- the reinforcing screw 49 is clamped with a screw nut 53, which is on the outside
- the reinforcing screw bolt 49 is part of the screw connection S in FIG. 10, by means of which the sheet metal inner part 9 is screwed to the sheet metal outer part 11.
- the reinforcement screw bolt 49 extends with its longitudinal axis in the vehicle longitudinal direction x also through screw holes 51 of the sheet metal inner part screw-on flanges 41.
- connection of the sheet metal inner part 9 to the sheet metal outer part 1 1 can depend on
- the hollow beam 12 of the B-pillar 3 is divided into a head section B1, a middle section B2 and a foot section B3.
- the connection of the sheet metal inner part 9 to the sheet metal outer part 11 varies in the three sections B1 to B3 as follows:
- the connection in the head section B1 is designed to be particularly firm in order to be able to withstand a belt load caused by a crash.
- the middle section B2 should be subject to the least possible intrusion into the vehicle interior. Therefore, a particularly strong connection strength is provided in the middle area B2 below, which is reduced towards the top.
- the lower foot section B3 should be designed in such a way that, in the event of a side crash, with the reduction of crash energy, a deformation occurs in the region below the seat surface of the vehicle occupant. Therefore, the connection strength is deliberately weakened in the foot area B3. Such a weakened connection strength in the foot area B3 is preferred by a
- Attachment achieved with a continuous screw 49, as shown in FIG. 10. In the event of a side crash, this acts like a hinge with a predetermined breaking point.
- the sheet metal inner part 9 and the sheet metal outer part 11 have a positioning aid P.
- the sheet metal inner part 9 is pre-positioned in the correct position in a screwing position SP (FIG. 13) in which the sheet metal inner part 9 can be screwed to the sheet metal outer part 11 to form the aforementioned screw connections S.
- the positioning aid P has in FIG. 12 or 13 on the profile flank 33 of the sheet metal outer part 11 a positioning bolt 55 which extends from a base surface of the profile flank 33 in the
- Vehicle longitudinal direction x protrudes and has an expanded bolt head 57. This is spaced by a clear annular gap r from a base surface of the sheet metal outer part flank 33.
- the positioning bolt 55 interacts with a positioning link 49, which in the
- Screw flange 41 is formed.
- the positioning link 49 in FIG. 12 has an insertion section 52 which is open in the joining direction F (oriented in the vehicle transverse direction y) and which, opposite to the joining direction, merges into a vertical guide track 53 which protrudes from the insertion section 52 by a height offset Dz toward the vehicle .
- the sheet metal inner part 9 is first inserted with its insertion section 52 into the annular gap r between the bolt head 57 and the inner surface of the sheet metal outer part profile flank 33. Subsequently, the sheet metal inner part 9 under the effect of gravity
- Positioning bolt 55 rests.
- the annular gap r is dimensioned larger than the sheet thickness of the inner part screw-on flange 41.
- FIG. 14 shows a further embodiment of a screw connection of the sheet metal inner part 9 to the B-pillar 3 in a view corresponding to FIG. 5.
- the belt retractor 20 is mounted in the mounting opening 6 of the inner sheet metal part 9.
- a screw connection S is provided on each side of the height-adjustable belt deflector 23.
- Each of these screw connections S has a screw bolt 45, which in the
- Vehicle transverse direction y is aligned and is guided through a screw hole in the inner sheet metal part 9 and is screwed to a weld nut 47 fastened to the reinforcing sheet metal part 15. Therefore, in FIG. 14, the sheet metal inner part 9 is screwed directly to the reinforcing sheet metal part 15 via the screw bolts 47. The reinforcing sheet metal part 15 is in turn firmly connected to the inside of the sheet metal outer part 11.
