Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above prior art, the deployment directions of the first support body and the second support body are opposite to each other, and a gap occurs between the first support body and the second support body when they are deployed. Therefore, the supportability for the occupant's calves is poor.

[0005] An object of the present invention is to obtain an ottoman and a vehicle seat with good supportability for the occupant's calves.

Means for Solving the Problems

[0006] The ottoman of the first embodiment includes a first flap portion that is rotatably connected to the front end of the seat cushion of a vehicle seat about a first axis along the left-right direction of the seat and can take on a retracted state in which it extends downward from the front end of the seat cushion and an extended state in which it extends forward from the front end of the seat cushion and a second flap portion that is positioned on the opposite side of the front end of the seat cushion from the first flap portion and is rotatably connected to the first flap portion about a second axis along the left-right direction of the seat, and has an extension portion that extends radially outward from the second axis from the connecting portion, and can take on a retracted state in which it overlaps the back surface of the first flap portion and an extended state in which the extension portion extends forward from the seat side of the first flap portion in the extended state.

[0007] In the first embodiment of the ottoman, the first flap portion is rotatably connected to the front end of the seat cushion of the vehicle seat about a first axis along the left-right direction of the seat. This first flap portion can be in a retracted state, extending downward from the front end of the seat cushion, and in an extended state, extending forward from the front end of the seat cushion. The second flap portion is positioned on the opposite side of the front end of the seat cushion from the first flap portion. This second flap portion has a connecting portion that is rotatably connected to the first flap portion about a second axis along the left-right direction of the seat, and an extension portion that extends radially outward from the connecting portion along the second axis. This second flap portion can be in a retracted state, with the extension portion overlapping the back surface of the first flap portion, and in an extended state, with the extension portion extending forward from the first flap portion in the extended state towards the seat.

[0008] When the first and second flaps are deployed, the second flap extends outwards from the front of the seat relative to the first flap, providing sufficient length to stably support the occupant's knees and calves. Furthermore, since no gap is created between the first and second flaps when deployed, the support for the occupant's calves is improved.

[0009] In the second embodiment of the ottoman, the second flap portion may be in a luggage stopper state in which the extension portion extends upward toward the seat side of the first flap portion when it is extended.

[0010] In the ottoman of the second embodiment, when the second flap is in the luggage stopper state when the first flap is extended, the extension of the second flap extends upward toward the seat side of the first flap. This allows the extension of the second flap to be used as a stopper for luggage placed on the seat cushion.

[0011] The ottoman of the third embodiment, in the first or second embodiment, includes a first flap portion comprising a first frame, one end of which is rotatably supported with respect to a first axis and the other end of which is fixed to a second axis, and a first lock provided at one end of the first frame, which restricts the rotation of the first frame with respect to the first axis and releases the restriction when a first operating portion is operated.

[0012] In the third embodiment of the ottoman, one end of the first frame of the first flap portion is pivotally supported on a first axis, and the second axis is fixed to the other end of the first frame. A first lock is provided on one end of the first frame. This first lock restricts the rotation of the first frame relative to the first axis. This prevents unintended rotation of the first flap portion relative to the first axis. Furthermore, this first lock is released when the first operating part is operated, so that rotation of the first flap portion relative to the first axis is permitted.

[0013] The ottoman of the fourth embodiment, in any one of the first to third embodiments, has a second flap portion comprising a second frame, one end of which is pivotally supported on the second axis, and a second lock provided on one end of the second frame, which restricts the rotation of the second frame on the second axis and releases the restriction when a second operating portion is operated.

[0014] In the ottoman of the fourth embodiment, one end of the second frame of the second flap portion is pivotally supported on a second axis. A second lock is provided on one end of the second frame. This second lock restricts the rotation of the second frame on the second axis. This prevents unintended rotation of the second flap portion on the second axis. Furthermore, this second lock is released when the second operating part is operated, allowing rotation of the second flap portion on the second axis.

[0015] A fifth embodiment of a vehicle seat comprises a seat cushion on which a vehicle occupant sits, a seat back that supports the occupant's back, and an ottoman in any one of the first to fourth embodiments, the first flap portion of which is connected to the front end of the seat cushion via the first axis.

[0016] In the fifth embodiment of the vehicle seat, the back of the occupant seated on the seat cushion is supported by the seat back. The front end of the seat cushion is connected to the first flap portion of an ottoman via a first axis. Since this ottoman is of any one of the first to fourth embodiments, the aforementioned effects are obtained. [Effects of the Invention]

[0017] As described above, the ottoman and vehicle seat according to the present invention provide excellent support for the occupant's calves. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0019] It seems there is an incorrect tag in ID=38. It should be instead of <00001韶光易逝,容颜易老,唯有才华,能伴你一生。4>. Please check and correct if necessary.Hereinafter, a vehicle seat 10 according to one embodiment of the present invention will be described with reference to Figures 1 to 15. In each figure, some reference numerals may be omitted for the sake of clarity. The arrows FR, LH, RH, and UP indicated as appropriate in each figure indicate the front, left, right, and top of the vehicle seat 10, respectively. Hereafter, when simply referring to the front, back, left, right, up, and down directions, these directions will be in relation to the vehicle seat 10.

[0020] As shown in Figure 1, the vehicle seat 10 according to this embodiment comprises a seat cushion 12 on which the vehicle occupant sits, a seat back 14 that supports the occupant's back, a headrest 16 that supports the occupant's head, and an ottoman 20 that supports the occupant's lower legs. A recess 12A for accommodating the ottoman 20 is formed at the front end of the seat cushion 12. The seat cushion 12 is connected to the floor of the vehicle (not shown) via a well-known seat slide mechanism 18 and a lifter mechanism 19 (see Figure 9). The front-rear, left-right, up-down directions of this vehicle seat 10 coincide with the front-rear, left-right, up-down directions of the vehicle.

[0021] As shown in Figures 1 to 8, the ottoman 20 includes a first flap portion 22 and a second flap portion 24. The first flap portion 22 is rotatably connected to the front end of the seat cushion 12 around a first axis 26 (see Figures 9 and 10) that is aligned in the left-right direction. The first flap portion 22 is configured to be able to take on two states: a retracted state extending downward from the front end of the seat cushion 12 (see Figures 1 and 5) and an extended state extending forward from the front end of the seat cushion 12 (see Figures 2 to 4 and 6 to 8).

[0022] The second flap section 24 is positioned on the opposite side of the front end of the seat cushion 12 from the first flap section 22. This second flap section 24 has a connecting section 24A that is rotatably connected to the first flap section 22 around a second axis 28 (see Figures 9 and 10) that runs in the left-right direction, and an extension section 24B that extends radially outward from the connecting section 24A along the second axis 28. This second flap section 24 is configured to be in a stowed state where the extension section 24B overlaps the back surface of the first flap section 22 (see Figures 1, 2, 5 and 6), an extended state where the extension section 24B extends forward of the extended first flap section 22 (see Figures 3 and 7), and a luggage stopper state where the extension section 24B extends upward of the extended first flap section 22 (see Figures 4 and 8). Details will be explained below.

[0023] As shown in Figure 9, the cushion frame 30 that constitutes the framework of the seat cushion 12 has a pair of left and right side frames 32 that extend in the front-rear direction on the left and right sides of the seat cushion 12. Each side frame 32 is formed in an elongated shape from, for example, a press-formed metal plate, and is arranged with the front-rear direction as the longitudinal direction and the left-right direction as the thickness direction. The front ends of the left and right side frames 32 are connected in the left-right direction by a first axis 26.

[0024] The first shaft 26 is made of, for example, a metal pipe and is oriented with its axis running in the left-right direction. Both ends of the first shaft 26 in the left-right direction are inserted into circular through holes (not shown) formed in the front ends of the left and right side frames 32, and are fixed to the left and right side frames 32 by means of welding or other means. This first shaft 26 is a component of the ottoman 20, but also serves as part of the cushion frame 30.

[0025] As shown in Figures 9 to 12, the first flap section 22 includes a first frame 34, one end of which is rotatably supported on a first shaft 26 and the other end of which a second shaft 28 is fixed, and a first lock 42 provided at one end of the first frame 34, which restricts the rotation of the first frame 34 on the first shaft 26 and releases the restriction when the strap 50, which is a first operating member, is operated.

[0026] The first frame 34 is composed of a pair of left and right first frame members 36. The left and right first frame members 36 are formed in an elongated shape from, for example, press-formed metal plates. The left and right first frame members 36 are arranged spaced apart from each other in the left-right direction, with the radial direction of the first shaft 26 as the longitudinal direction. The first shaft 26 is inserted through circular through holes (not shown) formed at one end of the left and right first frame members 36 in the longitudinal direction. As a result, the left and right first frame members 36 are supported so as to be rotatable around the first shaft 26.

[0027] First pads 38 (see Figures 1 to 8) are attached to the left and right first frame members 36, and the first pads 38 are covered by a first skin 40 (see Figures 1 to 8). The first pads 38 are made of a foam material such as urethane foam, and the first skin 40 is made of multiple skin pieces made of, for example, cloth, leather, or synthetic leather, which are sewn together to form a bag.

[0028] The first lock 42 comprises a first ratchet member 44 fixed to the first shaft 26 at one longitudinal end of one (in this case, the right) first frame member 36 and having ratchet teeth 44A formed thereon; a first lock member 46 displaceably (in this case rotatably) attached to one longitudinal end of one first frame member 36; a tension coil spring 48 as a first biasing member that biases the first lock member 46 in the direction of engagement with the ratchet teeth 44A of the first ratchet member 44; and a strap 50 attached to the first lock member 46.

[0029] The first ratchet member 44 is positioned to the left of one of the longitudinal ends of the first frame member 36. This first ratchet member 44 is formed in a substantially disc shape from, for example, a metal plate, and is positioned with the left-right direction as its axis. Ratchet teeth 44A are formed on a part of the outer circumference of the first ratchet member 44. A circular through-hole (not shown) is formed in the center of the first ratchet member 44 through which the first shaft 26 is inserted. This first ratchet member 44 is fixed to the first shaft 26 by means of welding or other means. An E-ring 52 is positioned to the right of one of the longitudinal ends of the first frame member 36. By attaching this E-ring 52 to the first shaft 26, the axial displacement of one of the first frame members 36 relative to the first shaft 26 is restricted.

[0030] The first locking member 46 is composed of a lever member 54 positioned to the right of one of the longitudinal ends of the first frame member 36, a locking plate 56 positioned to the left of one of the longitudinal ends of the first frame member 36, and a connecting shaft 58 that penetrates the rear end of one of the longitudinal ends of the first frame member 36 in the left-right direction.

[0031] The lever member 54 and the locking plate 56 are made of, for example, a press-formed metal plate. The lever member 54 is formed in a roughly L-shape when viewed from the left to right. One end of the connecting shaft 58 is fixed to the middle part of the lever member 54 by means of crimping or the like. The locking plate 56 is formed in a roughly L-shape when viewed from the left to right. The other end of the connecting shaft 58 is fixed to one end of the locking plate 56 by means of crimping or the like. As a result, the lever member 54 and the locking plate 56 are connected via the connecting shaft 58, and the lever member 54 and the locking plate 56 are configured to rotate integrally around the connecting shaft 58 relative to the first frame member 36.

[0032] One end of the strap 50 is locked to one end of the lever member 54. The other end of the strap 50 extends outward from the first flap portion 22, as shown in Figures 1 to 3 and Figures 5 to 8. One end of the tension coil spring 48 is locked to the other end of the lever member 54. The other end of the tension coil spring 48 is locked to one end of the first lever member 54 in the longitudinal direction. A claw portion 56A is formed at the other end of the lock plate 56, protruding toward the first ratchet member 44.

[0033] The locking plate 56 and the lever member 54 are biased by a tension coil spring 48 in the engagement direction, such that the claw portion 56A of the locking plate 56 engages (meets) with the ratchet teeth 44A of the first ratchet member 44. This engagement restricts the rotation of the first flap portion 22 relative to the first shaft 26. When the strap 50 is pulled against the biasing force of the tension coil spring 48, the locking plate 56 and the lever member 54 are rotated in the opposite direction to the engagement direction, and the engagement (i.e., the rotation restriction) is released.

[0034] As described above, a second shaft 28 is fixed to the other longitudinal ends of the left and right first frame members 36 of the first flap portion 22 having the above configuration. The second shaft 28 is made of, for example, a metal pipe and is positioned with the left-right direction as its axial direction. The second flap portion 24 is attached to this second shaft 28.

[0035] As shown in Figures 9, 10, 13, and 14, the second flap portion 24 includes a second frame 60, one end of which is rotatably supported with respect to the second shaft 28, and a second lock 70 provided at one end of the second frame 60, which restricts the rotation of the second frame 60 with respect to the second shaft 28 and releases the restriction when the push button 92 of the second operating member 78 is operated.

[0036] As shown in Figures 9, 10, 13, and 14, the second frame 60 is composed of a frame body 62 formed in a substantially U-shape and a pair of left and right connecting brackets 64 fixed to both ends of the frame body 62. The frame body 62 is made of, for example, a bent metal pipe, and the left and right connecting brackets 64 are made of, for example, a press-formed metal plate. The left and right connecting brackets 64 are fixed to both ends of the frame body 62 by means of, for example, welding, and are arranged in a position where the left-right direction is the thickness direction.

[0037] The left and right connecting brackets 64 have circular through holes (not shown) into which the left and right ends of the second shaft 28 are inserted. As a result, the left and right connecting brackets 64, i.e., the second frame 60, are supported so as to be rotatable around the second shaft 28. A second pad 66 (see Figures 1 to 8) is attached to the second frame 60, and the second pad 66 is covered by a second skin 68 (see Figures 1 to 8). The second pad 66 is made of a foam material such as urethane foam, and the second skin 68 is made of multiple skin pieces made of, for example, cloth, leather, or synthetic leather, which are sewn together to form a bag.

[0038] The second lock 70 comprises a second ratchet member 72 fixed to the second shaft 28 on one side (the left side in this case) of the connecting bracket 64 and having ratchet teeth 72A formed thereon; a second lock member 74 displaceably (rotatably in this case) attached to one of the connecting brackets 64; a tension coil spring 76 as a second biasing member that biases the second lock member 74 in the direction of engagement with the ratchet teeth 72A of the second ratchet member 72; and a second operating member 78 that rotates the second lock member 74 relative to one of the connecting brackets 64.

[0039] The second ratchet member 72 is positioned to the right of one of the connecting brackets 64. This second ratchet member 72 is formed in a substantially disc shape from, for example, a metal plate, and is positioned with the left-right direction as its axis. Ratchet teeth 72A are formed on a part of the outer circumference of the second ratchet member 72. A circular through-hole (not shown) is formed in the center of the second ratchet member 72 through which the second shaft 28 is inserted. This second ratchet member 72 is fixed to the second shaft 28 by means of welding or other means. An E-ring 80 is positioned on the left side of one of the connecting brackets 64. By attaching this E-ring 80 to the second shaft 28, the axial displacement of one of the connecting brackets 64 relative to the second shaft 28 is restricted.

[0040] The second locking member 74 is composed of a lever member 82 positioned to the left of one connecting bracket 64, a locking plate 84 positioned to the right of one connecting bracket 64, and a connecting shaft 86 that penetrates the rear end of one connecting bracket 64 in the left-right direction.

[0041] The lever member 82 and the locking plate 84 are made of, for example, a press-formed metal plate. The lever member 82 is formed in a roughly L-shape when viewed from the left to right. One end of the connecting shaft 86 is fixed to the middle part of the lever member 82 by means of crimping or the like. The locking plate 84 is formed in a roughly L-shape when viewed from the left to right. The other end of the connecting shaft 86 is fixed to one end of the locking plate 84 by means of crimping or the like. As a result, the lever member 82 and the locking plate 84 are connected via the connecting shaft 86, and the lever member 82 and the locking plate 84 are configured to rotate integrally around the connecting shaft 86 relative to the connecting bracket 64.

[0042] One end of the lever member 82 is provided with a bent inclined portion 82A (see Figure 15), and one end of a tension coil spring 76 is locked to the other end of the lever member 82. The other end of the tension coil spring 76 is locked to one of the connecting brackets 64. The other end of the lock plate 84 has a claw portion 84A that protrudes toward the second ratchet member 72. The lock plate 84 and the lever member 82 are biased by the tension coil spring 76 in the engagement direction such that the claw portion 84A of the lock plate 84 engages (meets) with the ratchet teeth 72A of the second ratchet member 72. This engagement restricts the rotation of the second flap portion 24 relative to the second shaft 28. This rotation restriction can be released by operating the second operating member 78.

[0043] As shown in Figure 15, the second operating member 78 is positioned to the left of one of the connecting brackets 64. This second operating member 78 has a base portion 90 fixed to one of the connecting brackets 64 via a mounting bracket 88, and a push button 92 mounted on the base portion 90 so as to be displaceable in the left-right direction. The mounting bracket 88 is made of, for example, a press-formed metal plate and is fixed to one of the connecting brackets 64 by means of welding or other means. The base portion 90 is formed of, for example, resin in a bottomed cylindrical shape and is positioned on the opposite side of the mounting bracket 88 from one of the connecting brackets 64. This base portion 90 is positioned with its opening facing the mounting bracket 88 and is fixed to the mounting bracket 88 by means of adhesive or other means.

[0044] The push button 92 is composed of a cylindrical rod-shaped portion 92A and a substantially disc-shaped button portion 92B fixed to one end of the rod-shaped portion 92A. The rod-shaped portion 92A is positioned with its axis oriented in the left-right direction and is inserted through through holes (reference numerals omitted) formed in the bottom wall of the base portion 90 and the mounting bracket 88. This rod-shaped portion 92A is designed to be displaceable in the axial direction within a certain range relative to the base portion 90.

[0045] The button portion 92B is positioned on the opposite side of the mounting bracket 88 via the base portion 90 and is fixed to one end of the rod-shaped portion 92A by means of adhesive or other means. As shown in Figures 2 to 8, the button portion 92B is positioned exposed to the outside of the second flap portion 24 from the left side of the second flap portion 24. The other end of the rod-shaped portion 92A abuts against the inclined portion 82A of the lever member 82. This push button 92 is biased toward the opposite side of the inclined portion 82A by a compression coil spring 94 located inside the base portion 90. When this push button 92 is pushed toward the inclined portion 82A, the other end of the rod-shaped portion 92A slides against the inclined portion 82A, causing the lock plate 84 and the lever member 82 to rotate in the opposite direction to the engagement direction with the ratchet teeth 72A of the second ratchet member 72. This configuration releases the engagement between the claw portion 84A of the locking plate 84 and the ratchet teeth 72A (i.e., the rotational restriction of the second flap portion 24 relative to the second shaft 28).

[0046] In the ottoman 20 with the above configuration, when the first flap portion 22 is moved from the retracted state to the unfolded state, the first flap portion 22 rotates forward around the first axis 26 together with the second flap portion 24. At this time, the orientation of the ratchet teeth 44A is set so that the claw portion 56A of the locking plate 56 can overcome the ratchet teeth 44A of the first ratchet member 44. When the first flap portion 22 is unfolded, the position of the first flap portion 22 can be adjusted in multiple stages. The direction of rotation of the first flap portion 22 from the retracted state to the unfolded state is clockwise when viewed from the left side. On the other hand, when the first flap portion 22 is moved from the unfolded state to the retracted state, the strap 50 is pulled, which allows the rotation of the first flap portion 22 to the retracted state.

[0047] When the second flap section 24 is moved from the retracted state to the deployed state or the luggage stopper state, the second flap section 24 is rotated forward around the second shaft 28. At this time, the orientation of the ratchet teeth 72A is set so that the claw portion 84A of the lock plate 84 can overcome the ratchet teeth 72A of the second ratchet member 72. In the deployed state of the second flap section 24, the position of the second flap section 24 can be adjusted in multiple stages. The direction of rotation of the second flap section 24 from the retracted state to the deployed state or the luggage stopper state is clockwise when viewed from the left side. On the other hand, when the second flap section 24 is moved from the deployed state or the luggage stopper state to the retracted state, the push button 92 of the second operating member 78 is pressed, which allows the rotation of the second flap section 24 to the retracted state.

[0048] Next, the operation and effects of this embodiment will be described.

[0049] In the vehicle seat 10 with the above configuration, the back of the occupant seated on the seat cushion 12 is supported by the seat back 14. An ottoman 20 with a first flap portion 22 and a second flap portion 24 is provided at the front end of the seat cushion 12. The first flap portion 22 is rotatably connected to the front end of the seat cushion 12 around a first axis 26 that is aligned in the left-right direction. This first flap portion 22 can be in a retracted state, extending downward from the front end of the seat cushion 12, or in an extended state, extending forward from the front end of the seat cushion 12.

[0050] The second flap portion 24 is positioned on the opposite side of the front end of the seat cushion 12 from the first flap portion 22. The second flap portion 24 has a connecting portion 24A that is rotatably connected to the first flap portion 22 around a second axis 28 that is aligned in the left-right direction, and an extension portion 24B that extends radially outward from the connecting portion 24A along the second axis 28. The second flap portion 24 can be in a stowed state in which the extension portion 24B overlaps the back surface of the first flap portion 22, and in an extended state in which the extension portion 24B extends forward of the first flap portion 22 in its extended state.

[0051] When the first flap section 22 and the second flap section 24 are retracted, the extension 24B of the second flap section 24 overlaps the back of the first flap section 22 as described above, allowing the ottoman 20 to be stored compactly. Furthermore, when the first flap section 22 and the second flap section 24 are deployed, the second flap section 24 extends forward of the first flap section 22, providing stable support for the occupant's knees and calves with a sufficiently long extension. Moreover, no gap is created between the first flap section 22 and the second flap section 24 when deployed. As a result, the support for the occupant's calves is improved.

[0052] Furthermore, in this embodiment, when the second flap portion 24 is in a luggage stopper state while the first flap portion 22 is deployed, the extension portion 24B of the second flap portion extends upward toward the first flap portion 22. As a result, the extension portion 24B of the second flap portion 24 can be used as a stopper for luggage placed on the seat cushion 12.

[0053] Furthermore, in this embodiment, one end of the first frame 34 of the first flap portion 22 is rotatably supported on the first shaft 26, and the second shaft 28 is fixed to the other end of the first frame 34. A first lock 42 is provided on one end of the first frame 34. This first lock 42 restricts the rotation of the first frame 34 relative to the first shaft 26. This prevents unintended rotation of the first flap portion 22 relative to the first shaft 26. In addition, the first lock 42 is released when the strap 50 is pulled, so that rotation of the first flap portion 22 relative to the first shaft 26 is permitted.

[0054] Furthermore, in this embodiment, one end of the second frame 60 of the second flap portion 24 is rotatably supported with respect to the second shaft 28. A second lock 70 is provided at one end of the second frame 60. This second lock 70 restricts the rotation of the second frame 60 with respect to the second shaft 28. This prevents unintended rotation of the second flap portion 24 with respect to the second shaft 28. In addition, the second lock 70 is released when the push button 92 is pressed, so that rotation of the second flap portion 24 with respect to the second shaft 28 is permitted.

[0055] Furthermore, in this embodiment, the rotation direction when deploying the first flap section 22 and the second flap section 24 is the same (clockwise when viewed from the left). Also, there is no need to operate the strap 50 or the push button 92 to deploy the first flap section 22 and the second flap section 24. Therefore, the operation of deploying the first flap section 22 and the second flap section 24 is easy. Moreover, when deploying the second flap section 24, the occupant does not need to lift or move their feet, so the deployment operation is easy in this respect as well.

[0056] In the above embodiment, the present invention was described in the case where it is applied to a vehicle seat, but the present invention is not limited to this and can also be applied to seats for vehicles other than vehicles (for example, aircraft and ships).

[0057] Furthermore, the present invention can be implemented with various modifications without departing from its spirit. Of course, the scope of the present invention is not limited to the embodiments described above. [Explanation of Symbols]
