Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above prior art, when the second seat back is used as an armrest, the striker is stored, and when the second seat back is erected, it is preferable that the striker returns to the locked position.

[0005] An object of the present invention is to obtain a vehicle seat capable of displacing a striker that engages with a lock device provided on a seat movable part that is displaced with respect to a vehicle in conjunction with the displacement of the seat movable part.

Means for Solving the Problems

[0006] 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 retracted 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 having an outer casing and an inner wire, which is stretched between the seat movable part and the movable striker, and which displaces the movable striker from the protruding position to the retracted 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 retracted position to the protruding position in conjunction with the displacement of the seat movable part from the second position to the first position, and in which the end of the inner wire bends on the seat movable part side when the seat movable part is in the first position.

[0007] 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. A cable having an outer casing and an inner wire is stretched between the movable striker and 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. Thus, according to this embodiment, the movable striker can be displaced in conjunction with the displacement of the movable part of the seat.

[0008] Furthermore, when the seat's movable part is in the first position, the end of the inner wire flexes on the seat's movable part side. As a result, when displacing the seat's movable part from the first position to the second position, the movable striker can be displaced from the protruding position to the retracted position with a delay compared to the displacement of the seat's movable part. Also, when displacing the seat's movable part from the second position to the first position, the movable striker can be displaced from the retracted position to the protruding position in advance, before the seat's movable part reaches the first position.

[0009] 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.

[0010] 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.

[0011] In the third embodiment of the vehicle seat, in the second embodiment, the movable back portion has a pivot shaft that is rotatably supported on a connecting bracket fixed to the back body frame which constitutes the skeleton of the back body portion, the outer casing has its end locked to the connecting bracket, and the inner wire has its end locked to a rotating member which is provided to be rotatable integrally with the pivot shaft.

[0012] In the third embodiment of the vehicle seat, a connecting bracket is fixed to the back body frame, which is the skeleton of the back body. The rotation axis of the back movable part is rotatably supported on this connecting bracket, and the end of the cable's outer casing is locked to it. The end of the cable's inner wire is locked to a rotating member that is provided to rotate integrally with the rotation axis of the back movable part. With this configuration, the setting for bending the end of the inner wire when the back movable part is in the upright position can be made with reference to the connecting bracket, making this setting easier. [Effects of the Invention]

[0013] As described above, according to the vehicle seat of the present invention, the striker that engages with a locking device provided on the movable part of the seat that is displaced relative to the vehicle can be displaced in conjunction with the displacement of the movable part of the seat.

Mode for Carrying Out the Invention

[0015] Hereinafter, a vehicle seat 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 9. In each figure, some reference numerals may be omitted for the sake of clarity of the drawing. Also, the arrows FR, LH, and UP appropriately shown in each figure indicate the front, left, and upper directions of the vehicle seat 10, respectively. Hereinafter, when simply describing the directions of front, rear, left, right, up, and down, it is assumed that the directions with respect to the vehicle seat 10 are indicated.

[0016] As shown in FIG. 1, the vehicle seat 10 according to the present embodiment includes a seat cushion 14 on which a passenger sits, a seat back 16 that supports the back of the passenger, and two headrests 18 that support the head of the passenger. 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. A single-seater vehicle seat (not shown) is arranged to the left of this vehicle seat 10.

[0017] The seat back 16 includes a back main body portion 20 that constitutes the main body of the seat back 16, and a back movable portion 22 arranged side by side with respect to the back main body portion 20 on one side in the seat width direction (here, the left side). A back central lower portion 20A, which is a part of the back main body portion 20, protrudes from the lower portion of the back main body portion 20 to the left side and is disposed below the back movable portion 22. The back movable portion 22 is rotatable with respect to the back main body portion 20 (that is, with respect to the vehicle) between the upright position shown in FIG. 1 and the forward-falling forward-fall position (see FIG. 13). This back movable portion 22 can be used as an armrest in the forward-fall position. The back main 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.

[0018] As shown in FIG. 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 main body frame 26 that constitutes the skeleton of the back main body portion 20, and a back movable frame 34 that constitutes the skeleton of the back movable portion 22.

[0019] The cushion frame 24 is constituted by, for example, a metal pipe material, a metal plate material, etc., and has a substantially frame shape with the left-right direction as the longitudinal direction when viewed in the up-down direction. Similarly, the back main body frame 26 is constituted by, for example, a metal pipe material, a metal plate material, etc., and has a substantially frame shape with the up-down direction as the longitudinal direction when viewed in the front-rear direction. Similarly, the back movable frame 34 is constituted by, for example, a metal pipe material, a metal plate material, etc., and has a substantially frame shape with the up-down direction as the longitudinal direction when viewed in the front-rear direction.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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).

[0026] 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.

[0027] As shown in Figure 2, 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, 3, and 4. 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.

[0028] 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.

[0029] 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.

[0030] The striker body 82 described above is rotatable relative to the fixed bracket 80 between the protruding position shown in Figures 2 and 3 and the retracted position shown in Figure 4. 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.

[0031] 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.

[0032] As shown in Figures 3 and 4, 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 Figure 2, 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 to a locking portion 83 (see Figures 3 and 4) provided on the bracket connecting portion 82A of the striker body 82. This locking portion 81 is a part of the bracket connecting portion 82A that extends forward from the front wall 80A of the fixed bracket 80.

[0033] 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 within the lower central part 20A of the bag, which is part of the bag body 20. The other ends of the outer casing 92 and inner wire 94 of this cable 90 extend from the left end of the lower central part 20A of the bag to the outside of the lower central part 20A of the bag. The other end of the outer casing 92 corresponds to the "end of the outer casing" in this invention, and the other end of the inner wire 94 corresponds to the "end of the inner wire" in this invention.

[0034] The other end of the outer casing 92 is locked to a locking portion 43 provided on the upper part of the connecting bracket 42. This locking portion 43 is formed, for example, by cutting and bending a part of the upper part of the connecting bracket 42. The other end of the inner wire extends upward from the other end of the outer casing 92 and is locked to a lever 96 that is provided to rotate integrally with the back movable portion 20. This lever 96 corresponds to the "rotating member" in this invention.

[0035] The lever 96 described above is made of, for example, a metal plate and has a roughly teardrop shape. This lever 96 is rotatable integrally with the rotation axis 70 of the back movable part 22 and has a projection 96A that protrudes radially from the rotation axis 70. A circular through hole (reference numeral omitted) is formed at the tip of this projection 96A, and the cable end 94A provided at the other end of the inner wire 94 is fitted into the through hole. In this way, the other end of the inner wire 94 is locked to the lever 96.

[0036] As shown in Figure 6, when the back movable part 22 is in the upright position, the protruding part 96A of the lever 96 is positioned diagonally downward and rearward of the rotation axis 70. In this state, as shown in Figures 5 and 6, the other end of the inner wire 94 bends diagonally upward and rearward, and the striker body 82 of the movable striker 78 is positioned in the protruding position.

[0037] When the back movable part 22 rotates from the upright position to the forward-tilted position, the lever 96 rotates together with the rotation axis 70 of the back movable part 22. Then, as shown in Figure 7, when the back movable part 22 rotates a predetermined angle (for example, 80 degrees) from the upright position to the forward-tilted position, the protruding part 96A of the lever 96 is positioned behind the rotation axis 70. In this state, the deflection of the other end of the inner wire 94 is eliminated, and the other end of the inner wire 94 becomes straight. When the back movable part 22 rotates further towards the forward-tilted position than this state, the other end of the inner wire 94 is pulled out by a predetermined amount 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 is configured to rotate from the protruding position to the retracted position.

[0038] As shown in Figure 8, when the movable back section 22 reaches the forward-tilted position, the protruding portion 96A of the lever 96 is positioned diagonally upward and rearward with respect to the rotation axis 70. In this state, the striker body 82 of the movable striker 78 is positioned in the retracted position. This configuration ensures that when the movable back section 22 is used as an armrest, the striker body 82 is stored inside the back body section 20.

[0039] On the other hand, when the back movable part 22 rotates from the tilted position to the upright position, the lever 96 rotates together with the rotation axis 70 of the back movable part 22. Then, as shown in Figure 9, when the back movable part 22 rotates by a predetermined angle (for example, 80 degrees) from the tilted position to the upright position, the protruding part 96A of the lever 96 is positioned diagonally downward and rearward of the rotation axis 70, and the other end of the inner wire 94 is 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 is configured to rotate from the stowed position to the protruding position.

[0040] When the back movable part 22 reaches the upright position, the latch of the locking device 74 of the back movable part 22 catches on the striker part 82B, and the back movable part 22 is locked in the upright position. 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.

[0041] 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.

[0042] 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.

[0043] 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. 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. In addition, this cable 90 displaces the movable striker 78 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.

[0044] Furthermore, when the back movable part 22 is in the upright position, the other end of the inner wire 94 bends. As a result, when displacing the back movable part 22 from the upright position to the forward-tilted position, the striker body 82 can be displaced from the protruding position to the retracted position with a delay in the rotation of the back movable part 22. Also, when rotating the back movable part 22 from the forward-tilted position to the upright position, the striker body 82 can be displaced from the retracted position to the protruding position in advance before the back movable part 22 reaches the upright position.

[0045] Furthermore, in this embodiment, a connecting bracket 42 is fixed to the back body frame 26, which constitutes the skeleton of the back body portion 20. The rotation axis 70 of the back movable portion 22 is rotatably supported on this connecting bracket 42, and the other end of the outer casing 92 of the cable 90 is locked to it. The other end of the inner wire 94 of the cable 90 is locked to a lever 96 which is provided to rotate integrally with the rotation axis 70 of the back movable portion 22. With this configuration, the setting for bending the other end of the inner wire 94 when the back movable portion 22 is in the upright position can be made with reference to the connecting bracket 42, making the setting easier.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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).

[0050] 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]
