Description

[Technical Field]

[0001] The present invention relates to a vehicle seat, and more particularly to a vehicle seat provided with an ottoman. [Background technology]

[0002] Vehicle seats equipped with ottomans that can improve the comfort of passengers traveling in vehicles have become widespread. The ottoman is a support member that supports the lower legs (calves) of a passenger seated in a vehicle seat from below, thereby reducing the burden on the passenger's legs. In recent years, vehicle seats equipped with footrests have become popular. A footrest is a support member on which the soles of the feet of a vehicle occupant can rest, and like an ottoman, it reduces the burden on the occupant's legs and improves comfort.

[0003] Patent Document 1 discloses a vehicle seat equipped with a calf support portion that supports the calves of an occupant and a footrest on which the soles (heels) of the occupant's feet can be placed. The footrest can rotate between a stored state in which it extends substantially parallel to the calf support portion and an unfolded state in which it unfolds perpendicular to the calf support portion. Therefore, when the footrest is in the unfolded state, the vehicle seat can simultaneously support the calves and soles of the occupant's feet. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2013-530076 Summary of the Invention [Problem to be solved by the invention]

[0005] Although the technology described in Patent Document 1 can reduce the burden on the legs of an occupant sitting in a vehicle seat and improve comfort, there is still room for further improvement in occupant comfort. Also, there are concerns that attaching an ottoman and a footrest to a vehicle seat will increase the size and weight of the vehicle seat.

[0006] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a vehicle seat that can reduce the burden on the occupant's legs by using an ottoman and footrest, thereby further improving comfort, while also preventing the seat from becoming larger and heavier. [Means for solving the problem]

[0007] The above problem is solved by the vehicle seat of the present invention, which provides a vehicle seat including a seat cushion and an ottoman, wherein the ottoman has an ottoman main body and a foot rest portion on which the soles of the occupant's feet can be placed, the ottoman main body has a base end connected to the seat cushion and a tip end located opposite the base end, the foot rest portion is connected to both sides of the ottoman main body in the seat width direction and has left and right extension portions that extend from the tip end in a tip direction from the base end of the ottoman main body towards the tip end, and sole contact portions that connect the tip end portions of the left and right extension portions and can come into contact with the soles of the occupant's feet, and an opening is formed between the tip end of the ottoman main body and the sole contact portion.

[0008] According to the above configuration, the ottoman has an ottoman body and a leg rest portion on which the soles of the occupant's feet can be placed, and an opening is formed between the ottoman body and the sole-contact portion of the sole-receiving portion. Therefore, an occupant sitting in the vehicle seat can place their plantar arch (arch) on the sole-contact portion by inserting their heel from the front to the rear of the opening. This reduces the burden on the occupant's legs and further improves comfort. Furthermore, since the sole-contact portion only needs to have a shape and dimensions that allow the occupant's arch to be placed thereon, it is possible to prevent the vehicle seat from becoming larger and heavier.

[0009] In addition, the foot rest portion can slide between a storage position in which it is stored in the ottoman body and an expanded position in which it protrudes from the ottoman body toward the tip of the ottoman body, and the left and right extension portions and the foot contact portion preferably form an approximately U-shape. According to the above configuration, the entire vehicle seat can be made compact by storing the leg rest portion in the ottoman body, and since the leg rest portion forms an approximately U-shape, it is possible to suppress an increase in the weight of the vehicle seat.

[0010] In addition, the ottoman main body is rotatably connected to the seat cushion via a pivot shaft member extending in the seat width direction, and when the tip direction of the ottoman main body faces downward, the left and right extensions are positioned forward of the pivot shaft member. According to the above configuration, by rotating the ottoman body via the pivot shaft, it is possible to effectively prevent luggage placed on the seating surface of the seat cushion from falling off while traveling. In addition, it is possible to prevent the left and right extensions from interfering with the pivot shaft while preventing the ottoman from becoming too large.

[0011] In addition, the ottoman body has a leg rest support member that supports the leg rest, and the extension portion has a flange at the end opposite the sole contact portion, and the flange abuts against the leg rest support member when the leg rest is positioned in the extended position. According to the above configuration, when the leg rest is in the deployed position, the flange abuts against the leg rest support member, thereby improving the connection strength of the leg rest to the ottoman body.

[0012] In addition, the leg rest support member has a support wall portion that supports the extension portion, and a front wall portion and a rear wall portion that are located at both ends of the support wall portion in the front-to-rear direction and face each other, and the front wall portion and the rear wall portion face the extension portion in the front-to-rear direction when the tip direction of the ottoman main body faces downward. According to the above configuration, since the footrest support member has a front wall portion and a rear wall portion, the strength of the footrest support member in the front-to-rear direction can be improved, and the footrest can be stably supported. Also, it is possible to prevent the occupant from feeling a foreign body sensation due to the occupant's legs coming into contact with the extension member.

[0013] In addition, the seat cushion is rotatably connected to the seat cushion and is fixed to the floor of the vehicle via a folding link that causes the seat cushion to fold forward, and the footrest support member has a position regulating member that regulates the footrest to a position between the deployed position and the stored position, and the position regulating member has a locking member that is biased in a direction to engage with a locking portion provided on the extension portion, and when the footrest abuts against the floor when positioned in the deployed position, the restriction by the position regulating member is released and the footrest is displaced toward the stored position. According to the above configuration, the position of the leg rest can be restricted by engaging the locking member with the locked portion, and the leg rest can be displaced to the stowed position when the seat cushion is tilted forward. This allows the occupant to place the soles of their feet on the leg rest with peace of mind, and prevents the leg rest from interfering with the tilting of the seat cushion.

[0014] In addition, the seat cushion frame of the seat cushion has left and right cushion side frames and a pan frame connecting the front of the left and right cushion side frames, and when the leg rest portion is located in the storage position, the upper end of the extension portion is located above the upper end of the pan frame and below the upper end of the ottoman main body. According to the above configuration, the leg rest portion can be efficiently stored in the ottoman body, making it possible to make the ottoman compact.

[0015] In addition, the ottoman may have a covering material that can transition between a covered state in which the leg rest portion located in the stored position is covered together with the ottoman body, and an open state in which the leg rest portion located in the deployed position is exposed. According to the above configuration, the leg rest portion positioned in the storage position can be covered with the covering material, which makes it possible to improve the design of the vehicle seat.

[0016] The seat cushion is fixed to a slide rail device that slides the seat cushion in the front-rear direction via a lifting device that raises and lowers the seat cushion, The foot rest may be disposed above the slide rail device when the lifting device lowers the seat cushion. According to the above configuration, even when the seat cushion is lowered by the lifting device, the soles of the occupant's feet can be placed on the leg rest portion, thereby reducing the burden on the occupant's legs and improving comfort.

[0017] In addition, the vehicle seat is provided with a lifting device operating member that operates the lifting device, and the upper end of the extension portion is positioned so as to overlap with the lifting device operating member in a side view, and is located rearward of the front end of the lifting device operating member and forward of the rear end of the lifting device operating member. According to the above configuration, it is possible to prevent the vehicle seat from becoming larger due to the leg rest portion, and it is also possible to prevent the seated occupant from feeling a foreign body sensation due to accidentally touching the extension portion. [Effects of the Invention]

[0018] According to the present invention, the ottoman and footrest can reduce the burden on the legs of the occupant, further improving comfort, and also making it possible to prevent the vehicle seat from becoming larger and heavier. Furthermore, it is possible to effectively prevent luggage placed on the seating surface of the seat cushion from falling off while the vehicle is moving.It is also possible to prevent the left and right extensions from interfering with the pivot shaft member while preventing the ottoman from becoming too large. It is also possible to improve the connection strength of the leg rest portion to the ottoman body. Furthermore, the strength of the leg rest support member in the front-rear direction can be improved, making it possible to stably support the leg rest.Furthermore, it is possible to prevent the occupant from feeling a foreign body sensation due to the occupant's legs coming into contact with the extension member. Furthermore, the occupant can place the soles of his / her feet on the leg rest portion with peace of mind, and it is possible to prevent the leg rest portion from interfering with the reclining motion of the seat cushion. Furthermore, the leg rest can be efficiently stored in the ottoman body, making it possible to make the ottoman compact. Furthermore, it is possible to improve the design of the vehicle seat. It is also possible to prevent a seated occupant from feeling a foreign body sensation when accidentally touching the extension portion. [Brief explanation of the drawings]

[0020] The configuration of a vehicle seat according to an embodiment of the present invention (the present embodiment) will be described below with reference to the drawings. However, the embodiment described below is an example for facilitating understanding of the present invention and is not intended to limit the present invention. In other words, the present invention may be modified or improved without departing from the spirit thereof, and of course, the present invention also includes equivalents thereof.

[0021] In the following, a vehicle seat S provided in a vehicle automobile such as a minivan will be taken as an example of a vehicle seat, and an example of the configuration thereof will be described. In the following description, the "seat front-rear direction" refers to the front-rear direction of the vehicle seat S, which is the direction that coincides with the traveling direction when the vehicle is traveling. The "seat width direction" refers to the width direction of the vehicle seat S, which is the direction that coincides with the left-right direction as seen by an occupant seated in the vehicle seat S. The "up-down direction" refers to the up-down direction of the vehicle seat S, which is the direction that coincides with the vertical direction when the vehicle is traveling on a horizontal plane. The outer and inner sides are defined based on the occupant. That is, the direction toward the center of the seat width direction is the inward direction, and the direction away from it is the outward direction. A common number is assigned to a pair of left and right components, and when specifying the left and right, the name indicating the component is appended with "left side" or "right side," and the letter "L" or "R" is added to the reference symbol.

[0022] As shown in Fig. 1, the vehicle seat S is a seat placed on the vehicle body floor and in which a vehicle occupant sits. In this embodiment, the vehicle seat S is a seat that is disposed on the right side (behind the driver's seat) of the rear seats corresponding to the rear seats of the vehicle. The vehicle seat S can also be used as a middle seat in the second row or a third seat in the third row in a vehicle that has three rows of seats in the longitudinal direction of the vehicle, or as a front seat corresponding to the front seats.

[0023] The vehicle seat S of this embodiment is configured to be able to transition between a plurality of states. Hereinafter, a state in which an occupant can sit in the vehicle seat S in an edge-sitting position (sitting with legs down) will be referred to as the "normal state" of the vehicle seat S (see FIG. 1). A state in which the seat back 2 is rotated rearward of the seat cushion 1 from the normal state will be referred to as the "reclining state" of the vehicle seat S (see FIG. 4). On the other hand, a state in which the position of the seat cushion 1 is higher than the position in the normal state (see FIGS. 2 and 5) will be referred to as the "height-raised state." A state in which the seat cushion 1 is moved to collapse (sink) onto the vehicle floor and the entire vehicle seat S is folded (see FIG. 6) will be referred to as the "folded state." Regardless of the state of the seat back 2, a state in which the seat cushion 1 is simply moved to collapse onto the vehicle floor will sometimes be referred to as the "collapsed state." The vehicle seat S can be arranged in a normal state, a reclined state, a height-raised state, and a folded state. The occupant can move the entire seat forward and backward by operating a slide rail operating lever 51 located on the front left side of the seat cushion 1. In addition, by operating a height frame operating lever 52 located on the front right side of the seat cushion 1, the occupant can rotate a front height link 22 and a rear height link 23 (described later) to change the height of the seat cushion 1. In addition, by operating a rotation lever 53 located on the shoulder of the seat back 2, the seat back 2 can be rotated forward or rearward and folded down. In addition, the shape, position, posture, etc. of each part of the vehicle seat S described below will be described assuming a normal state unless otherwise specified.

[0024] <Vehicle seat S> The overall configuration of a vehicle seat S according to this embodiment will be outlined with reference to Figs. 1 to 7. Fig. 1 is a perspective view of the vehicle seat S according to this embodiment, as seen obliquely from the front, and Fig. 2 is a perspective view showing the seat frame F of the vehicle seat S in a height-raised state. Fig. 3 is an explanatory diagram showing the seat frame F in a normal state, and Fig. 4 is an explanatory diagram showing the seat frame F in a reclined state. Fig. 5 is an explanatory diagram showing the seat frame F in a height-raised state, and Fig. 6 is a side view showing the seat frame F in a folded state. Fig. 7 is a perspective view of an ottoman, as seen obliquely from the front. In FIG. 1, for convenience of illustration, a part of the vehicle seat S is shown with the cover material Tr removed and the pad material P exposed.

[0025] 1, the vehicle seat S according to this embodiment mainly comprises a seat cushion 1, a seat back 2, a headrest 3, an ottoman 4, a reclining device 5, and a slide rail device 6. In the following description, the seat cushion 1, the seat back 2, the headrest 3, and the ottoman 4 may be collectively referred to as the seat body. 2, a seat frame F that forms the framework of the vehicle seat S is provided inside the vehicle seat S. The seat frame F includes a cushion frame 10, a back frame 30, a headrest frame 36, and an ottoman frame 40.

[0026] <Seat cushion 1> The seat cushion 1 is a support member that supports the buttocks of a seated occupant (hereinafter sometimes referred to as a seated person), and supports the seated person from below. As shown in FIG. 2, the seat cushion 1 has a cushion frame 10 that forms the skeleton of the seat cushion 1. The cushion frame 10 of this embodiment is composed of a cushion main body frame 11 that directly supports the seated person, and a height frame 20 that is disposed below the cushion main body frame 11 and supports the cushion main body frame 11 so that it can be raised and lowered. The cushion frame 10 corresponds to the seat cushion frame of the present invention.

[0027] <Cushion body frame 11> The cushion main body frame 11 is a frame body having a rectangular shape when viewed from above. The cushion main body frame 11 has cushion side frames 12 that constitute the frame body, a pan frame 13 that connects the cushion side frames 12, and a cushion frame member 14. The cushion main body frame 11 also has a dive down link 15 that connects to the height frame 20 at its front end.

[0028] The cushion side frame 12 is composed of a right cushion side frame 12R disposed on the right side of the cushion main body frame 11 and a left cushion side frame 12L disposed on the left side. The right cushion side frame 12R and the left cushion side frame 12L extend in the front-to-rear direction.

[0029] Each of the cushion side frames 12 has a folding mechanism. Specifically, each of the cushion side frames 12 has a rear cushion side frame 121 and a front cushion side frame 122 that are connected to be rotatable about a folding pivot shaft 123 (see FIGS. 3 and 4). By providing the folding mechanism to the left and right cushion side frames 12, the rear cushion side frame 121 rotates about the seatback connecting shaft 124 when the seatback 2 is tilted rearward. This allows the rear cushion side frame 121 to lift the folding pivot shaft 123 and the rear end of the front cushion side frame 122. Therefore, as shown in FIG. 4, the vehicle seat S can be transitioned to a fully flat state in which the seatback 2 and the seat cushion 1 are deployed approximately horizontally, thereby improving the convenience of the vehicle seat S.

[0030] The pan frame 13 is made of a plate-like member and connects the front ends of the left and right cushion side frames 12. The pan frame 13 has an ottoman pillar support portion (not shown) that connects to an ottoman pillar 44 (see FIG. 7) of the ottoman frame 40 (described later) to support the ottoman frame 40. The cushion frame member 14 is made of a pipe material and connects the rear sides of the cushion side frames 12. The cushion frame member 14 is partially bent, and the central portion in the seat width direction is curved rearward.

[0031] 2, a plurality of S-springs 17 are attached to the cushion main body frame 11 as pressure-receiving members that receive the load of the seated occupant, spanning the pan frame 13 and the cushion frame member 14. As described above, the central portion of the cushion frame member 14 has a shape that curves backward, so that the S-springs 17 can receive the load of the seated occupant over a wide area in the front-to-rear direction. In this embodiment, the pressure-receiving member is configured by a plurality of S-springs 17, but is not limited to this. The pressure-receiving member provided on the cushion main body frame 11 may be configured by an elastic plate-shaped member.

[0032] A slide rail operating lever 51 for operating the slide rail device 6 is provided at the front end of the left cushion side frame 12L. Also, a height frame operating lever 52 for raising and lowering the height frame 20 (described later) is provided at the front end of the right cushion side frame 12R.

[0033] The dive down link 15 is interposed between the cushion side frame 12 and the front end of the height frame 20, and supports the cushion main body frame 11 in cooperation with the back frame 30, which will be described later. The dive down links 15 are arranged on the right and left sides of the cushion frame 10, and the left and right dive down links 15 are connected by a dive down link member 16 extending in the seat width direction (see Figures 2 and 14).

[0034] The dive down link 15 is a long, plate-like member having a first rotation shaft 151 at one end in the longitudinal direction and a second rotation shaft 152 at the other end. The first rotation shaft 151 is rotatably connected to the cushion side frame 12, and the second rotation shaft 152 is rotatably connected to the height side frame 21 (see Figures 5 and 6). By rotating the dive down link 15, the vehicle seat S transitions between a normal state in which the cushion main body frame 11 is spaced above the height frame 20, and a reclined state (or folded state) in which the cushion main body frame 11 is sunk downward.

[0035] The dive down link member 16 connects the left and right dive down links 15 and increases the rigidity of the dive down links 15. In addition, by connecting the left and right dive down links 15 with the dive down link member 16, it becomes possible to smoothly raise and lower the cushion main body frame 11 relative to the height frame 20.

[0036] <Height frame 20> The cushion frame 10 includes a height frame 20 below the cushion body frame 11 that supports the cushion body frame 11. The height frame 20 is a frame body having a rectangular shape when viewed from above. The height frame 20 also has a front height link 22 and a rear height link 23 interposed between the height side frame 21 and the slide rail device 6.

[0037] The height side frame 21 is composed of a right height side frame 21R arranged on the right side of the height frame 20 and a left height side frame 21L arranged on the left side. The right height side frame 21R and the left height side frame 21L have elongated shapes and extend in the front-to-rear direction. The right height side frame 21R and the left height side frame 21L are plate-like bodies with a generally triangular shape that extends upward and rearward. 2, the left height side frame 21L is bent in the seat width direction. This allows the left height side frame 21L to be positioned above the slide rail device 6 while avoiding interference with the slide rail locking device 63 disposed on the slide rail device 6.

[0038] The front height link 22 and the rear height link 23 are elongated plate-like members that can raise and lower the seat cushion 1. The front height link 22 is rotatably connected to the height side frame 21 via a first pivot shaft 221 and to the slide rail device 6 via a second pivot shaft 222 provided on the front connecting bracket 54. The front height link 22 is a driven link mechanism that operates in response to the rear height link 23 when the height frame operating lever 52 is operated. The front height link 22 and the rear height link 23 correspond to the lifting device of the present invention, and the height frame operating lever 52 corresponds to the lifting device operating member of the present invention.

[0039] The rear height link 23 is rotatably connected to the height side frame 21 via a first pivot shaft 231 and to the slide rail device 6 via a second pivot shaft 232 provided on the rear connecting bracket 55. The rear height link 23 is a driven link mechanism that is driven when the height frame operating lever 52 is operated.

[0040] The front height links 22 and the rear height links 23 rotate so as to stand up relative to the slide rail device 6, thereby raising the height frame 20. As a result, the vehicle seat S transitions from the normal state shown in FIG. 3 to the height-raised state shown in FIG. 5. Meanwhile, the front height links 22 and the rear height links 23 rotate so as to lean backward relative to the slide rail device 6, thereby lowering the height frame 20. As a result, the vehicle seat S transitions from the height-raised state shown in FIG. 5 to the normal state shown in FIG. 3. In the following description, the state in which the height frame 20 is lowered is referred to as the height-lowered state.

[0041] The second rotation shaft 152 of the dive down link 15 is rotatably provided at the front end of the left and right height side frames 21. In addition, the rear end of each height side frame 21 is connected to the side connecting frame 32 of the back frame 30 via the reclining device 5. This allows the left and right height side frames 21 to support the cushion main body frame 11 from below via the dive down link 15 and the side connecting frame 32.

[0042] <Pad material P and cover material Tr> A pad material P for the seat cushion is placed on the cushion main body frame 11, and the pad material P is covered with a skin material Tr. The pad material P is a cushion material and is made of, for example, a urethane resin (foam resin) such as soft polyurethane foam. The pad material P may be made of biomass urethane. The skin material Tr that covers the pad material P is made of, for example, a stretchable synthetic leather material. The skin material Tr may be made of cloth, film, leather, etc.

[0043] <Seatback 2> The seat back 2 is a support member that supports the back of a seated occupant, and supports the seated occupant from behind. As shown in Fig. 2, the seat back 2 has a back frame 30 that forms the skeleton of the seat back 2. The seat back 2 has a pad material P for the seat back 2 that covers the back frame 30, and a cover material Tr that covers the pad material P.

[0044] The back frame 30 is a frame body having a substantially rectangular shape when viewed from the front. The back frame 30 mainly comprises a pair of back side frames 31, a side connecting frame 32, a back upper frame 33, a back lower frame 34, and a pressure plate 35. The pair of back side frames 31 are elongated frame members extending in the vertical direction and are disposed apart from each other while facing each other in the seat width direction. The side connecting frame 32 is connected to the lower end of the back side frame 31 and the reclining device 5. In addition, the side connecting frame 32 is connected to the upper end (rear end) of the rear cushion side frame 121.

[0045] The back upper frame 33 connects the upper ends of the left and right back side frames 31, and has attached thereto a headrest frame 36 and a rotation lever 53. The rotation lever 53 is operated when the seat back 2 is rotated forward or backward relative to the seat cushion 1. The back lower frame 34 connects the lower ends of the left and right back side frames 31 together. The pressure plate 35 is a plate-shaped member that is attached to the inside of the back frame 30 and receives the weight of a seated occupant. The back frame 30 corresponds to the seat back frame of the present invention.

[0046] <Headrest 3> The headrest 3 is a support member that supports the head of a seated occupant from behind. As shown in Fig. 2, the headrest 3 has a headrest frame 36 that forms the skeleton of the headrest 3. The headrest 3 has a padding material P for the headrest 3 that covers the headrest frame 36, and a skin material Tr that covers the padding material P.

[0047] <Ottoman 4> The ottoman 4 is a support member for supporting the legs of a seated person, and includes an ottoman body 4a that supports the calves of the seated person from behind or below, and leg rest pipes 45 on which the soles of the seated person's feet can be placed (see FIG. 7). The ottoman body 4a has a base end 4a1 that connects to the seat cushion 1 and a tip end 4a2 located on the opposite side of the base end 4a1. The leg rest pipe 45 has left and right extensions 451 and sole contact portions 452 that connect tip portions 4512 of the left and right extensions 451 and can contact the soles of the occupant's feet. An opening OP is formed between the tip portion 4a2 of the ottoman main body 4a and the sole contact portion 452. An occupant seated in the vehicle seat S can place the arch of their foot on the sole contact portion 452 by inserting their heel from the front to the rear of the opening OP. This allows the legs to be placed stably, reducing the burden on the occupant's legs and improving comfort. The sole contact portion 452 is also made of a hollow round pipe material. This makes it possible to prevent the ottoman 4 and the vehicle seat S from becoming larger and heavier. The ottoman frame 40, which forms the framework of the ottoman 4, will be described in detail below.

[0048] <Reclining device 5> The reclining device 5 rotatably connects the seat back 2 to the seat cushion 1. More specifically, as shown in FIGS. 3, 4, and 6, the reclining device 5 rotatably connects the rear end of the height frame 20 and the lower end of the back frame 30 that constitute the cushion frame 10. The reclining device 5 rotates the seat back 2 rearward relative to the seat cushion 1, thereby transitioning the vehicle seat S from the normal state shown in FIG. 3 to the reclined state shown in FIG. 4. The reclining device 5 also rotates the seat back 2 forward relative to the seat cushion 1, thereby transitioning the vehicle seat S from the normal state shown in FIG. 3 to the folded state shown in FIG. 6.

[0049] <Slide rail device 6> As shown in FIGS. 1 and 2, the slide rail device 6 connects the vehicle seat S to the vehicle floor so that the seat S can slide in the front-rear direction. As shown in FIG. 1, the slide rail device 6 is provided below the vehicle seat S. The slide rail device 6 has a known structure (the structure of a general slide rail mechanism). In detail, the slide rail device 6 has a lower rail 61 fixed to the vehicle floor and an upper rail 62 that is slidable in the front-rear direction relative to the lower rail 61. The slide rail device 6 also has a slide rail locking device 63 that restricts the sliding movement of the upper rail 62 relative to the lower rail 61. The slide rail locking device 63 can release the restriction on the sliding movement by operating a slide rail operating lever 51 provided on the seat cushion 1.

[0050] <Details of Ottoman Frame 40> Next, the ottoman frame 40 will be described in detail with reference to FIGS. 8 shows a perspective view of the ottoman frame 40 seen diagonally from the front. As shown in FIG. 8, the ottoman frame 40 has left and right ottoman side frames 41, an ottoman rotation shaft 42, a connecting pipe 43, left and right ottoman pillars 44, and a leg rest pipe 45.

[0051] The left and right ottoman side frames 41 face each other at positions spaced apart from each other in the seat width direction. Each of the left and right ottoman side frames 41 has a box shape and includes an outer plate portion 411, an inner plate portion 412, a front plate portion 413, and a rear plate portion 414 (see FIG. 13). For ease of explanation, the front plate portion 413 is not shown in FIGS. 7 to 11. The outer plate portion 411 and the inner plate portion 412 face each other in the seat width direction, and a space in which an extension portion 451 (described later) can slide is formed between the outer plate portion 411 and the inner plate portion 412. In addition, a connecting bracket 415 that slidably supports the extension portion 451 is fixed to the lower end of the inner plate portion 412 by welding (see FIG. 10).

[0052] The connecting bracket 415 has a generally U-shape in side view, and includes a support wall 4151 that supports the extension 451, and a front wall 4152 and a rear wall 4153 located at both ends of the support wall 4151 in the front-to-rear direction. This improves the strength of the connecting bracket 415, making it possible to stably support the leg rest pipe 45. The connecting bracket 415 corresponds to a leg rest support member of the present invention. 13, a plurality of reinforcing ribs 4151a extending in the front-rear direction may be formed on the support wall 4151. The reinforcing ribs 4151a are concave-convex grooves provided on the support wall 4151 made of a plate-like member. This can further improve the strength of the connecting bracket 415 and can also improve the connection strength of the leg rest pipe 45 to the ottoman main body 4a.

[0053] A restricting member 416 is provided below the support wall portion 4151 of the connecting bracket 415. The restricting member 416 can restrict the position of the leg support pipe 45 relative to the connecting bracket 415. The restricting member 416 will be described in detail later. The restricting member 416 corresponds to the position restricting member of the present invention.

[0054] The ottoman rotation shaft 42 is located at the base end 41a of the ottoman main body 4a, extends in the seat width direction, and rotatably connects the ottoman main body 4a to the seat cushion 1 (see FIG. 3). More specifically, the ottoman rotation shaft 42 rotatably connects the left and right ottoman side frames 41 to the cushion frame 10. The occupant can rotate the ottoman main body 4a around the ottoman rotation shaft 42 by operating the ottoman rotation strap 46. The ottoman rotation shaft 42 corresponds to the rotation shaft member of the present invention.

[0055] The connecting pipe 43 is located at the tip 41b of the ottoman main body 4a, extends in the seat width direction, and connects the left and right ottoman side frames 41. By connecting the left and right ottoman side frames 41, the connecting pipe 43 improves the strength of the ottoman 4.

[0056] The ottoman pillar 44 connects the ottoman 4 to the cushion frame 10 so that it can slide in the front-to-rear direction. The ottoman pillar 44 is a round pipe material, one end of which is slidably connected to an ottoman support portion (not shown) formed on the cushion frame 10, and the other end of which is welded and fixed to the inner plate portion 412 of the ottoman side frame 41. In addition, an engagement groove 441 is formed on the outer periphery of the ottoman pillar 44 to regulate the position of the ottoman pillar 44 in the front-rear direction.

[0057] The leg rest pipe 45 is a round pipe material on which the plantar arches (arches) of an occupant seated in the vehicle seat S can be placed. The leg rest pipe 45 has left and right extensions 451 and sole contact parts 452 that extend in the seat width direction and connect tip parts 4512 of the extensions 451, and has a roughly U-shape. The extension 451 passes through a through-hole formed in the support wall 4151 of the connecting bracket 415. The extension 451 also has a circular flange 4514 at the end opposite the sole contact portion 452 (the upper end in FIG. 10). The circular flange 4514 abuts against the support wall 4151 of the connecting bracket 415. This allows the leg rest pipe 45 to be stably connected to the ottoman main body 4a.

[0058] 8 and 9, the movement of the leg rest pipe 45 will be described. The leg rest pipe 45 slides inside the space formed between the outer plate portion 411 and the inner plate portion 412 of the box-shaped ottoman side frame 41. This allows the leg rest pipe 45 to move between an extended position (see FIG. 8) in which it protrudes toward the tip of the ottoman main body 4a, and a retracted position (see FIG. 9) in which it is retracted into the ottoman main body 4a.

[0059] Fig. 11 is a front view of the ottoman frame 40 when the leg rest pipe 45 is in the stored position, and Fig. 12 is a cross-sectional view taken along the line XII-XII of Fig. 11. As shown in Fig. 12, when the tip end 4a2 of the ottoman main body 4a, which is rotatable via the ottoman rotation shaft 42, is in a downward position facing downward, the extension 451 is located forward of the ottoman rotation shaft 42. More specifically, the base end 4511 (the upper end in Fig. 12) of the extension 451 is located forward of the front end of the ottoman rotation shaft 42, which extends in the seat width direction. This prevents interference between the extension 451 and the ottoman rotation shaft 42 when the leg rest pipe 45 is displaced between the stored position and the deployed position.

[0060] As described above, the restricting member 416 can restrict the leg rest pipe 45 to a predetermined position between the deployed position and the retracted position. More specifically, the restricting member 416 has a through hole and a locking member 4161 that is provided at the periphery of the through hole and engages with a locking portion 4513 provided on the outer periphery of the extension portion 451. The locking member 4161 is biased in a direction in which it engages with the locking portion 4513. Engagement of the locking member 4161 and the locking portion 4513 with each other makes it possible to restrict the leg rest pipe 45 to a predetermined position between the deployed position and the retracted position. As will be described later, when the lower end of the leg rest pipe 45 abuts against the vehicle floor, the restriction by the restricting member 416 is released, and the leg rest pipe 45 can be displaced toward the retracted position.

[0061] Next, the state in which the above-mentioned ottoman 4 is attached to the seat cushion 1 will be described with reference to Figures 14 and 15. Figure 14 shows a side view of the seat frame F in the folded state, and Figure 15 shows a top view of the seat frame F. As shown in FIG. 14 , the ottoman 4 is attached to the seat cushion 1 so that the ottoman pillar 44 is supported by the cushion frame 10 and is slidable in the front-rear direction. When the ottoman 4 slides rearward, the rear end of the ottoman pillar 44 is located between the front height link member 24, which connects the left and right front height links 22, and the dive down link member 16, which connects the left and right dive down links 15. More specifically, the rear end of the ottoman pillar 44 is located forward of the front end position (P1 in FIG. 14 ) of the front height link member 24 and rearward of the rear end position (P2 in FIG. 14 ) of the dive down link member 16. This allows the ottoman pillar 44 to slide in the front-rear direction relative to the cushion frame 10, while preventing the ottoman pillar 44 from coming into contact with and interfering with the front height link member 24.

[0062] Additionally, the upper end of the extension 451 is located between the top surface of the pan frame 13 and the top end of the ottoman main body 4a in the vertical direction. More specifically, the upper end of the extension 451 is located above the top surface of the pan frame 13 (L1 in FIG. 14) and below the top end of the ottoman main body 4a (L2 in FIG. 14). This allows the leg rest pipe 45 to slide between the stored position and the deployed position, and can be efficiently stored in the stored position. This allows the ottoman 4 to be made compact.

[0063] Furthermore, when the vehicle seat S is in a height-lowered state, the leg rest pipes 45 are disposed above the slide rail device 6 (see FIGS. 3 and 4). Therefore, in height-lowered states including the normal state, the soles of the occupant's feet can be placed on the leg rest pipes 45, which reduces the burden on the occupant's legs and improves comfort.

[0064] Furthermore, when the vehicle seat S is in the folded state, the lower end of the leg rest pipe 45 may come into contact with the vehicle floor. At this time, the engagement between the locked portion 4513 provided on the extension portion 451 and the locking member 4161 provided on the restricting member 416 is released. Therefore, it is possible to prevent the leg rest pipe 45 from interfering with the reclining movement of the seat cushion 1.

[0065] 15, the extension 451 located on the right side in the seat width direction faces the height frame operation lever 52 in the seat width direction. In other words, the base end 4511 located at the upper end of the right extension 451 is disposed in a position overlapping with the height frame operation lever 52 in a side view. Explaining in more detail, the base end 4511 is located behind the front end of the height frame operation lever 52 and forward of the rear end of the height frame operation lever 52. Similarly, the extension 451 located on the left side in the seat width direction faces the slide rail operation lever 51 in the seat width direction. In other words, the base end 4511 located at the upper end of the left extension 451 is disposed in a position overlapping with the slide rail operation lever 51 in a side view. Explaining in more detail, the base end 4511 is located rearward of the front end of the slide rail operation lever 51 and forward of the rear end of the slide rail operation lever 51. This makes it possible to prevent the leg rest pipe 45 having left and right extensions 451 from increasing in size of the vehicle seat S, and also makes it possible to prevent the occupant from feeling a foreign body sensation when accidentally touching the extension 451.

[0066] As described above, the ottoman 4 has the ottoman main body 4a and the leg rest pipe 45 on which the soles of the occupant's feet can be placed, and an opening OP is formed between the tip 4a2 of the ottoman main body 4a and the leg rest pipe 45. Therefore, an occupant seated in the vehicle seat S can place the arch of their foot on the leg rest pipe 45 by inserting their heel from the front to the rear of the opening OP, thereby improving the comfort of the occupant. In addition, because the leg rest pipe 45 is made of a round pipe material, it is possible to prevent the vehicle seat S from becoming larger and heavier.

[0067] <Method for manufacturing vehicle seat S> Next, a method for manufacturing the vehicle seat S will be described. First, the ottoman frame 40 is assembled. Specifically, the left and right ottoman side frames 41, the ottoman rotation shaft 42, the connecting pipe 43, the ottoman pillar 44, and the leg rest pipe 45 are connected together to assemble the ottoman frame 40. Here, the leg rest pipe 45 is assembled to the left and right ottoman side frames 41 via the connecting brackets 415 and the restricting members 416. Next, the padding material P is placed on the ottoman frame 40 and covered with the covering material Tr, thereby completing the assembly of the ottoman 4. At this time, an opening OP is formed between the tip end 4a2 of the ottoman body 4a and the leg rest pipe 45 located in the deployed position.

[0068] Similarly, the cushion frame 10, the back frame 30, and the headrest frame 36 that constitute the seat frame F are assembled. Next, a pad material P is placed on the cushion frame 10 and the back frame 30, and is covered with a covering material Tr, thereby completing the assembly of the seat cushion 1 and the seat back 2. After the headrest frame 36 is covered with the skin material Tr, the pad material P is injected inside the skin material Tr and then foamed, thereby completing the assembly of the headrest 3.

[0069] Next, the ottoman 4 is connected to the seat cushion 1 via the ottoman pillar 44, the seat back 2 is connected to the headrest 3, and finally the seat back 2 is connected to the seat cushion 1, thereby assembling the seat body. The seat body is installed on the vehicle floor by assembling the cushion frame 10 to the slide rail device 6 via the front height link 22 and the rear height link 23. In this way, the manufacturing of the vehicle seat S is completed.

[0070] Although a vehicle seat S according to one embodiment of the present invention has been described above, the above-described embodiment is merely an example for facilitating understanding of the present invention and is not intended to limit the present invention. In other words, the present invention may be modified or improved without departing from the spirit thereof, and the present invention naturally includes equivalents thereof.

[0071] <First Modification> In the above-described embodiment, the ottoman body 4a is covered with the covering material Tr, while the leg rest pipe 45 is exposed to the outside of the covering material Tr, but this is not limiting. The leg rest pipe 45 may be covered. 16 and 17 are side views of an ottoman 4A according to a first modified example. As shown in Fig. 16 and 17, the ottoman 4A has an ottoman main body 4Aa and a leg rest pipe 45. A tip portion 4Aa2 of the ottoman main body 4Aa is covered with a tip covering material 4Ad having an opening / closing member 4Ac.

[0072] The opening / closing member 4Ac can be in a covering state (see FIG. 16) in which it covers the ottoman main body 4Aa and the leg rest pipe 45 in the stored position, and an open state (see FIG. 17) in which it exposes the leg rest pipe 45 in the deployed position. The opening / closing member 4Ac is a hook-and-loop fastener, but is not limited to this. The opening / closing member 4Ac may also be a permanent magnet as long as it can cover the leg rest pipe 45 in the stored position. By providing a tip cover material 4Ad having the opening / closing member 4Ac at the tip portion 4Aa2 of the ottoman main body 4Aa, it is possible to improve the design of the vehicle seat S.

[0073] <Second Modification> In the above embodiment, the leg rest pipe 45 has a substantially U-shape, which forms an opening OP between the tip 4a2 of the ottoman main body 4a and the leg rest pipe 45, but this is not limiting. It is sufficient that an opening OP is formed between the ottoman main body 4a and the leg rest pipe 45 through which the occupant's heel can be inserted. Fig. 18 is a side view of an ottoman 4B according to a second modification. As shown in Fig. 18, the ottoman 4B has an ottoman main body 4Ba and a footrest portion 45B on which the soles of the occupant's feet can be placed. The footrest portion 45B is a support member that supports the soles of the occupant's feet.

[0074] Slits 4Ba3 are formed at both ends of the ottoman main body 4Ba in the seat width direction, extending distally from the base end 4Ba1 to the distal end 4Ba2. The slits 4Ba3 can guide the sliding of the leg rest 4Bb. The ottoman main body 4Ba also has a through-hole 4Ba4 formed in the center in the seat width direction. Therefore, when the leg rest 45B slides distally along the slits 4Ba3, an opening OP is formed between the ottoman main body 4Ba and the leg rest 45B. As a result, the ottoman 4B according to the second modified example can reduce the burden on the occupant's legs and improve comfort, similar to the above-described embodiment.

[0075] <Third Modification> In the above embodiment, the opening OP is formed between the ottoman main body 4a and the leg rest pipe 45 when the leg rest pipe 45 is displaced toward the tip of the ottoman main body 4a, but this is not limiting. The opening OP may also be formed between the ottoman main body 4a and the leg rest pipe 45 by the leg rest pipe 45 rotating forward. Fig. 19 is a side view of an ottoman 4C according to a third modified example. As shown in Fig. 19, the ottoman 4C according to the third modified example has an ottoman main body 4Ca and a leg rest 45C on which the legs of a passenger can be placed. The leg rest 45C is a support member that supports the soles of the feet of the passenger.

[0076] The leg rest portion 45C has left and right extensions 451C, an unfolding portion 453C, and a rotating hinge 454C. The left and right extensions 451C are connected to a distal end portion 4Ca2 of the ottoman main body 4Ca and extend distally from the base end portion 4Ca1 of the ottoman main body 4Ca toward the distal end portion 4Ca2. The unfolding portion 453C is rotatably connected to the extensions 451C via the rotating hinge 454C. Therefore, as shown in FIG. 19 , by rotating the unfolding portion 453C around the rotating hinge 454C and unfolding it horizontally, the soles of the occupant's feet can be placed against the unfolding portion 453C. Furthermore, a through-hole 4515C penetrating the extension 451C is formed in the extension 451C. Therefore, when the unfolding portion 453C is rotated, an opening OP is formed between the tip end 4Ca2 of the ottoman main body 4Ca and the unfolding portion 453C. This allows the ottoman 4C according to the third modified example to achieve the same effects as those of the above-described embodiment.

[0077] <Fourth Modification> Fig. 20 is a side view of an ottoman 4D according to a fourth modified example. As shown in Fig. 20, the ottoman 4D according to the fourth modified example has an ottoman main body 4Da and a leg rest 45D on which the legs of an occupant can be placed. The leg rest 45D is a support member that supports the soles of the feet of the occupant.

[0078] The leg rest 45D has left and right extensions 451D, an unfolding portion 453D, and a rotating hinge 454D. The extension 451D is connected to a distal end 4Da2 of the ottoman main body 4Da and is slidably connected to the distal end 4Da2 from the base end 4Da1 of the ottoman main body 4Da to the distal end 4Da2. The unfolding portion 453D is rotatably connected to the extension 451D via the rotating hinge 454D. Therefore, as shown in FIG. 20 , with the extension 451D sliding toward the distal end of the ottoman main body 4Da, the unfolding portion 453D can be rotated around the rotating hinge 454D to unfold horizontally, allowing the soles of the occupant's feet to come into contact with the unfolding portion 453D and be placed thereon. Furthermore, when the unfolding portion 453D is unfolded horizontally, an opening OP is formed between the tip end 4Da2 of the ottoman main body 4Da and the unfolding portion 453D, which allows the ottoman 4D according to the fourth modified example to achieve the same effects as those of the above-described embodiment.

[0079] In the above-described embodiment, a vehicle seat S mounted on a vehicle is given as an example of a vehicle seat, and an example of the configuration thereof has been described. However, the present invention is not limited to seats mounted on ground vehicles having wheels such as automobiles and trains, and may also be applied to seats mounted on aircraft, ships, and other vehicles that move on non-ground surfaces, for example.
