The same reference numerals in the figures designate the same or equivalent elements.

Fig. 1 shows a mounting bracket 1 for a determination of a handle plate with a handle with hinged thereto handle.

The Montagearretierung has an actuating extension 13, in the form of a hook, by means of which the Montagearretierung can be activated.

Furthermore, two Verrastungsfortsätze 14 are provided on the Montagearretierung, which engages behind the lock plate and after locking the mounting arrest in a locking position of the handle plate. The right-hand latching process in the image is bent into the image plane, while the left-hand latching process in the image is bent out of the image plane.

For blocking an actuating lever, a locking device 11 is integrally formed on the mounting catch 1, which cooperates with a locking counterpart (51) on the actuating lever (5), wherein the locking device 11 is bent in an L-shape facing the viewer out of the image plane.

The determination of the handle plate and the handle shell is effected by the integrally formed on the Montagearretierung two locking devices 12, which cooperate with T-shaped pin on the handle shell. Since the Montagearretierung is mounted on the handle plate, the handle shell and the handle plate is so securely connected. The locking device has in each case two fixing extensions 121.

Fig. 2 shows the mounting stop 1 Fig. 1 when installed in a preassembled handle plate 2.

The Montageearretierung 1 is guided on the handle plate 2 in guides 21, which allow a linear movement corresponding to the image plane down.

The rotatably mounted about the abutment axis 53 actuating lever 5 is biased against a spring tension, counterclockwise, and held in this position by the locking device 11, which forms a positive connection with two formations from the operating lever 5 as locking counterparts 51.

The operating lever 5 directs a deflection about its abutment axis 53, which it experiences by a protruding through the boom opening 23 after final assembly boom (41) on a Bowden cable 7, which emits the force to a door lock mechanism, not shown.

A fully assembled door handle assembly 6 is in the 3 and 4 shown. Fig. 3 shows a door handle assembly 6 from above in a plan view. The grip 3, with it on a bearing axis 42 mounted handle 4 is through the Montagearretierung (not shown in this illustration) connected to the handle plate 2. Fig. 4 shows the assembled door handle assembly 6 from the side in another plan view.

The assembly of handle plate and handle shell, with unlocking the mounted on the handle plate operating lever is in the FIGS. 5 and 6 shown in more detail.

Fig. 5 shows again the preassembled handle plate Fig. 2 , The Montageearretierung 1 is in the mounting position M, the actuating lever 5 is blocked by the locking device 11, and the locking counterparts 51 in the counter-clockwise biased position, so that the boom opening 23 is largely openly accessible.

The extension openings 22 are also in the mounting position M of Montagearretierung 1 open, so that there later the extensions 31 of the handle shell 3 can be inserted through and fixed (see later Fig. 6 ).

The latching extensions 14 are not yet locked behind a projection.

Fig. 6 shows the state after assembly with a handle shell 3 after the Montagearretierung 1 has been pulled from the mounting position M in the locking position A. The locking device 3 is concealed by the handle plate 2. The locking means 12 of the Montagearretierung 1 locks the extensions 31 of the handle shell, which are formed by cross-sectionally T-shaped pin 32 and project through the extension openings.

The extensions 31 are fixed in the locking position A of the mounting catch 1 by the fixing projections 121 of the two locking devices 12.

The fixing projections 121 are bent out of the plane of Montageearretierung, creating a reliable and play-free connection of handle shell and handle plate by their elastic property.

By the movement of the Montagearretierung 1 in the locking position A and the locking device 11 is no longer engaged with the locking counterparts 51, which has released the operating lever 5 as a result. As a result, this could now perform the partial rotation D to the abutment 53, and come with its sliding surface 52 in contact with the boom 41 of the handle. The actuating lever 5 is mechanically biased against the boom 41. A deflection of the arm 41 downwards - by a line on the handle on the handle shell - causes a deflection of the operating lever 5 counterclockwise, which has a pull on the soul of the Bowden cable with appropriate power transmission to the door lock result.

In Arretierungsstellung A Montagearretierung 1 has been pulled out so far that now the Verrastungsfortsätze 14 are latched behind the edge 24 of the handle plate 2. The Montageearretierung 1 is brought safely in the mounting position M, without that an unintentional release of the handle and handle plate can occur.

In a further embodiment of the handle plate 2 according to Fig. 7 this is equipped with a locking lever 15 which can secure the mounting catch 1 in the mounting position against unwanted displacement in the direction of locking position A before assembly with the handle shell. The arranged in the region of an extension opening locking lever 15 is mounted horizontally to the edge 24 of the handle plate 2 pivotally mounted on an axis 16 and spring-loaded via a leg spring 17 in a clockwise direction. Further, the lock lever 15 at its one end via a projection 151 which engages behind a cam 18 of the Montagearretierung 1 positively, so that the Montagearretierung 1 can be prevented from displacement into the locking position. In addition, a stop surface 152 is integrally formed on the locking lever 15 in the region of the extension opening, which occurs during assembly of the handle plate 2 and handle shell with an extension of the handle in interaction. The locking lever 15 has been displaced so far in the course of this assembly by inserting the extension 31 in the extension opening via its stop surface 152 counterclockwise that the projection 151 of the locking lever 15, the cam 18 no longer engages behind. In this position, the locking lever 15, the Montageearretierung 1 could be pulled freely from the mounting position in the locking position A.

The Fig. 8 to Fig. 13 show in individual steps in schematic cross-sectional representations of an assembly of a handle with handle mounted thereon on a handle shell to illustrate once again the operation of the installation.

Fig. 8 shows the mounted on the inside 61a of the door panel 61 of the vehicle door 62 handle plate 2. The mounting catch 1 is in the mounting position, the operating lever 5 is therefore locked so that the boom opening 23 is free.

In the following FIG. 9 to FIG. 12 the introduction of the handle 3 in the handle plate 2 and thus the boom 41 in the boom opening 23 is shown. Since the handle shell 3 with the handle 4 is a preassembled part, the pivoting of the later occupied by the operating lever 5 space (see Fig. 13 ) needed to use the handle shell with handle can.

Is the handle 3 with the handle 4 and the boom 41 properly inserted (see Fig. 12 ) so can the Montagearretierung 1 are pulled, so are brought from the mounting position shown M in the locking position.

Fig. 13 shows the mounted state of the door handle assembly 6 together with a fixed grip 2 and handle plate 3 and released and therefore on the boom 41 fitting actuating lever 5. The Montagearretierung is in the locking position A.

Thus, a quick and easy assembly of prefabricated parts of a door handle assembly of a motor vehicle is possible, which simplifies the final assembly and makes more cost-effective, since otherwise customary sub-assemblies omitted and work steps are saved.
