Vehicle body with side stiffeners.

p0001The invention relates to a motor vehicle body said in the preamble of claim 1 and, for example, from DE-AS 19 55 058 (8) arising Art.

p0002As more and more electrical appliances are installed in a passenger car, must also correspondingly more electrical cables, which are combined to form cable harnesses are routed. The suitable for their accommodation installation space is however limited availability, so that sometimes time-consuming workarounds for installation of cable harnesses must be taken into account.

p0003The object of the invention is therefore to provide an opportunity for an automobile body said in the preamble of claim 1 kind, by a harness or the like elongate member in as simple and it can be accommodated especially in space-saving manner.

p0004To achieve the object, the features set forth in the characterizing portion of claim 1 are provided.

p0005By erfindunsgemäße forming the longitudinal recess on portions of the side wall and / or the bottom plate of the present between the side wall portion and the bottom plate portion, untapped cavity for the arrangement of the longitudinal trough can be utilized in an advantageous manner, so that ultimately the cables to be laid trees without any additional installation space can be accommodated in the vehicle interior. The longitudinal recess is by mere sheet metal forming, without additional effort and almost no increase in weight produced. Here also the harnesses can be timesaving mounted.

p0006When forming the longitudinal trough at the bottom plate section, this is very efficient to produce. Further, in this case, the wiring harnesses can easily into the vehicle interior open longitudinal trough are inserted from above (features of claim 2).

p0007Through several between the bottom of the longitudinal recess and the facing side wall portion arranged partition plates, the strength of the sill will firstly increases. Moreover, waves of vibrations are in the range of the sill by the partition plates largely prevented (features of claim 3).

p0008The vehicle interior is open towards the longitudinal trough can by expediently made of plastic wall part having a plurality of through holes - are covered, so that an air duct is formed by the wall part in a simple way - that flow into the vehicle interior. For preventing heat exchange between the latter and the longitudinal hollow is a thin-walled partition element, heat insulation film or the like are provided (features of the claims 4 to 6).

p0009Thus, the stiffness of the vehicle body is not reduced by the inventive design longitudinal trough in the region of the central support post, one attached to the support posts and the floor panel support strut is provided according to the features of patent claim 7.

p0010An embodiment of the invention is illustrated in the drawing and is explained in the following. It shows:<ul><li>Figure 1 is a perspective view of the sill area, with longitudinal trough and air duct from the vehicle interior,</li><li>Figure 2 is a vertical section in the front portion of the sill in a larger scale.</li></ul>

p0011The area shown in the figures 1 and 2 a sill 1 runs on the two long sides of a passenger car body, the sill shown in Figure 1 1 right-hand side is in the direction of travel. This consists of a horizontal body at the lower edge of side wall portion 2 and a floor panel section 3, which are interconnected by a peripheral flange 2 'to form a lying on the body base overlap. The sidewall portion 2 is toward the vehicle outer side bulged (Figure 2) and thereby closing in the area of ​​the sill 1 to the bottom plate section 3 a cavity a a. This is a piece on the bottom plate portion 3 formed, in cross section, approximately U-shaped longitudinal recess 30 is arranged, the bottom 30 'is directed toward the vehicle outer side, so that it is open to the interior of the vehicle b. However, it is also conceivable that a respective longitudinal recess is both in the sidewall portion 2 and the bottom plate portion 3 is formed, which are at the same height and side, are open to the Fahzeuginnenraum b. Finally, the bottom plate section 3 and the side wall portion 2 are connected to an overhead 2˝ longitudinal seam welded together.

p0012As can be seen in Figure 1, are four partition plates 5 are inserted between the bottom 30 'of the longitudinal recess 30 and the wall region lying opposite the side wall portion 2, which serve to increase the strength of the rocker panel 1 and to prevent vibration from vibrations. The partition plates 5 are connected at their overhead and underlying, approximately horizontally extending edges with the sidewall portion 2 by spot welding, while they are connected at approximately vertically extending outer edges each have two blowing gum pieces 6 with the bottom 30 'of the longitudinal recess 30 and the side wall 2 , In the illustrated embodiment, the baffle plates 5 each in the area of ​​the front, middle and rear support post 7, 8, 9 (B; A C-pillar) are disposed, which are integrally formed on the sill first If necessary, of course, can be 5 provided at any place more than four baffle plates.

p0013The longitudinal recess 30 formed on the bottom plate portion 3 to form an overhead and underlying longitudinal edge 30˝, where under cover of the longitudinal recess 30 a along the rocker panel 1 extending wall part 10 is screwed. This has a plurality of through openings 11 which are directed into the vehicle interior space b. Because of the wall part 10 is expediently designed as a plastic injection molded part, and in this case formed in two parts, the dividing line of the two longitudinal parts is in the range of the central support post. 8 The wall part 10 is finally 30 bolted to the overhead and underlying longitudinal edge 30˝ of the longitudinal recess with the interposition of a thin-walled, made of asbestos or the like separating element 12 so that the discharge of cool or heated air are forming air duct c is formed. This is separated by the thin-walled partition element 12 of the longitudinal cavity D of the longitudinal recess 30, wherein the thin-walled partition element 12 may be covered for reliably preventing a heat exchange between the cavity d and the air guide channel c with at least one heat protection film. Here, the cavity D of the longitudinal recess 30 may have cm² cross-sectional area of, for example 95, while the cross-sectional area of ​​the air duct C around 35 cm may be. There is also the possibility that the wall part 10 extends in the area of ​​the rear support post 9 to form a bend to the vehicle longitudinal central region.

p0014Thus, the central support post 8 is reliable in terms of strength to the bottom plate section 3 in conjunction, is a rigidly constructed, approximately Z-shaped extending support brace 13 bolted to the lower end of the central support post 8, which with its bottom end section under cover of the wall 10 to a seat carrier 14 is screwed. This in turn is secured in the region of the overlap 2 'of the sidewall portion 2 to the floor panel portion 3 and extends in the region of the central support post 8 in the vehicle transverse direction. Of course, the support bar 13 can be also attached at its bottom end section directly on the floor panel section. 3

p0015Since the cavity d the longitudinal recess 30 to the vehicle interior b is open, can of this out from above and thus in a convenient manner, a number of non-illustrated wiring harnesses and / or the like elongate members into the cavity d the longitudinal recess 30 are used, the individual wires are then connected to the respective electrical loads. After arranging the wire harnesses in the cavity D of the longitudinal recess 30, this is covered by the thin-walled partition element 12 and possibly by the two-piece wall part 10th Meanwhile, both parties are relatively short, so that it contains 30 simple b can be handled for its mounting on the longitudinal edges 30˝ of the longitudinal recess in the vehicle interior. Because until recently the support strut 13 is bolted to its attachment points, the mentioned assembly of wiring harnesses, the partition member 12 and the two wall 10 is unimpeded feasible.
