Modes for Carrying Out the Invention
[0027] The vehicle seat 10 according to an embodiment of the present invention will be described below with reference to Figures 1 to 6. 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.
[0028] As shown in Figure 1, 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 above 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 (see Figure 3) is formed at the front end of the seat cushion 12, and the storage recess 12A is open to the front, top, and bottom.
[0029] An ottoman device 16 is provided at the front of the seat cushion 12.
[0030] The ottoman device 16 is provided with a moving mechanism 18 (see Figure 2(A)), which is installed on the rear side of the storage recess 12A in the seat cushion 12.
[0031] An ottoman 20 is supported at the front end of the moving mechanism 18, and the ottoman 20 is stored in the storage recess 12A of the seat cushion 12.
[0032] The ottoman 20 is provided with a roughly rectangular flap base 22 (see Figure 6) as a support, and the upper part of the flap base 22 is supported at the front end of the moving mechanism 18, so the ottoman 20 is supported at the front end of the moving mechanism 18.
[0033] The ottoman body 24 (see Figure 2(A)) is supported by the flap base 22. The ottoman body 24 is provided with a roughly rectangular flap plate 26 (see Figure 4(A)) as a sliding member, and the flap plate 26 is supported by the flap base 22, and the ottoman body 24 is supported by the flap base 22. A pad 28 is attached to the front and upper side of the flap plate 26, and the pad 28 is made of a foam material such as urethane and has elasticity. The front side of the pad 28 is covered with a surface material 30, and the surface material 30 is made of fabric, leather or synthetic leather and has flexibility.
[0034] The flap plate 26 is supported on the flap base 22 so as to be slidable in the vertical direction, and a locking mechanism 32 (see Figure 5(A)) is provided between the flap base 22 and the flap plate 26.
[0035] Rectangular locking holes 22A are formed through the center of the flap base 22 in the left-right direction, at the top and bottom, and the locking holes 22A are spaced apart in the vertical direction.
[0036] At the left-right center of the flap plate 26, cylindrical insertion pins 26A are integrally provided at the top and bottom, serving as guide parts that constitute a guide mechanism, and the insertion pins 26A protrude to the rear. At the left-right center of the flap plate 26, cylindrical guide pins 26B are integrally provided vertically inward from each insertion pin 26A, serving as limiting parts that constitute a limiting mechanism, and the guide pins 26B protrude to the rear.
[0037] A roughly elongated rectangular plate-shaped lock plate 34 (see Figure 6) is positioned behind the center of the flap plate 26 in the left-right direction, and the lock plate 34 extends in the vertical direction. Circular insertion holes 34A, which constitute the guided portion of the guide mechanism, are formed through the upper and lower parts of the lock plate 34, and the insertion pins 26A of the flap plate 26 are fitted into the insertion holes 34A. Circular guide holes 34B, which constitute the restricted portion of the limiting mechanism, are formed through the lock plate 34, vertically inward from each insertion hole 34A, and the guide pins 26B of the flap plate 26 are fitted into the guide holes 34B. As a result, the vertical and horizontal movement of the insertion holes 34A relative to the insertion pins 26A is restricted, and the vertical and horizontal movement of the guide holes 34B relative to the guide pins 26B is restricted, thereby restricting the vertical and horizontal movement of the lock plate 34 relative to the flap plate 26. Furthermore, the insertion hole 34A is made movable in the front-rear direction along the insertion pin 26A, and the guide hole 34B is made movable in the front-rear direction along the guide pin 26B, so that the lock plate 34 is movable in the front-rear direction relative to the flap plate 26.
[0038] The insertion pin 26A of the flap plate 26 is inserted into a coil spring 36 (see Figure 6) which acts as a biasing member. The coil spring 36 is stretched between the flap plate 26 and the lock plate 34 and is compressed to bias the lock plate 34 backward.
[0039] Rectangular columnar lock pins 34C are integrally provided at the upper and lower ends of the lock plate 34 as locking parts, and the lock pins 34C protrude to the rear. The upper and lower lock pins 34C are fitted (engaged) into the upper and lower lock holes 22A of the flap base 22, respectively. This locks the vertical movement of the lock pins 34C relative to the lock holes 22A, locks the vertical sliding of the lock plate 34 relative to the flap base 22, locks the vertical sliding of the flap plate 26 relative to the flap base 22, and locks the vertical sliding of the ottoman body 24 relative to the flap base 22.
[0040] The rear end (base end) of a strip-shaped strap 38, which serves as an operating member, is connected to the center of the lock plate 34 in both the vertical and horizontal directions. The strap 38 is flexible and bendable. The strap 38 penetrates the ottoman body 24 (flap plate 26, pad 28, and surface material 30), and the front end (tip) of the strap 38 protrudes to the front of the ottoman body 24 and is formed in an annular shape.
[0041] Next, the operation of this embodiment will be explained.
[0042] In the vehicle seat 10 with the above configuration, the ottoman device 16 stores the ottoman 20 (flap base 22 and ottoman body 24) in the storage recess 12A of the seat cushion 12. In addition, the locking mechanism 32 has upper and lower locking pins 34C of the ottoman body 24 (locking plate 34) fitted into upper and lower locking holes 22A of the flap base 22, respectively, locking the vertical sliding of the ottoman body 24 relative to the flap base 22.
[0043] When the moving mechanism 18 is deployed, the ottoman 20 is moved forward and rotated forward around its upper part by the moving mechanism 18, so that the ottoman 20 is deployed in front of the seat cushion 12 (see Figure 2(A)). As a result, the ottoman body 24 can support the lower legs L of the occupant P who is seated on the seat cushion 12.
[0044] Furthermore, with the ottoman 20 extended in front of the seat cushion 12, in the locking mechanism 32, the strap 38 is pulled forward by the occupant P, causing the lock plate 34 to move forward against the biasing force of the coil spring 36. This disengages the lock pin 34C of the lock plate 34 from the lock hole 22A of the flap base 22, unlocking the vertical sliding of the ottoman body 24 relative to the flap base 22. Subsequently, the strap 38 is pulled downward by the occupant P, causing the ottoman body 24 to slide downward relative to the flap base 22. After this, the pull of the strap 38 by the occupant P is released, and the lock plate 34 moves backward due to the biasing force of the coil spring 36. This causes the upper lock pin 34C of the lock plate 34 to engage with the lower lock hole 22A of the flap base 22, locking the vertical sliding of the ottoman body 24 relative to the flap base 22 (see Figures 2(B), 4(B), and 5(B)). Therefore, the position of the ottoman body 24, which supports the lower leg L of the occupant P sitting on the seat cushion 12, is changed to the lower side.
[0045] Here, with the ottoman 20 stored in the storage recess 12A of the seat cushion 12, the locking mechanism 32 is pulled forward by the occupant P, causing the lock plate 34 to move forward against the biasing force of the coil spring 36. This causes the lock pin 34C of the lock plate 34 to disengage from the lock hole 22A of the flap base 22, and the vertical sliding of the ottoman body 24 relative to the flap base 22 is unlocked. Furthermore, after the strap 38 is pulled upward by the occupant P, causing the ottoman body 24 to slide upward relative to the flap base 22, the occupant P's pull on the strap 38 is released, and the lock plate 34 is moved rearward by the biasing force of the coil spring 36. This causes the lock pin 34C on the lower side of the lock plate 34 to fit into the lock hole 22A on the upper side of the flap base 22, locking the vertical sliding of the ottoman body 24 relative to the flap base 22 (see Figures 2(C), 3, 4(C), and 5(C)). As a result, the ottoman body 24 protrudes above the seat cushion 12, preventing luggage (objects) on the seat cushion 12 from falling to the front of the seat cushion 12.
[0046] Furthermore, in the locking mechanism 32, the upper and lower locking pins 34C of the ottoman body 24 (locking plate 34) are fitted into the upper and lower locking holes 22A of the flap base 22, respectively, locking the ottoman body 24 to the initial position relative to the flap base 22. In addition, the upper locking pin 34C of the ottoman body 24 is fitted into the lower locking hole 22A of the flap base 22, locking the ottoman body 24 to the lower position relative to the flap base 22. Moreover, the lower locking pin 34C of the ottoman body 24 is fitted into the upper locking hole 22A of the flap base 22, locking the ottoman body 24 to the upper position relative to the flap base 22. As a result, the vertical sliding of the ottoman body 24 relative to the flap base 22 can be locked in three positions (initial position, lower position, and upper position).
[0047] Furthermore, in the locking mechanism 32, the insertion pin 26A of the flap plate 26 is fitted into the insertion hole 34A of the lock plate 34 in the ottoman body 24. When the lock plate 34 is moved forward and backward relative to the flap plate 26, the insertion hole 34A is guided by the insertion pin 26A. As a result, the forward and backward movement of the lock plate 34 relative to the flap plate 26 is guided, allowing the lock plate 34 to move appropriately forward and backward relative to the flap plate 26.
[0048] Furthermore, in the locking mechanism 32, the guide pin 26B of the flap plate 26 is fitted into the guide hole 34B of the lock plate 34 in the ottoman body 24. When the lock plate 34 is moved forward and backward relative to the flap plate 26, the guide pin 26B restricts the tilting of the guide hole 34B, thereby restricting the tilting of the lock plate 34 relative to the flap plate 26. This prevents the lock plate 34 from being forced and becoming immobile, and allows the lock plate 34 to move appropriately forward and backward relative to the flap plate 26.
[0049] Furthermore, in the locking mechanism 32, the strap 38 is connected to the locking plate 34, and when the strap 38 is pulled (operated) to the rear, the locking plate 34 moves to the rear, thereby unlocking the sliding of the ottoman body 24 relative to the flap base 22. Therefore, the sliding of the ottoman body 24 relative to the flap base 22 can be easily unlocked.
[0050] Furthermore, the strap 38 is bendable. Therefore, when the strap 38 is pulled to the rear, unlocking the sliding of the ottoman body 24 relative to the flap base 22, the strap 38 can be bent and pulled downwards and upwards, allowing the ottoman body 24 to slide downwards and upwards relative to the flap base 22, respectively. This makes it easy to slide the ottoman body 24 downwards and upwards relative to the flap base 22.
[0051] Furthermore, the only additional components for the locking mechanism 32 are the lock plate 34, the coil spring 36, and the strap 38. This allows for a reduction in the number of parts, a reduction in the space required for the locking mechanism 32, and a reduction in cost.
[0052] In this embodiment, the vertical sliding of the ottoman body 24 relative to the flap base 22 is locked in three positions: the initial position, the lower position, and the upper position. However, the vertical sliding of the ottoman body 24 relative to the flap base 22 may be locked in two positions: the initial position and the upper position.
[0053] Furthermore, in this embodiment, the flap plate 26 is provided with an insertion pin 26A (guide portion), and the lock plate 34 is provided with an insertion hole 34A (guided portion). However, the flap plate 26 may be provided with an insertion hole 34A (guide portion), and the lock plate 34 may be provided with an insertion pin 26A (guided portion).
[0054] Furthermore, in this embodiment, the flap plate 26 is provided with a guide pin 26B (restricting portion), and the lock plate 34 is provided with a guide hole 34B (restricted portion). However, the flap plate 26 may be provided with a guide hole 34B (restricting portion), and the lock plate 34 may be provided with a guide pin 26B (restricted portion).
[0055] In this embodiment, the lock plate 34 is provided with a lock pin 34C (locked portion), and the flap base 22 is provided with a lock hole 22A (locking portion). However, the lock plate 34 may be provided with a lock hole 22A (locked portion), and the flap base 22 may be provided with a lock pin 34C (locking portion).
[0056] Furthermore, this embodiment described the case in which the present invention is applied 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]
