Problems solved by technology
In fact, stamped parts are prone to elastic recovery, so that the precise alignment of the edges of the parts required for laser welding is often not achievable
However, spot welding results in the formation of discontinuous welded joints, which may weaken the resistance of the door frame

Abstract
Methods for producing a three-dimensional vehicle door frame inner reinforcement element, for producing a vehicle door frame and for producing a vehicle reinforcement structure A method for producing a three-dimensional vehicle door frame inner reinforcement element (52) comprising an inner center pillar part (66), an inner front pillar part (68) and an inner side rail part (64) joining the inner center pillar part (66) and the inner front pillar part (68). The method comprises: - providing an inner center pillar blank, an inner front pillar blank and an inner side rail blank, said inner blanks being substantially planar, - assembling the inner center pillar blank and the inner front pillar blank to the inner side rail blank in order to form a substantially planar door frame inner reinforcement blank, - hot stamping the door frame inner reinforcement blank to shape the three- dimensional door frame inner reinforcement element (52).
Description
technical field [0001] The present invention relates to a method of manufacturing a three-dimensional vehicle door frame interior reinforcement element comprising at least an interior center pillar portion, an interior front pillar portion and an interior stringer portion joining the interior center pillar portion to the interior front pillar portion. [0002] In particular, the invention relates to the manufacture of vehicle reinforcement elements such as interior reinforcement elements of door frames. More particularly, the invention is applicable to body-on-frame vehicles, such as pickup trucks. Background technique [0003] Conventionally, vehicles include stiffening elements intended to protect the vehicle by limiting any type of intrusion into the vehicle's passenger compartment in the event of a crash, especially in the event of a side impact, frontal impact or roof crush during a rollover accident passenger. [0004] The stiffening elements comprise a body side str...
