Summary of the Invention

Problems to be Solved by the Invention

[0005] When a cable is routed inside the seat back as in the vehicle seat disclosed in Patent Document 1 above, it is necessary to satisfy the requirement for the minimum bending radius of the cable. In this regard, for example, in the seat back of the vehicle seat disclosed in Patent Document 2 above, when routing a cable across the back main body part and the back movable part, since the space where the cable can be routed is narrow, it may be difficult to satisfy the requirement for the minimum bending radius.

[0006] The present invention aims to provide a vehicle seat that facilitates cable routing even when the cable routing space is limited. [Means for solving the problem]

[0007] A vehicle seat according to a first embodiment includes: a seat movable part that is displaceable between a first position and a second position relative to the vehicle; a locking device provided on the seat movable part; a movable striker provided on an adjacent part positioned adjacent to the seat movable part when the seat movable part is in the first position, and displaceable relative to the adjacent part between a protruding position protruding from the adjacent part and a stored position being stored in the adjacent part, and engaging with the locking device when the seat movable part is displaced to the first position while in the protruding position; and a cable to which one end of an inner wire inserted through an outer casing is connected to the movable striker, one end of a thread member is connected to the other end of the inner wire, and the other end of the thread member is connected to the seat movable part, and which displaces the movable striker from the protruding position to the stored position in conjunction with the displacement of the seat movable part from the first position to the second position, and displaces the movable striker from the stored position to the protruding position in conjunction with the displacement of the seat movable part from the second position to the first position.

[0008] In the first embodiment of the vehicle seat, a locking device is provided on a movable part of the seat that is displaceable between a first position and a second position relative to the vehicle. A movable striker is provided on an adjacent part that is positioned adjacent to the movable part of the seat when the movable part of the seat is in the first position. This movable striker is displaceable relative to the adjacent part between a protruding position where it protrudes from the adjacent part and a retracted position where it is stored in the adjacent part. When the movable part of the seat is displaced to the first position while in the protruding position, it engages with the locking device.

[0009] A cable is stretched between the movable striker and the movable part of the seat. In this cable, one end of an inner wire inserted through the outer casing is connected to the movable striker, one end of a thread member is connected to the other end of the inner wire, and the other end of the thread member is connected to the movable part of the seat. This cable displaces the movable striker from the protruding position to the retracted position in conjunction with the displacement of the movable part of the seat from the first position to the second position, and also displaces the movable striker from the retracted position to the protruding position in conjunction with the displacement of the movable part of the seat from the second position to the first position. Even if the space for routing this cable is narrow, the thread member can be bent to fit the narrow space, making cable routing easier.

[0010] A vehicle seat of the second embodiment comprises, in the first embodiment, a seat cushion on which an occupant sits, and a seat back that supports the occupant's back, wherein the seat back has an adjacent part, a back body part that constitutes the main body of the seat back, and a seat movable part that is rotatable between a first position, an upright position, and a second position, a forward-tilted position, relative to the vehicle.

[0011] In the second embodiment of the vehicle seat, the back of the occupant seated on the seat cushion is supported by the seat back. This seat back has a back body that constitutes the main body of the seat back, and a back movable part that is rotatable between an upright position and a forward-tilted position relative to the vehicle. When the back movable part is in the upright position, a locking device provided on the back movable part engages with a movable striker provided on the back body. In this embodiment, the movable striker can be displaced from the protruding position to the retracted position in conjunction with the rotation of the back movable part from the upright position to the forward-tilted position, and the movable striker can be displaced from the retracted position to the protruding position in conjunction with the rotation of the back movable part from the forward-tilted position to the upright position.

[0012] In the third embodiment of the vehicle seat, the back movable part is rotatably connected to a connecting bracket fixed to a back body frame that constitutes the skeleton of the back body, and the thread member is wrapped around a resin member attached to the connecting bracket.

[0013] In the third embodiment of the vehicle seat, a resin member is attached to a connecting bracket fixed to the back body frame, which is the skeleton of the back body. A cable thread is wound around this resin member. This allows the thread to be bent at the point where it is wound around the resin member, and also allows the thread to slide smoothly against the resin member. [Effects of the Invention]

[0014] As described above, the vehicle seat according to the present invention makes it easier to route cables even when the space for routing cables is narrow. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0016] Hereinafter, a vehicle seat 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 12. In each figure, some reference numerals may be omitted for the sake of easy viewing of the drawing. Also, the arrows FR, LH, RH, and UP appropriately shown in each figure indicate the front, left, right, and upper directions of the vehicle seat 10, respectively. Hereinafter, when simply using the directions of front, rear, left, right, up, and down for explanation, it is assumed to indicate the directions with respect to the vehicle seat 10.

[0017] As shown in FIG. 1, the vehicle seat 10 according to the present embodiment includes a seat cushion 14 on which an occupant sits, a seat back 16 that supports the occupant's back, and two headrests 18 that support the occupant's head. This vehicle seat 10 is a two-seater seat and constitutes the right side portion and the left-right center portion of a three-seater rear seat. On the left side of this vehicle seat 10, there is a configuration in which a single-seater vehicle seat (not shown) is arranged.

[0018] The seat back 16 comprises a back body portion 20 that constitutes the main body of the seat back 16, and a back movable portion 22 arranged alongside the back body portion 20 on one side in the seat width direction (in this case, the left side). The lower central part 20A of the back, which is part of the back body portion 20, protrudes to the left from the lower part of the back body portion 20 and is located below the back movable portion 22. The back movable portion 22 is rotatable relative to the back body portion 20 (i.e., relative to the vehicle) between the upright position shown in Figure 1 and the tilted position where it is tilted forward onto the seat cushion 14 (see Figure 9). This back movable portion 22 can be used as an armrest in the tilted position. The back body portion 20 corresponds to the "adjacent portion" in this invention, and the back movable portion 22 corresponds to the "seat movable portion" in this invention.

[0019] As shown in Figure 2, the frame 12 that constitutes the skeleton of the vehicle seat 10 includes a cushion frame 24 that constitutes the skeleton of the seat cushion 14, a back body frame 26 that constitutes the skeleton of the back body 20, and a back movable frame 34 that constitutes the skeleton of the back movable part 22.

[0020] The cushion frame 24 is constructed from, for example, metal pipes or metal plates, and has a roughly frame-like shape with the left-right direction as the longitudinal direction when viewed from above. Similarly, the back body frame 26 is constructed from, for example, metal pipes or metal plates, and has a roughly frame-like shape with the up-down direction as the longitudinal direction when viewed from behind. Similarly, the back movable frame 34 is constructed from, for example, metal pipes or metal plates, and has a roughly frame-like shape with the up-down direction as the longitudinal direction when viewed from behind.

[0021] Three hinge brackets 36, 38, and 40 are fixed to the rear of the cushion frame 24. The three hinge brackets 36, 38, and 40 are spaced apart in the left-right direction and extend upward from the rear of the cushion frame 24. Hinge bracket 36 is fixed to the right end of the rear of the cushion frame 24, hinge bracket 38 is fixed to the middle of the rear of the cushion frame 24 in the left-right direction, and hinge bracket 40 is fixed to the left end of the rear of the cushion frame 24.

[0022] The lower end of the back frame 26 is positioned between the hinge bracket 36 and the hinge bracket 38. The back frame 26 is connected to the hinge brackets 36 and 38 via a well-known reclining mechanism 44. Slightly below the vertical midpoint of the back frame 26, an intermediate frame 28 is provided that extends in the left-right direction. The intermediate frame 28 is made of, for example, a metal pipe and has an extension 28A that extends to the left side of the back frame 26.

[0023] A connecting bracket 42, which is constructed by joining two metal plates, is fixed to the left end of the extension 28A of the intermediate frame 28 by means of welding or other means. The connecting bracket 42 extends downward from the left end of the extension 28A. The lower end of the connecting bracket 42 is superimposed on the upper end of the hinge bracket 40 from the right side and is connected to the upper end of the hinge bracket 40 using a stepped bolt 46 and a nut (not shown). The stepped bolt 46 is arranged coaxially with the reclining mechanism 44 described above. When the lock of this reclining mechanism 44 is released, the back body frame 26, i.e., the back body 20, tilts in the front-rear direction relative to the cushion frame 24, i.e., the seat cushion 14. At this time, the connecting bracket 42 is configured to tilt integrally with the back body frame 26.

[0024] A connecting bracket 48 is provided at the right end of the extension 28A of the intermediate frame 28, paired with the connecting bracket 42. The connecting bracket 48 is made of, for example, a metal plate and is fixed to the right end of the extension 28A by means of welding or other means, and extends diagonally downward and forward from the extension 28A. Corresponding to this connecting bracket 48, a connecting portion 42A extending forward is provided at the upper end of the connecting bracket 42. As shown in Figures 2 and 3, the lower end of the back movable frame 34 is positioned between the connecting portion 42A of the connecting bracket 42 and the connecting bracket 48.

[0025] The back movable section 22, whose skeleton is formed by the back movable frame 34 described above, has a pad 50 (see Figure 1), which is a cushioning material that covers the back movable frame 34, and a trim cover 54 (see Figure 1), which is a surface material that covers the pad 50. The pad 50 is made of a foam, such as urethane foam. The trim cover 54 is formed into a bag shape by sewing together multiple surface pieces made of, for example, cloth, leather, or synthetic leather.

[0026] When the back movable part 22 is in the upright position, a pair of left and right rotating shafts 70 are provided at the lower end of the back movable frame 34 (hereinafter simply referred to as "the lower end of the back movable frame 34"). The left and right rotating shafts 70 are arranged coaxially with the left and right direction as the axial direction. The back movable frame 34 is rotatably connected to the connecting part 42A and the connecting bracket 48 of the connecting bracket 42 via the left and right rotating shafts 70. As a result, the back movable frame 34 (i.e., the back movable part 22) is rotatable around the left and right rotating shafts 70 relative to the back main frame 26 (i.e., the back main body part 20).

[0027] Furthermore, a stopper pin 72 is fixed to the lower end of the back movable frame 34. The stopper pin 72 is made of, for example, a round metal bar and is positioned with its left-right direction as its axis. Both axial ends of the stopper pin 72 protrude from the back movable part 22 in the left-right direction, and these protruding parts engage with the connecting part 42A and the connecting bracket 48 of the connecting bracket 42, thereby limiting the rotation range of the back movable part 22 to between the upright position and the forward-tilted position.

[0028] As shown in Figures 2 and 3, a locking device 74 is fixed to the upper part of the back movable frame 34. This locking device 74 corresponds to the movable striker 78 shown in Figures 2 to 5. The movable striker 78 has a fixed bracket 80 fixed to the upper left side of the back main frame 26, and a striker body 82 that is rotatably mounted to the fixed bracket 80.

[0029] The fixing bracket 80 is made of, for example, a press-formed metal plate and has a front wall 80A and a rear wall 80B that face each other in the front-rear direction, and a connecting wall 80C that connects the lower left ends of the front wall 80A and the rear wall 80B in the front-rear direction. This fixing bracket is fixed to the back movable frame 34 by means of, for example, welding.

[0030] The striker body 82 is composed of a bracket connecting portion 82A made of, for example, a press-formed metal plate, and a striker portion 82B made of, for example, a bent metal round bar. The striker portion 82B is roughly U-shaped and is fixed to the bracket connecting portion 82A by means of welding or other means. The bracket connecting portion 82A is connected to the fixed bracket 80 via a connecting shaft 84 that penetrates the front wall 80A and rear wall 80B of the fixed bracket 80 and the bracket connecting portion 82A. The connecting shaft 84 is positioned with its axis in roughly the front-rear direction, and the striker body 82 is rotatable around the connecting shaft 84 relative to the fixed bracket 80.

[0031] The striker body 82 described above is rotatable relative to the fixed bracket 80 between the protruding position shown in Figures 2 to 4 and the retracted position shown in Figure 5. When the striker body 82 is in the retracted position, it is stored inside the back body 20. When the striker body 82 is in the protruding position, the striker portion 82B of the striker body 82 protrudes to the left from the left side of the back body 20. The striker body 82 is biased to the protruding position by a tension coil spring 86, which is a biasing member stretched between it and the fixed bracket 80.

[0032] When the striker body 82 is in the protruding position and the back movable part 22 rotates from the forward tilted position to the upright position, a latch (not shown) provided on the locking device 74 of the back movable part 22 catches on the striker part 82B. This is configured to restrain (lock) the back movable part 22 in the upright position. A strap (not shown) is connected to the locking device 74, and when this strap is pulled, the latch catches on the striker part 82B.

[0033] As shown in Figures 4 and 5, a locking portion 81 is provided at the lower end of the front wall 80A of the fixed bracket 80, to which one end of the outer casing 92 of the cable 90 is locked. As shown in Figures 2 and 3, this cable 90 is stretched between the movable striker 78 and the back movable part 22. One end of the inner wire 94 of this cable 90 is locked (connected) to a locking portion 83 (see Figures 4 and 5) provided on the bracket connecting portion 82A of the striker body 82. This locking portion 83 is a part of the bracket connecting portion 82A that extends forward from the front wall 80A of the fixed bracket 80.

[0034] The cable 90 described above extends downward from the movable striker 78 within the bag body 20, and bends to the left slightly below the intermediate frame 28, and is routed into the lower central part 20A of the bag, which is part of the bag body 20. The outer casing 92 of the cable 90 and the other end of the inner wire 94 are located within the lower central part 20A of the bag.

[0035] The other end of the outer casing 92 is secured to a waist support portion 96, which forms part of the back body frame 26, via a mounting plate 97 and a mounting bracket 98. The waist support portion 96 is formed, for example, by bending a round metal bar. This waist support portion 96 is fixed to a back plate 30 (see Figures 6 and 7), which also forms part of the back body frame 26. The back plate 30 is made, for example, of a press-formed metal plate, and is a long plate with its longitudinal direction in the left-right direction and its thickness direction in the front-back direction, extending to the left from the left end of the back body frame 26. The left end of the back plate 30 is fixed to the upper part of the connecting bracket 42 by means of welding or other means.

[0036] The lumbar support portion 96 is roughly U-shaped when viewed in the front-to-back direction. The upper end of the lumbar support portion 96 is fixed to the back plate 30 by means of welding or other means. The lower end of the lumbar support portion 96 is bent forward and is configured to support the lumbar region (sacrum) of the occupant seated on the seat cushion 14 from the rear.

[0037] The mounting plate 97 is made of, for example, a metal plate and has a long plate shape with the left-right direction as the longitudinal direction and the front-back direction as the thickness direction. This mounting plate 97 is superimposed on the lower part of the waist support 96 from the rear side and is fixed to the waist support 96 by means of welding or other means. The mounting bracket 98 is made of, for example, a metal plate bent into an L shape. This mounting bracket 98 is superimposed on the middle part of the front surface of the mounting plate 97 in the left-right direction from the front side and is fixed to the mounting plate 97 by means of welding or other means. The other end of the outer casing 92 is locked to this mounting bracket 98.

[0038] The other end of the inner wire 94 protrudes to the left from the other end of the outer casing 92. A cable end 94A is provided at the other end of the inner wire 94. Near the right side of the cable end 94A, one end of a thread member 100 is attached to the inner wire 94. The thread member 100 is made of a chemically synthesized fiber such as nylon or polyester, and is constructed to have high tensile strength and abrasion resistance. This thread member 100 is tied to the other end of the inner wire 94 by, for example, a complete knot (fishing knot).

[0039] As shown in Figures 6 to 12, a resin bush 102 is attached to the lower part of the connecting bracket 42, corresponding to the thread member 100. The resin bush 102 corresponds to the "resin member" in this invention. This resin bush 102 is manufactured, for example, by resin injection molding and is formed in a cylindrical shape with a flange. This resin bush 102 is fitted from the left side into a circular through hole 104 (see Figure 12) formed in the lower part of the connecting bracket 42, and is positioned with the flange facing to the left. The middle part of the thread member 100 is inserted inside this resin bush 102.

[0040] The middle portion of the thread member 100, which is inserted inside the resin bush 102, is wrapped around the resin bush 102 and bent upward. The other end of the thread member 100 is locked (connected) to the left end of the stopper pin 72 via a lever 106. The lever 106 is made of, for example, a metal plate and has a roughly teardrop shape. This lever 106 is fixed to the left end of the stopper pin 72 by means of welding or other means and has a projection 106A that protrudes radially from the rotation axis 70. A circular through hole 108 is formed at the tip of this projection 106A, and the other end of the thread member 100 is inserted through this through hole 108. The other end of the thread member 100 is tied to the tip of the projection 106A, for example, by a complete knot.

[0041] As shown in Figure 8, when the back movable part 22 is in the upright position, the protruding part 106A of the lever 106 is positioned diagonally downward and rear of the stopper pin 72. In this state, the striker body 82 of the movable striker 78 is positioned in the protruding position shown in Figures 2 to 4. When the back movable part 22 rotates from the upright position to the forward-tilted position shown in Figure 9, the protruding part 106A of the lever 106 rotates diagonally upward and rear of the stopper pin 72. As a result, the other end of the thread member 100, which is locked to the protruding part 106A of the lever 106, is pulled upward. At this time, the middle part of the thread member 100 slides with the resin bush 102, and one end of the thread member 100 is displaced to the left. As a result, the other end of the inner wire 94, which is locked to one end of the thread member 100, is pulled out by a predetermined amount to the left from the other end of the outer casing 92. As a result, one end of the inner wire 94, which is locked to the striker body 82 of the movable striker 78, is pulled downward, and the striker body 82 rotates from the protruding position to the retracted position shown in Figure 5. This ensures that when the back movable part 22 is used as an armrest, the striker part 82B of the striker body 82 is retracted into the back body part 20.

[0042] Furthermore, when the back movable part 22 rotates from the forward-tilted position shown in Figure 9 to the upright position shown in Figure 8, the protruding part 106A of the lever 106 rotates diagonally downward and rearward of the stopper pin 72, causing the other end of the inner wire 94 to be pulled in by a predetermined amount toward the other end of the outer casing 92. As a result, one end of the inner wire 94, which is locked to the striker body 82 of the movable striker 78, is pulled upward, and the striker body 82 rotates from the stored position shown in Figure 5 to the protruding position shown in Figures 2 to 4. As a result, the latch 76 of the locking device 74 of the back movable part 22, which is rotating to the upright position, catches on the striker part 82B, and the back movable part 22 is locked in the upright position. Note that when the striker body 82 rotates to the protruding position as described above, the rotation of the striker body 82 to the protruding position is assisted by the tension coil spring 86 of the movable striker 78.

[0043] In the vehicle seat 10 with the above configuration, the back of the occupant seated on the seat cushion 14 is supported by the seat back 16. This seat back 16 comprises a back body 20 that constitutes its main body, and a back movable part 22 that is rotatable between an upright position and a forward-tilted position relative to the back body 20. The back movable part 22 can be used as an armrest when it is in the forward-tilted position.

[0044] A locking device 74 is provided on the back movable part 22, and a movable striker 78 is provided on the back body part 20. The striker body 82 of the movable striker 78 is rotatable relative to the back body part 20 between a protruding position where it protrudes from the back body part 20 and a retracted position where it is stored in the back body part 20. When the back movable part 22 rotates to the upright position while the striker body 82 is in the protruding position, the locking device 74 engages with the striker body 82.

[0045] A cable 90 having an outer casing 92 and an inner wire 94 is stretched between the back movable part 22 and the movable striker 78. In this cable 90, one end of a thread member 100 is connected to the other end of the inner wire 94 which is inserted through the outer casing 92. One end of the inner wire 94 is connected to the striker body 82 of the movable striker 78, and the other end of the thread member 100 is connected to the back movable part 22. This cable 90 displaces the striker body 82 from the protruding position to the retracted position in conjunction with the rotation of the back movable part 22 from the upright position to the forward-tilted position, and also displaces the striker body 82 from the retracted position to the protruding position in conjunction with the displacement of the back movable part 22 from the forward-tilted position to the upright position. Thus, according to this embodiment, the striker body 82 of the movable striker 78 can be displaced in conjunction with the rotation of the back movable part 22.

[0046] Furthermore, as in this embodiment, even when the cable routing space for the cable 90 within the lower center 20A of the bag is narrow, the thread member 100 can be bent to fit the narrow space, making it easier to route the cable 90. In addition, in this embodiment, the movable part of the bag 22 is rotatably connected to a connecting bracket 42 fixed to the bag body frame 26 which constitutes the skeleton of the bag body 20, and the thread member 100 is wrapped around a resin bush 102 attached to the connecting bracket 42. This allows the thread member 100 to be bent at the portion wrapped around the resin bush 102, and also allows for smooth sliding of the thread member 100 against the resin bush 102.

[0047] Furthermore, as shown in the modified example in Figure 13, a rotatable roller 110 may be attached to the resin bush 102, and the middle portion of the thread member 100 may be wrapped around the roller 110. This allows the thread member 100 to be displaced even more smoothly.

[0048] Furthermore, in the above embodiment, the movable back portion 22 is arranged in line with the seat width direction relative to the back body portion 20, but this is not the only configuration. For example, the movable back portion may be fitted into a recess formed on the front surface of the back body portion.

[0049] Furthermore, although the above embodiment described a case in which the vehicle seat 10 constitutes the right portion and the left-right central portion of a three-seater rear seat, it is not limited to this. When the vehicle seat 10 according to the present invention constitutes the left portion and the left-right central portion of a three-seater rear seat, the configuration is symmetrical to that of the above embodiment.

[0050] Furthermore, although the above embodiment describes a case where the back body portion 20 corresponds to the "adjacent portion" in the present invention and the back movable portion 22 corresponds to the "seat movable portion" in the present invention, the invention is not limited to this. For example, the seat back of a vehicle seat that can tilt forward and backward relative to the vehicle may correspond to the "seat movable portion" in the present invention, and the side portion of the vehicle body located to the side of the seat back may correspond to the "adjacent portion" in the present invention.

[0051] Furthermore, although the above embodiment described the case in which the present invention is applied to a vehicle seat 10, 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).
