Problems solved by technology

However, excessive lateral impact forces create the risk that, even with stiffening elements, an uncontrolled bending of the body column into the vehicle interior would still result.

Embodiment Construction

[0020] exist figure 1 A vehicle is shown in , wherein the side wall components of the body-in-shell are highlighted in a partial section in the central vehicle region along the vehicle longitudinal x. The body-in-white has a lower vehicle side member, not shown, which transitions into a lateral door sill 1 in the region of the vehicle passenger compartment. The B-pillar 3 of the side wall assembly is arranged behind the A-pillar 5 in the vehicle longitudinal direction x and connects the lower rocker 1 of the vehicle body with the roof rail 7 of the roof frame in the vehicle height direction z.

[0021] The B-pillar 3 is used, on the one hand, to stiffen the body laterally and, on the other hand, to accommodate components such as seat belt retractors or the like. The B-pillar 3 is here embodied as a hollow beam 9 consisting of shell-like inner and outer panels 23 , 21 , as figure 1 or figure 2 shown. The lateral impact resistance of the B-pillar 3 in the event of a lateral...

Abstract

The invention relates to a body structure for a vehicle having a body column (3), in particular a B-pillar, having a hollow beam (9) and reinforcing elements arranged thereon for increasing the lateral impact resistance ( 11), the reinforcing element has a head section (13) connected to the roof rail (7), a foot section (15) connected to the door sill (1) and a central column section (17) extending therebetween ), wherein the reinforcing element (11) has a predetermined deformation point (19) at the transition point between the central column section (17) and the foot section (15), at which it can start at the predetermined deformation point during a side impact A variant of the body pillar (3), wherein the reinforcement element (11) has a U-shaped profile in the center pillar section (17) with a profile base outside the vehicle in the transverse direction (y) of the vehicle (29) with sides (33) protruding from the bottom of the profile in the transverse direction (y) of the vehicle towards the interior of the vehicle, which can be connected to the inner and outer panels of the hollow beam (9).

Description

technical field [0001] The present invention relates to a body structure for a dual-track vehicle. Background technique [0002] The B-pillar of such a vehicle extends substantially in the vertical direction between the roof rails of the vehicle and the underside door sills. The B-pillar is used, on the one hand, to stiffen the body laterally and, on the other hand, to accommodate components such as seat belt retractors or the like. Furthermore, the B-pillar delimits the door openings at the front and, if applicable, the door openings at the rear of the vehicle. In order to increase the lateral crash resistance in the event of a side impact, reinforcing elements are integrated into the B-pillar, which counteract the deformation of the B-pillar into the vehicle interior caused by an accident. However, excessive lateral impact forces run the risk of uncontrolled bending of the body column into the vehicle interior despite the presence of stiffening elements. [0003] A type...
