Abstract

A motor vehicle door having a door inside part (19), a door outside part (20) and a supporting panel (3) which is connected in a tight-fitting manner to the door inside part (19). The supporting panel (3) is a structural part made of a reinforced plastic, extends essentially over the surface of the door and has an edge (30, 31, 32, 33) all the way around, a first frame plate (4) and a second frame plate (5) are connected to the edge of the supporting panel (3), said frame plates being folded profiles which extend along the vertical parts of the edge, the first limb (42, 55) being connected to the edge (30, 31) of the supporting panel (3), the door inside part (19) is a shell made of plastic with fitting surfaces (49, 83) to which the second limbs (43, 56) of the frame plates (4, 5) and the supporting panel (3) are fastened, and the door inside part (19) protrudes outward over the supporting panel (3) and forms a connecting flange (50, 63), the door outside part (20) is a skin which is fastened to the connecting flange (50, 63) by means of a fastener (59).

Claims

1. Motor vehicle door, comprising a door inside part, a door outside part and a supporting panel which is connected in a tight-fitting manner to the door inside part, wherein

a) the supporting panel, (3) is a structural part consisting of a reinforced plastic, extends essentially over a surface of the door and has an edge (30, 31, 32, 33) all the way around,

b) a first frame plate (4) and a second frame plate (5) are connected to the edge of the supporting panel (3), said frame plates being folded profiles which extend along vertical parts of the edge and each having a first limb (42, 55) of which is directed parallel to the surface of the door (1) and a second limb (43, 56) of which is directed transversely to the surface of the door (1), the first limbs (42, 55) being connected to the edge (30, 31) of the supporting panel (3),

c) the door inside part (19) is a shell consisting of plastic with first fitting surfaces (49′

) to which the second limbs (43, 56) of the first and second frame plates (4, 5) are fastened, at least over part of its length, and with a second fitting surface (83) to which the supporting panel (3) is fastened, and wherein the door inside part (19) forms shell parts (49) protruding outward over the supporting panel (3), and a connecting flange (50, 63),

d) the door outside part (20) is a skin which is fastened to the connecting flange (50, 63) by means of positive fastening means (59).

2. The motor vehicle door as claimed in claim 1, wherein the first frame plate (4) is connected to hinges (6, 7) and the second frame plate (5) is connected to a door lock (9).

3. The motor vehicle door as claimed in claim 1, wherein a collision protection support (13) is fastened by its ends to the first and second frame plates (4, 5) outside the supporting panel (3).

4. The motor vehicle door as claimed in claim 3, wherein the profile of the first and second frame plates (4, 5) has, at least in part, a third limb (44, 57) which is approximately parallel to the first limb (42, 55) and is outside the latter.

5. The motor vehicle door as claimed in claim 4, wherein a collision protection support (13) is fastened to the third limb (44, 57).

6. The motor vehicle door as claimed in claim 5, wherein the first and second frame plates (4, 5) extend essentially as far as the upper edge (33) of the supporting panel (3), and wherein a separate window frame (2) is placed on an upper edge (33) of the supporting panel (3) and is fastened to the first limb (42, 55) and to the third limb (45, 57) of the profile.

7. The motor vehicle door as claimed in claim 1, wherein the supporting panel (3) comprises an inner wall and an outer wall consisting of fiber-reinforced plastic, which walls are connected to each other at least along the edge (30, 31, 32, 33) and cavities are formed between the walls.

8. The motor vehicle door as claimed in claim 7, wherein the supporting panel (3) has an aperture (40) which forms an inner edge and at which its walls are connected to each other.

9. The motor vehicle door as claimed in claim 1, wherein the supporting panel (3) has integrated metallic inserts (35, 36, 39) for fastening means (38, 45).

10. The motor vehicle door as claimed in claim 8, wherein the supporting panel (3) bears window guides (12) on a side facing the door outside part.

11. The motor vehicle door as claimed in claim 1, wherein the door inside part (19) has sockets on its surface facing the vehicle interior, for the attachment of insert parts.

12. The motor vehicle door as claimed in claim 1, wherein the door inside part (19) has, in its upper edge zone(90), a window seal (92) and plug-in elements (91) with which it is placed vertically onto the supporting panel (3).

13. The motor vehicle door as claimed in claim 1, wherein the door inside part (19) has a peripheral rubber seal (81) which bears against the supporting panel (3).

14. The motor vehicle door as claimed in claim 13, wherein cabling is pre-assembled on the inside of the door inside part (19).
