Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present disclosure will hereinafter be described in conjunction with the following drawing figures, wherein like numerals denote like elements.

[0030] FIG. 1 shows a part of a motor vehicle body of a passenger car according to an embodiment of the present disclosure;

[0031] FIG. 2 is a cross member of the motor vehicle body, and

[0032] FIG. 3 is the cross member during the production of the motor vehicle body according to an embodiment of the present disclosure.

DETAILED DESCRIPTION

[0033] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description.

[0034] FIG. 1 shows a part of a motor vehicle body of a passenger car according to an embodiment of the present disclosure with a left side-sill member or side sill 10, a B-pillar 20 arranged on the side sill 10, the cross sections of which, perpendicularly to a vehicle vertical direction (from the bottom up in FIG. 1) include a first or front side 21 in a vehicle longitudinal direction from a vehicle front to a vehicle rear (from the right to the left in FIG. 1) and a second or rear side 22 following in this vehicle longitudinal direction.

[0035] On the side sill 10, a cross member 300 is attached, which is adjacent to a pillar-next cross member 40 in the vehicle longitudinal direction. The cross member 300 includes a sill-side end section 310 (top in FIG. 2) and a connection section (320), which are separately produced and subsequently connected to one another to form the cross member 300, as indicated in FIG. 3.

[0036] The end section 310 includes a first or front side wall 311, in the vehicle longitudinal direction, and a flat following second or rear side wall 312 in the vehicle longitudinal direction, the connection section 320 accordingly a flat first or front side wall 321 in the vehicle longitudinal direction, and a flat, second or rear side wall 322 following in the vehicle longitudinal direction.

[0037] As is evident in particular from viewing FIGS. 1, 2 together, the front side wall 311 of the end section 310 and the front side wall 321 and rear side wall 322 of the connection section 322 run parallel to the vehicle transverse direction, while the second side wall 312 of the end section 310 is slanted against the vehicle transverse direction by an angle of approximately 40°.

[0038] For this reason, its distance in the vehicle longitudinal direction from the second side 22 of a sill-adjacent or lowermost (connection) cross section of the pillar 20 decreases linearly in the vehicle transverse direction towards the side sill 10, while a width of a cross section of the end section 310 that is perpendicularly to the vehicle transverse direction correspondingly increases linearly in the vehicle transverse direction towards the side sill 10.

[0039] As is evident in particular in FIG. 1, a flat upper cover wall 313 of the end section 310 is slanted upwards, so that its distance in the vehicle vertical direction from the pillar 11 decreases linearly in the vehicle transverse direction, while a height of a cross section of the end section 310 that is perpendicular to the vehicle transverse direction correspondingly increases linearly in the vehicle transverse direction towards the side sill 10. The end section 310 is, as indicated in FIG. 3, produced as a bent sheet metal part so that its cross sections each include a U-shaped profile perpendicularly to the vehicle transverse direction.

[0040] Following this, the connection section 320 is introduced and via wings 314 of a flange formed integrally with the end section 310 welded, soldered or glued to the same for supporting itself on the connection section 320 from the inside with a bead 315. In the state in which it is introduced into and connected to the connection section 320, the end section 310 engages over approximately ⅓ of its overall length in the connection section 320, as is evident in particular by viewing FIG. 1, 2 together. The end section 310 includes a plurality of face flanges 316 which are spaced from one another, which have been or are welded, soldered or glued to the side sill 10. In addition, end section 310 and also the connection section 320 have been or are welded, soldered or glued to a floor panel 50 via flanges.

[0041] While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment, it being understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the invention as set forth in the appended claims and their legal equivalents.
