2. The B-pillar according to claim 1 , wherein the fiber composite component is formed as an integral component.
3. The B-pillar according to claim 1 , wherein the fiber composite component extends across at least 0.25 times a total length of the B-pillar.
4. The B-pillar according to claim 1 , wherein the upper metal portion comprises an upper end edge, and the lower metal portion comprises a lower end edge, wherein the fiber composite component extends with an upper end region across the upper end edge into the upper region for force introduction and extends with a lower end region across the lower end edge into the lower region for force introduction.
5. The B-pillar according to claim 4 , wherein a distance between the upper end edge and the lower end edge is at least 25% and at most 95% of the total length of the B-pillar.
6. The B-pillar according to claim 1 , wherein at least one of a lower end of the fiber composite component is spaced from a lower end of the B-pillar at a distance of at least 10 centimeters (cm) or an upper end of the fiber composite component is spaced from an upper end of the B-pillar at a distance of at least 5 cm.
7. The B-pillar according to claim 1 , wherein the upper metal portion comprises, at least partially, at least one lateral joining flange for connecting components adjacent to the B-pillar to the B-pillar, wherein the at least one lateral joining flange laterally projects beyond the fiber composite component.
8. The B-pillar according to claim 1 , wherein the lower metal portion comprises, at least partially, at least one lateral joining flange for connecting components adjacent to the B-pillar to the B-pillar, wherein the at least one lateral joining flange laterally projects beyond the fiber composite component.
9. The B-pillar according to claim 1 , wherein the upper metal portion and the lower metal portion comprise, at least partially, at least one lateral joining flange for connecting components adjacent to the B-pillar to the B-pillar, wherein the at least one lateral joining flange laterally projects beyond the fiber composite component.
10. The B-pillar according to claim 1 , wherein
the upper metal portion and the lower metal portion are formed by separate sheet metal formed parts which are spaced from each other; and
the upper metal portion and the lower metal portion are joined to one another via the fiber composite component.
11. The B-pillar according to claim 4 , further comprising
a sheet metal formed part extending along the longitudinal axis of the B-pillar and comprising the upper metal portion and the lower metal portion, wherein between the upper end edge of the upper region for force introduction and the lower end edge of the lower region for force introduction, the sheet metal formed part comprises at least one recess which is at least partially filled by the fiber composite component.
12. The B-pillar according to claim 1 , wherein between the upper region for force introduction and the lower region for force introduction, the B-pillar is at least partially U-shaped such that a cavity is formed on a vehicle interior side of the B-pillar for receiving vehicle add-on parts.
13. The B-pillar according to claim 1 , further comprising at least one metallic reinforcing insert being embedded into the fiber composite component for local reinforcement of the B-pillar.
14. The B-pillar according to claim 1 , wherein at least one of the upper metal portion or the lower metal portion comprises a variable wall thickness over the length of the B-pillar.
15. The B-pillar according to claim 1 , wherein the upper metal portion comprises a variable wall thickness over the length of the B-pillar.
16. The B-pillar according to claim 1 , wherein the lower metal portion comprises a variable wall thickness over the length of the B-pillar.
17. A motor vehicle body comprising two B-pillars, wherein the two B-pillars each extend along a longitudinal axis (X) and comprise:
an upper metal portion for connecting the respective B-pillar to a roof area of the motor vehicle body and a lower metal portion for connecting the respective B-pillar to a sill area of the motor vehicle body; and
a fiber composite component comprising fibers and a plastic matrix;
wherein the upper metal portion comprises an upper region for force introduction, and the lower metal portion comprises a lower region for force introduction axially spaced from the upper region for force introduction, the upper region for force introduction and the lower region for force introduction being embedded into the fiber composite component.
