Description

Title of the invention: Vehicle seat

[0001] The present invention relates to a vehicle seat.

[0002] Classically, such a seat comprises a seat with padding permanently fixed to an internal structure.

[0003] The internal structure ensures that the padding is secured to the vehicle body and the padding is intended to support the body of a seat user.

[0004] In addition, the padding is intended to provide the user with a certain level of seating comfort. This comfort varies depending on the components of the seat.

[0005] However, when a padding support is provided in the seat, the seat user is likely to feel the padding support either by direct contact or through the padding.

[0006] There is therefore a need for a vehicle seat comprising a padding support and whose seating comfort is improved.

[0007] The aim of the invention is therefore to offer a vehicle seat with improved seating comfort.

[0008] To this end, the invention relates to a vehicle seat comprising a seat extending substantially along a horizontal plane defined by a longitudinal direction and a transverse direction, the seat comprising:

[0009] - a padding comprising a main seating surface intended to support the minus a part of the body of a seat user;

[0010] - a padding support comprising a first lateral part, a second lateral part opposite to the first lateral part in the transverse direction and an intermediate part situated between the first and second lateral parts in the transverse direction, the intermediate part extending inward in relation to the lateral parts in a direction of elevation substantially perpendicular to the longitudinal and transverse directions;

[0013] the central portion of each lateral part of the padding support having an upper surface inclined with respect to the horizontal plane in the direction of the intermediate part of the padding support.

[0014] The seat according to the invention offers improved user comfort. Indeed, the inclination of the upper surface of each central portion allows for improved The interaction of the user's body with the padding support, whether through direct contact with the sides of the padding support or through contact with the sides of the padding support via the padding itself. Furthermore, such inclined surfaces provide better support for the user's body in the transverse direction.

[0063] The invention will become clearer upon reading the following description, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0064] [Fig-1] - [Fig.1] is a schematic perspective representation of a seat of vehicle according to the invention;

[0065] [Fig.2] - [Fig.2] is a schematic perspective representation of an example seat base of the [Fig.1], in which the covering has been omitted;

[0067] [Fig.4] - [Fig.4] is a schematic cross-sectional representation of the base of [Fig.2] according to the IV-IV section plane;

[0068] [Fig.5] - [Fig.5] is a schematic cross-sectional representation of the seat of [Fig.2] similar to the representations in Figures 3 and 4, according to a first embodiment of the seat, in which the covering is shown and the internal structure is omitted;

[0069] [Fig.6] - [Fig.6] is a schematic cross-sectional representation of the seat of [Fig.2] similar to the representations in Figures 3 and 4, according to a second embodiment of the seat, in which the covering is shown and the internal structure is omitted;

[0070] [Fig.7] - [Fig.7] is a schematic cross-sectional representation of the seat of [Fig.2] similar to the representations in Figures 3 and 4, according to a third embodiment of the seat, in which the covering is shown and the internal structure is omitted;

[0071] [Fig.8] - the [Fig.8] is a schematic representation in view from below of a rear portion of the seat of the [Fig.2], illustrating an auxiliary part of the sure mattress support, an auxiliary support element and an auxiliary covering retaining element cooperating to hold the covering against the sure mattress.

[0072] In what follows, a longitudinal direction X is defined parallel to a median sagittal plane P of the seat, which is also a median sagittal plane of the seat base, a transverse direction Y substantially perpendicular to the longitudinal direction X and substantially parallel to the extension plane of a vehicle floor on which the vehicle is intended to be mounted, and an elevation direction Z substantially perpendicular to the longitudinal direction X and transverse direction Y.

[0073] A front and a rear are also defined so that the front corresponds to the direction in which a seat user faces along the longitudinal direction X when seated on the seat and the rear is opposite to the front.

[0074] With reference to figures 1 to 8, a vehicle seat 1 according to the invention is described.

[0075] The vehicle seat 1 comprises a backrest 3 and a seat 5, the backrest 3 being mounted on the seat 5.

[0076] As illustrated in [Fig.1], the vehicle seat 1 further includes an upright 7 on which the seat 5 is mounted. The upright 7 secures in particular the seat 5 and the backrest 3 with a floor 9 of the vehicle.

[0077] Case 3 is classic and will not be described in more detail here.

[0078] The base 5 extends substantially along a horizontal plane H defined by the longitudinal direction X and the transverse direction Y. In other words, the base 5 has dimensions along the longitudinal direction X and the transverse direction Y as well as along the elevation direction Z, the dimensions of the base 5 along the longitudinal directions X and transverse Y being greater than the dimensions of the seat 5 along the elevation direction Z.

[0079] With reference to figures 2 to 8, the seat 5 includes a padding 16 having a main seating surface 48 intended to support at least part of the body of a seat user 1 and a padding support 14.

[0080] Advantageously, the seat 5 further comprises an internal structure 12.

[0081] Even more advantageously, the seat 5 includes a covering 18 covering at least partially the padding 16.

[0082] Further advantageously, with reference to figures 5 to 7, the seat 5 further comprises at least one first element 70 for holding the cover 18 against the padding 16 and at least one second element 72 for holding the cover 18 against the padding 16. For example, at least one first holding element 70 is mounted on a first support element 42 of the padding support 14, described below, and at least one second holding element 72 is mounted on a second support element 44 of the padding support 14, also described below.

[0083] In particular, as illustrated in the example of Figures 5 to 7, at least one first retaining element 70 and at least one second retaining element 72 each comprise a clip.

[0084] Advantageously, the seat 5 comprises a plurality of retaining elements 70 and a plurality of retaining elements 72.

[0085] Even more advantageously, with reference to [Fig.8], the seat 5 further comprises at least one first auxiliary element 90 for holding the cover 18 against the padding 16 and at least one second auxiliary element (not illustrated) for holding the cover 18 against the padding 16.

[0086] For example, at least one first auxiliary retaining element 90 is mounted on a first auxiliary support element 94 of the padding support 14, described below, and at least one second retaining element is mounted on a second support element (not illustrated) of the padding support 14, also described below.

[0087] In particular, as illustrated in the example of [Fig.8], the at least first auxiliary retaining element 90 and the at least second auxiliary retaining element each comprise a retaining piece 91, in particular a piece of flat rectangular shape.

[0088] The internal structure 12 is for example mounted, in particular permanently, on the upright 7 of the seat 1 and constitutes a support for the padding 16 and the padding support 14. For example, the internal structure 12 is fixed to the upright 7 of the seat 1 by screwing and / or welding.

[0089] The internal structure 12 is, for example, made of a metallic material, in particular steel.

[0090] The internal structure 12 contributes to the resistance of the seat 5 to deformations and shocks.

[0091] As illustrated in figures 2 to 4, the internal structure 12 comprises a first lateral part 20 and a second lateral part 22 opposite to the first lateral part 20 along the transverse direction Y.

[0092] The first lateral part 20 and the second lateral part 22 extend, for example, substantially along the elevation direction Z.

[0093] According to the example illustrated in Figures 2 to 4, each lateral part 20, 22 has a U-shaped form. Each lateral part 20, 22 includes in particular a base 24 extending substantially in a plane defined by the elevation Z and longitudinal X directions and two branches 25 extending from opposite ends of the base 24 along the elevation Z direction. Each branch 25 extends substantially in a plane defined by the longitudinal X and transverse Y directions.

[0094] For example, a branch 24 of each side portion 20, 22 extends opposite the upright 7 so as to be fixed thereto. As will be explained in more detail below, the opposite branch 24 extends opposite a side portion 30, 32 of the mattress support 14.

[0095] According to the example illustrated in figures 2 to 4, the lateral parts 20, 22 of the internal structure 12 are substantially symmetrical with respect to the median sagittal plane P of the seat 5.

[0096] The first and second lateral parts 20, 22 delimit a volume in which, as will be described in more detail below, the padding support 14 and the padding 16 extend at least partially.

[0097] As illustrated in the example of Figures 2 to 4, the padding support 14 is mounted on the internal structure 12. For example, the padding support 14 is fixed to the internal structure 12, in particular to a rear tube of the internal structure 12, in particular by means of a pin, or more particularly by means of at least one forward-opening hook, preferably two forward-opening hooks. For example, the padding support 14 is further clipped onto the internal structure 12, in particular onto the rear tube of the internal structure 12, by means of at least one clip, preferably two clips.

[0098] Advantageously, the padding support 14 extends along the longitudinal direction X between a rear edge 14A connected to the backrest 3 and a front edge 14B opposite the rear edge 14A.

[0099] The padding support 14 is in particular mounted in a removable manner on the internal structure 12 and is suitable for being replaced by an auxiliary padding support (not illustrated) which will be described in more detail below.

[0100] The padding support 14 is, for example, made of a plastic material, in particular a mixture of polyethylene and polypropylene (PE / PP mixture), preferably a PE / PP mixture comprising mineral fillers.

[0101] Advantageously, the padding support 14 is made in one piece.

[0102] Even more advantageously, the padding support 14 is made of a more rigid than that of the 16-inch padding.

[0103] The padding support 14 comprises a first lateral part 30, a second lateral part 32 opposite the first lateral part 30 in the transverse direction Y and an intermediate part 34 located between the first and second lateral parts 30, 32 in the transverse direction Y.

[0104] Advantageously, the padding support 14 further comprises at least one first auxiliary part 35A and at least one second auxiliary part (not shown) each extending from the first lateral part 30 and / or the second lateral part 32 and / or the intermediate part 34 of the padding support 16 in the longitudinal direction X towards the rear of the seat 5.

[0105] Further advantageously, at least a second auxiliary part of the padding support 14 is arranged symmetrically with respect to at least a first auxiliary part 35A of the padding support 14 with respect to the median sagittal plane of the seat 5.

[0106] Advantageously, the first side part 30 and the second side part 32 are intended to hold at least one part of the user's body in the seat 1 in the transverse direction Y. In particular, when the user sits on the seat 5, his pelvis sinks slightly into the padding 16 so as to be held transversely by the side parts 30 and 32.

[0107] Further advantageously, the first lateral part 30 of the padding support 14 is mounted on the first lateral part 20 of the internal structure 12 and the second lateral part 32 of the padding support 14 is mounted on the second lateral part 22 of the internal structure 12.

[0108] With reference to Figures 2 to 7, the first lateral part 30 includes in particular a central portion 36 and a portion 37 for joining to the intermediate part 34 of the padding support 14

[0109] Advantageously, the first lateral part 30 further comprises a covering portion 38 extending substantially parallel to the joining portion 37.

[0110] In particular, the junction portions 37 and the overlap portions 38 extend respectively from opposite edges of the central portion 36 in the direction transverse Y. For example, the junction portions 37 and overlap portions 38 extend substantially in a plane defined by the longitudinal direction X and the elevation direction Z.

[0111] The junction portion 37 extends opposite the median sagittal plane P of the base 5.

[0112] Advantageously, the central portion 36, the junction portion 37 and the portion of overlap 38 delimit a space 39 for the insertion of a lateral part 20, 22 of the internal structure 12.

[0113] According to the examples illustrated in figures 2 to 7, the second lateral part 32 is substantially symmetrical to the first lateral part 30 with respect to the median sagittal plane P of the seat 5.

[0114] In other words, the second lateral part 32 also includes a central portion 36, a junction portion 37 and where applicable a cover portion 38 as described above.

[0115] According to a particular example, each junction portion 37 participates in maintaining at least one part of the user's body in the seat 1 in the transverse direction Y when the user is seated on the seat 5.

[0116] As illustrated in the examples in Figures 2 to 4, each lateral part 30, 32 of the padding support 14 covers at least partially the lateral part 20, 22 of the internal structure 12 on which it is mounted.

[0117] In particular, the cover portion 38 at least partially covers the corresponding base 24. In one particular example, the cover portion 38 covers the entire base 24, so that the corresponding lateral part 20, 22 is at least partially hidden from the outside of the seat 5. This makes it possible, in particular, to improve the aesthetics of the seat 5 by, for example, hiding elements of the internal structure 12.

[0118] The central portion 36 of each lateral part 30, 32 of the padding support 14 has an upper surface 60 inclined with respect to the horizontal plane H in the direction of the intermediate part 34 of the padding support 14. In other words, a vector substantially normal to the upper surface 60 is oriented substantially in the direction of the median sagittal plane P of the seat 1. Advantageously, the upper surface 60 is intended to be oriented in the direction of at least one part of the body of the seat user 1 when at least one part of the body of the seat user 1 rests on the padding 16.

[0119] Advantageously, the upper surfaces 60 of the central portions 36 are intended to maintain in position at least one part of the body of the seat user 1 in the transverse direction Y.

[0120] In what follows, a single upper surface 60 is described. Of course, the description applies to the upper surfaces 60 of each lateral part 30, 32.

[0121] The upper surface 60 comprises an inner edge 62 and an outer edge 64 extending substantially along the longitudinal direction X.

[0122] The inner edge 62 is connected to the corresponding junction portion 37.

[0123] The outer edge 64 is opposite the inner edge 62. For example, the outer edge 64 is connected to the corresponding overlap portion 38, so that the upper surface 60 connects the corresponding junction portions 37 and overlap portions 38.

[0124] With reference to Figures 3 and 4, the upper surface 60 is such that for each abscissa taken along the longitudinal direction X, the corresponding point on the inner edge 62 and the corresponding point on the outer edge 64 extend substantially along a straight line DX forming an angle α with the horizontal plane H. Figures 3 and 4 illustrate two sections of the base 5 at different abscissas taken along the longitudinal direction X and along section planes III-III, IV-IV parallel to the vertical plane defined by the transverse direction Y and the elevation direction Z. Figures 3 and 4 each illustrate the straight line DX connecting the corresponding point on the inner edge 62 and the corresponding point on the outer edge 64.

[0125] As illustrated in the example of Figures 2 to 4, the angle α between the line DX and the horizontal plane H varies continuously along the longitudinal direction X. In particular, the angle α between the line DX and the horizontal plane H is greater the closer the abscissa taken along the longitudinal direction X is to the rear edge 14A of the padding support 14. Thanks to this feature, the support of the user's pelvis in the transverse direction Y, which, under normal conditions of use of the seat 1, is close to the rear edge 14A of the padding support 14, is improved. Indeed, under normal conditions of use of the seat 1, the user's weight is more evenly distributed over the rear of the seat 5, so that the user's body sinks more deeply into the padding 16 at the rear of the seat 5.The large angle between the line DX and the horizontal plane H then allows significant cooperation between the upper surfaces 60 and the user's pelvis so as to maintain the pelvis in position along the transverse direction Y.

[0126] Advantageously, as illustrated in the examples in Figures 3 and 4, the upper surface 60 is concave. By "concave," it is understood that the upper surface 60 is curved towards space 39. In other words, the upper surface 60 extends in the opposite direction to the median sagittal plane P of the seat 1 relative to the lines DX. Thanks to this feature, the comfort of the seat 1 user is improved because the upper surface 60 substantially conforms to the convex shape of at least one part of the seat 1 user's body, in particular, for example, the user's pelvis and / or legs.

[0127] The intermediate part 34 of the padding support 14 extends inward relative to the lateral parts 30, 32 of the padding support 14 in the direction of elevation Z. In particular, the intermediate part 34 extends into the volume delimited by the first and second lateral parts 20, 22 of the internal structure 12.

[0128] As illustrated in figures 2 to 7, the intermediate part 34 extends between the ends of the joining portions 37 of the lateral parts 30, 32 of the padding support 14, opposite the respective central portions 36.

[0129] The intermediate part 34, the first lateral part 30 and the second lateral part 32 delimit a space 40 for receiving the padding 16.

[0130] In particular, when the user sits on the seat 5, his pelvis sinks slightly into the space 40 receiving the padding 16 so as to be held transversely by the lateral parts 30 and 32, in particular by the upper surfaces 60.

[0131] Advantageously, the padding support 14 further comprises at least one first element 42 for supporting a retaining element and at least one second element 44 for supporting a retaining element.

[0132] In particular, the padding support 14 comprises a plurality of first support elements 42, in particular as many first support elements 42 as the seat 5 comprises first retaining elements 70, and the padding support 14 comprises a plurality of second support elements 44, in particular as many second support elements 44 as the seat 5 comprises second retaining elements 72. In particular, each support element 42, 44 cooperates with a retaining element 70, 72.

[0133] At least one first support element 42 is arranged on the central portion 36 of the first lateral part 20 opposite the padding 16 and at least one second support element 44 is arranged on the central portion 36 of the second lateral part 22 opposite the padding 16.

[0134] For example, when the padding support 14 comprises a plurality of first support elements 42, the first support elements 42 are distributed over the central portion 36 of the first lateral part 20 along the longitudinal direction X. For example, when the padding support 14 comprises a plurality of second support elements 44, the second support elements 44 are distributed over the central portion 36 of the second lateral part 22 along the longitudinal direction X.

[0135] Advantageously, at least a second support element 44 is arranged symmetrically with respect to at least a first support element 42 with respect to the median sagittal plane of the seat 5.

[0136] Advantageously, as illustrated in the examples in Figures 5 and 6, at least one first support element 42 and at least one second support element 44 each comprise a through hole 46 formed in the central portion 36 corresponding to the padding support 14, in which a clip of the first retaining element 70 or of the second retaining element 72 is mounted through.

[0137] Advantageously, with reference to the example in [Fig.8], the padding support 14 further comprises at least a first auxiliary element 94 for supporting auxiliary retaining element 90 and at least a second auxiliary element (not shown) for supporting auxiliary retaining element.

[0138] At least one first auxiliary support element 94 is arranged on the first auxiliary part 35A of the padding support 14 and at least one second auxiliary support element is arranged on the second auxiliary part of the padding support 14.

[0139] Advantageously, at least one second auxiliary support element is arranged symmetrically with respect to at least one first auxiliary support element 94 with respect to the median sagittal plane of the seat 5.

[0140] Advantageously, as illustrated in the example of [Fig.8], at least one first auxiliary support element 94 and at least one second auxiliary support element each comprise an opening 95 provided in at least one corresponding auxiliary part 35A of the padding support 14, into which the retaining piece 91 of the first auxiliary support element 90 or of the second auxiliary support element is inserted through, said retaining piece 91 cooperating with the edges 96 of the opening 95 to hold the cover 18 against the padding 16.

[0141] As illustrated in figures 2 to 7, the padding 16 is mounted on the padding support 14 and extends at least partly into the receiving space 40.

[0142] Advantageously, according to the example illustrated in figures 2 to 7, the padding 16 extends at least in part over each of the lateral parts 30, 32 of the padding support 14.

[0143] According to the examples illustrated in Figures 2 to 7, the padding 16 extends over at least a portion of each of the upper surfaces 60 of the corresponding central portions 36.
