The invention relates to an attachment device for a handle for the passenger compartment of a motor vehicle in the region of the inside of a vehicle roof. The fixing device supports the roof lining and includes a basic carrier element of the handle, which is provided with protrusions which can be latched in cutouts of the body panel, and at least one push-in blocking element in the handle, which serves for latching the basic carrier element of the handle.
Various attachment devices for a handle for the passenger compartment, for example, of a motor vehicle are known in practice. Typically, depending on whether the vehicle is or is not fitted with an airbag integrated in the roof lining, the attachment device may bridge different spacings. On the one hand, in the case of an application without an integrated airbag, the roof lining usually butts against the body structure, whereas, in the case of an application with an airbag integrated in the roof lining, the attachment device, as a result of the roof-lining contour curving in the direction of the interior, bridges a spacing of, for example, approximately 28 mm.
In the case of the application without an airbag integrated in the roof lining, it is generally known from practice for the attachment device, which also secures the roof lining, essentially to comprise a basic carrier element of the handle, the basic carrier element being provided with protrusions which can be latched in cutouts of the body panel. The latching of the attachment device can take place here, for example, by virtue of a blocking element, e.g. a blocking finger, which is prefitted in the basic carrier element of the handle.
In the case of the application with an airbag integrated in the roof lining, it is generally known from practice for a spacing of, for example, 28 mm, which typically arises, due to the presence of an airbag, as a result of the roof-lining contour curving in the direction of the interior, to be bridged by a different attachment element, which is suitable for fitting a handle in the region of the inside of a vehicle roof with an airbag integrated in the roof lining, this fixing element likewise bearing the roof lining at the same time.
These two different attachment devices for the application without an airbag integrated in the roof lining and the application with an airbag integrated in the roof lining are accompanied by the disadvantage that these two attachment devices usually have to be configured using different individual parts, which often requires an additional outlay from a production and an installation perspective.
One object of an embodiment of the invention is to improve or develop further the known attachment devices, while maintaining the previous advantages, so as to allow fixing of the handles for applications without an airbag integrated in the roof lining and for applications with an airbag integrated in the roof lining using the same parts for both applications. The desired attachment device here is intended to be capable of being produced straightforwardly and cost-effectively and, in addition, the desired attachment device is intended to be straightforward to handle and easy to install.
According to one embodiment of the invention, the attachment device “fixes” or attaches a handle and the roof lining, with or without an airbag integrated therein, in the region of the inside of the vehicle roof, and has an adapter element which can be inserted into a basic carrier element between the handle and the body panel. The adapter element being designed for accommodating a subregion of the blocking element for latching purposes. The adapter element thus makes it possible, by straightforward means, to allow optional fixing of the handles for applications without an airbag integrated in the roof lining and applications with an airbag integrated in the roof lining using the same parts for both applications. The fixing system for the basic carrier element on the body panel and the blocking element on the basic carrier element of the first application is transferred in each case to the adapter element of the second application so that the same parts can be used for both applications. For applications with an integrated airbag, the adapter element may be interposed such that the adapter element can be inserted into the basic carrier element between the handle and the body panel. This adapter element may be in operative connection with the basic carrier element and the blocking element by use of a latching connection so that the entire unit may be latched in the body panel. Both latching connections are secured by pushing in the blocking element.
According to an embodiment of the present invention, the basic carrier element with at least one blocking element and the basic carrier element with the adapter element inserted and at least one blocking element are designed as preassembled structural units, intended to simplify installation yet further. It is expediently possibly, for further simplification, for the basic carrier element with at least one blocking element and the basic carrier element with the adapter element inserted and at least one blocking element to be designed as structural units which are preassembled with one another and/or are prefitted on the roof lining. Furthermore, it may be provided that the adapter element is designed to be prefitted on the roof lining.
According to an alternative embodiment, the basic carrier element with at least one blocking element and the basic carrier element with the adapter element inserted and at least one blocking element are designed as separate structural units.
According to a further embodiment of the present invention, the basic carrier element of the attachment device has, on one side, a horizontally and a vertically running stop for the roof lining. The basic carrier element may have on the side of the horizontally and vertically running stops, above and adjacent to the vertically running stop, a stop notch for the body panel. It is expedient, moreover, if the basic carrier element has on the side of the horizontally and vertically running stops, in the region beneath the horizontally running stop, an aperture for accommodating a latching element of the adapter element, with a stop arranged in the region of the underside thereof. The adapter element can thus be inserted straightforwardly and securely in the basic carrier element.
According to a further embodiment, the basic carrier element has on the underside, on the side of the horizontally and vertically running stops, an aperture which runs obliquely inward in the direction of the roof lining and serves for accommodating a sheet-like reinforcing element of the handle.
Furthermore, the basic carrier element may have, in its central region, an aperture for the through-passage of the blocking element and for accommodating the same. The basic carrier element includes, on the side which is located opposite the first stop notch for the body panel in relation to the aperture for the blocking element, a second stop notch for the body panel. The basic carrier element preferably has, above the first stop notch and the second stop notch for the body panel, in each case one latching element, in particular in each case one latching nose, these two latching elements being designed such that they can be forced apart from one another. The aperture of the basic carrier element for the blocking element includes on the inside, in order to interact with this blocking element for the purpose of forcing the two latching elements apart from one another, two stop surfaces which run obliquely inward in each case and are offset in relation to one another.
The basic carrier element is also shown to include, on the side of the second stop notch for the body panel, in the region of the transverse sides of the aperture for the blocking element, apertures for accommodating two further latching elements arranged on the longitudinal sides of the adapter element.
According to a further embodiment, the basic carrier element has, on the side which is located opposite the side of the horizontally and vertically running stops, a further vertically running stop for the roof lining. The basic carrier element also includes on the opposite side, adjacent to the vertically running stop, a horizontally running stop for the body panel or for a corresponding mating stop of the adapter element inserted.
Moreover, if the basic carrier element, which may be configured in one piece, has on the opposite side, at the bottom end of the latching element located on this side, a stop nose, and if, in order to interact with this stop nose, a corresponding mating stop may be provided on the basic carrier element, beneath the inner end of the horizontally running stop.
According to a further embodiment, the basic carrier element may include on each side, in the central region of the transverse sides of the aperture for the blocking element, in each case one cutout for accommodating two latching elements arranged on the longitudinal sides of the blocking element.
According to a further embodiment of the present invention, the adapter element has, on one end side, a latching element for the through-passage through the corresponding aperture of the basic carrier element. The adapter element may include on its longitudinal sides, adjacent to its second end side, in each case one latching element for the through-passage through the apertures of the basic carrier element which are provided for this purpose. The adapter element has here on the underside, adjacent to its second end side and alongside the latching elements, a stop which mates with the horizontally running stop of the basic carrier element.
According to a further embodiment, the adapter element has on each side, at its top end region, a horizontally running stop for the body panel. In this case, the adapter element has on each side, above and adjacent to the horizontally running stops for the body panel, a stop notch for the body panel.
The adapter element may have, in its central region, an aperture for the through-passage of the blocking element and for accommodating the same, this aperture essentially comprising vertically running stop guides for the blocking element. The adapter element here preferably has, above the two stop notches for the body panel, in each case one latching element, in particular in each case one latching nose, these two latching elements being designed such that they can be forced apart from one another. The adapter element preferably includes a stop at the bottom end of the latching element located in the direction of its second end side and, in order to interact with this stop, for a corresponding mating stop to provided at the inner end of the horizontally running stop located on this side of the adapter element for the body panel.
According to a further embodiment, the latching elements of the basic carrier element and the latching elements of the adapter element are designed with essentially equal dimensions, so that production is simplified and installation is facilitated since, for example, a drillhole of the same size is provided in the body panel in each case in order for the basic carrier element and the adapter element to be fitted there.
According to a further embodiment, the blocking element has an essentially elongate configuration for through-passage through the basic carrier element alone or through the basic carrier element and the adapter element. The blocking element includes, in its bottom subregion, two mating stop surfaces for the corresponding stop surfaces of the basic carrier element, the mating stop surfaces running obliquely inward in each case and being offset in relation to one another. Furthermore, the blocking element has in its top subregion, on its inner side in the inserted state, an obliquely inwardly running mating stop in order to allow the latching element to spring back resiliently. The blocking element here is shown to include a wedge-shaped design at its top end.
According to a further embodiment, the blocking element has in its bottom subregion, on each side and located approximately centrally, in each case one latching element for engaging in the cutouts of the basic carrier element.
According to a further embodiment, the blocking element has on both sides, in the region of its stem, in each case one latching element for interacting with mating latching elements, which are formed on the basic carrier element, in the preassembled state, so that the latching elements counteract a situation where a blocking element is drawn out in the downward direction.

The attachment device 10 for a handle, using the adapter element 17 makes it possible by straightforward means, to allow optional fixing of the handles for the applications without an airbag integrated in the roof lining 11 and the applications with an airbag integrated in the roof lining 11 using the same parts for both applications.

Accordingly, in applications with an integrated airbag, the adapter element 17 may to be interposed such that the adapter element 17 can be inserted into the basic carrier element 12 between the handle and the body panel 13. This adapter element 17 may be in operative connection with the basic carrier element 12 and the blocking element 16 by use of a latching connection, it being possible for the entire unit to be latched in the body panel 13. Both latching devices are secured by pushing in the blocking element 16.
As has already been mentioned, the embodiments illustrated are only examples of ways of realizing the invention. The latter is not restricted thereto; rather, a number of further modifications and refinements are possible. Thus, in particular, variations in respect of the design of the adapter element 17 and of the basic carrier element 12 and also of the blocking element 16 are conceivable. Provision is also made for the invention to be used for configurations of roof linings 11 and body panels 13 which differ from the refinements illustrated.
