Multiple-Part Surface Covering for the Cladding of Support Structures and Cladding Part

Abstract

A multiple-part surface covering for the cladding of support structures includes at least two surface covering parts, respective portion of a first and second surface covering parts, and a cover. The at least two surface covering parts are sewn to one another by way of a connecting seam. The respective portion of a first surface covering part and a respective portion of a second surface covering part form a seam overhang. The cover is sewn to the two surface covering parts by way of the connecting seam and covers the seam overhang. An edge strip core is arranged between the cover and the seam overhang.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] FIG. 1 shows a perspective view of an exemplary support part;

[0018] FIG. 2 shows a cross section through a surface covering; and

[0019] FIG. 3 shows another cross section through a surface covering.

DETAILED DESCRIPTION

[0020] FIG. 1 shows, by way of example, an instrument panel support 10, which is to serve as support structure 10 for the purpose of explaining the disclosure. As an alternative to the instrument panel support illustrated, all of the cladding parts located in the interior, such as glove boxes, central arm rests, central consoles, panels, armrests in the door claddings, door claddings, roof liners, rear consoles, pillar claddings etc. may also serve as support structure 10. This instrument panel support 10 has a surface 10o, which is to be laminated by means of a surface covering 12. As is illustrated in FIG. 1, this surface 10o may concern merely a portion, such as for example the surface in the upper region of the binnacle of what is known as the instrument cluster. The surface 10o to be laminated may, however, also be that part of the surface of the support part 10 that would be visible to an occupant of the vehicle in the interior space of the vehicle. As a further alternative, the surface 10o may also comprise the entire surface of the support part 10, wherein in that case regions of the support part 10 that are not visible to an occupant of the vehicle would also be laminated.

[0021] FIG. 2 shows a first embodiment of a multiple-part surface covering 20. The latter comprises two surface covering parts 21 and 22. Those sub-regions of the surface covering parts 21 and 22 that are illustrated horizontally in the figures form a planar cover of the support structure 10 from FIG. 1. The portions 21u and 22u of the surface covering parts are angled away and are illustrated in a perpendicular alignment in the figures. These portions 21u and 22u form a seam overhang. An edge strip core 25 is arranged on the end faces of the portions 21u and 22u forming the seam overhang or on the end face of the seam overhang. A portion of the circumferential surface of the edge strip core 25 is in touching contact with the end face of the seam overhang. A cover 24 is provided to fasten the edge strip core 25 to the seam overhang. The cover loops around the edge strip core 25, the cover coming into touching contact with a portion of the outer circumferential face of the edge strip core 25. The cover 24 may be in the form of a band, for example. The connecting seam 23 comprises a thread or a cord or the like and connects the cover 24 to the surface covering in the region of the parts 21u and 22u. In cross section, the cover has a sack-shaped form in which the edge strip core 25 is arranged. This assembly of seam overhang, edge strip core 25 and cover 24 forms, with a groove 11 located in the support structure 10, a type of tongue and groove connection. By pressing the seam overhang into the groove 11, the edge strip core is elastically deformed and clamped in between the walls of the groove 11. This makes it possible for the surface covering 20 to be pre-fixed on the support structure 10 in a particularly simple manner. In a subsequent step, the surface covering 20 is laminated onto the support structure 10, for example by activating an adhesive located between the surface covering 20 and the support structure 10.

[0022] A further alternative embodiment is illustrated in FIG. 3, with reference signs that are the same as those in FIG. 2 referring to identical components. By contrast to the embodiment in FIG. 2, the surfaces of the portions 21u and 22u do not lie against one another fully and are therefore not fully in touching contact in the region of the seam overhang. In the figures, above the seam 23, the surfaces 210 and 22o of the surface covering parts lie against one another and touch one another.

[0023] Below the connecting seam 23, the portions 21u and 22u form an acute angle with one another. This produces a free space between the portions 21u and 22u. The edge strip core 25 is arranged such that it penetrates this free space at least in certain portions. In this respect, a portion of the circumferential lateral face of the edge strip core 25 touches the surface 210 in the region of the portion 21u and the surface 22o in the region of the portion 22u. By comparison with the first embodiment, the height of the projecting region with the cover 24 is therefore lower. By contrast to this, however, the width is thicker. This affords the advantage that grooves with a shallower depth in the support structure 10 can be used, the result of which is a smaller overall structure of the interior cladding part as a whole. At the same time, the same advantage of the pre-fixability of the surface covering 20 to an underlying support structure 10 remains.
