Description

B e s c h r e i b u n

The invention relates to a motor vehicle door made of plastic in the preamble of the claim specified genus.

It will always be in power vehicle construction it is more common to remove certain parts of the vehicle body series made of plastic because it creates a Series νοη advantages is achieved, for example a lower total weight of the vehicle and the possibility of recycling these plastic parts, if replaced after a certain period of use Need to become.. .

In the case of motor vehicle doors made of plastic, however, the disadvantage often occurs that because of the required Bracing for the mutual fastening give way or the parts coming into contact with one another damage because the plastic is limited Has hardness, so that the attachment between these parts is inadequate and not secure enough.

In particular, this occurs when fastening by means common elements, such as bolts and nuts, between dom; inner structure cius plastic and the Hinge on the body post and also between = the inner structure and the lock of the door.

The invention is based on the object of designing a plastic door of the generic type in such a way that that these disadvantages are avoided ν where a simple, low-cost construction is to be made possible.

According to the invention, this object is achieved by that at the ends of the cross member atoei legs are formed with which the cross member via fastening means and with the interposition of the walls of the inner structure, which rest on the legs, on the one hand via the hinge of the door on one Post of the motor vehicle and on the other hand at the lock the door is attached.

The invention is explained below using an exemplary embodiment that is shown in the drawing is. Show it:

Figure 1 <- the view of a door and

FIG. 2 - an enlarged 3-sectional view. in the plane of line 1-Ί of the figure

The motor vehicle door shown schematically in FIG. 1 is denoted by 2. As Figure 2 shows, ' This an outer cladding 3 made of Kuns tstoff and an inner structure 4, which is also made of plastic consists. Both are to produce a unified

connected to each other. For this purpose are on inner structure 4 two flanges 6 and 8 formed by welding on the inside of the outer Cladding 3 are attached.

In that by the outer lining 3 and the inner Structure 4 formed space 10 is housed a cross member 11, which consists of metal and is adapted in shape to that of the inner structure 4, so that it is easily connected to this can be.

The cross member 11 has each at both ends. a leg 12 or 14, which is in surface contact with the opposite inside of the inner structure 4 is.

In the leg 1, a bore 16 is incorporated,. which is aligned with a bore 18 in the inner structure 4 and with a bore 20 a 3 hinge bracket 22 all three bores 16, 18 and 20 have the same diameter. The hinge bracket 22 is rotatable one end of a hinge bracket 24 mounted on a side post 26 of the body of the vehicle is attached.

The shaft is through the bores 16, 18 and 20 of a bolt 28 is inserted, a nut 30 on the threaded end of which protrudes into the space 10 is screwed on and thereby the cross member with the

inner structure 4 and the hinge bracket 22 braced.

Also in the leg 14 of the cross member 11 is a bore 32 machined, which is a bore 34 similar Diameter in the inner structure 4 and a bore 36 also of the same diameter in one Lock 38 corresponds to which cooperates with a bolt 40 which is attached to a center post 42 of the Body is attached.

A bolt is inserted through the bore 36 of the lock 38 44 inserted, which protrudes through the bores 34 and 32 into the interior 12 and on its thread a Nut 46 is screwed on. In this way is the Cross member 11 is also firmly connected on this side to the inner structure 4 and to the lock 38.

The connection of the lock 38 and the hinge bracket 22 to the door 2 is thus carried out in such a way that that the plastic walls of the inner structure 4 are clamped between metal parts, so that a adequate fastening is ensured.
