Abstract

The wall (1) has horizontally running impact bars (8) for blending impact energy on the wall and spaced at a distance from the wall. The bars are connected with vertically arranged fins with the wall, where the fins are flexibly designed over its extension between the wall and the bars in a lateral direction to accommodate different horizontal linear expansions of the wall and the bars. A lateral deflection is included for the fins corresponding to its flexible design in the lateral direction.
