Description

The The invention relates to a motor vehicle with a sliding door and especially cars like mini-vans or vans with such doors.

motor vehicles In the state of approval must have certain safety regulations including the existence of diverse frontal and Side impact tests heard. Such safety regulations are either of regional origin (eg EuroNCAP for Europe) or are increasingly the result of international harmonization efforts.

The Global Technical Regulation no. 01, abbreviated to GTR1, the United Nations title "Door locks and door retention components", edition 1 of April 2005 describes in Appendix 4 a test existing from side doors intended to reflect the case of a passenger thrown against the inside of the sliding door. During the test, a force of 9 kN acting perpendicularly from the inside to the outside is initiated at two points of the sliding door at the door lock height, after which the door must not open. The member states of the United Nations are required to transpose the GTR1 into national legislation, so it can be assumed that in the future there will be states which will prescribe the test for new registrations mentioned in this document.

It is an object of an embodiment of the invention, a To provide motor vehicle with a sliding door, the the o. g. Rules of the GTR1 for door locks reliably fulfilled.

The Solution to this problem is the characteristics of the independent Claim. Advantageous developments and further embodiments result with the features of the dependent claims.

One The first aspect of the invention relates to a motor vehicle having a Sliding door. When the sliding door is closed is a part of the sliding door facing a B-pillar. The B-pillar facing part of the sliding door has a catch element and the B-pillar a catch element associated through hole, hereinafter referred to as the first through hole referred to as. Conversely, the B-pillar can also be a catch element and corresponding to said part of the sliding door, an associated one have first passage opening. The first through hole is associated with a reinforcing element, and the reinforcing element has a passage opening, subsequently second passage opening called, with a parked collar. When closed the sliding door is the catch element in the first and in retracted the second passage opening.

comes it in the above-described force from the inside to the Sliding door, so it may deform due to a shift Fangelements in the vehicle transverse direction and thus come relatively to the reinforcement. The catch element is here by the gain in his held in position in the collar area. The reinforcement with her collar therefore takes powers in the vehicle transverse direction, hinders a more extensive Deformation and thus complicates a deformation-induced opening the sliding door.

Farther With the reinforcement also the side impact protection the vehicle improved. Is in the event of a side impact in the area of the Fangelements initiated a force, then the sliding door over the catching element introduced into the first passage opening stabilized in the vehicle transverse direction or intrusions are reduced. In this respect, it plays for the following remarks It does not matter if there is a force in the B-pillar area from the inside is initiated to the outside or vice versa. It will be the Structural stability of the sliding door for a force inward and outward increases.

In A second embodiment is the first through hole introduced into the reinforcement B-pillar, wherein the edge of the through hole with a in the B-pillar protruding cage is connected.

at this embodiment is with the sliding door closed The catch element partially absorbed by the cage, with the reinforcement B-pillar and possibly the side wall connected outside of the B-pillar and welded as a rule is. If there is a shift of Fangelements relative to the first Through hole, so with the cage on acting on the edge of the first passage opening force distributed a larger area. This can be the Structure withstand greater forces and reduces the likelihood of unwanted opening the sliding door.

In Another embodiment is for the motor vehicle a cylindrical cage and a catch pin as a catch element intended. The geometry of the two parts is so simple and cost-effective to realize.

Further Embodiments provide that the reinforcing element with reinforcement B-pillar or with reinforcement Sidewall of the sliding door is connected. In this way the area of the first passage opening is maximally reinforced, namely, where the forces significantly attack.

In a further embodiment, the reinforcing element is designed as a plate of the surface of the collar protrudes vertically. The two-dimensional design, which is adapted to the contour of the mounting area, allows for easy welding of the panel with the B-pillar reinforcement or sliding door reinforcement, on the one hand, and reduces the local stress on the other, which reduces the risk of a material tear.

Farther may be provided as an embodiment that the catch element, z. B. the catch bolt, end hook-shaped is and with the sliding door over the Edge of the collar protrudes.

in the As a rule, the catch element, z. B. a catch bolt, obliquely be aligned to the vehicle transverse direction. Does it come to a force application after outside or inside and above to a relative displacement Reinforcement / catch element, this remains in particular even with a generously dimensioned collar diameter hang the hook-shaped end on the collar edge. During the deformation process Does it then pivot the Fangelements around the collar edge, without causing the catch element, z. As a catch bolt on the collar slides out of the cage. The hook-shaped Training and positioning of the catchment thus ensures Load case the relative position of the sliding door to the B-pillar.

exemplary Embodiments of the invention are described below With reference to the accompanying drawings. This is not the use of reference numerals in the figures be understood that the reference numerals the scope to restrict the claimed invention.

1 shows a motor vehicle sliding door in the perspective side view,

2 shows a section AA through the sliding door of the 1 .

3 the sectional area AA in the perspective side view,

4 , b the in 2 shown reinforcing element in plan view and in side view.

In the figures, which generally denote like objects with like reference numerals, shows 1 the sliding door 1 a motor vehicle, the side right (not shown) adjacent to a B pillar of the motor vehicle.

2 shows a horizontal section AA through the sliding door 1 of the 1 looking towards the in 1 drawn arrows, ie vertically downwards. 3 shows the corresponding in the perspective side view. You can see a part on the left 2 the sliding door 1 that is a B-pillar 3 is facing. The sliding door 1 has an outer panel 4 and a reinforcing sheet 5 ,

To record a Fangelements 6 is a welding nut 7 with the reinforcement plate 5 the sliding door 1 welded. The catch element 6 is a first passage opening 8th in the B-pillar 3 facing and functionally assigned. The first passage opening 8th goes through both the side wall B-pillar 9 as well as through the reinforcement B-pillar 10 the B-pillar 3 , When closing the sliding door 1 arrives the catch element 6 , in this case a catch bolt, in the in 2 shown closed position, ie penetrates into the first passage opening 8th and is then partially inside the B-pillar 3 ,

In a side impact in the vehicle transverse direction (= y direction) or generally from the outside, but also in a load from the inside to the outside (for example due to a slipping load in the vehicle interior), it can lead to a deformation of the mounting area of Fangelements 6 come. The x-direction in this case points in the vehicle longitudinal direction to the rear of the vehicle. This is indicated by the double arrow. For example, the force acts from the outside of the vehicle 11 in the direction of the vehicle interior 12 , so in 2 vertically upwards, so that is in the B-pillar 3 dipped head of the catch 6 largely fixed and pivots the sliding door side of the Fangelements 6 together with the weld nut, turn clockwise upwards. This attachment gives the sliding door more support and reduces intrusions into the vehicle interior 12 , The same applies mutatis mutandis, if the B-pillar 3 a projecting catch element 3 have and the first through hole 8th in the sliding door 1 would be introduced.

In the first through hole 8th is still a cylindrical cage 13 introduced, with his flange 14 with the side wall B-pillar 9 and possibly with the reinforcement B-pillar 10 is welded. This will put you on the edge of the first through hole 8th or to the reinforcement B-pillar 3 acting force distributed over a larger area. This rips the reinforcement B-pillar 10 not so easy and is fixed in the B-pillar end of the Fangelements in case of load more reliable. This reduces the likelihood of accidental opening of the sliding door 1 ,

Furthermore, in 2 the cage 13 in a reinforcing element 15 introduced. The reinforcing element 15 owns, cf. this the top view of 4a , a plate 16 at the welding points 17 with the reinforcement B-pillar 10 is welded. The first through hole 8th korrespondie rende passage opening 18 gets from one of the plate 16 protruding collar 19 educated. The collar 19 protrudes vertically from the plate 16 from, cf. For this 4b ,

When loading causes the collar 19 two. Once through the further reinforcement into the B-pillar 3 immersed end of Fangelements better fixed. Since this end also the end of the shape of a hook 20 has and this with closed sliding door 1 over the edge of the collar 19 protrudes, the catch element hooks 6 at its pivoting clockwise at the collar edge. Especially with larger diameter of the cage 13 This also prevents the catch element 6 along the inner collar edge out of the cage 13 slides out. Overall, this is the local fixation of Fangelements 6 improves and thus reduces intrusions into the vehicle interior. The same applies mutatis mutandis when the force acts from the inside out.

Even though concrete embodiments have been described above, The person skilled in the art will recognize that the description of these embodiments does not have the purpose to limit the invention in the form specified. Rather, the invention is intended to be all modifications, equivalents and include alternatives that are within the scope of the claimed claims Fall invention.
