Description

Title of the invention: Seat for motor vehicle TECHNICAL FIELD AND PREVIOUS ART

[0001] This application relates to a seat for a motor vehicle.

[0002] A motor vehicle seat usually comprises a frame, padding made up of various cushions or mattresses, for example foam or spring cushions, and upholstery covering the padding and frame, which upholstery notably includes a cover, for example a textile cover or a leather cover depending on the desired aesthetic appearance. FR3089167A1 provides an example of a motor vehicle seat. This example illustrates how complex known motor vehicle seats are, composed of numerous parts and costly to manufacture.

[0003] The present invention relates to a seat more particularly adapted and intended for small cars (such as golf carts) and for cars that do not require a driver's license and are authorized to travel on the road network excluding motorways. Cars that do not require a driver's license are four-wheeled mopeds that are subject to certain regulatory limitations. For example, in France, a car that does not require a driver's license may be equipped with a combustion engine (diesel) or an electric motor limited to 6 kW, and offer a limited number of seats to 2 people, an unladen mass limited to 425 kg, and a maximum speed limited to 45 km / h.

[0004] These vehicles offer a practical, low-cost transportation solution that is compatible with the greenhouse gas reduction objectives imposed by climate change.

[0005] The seat according to the invention can however also be installed in a "classic" car, which requires a driver's license.

[0006] The increasing integration of electronic systems in vehicles necessitates a reduction in the weight of other equipment. Furthermore, it is desirable to offer vehicles that are less expensive to be accessible to a wider range of people, lighter to have lower energy consumption, and more environmentally friendly, meaning not only less energy-intensive but also less material-intensive and generate less waste. Description of the invention

[0007] In this context, the invention aims to provide a lighter, less expensive, and easier-to-produce motor vehicle seat that is more environmentally friendly, but without sacrificing safety and offering satisfactory comfort (i.e., comfort comparable to the seats previously fitted to cars without a license, and sufficient for the (the seat according to the invention can also be fitted to a "classic" entry-level or even mid-range vehicle).

[0008] To this end, the invention proposes a motor vehicle seat having a seat and a backrest, the seat comprising:

[0009] - a peripheral frame, capable of supporting the presence of a person on the seat and configured to allow the seat to be anchored in a motor vehicle, and

[0010] - a textile cover.

[0011] The seat according to the invention is characterized in that:

[0012] - the textile cover directly covers the peripheral frame, the seat being devoid of a shell and cushion or mattress (except for a possible headrest cushion as described later),

[0013] - the textile cover is attached to the peripheral frame solely by means of elements additional non-point fixings, integrated respectively into the frame and the textile cover.

[0014] Thus, the seat according to the invention is devoid of cushions or mattresses (with the exception of a possible headrest cushion); in particular, it is devoid of foam or spring cushions in the seat area. It is also devoid of rigid shells. It may also be devoid of structural elements in central areas of the seat and backrest, the only essential structure being peripheral.

[0015] This minimalism is contrary to the habits of automotive seat designers and to the tendency towards over-equipment which exists in the automotive field and which pushes in particular to design ever more complex and expensive seats, for example by integrating various devices into the seats (heating or cooling element, motorized and electronic adjustment, to name only a few).

[0016] Due to this minimalism, the seat according to the invention is particularly light and inexpensive, but nevertheless sufficiently comfortable for use in a motor vehicle, as well as conforming to the safety standards in force provided that the materials used for the peripheral frame are chosen appropriately from known materials, without it being necessary to demonstrate inventive activity to do so.

[0017] Furthermore, the complementary non-point fixing elements according to the invention, integrated respectively into the cover and the frame, allow the cover to be easily and quickly mounted onto the frame with the desired tension. Since these elements are not point fixings, they prevent any initiation of breakage in the textile cover fibers and distribute the tensile stresses experienced by said cover. This also contributes to extending the cover's lifespan and resulting in a seat whose cover does not stretch or only slightly stretches over time, making the seat compatible with its use in a motor vehicle, in accordance with the R17 regulations in force in France.

[0018] In other words, no point fastener (whether independent or integrated into the cover or frame), nor any independent element (whether point or not), is provided for attaching the fabric cover to the peripheral frame. Thus, the method of mounting the cover to the frame requires no screws, snap fasteners, staples, or similar. The method of assembling the cover and the frame is therefore particularly simple and quick to perform, as will become clearer later.

[0019] It should be noted that, throughout this description, the expression "longitudinal direction of the seat" refers to the horizontal direction which, when the seat is installed in a vehicle, corresponds to the roll axis (front-to-back axis) of the vehicle. Furthermore, "transverse direction" refers to the horizontal direction that is orthogonal to this longitudinal direction and which corresponds to the pitch axis of the vehicle (parallel to the vehicle's axles) when the seat is installed in a vehicle.

[0020] Optionally and advantageously, the non-point fastening elements include:

[0021] - one or more rods, called attachment rods, provided in the peripheral frame And,

[0022] - for each of said attachment rods, a rod, hereinafter referred to as a rod fixing strips, sewn, welded or stapled along an edge of the textile cover, each of said fixing strips being provided with a groove bordered by an elastic lip, which groove is configured to receive by clipping said hook rod.

[0023] In possible embodiments of the invention:

[0024] - the peripheral frame comprises

[0025] - a first frame called the seat frame, which corresponds to the seat and which It comprises a front crossbar and two substantially parallel lateral bars, known as the lateral seat bars,

[0026] - a second frame, called the file frame, which corresponds to the seat file and which includes an upper crossbar and two other substantially parallel side bars, called backrest side bars;

[0027] - the textile cover comprises a first portion, called the seat portion, which covers the seat frame of the peripheral frame, and a second portion, called the backrest portion, which covers the backrest frame of the peripheral frame.

[0028] In possible embodiments of the invention:

[0029] - the back portion of the textile cover has a front face, a back face, a closed upper end and an open lower end, as well as a side opening fitted with a zipper and slider (commonly called Eclair®); preferably, the side opening extends to the open lower end of the backrest portion; in a possible variant, said back face may be replaced by one or, preferably, two (or more) straps at the back, in which case the backrest portion is devoid of a zipper and slider;

[0030] - the seating portion of the textile cover is generally rectangular and has a rear transverse edge, two lateral edges and a front transverse edge, the lower end of the front face of the backrest portion being sewn onto the seat portion of the cover near the rear transverse edge of said seat portion,

[0031] - the peripheral frame comprises three attachment rods, namely two rods lateral attachments extending in the longitudinal direction under the seat frame of the frame on each side of the seat, and a rear transverse attachment rod extending in the transverse direction under the seat frame at the rear of the seat;

[0032] - the lateral edges of the seating portion of the textile cover each incorporate a fixing rod configured to receive by clipping one of said lateral attachment rods, and the rear transverse edge of the seat portion of the textile cover incorporates a fixing rod configured to receive by clipping said rear transverse attachment rod.

[0033] Optionally and advantageously, the seat portion of the cover also includes a front flap along its front transverse edge, which front flap wraps around a front end (including the front transverse bar) of the seat frame of the peripheral frame.

[0034] Optionally and advantageously, the backrest frame of the structure includes, extending upwards from the previously defined side backrest bars, two converging side bars, called headrest side bars, which, together with the upper crossbar, define a headrest integrated into the backrest.

[0035] According to one possible feature of the invention, the seat and backrest frames of the peripheral structure are essentially made up of rigid, straight or bent tube sections, two successive tube sections among said rigid tube sections being rigidly fixed to each other by any suitable means such as welding, brazing, gluing, etc. These tube sections preferably have a circular cross-section; alternatively, they could have a polygonal cross-section (square, for example) with rounded corners. Some of these tube sections are shorter and are therefore referred to as "connectors" in the detailed description.

[0036] Each of the reinforcement bars defined above can be formed either by a single tube section or by several welded tube sections (or fixed by any other appropriate means) one after the other. Moreover, two successive bars, such as for example, on each side of the seat, the side seat bar and the side back bar, can be formed from a single section of bent tube, folded at the junction between said bars.

[0037] Advantageously, the various bars or tube sections of the peripheral frame are at least partially covered with anti-noise sleeves, made of felt or equivalent, designed to limit the noise that may result from the friction of the textile cover against the frame during the movements of a user present on the seat.

[0038] In possible embodiments of the invention, the peripheral frame comprises a lower part which, when the seat is installed in a vehicle, connects to a floor of the vehicle, this part comprising:

[0039] - on each side of the seat, a sliding and rail assembly, including a suitable rail to be fixed to a vehicle floor, and a slide configured to fit onto said rail and slide along it for the purpose of adjusting the seat position in the vehicle along its longitudinal direction,

[0040] - locking means for locking each of the slides in the rail to which It is associated with, and unlocking means to release said locking means and allow the slides to move relative to the rails,

[0041] - a front base, comprising a front lower crossbar and two uprights front lateral supports, each of said front lateral supports having an upper end fixed to the peripheral frame of the seat and a lower end fixed to the front lower crossbar, the front lower crossbar being fixed to the slides by its ends,

[0042] - a rear base comprising a rear lower cross member and two rear side uprights, each of said rear side uprights having an upper end fixed to the peripheral frame of the seat and a lower end fixed to the rear lower cross member, the rear lower cross member being fixed to the slides by its ends.

[0043] It should be noted that a seat without a sliding rail assembly also conforms to the invention; such a non-adjustable seat is used, for example, as a passenger seat. In this case, the frame may include legs as previously described, but the crossbars of these legs are directly fixed to the vehicle floor; alternatively, the legs have no crossbars and their uprights are directly fixed to the vehicle floor.

[0044] According to a possible feature of the invention, like the backrest and seat frames of the peripheral structure, the front and rear legs are essentially made of rigid tubes, straight or bent, preferably with a circular cross-section, two successive or adjacent tubes among said rigid tubes being rigidly fixed together by any appropriate means such as welding, brazing, gluing, etc.

[0045] Note that the textile cover may include an additional portion, called the lower portion, which wraps around and covers the lower part of the frame (which extends under the seat frame).

[0046] Optionally, the seat further comprises a headrest arranged in the upper part of the peripheral frame covered with the textile cover, which headrest includes a cushion. It also preferably comprises an elastic strap extending from one lateral edge of said cushion to the other, encircling the peripheral frame covered with the textile cover, in order to hold the headrest correctly in place.

[0047] Preferably, the headrest further comprises a flexible upper tab (for example made of fabric) by which it is attached to the textile cover, said tab being sewn on one side to an upper edge of said cushion and on the other side to the upper end of the textile cover.

[0048] Alternatively, the cushion is independent of the textile cover. In this case, the aforementioned tab is not present. Instead, the headrest may include an elastic strap as previously defined. Alternatively, the cushion may have, on its rear face, an upper flap into which at least one upper portion of the frame covered by the textile cover can be inserted.

[0049] According to one possible feature of the invention, the textile cover is made from materials selected from synthetic polyester (PE) fibers, synthetic polyester fibers coated with PVC, synthetic PVC fibers, a combination of the aforementioned materials or any other material allowing to obtain a textile whose tensile strength of the seams according to ISO 13935-2 is greater than or equal to 700N and / or the breaking strength according to ISO 1421 is greater than or equal to 200 daN and / or the tearing strength according to ISO 13937-2 is greater than or equal to 150N.This is only a non-limiting example; other types of textiles (including fabrics made from natural fibers, or fabrics with seam tensile strength and / or breaking strength and / or tear resistance outside the aforementioned ranges) may be used as long as the chosen textile is suitable for supporting the presence of a person on the seat.

[0050] According to a possible feature of the invention, the peripheral reinforcement is made of a material chosen from steels.

[0051] The invention extends to a motor vehicle equipped with at least one seat as previously described.

[0052] The invention extends to the manufacturing process for the seat described above. This process is particularly simple and quick to perform. It includes, in particular:

[0053] - the supply of the peripheral reinforcement;

[0054] - the supply of the textile cover;

[0055] - the installation of the textile cover on the frame, a step consisting of

[0056] - slip the backrest portion of the fabric cover onto the backrest frame of the structure peripheral, pull the seat portion of the cover forwards until the front crossbar of the peripheral frame is inserted inside the front reverse of the seat portion of the textile cover,

[0057] - pull the seat portion of the cover backwards until the rod of fixing the rear transverse edge of the seat portion of the cover to the rear transverse attachment rod of the frame,

[0058] - clip each of the fixing strips to the side edges of the seat portion of the cover on the corresponding lateral transverse hanging rod of the frame, close the zipper and slider of the back portion of the cover.

[0059] The actions described above for fitting the fabric cover to the frame are preferably carried out in the order indicated above. However, these actions could be carried out in reverse order, i.e., first by slipping the seat portion onto the seat frame and then slipping the backrest portion onto the backrest frame (particularly—but not exclusively—if the backrest portion has a reduced height on the back or if this back is replaced by straps). In this case, the fastening rods are preferably clipped after the backrest portion has been fitted (to facilitate its handling), and closing the zipper and slider remains the final action (provided that the backrest portion has such a closure, which is not the case if the back of the backrest portion is replaced by straps, for example).

[0060] If the cover includes a headrest, the latter can then be folded down onto the front of the backrest portion of the cover and its elastic strap is put in place.

[0061] Following this process, the cover is perfectly fitted and stretched over the peripheral frame. This result is achieved with a particularly simple and quick process, without screws or any independent fasteners, which contributes to producing a very inexpensive vehicle seat.

[0074] Identical or analogous elements represented in the aforementioned figures are identified by identical numerical references.

[0075] The figures together show an example of an embodiment of a seat according to the invention, which includes a peripheral frame 2 and a textile cover 6, only the peripheral frame 2 being illustrated in [Fig.1] to 5.

[0076] The seat comprises a seat, a backrest and a headrest integrated into the backrest.

[0077] The peripheral frame 2 consists of an assembly of steel tube sections, fitted together end-to-end and joined by any suitable method capable of giving the assembly resistance to impact and deformation compatible with the use of the seat as a motor vehicle seat. A method of fastening the tube sections together is preferably chosen that is easy and quick to implement, and does not require the use of additional parts (such as pins or bolts, for example) which would have the negative effect of complicating the seat manufacturing process or creating protruding parts in contact with the fabric cover. A welding fastening is therefore preferred.

[0078] The peripheral frame 2 comprises:

[0079] - a seat frame 8 corresponding to the seat of the seat,

[0080] - a file frame 10, which corresponds to the head office file and of which a part The upper 12 forms a headrest frame.

[0081] The seat frame 8 of the frame comprises a front crossbar 80, two side bars 82, and two elbow fittings 84, each connecting the front end of one of the side bars 82 with one end of the front crossbar 80. The assembly of the bars 80, 82, and the fittings 84 forms a rearward-opening seat frame 8. Note that the front crossbar 80 can be made up of several assembled tube sections (in the illustrated example, it comprises two) or of a single tube section.

[0082] For greater comfort, a front part of the side bars 82 of the seat frame is bent downwards; the front crossbar 80 is therefore located below the seating plane which contains the rear part of the side bars 82 and sufficiently far from this plane so that the user's thighs do not rest on the front crossbar 80 but rest only on the seating portion of the textile cover 6 which will be described later.

[0083] The frame 2 further includes an upper crossbar 102, two parallel backrest side bars 102 and two converging side bars 122, which form a backrest frame 10 open downwards.

[0084] In the illustrated example, on each side of the seat, the same bent tube 14 is used to form the seat side bar 82 of the seat frame and a lower portion of the backrest side bar 102 of the backrest frame. The bent tube 14 thus comprises a front portion 14a corresponding to the seat side bar 82 of the seat frame and a rear portion 14b corresponding to a lower portion of the backrest side bar 102 of the backrest frame.

[0085] The backrest side bar 102 of the backrest frame further includes a second tube 16 in the extension and alignment of the rear part 14b of the bent tube 14.

[0086] The upper crossbar 120 is here formed by a tube 20, and the two converging side bars 122 are formed by tubes 18 which converge towards the tube 20. The bars 120 and 122 delimit a head 12.

[0087] On each side of the seat, the tube 16 of the backrest frame and the tube 18 of the headrest are connected by an angled fitting 17 which forms an angle in the plane of the backrest defined by the tubes 16, i.e. viewed from the front (see [Fig.2]). This angle can be between 30° and 35° for example.

[0088] The elbow fittings 17 also form an angle in a vertical longitudinal plane of the seat, i.e. seen in profile or in section according to plane AA (see [Fig.3]), so that the tubes 18 -and therefore the headrest- extend globally in a vertical plane while the tubes 16 -and therefore the backrest- are inclined towards the rear.

[0089] On each side of the seat, the tube 20 and the tube 18 are also connected by an elbow fitting 19 which, in the example, forms an angle of 55° to 60° in the plane of the headrest defined by the tubes 18.

[0090] As can be seen in particular on [Fig.8] and 9, the different sections of tubes or tubes which make up the peripheral frame 2 are preferably at least partially covered with anti-noise sleeves 5.

[0091] The set of tube sections or tubes of the frame 2 form a closed frame which is directly covered by a textile cover 6 (see [Fig.8] to 11), the specifications of which in terms of tensile and tear resistance, and tension on the frame, in particular in the transverse direction, are adapted for the use of the seat as a motor vehicle seat.

[0092] Preferably, the textile cover is made of a polyester yarn fabric which has a seam tensile strength (ISO 13935-2) greater than or equal to 700N, a breaking strength (ISO 1421) greater than or equal to 200 daN and a tear strength (ISO 13937-2) greater than or equal to 150N. The cover is described in more detail later.

[0093] The frame further comprises, between the seat frame 8 and the ground or floor of a vehicle:

[0094] - a front base 40 comprising a front lower cross member 402 substantially horizontal, and two substantially vertical front lateral uprights 404, the upper end of which is fixed to one of the lateral base bars 82 of the frame and the lower end of which is fixed to the front lower cross member 402,

[0095] - a rear base 42 comprising a rear lower cross member 422 substantially horizontal, and two rear lateral uprights 424 substantially vertical, the upper end of which is fixed to one of the lateral seat bars 82 of the frame and the lower end of which is fixed to the rear lower cross member 422,

[0096] - on each side of the seat, a slide and rail assembly 44, comprising a slide 442 sliding mounted on a rail 444 intended to be fixed to a floor of the vehicle.

[0097] On each side of the seat, the end of the front lower cross member 402 is rigidly fixed to the slide 442 by means of a fixing bracket 408 or a spacer 409 screwed to said slide. Similarly, the end of the rear lower cross member 422 is rigidly fixed to the slide 442 by means of a fixing bracket 408 or a spacer 409 screwed to said slide.

[0098] Furthermore, the seat includes locking means for locking each of the slides 442 in the corresponding rail 444, and unlocking means including a pivoting control bar 46 whose actuation This allows the slides to be released, enabling adjustment of the seat position along its length. These methods are well known to those skilled in the art and will therefore not be detailed here.

[0099] Like the frame 2, the textile cover 6 includes a seat portion 62, a backrest portion 64, the upper part of which forms a headrest portion 66.

[0100] The backrest portion 64, including the headrest portion 66, comprises a front face 642 and a back face 644 sewn together along their entire height along one of their lateral edges. The backrest portion 64 (including the headrest portion 66) has a closed upper end 646, an open lower end 648 (see [Fig. 7]), and a lateral opening 650 that facilitates fitting the cover onto the frame and is closed by a zipper and slider 652.

[0101] The zipper and slider 652 is preferably sewn around the side opening using a zigzag stitch or double stitching to ensure the strength of the stitching in view of the tensile forces suffered in particular in the transverse direction by the portion of the back of the textile cover.

[0102] The seating portion 62 of the textile cover has a rear transverse edge 622, an anterior transverse edge 624 and two lateral edges 626.

[0103] The lower end of the front face 642 of the backrest portion of the cover is sewn onto the seat portion 62 near the rear transverse edge 622 thereof.

[0104] The front transverse edge 624 has a fold 628 which wraps around the front transverse bar 80 of the frame and allows the seat portion 62 of the cover to be positioned and stretched over the seat frame 8 of the frame.

[0105] The seat portion 62 has three fixing strips 7 which allow the textile cover 6 to be attached to the peripheral frame 2, each strip 7 clipping onto a hook rod 9 provided for this purpose on the frame.

[0106] To this end, each fixing strip 7 comprises a flat strip 72 sewn onto the textile cover along one of its edges, for example the lateral edge 626 of the seat portion visible in [Fig. 9]. In order to ensure a strong and lasting attachment of the fixing strip 7 to the textile cover 6 and to reduce the risk of tearing the cover at the seam of said strip, a hem is formed on the cover along the edge that receives the fixing strip 7; the strip is therefore sewn onto two layers of fabric of the cover (see [Fig. 9]).

[0107] The fixing strip 7 also has a groove 74 configured to receive one of the hook rods 9 of the peripheral frame 2. This groove 74 is bordered by a lip 76 which forms a spring-return clip retaining the hook rod 9 in the groove 74. This is why we speak of "clipping" the baguette on the hook rod, an effort must be applied to insert the hook rod into the groove or to remove it from it.

[0108] The use of the fixing strips 7 and the hook rods 9 as fixing elements of the textile cover on the peripheral frame 2, fixing elements which are not point-like and extend, in the example, almost over the entire width and depth of the seat, limits or even eliminates the risks of the cover initiating rupture at the point of its attachment to the frame.

[0109] In the illustrated example, the peripheral frame 2 comprises three attachment rods 9, namely:

[0110] - a rear transverse attachment rod 92 which extends transversely under the seat frame 8 at the rear of the seat, from one rear side post 424 to the other,

[0111] - and two lateral attachment rods 94 which extend longitudinally under the frame seat 8 on each side of the seat, from the front side post 404 to the rear side post 424.

[0112] Note that these lateral attachment rods 94 are not arranged vertically opposite the side bars 82 but are set back slightly towards the interior of the seat's overall dimensions. Similarly, the rear transverse attachment rod 92 is not located in the plane of the backrest defined by the backrest side bars 122, but is set back slightly from this plane towards the interior of the seat.

[0113] This ensures better tension of the cover, as well as better distribution of the forces transmitted between the cover and the side bars 82 of the seat frame which limits the risks of tearing of the cover.

[0114] The illustrated seat further includes a headrest 50 attached to the headrest portion 66 of the cover. This headrest comprises (see [Fig. 10] and 11):

[0115] - a cushion 52 formed by a rigid plate and a soft mattress glued to the face before the said plaque,

[0116] - a flexible tab 54 by which the cushion is attached to the textile cover 6, one end of said tab 54 being sewn to the upper end 646 of the headrest portion of the cover, the other end of the tab being sewn into the upper edge of the cushion 52,

[0117] - an elastic strap 56 which extends from one lateral edge of the cushion to the other and can be passed around the head frame of the peripheral frame covered with the textile cover as illustrated in [Fig. 11].

[0118] A seat according to the invention can be the subject of multiple variants provided that it has the characteristics of the attached claim 1.
