Reinforcing element for amplifying longitudinal and lateral surfaces of multi-chamber hollow profile i.e. car body, has arm sections inserted into hollow section interior over insertion opening formed on side surface of hollow section

摘要

The element (1) has a bolt portion (1a) including a pair of opposite distant arm sections (3, 4) axially displaced at ends of contact surfaces (3a, 4a) with respect to the bolt portion. The arm sections are inserted into a hollow section interior over an insertion opening (11) formed on a side surface (10a) of a hollow section (10) such that the ends of contact surfaces of the arm sections are in abutment engageable with longitudinal surfaces of the hollow section by rotating movement of a head portion (1b) on the side surface into a mounting position. An independent claim is also included for a multi-chamber hollow profile.
