CS267671B1 - The back of the car body, especially the driver's cab - Google Patents

Abstract

The field of application is the production of automobiles, the object of application is automobile bodies, especially driver's cabs. The aim of the solution is to process the structure of the rear wall, having a high absorption capacity, the manufacture of which is not associated with large expenses for tools. The task of the solution is to create a rear wall, differing in a small number of different components, the shape of which is optimally selected to absorb the effort. According to the solution, the rear wall is double, with the inner wall (1) and the outer wall (2) having the same shape and being connected together in such a way that vertical, horizontal and inclined grooves (3, 4, 5» 9) are formed over a specified distance. Horizontal grooves (4) are located under the rear windows (8), the outer ends of which rest on the beams (6) via inclined grooves (9). All cavities between the inner wall (1) and the outer wall (2) are connected to each other and have common ventilation holes (11) and outlet holes (12).
