Abstract
A body upper structure includes a roof side-rail (1) and a center pillar (9) having a pillar outer member (10). The roof side-rail (1) has a vertical rib (7) bridging between an upper wall and a lower wall. The pillar outer member (10) has a plurality of vertical ribs (13). In operation, at a vehicle collision, the vertical rib (7) of the roof side-rail (1) acts to receive a downward bending load, in the form of a buckling load in the up-and-down direction while exhibiting a high resistance against the bending load. Subsequently, the downward load is accepted by a shoulder part (12) and the vertical ribs (13) of the pillar outer member (10), in the axial direction of the center pillar (9) and transmitted in dispersion to the whole center pillar (9) effectively.
Claims8
A body upper structure for a vehicle, comprising:
- a roof side-rail which is formed to have a closed cross section and also provided with a vertical rib bridging between an upper wall and a lower wall both forming the roof side-rail;
- and
- a center pillar united with the roof side-rail, the center pillar having a pillar outer member and a shoulder part formed on an upper end of the pillar outer member so as to fit a successive corner defined between the lower wall and an outer wall forming the roof side-rail thereby to support the roof side-rail;
- wherein the pillar outer member is provided, on an interior side thereof with a plurality of vertical ribs at an interval in a fore-and-aft direction of the vehicle, the vertical ribs extending from a base of the shoulder part downward while respective upper ends of the vertical ribs are abutting on the lower wall of the roof side-rail;
- and
- wherein the vertical ribs are formed to project inwardly in a width direction of the vehicle, up to a position where, in a vertical direction of the vehicle, the upper ends of the vertical ribs substantially overlap and align with the vertical rib of the roof side-rail.
