Description

[0001] The present invention relates to a motor vehicle door having the features of the preamble of patent claim 1 and a method for assembling such a motor vehicle door.

[0002] Motor vehicle doors with a door shell, an interior door panel, and a mirror triangle are known from the prior art. During the assembly of motor vehicle doors, the mirror triangle is first fixed to the door shell. The interior door panel is then attached to the door shell, so that the mirror triangle is centered and fixed to the door shell by means of the interior door panel.

[0003] When attaching the interior door panel to the door shell, the interior door panel frequently collides with the mirror triangle. This can cause damage to the mirror triangle.

[0004] From US 8 342 702 B2 a motor vehicle door according to the preamble of claim 1 is known.

[0005] Furthermore, JP H 07-186726 A indicates a motor vehicle door having the features of the preamble of claim 1.

[0006] Further state of the art on the technological background is known from JP H10- 58 979 A.

[0007] The object of the present invention is to provide a motor vehicle door that can be easily installed without damaging the individual elements of the motor vehicle door. Furthermore, the object of the present invention is to provide a method for installing such a motor vehicle door.

[0008] This object is achieved by the motor vehicle door having the features of patent claim 1 and the method for assembling such a motor vehicle door having the features of patent claim 7.

[0009] According to the invention, a motor vehicle door is provided which comprises a door shell, an inner door panel, and a mirror triangle that covers an area of the motor vehicle door to which an exterior mirror is attached. The inner door panel and the mirror triangle are fixed to the door shell, in particular detachably. The mirror triangle comprises at least two U-shaped recesses. The U-shaped recesses open downwards in the vertical direction of the motor vehicle door. The U-shaped recesses therefore extend from an underside of the mirror triangle upwards in the vertical direction of the motor vehicle door. The inner door panel comprises at least two pins. The pins are arranged in the U-shaped recesses such that the mirror triangle is secured against downward displacement in the vertical direction of the motor vehicle door.The mirror triangle is secured to the interior door panel by a locking element that prevents it from sliding upwards in the vertical direction of the vehicle door. In particular, the locking element secures the pins in the U-shaped recesses.

[0010] The core idea of the invention is to provide the mirror triangle with U-shaped recesses. This allows the mirror triangle to be easily slid onto the pins after the interior door panel is secured to the door shell. Using the locking element, the mirror triangle can then be easily secured to the interior door panel and thus to the door shell.

[0011] In the context of the present invention, the term door shell refers to the supporting structure of the motor vehicle door.

[0012] In an exemplary embodiment of the motor vehicle door according to the invention, the pins on the mirror triangle are located at the apex of the U-shaped recesses, ie at a highest point of the recess in the vertical direction of the motor vehicle door.

[0013] In a preferred embodiment of the motor vehicle door according to the invention, the mirror triangle comprises at least one projection. The projection is encompassed by the locking element in such a way that the mirror triangle and the locking element are secured in position relative to one another in the vertical direction of the motor vehicle door.

[0014] For example, the locking element, in particular with its upper side, rests against a lower side of at least one of the pins.

[0015] The locking element can engage around the projection laterally.

[0016] The projection can extend in the transverse direction of the motor vehicle door and / or the longitudinal direction of the motor vehicle door.

[0017] The locking element comprises, for example, two projections.

[0018] The projections can extend in different directions, particularly in the transverse direction of the motor vehicle door.

[0019] In a preferred embodiment of the motor vehicle door according to the invention, the mirror triangle comprises a guide element for guiding the locking element. The guide element at least partially encloses the locking element in the vertical direction and transverse direction of the motor vehicle door, so that the locking element is displaceably mounted relative to the mirror triangle in the longitudinal direction of the motor vehicle door.

[0020] The guide element thus prevents relative movement of the locking element in the vertical and transverse directions of the vehicle door, while allowing relative movement in the longitudinal direction of the vehicle door. Thus, the locking element can be moved from a release position, in which the mirror triangle can be moved in the vertical direction of the vehicle door, to a locking position, in which the mirror triangle is secured to the interior door panel, in particular to at least one of the pins of the interior door panel.

[0021] The locking element and the mirror triangle can together form an assembly which can be mounted on the door shell in one step.

[0022] In a preferred embodiment of the motor vehicle door according to the invention, the locking element is made of the same material as the mirror triangle.

[0023] The locking element can be made of a polyamide 6 (PA6), in particular of a 15 percent glass fiber reinforced polyamide 6 (PA6 GF 15).

[0024] In a preferred embodiment of the motor vehicle door according to the invention, the inner door panel can be secured, in particular via a suspension strip of the inner door panel at its upper end in the vertical direction of the motor vehicle door, to an element fixed to the door shell in such a way that the inner door panel can be pivoted about a pivot axis.

[0025] The pivot axis can extend in the longitudinal direction of the vehicle door.

[0026] The interior door panel can be arranged in such a way that a part of it, in particular the hanging strip, can be encompassed by the element fixed to the door shell.

[0027] For example, the element fixed to the door shell has a notch at the top end in the vertical direction of the vehicle door.

[0028] When cut in the transverse direction of the motor vehicle door, the notch can have a U-shaped profile that opens upwards in the vertical direction of the motor vehicle door. Furthermore, the present invention relates to a method for assembling a motor vehicle door, comprising the following steps: fixing an inner door panel to a door shell; sliding a mirror triangle, which comprises at least two U-shaped recesses that extend upwards from an underside of the mirror triangle in the vertical direction of the motor vehicle door, onto pins of the inner door panel such that the pins secure the mirror triangle against downward displacement in the vertical direction of the motor vehicle door; and securing the mirror triangle to the inner door panel against displacement in the vertical direction of the motor vehicle door by means of a locking element.

[0029] For example, the mirror triangle is pushed onto the pins of the interior door panel in such a way that the pins rest on the mirror triangle at the apex of the U-shaped recesses.

[0030] In an exemplary embodiment of the method according to the invention, the fixing of the inner door panel to the door shell comprises hanging the inner door panel at its upper end in the vertical direction of the motor vehicle door on an element fixed to the door shell and pivoting the inner door panel about a pivot axis extending, in particular, in the longitudinal direction of the motor vehicle door.

[0031] In the context of the present invention, the term “door shell fixed” describes an element that is firmly fixed to the door shell.

[0032] In a preferred embodiment of the method according to the invention, securing the mirror triangle to the door interior panel by means of the locking element comprises sliding the locking element onto at least one projection of the mirror triangle, wherein the locking element rests against an underside of at least one of the pins and laterally engages around the projection.

[0033] In an exemplary embodiment of the method according to the invention, securing the mirror triangle to the door interior panel by means of the locking element comprises displacing the locking element in the longitudinal direction of the motor vehicle door in such a way that the locking element rests against the underside of the pins.

[0034] The locking element can be arranged in a guide element of the mirror triangle.

[0035] The guide element encloses the locking element in the vertical direction of the motor vehicle door and the transverse direction of the motor vehicle door, for example at least partially, so that the locking element is displaceable in the longitudinal direction of the motor vehicle door and immovably mounted in the vertical direction of the motor vehicle door and the transverse direction of the motor vehicle door.

[0036] The invention is explained in more detail below using an exemplary embodiment illustrated in the drawing. It shows: Fig. 1 a side view of a motor vehicle door according to the invention; Fig. 2 a perspective view of a partial area of an interior door panel of the motor vehicle door according to the invention; Fig. 3 a side view of a mirror triangle of the motor vehicle door according to the invention; Fig. 4 a plan view of a locking element of the motor vehicle door according to the invention; Fig. 5 a side view of the locking element; Fig. 6 a side view of the mirror triangle and the locking element; Fig. 7 a sectional view along line VII - VII in Fig. 6; and Fig. 8 a sectional view along line VIII - VIII in Fig. 6.

[0037] In Fig. Figure 1 shows a portion of a motor vehicle door 2 according to the invention. The motor vehicle door 2 comprises a door shell 4, an interior door panel 6, a mirror triangle 8, a molded seal 30, and a locking element 14.

[0038] In order to fix the inner door panel 6 to the door shell 4, the inner door panel 6 is pivotably secured, in particular suspended, at its upper end in the vertical direction of the motor vehicle door to an element 22 fixed to the door shell about a pivot axis extending in the longitudinal direction of the motor vehicle door.

[0039] To secure the interior door panel 6, the element 22 fixed to the door body shell includes a notch on its upper side in the vertical direction of the vehicle door. Once the interior door panel 6 is secured to the element 22 fixed to the door body shell, a suspension strip of the interior door panel 6 is arranged at least partially in the notch.

[0040] Following the pivotable securing of the interior door panel 6 to the element fixed to the door shell, the interior door panel 6 is pivoted about the pivot axis in the direction of the door shell 4. The pivot axis extends along an upper edge of the element 22 fixed to the door shell. The element 22 fixed to the door shell is an interior window shaft seal.

[0041] As is particularly evident from Fig. 2, the inner door panel 6 comprises two pins 12 on its side facing the door shell 4. The pins 12 extend outwards in the transverse direction of the motor vehicle door, ie in the direction of the door shell 4.

[0042] The Fig. The mirror triangle 8 shown in isolation in Figure 3 comprises two U-shaped recesses 10 that correspond to the pins 12. The U-shaped recesses 10 are open downwards in the vertical direction of the vehicle door.

[0043] During assembly of the vehicle door 2, the mirror triangle 8 is pushed onto the pins 12 in such a way that the pins 12 secure the mirror triangle 8 against downward displacement in the vertical direction of the vehicle door. For this purpose, the mirror triangle 8 rests on the pins 12 at the apex points of the U-shaped recesses 10, i.e., at the highest points of the recesses 10 in the vertical direction of the vehicle door.

[0044] To ensure that the mirror triangle 8 cannot be removed from the pins 12 in the vertical direction of the vehicle door after it has been pushed on, the mirror triangle 8 is secured by means of a Fig. 4 and Fig. 5 shown locking element 14 is secured to the door inner panel 6 (see Fig. 6 to 8). For this purpose, the locking element 14 is pushed rearward in the longitudinal direction of the motor vehicle door into a recess in the door panel, which is adjacent to the mirror triangle 8.

[0045] The locking element 14 comprises a base plate 26, a cover 28, and lateral gripping elements 24. When the motor vehicle door 2 is mounted, the locking element 14, in particular the base plate 26 of the locking element 14, extends in the longitudinal direction of the motor vehicle door. The cover 28 adjoins the base plate 26 at its ends in the longitudinal direction of the motor vehicle door. The cover 28 is flush with a visible surface of the mirror triangle 8 and itself forms a visible surface for a vehicle occupant.

[0046] The gripping elements 24 are arranged laterally, i.e., in the transverse direction of the motor vehicle door, on the base plate 26, extend in the vertical direction of the motor vehicle door, and are C-shaped. The open sides of the C-shaped gripping elements 24 face each other.

[0047] As is particularly evident from Fig.As can be seen in Figure 3, the mirror triangle 8 comprises projections 18, 20 corresponding to the gripping elements 24. The projections 18, 20 extend in the transverse direction of the motor vehicle door and are laterally encompassed by a corresponding one of the gripping elements 24. In this case, the locking element 14, in particular the base plate 26 of the locking element 14, rests against the underside of at least one of the pins 12.
