Method for creating a 3D effect seat complex and associated seat

Abstract

A method is intended to produce a seat complex (CS). The method comprises the following steps: (i) securing together an upper underlay (ES) and a lower underlay (EI), which are to form part of a seat complex (CS), by making two longitudinal seams (CLB) along two respective longitudinal edges (BL), and at least one longitudinal seam (CLI), comprising, at at least one chosen point, a kink (DC) pointing toward a transverse zone, in an intermediate part (PI) situated between the two longitudinal edges (BL) so as to define at least two longitudinal housings (LL) between the lower underlay (EI) and the upper underlay (ES), (ii) installing a deformable strip (BD) in each longitudinal housing (LL), (iii) securing together the lower underlay (EI) and upper underlay (ES) by making in each transverse zone a transverse seam (CT1) that passes through a corresponding kink (DC), by folding an excess of upper underlay (ES) brought about by the presence of this kink (DC) onto itself in order, within each longitudinal housing, (LL) to define sub-parts (SP) containing parts of the corresponding deformable strip (BD), and (iv) securing together the lower underlay (EI) and upper underlay (ES) by making two transverse seams (CT2) along two respective transverse edges (BT) in order to finish making the seat complex (CS).

Description

Technical field [0001] The present invention relates to a seat, and more specifically to the realization of a skin outer cover composite part included in certain seats. Background technique [0002] Here, a “composite” can be understood as a component or a component of components that are connected to each other as a whole, and is used to form a part of the seat back or the seat cover of the seat, usually the central part. Such composites are often used to cover vehicle (and motor vehicle if necessary) seats (albeit non-limiting). [0003] As those skilled in the art know, in order to realize a seat composite including a “pattern”, various methods (or methods) have been proposed. [0004] Here, “pattern” can be understood as the definition of the shape by the stitching part, and the shape is usually a geometric shape (for example, rectangular or square). [0005] Therefore, it has been proposed to connect a plurality of small pads having a generally rectangular or square shape, for e...

Problems solved by technology

[0008] Each of these methods (or approaches) has at least one disadvantage

In fact, manual operations must be performed entirely by one or more persons and / or consume a large amount of padding, which makes the composite so expensive that it allows manufacturing, and / or does not allow to obtain a three-dimensional effect (either 3D or volumetric) composites, which especially limits the stylistic effects of these composites
