Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the vehicle seat described in Patent Document 1 above does not consider suppressing the visibility of sheet constituent members such as fastening members from between the seat back and the seat cushion. For example, in the vehicle seat described in Patent Document 1 above, it is conceivable that sheet constituent members such as fastening members arranged inside the side shield are visible from between the seat back and the seat cushion.

[0005] In consideration of the above facts, an object of the present invention is to obtain a vehicle seat capable of suppressing the visibility of sheet constituent members from between the seat back and the seat cushion.

Means for Solving the Problems

[0006] A vehicle seat according to the first embodiment comprises a seat cushion having a cushion pad and a cushion trim covering the cushion pad, supporting the buttocks of a seated occupant from below; a seat back having a back pad and a back trim covering the back pad, supporting the back of a seated occupant from the rear of the seat; a seat component provided between the seat cushion and the seat back; and a fin portion provided on one of the cushion trim and the back trim, extending upwards toward the other side of the cushion trim and the back trim and covering the seat component.

[0007] According to the first embodiment of the vehicle seat, a fin portion is provided on one of the cushion trim and the back trim. This fin portion extends upwards on the other side of the cushion trim and back trim, covering the seat component. This prevents the seat component from being visible from between the seat back and the seat cushion.

[0008] In the second embodiment of the vehicle seat, the fin portion has a structure in which multiple sheet-like members are stacked on top of each other, as is the case with the vehicle seat of the first embodiment.

[0009] According to the second embodiment of the vehicle seat, the fin portion has a structure in which multiple sheet-like members are stacked on top of each other. This makes it easier to maintain the fin portion in an upright position compared to when the fin portion has a single-layer structure. [Effects of the Invention]

[0010] The vehicle seat according to the present invention has the excellent effect of suppressing the visibility of the seat components from between the seat back and the seat cushion. [Brief explanation of the drawing]

[Figure 6] This diagram illustrates the process of forming the fin portion, showing the sheet-like material shown in Figure 5 folded and sewn. [Figure 7] This diagram illustrates the process of forming the fin portion, showing the sheet-like material in the reversed state after completing the process shown in Figure 6. [Modes for carrying out the invention]

[0012] A vehicle seat 10 according to an embodiment of the present invention will be described with reference to Figures 1 to 7. The arrows FR, UP, RH, and LH in the figures indicate the front, top, right, and left sides of the seat, respectively, as viewed from the perspective of an occupant seated in the vehicle seat 10. Hereafter, when simply referring to the front-to-back, up-and-down, and left-to-right directions, unless otherwise specified, these refer to the front-to-back direction of the seat, the up-and-down direction of the seat, and the left-to-right direction of the seat. The left-to-right direction of the seat coincides with the seat width direction.

[0013] As shown in Figures 1, 2, and 3, the vehicle seat 10 of this embodiment includes a seat cushion 12 that supports the seated occupant's buttocks from below, and a seat back 14 that supports the seated occupant's back from the rear.

[0014] The seat cushion 12 comprises a pair of left and right side frame sections 16 (see Figure 3) spaced apart in the seat width direction, and a cushion pan (not shown) stretched across the pair of left and right side frame sections 16. The seat cushion 12 also comprises a cushion pad 18 supported from below by the cushion pan, and a cushion trim 20 covering the cushion pad 18, etc.

[0015] The cushion pad 18 is formed in a block shape using, for example, urethane foam. The lower part of the cushion pad 18 is fitted into the cushion pan and supported by the cushion pan. In addition, the surface of the cushion pad 18 facing the seated occupant is covered by a part of the cushion trim 20.

[0016] As shown in Figures 1, 2, and 4, the cushion trim 20 comprises a first covering portion 20A that covers the seated occupant side of the cushion pad 18, and a second covering portion 20B that is connected to the first covering portion 20A and covers the rear of the cushion pad 18 and the lower surface of the cushion pan. The first covering portion 20A is formed using, for example, a cloth or synthetic leather that has a pleasant feel. The second covering portion 20B is formed using a cloth-like material that is harder than the first covering portion 20A. As shown in Figures 1 and 4, a fin portion 38, which will be described later, is fixed to the second covering portion 20B.

[0017] As shown in Figures 1, 2, and 3, the seat back 14 comprises a back frame (not shown) that constitutes the frame of the seat back 14, a back pad 22 supported by the back frame, and a back trim 24 that covers the back pad 22.

[0018] As shown in FIG. 3, between the seat cushion 12 and the seat back 14, a pair of left and right reclining devices 26 are provided to support the seat back 14 so as to be reclinable (tiltable) in the front-rear direction with respect to the seat cushion 12. Here, FIG. 3 shows the left reclining device 26 that connects the left rear end portion 12A of the seat cushion 12 and the left lower end portion 14A of the seat back 14. Note that the configurations of the left reclining device 26 and the right reclining device 26 are symmetrically configured. Therefore, hereinafter, the left reclining device 26 will be described, and the description of the right reclining device 26 will be omitted.

[0019] The reclining device 26 includes a base plate 28 fixed to the rear end portion of the side frame portion 16 and a rotation support portion (not shown) fixed to the base plate 28. By engaging this rotation support portion with the back frame of the seat back 14, the seat back 14 can be reclined in the front-rear direction with respect to the seat cushion 12.

[0020] By the way, a bolt 30 as a seat component member is inserted through the base plate 28. Further, a weld nut 32 as a seat component member is fixed to the rear end portion of the side frame portion 16. Then, by screwing the bolt 30 inserted through the base plate 28 into the weld nut 32 fixed to the rear end portion of the side frame portion 16, the base plate 28 is fixed to the rear end portion of the side frame portion 16.

[0021] As shown in FIGS. 1 and 2, the above-described left reclining device 26 is covered by a side fin 34 attached to the seat cushion 12 side. Further, a buckle 36 protrudes from the side fin 34 that covers the left reclining device 26.

[0022] Figure 2 shows a diagram corresponding to Figure 1, in which the fin portion 38, described later, is omitted. As shown in this diagram, when the fin portion 38, described later, is not provided, a part of the bolt 30 and the weld nut 32 are visible from between the left rear end 12A of the seat cushion 12 and the left lower end 14A of the seat back 14. Therefore, as shown in Figure 1, in the vehicle seat 10 of this embodiment, by providing the fin portion 38, described later, a part of the bolt 30 and the weld nut 32 are prevented from being visible from between the left rear end 12A of the seat cushion 12 and the left lower end 14A of the seat back 14.

[0023] As shown in Figures 5 to 7, the fin portion 38 is formed by sewing or other processing onto a sheet-like member 40 that has been cut into a predetermined shape. In this embodiment, the fin portion 38 is formed using the same material as the second covering portion 20B as an example.

[0024] Figure 5 shows a view of a sheet-like member 40, cut to a specified shape and dimensions, from the thickness direction. Figure 5 also shows the center line L. In this embodiment, the sheet-like member 40 has a symmetrical shape across the center line L. Specifically, the sheet-like member 40 has a hexagonal shape.

[0025] Then, as shown in Figure 6, the sheet-like member 40 is folded in half at the point corresponding to the center line L. Next, two points on the folded sheet-like member 40 are sewn together. In this embodiment, with the ends on one side and the other side of the folded sheet-like member 40 in the direction in which the center line L extends being designated as seam allowances 40A, the parts 40B on one side and the other side 40C of the folded sheet-like member 40 in the direction in which the center line L extends are sewn together in a straight line along a direction perpendicular to the center line L.

[0026] Next, as shown in Figure 7, the sheet-like member 40 that has completed the process shown in Figure 6 is turned inside out. As a result, the folding direction of the sheet-like member 40 at the location corresponding to the center line L is reversed, and the two seam allowances 40A are positioned on the inside of the sheet-like member 40. This forms a bag-shaped fin portion 38 with a portion open. Here, the location of the fin portion 38 that corresponds to the aforementioned center line L will be called the upper end portion 38A of the fin portion 38. The end on the open end side of the fin portion 38 will be called the lower end portion 38B of the fin portion 38.

[0027] As shown in Figure 4, the lower end portion 38B of the fin portion 38 is fixed by sewing to a predetermined position in the second covering portion 20B. When the lower end portion 38B of the fin portion 38 is fixed to the second covering portion 20B, the fin portion 38 is raised on the opposite side from the second covering portion 20B.

[0028] (Operation and effects of this embodiment) Next, the operation and effects of this embodiment will be described.

[0029] As shown in Figures 1 and 2, according to the vehicle seat 10 of this embodiment described above, a fin portion 38 is provided on the cushion trim 20. This fin portion 38 rises from the left rear end 12A of the seat cushion 12 toward the left lower end 14A of the seat back 14 (the left lower end of the back trim 24). When the fin portion 38 is raised in the above direction, a part of the bolt 30 and the weld nut 32 are covered by the fin portion 38. This makes it possible to prevent a part of the bolt 30 and the weld nut 32 from being visible between the left lower end 14A of the seat back 14 and the left rear end 12A of the seat cushion 12.

[0030] Furthermore, the fin portion 38 is formed through the procedure shown in Figures 5 to 7, resulting in a double-layered structure for most of its length, and a quadruple-layered structure in the areas corresponding to the two seam allowances 40A. This makes it easy to maintain the fin portion 38 in the upright position described above. More specifically, for example, even if the fin portion 38 is repeatedly pinched between the lower left end 14A of the seat back 14 and the rear left end 12A of the seat cushion 12 during the reclining operation of the seat back 14, the deformation of the fin portion 38 is suppressed. This makes it easy to maintain the fin portion 38 in the upright position described above.

[0031] In the embodiment described above, an example in which the fin portion 38 has a multi-layer structure was described, but the present invention is not limited to this. Whether or not to make the fin portion 38 a multi-layer structure can be appropriately determined by considering the rigidity and thickness of the members forming the fin portion 38.

[0032] Furthermore, although this embodiment describes an example in which the fin portion 38 is provided on the cushion trim 20 side, the present invention is not limited thereto. For example, the fin portion 38 may be provided on the back trim 24 side.

[0033] Furthermore, although this embodiment describes an example in which a fin portion 38 is provided to suppress the visibility of part of the bolt 30 and the weld nut 32, the present invention is not limited thereto. For example, the configuration of the present invention can also be applied to suppress the visibility of other seat components that affect the appearance design of the vehicle seat.

[0034] Although one embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to the above, and can be implemented in various other ways without departing from the spirit of the invention. [Explanation of Symbols]
