into the b pillar 1 of the vehicle from a side impact the motor vehicle body includes a dissipation device with one or more torsion segments which plastically twist or are plastically twisted owing to a rotation of the lower end of the b pillar to provide a more compact view fig1 depicts several different torsion segments together wherein one or more of these torsion segments can be omitted in one modification and or the dissipation device can exhibit one or more additional torsion segments that are not shown the dissipation device in the embodiment depicted includes two torsion segments 2 2 situated on either side of the b pillar 1 at the transitions between the legs 12 13 of the lever 10 and the rocker panel 2 the dissipation device in the embodiment depicted also includes two torsion segments 2 1 situated on either side of the b pillar 1 in proximity to the a or c pillar 3 4 which are thus each spaced apart from the b pillar 1 in the longitudinal direction of the vehicle by at least 30 of a length of the rocker panel and at least 75 of a distance between the b pillar 1 and adjacent a or c pillar 3 4 torsion segments 2 1 2 2 are designed with a locally reduced.
