[0009] The following "embodiments of the invention" are examples of embodiments that fall within the technical scope of the present disclosure. In other words, the invention-specific matters described in the claims are not limited to the specific configurations and structures shown in the following embodiments.

[0010] This embodiment is an example in which a vehicle seat according to the present disclosure is applied to a seat (hereinafter referred to as a vehicle seat) mounted on a vehicle such as a so-called "wabbox car." The directions shown in each drawing are directions when the vehicle seat according to this embodiment is assembled in a vehicle.

[0011] Arrows and other directional arrows in each figure are provided to facilitate understanding of the relationships between the figures and the shapes of components or parts, etc. Therefore, the vehicle seat is not limited to the directions indicated in each figure.

[0012] At least one of a component or part that is described with a reference numeral is provided unless otherwise specified, such as "one." In other words, unless otherwise specified, such as "one," two or more components may be provided. The vehicle seat disclosed in the present disclosure includes at least one of the components, such as the components or parts, that are described with a reference numeral and the structural parts shown in the drawings.

[0013] (First embodiment) <1. Overview of vehicle seats> The vehicle seat 1 according to this embodiment is applied to a vehicle seat installed behind the driver's seat Ds, as shown in Fig. 1. Specifically, the vehicle seat 1 is applied to a second-row bench seat 1A and a third-row bench seat 1B.

[0014] In this embodiment, the second-row bench seat 1A and the third-row bench seat 1B have the same configuration. Hereinafter, the vehicle seat 1 is intended to refer to either one of the bench seats 1A and 1B, or to both bench seats 1A and 1B collectively.

[0015] As shown in Fig. 2, the vehicle seat 1 includes at least a seat cushion 3, a seat back 5, a recliner 7, and a base mechanism 9. The seat cushion 3 is a portion for supporting the buttocks of a seated occupant. The seat back 5 is a portion for supporting the back of the seated occupant.

[0016] <Licranana> The recliner 7 is a mechanism that changes the angle of the seat back 5 relative to the seat cushion 3. The recliners 7 are provided on the lower end sides of one end and the other end of the seat back 5 in the seat width direction.

[0017] Each recliner 7 according to this embodiment also has the function of changing the angle of the seat cushion 3 relative to the floor panel of the vehicle. Therefore, in this embodiment, as shown in Figure 6, it is possible to place the seat cushion 3 in an upright position and the seat back 5 in a horizontal position.

[0018] That is, in the state shown in Fig. 6, the seat back 5 functions as a seat cushion, and the seat cushion 3 functions as a seat back. Incidentally, in the state shown in Fig. 5, the seat back 5 functions as a seat back, and the seat cushion 3 functions as a seat cushion.

[0019] <Base mechanism> The base mechanism 9 is a mechanism for fixing the seat body 2 to the vehicle. The seat body 2 according to this embodiment refers to a portion of the vehicle seat 1 that includes at least the seat cushion 3 and the seat back 5.

[0020] The base mechanism 9 according to this embodiment can be switched between a movable mode and a fixed mode. The movable mode is a mode in which the position and state of the seat body 2 can be changed relative to the vehicle (see FIGS. 3 to 8). The fixed mode is a mode in which the position and state of the seat body 2 is maintained and cannot be changed.

[0021] The position of the seat body 2 refers to the position of the seat body 2 relative to the vehicle, the orientation of the seat body 2, etc. The state of the seat body 2 refers to the state of the seat cushion 3 and the seat back 5. For example, in FIG. 7, the seat cushion 3 and the seat back 5 are in a vertically erect state so as to be in contact with each other.

[0022] The base mechanism 9 can operate in two movement modes: a first movement mode and a second movement mode. The first movement mode allows the seat body 2 to slide in the longitudinal direction of the vehicle. The second movement mode allows the seat body 2 to rotate around a virtual vertical axis L1 (see FIG. 9).

[0023] 9, the base mechanism 9 is configured to include at least a shaft portion 9A, a base plate 9B, and legs 9C, etc. The base plate 9B is a pedestal that supports the seat body 2.

[0024] The seat body 2 is connected to the base plate 9B via two recliners 7. The two recliners 7 are slidably connected to the base plate 9B. Therefore, the seat body 2 can slide relative to the base plate 9B, i.e., the base mechanism 9.

[0025] The shaft portion 9A receives the load acting on the seat body 2 and rotatably supports the base plate 9B. That is, the base plate 9B is rotatable about a vertical axis L1 set on the shaft portion 9A.

[0026] When the second movable mode is executed, the base plate 9B is rotatable relative to the shaft portion 9A. When the second movable mode is not executed, that is, when the fixed mode is executed, the base plate 9B is not rotatable relative to the shaft portion 9A.

[0027] The axle 9A is connected to the vehicle so as to be slidable in the longitudinal direction of the vehicle. Therefore, when the first movable mode is executed, the axle 9A is slidable relative to the vehicle. When the first movable mode is not executed, i.e., when the vehicle is in the fixed mode, the axle 9A is not slidable relative to the vehicle.

[0028] The vertical axis L1 is positioned at a position that is shifted in the width direction from at least the center of the width direction of the base plate 9B. The width direction of the base plate 9B coincides with the seat width direction of the vehicle seat 1.

[0029] The leg portion 9C is integrated with the base plate 9B and cooperates with the shaft portion 9A to bear the load acting on the seat body 2. Therefore, when the second movable mode is executed, the leg portion 9C rotates integrally with the base plate 9B around the vertical axis L1.

[0030] <2.Fixed part> As shown in Fig. 2, the vehicle seat 1 is provided with at least one (in this embodiment, multiple) fixing parts 10. These fixing parts 10 are fasteners that allow the user to detachably fix other members. "Other members" include, for example, a table, a partition, a monitor (display), etc.

[0031] The fixing portion 10 is provided on a portion of the vehicle seat 1 other than the seat surface 2A. The seat surface 2A refers to a portion of the vehicle seat 1 that may come into contact with an occupant when seated. Specifically, the surface of the seat cushion 3 and the surface of the seat back 5 correspond to the seat surface 2A.

[0032] In the vehicle seat 1 according to this embodiment, at least one fixing portion 10 is provided on each of the rear surface of the seat cushion 3, the rear surface of the seat back 5, and the upper surface of the base plate 9B.

[0033] As shown in Fig. 10, each fixing portion 10 has a plurality of engaging portions 10A, and is a rail-like member in which the engaging portions 10A are arranged in series. Each engaging portion 10A is a portion to which another member can be detachably engaged via an attachment (not shown). Incidentally, each fixing portion 10 according to this embodiment is a rail material having a structure similar to that of, for example, an airline rail (registered trademark).

[0034] 3. Features of the vehicle seat according to this embodiment The vehicle seat 1 according to this embodiment includes at least one fixing portion 10 to which other members can be detachably fixed. This allows the vehicle user to fix other members in a position that suits their needs. This in turn improves the convenience of the vehicle.

[0035] Furthermore, each fixing portion 10 is provided on a portion of the vehicle seat 1 other than the seat surface 2A. Therefore, for example, as shown in Fig. 6, when the seat cushion 3 is in an upright position and the seat back 5 is in a horizontal position, the user can use the fixing portion 10 provided on the back surface of the seat cushion 3.

[0036] In the vehicle seat 1, the seat body 2 is connected to the base plate 9B via two recliners 7. This allows the user to fasten other components to the fixing part 10 with the seat back 5 in an upright tilted position, for example. Therefore, as shown in Figures 4 and 5, the user can also use the fixing part 10 with the seat back 5 in an upright tilted position.

[0037] In Figure 4, the seat cushion 3 for the second row is in a vertically upright position, the seat back 5 for the second row is in a horizontal position, the seat cushion 3 for the third row is in a horizontal position and in contact with the seat back 5 for the second row, and the seat back 5 for the third row is in an upright position at an angle.

[0038] In the vehicle seat 1, the position of the vertical axis L1 that forms the center of rotation of the base plate 9B is set at a position that is shifted in the width direction from the center in the width direction of the base plate 9B.

[0039] This makes it possible, when the vehicle seat 1 is rotated so that the seat width direction of the vehicle seat 1 coincides with the fore-and-aft direction of the vehicle, to avoid interference between the two vehicle seats 1 and place the vehicle seats 1 in a mode that moves them closer to the vehicle wall, as shown in Figures 6 to 8.

[0040] Furthermore, the seat body 2 of the vehicle seat 1 is connected to a base plate 9B via two recliners 7, and the recliners 7 are slidably connected to the base plate 9B.

[0041] Therefore, in this embodiment, it is possible to realize a mode in which the seat cushion 3 is in an upright position and the seat back 5 is in a horizontal position (see Figure 6), and a mode in which the seat cushion 3 is in a horizontal position and the seat back 5 is in an upright position (see Figures 5 and 8).

[0042] (Other embodiments) In the above-described embodiment, the position of the vertical axis L1 is set at a position shifted in the width direction from the center in the width direction of the base plate 9B, but the present disclosure is not limited to this.

[0043] That is, the disclosure may be, for example, a configuration in which the position of the vertical axis L1 is set at a position shifted in the fore-and-aft direction from the center of the base plate 9B in the fore-and-aft direction, or a configuration in which the position of the vertical axis L1 is set at a position shifted from the center of the base plate 9B.

[0044] In the above-described embodiment, an airline rail (registered trademark) is used as the fixing portion 10. However, the present disclosure is not limited to this. That is, in the present disclosure, for example, the fixing portion may be formed by a plurality of holes provided in the vehicle seat 1, and engaging portions that can be detachably fitted into the holes may be provided on another member.

[0045] In the above-described embodiment, a rail member is used as the fixing portion 10. However, the present disclosure is not limited to this. That is, in the present disclosure, for example, the fixing portion may be configured by a hook provided on a frame that forms the framework of the vehicle seat 1.

[0046] In the vehicle seat 1 according to the above-described embodiment, the fixing portions 10 are provided on the rear surface of the seat cushion 3, the rear surface of the seat back 5, and the upper surface of the base plate 9B. However, the present disclosure is not limited to this.

[0047] In other words, the disclosure may be, for example, a configuration in which fixing portions 10 are provided on the sides of the seat back 5 and the seat cushion 3 in addition to the back surface of the seat back 5, or a configuration in which fixing portions 10 are provided only on the back surface of the seat back 5.

[0048] In the above-described embodiment, the two recliners 7 are slidably connected to the base plate 9B. However, the present disclosure is not limited to this. That is, the present disclosure may be configured such that the two recliners 7 are fixed to the base plate 9B, for example.

[0049] In the above-described embodiment, the layout of the vehicle seat 1 is illustrated in Figures 3 to 8, and the driver's seat Ds is configured to be slidable and rotatable. However, the present disclosure is not limited to this. That is, the present disclosure may also be configured such that the driver's seat Ds cannot be rotated, for example.

[0050] In the above-described embodiment, the vehicle seat according to the present disclosure is applied to a bench seat. However, the present disclosure is not limited to this. That is, the present disclosure may also be applied to, for example, a single-seat seat.

[0051] In the above-described embodiment, the vehicle seat according to the present disclosure is applied to a vehicle. However, the application of the invention disclosed in this specification is not limited thereto. That is, the present disclosure can also be applied to seats used in vehicles such as railway cars, ships, and aircraft, as well as stationary seats used in theaters, homes, etc.

[0052] Furthermore, the present disclosure is not limited to the above-described embodiments as long as it conforms to the spirit of the disclosure described in the above-described embodiments. Therefore, the present disclosure may be a configuration in which at least two of the above-described embodiments are combined, or a configuration in which any of the components illustrated or described with reference numerals in the above-described embodiments is eliminated.
