FIELD: transport. ^ SUBSTANCE: invention relates to machine building, namely to automotive body structural elements. Proposed device aims at increasing transport facility body stiffness and comprises U-cross section central tunnel of transport facility which is jointed via sidewalls to the body bearing base. Crosswise rails for seats are arranged on both sides jointed to body bearing base and/or said central tunnel. Central tunnel lower side that faces body bearing base has a tunnel bridge. Said tunnel bridge comprises at least two crosswise rails and lengthwise rails jointed thereto. Crosswise rails run under the central tunnel supports, across transport facility, to allow their free ends to be fastened in holes made in the body. ^ EFFECT: higher stiffness. ^ 9 cl, 5 dwg |
