DE102008032660A1 - Device for producing uniform transition region between roof lining and pillar lining in motor vehicle, has spring-resilient units working against indentation, where indentation is caused by assembly and/or manufacturing tolerances - Google Patents

Abstract

The device has spring-resilient units working against an indentation of a foam layer of a foam-padded lining part i.e. roof lining (1), where the indentation is caused by assembly and/or manufacturing tolerances. The foam-padded lining part is arranged in a roof area and provided with a lamination. The units are formed by a resilient foam padding arranged in a transition region. A lining part i.e. pillar lining (2), is arranged adjacent to the foam-padded lining part, where the lining part overlaps in the transition region.

Description

The The present invention relates to a device for producing uniform transition regions between a foam padded cowling and one on it subsequent Cowling in motor vehicles, especially between one arranged in the roof area, foam-padded mold sky and a adjacent pillar trim, which overlap in the transition area.

In conventional cladding of the generic type (see. 2 the attached drawing) arranged under the decor or the lamination foam upholstery are designed to protect the occupants against hard impacts in vehicle collisions, z. B. against head impacts in the roof-shaped sky. The upholstery foam, z. B. EPP, is designed so that it absorbs impact, in particular impact, so with corresponding internal damping.

Become such trim parts adjacent to each other and overlapping mounted, so can due to manufacturing tolerances and / or assembly processes in the joint area indentations arise, which do not regress and those in unfavorable make no smooth or aesthetic transition represent.

task The invention is based on the generic device to develop these with simple means in such a way that always gapless transitions between the trim parts are achievable.

These Task is according to the invention with the characterizing features of claim 1. advantageous Further developments of the invention are specified in the subclaims.

According to the invention, it is proposed that in the transition area resilient means are provided, the one through the Mounting and / or due to manufacturing tolerances indentation of Counteract foam padding of the paneling. This succeeds it, without impairment the on impact attenuation designed foam padding to create smooth transitional areas, the corresponding springback property exhibit.

The said means can advantageously by a arranged in the transition region, especially rebounding Foam insert may be formed, which is preferably applied below the lamination is.

The Means can Furthermore, manufacturing technology particularly favorable by one in the transition region glued in, additional Foam strips made of particularly springy foam or one consist of comparable material.

To furthermore, the overlapped Covering part in the transition area be provided with a gradation in which the means or the foam strip are arranged. this makes possible the creation of particularly aesthetic, Mostly in a uniform level transitions between the trim parts.

alternative can the lamination of the foam-padded paneling and the foam padding in the transition area not with the carrier material be glued, resulting in a limited extent a greater resilience property the foam padding in the transition area given is.

One embodiment The invention is described below with reference to the accompanying drawings explained in more detail. It demonstrate:

1 a rough schematic view of the vehicle interior on the partially illustrated mold sky and a trim part of the A-pillar of the motor vehicle with the overlapping transition region;

2 a section according to line II-II of 1 through the trim parts in the transition region, according to the prior art;

3 the same section according to line III-III of 1 with provided in the transition region, resilient foam padding.

The 1 shows roughly schematically as a first trim part attached to the roof of the motor vehicle in the interior, substantially flat and only partially visible mold sky 1 standing in a side area 1a to an elongated, adapted to an A-pillar of the body of the motor vehicle trim part 2 followed.

The shape sky 1 (see. 2 , Prior art) is at least in the side areas 1a with a plastic foam layer 3 upholstered on a support material 4 foamed. The foam layer 3 defined thickness is with a covering lamination or a decor 5 Mistake.

The trim part or the elongated pillar trim 2 is in accordance with the 2 and 3 made of a plastic plastic as a carrier material, with a rounded abutment area 2a provided and with a decorative material 7 overdrawn.

When installing the pillar trim 2 after assembled mold sky 1 becomes the pillar trim 2 put on the A-pillar, taking the side area 1a of the form sky 1 under impressions of the foam-padded decor 5 as in 2 apparently overlaps and the transition area shown 6 forms.

Production-related tolerances or assembly steps (eg adaptation to other adjacent components) may cause the trim parts already assembled in the assembly process 1 . 2 over the transition area 6 be moved against each other. This is the transition area 6 reduced, it is created by the indentation on the drawn Eindrückmaß a foam padding 3 a gap s or even s', which is due to the lack of resilience of designed for a favorable impact attenuation foam layer 3 established.

To ensure an always constant transition range 6 between the form sky 1 and the pillar trim 2 regardless of the existing tolerances and / or unfavorable assembly steps according to the invention in the overlap area and transition area at 6 resilient means in the form of a strong spring-back foam insert 8th arranged as it is from the 3 evident.

The foam insert 8th extends as shown (see closer hatching in the 3 ) over the entire overlap area of the trim parts 1 and 2 and in the form of sky 1 into it to a point where the wearer 4 of the form sky 1 in an inward, the vehicle interior parked gradation 4a passes.

The foam insert 8th optionally in one operation to the foam layer 3 be splashed and is also from the decor 5 covered or glued to this.

When installing the pillar trim 2 on the A-pillar with appropriate overlap of the trim parts 1a . 2 arises according to the 3 regardless of tolerances and mounting adjustments always the same transition range 6 , without it comes to the visually disadvantageous, permanently pressed on the Eindrückmaß a gap sections s, s'. Relative displacements of the trim part 2 are therefore without permanent indentations on the spring-back foam insert 8th balanced.

The foam insert 8th may deviate from the 3 also by a separately inserted foam strip 8th made of strong rebound material or a similar material and below the decor 5 be arranged.

In an alternative solution, if appropriate, the foam layer 3 in a manner known per se (cf. 2 ) be provided throughout. To achieve a better springback effect but the foam layer 3 with the decor 5 in the overlap area and transition area 6 not with the carrier material 4 glued, but is loosely attached to this. This results in a better distribution of the contact forces in the transition region with improved springback effect.

The Invention is not limited to the illustrated embodiment, but always usable when foam-padded trim parts with overlapping areas to be adjacent to each other.

This can any trim parts in the interior area, eg. B. also on door panels, etc. be of the motor vehicle.
