 22 overlaps with the side rail reinforcement member 34 in the front to aft direction of the vehicle body structure 12. Preferably, the leading edge of the minimum width section C is substantially aligned with the joint formed between the inner side rail part 30 a and the main support part 32 a. The side rail reinforcement member 34 extends in a front to aft location above the center pillar 22 such that a the side rail reinforcement member 34 is at least partially located in front of and partially rearwardly of the minimum front to aft width section of the center pillar 22. As best seen in FIGS. 7 and 13, the inner center pillar part 22 a has an upper end 40 that flairs outwardly in the forward and rearward directions of the vehicle body structure 12. The upper end 40 of the inner center pillar part 22 a is coupled to both the front side rail portion 30 and the main support part 32 a. The center vertical axis B of the center pillar 22 that bisects the minimum width section C of the center pillar 22 is preferably substantially aligned with the leading edge of the sliding door pocket structure 36. As best seen in FIGS. 5 and 17, the outer center pillar part 22 b has an upper end 42 that forms a part of the front side rail portion 30. In other words, the upper end section 42 of the outer center pillar part 22 b extends forwardly from the center pillar 22 and has a cross-sectional profile that substantially corresponds to the outer side rail part 30 b. The upper end section 42 overlies a portion of the side rail reinforcement member 34 as best seen in FIG. 17. Turning now to FIGS. 18-21, the side rail reinforcement member 34 is preferably a rigid member such as a contoured sheet metal member that is constructed utilizing conventional automobile manufacturing techniques. Basically, the side rail reinforcement member 34 is a one-piece, unitary member that can be effectively divided into a first side rail reinforcement section 34a and a second side rail reinforcement section 34 b (indicated by the shaded area in FIGS. 18-21). Basically, the first side rail reinforcement section 34 a is defined by the portion of the side rail reinforcement member 34 that extends substantially in a longitudinal direction of the vehicle, while the second side rail reinforcement section 34 b is that portion of the side rail reinforcement member 34 that projects inwardly relative to the front side rail portion 30. Preferably, as seen in FIGS. 10 and 11, the side rail reinforcement section 34 a includes a first wall 50 and a second wall 52 that form a substantially inverted L-shaped or inverted V-shaped cross-sectional profile. Preferably, the free end of the second wall 52 has mounting tabs 54 that are sandwiched between the upper longitudinal edges of the inner side rail part 30 a and the outer side rail part 30 b such that they are rigidly connected together. The first wall 50 also preferably has a mounting portion 56 that is bonded to at least the inner side rail part 30 a. Preferably, the interiorly facing surfaces of the first and second walls 50 and 52 of the side rail reinforcement section 34 a are arranged such that the side rail reinforcement member 34 is concaved relative to the longitudinal axis of the roof side rail 20. As seen in FIG. 8, the first side rail reinforcement section 34 a preferably extends in a forward to aft direction of the vehicle body structure 12 along the longitudinal axis of the roof side rail 20 such that a portion of the side rail reinforcement section 34 a is located on the front side and the rear side of the minimum width section C of the center pillar 22. The side rail reinforcement section 34 b is preferably located at the rear end of the first side rail reinforcement section 34 a and projects inwardly relative to the roof side rail 20. The second side rail reinforcement section 34 b also preferably has at least a substantially inverted L-shaped or inverted V-shaped cross-sectional profile that is formed by a first wall 60 and a second wall 62. Moreover, the second side rail reinforcement section 34 b preferably has an additional mounting tab 64 that extends outwardly from the bottom side of the first wall 60 that is opposite the second wall 62. Thus, the overall cross-sectional profile of the second side rail reinforcement section 34 b is substantially Z-shaped. Basically, the first walls 50 and 60 of the first and second side rail reinforcement sections 34 a and 34 b form a continuous side wall structure, while the second walls 52 and 62 of the first and second side rail reinforcement sections 34 a and 34 b form a second continuous side wall structure that is arranged substantially perpendicularly. Preferably, the first wall 62 overlies in an overlapping manner with the arch-shaped wall 36 b of the sliding door pocket structure 36, while the mounting tab 64 substantially overlies in an overlapping manner the base section 36 a of the sliding door pocket structure 36. Accordingly, the reinforcement member 34 provides reinforcement in a longitudinal direction by the first side rail reinforcement section 34 a and a transverse reinforcement by the second side rail reinforcement section 34 overlying the base section 36 a and the arch-shaped wall 36 b of the sliding door pocket structure 36. Preferably, the second side rail reinforcement section 34 b is located substantially at the center area of the center pillar 22 such that when an inwardly directed force is applied to the center pillar 22 such as during a side collision, the side rail reinforcement member 34 minimizes the rotation of the roof side rail 20 about its longitudinal axis. Thus, a more rigid structure is attained for the roof side rail 20. As used herein, the following directional terms �forward, rearward, above, downward, vertical, horizontal, below and transverse� as well as any other similar directional terms refer to those directions of a vehicle equipped with the present invention. Accordingly, these terms, as utilized to describe the present invention should be interpreted relative to a vehicle equipped with the present invention. Moreover, terms that are expressed as �means-plus function� in the claims should include any structure that can be utilized to carry out the function of that part of the present invention. Also, terms of degree such as �substantially�, �about� and �approximately� as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. For example, these terms can be construed as including a deviation of at least �5% of the modified term if this deviation would not negate the meaning of the word it modifies.
