Basically, a vehicle body structure is configured to reduce the rotation of a side roof rail that may occur during a side collision that deforms the center pillar inwardly of the vehicle body. The vehicle body structure basically includes a side rail reinforcement member located in the area where the center pillar is attached to the roof side rail. The reinforcement member can basically be divided into a first side rail reinforcement section that extends in a forward to aft direction along the roof side rail and a second side rail reinforcement section that extends in an inward direction relative to the longitudinal axis of the roof side rail. The second section of the roof side rail overlies a portion of the sliding door pocket structure that is located just rearwardly of the center pillar.
A vehicle upper body structure of the present invention includes: a step part for arranging a slide rail formed on a roof side rail; a pillar that is joined to the roof side rail in the vicinity of a standing wall that constitutes a front end part of the step part; and a roof arch that is joined to the roof side rail together with the pillar in the vicinity of the standing wall.
The present invention provides a joint construction in an upper part of a center pillar, in which a groove part 5 having a substantially U-shaped cross section, which is open upward and extends in the longitudinal direction of a vehicle 1, is provided in a joint portion between a roof panel 2 and a side body outer panel 3 of the vehicle 1, wherein a roof center member 6 is provided under the roof panel 2, and on the other hand, a rail side inner panel 12 and a center pillar reinforce 10 are provided in a center pillar upper portion D; a vehicle inside end part 10a of the center pillar reinforce 10 extends toward the upper inside of the vehicle 1, and is joined to the roof center member 6, the roof panel 2, and the side body outer panel 3 in the groove part 5; and the vehicle inside end part 10a of the center pillar reinforce 10 is provided so as to extend to a vehicle inside end portion 12a of the rail side inner panel 12.
A vehicle body includes a center pillar structure including an outer reinforcement having an outer wall and two side walls defining a channel. Two reinforcements are located within the channel, each rigidly interconnecting the outer wall with a respective one of the sidewalls. A tension panel preferably interconnects the two sidewalls. The center pillar structure is characterized by continuity of strength along its height and increased resistance to vertical compressive loads.
A vehicle roof structure is disclosed that includes a front roof rail, a pair of front roof rail braces and a pair of A-pillars. First ends of the front roof rail braces are fixedly coupled to opposite ends of the front roof rail. The pair of A-pillars each has an inner A-pillar panel. Second ends of the front roof rail braces are bonded to a connection area of a respective one of the inner A-pillar panels such that the opposite ends of the front roof rail are spaced inwardly from the inner A-pillar panels by the front roof rail braces. The front roof rail extends perpendicularly from the A-pillars via the front roof rail braces. Further, each of the inner A-pillar panels has a generally constant overall transverse cross sectional shape across the connection areas of the inner A-pillar panels.
A one-piece B-pillar having a front flange and a rear flange formed on an upper portion of the B-pillar. The front and rear flanges extend forwardly and rearwardly from a trapezoidal section of the B-pillar. An inner concave portion is provided in a lower portion of the B-pillar. The one-piece B-pillar is secured to the outer and upper surfaces of a roof rail and to the outer surface of a rocker to provide side impact strength. The B-pillar is hydroformed in one-piece to provide superior strength for roof crush performance. The tubular portion of the B-pillar is partially collapsed to form a trapezoidal section in the upper portion of the B-pillar.
