Tubular side impact metal beam for integrated door structure of passenger car, has lateral flanges extending via connecting portions with parallel to plan circumferential region, flat peripheral region and transition sections

摘要

#CMT# #/CMT# The beam (1) has a central longitudinal section (2) with peripherally closed in cross section of a D-shaped hollow profile, which comprises a convex curved peripheral region and an opposite plan circumferential region (4). An open circumferential region and a flat peripheral region (10) are provided in C-shaped transition sections (8) between end-side connecting portions (6, 7) and the central longitudinal section. Lateral flanges (12) extend via connecting portions with parallel to the plan circumferential region, flat peripheral region and the transition sections. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a tubular side impact metal beam. #CMT#USE : #/CMT# Tubular side impact metal beam for integrated door structure of a passenger car. #CMT#ADVANTAGE : #/CMT# The lateral flanges extend via the connecting portions with parallel to the plan circumferential region, flat peripheral region and the transition sections, so that the side impact metal beam can be secured to the door structure in a properly secured manner, thus protecting the vehicle occupants in a better manner against the rear end collisions with lateral directions of attack, and hence reducing the installation space in the door and reducing the weight. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic perspective view of a tubular side impact metal beam. 1 : Tubular side impact metal beam 2 : Central longitudinal section 4 : Opposite plan circumferential region 6, 7 : End-side connecting portions 8 : C-shaped transition sections 10 : Flat peripheral region 12 : Lateral flanges.
