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

[0021] 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.

[0022] 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 vehicle body structure with a vehicle body pillar (3), in particular a B pillar, used for a vehicle, the vehicle body pillar has a hollow beam (9) and a reinforcing element(11) arranged thereon for improving side direction anti-collision strength, the reinforcing element has a head section (13) connected to a roof longitudinal beam (7), a support foot section (15) connected to a vehicle doorsill (1) and a middle pillar section (17) extending therebetween, the reinforcing element (11) has a predetermined deformation part (19) in a transition position between the middle column section (17) and the support foot section (15), during side direction impact, deformation of the vehicle body pillar (3) can be started at the predetermined deformation part, wherein the reinforcing element (11) has a U-shaped profile in the middle pillar section (17), and the U-shaped profile has a profile bottom (29) outside the vehicle along a transverse direction (y) of the vehicle and a side edge (33) stretching from the profile bottom to the inside of the vehicle along the transverse direction (y) of the vehicle and capable of being connected with an inner plate and an outer plate of the hollow beam (9).

Description

technical field [0001] The invention relates to a body structure for a double-track vehicle according to the preamble of claim 1 . 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 stiff...
