  • Such a known from DE 102 32 320 A1 B-pillar comprises an outer door pillar element in the form of a sheet metal shell, which is also commonly referred to as a strike plate and is assembled and joined with an inner door skin element to a hollow pillar.
  • a reinforcing element is arranged, which connects a laterally corresponding Soschweiler with a roof frame arranged above these.
  • Reinforcing element in the form of a tube which is connected by inert gas welding or spot welding to the outer door pillar element, allows a high rigidity of the door pillar, especially with regard to their properties in a side impact, which can nevertheless be kept relatively narrow.
  • the object of the invention is to provide a door pillar, in particular a B-pillar, and a motor vehicle body of the type mentioned above, on the one hand allows a lighter and simpler structure of the door pillar and on the other hand continue high rigidity of the door pillar especially at a 9.aufprail on the
  • the reinforcing element is provided only in an upper portion of the door pillar.
  • the invention is based in particular on the finding that it is sufficient to provide the reinforcing element only in an upper region of the door pillar, which is designed, for example, as a B pillar, in order nevertheless to maintain a sufficiently adequate rigidity of the door pillar.
  • a deformation of the door pillar in its upper region in the vehicle transverse direction inward can be at least largely avoided, which otherwise could, for example, lead to a corresponding airbag, for example a window airbag or a side airbag, not on the inside of the door pillar in the event of a side impact can unfold properly because the space between the inside of the door pillar and an adjacent headrest or a backrest is too short.
  • a sufficient rigidity of the door pillar is thus achieved in the upper part, so that in the event of a side impact sufficient clearance between the

  • the reinforcing element is designed as a reinforcing tube.
  • a further advantageous embodiment of the invention provides that a tube wall of the reinforcing tube has at least one passage opening for a spot welder, by means of which the reinforcing tube with the outer door pillar element by spot welding ishedragbar,

  • the reinforcing element ends with an upper end at a distance below a transition region in a roof frame.
  • a particularly optimized stiffening of the door pillar can be achieved, since it has been shown that a considerable deformation of the door pillar in the event of a side impact usually does not take place immediately after the corresponding roof frame.
  • Reinforcement element with a lower end above an attachment point for an upper door hinge. This results in a total of a particularly weight-optimized door pillar, which meets all stiffness and strength requirements in a side impact by far.
  • the outer door pillar element has at least one bead or the like in the area below the reinforcing element.
  • the door pillar is at least in the event of an accidental application of force as a result of a side impact
  • a Ausgestattung of the invention has proven to be advantageous in which the outer door pillar element in each case at least one bead or the like.

  • Cross section present about O-shaped reinforcing tube, by means of which the B-pillar 12 is reinforced.
  • the reinforcing element 22 for stiffening the B-pillar 12 is only in an upper portion of the door pillar or the B-pillar. Pillar 12 is provided and received in the present case within the substantially U-shaped column profile 1 1. This means that the reinforcing element 22 presently within the through the U-shaped column profile 11 of the outer door pillar element 10 and through the inner, not shown here
  • Door pillar element formed cavity or box section of the B-pillar 12 is arranged. As can further be seen in conjunction with FIGS. 2 and 3, this is
  • Reinforcing element 22 in the present case directly connected to the U-shaped column profile 11 of the outer door pillar element 10. Since both the reinforcing member 22 and the outer door pillar member 10 are formed of a metal alloy, in particular of a steel or aluminum material ", this is done by in the present case

  • the outer door pillar element 10 has two beads 32 or the like in the region below the reinforcing element 22, more precisely immediately above the column root 14. In the present case, these extend at least substantially horizontally and in the vehicle longitudinal direction, wherein in the present case a contour of the respective bead 32 that is at least substantially arcuate in cross-section is provided. In each case a bead 32 is above or
  • the beads 32 serve in an accidental force due to a side impact for targeted deformation of the B-pillar 12 so that it is preferably moved substantially parallel to their position shown here in the vehicle transverse direction in the direction of the vehicle center. This results in a relatively low load in the upper portion of the B-pillar 12, in which this is stiffened by the reinforcing element 22.
