Definitions

  • the present invention relates to a vehicle door reinforced against side impacts. It is known that motor vehicle doors conventionally comprise an outer panel and an inner box panel interconnected at their lower part by a door bottom wall extending transversely with respect to the two panels.
  • motor vehicle doors are often reinforced by reinforcing bars extending behind the outer panel of the door and located substantially halfway up the door.
  • these reinforcement bars are insufficient to prevent the door from opening towards the inside of the vehicle, during a side impact at a speed of less than 60 km / h.
  • This opening of the door towards the interior of the vehicle is detrimental to the passengers.
  • This opening is due to too low resistance of the lower part of the door located under the aforementioned reinforcement bars. Indeed, this too low resistance allows it to deform by passing over the rabbet of the subwoofer of the vehicle. The lower part of the door is no longer retained by this rabbet, the door can open inwards, seriously injuring or even killing passengers.
  • the object of the present invention is to overcome this disadvantage by reinforcing the lower part of the doors of motor vehicles.
  • the motor vehicle door comprising an outer panel and an inner box panel interconnected at their lower part by a door bottom wall extending transversely with respect to the two panels, is characterized in that said door bottom wall is reinforced by a reinforcing element fixed to this wall and extending along a preponderant part of the length and width of this wall.
  • said reinforcing element is constituted by at least one metal plate having a greater thickness than that of said bottom door wall.
  • said reinforcing element is a metal plate one of whose longitudinal edges is fixed against the inner face of the inner box panel and whose other longitudinal edge is fixed against the inner face. the bottom wall of the door, near the outer panel.
  • said plate forms an acute angle with the inner box panel and with the wall of the door bottom and has, on each of its longitudinal edges, a folded edge parallel to the wall to which it is attached.
  • said reinforcing element comprises at least one bar fixed against the outer face of the door bottom wall.
  • said bar is fixed in a recess stamped in said bottom door wall, so that the outer face of said bar is located substantially in the extension of the wall portion lower door located outside said recess; one of the longitudinal edges of the bar is located substantially in the extension of the inner casing wall, so as to be located opposite the rabbet formed in the subwoofer box of the vehicle, when the door is closed.
  • said longitudinal edge has a peak-shaped cross-section adapted to be able to sink into the adjacent rebate of the sill in the event of a side impact on the door.
  • This provision provides increased protection in case of side impact, further reducing the risk of opening the door to the interior of the vehicle.
  • the bottom of the door is reinforced both by at least one plate of the type described above and by at least one bar as described above.
  • FIG. 1 is a perspective view of a motor vehicle door whose outer panel has been removed, showing a reinforcing element of the wall of the door bottom
  • FIG. 2 is a cross-sectional view of a motor vehicle door comprising the reinforcement element and the vehicle sill box
  • FIG. 3 is a view similar to FIG. 2, showing the deformation of the door. under the effect of a side impact
  • Figure 4 is a cross-sectional view of a door and the sill box of a vehicle, the wall of the door bottom being reinforced by a bar
  • the figure 5 is a view of the inner face of a door and the wall of the door bottom reinforced by two bars.
  • the motor vehicle door comprises an outer panel 1 (removed in Figure 1) and an inner panel of box 2 connected to each other at their lower part by a door bottom wall 3 extending transversely with respect to the two panels 1, 2.
  • said door bottom wall 3 is reinforced by a reinforcing element 4 fixed to this wall 3 and extending along a predominant part of the length and the width of this wall 3, covering the central area thereof.
  • This reinforcing element 4 consists, in this example, of a metal plate, for example of steel or aluminum, preferably having a greater thickness than that of the door bottom wall 3. As shown in FIGS. 2 and in particular FIG. 2, the reinforcing element 4 is a metal plate one of which 4a of the longitudinal edges is fixed, preferably by welding, against the inner face of the inner panel of caisson 2 and whose other longitudinal edge 4b is fixed in the same way against the inner face of the bottom wall of the door 3, near the outer panel 1.
  • the plate 4 forms an acute angle with the inner panel of box 2 and with the wall of the door bottom 3 and has, on each of its longitudinal edges, a folded edge parallel to the wall 2 or 3 to which it is fixed.
  • the plate 4 thus forms a bracket which reinforces the lower part of the door.
  • Figure 3 shows the deformation experienced by a side impact applied by a barrier 5 moving at a speed of the order of 60 km / h.
  • This barrier 5 moves above the sill box 6 of the vehicle and in particular above the rabbet 7 which is opposite the lower part 2a of the box wall 2 of the door.
  • the reinforcing element comprises two metal bars 8 fixed, by means of screws 9, against the outer face of the door bottom wall 3.
  • the bars 8 are fixed in a recess 10 embossed in the door bottom wall 3, so that the outer face 8a of the bars 8 is located substantially in the extension of the portion 3a of the door bottom wall 3 located outside the recess 10.
  • one 8b of the longitudinal edges of the bars 8 is located substantially in the extension of the lower portion 2a of the inner casing wall 2, so as to be located facing the lower part of the rabbet 7 formed in the body of the sill 6 of the vehicle, when the door is closed.
  • the longitudinal edge 8b of the bars 8 has a tip-shaped cross section 8c adapted to be able to sink into the adjacent rebate 7 of the rocker 6 in case of side impact on the door.
  • the lower part of the door comprises not only the reinforcing bars 8, but also the reinforcing plate 4 described with reference to FIGS. 1 to 3. The simultaneous presence of the reinforcing plate 4 and the bars 8 gives the lower part of the door an increased resistance against side impacts.
  • the double reinforcement above is particularly suitable for vehicles with two doors each having a relatively large length, that is to say, sensitive to side impacts, as in the case of coupes.
