Abstract

The structure has side coverings (1) in form of sheet pressed parts and settable outside against and connected to a shell body of a motor vehicle e.g. small-sized passenger car, by stiffening elements. The side coverings are formed by a one-piece covering lower part (3), which extends to a rear interior region and extends downwardly from a waist line (2) of the vehicle. The covering lower part is assignable to arbitrary upwardly extending one-piece covering upper parts (4', 4'') based on a desired vehicle type and the waist line.

Description

The The invention relates to an outer skin structure in the field of Passenger compartment of a motor vehicle, in particular a passenger car, according to the preamble of claim 1.

From the DE 195 00 361 A1 is a body for a passenger car, especially for a small car, known, in which the supporting structure of the body is formed by a so-called space-frame construction. The lying above a waistline profiles of the truss structure are each free with their outwardly facing flat side, are formed in this area respectively according to the desired surface course of the body and form an immediate body surface. In contrast, the truss structure below the waistline with a plurality of detachably connected to the truss structure cladding parts without supporting function disguised, making dimensional and formal body alternatives should be producible and available, but require increased tooling costs for said body alternatives.

With the EP 0 760 329 B1 Further, there is disclosed a side panel assembly for a motor vehicle body which extends rearwardly from at least an A-pillar to a rear vehicle longitudinal direction and has a sidewall structure and a side wall panel joined thereto, wherein the sidewall panel is fabricated as a one-piece sheet metal stamping and covers sidewall structures that do not already form the outer skin itself. Due to the large areas and the resulting large drawing depths, possible design alternatives, which are accompanied by strong contours and large slopes or bends, are very quickly set limits.

The DE 197 53 207 C2 further discloses a bodywork segment for a vehicle having, inter alia, a multi-part sidewall skin composed of an A-pillar outer, a B-pillar outer and a C-pillar outer and extending only to the sill in turn is disguised separately. Although problems regarding increased drawing depths are not recorded to this extent, however, this sidewall planking requires increased tooling costs.

Finally, out of the EP 1 436 189 B1 a method for producing a side wall assembly of a motor vehicle body with a one-piece plank known, which in turn is deep drawn from a board and cut in the pressing tool to form driver and fondseitigen window openings and door openings. Again, due to the large areas and the resulting large drawing depths possible design alternatives very quickly set limits.

Of these, Based on the object of the invention, an outer skin structure in the area of the passenger compartment of a motor vehicle, in particular a passenger car, with side skins in the form of sheet metal stampings to create which with minimal tooling for the production the outer skin structure or Seitenbeplankung on the one hand within wide limits design alternatives, with strong contours and large bumps in the side paneling on the other hand, also permits alternatives in the vehicle type.

outgoing from an outer skin structure in the area of the passenger compartment a motor vehicle, in particular a passenger car, with on both sides of the same arranged side skins in the form of Sheet metal stamping, which in turn with the possible use of stiffening elements from the outside against the body shell of the motor vehicle settable and are attachable to the same, the task is thereby solved that the Seitenbeplankung on both sides of the motor vehicle by one piece each and from the front to the to the rear passenger compartment and from a belt line of the motor vehicle downwardly extending planking base is formed, which starting from said waistline an upwardly extending and depending on desired vehicle type freely selectable one-piece Plankungsoberteil is assignable.

Beplankungsunterteil and Plankungsoberteil are advantageous in the area of the waistline with each other positively, positively and / or firmly bonded connectable. The waistline of the motor vehicle extends expediently seen in the vehicle longitudinal direction at the level of the lower edge of lateral window openings of the Side platings.

Especially Advantageously, the planking base comprises the cover for a lower A, B and C-pillar section, a side rail and a rear wheel arch. In contrast, the planking upper part depending on the desired vehicle type, for example the cover for an upper A, B and C-pillar section as well as a roof rail of a limousine or the cover for an upper A-pillar section a convertible vehicle.

The proposed skin structure has several advantages over conventional ones. On the one hand allows the separation of the outer skin or planking of the vehicle body in Brüs height at the level of the lower edge of the lateral window cutouts within wide limits design alternatives, which in turn are accompanied by strong contouring and large falls or curvatures in the Seitenbeplankung. On the other hand, there is advantageously the opportunity to form a convertible derivative with a positive tool balance and accordingly with little effort from a sedan.

The The invention will be described below with reference to the drawings illustrated embodiments explained in more detail. Show it:

1 the left-hand outer skin structure of a motor vehicle in the area of the passenger compartment,

2 the section II after 1 .

3 the section II-II after 1 .

4 very schematically the outer skin structure with two separate Seitenbeplankungen acc. a first possible embodiment, and

5 very schematically the outer skin structure with two separate Seitenbeplankungen acc. another possible embodiment.

Then show the 1 to 4 an outer skin structure, in this case the outer skin structure arranged on the left-hand side in the region of the passenger compartment of a motor vehicle, in particular a passenger car, wherein the right-hand side is preferably of a similar design, with a side paneling 1 in the form of pressed sheet metal parts with window and door cutouts 1a . 1b , which in turn can be set from the outside against a known and not shown here in detail shell body of the motor vehicle and attachable to the same.

The Sheet metal stamping can be internal stiffening elements be assigned to a variety of design, but not directly related to the subject invention and accordingly not are shown in more detail.

As already demonstrated, are conventional due to large areas and resulting large Draw depths of possible design alternatives that come with strong Contours and large drops or curves go along with certain limits.

To counter this problem is the side paneling 1 on both sides of the motor vehicle, first by a one-piece and from the front to the rear passenger compartment and a belt line 2 of the motor vehicle downwardly extending planking base 3 educated.

The planking base 3 this includes the cover 3a . 3b . 3c for a lower A, B and C-pillar section, a cover 3d for a side rail, also referred to as a sill, and the cover 3e for a rear wheel arch of the bodyshell.

The planking base 3 Furthermore, depending on the desired vehicle type freely selectable a one-piece Plankungsoberteil 4 ' or 4 '' attributable to which of said waistline 2 extends upwards and with the planking lower part 3 in the area of the waistline 2 force, form and / or material firmly firmly connected.

So For example, can be known per se mechanical fasteners and / or per se known welding or adhesive method Find use.

Like in the 3 shown in more detail, is the joining area 5 between planking base 3 and plank top 4 ' in the area of the waistline 2 by parked to the vehicle interior connecting webs 5a . 5b formed and accordingly advantageously not visible from the outside, where expediently the waistline 2 of the motor vehicle seen in the vehicle longitudinal direction in height of the lower edge of the lateral window cutouts 1a the side skins 1 , in the present case of the planking upper part 4 ' extends.

According to the 1 and 4 includes the plank top 4 ' with regard to a limousine to be manufactured the cover 6a . 6b . 6c for an upper A, B and C pillar section as well as a cover 6d for a roof rail of the roof frame of the shell body not shown in detail.

Alternatively, however, it is also possible, instead of a planking upper part 4 ' for a sedan a plank top 4 '' for a convertible vehicle to be used, which according to the 1 (dash-dotted lines) and 5 the cover 7 for a top A-pillar portion of the known per se and thus not shown in detail shell body of the convertible vehicle.
