Abstract

Falzverbindung zwischen einem Außenblech und einem Innenblech, wobei das Außenblech einen ungebogenen, an einer ersten Seite des Innenbleches anliegenden Abschnitt und einen eine Kante des Innenbleches umgebenden Biegeanschnitt aufweist, wobei der Biegeabschnitt einen ersten, sich an den ungebogenen Abschnitt anschließenden, einen Biegeradius aufweisenden Teilabschnitt, einen sich an den ersten Teilabschnitt anschließenden zweiten Teilabschnitt, welcher zusammen mit dem ungebogenen Bereich einen Winkel einschließt, dessen Scheitelpunkt in dem Bereich des ersten Teilabschnitts liegt, und einen sich an den zweiten Teilabschnitt anschließenden dritten Teilabschnitt, der im wesentlichen parallel zu dem ungebogenen Bereich des Außenbleches verläuft und an einer zweiten Seite des Innenbleches anliegt, aufweist.

Figure 00000001
Folded connection between an outer sheet and an inner sheet, the outer sheet having an unbent section lying on a first side of the inner sheet and a bending section surrounding an edge of the inner sheet, the bending section having a first section that adjoins the unbent section and has a bending radius, a second section adjoining the first section, which together with the unbent area forms an angle whose apex lies in the area of the first section, and a third section adjoining the second section which is substantially parallel to the unbent area of the Outer sheet extends and has a second side of the inner sheet.
