It is said that. The seat back 2 described above has a shell structure that supports the seated person's body in a form of wrapping from the back side (back side) to both sides. Specifically, the seat back 2 described above constitutes the central portion of the front surface of the seat back 2 and supports the body of the seated person from the rear side, and the seat back 2 constitutes both side portions of the front surface of the seat back 2. And a top plate side part 2B that supports the person's body in a form of wrapping from both outsides (both sides).

  More specifically, the seat back 2 described above has a so-called high back type configuration in which a headrest portion 2Aa serving as a headrest portion of a seated person is integrally provided in an upper region of the above-described top plate main portion 2A. In addition, the seat back 2 described above protrudes in such a manner that each of the above-described top plate side portions 2B is curved in a concave shape obliquely toward the front outer side from the left and right sides of the above-described top plate main portion 2A. The body is covered with a shape that wraps around both sides. In the upper region of each of the top plate side portions 2B described above, an overhang portion 2Ba is formed so as to extend largely to the front side of the lower region of the top plate side portion 2B and cover the seated person's head from the side. Has been.

  These projecting portions 2Ba are shaped to project in a concavely curved shape from the left and right sides of the headrest portion 2Aa of the top plate main portion 2A described above toward the front outer side. With the above-described configuration, the seat 1 can form a good personal space in such a manner that the sight of the seated person is blocked from both outsides by the above-described overhang portions 2Ba. The basic structure of the top plate main portion 2A and each top plate side portion 2B of the seat back 2 described above is configured as follows. That is, each has a metal main skeleton inside, and a urethane foam pad is applied to the entire surface of the main skeleton, and a cover made of synthetic leather or fabric so as to cover the entire surface. It is set as the structure which was covered.

  However, only the above-described overhang portions 2Ba of the seat back 2 are configured by the acrylic resin casing 10 having a hollow structure. As shown in FIGS. 2 to 3, each of the housing portions 10 includes a substantially curved plate-shaped surface portion 11 having a surface directed toward the head of the seated person and a substantially curved plate-shaped back surface directed to the back side. The portion 12 is combined to form a hollow closed box shape. The front surface portion 11 and the back surface portion 12 are each formed of an acrylic resin material having transparency or translucency. As shown in FIG. 2, each of the housing portions 10 described above gradually tapers in the thickness between the front surface portion 11 and the back surface portion 12 toward the front outer side in the projecting direction. It is formed in a tapered shape that gets thinner.

  And the speaker unit SU is assembled | attached inside each housing | casing part 10 made into the said hollow shape. These speaker units SU are assembled in a state in which the output opening on the front side with the diaphragm is applied to the inner peripheral surface of the surface portion 11 of each housing unit 10 described above. As shown in FIG. 1, the surface portion 11 of each housing unit 10 to which each speaker unit SU is assembled has innumerable small sound output holes 11 </ b> A for outputting sound output from each speaker unit SU to the outside. It is formed through. With the above configuration, each housing unit 10 is configured to form an enclosure that surrounds the back surface of each speaker unit SU with a hollow sealed structure, as shown in FIGS.

  In addition, films 13 </ b> A and 13 </ b> B, to which colors having different brightness are applied, are attached to each casing 10 on the entire inner peripheral surfaces of the front surface portion 11 and the back surface portion 12 in a laminated manner. Yes. Here, each of the films 13A and 13B described above corresponds to the “design member” of the present invention.

  The film 13 </ b> A laminated on the inner peripheral surface of the front surface portion 11 is configured to have a brighter color than the film 13 </ b> B laminated on the inner peripheral surface of the back surface portion 12. Further, the film 13A laminated on the inner peripheral surface of the surface portion 11 is adhered to the region where each speaker unit SU is assembled, but does not block the formation region of the sound output hole 11A. An infinite number of holes (not shown) are formed at positions corresponding to the shape of the sound output hole 11A. With the above-described configuration, each casing unit 10 has a surface portion 11 that can be seen from the seated person side finished in a color with a relatively small feeling of pressure and a feeling of opening, and a back surface portion 12 that can be seen from the back side of the outside of the vehicle or the rear seat. The structure is finished with a strong shielding color that partitions the space. Therefore, a personal space with a sense of openness can be formed with respect to the seated person by each casing unit 10, and a configuration with a profound feeling can be obtained when each casing unit 10 is viewed from the back side.

  The film 13A laminated on the inner peripheral surface of the front surface portion 11 may be configured to have a darker color than the film 13B laminated on the inner peripheral surface of the back surface portion 12. By adopting such a configuration, each casing unit 10 has a surface portion 11 that can be seen from the seated person side finished in a relatively strong color, and a back surface portion 12 that can be seen from the back side such as the outside of the vehicle or the rear seat. The composition is finished in a relatively open color. Accordingly, each casing unit 10 can form a personal space with a sense of shielding for a seated person, and has a configuration with a feeling of opening when the casing unit 10 is viewed from the back side. be able to.

  Although the detailed illustration is omitted for each of the above-described films 13A and 13B, embossing is performed on the entire region or a partial region thereof. With the above configuration, the design surface by embossing applied to each of the films 13 </ b> A and 13 </ b> B can be projected to the outside of each housing unit 10 to improve the appearance of each housing unit 10. Further, the embossed surface portions of the films 13A and 13B can function as a sound absorbing material that absorbs sound that reverberates within each housing portion 10. By changing the configuration of each of the films 13A and 13B in various ways, the design of the casing unit 10 can be easily changed with a high degree of freedom without changing the configuration of the casing unit 10.

  In summary, the sheet 1 of the present embodiment has the following configuration. That is, a vehicle seat (seat 1) in which a speaker unit (speaker unit SU) is incorporated in the seat. The vehicle seat (seat 1) has a shell structure that supports the seated person's body from the back side to at least one side (both sides). The shell structure has a hollow housing portion (housing portion 10), and a speaker unit (speaker unit SU) is assembled to the housing portion (housing portion 10) to form a housing portion (housing portion). The enclosure 10 encloses the back surface of the speaker unit (speaker unit SU) with a hollow sealed structure. Thus, the enclosure of the speaker unit (speaker unit SU) can be rationally configured without increasing the number of parts by using the configuration of the vehicle seat (seat 1) having the shell structure.

  Further, the housing portion (housing portion 10) is configured as an overhanging portion (overhanging portion 2Ba) that projects to the side of the head of the seated person, and the overhanging portion (the overhanging portion 2Ba) faces the seated person's head side. The speaker unit (speaker unit SU) is assembled to the surface portion (surface portion 11) facing the surface. Thus, by assembling the speaker unit (speaker unit SU) to the surface portion (surface portion 11) of the overhanging portion (the overhanging portion 2Ba) that projects to the side of the head of the seated person in the shell structure, It is possible to obtain a good acoustic effect that wraps around the seated person's ears at a position close to.

  In addition, other structural parts (the parts other than the overhanging part 2Ba formed by the housing part 10 of the top plate side part 2B and the top plate main part 2A) in which the housing part (the housing part 10) forms a shell structure are not. It is set as the structure divided in the communication form. With such a configuration, the speaker unit (speaker unit SU) is supported with a high structural strength by a housing part (housing part 10) partitioned from other structural parts, and is enclosed with an appropriate size. It can be in a state.

  Moreover, the housing | casing part (chassis part 10) comprises the area | region part (overhang | projection part 2Ba) of the edge side used as the taper shape of a shell structure. With such a configuration, the casing unit (casing unit 10) is tapered and has a high structural strength, so that the speaker unit (speaker unit SU) can be supported with a high structural strength. .

  Moreover, while the housing | casing part (housing | casing part 10) is comprised by the member which has transparency or translucency, the design member (film 13A) which has the sound absorption property which can provide the designability outside to a hollow inner peripheral surface , 13B) are provided in a stack. By being set as such a structure, while being able to make a housing | casing part (housing | casing part 10) a structure with a high freedom degree of a design change, the acoustic effect of a housing | casing part (housing | casing part 10) is made. Can be reasonably enhanced.

  Further, the housing portion (housing portion 10) exposes the surface on the front side of the vehicle seat (sheet 1) and the back surface portion exposes the surface on the back side of the vehicle seat (sheet 1). (Back surface portion 12), and the surface portion (front surface portion 11) and the back surface portion (back surface portion 12) have different brightness. In this way, by changing the brightness of the front surface portion (front surface portion 11) and the back surface portion (back surface portion 12) of the housing portion (housing portion 10), the person on each side of the front side and the back side. It can be adjusted so that the feeling of closure and the feeling of opening given to the vehicle are different.

  As mentioned above, although the embodiment of the present invention has been described using one example, the present invention can be implemented in various forms in addition to the above example. For example, the configuration according to the vehicle seat of the present invention can be applied to a seat other than the left seat of an automobile, and is also used for vehicles other than automobiles such as railways, and other vehicles such as airplanes and ships. It can be widely applied to other sheets. In addition, the shell structure in the vehicle seat may be configured to support the occupant's body in a form that wraps from the back side to at least one side, and may not necessarily support the wrapping form on both sides. Good.

  The speaker unit may be provided in any part of the vehicle seat having a shell structure. Specifically, the speaker unit may be assembled so as to emit sound from the back surface portion or the side surface portion in addition to the front surface portion of the vehicle seat having a shell structure.

  Moreover, the hollow housing | casing part by which the said speaker unit is assembled | attached should just be a structure which can function as an enclosure which surrounds the back part of a speaker unit with a hollow sealing structure. In other words, even if the casing has a configuration that has an opening (through hole) that allows the diaphragm of the speaker unit to be exposed to the outside, one rear portion of the speaker unit is attached by assembling the speaker unit. As long as the wall is surrounded by a hollow hermetic structure, it is only necessary to surround the same back surface.

  Further, the design member may be composed of a member having higher sound absorption than the film such as a fabric material or other members. Further, the casing portion may be made of a resin material other than acrylic resin, a metal material, or other materials.
