[0001] This disclosure relates to a seating system for use in vehicles. The vehicle seats are preferably rear seats, particularly second or third row seats, but are not limited to such uses. The seats can be a single seat, part of a bench seat, or a complete bench seat. In other words, the seats can specifically accommodate two or three people, but are not limited thereto. Background Technology
[0002] A seating system is known, comprising a vehicle floor and a seat panel extending longitudinally between a front region and a rear region, the front and rear regions extending laterally between a first side edge and a second side edge, the lateral direction being perpendicular to the longitudinal direction.
[0003] The purpose of this disclosure is to provide a robust seating system with reduced cost and lighter weight. Utility Model Content
[0004] According to this disclosure, the seating system also includes a front structure comprising a lower portion and an upper portion, the front structure extending between the lower and upper portions in a height direction perpendicular to the longitudinal and lateral directions, the lower portion being connected to the vehicle floor, and the upper portion supporting the seat plate in the front region, the rear region of the seat plate resting on the vehicle floor.
[0005] This eliminates the need for vehicle floor attachments, thus simplifying the seating system and reducing its weight and cost.
[0006] Advantageously, the seating system also includes padding and a cover layer, with the padding resting on the seat panel and the cover layer covering the padding.
[0007] In this way, the seat panel forms a suspension that supports the padding, while the overlay provides an aesthetically pleasing appearance and a comfortable contact with the user.
[0008] According to another feature of this disclosure, the seating system preferably further has the following features:
[0009] - Vehicle flooring includes a lower surface, a upper surface, and a rear surface.

[0011] - The upper surface extends perpendicular to the height direction, and the rear area of the seat panel rests on the upper surface.
[0012] - The rear surface extends substantially perpendicular to the longitudinal direction and connects the lower and upper surfaces.
[0013] In this way, the seat panel can be arranged substantially horizontally and raised sufficiently above the lower surface designed to accommodate the passenger's feet for comfortable seating.
[0014] According to another feature of this disclosure, the seat panel is preferably made of plastic material.
[0015] In this way, the quality of the seating system is easy to control, and the seat panel can be deformed to form a suspension that improves user comfort.
[0016] According to another feature of this disclosure, the front structure is preferably made of a metallic material.
[0017] In this way, the seating system can be robust while having a reduced front structure, i.e., a small footprint.
[0018] According to another feature of this disclosure, the front structure includes one of a transverse member, a tube supported by a leg, or a stud.
[0019] In this way, the front structure effectively supports the front area of the seat panel.
[0020] In various embodiments of the seating system according to this disclosure, any of the following arrangements may also be used:
[0021] - The front structure includes a transverse member that extends primarily in the transverse direction. The transverse member has a front wall, a top wall, and a rear wall.

[0025] - The front structure includes studs spaced laterally, each stud being rigidly attached to the vehicle floor via a lower portion and supporting the front area of the seat panel via an upper portion;
[0026] Each stud includes two arms forming a V shape, which are connected to each other at the upper part and spaced apart laterally at the lower part;
[0027] Each stud is shaped like a truncated pyramid.
[0028] According to this disclosure, the seating system further has at least one of the following features:
[0029] The rear area of the seat panel is not attached to the vehicle floor in the longitudinal direction;
[0030] The rear area of the seat panel is not attached to the vehicle floor in the lateral direction;
[0031] The rear area of the seat panel is not attached to the vehicle floor in the vertical direction;
[0032] The seat panel is attached to the vehicle floor only at the front.
[0033] Therefore, the creation of seating systems is simplified.
[0034] In various embodiments of the seating system according to this disclosure, any of the following arrangements may also be used:
[0035] - The seating system also includes a support on which the seat plate rests. The support includes a first longitudinal member and a second longitudinal member, which extend in the longitudinal direction between a front region and a rear region and are spaced apart in the transverse direction.

[0050] Figures 1 to 3 An example of a seating system is shown, which basically includes a seat panel 10, a vehicle floor 20, and a front structure 30.
[0051] The seat panel 10 extends in the longitudinal direction X between a front region 12 and a rear region 14. The seat panel 10 also includes a middle region 15, which is arranged in the longitudinal direction X between the front region 12 and the rear region 14. The front region 12, the middle region 15, and the rear region 14 extend in the transverse direction Y between a first side edge 16 and a second side edge 18. The transverse direction Y is perpendicular to the longitudinal direction X. The first side edge 16, the front region 12, the second side edge 18, and the rear region 14 form the periphery of the seat panel 10.
[0052] In the example shown, the seating system 10 is designed to form a rear seat that can accommodate at least two passengers, preferably three passengers. The seating system 10 is also suitable for manufacturing seats for different numbers of passengers, particularly for manufacturing individual seats. For this purpose, the dimensions of the seating system, particularly the dimensions of the seat panel 10 and the front structure 30 in the lateral direction Y, can be adjusted.
[0053] The seat panel 10 is preferably made of plastic. In addition, the seat panel 10 is preferably manufactured in one piece, that is, the seat panel 10 is made from a single piece (monomeric structure), and in particular, the seat panel 10 is obtained through a single molding operation.
[0054] The seat plate 10 preferably has a recess in the middle region 15 to increase the flexibility of the middle region 15 relative to the front region 12 and the rear region 14.
[0055] The front structure 30 includes a lower portion 32 and an upper portion 34. The front structure 30 extends along the height direction Z between the lower portion 32 and the upper portion 34. The height direction Z is perpendicular to the longitudinal direction X and the lateral direction Y. The front structure 30 is preferably made of metal. The lower portion 32 is connected to the vehicle floor 20, preferably, by means of welding, bolting, clamping, etc. The upper portion 34 supports the seat plate 10 in the front region 12.
[0056] The vehicle floor 20 generally includes a lower surface 22, an upper surface 26, and a rear surface 24. The lower surface 22 extends substantially perpendicular to the height direction Z and faces the central area 15 of the seat panel 10. The upper surface 26 extends perpendicular to the height direction Z. The rear surface 24 extends substantially perpendicular to the longitudinal direction X and is connected to the lower surface 22.
[0057] The lower part 32 of the front structure 30 can rest on (and be directly attached to) the lower surface 22 of the vehicle floor 20. However, in Figures 1 to 3 In the illustrated embodiment, the vehicle floor 20 also includes ribs 28 projecting from the lower surface 22, such that the lower portion 32 of the front structure 30 rests on (and is directly attached to) the ribs 28 of the vehicle floor 20.
[0058] The rear region 14 of the seat panel 10 has a support surface 13 that extends parallel to and opposite to the upper surface 26. Therefore, the rear region 14 of the seat panel 10 rests on the upper surface 26 of the vehicle floor 20.
[0059] The rear region 14 of the seat panel 10 is preferably not (directly) attached to the upper surface 26 of the vehicle floor 20. The rear region 14 of the seat panel 10 is not directly held to the vehicle floor 20 in either the longitudinal direction X or the transverse direction Y. Furthermore, in the height direction Z, the rear region 14 of the seat panel 10 is not directly held (fixed) to the vehicle floor 20; instead, it rests simply on the upper surface 26 of the vehicle floor 20, which limits the displacement of the rear region 14 of the seat panel 10 relative to the upper surface 26 of the vehicle floor 20 in only one direction (downward). As described below, the seat panel 10 is attached to the vehicle floor 20 only through the front region 12. Alternatively, the rear region 14 of the seat panel 10 may be held, for example, by means of a slotted sliding screw or a well-known clamping system in one or more of the longitudinal direction X, transverse direction Y, and height direction Z.
[0060] The upper part 34 of the front structure 30 can be directly connected to the seat plate 10. However, Figures 1 to 3 The seat system 10 shown also includes a support 70. The seat panel 10 is held on the support 70, and the support 70 is attached to the upper part 34 of the front structure 30 such that the front region 12 of the seat panel 10 is held on the front structure 30 via the support 70.
[0061] The support member 70 includes a tubular element 80, a first support lug 73, and a second support lug 77.
[0062] The tubular element 80 includes a first tubular portion 82, a second tubular portion 86, and a third tubular portion 84. The first tubular portion 82 and the second tubular portion 84 are straight and extend in the longitudinal direction X. The third tubular portion 84 is straight and connects the first tubular portion 82 and the second tubular portion 86. Therefore, the tubular element 80 is U-shaped perpendicular to the height direction Z.
[0063] The first tubular portion 82 extends along the first side edge 16. The second tubular portion 86 extends along the second side edge 18. The third tubular portion 84 extends into the front region 12. Therefore, the support member 70 extends close to the periphery of the seat plate 10. However, it should be noted that the support member 70 does not extend along the rear region 14 in the lateral direction Y.
[0064] The first tubular portion 82 has a free end to which a first support lug 73 is attached. Therefore, the first tubular portion 82 has an end attached to the first support lug 73 along the longitudinal direction X, and is continued at the opposite end by a third tubular portion 84. The second tubular portion 86 has a free end to which a second support lug 77 is attached. Therefore, the second tubular portion 86 has an end attached to the second support lug 77 along the longitudinal direction X, and is continued at the opposite end by a third tubular portion 84.
[0065] The first tubular portion 82 and the first support lug 73 form a first longitudinal member 72. The second tubular portion 86 and the second support lug 77 form a second longitudinal member 76. The first support lug 73 and the second support lug 77 are each placed on the upper surface 26 of the vehicle floor 20.
[0066] The first longitudinal member 72 and the second longitudinal member 76 extend in the longitudinal direction X between the front region 12 and the rear region 14. The first longitudinal member 72 and the second longitudinal member 76 are spaced apart in the transverse direction Y.
[0067] The third portion 84 of the tubular element 80 forms a connecting rod 74 that connects the first longitudinal member 72 to the second longitudinal member 76.
[0068] The seat plate 10 rests on the support member 70, and the upper part 34 of the front structure 30 supports the connecting rod 74, such that the upper part 34 of the front structure 30 supports the seat plate 10 in the front region 12 via the support member 70 and more specifically via the connecting rod 74.
[0069] The upper surface 26 of the vehicle floor 20 supports the seat plate 10 via the support member 70 and directly via the support surface of the rear region 14.
[0070] The seat panel 10 preferably includes rib-like reinforcements facing the vehicle floor 20 near a first side edge 16, a front region 12, and a second side edge 18. The rib-like reinforcements have grooves in which a tubular element 80 is received. The seat panel 10 also includes resiliently deformable retaining elements to retain the seat panel 10 relative to the support 70 and more precisely relative to the tubular element 80; however, other similar devices may also be suitable.
[0071] like Figure 3 As shown, the seat system 1 preferably also includes a padding material 2 and a covering layer 4. The padding material 2 rests on the seat panel 10. The covering layer 4 covers the padding material 2 and holds the padding material 2 in place relative to the seat panel 10.
[0072] exist Figures 1 to 3 In the illustrated embodiment, the front structure 30 includes studs 60. The studs 60 are spaced apart in the lateral direction Y. In the illustrated embodiment, the front structure 30 includes two studs 60. Different numbers of studs can be provided, preferably between two and four studs 60. Each stud 60 is attached to the vehicle floor 20 via a lower portion 32 and (via a connecting rod 74) supports the seat plate 10; more precisely, the front region 12 of the seat plate 10 is supported by the upper portion 34.
[0073] Each stud 60 includes a first arm 62 and a second arm 64 forming a V shape. The first arm 62 and the second arm 64 are connected to each other at the upper portion 34. The first arm 62 and the second arm 64 are spaced apart in the transverse direction Y at the lower portion 32.
[0074] The seating system 1 also includes a first side support 36 and a second side support 38. The first side support 36 and the second side support 38 extend in the height direction Z. The first side support 36 and the second side support 38 are attached to the vehicle floor 20. The first side support 36 supports a first longitudinal member 72, more precisely, a first portion 82 of a tubular element 80. The second side support 38 supports a second longitudinal member 76, more precisely, a second portion 86 of the tubular element 70.
[0075] Figure 4 The second implementation scheme shown is the same as Figures 1 to 3 The difference in the first embodiment shown is that the front structure 30 includes studs 90, each of which has a truncated pyramidal shape, preferably with a square base, in place of studs 60. The studs 90 extend from the upper portion 34 toward the lower portion 32, forming the base of the pyramid. Two studs 90 are shown for the front structure 30, but the front structure 30 may include any other number of studs 90, preferably between two and six. Additionally, the first side support 36 and the second side support 38 are preferably identical to the studs 90 on the front structure.
[0076] Figure 5 The third implementation scheme shown is the same as Figures 1 to 3 The difference in the first embodiment shown is that the front structure 30 includes a transverse member 40 in place of the stud 60.
[0077] A transverse member 40 extends in the transverse direction Y. The transverse member 40 has a front wall 42, an upper wall 44, and a rear wall 46. The front wall 42 has a lower front edge 41 and an upper front edge 43. The lower front edge 41 is rigidly attached to the vehicle floor 20. The rear wall 46 has an upper rear edge 45 and a lower rear edge 47. The lower rear edge 47 is rigidly attached to the vehicle floor 20. The upper wall 44 connects the upper front edge 43 to the upper rear edge 45.
[0078] exist Figure 5 In the third embodiment shown, the front wall 42 and the rear wall 46 each have a hole 48. Alternatively, these holes may exist in only one of the front wall 42 and the rear wall 46, or even in neither the front wall 42 nor the rear wall 46.
[0079] Regarding the first side support 36 and the second side support 38, the third embodiment is preferably no different from the first embodiment.
[0080] Figure 6 The fourth implementation scheme shown is the same as Figures 1 to 3 The difference in the first embodiment shown is that the front structure 30 includes a pipe 50 and feet 52 supporting the pipe 50. The pipe 50 extends primarily in the lateral direction Y. Each foot 52 includes a base portion 54 and a retaining portion 56. The base portion 54 is fixed to the vehicle floor 20, and the retaining portion 56 is connected to the pipe 50. Figure 6 In the fourth embodiment shown, the front structure 30 includes two legs 52. However, a different number of legs may be provided, preferably between two and four.
[0081] The tube 50 has a rotation axis 58 extending in the transverse direction Y and is annular in a cross section perpendicular to the transverse direction Y.
