Embodiment Construction

[0030] figure 1 The profile 10 contained in the B-pillar of the vehicle is shown. The profile 10 extends in the longitudinal direction L and is generally hat-shaped with a central flange 12 and two sides 14 , 16 . Seen in the longitudinal direction of the profile, the sides 14 , 16 each have an outwardly directed flange 18 , 20 . The profile is also arranged with attachment areas 22, 24 for door hinges, for example the upper and lower door hinges of the rear doors of a car. The attachment areas 22, 24 may be arranged with fastening elements, such as holes 26 for attachment bolts of a hinge. However, it should be understood that there may be other types of fastening elements and more than two attachment areas along the extension of the profile.

[0031] In order to strengthen the profile 10 and provide it with desired impact force handling characteristics without unduly increasing the weight of the finished B-pillar, reinforcement elements 30 are attached to the profile 10 ....

Abstract

The present application relates to a reinforcement element (30) arranged to be attached to a profile (10) for forming a B-pillar for a vehicle, which profile (10) is arranged with attachment areas (22, 24) for door hinges, characterised in that the reinforcement element (30) is designed with two elongated strips (32, 34) of material, wherein the strips (32, 34) are inter-connected at least at one attachment area (22) for door hinges when the reinforcement element (30) is attached to profile (10), wherein the profile (10) is hat-shaped with a central flange (12) and two sides (14, 6), and wherein each strip (32, 34) is attached to the transition area (36, 38) between the central flange (12) and a side (14, 16).The present application also 10 relates to a B-pillar provided with the reinforcement element as well as a method of manufacturing a B-pillar with the reinforcement element.

Description

technical field [0001] The invention relates to a reinforcing element for a pillar of a vehicle, in particular a so-called B-pillar, which forms part of the bodywork of a motor vehicle, such as an automobile. Background technique [0002] The struts of a motor vehicle are required to withstand high strains, such as during a crash. Modern designs include struts that are strengthened by adding material in certain areas along the extension. For example, it is known to place sheet metal reinforcements on sheet metal blanks, weld them together and then form struts by thermoforming and hardening in a press hardening process. This is known, for example, from WO 2014 / 017961. Here, the reinforcing plate is attached to the slab used to form the B-pillar. The reinforcement plate is designed such that at least 1 / 4 of its length has a width corresponding to the hat profile of the B-pillar and then narrows at its ends so that it does not extend the full width. With this design, compar...
