Summary of the Invention

Problems to be Solved by the Invention

[0004] In the partition device for a seat described in Patent Document 1, the partition is a structure composed of a single plate material that is three-dimensionally curved. Therefore, the mounting portion of the speaker has a concave shape facing inward, resulting in a decrease in the design property on the rear side (outer side) of the partition. The present disclosure discloses an example of a "partition device for a seat to which functional components such as a speaker can be attached" in view of this point.

Means for Solving the Problems

[0005] The partition device disposed on the upper side of the seat back (1) preferably includes at least one of the following constituent elements, for example. That is, the constituent element is at least a shade member (11) that covers the upper side of the seat back (1), and a mounting member (12) disposed inside the shade member (11), the mounting member (12) being provided with mounting portions (12A, 12B) for the functional component (13).

[0006] As a result, in the partition device for the sheet, the shape of the shade member (11) is not affected (constrained) by the mounting parts (12A, 12B) of the functional component (13). Consequently, it may be possible to obtain a partition device that can accommodate various functional components (13) without significantly compromising the aesthetic appeal.

[0007] The partition device for the sheet may have, for example, the following configuration. In other words, it is desirable that the shade member (11) and the mounting member (12) are connected and integrated. This may make it possible to improve the rigidity of the sheet partition device compared to a sheet partition device composed of only one shade section.

[0008] Furthermore, it is desirable that the cross-sectional shape of the mounting member (12) be approximately C-shaped or U-shaped, convex toward the inside of the shade member (11). This can further improve the rigidity of the sheet partition device.

[0009] Furthermore, the shade member (11) can cover not only the upper rear side of the seat back (1), but also one and the other sides in the seat width direction at the top of the seat back (1). Moreover, when the functional component (13) is an electrically operated functional component, it is desirable that the mounting member (12) on the shade member (11) side has a mounting portion (12G) on which the control board (13C) of the functional component (13) is mounted.

[0010] As a result, the wiring and control board (13C) attached to the functional component (13) can be placed in a location that is not visible from the outside, that is, in the space between the mounting member (12) and the shade member (11). This improves the aesthetic design of the seat partition device and also helps to prevent seated persons from accidentally touching the control board (13C), etc.

[0011] Furthermore, it is desirable that vibration-dampening material (15) is placed in at least a portion of the space formed between the shade member (11) and the mounting member (12) to suppress vibrations of the shade member (11) and the mounting member (12).

[0012] As a result, the partition device for the sheet may be able to enhance the effect of sound leakage to the outside and suppress the generation of unpleasant vibration noises, etc., without significantly compromising the aesthetic appeal.

[0013] Incidentally, the symbols in each of the parentheses above are just examples showing the correspondence with the specific configurations etc. described in the embodiments described later, and this disclosure is not limited to the specific configurations etc. indicated by the symbols in the parentheses above.

[Modes for carrying out the invention]

[0015] The following "Embodiments of the Invention" are examples of embodiments that fall within the technical scope of this disclosure. In other words, the features defining the invention as described in the claims are not limited to the specific configurations and structures shown in the embodiments below.

[0016] This embodiment is an example in which a partition device for a seat according to the present disclosure (hereinafter abbreviated as a partition device) is applied to a seat mounted on a vehicle such as a car (hereinafter referred to as a vehicle seat).

[0017] Arrows, slashes, etc. indicating directions attached to each figure are described to facilitate understanding of the relationships between the figures and the shapes of members or parts. Therefore, the partition device is not limited to the directions attached to each figure.

[0018] The directions shown in each figure are the directions in the state where the vehicle seat according to this embodiment is assembled to the vehicle. The figure with slashes does not always show a cross-sectional view. At least one member or part provided with a reference numeral and described is provided at least one, unless otherwise specified such as "one".

[0019] That is, when there is no such specification as "one", two or more of such members may be provided. The partition device shown in the present disclosure includes at least one of the components such as members or parts provided with a reference numeral and described, and the structural parts shown in the drawings.

[0020] (First Embodiment) (1. Outline of Partition Device) As shown in FIG. 2, the partition device 10 according to this embodiment is used by being mounted on the upper side of the seat back 1. Specifically, the partition device 10 is for simply dividing the head of the seated person from the surroundings so as to cover the head of the seated person.

[0021] The partition device 10 according to this embodiment is mounted and fixed to a headrest stay (not shown). The headrest stay is a member that connects and fixes the headrest 2 to the seat back 1.

[0022] The headrest 2 is provided at the upper end of the seat back 1 and is a component that supports the back of the occupant's head. The seat back 1 is one of the components that make up a vehicle seat and is the part that supports the occupant's back.

[0023] <2. Partition Device Details> As shown in Figure 3, the partition device 10 includes at least a shade member 11, a mounting member 12, and a bracket 14, etc.

[0024] <Shade components> The shade member 11 is a covering member that covers at least the upper rear side of the seat back 1. In this embodiment, as shown in Figure 2, the shade member 11 can cover not only the upper rear side but also one side and the other side in the width direction of the seat at the top.

[0025] Specifically, as shown in Figure 1, the shade member 11 has a first covering portion 11A, a second covering portion 11B, a third covering portion 11C, etc., and is configured in a roughly C-shape or U-shape that opens towards the front of the seat. The front of the seat refers, for example, to the side of the seated person's head or headrest 2 relative to the shade member 11.

[0026] The first cover portion 11A is the part that covers the rear of the headrest 2. The second cover portion 11B is the part that covers the left side of the headrest 2. The third cover portion 11C is the part that covers the right side of the headrest 2. The first cover portion 11A, the second cover portion 11B, and the third cover portion 11C are integrally molded as a single piece from a resin such as polycarbonate.

[0027] <Mounting components> The mounting member 12 is a member positioned on the inside of the shade member 11 (in this embodiment, on the front side of the seat). The inside of the shade member 11 refers, for example, to the side of the seated person's head or the side of the headrest 2 relative to the shade member 11.

[0028] The mounting member 12 is provided with mounting portions 12A and 12B for the functional component 13. As shown in Figure 4, the mounting member 12 according to this embodiment has a front portion 12A, a first side portion 12C and a second side portion 12D, etc., and is configured in a roughly C-shape or U-shape that opens towards the front of the seat.

[0029] Furthermore, a mounting portion 12A is provided on the first side portion 12C, and a mounting portion 12B is provided on the second side portion 12D. The front portion 12A, the first side portion 12C, and the second side portion 12D are integrally molded as a single piece from a resin such as polycarbonate.

[0030] Furthermore, as shown in Figure 5, the cross-sectional shape of the mounting member 12 is configured to be roughly C-shaped or U-shaped, convex toward the inside of the shade member 11 (in this embodiment, toward the front side of the sheet).

[0031] Specifically, rib-like protrusions 12E and 12F are provided on the upper and lower ends of the front portion 12A, the first side portion 12C, and the second side portion 12D. These protrusions 12E and 12F project toward the rear side of the sheet, that is, toward the outside of the shade member 11. The outside of the shade member 11 refers to the side opposite to the inside of the shade member 11, with the shade member 11 in between.

[0032] The term "lower end" refers to the part of the mounting member 12 closest to the upper end of the seat back 1. The term "upper end" refers to the side opposite the "lower end" with respect to the front portion 12A. The protrusions 12E and 12F are also integrally molded from resin along with the front portion 12A, etc.

[0033] Functional components 13 are attached to the mounting sections 12A and 12B. Functional components 13 include, for example, pads such as cushioning material, blowers (including air vents), microphones, and speakers.

[0034] In other words, the functional component 13 is a device that realizes additional functions different from the seat's original function of "sitting." In this embodiment, the functional component 13 is an electrical functional component such as a speaker.

[0035] Therefore, the functional component 13 will also be referred to as speaker 13 below. As shown in Figure 1, the right speaker 13A is mounted on the mounting part 12A, and the left speaker 13A is mounted on the mounting part 12A.

[0036] In this embodiment, the mounting sections 12A and 12B are configured in a planar shape, as shown in Figure 4, because the speaker 13 is mounted on them. The normal direction of the planes constituting the mounting sections 12A and 12B is generally directed towards the area where the ears of a seated person are located.

[0037] As shown in Figure 6, the mounting portion 12G on the shade member 11 side of the mounting member 12 is provided on which the control board 13C is mounted. The control board 13C is, for example, an electrical circuit board having a drive circuit for driving the speaker 13.

[0038] <bracket> The bracket 14 is a mounting member for attaching and securing the partition device 10 to the seat back 1. That is, as shown in Figure 1, the shade member 11 and the mounting member 12 are connected and integrated.

[0039] The bracket 14 is fixed to the shade member 11. The bracket 14 is attached and fixed to the headrest stay. The shade member 11 and the mounting member 12 are connected by mechanical fasteners such as pop rivets. Similarly, the bracket 14 is also fixed to the shade member 11 by the same mechanical fasteners.

[0040] <3. Features of the partition device according to this embodiment> The partition device 10 according to this embodiment includes a shade member 11 and a mounting member 12 on which mounting portions 12A and 12B for functional components 13 are provided. As a result, in the partition device 10, the shape of the shade member 11 is not affected (constrained) by the mounting portions 12A and 12B of the functional components 13.

[0041] Furthermore, in the partition device 10, it becomes possible to mount the speaker 13, which is an example of a functional component, so as to face the ears of the seated person, while also achieving both high design quality and acoustic performance.

[0042] Furthermore, the partition device 10 can be adapted to various specifications at low cost by replacing the mounting member 12. In other words, it is possible to obtain a partition device 10 that can accommodate various functional components 13 without significantly compromising its aesthetic appeal.

[0043] In this partition device 10, the shade member 11 and the mounting member 12 are connected and integrated. This makes it possible to improve the rigidity of the partition device 10 compared to a partition device 10 composed of only one shade section.

[0044] Furthermore, the cross-sectional shape of the mounting member 12 is roughly C-shaped or U-shaped, convex toward the inside of the shade member 11. This can further improve the rigidity of the partition device 10.

[0045] Furthermore, in the partition device 10, the shade member 11 covers the upper rear side, one side in the sheet width direction, and the other side, and the mounting member 12 on the side of the shade member 11 is provided with a mounting portion 12G for the control board 13C.

[0046] As a result, the wiring and control board 13C attached to the functional component 13 can be placed in a location that is not visible from the outside, that is, in the space between the mounting member 12 and the shade member 11. This improves the aesthetic design of the partition device 10 and also prevents seated persons from accidentally touching the control board 13C, etc.

[0047] (Second Embodiment) As shown in Figure 7, the partition device 10 according to this embodiment has a vibration suppression material 15 placed in at least a portion of the space formed between the shade member 11 and the mounting member 12.

[0048] The vibration-dampening material 15 is expected to have the effect of suppressing vibrations of the shade member 11 and the mounting member 12. Specifically, it is a sound-absorbing material such as urethane, a vibration-damping material such as a weight, or an damper such as a damper. In this embodiment, urethane is filled and arranged in the above space.

[0049] As a result, the partition device 10 according to this embodiment can enhance the effect of preventing sound leakage to the outside without significantly reducing the aesthetic appearance, and can also suppress the generation of unpleasant vibration noises.

[0050] (Other embodiments) The shade member 11 according to the above embodiment had a substantially C-shaped or U-shaped configuration that covered not only the upper rear side of the seat back 1 but also one and the other sides in the width direction of the upper part of the seat. However, the disclosure is not limited thereto. That is, the disclosure may also include, for example, a flat plate-shaped shade member 11 that covers only the upper rear side.

[0051] In the above-described embodiment, the shade member 11 and the mounting member 12 were connected, and the shade member 11 and the mounting member 12 were fixed to the seat back 1 via the shade member 11. However, the present disclosure is not limited thereto.

[0052] In other words, the disclosure may be, for example, a configuration in which the shade member 11 and the mounting member 12 are fixed to the seat back 1, or a configuration in which the shade member 11 and the mounting member 12 are connected and a bracket 14 is provided on the mounting member 12.

[0053] In the embodiments described above, the cross-sectional shape of the mounting member 12 was configured to be approximately C-shaped or approximately U-shaped. However, the disclosure is not limited thereto. That is, the disclosure may also include a mounting member 12 having a cross-sectional shape such as approximately L-shaped or I-shaped.

[0054] In the above-described embodiment, since the functional component 13 was an electrical functional component such as a speaker, a mounting portion 12G for the control board 13C was provided on the side of the mounting member 12 facing the shade member 11. However, this disclosure is not limited thereto. That is, the disclosure may also include, for example, a configuration in which the mounting portion 12G is eliminated.

[0055] In the above-described embodiment, the shade member 11 and the mounting member 12 were manufactured separately, and then the shade member 11 and the mounting member 12 were integrated using mechanical fasteners. However, the present disclosure is not limited thereto.

[0056] The mounting portions 12A and 12B in the above-described embodiment were configured in a planar shape. However, the disclosure is not limited thereto. That is, the disclosure may be configured, for example, in an uneven or convex shape.

[0057] The partition device 10 according to the above embodiment was configured to surround the headrest 2. However, the disclosure is not limited thereto. That is, the disclosure is also applicable to seatbacks that do not have a headrest, for example, so a partition device that covers the upper end 4 of the seatback may also be applicable.

[0058] In the embodiments described above, the vehicle seat according to this disclosure was applied to a vehicle. However, the application of the invention disclosed herein is not limited to this. That is, the disclosure can be applied, for example, to seats used in vehicles such as railway cars, ships and aircraft, as well as to stationary seats used in theaters, homes, etc.

[0059] Furthermore, this disclosure is not limited to the embodiments described above, but is sufficient to be consistent with the intent of the disclosures described in the embodiments described above. Therefore, it may be a configuration in which at least two of the embodiments described above are combined, or a configuration in which any of the illustrated components or components described with reference numerals in the embodiments described above are omitted.
