Method for producing seat composite part with 3D effect and related 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 an implementation of a skin cover composite that some seats include. Background technique [0002] A "composite part" is to be understood here as an assembly of elements or components which are integrally connected to one another and which are intended to form part of the leather cover of a seat back or seat seat, usually a central part. Such composites are commonly (albeit non-limitatively) used to cover vehicle (and motor vehicle if necessary) seats. [0003] As is known to those skilled in the art, various methods (or ways) have been proposed in order to realize a seat composite comprising a "pattern". [0004] A "pattern" is to be understood here to mean the definition of a shape, usually a geometric shape (for example rectangular or square), by seams. [0005] It has then been proposed to join a plurality of small pads, generally rectangular or square in shape, to one another, for...

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
