Abstract

So that intake water cannot flow from a frame side member of the body structure by way of a seat cross member into an exterior side member of the vehicle, a so-called partition part is arranged between the frame side member and the seat cross member, which partition part comprises a basic part and an expansion foam arranged thereon. As a result of the effect of heat, the expansion foam can expand to such an extent that the passage surface in the seat cross member is closed off in a watertight fashion and water can no longer enter the cross member.
