[0007] 3022504 B13301 - 3611 1.EN 4 Detailed description For the sake of clarity, only the steps and elements useful for understanding the embodiments that will be described have been shown and will be detailed. In particular, the realization of the other elements of the seat and in particular of the frame and the padding has not been detailed, the described embodiments being compatible with the usual embodiments of such elements. It should be noted that, in the figures, the structural and / or functional elements common to the different embodiments may have the same references and may have identical structural, dimensional and material properties. In the following description, when reference is made to absolute position qualifiers, such as the terms "forward", "backward", "up", "down", "left", "right", etc. , or relative, such as the terms "above", "below", "upper", "lower", etc., or with qualifiers for orientation, unless otherwise stated refers to the orientation of the figures or to a seat in its normal position of use. Figure 1 shows schematically and partially, a seat 1 for a motor vehicle. Such a seat is generally made of a seat 12, on which is articulated a backrest 14, where appropriate surmounted by a headrest 16. A frame of the seat is fixed to the floor of the vehicle (not shown), for example by a slide mechanism or by a hinge for a folding seat. Figure 1 essentially illustrates the visible appearance of the seat, that is to say the external appearance of its cap. Usually, the cap is made of several pieces sewn together. The pieces can be leather, skin, woven or non-woven fabric, synthetic material, etc.
[0008] 3022504 B13301 - 3611 1.EN 5 The seam lines between the pieces form the outer design of the cap and give it its style. The pieces can be of different colors, or even different materials relative to each other.
[0009] In the embodiment shown, the backrest 14 and the headrest 16 each comprise a rod 2 projecting from the surface of the cap at a seam. For example, for the backrest, this ring 2 is provided in the seam between the upper portion 142 of the cap and the central portion 144 10 defining a backrest medallion. For the headrest 16, a rod 2 is provided between the front portion 162 of the cap and the upper portion 164. These are examples and a rod can be provided at any seam, including included in the side or rear faces of the seat elements.
[0010] Unlike the usual beads which extend all along a seam, the ring provided by the described embodiments preferably does not extend to the edges of the cushion for which it is intended. Figure 2 is a top view of an embodiment of a rod 2 between two parts 32 and 34 of the cap. As is apparent from this figure, the seam 3 assembly between the two parts 32 and 34 is sometimes above the ring 2, sometimes below. In other words, at least one (first) section 22 of the ring is above the cap and at least one (second) section (not visible in FIG. 2) is masked by the cap. Preferably, only a central portion 22 of the rod exits the cap, the two end portions being inside the cap. Figure 3 is a side view of the ring 2 of Figure 2. As indicated above, the ring 2 has a section 22 outside the cap, that is to say above the plane or the overall apparent surface of the cap and, in this example, two sections 24 on either side of the section 22.
[0011] 3022504 B13301 - 3611 1.EN 6 In the embodiment illustrated in Figure 3, the ring 2 comprises a portion 41 of circular section and a portion 43 of cross section. The portion of straight or vertical section remains, at least in part, under the cap, that is, under the seam 3. FIGS. 4A, 4B and 4C are cross-sectional views of an embodiment of FIG. a ring 2a, respectively along the lines A, B and C of Figure 3. The ring 2a comprises a core 5, for example made 10 in the form of a plastic profile. The core 5 comprises, for example, a portion 51 of circular section (for example but not necessarily hollow in the center) and a portion or foot 53 of straight section. A thickness of foam 25 surrounds the plastic core and a coating material 27 covers this thickness of foam, or directly the core 51 in the absence of foam thickness. The coating material may be a simple transparent plastic film (eg marked with a logo, a pattern, etc.), a piece of leather, skin, textile, synthetic material, etc. according to the desired aesthetic effect.
[0012] The ring 2a is preassembled, that is to say that a third part comprising the coating 27, and if appropriate the foam 25 are assembled having, for example, their stitched edges (seam 29) at the foot 53 of The core-forming part 5 thus has an elongate shape and is independent of the parts 32 and 34 of the cap. In Figures 4A to 4C, to bring out the various elements 5, 25 and 27 constituting the rod 2a, these elements have been shown with different dimensions from each other. This is not necessary, however.
[0013] FIG. 4A illustrates the appearance of the cap at the segment 22. The rod 2a protrudes with respect to the surface of the cap whose parts 32 and 34 arrive at the level of the foot 53. The portion 41 of circular section of the rush is out of the headdress. The seam 3 takes respective edges 322 and 324 of the pieces 32 and 34 and passes through the foot 53. The pieces 32 and 34 are sewn under the portion 41 of circular section of the ring 2a. Figure 4B illustrates the appearance of the cap at a section 24. Here we find the appearance of a direct seam 5 edges 322 and 324 of two parts 32 and 34 of the cap between them. FIG. 4C illustrates the appearance of the cap at the interface between the sections 22 and 24, that is to say when the portion 41 of circular section passes from above to below the cap. A particularity is that the seam 3 is not interrupted between the sections 22 and 24. In other words, at the interface between the sections 22 and 24, the seam 3 passes through the circular portion 51 of the core 5 of the ring. The plastic material constituting the core of the ring 2a 15 is therefore chosen to be sewn. It is not too rigid so as not to break under the effect of the needle during sewing. Figures 5, 6 and 7 are sectional views of rods 2b, 2c and 2d illustrating alternative embodiments.
[0014] In FIG. 5, the ring 2b comprises a plastic core 5b, of circular section, without a foot or a straight part. In the example of FIG. 5, the third part comprises, as in FIGS. 4A to 4C, a thickness of foam 25 and a covering 27. The two edges of the third part are directly assembled to one another, for example by being sewn, glued or melted. In Figure 6, the ring 2c comprises a plastic core 5 coated with a transparent film 27c and devoid of foam thickness.
[0015] In Figure 7, the rod 2d is a single piece of material, for example plastic, capable of being sewn. For example, the ring 2d is, in section, formed of a part folded on itself to define the circular portion 41 and the straight portion 43. In Figure 7, the parts 32 and 34 are shown as in Figure 4A .
[0016] 3022504 B13301 - 3611 1.EN 8 The dimensions of the ring 2 depend on the desired effect. These dimensions are however chosen to be compatible with the realization of a seam, not only at the level of the foot but also at the portion of circular section 5. As a particular embodiment, the plastic core 5 or the ring 2d has, in section, a height of between less than 1 cm (for example, about 0.8 cm) and a few centimeters (for example about 3 cm). cm). The portion 51 or 41 of circular section has, for example, a diameter of between 4 mm and 1 cm. The portion 53 or 43 of rectilinear section has, for example, a height of between 4 mm and 2 cm. An advantage of the embodiments which have been described is that it is now possible to confer on a seat cover an aesthetic appearance with rushes which do not extend while another compatible with the 20 does not require any reporting. (slip on) Note along a seam line. advantage is that the cap is made customary padding. In particular, it changes the padding on which the cap. that the flexibility of the ring allowing it to pass under the cap also allows it to follow a curved line of seam line.
[0017] What has been described in connection with an example applied to a backrest or a seat headrest applies, of course, to any seat element for a motor vehicle, and therefore to a seat. In addition, the constituent materials of the caps may differ according to assembled parts to form the areas of the seat. Various embodiments have been described. Various variations and modifications will be apparent to those skilled in the art. In particular, the dimensions of the ring may vary according to the embodiments. For example, it is possible to provide a ring 35 alternating the passages on and under the cap and then comprising several first sections and more than two second sections. According to another variant, intended for the case where the rod stops at the edge of the cap, one of its end does not pass under the cap, the rod then has only a second section at one end of a first section. In addition, although a seam assembly is a preferred embodiment, it can be provided to assemble the parts by gluing the edges of the parts together, or by melting (in the case of synthetic materials). In addition, the cap pieces may be coated on the back side with a foam layer. Finally, the practical implementation of the described embodiments is within the abilities of those skilled in the art from the functional indications given above, whether for sewing techniques or techniques for making the ring.
