[0024] FIG. 3 is a perspective view showing the internal structure of the ottoman device 3. As shown in FIGS. 1 to 3, the ottoman device 3 is rotatably connected to the lower surface of the pan frame 415 of the seat cushion frame 41. The ottoman device 3 includes a placement portion 5 on which the legs of the occupant are placed, a support portion 6 that supports the placement portion 5 so that the placement portion 5 can move between a storage position (first position) located below the seat cushion 21 and a deployment position (second position) located in front of the seat cushion 21, and a pressing portion 7 that applies a pressing force by linear movement to the placement portion 5 so that the placement portion 5 moves from the storage position to the deployment position (FIG. 1).

[0025] Note that the storage position of the placement portion 5 is a state in which it is located below the seat cushion 21 so as not to interfere with the legs of the user sitting on the vehicle seat 1, and includes, for example, a state (posture) in which the placement surface faces forward. On the other hand, the deployed state of the placement portion 5 is a state in which it is located in front of the seat cushion 21 so that the legs of the user sitting on the vehicle seat 1 can be placed, and includes, for example, a state (posture) in which the placement surface faces upward.

[0026] As shown in FIGS. 1 and 3, the placement portion 5 is configured by attaching a pad 51 made of a cushioning material such as urethane foam to an ottoman frame 50 serving as a skeleton, and further covering the outside thereof with a skin material 52 made of synthetic leather or fabric. The pad 51 is supported on the upper surface corresponding to the placement surface of the ottoman frame 50 and functions as a pressure-receiving portion that receives the load from the legs of the occupant. The skin material 52 integrally covers the placement portion 5 and the device including the support portion 6 and the pressing portion 7 excluding the support bracket 61 described later.

[0027] Figure 4A is a perspective view of the ottoman frame 50, and Figure 4B is a plan view of the ottoman frame 50 of Figure 4A as viewed from below. As shown in Figures 4A and 4B, the ottoman frame 50 includes a base frame (base portion) 53 rotatably connected to the pan frame 415, and a movable frame (movable portion) 54 slidably supported by the base frame 53.

[0028] The base frame 53 extends in the left - right direction and has a base - end frame 531 that constitutes the base - end portion of the base frame 53, a pair of left - and - right side frames 532 that extend in a direction orthogonal to the base - end frame 531 and constitute the left - and - right side portions of the base frame 53, and a tip - end frame 533 that extends in the left - right direction and constitutes the tip - end portion of the base frame 53. The base - end frame 531, the pair of left - and - right side frames 532, and the tip - end frame 533 are integrally joined by welding or the like, and the base frame 53 is formed in a frame shape (lattice shape) as a whole.

[0029] The base - end frame 531 is provided with first rotation - connection portions 531a connected to the rotation - connection portions provided on the lower surface of the pan frame 415 via a rotation axis (not shown) at both ends in the left - right direction. The rotation - connection portion and the first rotation - connection portion 531a are connected via a rotation axis extending in the left - right direction, and the base - end frame 531 is rotatable about this rotation axis. That is, the base frame 53 is rotatable in the up - down direction with respect to the pan frame 415 about a rotation axis extending in the left - right direction.

[0030] The movable frame 54 has a frame body 541 formed in a rectangular plate shape, and a pair of left and right sliding portions 542 configured to be slidable on each of the pair of left and right side frames 532. The frame body 541 is disposed facing the base frame 53 and is formed in substantially the same shape as the overall shape (frame shape) of the base frame 53. A pad 51 is disposed on the upper surface of the frame body 541. An opening 543 is formed in the frame body 541 on the proximal end side. The pair of left and right sliding portions 542 are provided at both left and right ends in the left-right direction of the frame body 541, respectively, and are attached to the frame body 541 so that the frame body 541 can slide in the extending direction of the pair of left and right side frames 532. In the present embodiment, each of the pair of left and right sliding portions 542 is formed in a substantially cylindrical shape that can slide in the extending direction on the rod-shaped side frame 532, and is joined to the frame body 541 via a bracket 544.

[0031] FIG. 5A is a perspective view of the support portion 6 and the pressing portion 7 of the ottoman device 3, and FIG. 5B is a plan view of the support portion 6 and the pressing portion 7 of FIG. 5A as viewed from above. As shown in FIGS. 5A and 5B, the support portion 6 has a support bracket 61 connected to the lower surface of the pan frame 415, a pair of left and right guide portions 62 supported by the support bracket 61, and a connecting bracket 63 that connects the pair of left and right guide portions 62 and the movable frame 54.

[0032] The support bracket 61 is formed such that the support surface (upper surface) 61a is positioned below the lower surface of the pan frame 415 so that the pair of left and right guide portions 62 and the pressing portion 7 can be supported on the upper surface. The support surface 61a of the support bracket 61 is formed substantially parallel to the lower surface of the pan frame 415. As a result, the pair of left and right guide portions 62 slide in the front-rear direction substantially parallel to the pan frame 415, and the pressing portion 7 can apply a pressing force in the front-rear direction substantially parallel to the pan frame 415 to the mounting portion 5.

[0033] The pair of left and right guide portions 62 are respectively provided at both left and right ends in the left-right direction of the support surface 61a of the support bracket 61, and include a cylindrical portion 621 extending in the front-rear direction and a guide rail 622 slidably formed inside the cylindrical portion 621. The cylindrical portion 621 is integrally coupled to the support surface 61a of the support bracket 61 by welding or the like, and the guide rail 622 having a length in the sliding direction longer than that of the cylindrical portion 621 is slidably accommodated inside the cylindrical portion 621.

[0034] The connection bracket 63 is connected to the upper surface of the frame body 541 of the movable frame 54. The connection bracket 63 has second to fourth rotation connection portions 631, 632, 633, and the second to fourth rotation connection portions 631, 632, 633 are provided to extend toward the opening 543 of the frame body 541. The second and third rotation connection portions 631, 632 are provided at both left and right ends, and the tip portions 622a of the pair of left and right guide rails 622 are connected to the second and third rotation connection portions 631, 632 via the opening 543. The second and third rotation connection portions 631, 632 and the tip portions 622a of the pair of left and right guide rails 622 are rotatably connected about a rotation axis extending in the left-right direction.

[0035] The pressing portion 7 is provided between the pair of left and right guide portions 62 on the support surface 61a of the support bracket 61, and includes a drive shaft 71 configured to be able to press the movable frame 54 and an actuator 72 that drives the drive shaft 71. The drive shaft 71 extends in the front-rear direction substantially parallel to the pair of left and right guide portions 62 and is supported by the support surface 61a of the support bracket 61 so as to be movable in the front-rear direction. The tip portion 71a of the drive shaft 71 is rotatably connected to the fourth rotation connection portion 633 of the connection bracket 63 via the opening 543 about a rotation axis extending in the left-right direction. The fourth rotation connection portion 633 of the connection bracket 63 is provided between the second rotation connection portion 631 and the third rotation connection portion 632.

[0036] In this embodiment, the actuator 72 is constituted by a screw motor. The actuator 72 is supported by the support surface 64a of the support bracket 64 such that the rotation axis extends in the left - right direction, and the actuator 72 and the drive shaft 71 are connected via a gear train 73 that converts the power transmitted from the rotation axis of the actuator 72 into the extending direction of the drive shaft 71.

[0037] Next, the operation when the ottoman device 3 provided in the vehicle seat 1 configured as described above is displaced from the stored state to the deployed state will be described. FIG. 6A is a schematic diagram showing the stored state of the ottoman device 3, and FIG. 6B is a schematic diagram showing the deployed state of the ottoman device 3.

[0038] As shown in FIG. 6A, before the user sits on the vehicle seat 1, the ottoman device 3 is in the stored state. That is, the placement portion 5 is located at the storage position. At the storage position, no pressing force acts on the movable frame 54 of the placement portion 5, and the placement portion 5 is in a state (posture) where the sliding direction of the movable frame 54 with respect to the base frame 53 is not in the front - rear direction. This state does not coincide with the moving direction of the drive shaft 71 of the pressing portion 7 or the sliding direction of each guide rail 622 of the pair of left - right guide portions 62.

[0039] When the user sitting on the vehicle seat 1 from this state turns on the drive switch (not shown) of the ottoman device 3, the actuator 72 of the pressing portion 7 operates. When the actuator 72 operates, a pressing force trying to move forward acts on the drive shaft 71, and the drive shaft 71 presses the movable frame 54 via the fourth rotation connection portion 633 of the connection bracket 63 with the pressing force by linear movement.

[0040] When the drive shaft 71 presses the movable frame 54 via the connecting bracket 63, the pressing force due to the linear movement of the drive shaft 71 is changed into a rotational force via the second to fourth moving connection parts 631, 632, 633, and the base frame 53 and the movable frame 54 are rotated upward. When the base frame 53 and the movable frame 54 are rotated upward and the sliding direction of the movable frame 54 with respect to the base frame 53 becomes the same direction (pushable direction) as the pressing direction due to the linear movement of the drive shaft 71 and the sliding directions of the guide rails 622 of the pair of left and right guide parts 62, the rotational force is gradually changed into a pushing force, and the movable frame 54 slides forward with respect to the base frame 53. In this way, the movable frame 54 of the mounting part 5 moves to the deployed position shown in FIG. 6B, and the ottoman device 3 is in the deployed state.

[0041] As described above, by rotating the base frame 53 and the movable frame 54 upward with the pressing force due to the linear movement of the drive shaft 71 and moving the movable frame 54 to the deployed position, the ottoman device 3 excluding the mounting part 5 can be miniaturized.

[0042] Also, at this time, even if the movable frame 54 slides forward with respect to the base frame 53, the drive shaft 71 and the guide rail 622 also move forward in the same manner. Therefore, the device including the support part 6 and the pressing part 7 excluding the mounting part 5 and the support bracket 61 can be integrally covered with the skin material 52. Therefore, it is not necessary to make the skin material 52 longer than necessary, and the appearance performance is improved. In addition, it is preferable to form a slit along the moving direction of the skin material 52 at the connection part between the support bracket 61, the base frame 53, and the pan frame 415.

[0043] According to the present embodiment, the following operational effects can be achieved. (1) The vehicle seat 1 according to this embodiment includes a seat cushion 21 on which a user sits and an ottoman device 3 connected to the seat cushion 21 (Fig. 1). The ottoman device 3 includes a placement portion 5 on which the legs of the user sitting on the seat cushion 21 are placed, and a support portion 6 that supports the placement portion 5 so that the placement portion 5 can move between a storage position located below the seat cushion 21 (Fig. 6A) and a deployment position located in front of the seat cushion 21 (Fig. 6B). The ottoman device 3 further includes a pressing portion 7 that applies a pressing force by linear movement to the placement portion 5 so that the placement portion 5 moves from the storage position to the deployment position (Figs. 3 and 5A).

[0044] With this configuration, the ottoman device 3 excluding the placement portion 5 can be miniaturized without using a large link mechanism such as a four-bar link mechanism. Therefore, the interior of the vehicle in which the vehicle seat 1 is installed can be effectively utilized.

[0045] (2) In the above vehicle seat 1, the placement portion 5 has a base frame 53 that is rotatably connected to the seat cushion 21 in the vertical direction, and a movable frame 54 that is supported by the base frame 53 so as to slide along the base frame 53 (Fig. 3). The support portion 6 supports the movable frame 54 so that it can rotate freely in the vertical direction and slide freely in the front-rear direction (Fig. 5A). The pressing portion 7 presses the movable frame 54 located in the storage position forward, thereby rotating the base frame 53 and the movable frame 54 upward, and sliding the movable frame 54 forward toward the deployment position along the upward-rotated base frame 53 (Figs. 6A and 6B).

[0046] With this configuration, the placement portion 5 can be moved from the storage position to the deployment position simply by applying a pressing force by linear movement to the movable frame 54, and the ottoman device 3 excluding the placement portion 5 can be miniaturized. In addition, since the configuration for moving the placement portion 5 can be composed of a simple mechanism, maintenance, repair, etc. become easy.

[0047] (3) In the vehicle seat 1 described above, the pressing portion 7 includes a drive shaft 71 that is supported so as to be linearly movable toward the mounting portion 5, and an actuator 72 that drives the drive shaft 71 (FIGS. 5A and 5B). With this configuration, the pressing portion can be configured with a small number of components.

[0048] The above embodiment can be modified into various forms. Hereinafter, modification examples will be described.

[0049] FIG. 7 is a cross-sectional view showing a modification example of the ottoman device 3 according to the present embodiment. In the above embodiment, the pressing portion 7 of the ottoman device 3 has been described using the drive shaft 71 and the actuator 72. However, as shown in FIG. 7, a configuration using a cylinder 75 having a cylinder piston 74a and a cylinder tube 74b may be used instead. As the cylinder 75, for example, a gas damper can be used. A configuration may be adopted in which the released state of the gas damper is set as the deployed state of the mounting portion 5, and the stored state of the mounting portion 5 is set by locking the compressed state of the gas damper. To lock the gas damper in the compressed state, a configuration may be adopted in which a user sitting on the seat device 2 presses the mounting portion 5 with their leg and moves it to the storage position to lock it, or a configuration may be adopted in which the user manually pulls back a cable or the like to move it to the storage position to lock it.

[0050] In the above embodiment, the vehicle seat has been described. However, it may be used for seats other than vehicles, for example, seats for vehicles such as airplanes, or for sofas, massage chairs, etc. used in houses and the like. Further, although the vehicle seat 1 of the present embodiment is preferably used for the rear seat, in the case of an autonomous vehicle, the vehicle seat 1 may be used for the driver's seat or the passenger seat.

[0051] The above description is merely an example, and the present invention is not limited to the above-described embodiment and modification examples as long as the features of the present invention are not impaired. It is also possible to arbitrarily combine one or more of the above embodiment and modification examples, and it is also possible to combine the modification examples with each other.
