Abstract

In a method for mounting an inner cover section to a support structure of a motor vehicle, an engagement member is introduced onto the cover section or onto the support structure and engages into a receptacle formed in the corresponding other component. The engagement member thereby seats loosely with play in the receptacle to engage behind it and a resilient device is provided between the cover section and the support structure to tension these components. The resilient device can be formed by an elastic foam material which at least partially fills-up the intermediate space between the cover section and the support structure.

Description

This application is a continuation of Ser. No. 09/264,715 filed Mar. 9, 1999 and claims Paris Convention priority of German utility model application number 298 04 637.7 filed Mar. 14, 1998 the complete disclosure of which are hereby incorporated by reference.[0001]

BACKGROUND OF THE INVENTION

The invention concerns a method for mounting an inside cover section on a support structure of a motor vehicle, wherein an engagement member is introduced onto the cover section or onto the support structure which engages into a receptacle formed in a corresponding other component.

The economical manufacture of a motor vehicle requires, among other things, that the relatively large number of inside cover sections be mounted in a simple, rapid, and reliable fashion. With conventional mounting devices, a spring clamp is introduced onto the cover member which engages into a retention eyelet disposed on the support structure and, in particular, into a sheet metal component. Deformation of the spring clamps provides compensation for dimensional tolerances occurring during manufacture as well as for various shrinkage manifestations of the components to be mounted. It has however turned out that only relatively small dimensional tolerances can be compensated for in this fashion so that there are stringent requirements concerning the dimensional precision of the inside cover sections. This is, however, disadvantageous and expensive from a manufacturing point of view.

It is therefore the underlying purpose of the invention to create a method for mounting an inner cover section of a motor vehicle which facilitates an economical mounting of the cover section while permitting compensation for large dimensional deviations.

SUMMARY OF THE INVENTION

This purpose is achieved in a method of the above mentioned kind in that the engagement member engages loosely and with play into the receptacle to engage behind same and a resilient device is provided for between the cover section and the support structure which tensions these components.

The loose engagement between the cover section and the support structure permits acceptance of large dimensional deviations in a simple manner during assembly of the cover section. One single fixed bearing point is thereby normally provided for between the cover section and the support structure. Since the engagement member engages behind the receptacle, the cover section can be introduced onto the support structure such that it cannot be pulled-off. The resilient device is provided between the cover section and the support structure to tension these two components in their assembled state and thereby holds them with respect to each other so that the cover section is fixed relative to the support structure. It has turned out that not only very rapid assembly times can be thereby achieved but good adjustment to dimensional deviations as well as the possibility of correction and compensation of the overall assembled position are also facilitated.

In preferred embodiments of the invention, the resilient device is formed from an elastic foam material disposed in the intermediate space between the cover section and the support structure and at least partially filling this space which pushes the two components away from each other to thereby securely tension same.

The engaging member is preferentially prefabricated separately and subsequently introduced onto the cover section or the support structure. Towards this end, same has a base section with which it e.g. is snapped into a corresponding opening. An engagement shoe is spaced from the base section by a brace and engages behind and within an opening in the receptacle. Introduction of the engagement shoe into the opening of the receptacle is simplified when the engagement shoe is tapered at its leading end and/or is directed away from the base member at this introductory end.

The receptacle can also be made from a separate prefabricated retention member which can be introduced onto the cover section or the support structure. In preferred embodiments, the engagement member is attached to the support structure and the receptacle is formed on the cover section. It is however also possible to form the engagement member on the cover member and to allow same to directly engage into an opening in the sheet metal chassis of the motor vehicle.

Further details and features of the invention can be extracted from the subsequent description of an embodiment with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWING

FIG. 1 shows a perspective view of a retention member, [0011]
FIG. 2 shows a perspective view of an engagement member, and [0012]
FIG. 3 shows a sectional plan view of a cover section mounted using the mounting device.[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 shows a [0014] retention member 11 made from plastic forming a receptacle 10 for an engagement member 15 shown in FIG. 2. Towards this end, the retention member 11 has a vertically accessible opening 12 which has a slot 13 on its outer side extending from the upper edge vertically in a downward direction. The retention member 11 can be introduced onto an inner cover section 20 via mounting points 14 as shown in FIG. 3.
The [0015] engagement member 15 comprises a base section 16 having engagement fingers 17 formed on its back side with which the engagement member 15 can be snapped into a corresponding opening in the support structure 21, as schematically indicated in FIG. 3.
A perpendicularly protruding [0016] brace 19 is formed on the side of the base member 16 facing away from the engagement fingers 17 and supports an engagement shoe 18 on its front which extends transverse thereto. The engagement shoe 18 is tapered at its lower lead end 18 a and is slightly bent away from the base member 16 at this location.
In order to mount the [0017] cover section 20 to the support structure 21, the engagement shoe 18 is introduced from an upward direction into the opening 12 of the retention member 11, wherein the brace 19 seats in the slot 13. Since the brace 19 is substantially thinner than the width of the slot 13 and since the engagement shoe 18 is thinner than the depth of the opening 12, the engagement shoe 18 engages only loosely and with substantial play in the opening 12 but however cannot be pulled-off at right angles to the insertion direction, e.g. outwardly, since the engagement shoe 18 is wider than the slot 13.
In order to fix the [0018] cover section 20 relative to the support structure 21, a resilient device 22 is disposed in the intermediate space 23 between the cover section 20 and the support structure 21, as schematically indicated in FIG. 3, which can be an elastic foam at least partially filling the intermediate space 23.
