Abstract
Official abstract text for this publication.
A B pillar of a motor vehicle with a base region and a head region; in the base region, there is a contact region with a connecting region for connecting the B pillar to a rocker panel; over the span of its height from a base edge to a B pillar head, the B pillar has hard and soft regions, wherein the B pillar has a soft region, which extends from a contact region of the B pillar with the rocker panel to the B pillar head and in this case, extends for at least 100 mm.
First claim
Opening claim text (preview).
The invention claimed is: 1. A B pillar of a motor vehicle, comprising: a base region; a head region; and a contact region in the base region with a connecting region for connecting the B pillar to a rocker panel; over a span of its height from a base edge to a B pillar head, the B pillar has hard and soft regions, wherein the B pillar has a first soft region, which extends from a contact region of the B pillar with the rocker panel to the B pillar head for a distance of at least 100 mm, and a second soft region below the connecting region of the B pillar with the rocker panel, which extends to the B pillar base region. 2. The B pillar according to claim 1 , wherein the first soft region extends from an upper contact region of the B pillar with the rocker panel to the B pillar head. 3. The B pillar according to claim 1 , wherein the fit soft region extends beyond a fold line between the contact region and a B pillar outside and into the contact region. 4. The B pillar according to claim 2 , wherein in the contact region, at least one connecting region, in which the joining points with the rocker panel are positioned, is embodied as hard. 5. The B pillar according to claim 1 , wherein the B pillar is hardened above the fit soft region. 6. The B pillar according to claim 1 , wherein the hard regions have a tensile strength >1,400 N/mm 2 and the soft regions have a tensile strength <850 N/mm 2 .
