- the compliance of the Befest onlysab- section 110 can be adjusted specifically.
- FIG. 12 shows a variant for a weakening of the fastening section 110. It can be seen that, viewed in the extrusion direction S, recesses or holes 300 are provided in front of and behind the fastening section 110, which are either only in the fastening surface 70 or in addition to the fastening surface 70 have been introduced into one of the two support walls, preferably the outer support wall. Through the holes 300, the fixing portion 110 becomes yielding without itself directly communicating with one of the holes.
- FIG. 13 shows a further exemplary embodiment of a car body part 10, which is formed by an extruded part 11 which is extruded along the extrusion direction S.
- the extruded part 11 has an extruded fastening rail 400 with an (at least in sections) open profile, for example an L-profile.
- the profile of the fastening rail 400 can be produced in the context of the extrusion press process as an open profile; Alternatively, the profile of the mounting rail 400 can be made as a closed profile in the extrusion process and only locally or continuously opened by post-processing.
- the fastening rail 400 is at points along the extrusion direction S one behind the other
- the fastening sections which are formed by the upper fastening surface of the fastening rail 400, are identified in FIG. 13 by the reference numeral 420. On the rear side in FIG. fixing portion 420, a fastener of a piece of equipment 30 is mounted.
- the above embodiments may have one or more of the following features:
- the shell-side mounting rail of the car body part is mechanically processed so that the outer vertical web (support wall 72 in Figures 1 and 3) of the mounting rail in the region of the mounting portion or the Verschraubungsflache completely or at least partially eliminated.
- the inner vertical web of the mounting rail transmits directly the vertical weight, because it is in communication with the horizontal support surface and at least partially covered by this.
- the horizontal bearing surface serves as a screwing surface and transmits longitudinal and transverse forces.
- the mounting rail for a torsion about the longitudinal axis of the mounting rail and around the axis of the pressing direction of the extruded profile is more flexible without losing strength at the relevant bearing points.
- the fastening sections or the bolting surfaces can be brought to the desired installation under the pretensioning force.
