Definitions

  • the invention relates to a hollow profile for a side door of a motor vehicle according to the preamble of patent claim 1 and a side door for a motor vehicle according to the preamble of patent claim 7.
  • a side door be provided with a bumper, which is formed by a carrier.
  • the carrier is inserted from the outside of the motor vehicle into the door or into the side wall and is designed as a ramming bar. This can effectively prevent the door from being pushed into the passenger compartment in the event of a side impact.
  • the bracket is inserted on the outside of the door, the structural freedom of movement is significantly affected.
  • a hollow profile is known from EP 0 710 190 B1, which is arranged inside a side door of a motor vehicle is.
  • the hollow profile has a cross section which is formed by an outer jacket, stiffening ribs running in the direction of impact within the outer jacket. In the event of a side crash with high forces, the stiffening ribs can therefore damage the vertical walls of the hollow profile, so that the profile can be weakened.
  • the object of the invention is therefore to provide a hollow profile for a side door of a motor vehicle, which has higher moments of resistance.
  • the invention is intended to create a side door for a motor vehicle in which the side impact protection is improved even with very high forces.
  • the hollow profile has a cross section which is formed by an outer jacket, with at least two or more stiffening ribs crossing within the outer jacket. This means that the stiffening ribs have at least one common point of intersection within the outer jacket.
  • the stiffening ribs can come to rest against the side walls.
  • the hollow profile can have a small cross section with a high transverse force absorption. At the same time, the buckling behavior is improved despite the weight saving.
  • the outer jacket can have a substantially trapezoidal cross section, in order to achieve an approximately parallel course of the outer planking and side wall of the hollow profile with correspondingly limited installation space, the two sides running parallel to one another being erected horizontally.
  • the trapezoidal cross-section is essentially isosceles and that the edges of the outer jacket are rounded.
  • a cross section can be created that is approximately circular or elliptical, so that the large transverse forces can absorb.
  • Two stiffening ribs are preferably provided, each of which runs obliquely from one side wall to the opposite side wall, so that the two stiffening ribs must cross within the outer jacket.
  • the two stiffening ribs run diagonally within the outer jacket, that is to say from one corner of the trapezoidal cross section to the opposite corner.
  • the hollow profile is integrated into a side door of a motor vehicle, namely between an inner support structure and an outer paneling.
  • the hollow profile runs in the longitudinal direction of the vehicle, so that the two sides running parallel to one another are arranged horizontally, that is to say parallel to the roadway. If the vertical side walls significantly exceed the dimensions of the horizontal sides running parallel to one another, a large connection area can be made available to the outer paneling of the side door, so that the transmission of force in the longitudinal direction and when lowering is improved. At the same time, wall thicknesses can be reduced by providing a large cross section in the vertical direction.
  • FIG. 1 shows a cross section through a motor vehicle door in a first embodiment
  • Fig. 3 shows a cross section of a hollow profile according to a third embodiment
  • Fig. 4 shows a cross section of a hollow profile according to a fourth embodiment.
  • Figure 1 shows a motor vehicle door 1 with an outer paneling 2 and an inner support structure 3.
  • the inner support structure 3 receives a height-adjustable motor vehicle window.
  • the inner support structure 3 is closed off at the top by a parapet, not shown.
  • a hollow profile 6 is arranged at a horizontal distance from the window parapet 5, which extends in the longitudinal direction of the vehicle.
  • the hollow profile 6 has a uniform trapezoidal cross section, which is formed by a jacket 7.
  • the jacket 7 comprises two horizontal sides 8 and 9 running parallel to each other and two mirror-symmetrically arranged vertical side walls 10 and 11.
  • Two stiffening ribs 12 and 13 extend diagonally in the outer jacket 7 cross in a point 14.
  • the vertical side wall 10 facing the outer paneling 2 runs approximately parallel to the outer paneling 2.
  • the hollow profile 6 is preferably a
  • FIG. 2 differs from that in FIG. 1 only in that the hollow profile has a different cross section.
  • the hollow profile 6 ⁇ is also formed by an outer jacket 7 X , but which has a larger cross section in the horizontal direction.
  • the stiffening ribs 12 'and 13' do not run diagonally as in Figure 1, but diagonally from a horizontal side wall 10 to the opposite side wall 11. Nevertheless, the two stiffening ribs 12 and 13 'intersect within the outer casing 7 *.
  • the operation of the hollow profile 6 V within the side door is analogous to that in FIG. 1, with the larger cross-section in the vertical direction allowing the surface to be supported on the outer paneling 2.
  • 3 is a hollow profile 6 ⁇ with a rectangular cross-section and has a total of four stiffening ribs 15, 16, 17 and 18. The stiffening ribs form a kind of truss within the hollow profile.
  • the hollow profile 19 in FIG. 4 has completely rounded edges, so that an elliptical cross section results.
  • the stiffening ribs 20 and 21 intersect within the outer casing 22, as in the other exemplary embodiments.
  • the hollow profiles according to the invention can be produced both from plastic and from light metals such as aluminum.

Abstract

L'invention concerne un profilé creux (6) d'une portière latérale d'un véhicule. La coupe transversale de ce profilé est constituée d'une enveloppe externe (7). Des raidisseurs (12) et (13) s'étendent dans cette coupe transversale. L'invention vise à améliorer la protection de collision de flanc même dans le cas de forces élevées. A cet effet, les raidisseurs (12, 13) se croisent dans la section transversale.
