[0023] [First Embodiment] A vehicle seat 10 according to the first embodiment of the present invention will be described with reference to Figures 1 to 9. In each figure, the front of the vehicle seat 10 is indicated by the arrow FR, the top of the vehicle seat 10 is indicated by the arrow UP, and the right side (one side in the width direction) of the vehicle seat 10 is indicated by the arrow RH.

[0024] As shown in Figures 1 and 2, a seat cushion 12 is provided at the lower end of the vehicle seat 10, and an occupant P sits on the seat cushion 12. A seat back 14 is provided on the upper side of the rear end of the seat cushion 12, and the seat back 14 supports the back of the occupant P. A roughly rectangular storage recess 12A is formed at the front end of the seat cushion 12, and the storage recess 12A is open on the front, top, and bottom sides.

[0025] An ottoman device 16 (see Figure 6) is provided at the front of the seat cushion 12 as a foot support device.

[0026] The ottoman device 16 is provided with a moving mechanism 18. The moving mechanism 18 is provided with a roughly U-shaped plate-like support plate 20 as a support member. The support plate 20 is fixed to the rear side of the storage recess 12A in the seat cushion 12, and its interior is open to the front. Roughly rectangular frame-shaped guide plates 20A are integrally provided on the left and right sides of the support plate 20, and the guide plates 20A are arranged vertically in the left-right direction. Long guide holes 20B are formed through the guide plates 20A, and the guide holes 20B extend upward as they are directed forward.

[0027] A substantially rectangular plate-shaped slide plate 22 (see Figures 8(A) and 9(A)) is supported on the upper side of the support plate 20 as an engaging member, and the slide plate 22 is slidable in the front-rear direction relative to the support plate 20. A rectangular through hole 22A is formed through the center of the front end of the slide plate 22 in the left-right direction, and the front surface of the through hole 22A is inclined upward and curved convexly as it extends forward, while the rear surface of the through hole 22A is curved convexly toward the front.

[0028] Near the front end of the slide plate 22, the left and right sides are rotatably supported at the bottom by the middle portion of a roughly rectangular plate-shaped connecting plate 24 (see Figure 7), which serves as a connecting member. The rear end of the connecting plate 24 is rotatably and slidably supported by the rear end of the guide hole 20B of the guide plate 20A.

[0029] An ottoman 26, which serves as a foot support member, is supported on the front side of the moving mechanism 18, and the ottoman 26 is stored in the storage recess 12A of the seat cushion 12.

[0030] A roughly rectangular base plate 28 is provided as a base member on the rear portion of the ottoman 26. The left and right upper ends of the base plate 28 are rotatably supported by the left and right front ends of the slide plate 22, respectively, and the left and right near the upper end of the base plate 28 are rotatably supported by the front ends of the left and right connecting plates 24, respectively. As a result, when the slide plate 22 slides forward relative to the support plate 20, and the connecting plate 24 moves forward while sliding its rear end forward along the guide hole 20B of the guide plate 20A, the ottoman 26 (base plate 28) moves forward and rotates forward and upward around its top to unfold (see Figure 7). Subsequently, the slide plate 22 slides to the rear relative to the support plate 20, and the connecting plate 24 moves to the rear while sliding its rear end along the guide hole 20B of the guide plate 20A, causing the ottoman 26 (base plate 28) to move to the rear and rotate to the rear and downward around its top, and be stored (see Figure 6).

[0031] A pad 30 is attached to the front and upper side of the base plate 28. The pad 30 is made of a foam material such as urethane and has elasticity. The front side of the pad 30 is covered with a surface material 32. The surface material 32 is made of fabric, leather, or synthetic leather and has flexibility.

[0032] A locking device 34 (see Figure 8(A)) is provided between the base plate 28 and the slide plate 22.

[0033] A long, roughly rectangular strap holder 36 is positioned in the center of the lower surface of the slide plate 22 in the left-right direction, serving as a connecting member. The strap holder 36 extends in the front-rear direction. On the lower surface of the slide plate 22, L-shaped retaining claws 22B (see Figure 9(C)) are integrally provided on the front and rear left and right sides of the strap holder 36, serving as retaining parts. The upper portion (base end portion) of the retaining claws 22B protrudes downward, while the lower portion (tip portion) of the retaining claws 22B protrudes toward the strap holder 36. The strap holder 36 is fitted between the left and right retaining claws 22B, and the strap holder 36 is held by the slide plate 22 by the retaining claws 22B and is guided by the retaining claws 22B to move within a predetermined range in the front-rear direction relative to the slide plate 22.

[0034] A coil spring 38, acting as a biasing member, is stretched between the strap holder 36 and the slide plate 22. The coil spring 38 is compressed, biasing the strap holder 36 backward relative to the slide plate 22.

[0035] The thickness of the rear of the strap holder 36 has been reduced, and a gap has been formed between the rear of the strap holder 36 and the slide plate 22 (see Figure 9(B)). A long cam hole 36A is formed through the rear of the strap holder 36, and the cam hole 36A extends to the left as it approaches the rear, and is curved convexly to the rear and to the right.

[0036] A roughly rectangular plate-shaped lock plate 40 is held between the rear of the strap holder 36 and the slide plate 22 as a movable member. Cylindrical movable pins 40A are integrally provided on the front and rear of the upper surface of the lock plate 40, and the movable pins 40A protrude upward. On the lower surface of the slide plate 22, a movable groove 22C with a rectangular cross-section is formed above the front and rear of the lock plate 40, and the movable groove 22C extends in the left-right direction. The movable pins 40A of the lock plate 40 are inserted into the movable groove 22C and fitted in the front-rear direction, thereby restricting the movement of the lock plate 40 in the front-rear direction relative to the slide plate 22, and allowing the movable pins 40A to move along the movable groove 22C, thereby moving the lock plate 40 in the left-right direction.

[0037] A cylindrical cam pin 40B is integrally provided on the lower surface of the lock plate 40. The cam pin 40B protrudes downward and is inserted into the front end of the cam hole 36A of the strap holder 36, fitting in the width direction of the cam hole 36A. When the strap holder 36 is moved forward relative to the slide plate 22, the cam pin 40B moves toward the rear end of the cam hole 36A, and the lock plate 40 moves to the left (see Figure 8(B)). When the strap holder 36 is moved backward relative to the slide plate 22, the cam pin 40B moves toward the front end of the cam hole 36A, and the lock plate 40 moves to the right (see Figure 8(A)). Multiple locking teeth 40C are formed on the right end of the lock plate 40, and the multiple locking teeth 40C are arranged in the front-to-back direction.

[0038] The support plate 20 is provided with multiple locking teeth (not shown) integrally, and the locking teeth are arranged in the front-to-back direction. The locked teeth 40C of the lock plate 40 engage with the locking teeth, thereby locking the movement of the lock plate 40 in the front-to-back direction, and thus locking the sliding of the slide plate 22 in the front-to-back direction. When the lock plate 40 is moved to the left, the engagement of the locked teeth 40C with the locking teeth is released, unlocking the movement of the lock plate 40 in the front-to-back direction, and thus unlocking the sliding of the slide plate 22 in the front-to-back direction.

[0039] The base end of a strip-shaped strap 42 (see Figure 9(A)), which serves as an operating member, is connected to the front end of the strap holder 36, and the strap 42 is flexible. The strap 42 is inserted through the insertion hole 22A of the slide plate 22 and extends to the upper side of the slide plate 22, and the tip of the strap 42 is formed in an annular shape. When the tip of the strap 42 is pulled forward, the strap 42 slides against the front surface of the insertion hole 22A, for example, and the strap holder 36 is moved forward relative to the slide plate 22 by the strap 42. When the tip of the strap 42 is pulled backward, the strap 42 slides against the rear surface of the insertion hole 22A in a curved state, and the strap holder 36 is moved forward relative to the slide plate 22 by the strap 42.

[0040] Next, the operation of this embodiment will be explained.

[0041] In the vehicle seat 10 with the above configuration, the ottoman 26 is stored in the storage recess 12A of the seat cushion 12 in the ottoman device 16. In addition, in the locking device 34, the locking teeth 40C of the locking plate 40 engage with the locking teeth of the support plate 20, locking the movement of the locking plate 40 in the front-rear direction, thereby locking the sliding of the slide plate 22 of the moving mechanism 18 in the front-rear direction, and thus locking the movement of the ottoman 26 in the front-rear direction.

[0042] When the tip of the strap 42 is pulled forward, the strap 42 slides against the front surface of the insertion hole 22A of the slide plate 22, for example, and the strap holder 36 is moved forward relative to the slide plate 22 against the biasing force of the coil spring 38 by the strap 42, causing the lock plate 40 to move to the left. As a result, the engagement of the locked teeth 40C with the lock teeth is released, and the movement of the lock plate 40 in the front-rear direction is unlocked, which in turn unlocks the sliding of the slide plate 22 in the front-rear direction, and thus unlocks the movement of the ottoman 26 in the front-rear direction. Then, the slide plate 22 slides forward together with the strap holder 36 by the strap 42, causing the ottoman 26 to move forward and unfold (see Figure 7).

[0043] Subsequently, when the forward pulling operation of the tip of the strap 42 is released, the strap holder 36 is moved rearward relative to the slide plate 22 by the biasing force of the coil spring 38, and the lock plate 40 is moved to the right. As a result, the locking teeth 40C engage with the locking teeth, locking the movement of the lock plate 40 in the front-rear direction, which in turn locks the sliding of the slide plate 22 in the front-rear direction, and locks the ottoman 26 in the extended position. This allows the ottoman 26 to support the lower leg L of the occupant P seated on the seat cushion 12.

[0044] When the tip of the strap 42 is pulled to the rear, the strap 42 slides against the rear surface of the insertion hole 22A, and the strap 42 moves the strap holder 36 forward relative to the slide plate 22 against the biasing force of the coil spring 38, causing the lock plate 40 to move to the left. As a result, the engagement of the locked teeth 40C with the lock teeth is released, and the movement of the lock plate 40 in the front-rear direction is unlocked, which in turn unlocks the sliding of the slide plate 22 in the front-rear direction, and thus unlocks the movement of the ottoman 26 in the front-rear direction. Then, the rear surface of the insertion hole 22A is pressed to the rear by the strap 42, and the slide plate 22 slides to the rear together with the strap holder 36, causing the ottoman 26 to move to the rear and be stored (see Figure 6).

[0045] Subsequently, when the pulling operation of the tip of the strap 42 toward the rear is released, the strap holder 36 is moved toward the rear relative to the slide plate 22 by the biasing force of the coil spring 38, and the lock plate 40 is moved to the right. As a result, the locking teeth 40C engage with the locking teeth, locking the movement of the lock plate 40 in the front-to-back direction, which in turn locks the sliding of the slide plate 22 in the front-to-back direction, and locks the ottoman 26 in the stored position.

[0046] As described above, when the tip of the strap 42 is pulled forward and backward, the movement of the slide plate 22 and the ottoman 26 are unlocked, respectively, and the ottoman 26 is extended and retracted. Therefore, the ottoman 26 can be extended and retracted simply by pulling the tip of the strap 42, making it easy to extend and retract the ottoman 26. Moreover, not only can an occupant P who is not seated on the seat cushion 12 extend and retract the ottoman 26 by pulling the tip of the strap 42 forward and backward with one hand (see Figures 3 and 4), but an occupant P seated on the seat cushion 12 can also extend and retract the ottoman 26 by pulling the tip of the strap 42 forward and backward with one hand through the space between the lower legs L (see Figures 5(A) and (B)). Furthermore, by making the direction of pulling the tip of the strap 42 the same as the direction of extending and retracting the ottoman 26, the extension and retraction of the ottoman 26 can be performed with intuitive operation.

[0047] Furthermore, the base end of the strap 42 is connected to the strap holder 36, and when the tip of the strap 42 is pulled, the strap holder 36 is moved forward, and the movement of the ottoman 26 is unlocked. Therefore, the movement of the ottoman 26 can be unlocked by pulling the tip of the strap 42.

[0048] Furthermore, in the locking device 34, the cam pin 40B of the lock plate 40 is inserted into the cam hole 36A of the strap holder 36. When the strap holder 36 moves in the front-to-back direction, the lock plate 40 moves in the left-to-right direction, thereby locking and unlocking the movement of the ottoman 26. This simplifies the configuration of the locking device 34 and reduces its cost.

[0049] Furthermore, in the moving mechanism 18, the slide plate 22 and the connecting plate 24 rotatably support the ottoman 26. When the tip of the strap 42 is pulled, the slide plate 22 and the connecting plate 24 move forward and backward, respectively, causing the ottoman 26 to move forward and backward, and rotate forward and upward and backward and downward. Therefore, the ottoman 26 can be rotated simply by pulling the tip of the strap 42, making it easy to rotate the ottoman 26.

[0050] Furthermore, the ottoman device 16 is a mechanical device and does not have any electrical components. Therefore, the ottoman device 16 can be made lighter, less expensive, and more space-saving.

[0051] [Second Embodiment] A vehicle seat 50 according to a second embodiment of the present invention will be described using Figures 10(A) and 10(B).

[0052] The vehicle seat 50 according to this embodiment has substantially the same configuration as that of the first embodiment described above, but differs in the following respects.

[0053] As shown in Figures 10(A) and (B), in the ottoman device 16 of the vehicle seat 50 according to this embodiment, a long retaining hole 36B is formed through the front of the strap holder 36 in the locking device 34, and the retaining hole 36B extends in the front-rear direction. The portion of a substantially cylindrical bush 52, which serves as an intermediate member, other than the lower end is inserted into the retaining hole 36B, and the portion of the bush 52 other than the lower end is fitted into the retaining hole 36B in the left-right direction. The outer circumference of the lower end of the bush 52 is enlarged in diameter, and the lower end of the bush 52 abuts against the strap holder 36. The legs of a bolt 54, which serves as a regulating member, are fitted into the bush 52 from below, and the head of the bolt 54 (for example, a hole for a wrench is provided) is rotated so that the legs of the bolt 54 are screwed (connected) to the slide plate 22 of the moving mechanism 18. The lower end of the bush 52 is fitted between the head of the bolt 54 and the strap holder 36, and the strap holder 36 and the bush 52 are held to the slide plate 22 by the bolt 54. The strap holder 36 is made movable relative to the slide plate 22 by allowing the circumferential surface of the holding hole 36B to slide against the bush 52.

[0054] On the lower surface of the slide plate 22, rectangular cross-section guides 22D are integrally provided on the left and right sides of the strap holder 36, replacing the retaining claws 22B. The guides 22D protrude downward. The guides 22D extend in the front-rear direction and are not provided in the area where the lock plate 40 is positioned. The strap holder 36 is fitted between the left and right guides 22D, and the strap holder 36 is guided by the guides 22D so that it can move in the front-rear direction within a predetermined range relative to the slide plate 22.

[0055] In this embodiment, the same effects and advantages as those of the first embodiment can be achieved.

[0056] Furthermore, when the strap holder 36 and lock plate 40 are assembled to the slide plate 22, the movable pin 40A of the lock plate 40 is inserted into the movable groove 22C of the slide plate 22. Then, the strap holder 36 is fitted between the guides 22D of the slide plate 22, and the cam pin 40B of the lock plate 40 is inserted into the cam hole 36A of the strap holder 36. Then, the portion of the bush 52 other than the lower end is inserted into the retaining hole 36B of the strap holder 36, and the legs of the bolt 54 are fitted into the bush 52 (through the retaining hole 36B), and the legs of the bolt 54 are screwed into the slide plate 22. Also, a coil spring 38 (not shown in Figure 10(A)) is placed between the slide plate 22 and the strap holder 36.

[0057] Therefore, even when it is necessary to insert (engage) the movable pin 40A of the lock plate 40 into the movable groove 22C of the slide plate 22, and to insert (engage) the cam pin 40B of the lock plate 40 into the cam hole 36A of the strap holder 36, the strap holder 36 can be fitted (engaged) between the guides 22D of the slide plate 22 from a direction perpendicular to the slide plate 22, thereby engaging the lock plate 40 with the slide plate 22 and the strap holder 36. Moreover, the bolt 54 restricts the detachment of the bush 52 and the strap holder 36 from the slide plate 22, and the slide plate 22 restricts the detachment of the lock plate 40 from the slide plate 22, making it easy to restrict the detachment of the bush 52, the strap holder 36, and the lock plate 40 from the slide plate 22. As a result, the bush 52, the strap holder 36, and the lock plate 40 can be easily assembled to the slide plate 22.

[0058] [Third Embodiment] A vehicle seat 60 according to a third embodiment of the present invention will be described using Figures 11(A) and 11(B).

[0059] The vehicle seat 60 according to this embodiment has substantially the same configuration as that of the first embodiment described above, but differs in the following respects.

[0060] As shown in Figures 11(A) and (B), in the ottoman device 16 of the vehicle seat 60 according to this embodiment, the locking device 34 does not have a cam pin 40B on the lock plate 40. The legs of a bolt 62, which serves as a connecting member, are inserted (through) into the front end of the cam hole 36A of the strap holder 36 and fitted in the width direction of the cam hole 36A. The head of the bolt 62 (for example, a hole for a wrench is provided) is rotated so that the legs of the bolt 62 are screwed (connected) to the lock plate 40. The strap holder 36 is fitted between the head of the bolt 62 and the lock plate 40, and the lock plate 40 is held in place by the bolt 62 in the strap holder 36.

[0061] When the strap holder 36 is moved forward relative to the slide plate 22, the bolt 62 is moved towards the rear end of the cam hole 36A, and the lock plate 40 is moved to the left. When the strap holder 36 is moved backward relative to the slide plate 22, the bolt 62 is moved towards the front end of the cam hole 36A, and the lock plate 40 is moved to the right.

[0062] In this embodiment, the same effects and advantages as those of the first embodiment can be achieved.

[0063] Furthermore, when the strap holder 36 and lock plate 40 are assembled to the slide plate 22, the movable pin 40A of the lock plate 40 is inserted (engaged) into the movable groove 22C of the slide plate 22. Then, the strap holder 36 is fitted (engaged) between the retaining claws 22B of the slide plate 22. Then, the legs of the bolt 62 are inserted (engaged) into the cam hole 36A of the strap holder 36, and the legs of the bolt 62 are screwed into the lock plate 40. Also, a coil spring 38 is placed between the slide plate 22 and the strap holder 36.

[0064] Therefore, even when the strap holder 36 is fitted between the retaining claws 22B of the slide plate 22 and the lock plate 40 has difficulty engaging with the strap holder 36, the bolt 62 is inserted into the cam hole 36A of the strap holder 36 and coupled to the lock plate 40, allowing the lock plate 40 to engage with the strap holder 36 via the bolt 62, thus enabling easy engagement of the lock plate 40 with the strap holder 36. This allows the strap holder 36 and the lock plate 40 to be easily assembled to the slide plate 22.

[0065] In the first to third embodiments described above, the tip of the strap 42 is pulled to the rear, which unlocks the slide plate 22 and stores the ottoman 26. However, the tip of the strap 42 may be pulled to the front or upward to unlock the slide plate 22, and then the tip of the strap 42 may be pulled to the rear to store the ottoman 26.

[0066] Furthermore, in the first to third embodiments described above, the ottoman 26 (foot support member) rotates when it is extended and retracted. However, the foot support member does not necessarily have to rotate when it is extended and retracted. For example, the length of the seat cushion 12 may be changed by the foot support member as it moves linearly when it is extended and retracted.

[0067] Furthermore, the first to third embodiments described above illustrate the application of the present invention to seats for vehicles. However, the present invention is also applicable to seats for vehicles other than vehicles (e.g., aircraft and ships). [Explanation of Symbols]
