Embodiment Construction

[0044] figure 1 A B-pillar center beam 100 is depicted, typically welded to a rocker at a lower fastening portion 105 and welded to a roof panel of a vehicle, such as an automobile, in an upper fastening portion 101 . The B-pillar is located between the front and rear seats of the vehicle, and it is also useful for different purposes. As mentioned before, it supports the skeleton structure of the vehicle and provides a safety barrier in the event of a vehicle collision.

[0045] In some embodiments, a B-pillar may include a center sill, an outer panel and an inner panel, and optionally another central reinforcement (center means herein between the outer panel and the inner panel). The interior panel can be used to attach parts to the interior of a vehicle (eg, a car). The outer panel may in particular be used to provide a complementary shape to a car door. According to certain embodiments, both the inner and outer panels may contribute to the structural strength and stiffn...

Abstract

In a first aspect, a B-pillar center beam made of steel includes a hard region and a soft region. Such soft regions have a lower mechanical strength than the hard regions. The B-pillar center beam also includes an upper region having a fastening portion for fastening to a roof member and a lower region having a fastening portion for fastening to a bottom beam member. The B-pillar center beam includes two soft zones. A lower soft zone is located between 50% of the height of the B-pillar center beam and the lower fastening portion, and an upper soft zone is located between 50% of the height of the B-pillar center beam and the upper fastening portion. The upper soft zone has a higher mechanical strength than the lower soft zone. A method for manufacturing such a B-pillar center beam is also provided.

Description

technical field [0001] This application is related to and claims the benefit and priority of EP15382640.9 filed on December 18, 2015. The present disclosure relates to B-pillars, and more particularly to B-pillar center beams with soft zones. Background technique [0002] A vehicle (eg, an automobile) contains a structural skeleton designed to withstand all the loads the vehicle may experience during its lifetime. The structural skeleton is also designed to withstand and absorb impacts, in the event of collisions with eg other cars or obstacles. [0003] In this sense, the structural skeleton of a vehicle (eg, an automobile) may include, for example, bumpers, pillars (A-pillar, B-pillar, C-pillar), side impact beams, rocker panels, and shock absorbers. For the structural skeleton of a car, or at least for many of its components, it has become commonplace in the automotive industry to use so-called ultra-high-strength steels (UHSS), which exhibit optimized maximum strength ...
