At least one of each component or part described with a reference number 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 this disclosure includes at least one of the components, such as components or parts, described with a reference number, and the structural parts shown in the drawings.

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

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

As shown in Figure 2, the vehicle seat 1 comprises at least a seat cushion 3, a seat back 5, a recliner 7, and a base mechanism 9. The seat cushion 3 is a part for supporting the buttocks of the seated occupant. The seat back 5 is a part for supporting the back of the seated occupant.

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

Each recliner 7 according to this embodiment also has the function of changing the angle of the seat cushion 3 relative to the vehicle floor panel. 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.

In other words, in the state shown in Figure 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 Figure 5, the seat back 5 functions as a seat back, and the seat cushion 3 functions as a seat cushion.

<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.

The base mechanism 9 according to this embodiment can be switched between a movable mode and a fixed mode. The movable mode allows the position and state of the seat body 2 to be changed relative to the vehicle (see Figures 3 to 8). The fixed mode maintains the position and state of the seat body 2 and prevents it from being changed.

Note that 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 Figure 7, the seat cushion 3 and seat back 5 are in a vertically upright state and in contact with each other.

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 fore-and-aft direction of the vehicle. The second movement mode allows the seat body 2 to rotate around a virtual vertical axis L1 (see Figure 9).

That is, as shown in FIG. 9, the base mechanism 9 is composed of at least a shaft portion 9A, a base plate 9B, and legs 9C. The base plate 9B is a pedestal that supports the seat body 2.

The seat body 2 is connected to the base plate 9B via two recliners 7. Furthermore, 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.

The shaft portion 9A bears the load acting on the seat body 2 and rotatably supports the base plate 9B. In other words, the base plate 9B can rotate around the vertical axis L1 set on the shaft portion 9A.

When the second movable mode is in operation, the base plate 9B is rotatable relative to the shaft portion 9A. When the second movable mode is not in operation, i.e., when the fixed mode is in operation, the base plate 9B is not rotatable relative to the shaft portion 9A.

The shaft 9A is connected to the vehicle so that it can slide in the fore-and-aft direction of the vehicle. Therefore, when the first movable mode is activated, the shaft 9A can slide relative to the vehicle. When the first movable mode is not activated, i.e., when the vehicle is in fixed mode, the shaft 9A cannot slide relative to the vehicle.

The vertical axis L1 is positioned at a position offset in the width direction from at least the center of the width direction of the base plate 9B. Note that the width direction of the base plate 9B is the same as the seat width direction of the vehicle seat 1.

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 activated, the leg portion 9C rotates integrally with the base plate 9B around the vertical axis L1.

<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 components. Examples of "other components" include a table, a partition, a monitor (display), etc.

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 the 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.

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.

As shown in Figure 10, each fixing part 10 has multiple engaging parts 10A and is a rail-like member with these engaging parts 10A arranged in series. Each engaging part 10A is a portion to which other parts can be detachably engaged via an attachment (not shown). Incidentally, each fixing part 10 according to this embodiment is a rail material with a structure similar to that of, for example, an airline rail (registered trademark).

3. Features of the vehicle seat according to this embodiment
The vehicle seat 1 according to this embodiment includes at least one fastening portion 10 to which other components can be detachably fastened. This allows the vehicle user to fasten other components in a position that suits their needs, thereby improving the convenience of the vehicle.

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 underside of the seat cushion 3.

In this 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, for example, with the seat back 5 in an upright, tilted position. 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.

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.

In this vehicle seat 1, the vertical axis L1, which forms the center of rotation of the base plate 9B, is set at a position offset in the width direction from the center of the base plate 9B in the width direction.

As a result, 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, it is possible to avoid interference between the two vehicle seats 1 and place the vehicle seats 1 in a mode that brings them closer to the vehicle wall, as shown in Figures 6 to 8.

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

Therefore, in this embodiment, it is possible to realize modes such as 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).

(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. However, the present disclosure is not limited to this.
