[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle seat device in which a child seat is provided in a seat back portion so that the child seat can be stored and taken out.

[0002]

[Prior art]

 In recent years, in a vehicle seat device, a seat back portion of a fixed rear seat is provided with a child seat that is stored on the seat back side when not in use and is taken out from the seat back to the seat cushion side when used. It has been attempted to provide a seat belt for a child seat in a state of being fixed to a seat back (see, for example, Japanese Utility Model Publication No. 54-17924 and Japanese Utility Model Publication No. 54-17925).

[0003]

[Problems to be solved by the device]

 By the way, when the seat back is fixed as in this known example, the load applied to the seat belt is always directly supported by the vehicle body through the seat back, and therefore the use of the child seat is restricted depending on the state of the seat back. The child seat can be used at any time, if desired.

However, when the seat back in which the child seat is incorporated is foldable, the use of the child seat is limited depending on whether the seat back is fixed to the vehicle body side by the seat lock device. That is, in the case of a retractable seat back, the seat back is fixed to or released from the vehicle body by a seat lock device, and the seat belt for a child seat is fixed to this retractable seat back side. It is necessary to. Therefore, the load applied to the seat belt is supported from the seat back to the vehicle body side through the seat lock device. Therefore, it is necessary to prevent the use of the child seat when the seat lock device is in the lock-off state and prevent the lock-off operation of the seat lock device when the child seat is in the in-use state.

However, as far as the inventor of the present invention knows, there is no retractable seat back in which a child seat is incorporated. Therefore, naturally, in a vehicle seat device including such a retractable seat back, No useful proposal has been made regarding means for ensuring safety in use.

Therefore, the present invention has been made for the purpose of ensuring the safety in use of the child seat in a vehicle seat device including a retractable seat back incorporating a child seat.

[0007]

[Means for Solving the Problems]

 In the present invention, as a specific means for solving such a problem, a seat that can be erected between a substantially upright position in use and a laid position in which the vehicle is tilted toward the front side of the vehicle from the position in use. A child seat is attached to the front surface of the back via a rotary shaft, and the child seat is disposed between a storage position where the child seat is buried and stored in the seat back side and a use position where the child seat is taken out from the seat back and placed on a seat cushion. The seat back is engaged with a striker fixed to the vehicle body side so that the seat back is fixed to the vehicle body side in the use position and the striker is engaged. And a seat lock device provided with a striker hook that operates between a lock-off state that allows the seat back to be tilted, In addition, in a vehicle seat device in which a seat belt for a child seat is fixed to the seat back side, a first position and a lock off position which are provided on the seat lock device side and can engage with the striker hook in the lock-on state. The striker hook is in a state where it can be displaced between a second position where it can be engaged, and in the state where the first position is set, displacement of the striker hook to the lock-off side is restricted and the first position is set. Displacement from the second position to the second position is allowed, and when the second position is set, the striker hook is allowed to move toward the lock-on side and the second position moves toward the first position. A regulation member configured to be regulated, and provided between the regulation member and the rotation shaft of the child seat, The rolling displacement can be transmitted to the restriction member, and the restriction member is set to the second position when the child seat is set to the storage position, and the restriction member is set to the second position when the child seat is set to the in-use position. And a linking member that can be set to the first position.

[0008]

[Action]

 According to the present invention, by adopting such a configuration, in the state where the striker hook of the seat lock device is in the lock-on state and the seat back is securely fixed to the vehicle body side, the restricting member is located at the first position and the first position. Since it can be freely displaced between the two positions, it is possible to tilt the child seat around its rotation axis to set it in the storage position or the in-use position.

Further, when the child seat is set to the in-use position in the lock-on state of the striker hook, the restricting member receives the rotational displacement of the linking member to be set to the first position and the posture thereof is maintained. It Therefore, the striker hook is restricted from being displaced toward the lock-off side by the engagement with the restriction member set to the first position, and is held in the lock-on state.

Further, when the striker hook is in the lock-off state and the seat back is not fixed to the vehicle body side, the restricting member is displaced from the second position to the first position side by engagement with the striker hook. Since the rotation of the rotary shaft is regulated by the linking member, no matter how the child seat is taken out from the storage position to the use position, the rotation of the rotary shaft is surely prevented.

[0011]

[Effect of device]

 Therefore, according to the vehicle seat device of the present invention, the seat back is securely fixed to the vehicle body side by the seat locking device by actuating the restricting member according to the state of the child seat through the linking member. The child seat can be used only in such cases, but when the child seat is used, the lock-off of the seat lock device is prevented and the seat back is reliably prevented from being disengaged from the vehicle body. The seat belt load is reliably supported during use, and high safety is ensured during use of the child seat despite the structure in which the child seat is provided on the retractable seat back.

As shown by the solid line in FIG. 4, the seat lock device 50 has the striker hook 61 in a state where the rotation of the striker hook 61 in the direction of the arrow a is restricted by the first stopper claw 62. The striker receiving groove 61a of the catch bracket 60 holds the striker 54 fixed on the vehicle body in the space surrounded by the stopper surface 56 of the catch bracket 60 (that is, the seat lock device 50 is locked). It is in the on state, and in the following, the position of the striker hook 61 in this case is called the catch position). On the other hand, when the operation button 57 is pressed to release the engagement between the first stopper claw 62 and the striker hook 61, the striker hook 61 causes the spring force of the spring 65 as shown by the chain line in FIG. Is rotated in the direction of arrow a to open the striker receiving groove 61a to the seat back side, and the striker 54 can be inserted and removed (that is, the seat lock device 50 is in the lock-off state, Hereinafter, the position of the striker hook 61 in this case will be referred to as a release position). The rotation of the striker hook 61 in the direction of the arrow a is restricted by the second engaging portion 61c of the striker hook 61 abuttingly engaging with the stopper portion 58 of the catch bracket 60.

On the other hand, on the other end side of the catch bracket 60, a guide plate 70 is formed by bending and extending the end portion of one plate body 60 A in the thickness direction of the striker hook 61. . A restricting member 45 described later is attached to the guide plate 70 so as to be slidably displaced along guide pins 69, 69 provided on the guide plate 70. As shown in FIG. 6, the restricting member 45 includes a pillar portion 45c having a predetermined length in which a guide groove 45e having a predetermined length in which the guide pins 69, 69 are loosely fitted is formed and an upper end of the pillar portion 45c.

As shown in FIGS. 4 and 5, the restricting member 45 has the striker hook 61 in a state in which the first engaging element 45a is located near the arrow a direction with respect to the guide plate 70. Is slidably displaced in the thickness direction (direction of arrow c-d), and is always attached in the direction of arrow c by a spring 66 mounted between the other plate body 60B and the spring mounting portion 45f. It is energized. Further, the position of the restricting member 45 in the direction of arrow c is restricted by the engagement of the guide pin 69 with the end of the guide groove 45e, but its upper moving position (hereinafter referred to as the second position). 4, the pair of engaging elements 45a and 45b both project above the striker hook 61 to allow the striker hook 61 to rotate in the direction of arrow ab as shown in solid lines in FIGS. I'm supposed to get it. On the other hand, in the downward movement position (hereinafter referred to as the first position) in which the restricting member 45 is forcibly pulled downward (in the direction of arrow d) by the push-bull cable 25 described later, FIG. As shown by the chain line, the pair of engagement elements 45a and 45b are both positioned so as to overlap the striker hook 61 in the upward and downward directions.

Further, the relative position in the plane direction of the striker hook 61 between the pair of engagement elements 45a, 45b of the regulation member 45 and the third engagement portion 61d of the striker hook 61 is as follows. Is set. That is, as shown by the solid line in FIG. 4, when the striker hook 61 is in the lock-on state, the short second engaging element 45b closely faces the third engaging portion 61d, and is also shown by a chain line in the same figure. As described above, when the striker hook 61 is in the lock-off state, the elongated first engaging element 45a is set so as to overlap with the striker hook 61.

Therefore, when the restricting member 45 is set to the first position as shown by the chain line in FIG. 5, the second engaging element 45 b of the restricting member 45 and the third engaging portion of the striker hook 61. When the striker hook 61 is brought into contact with the striker hook 61, the displacement of the striker hook 61 from the lock-on state to the lock-off state is restricted. Further, when the restricting member 45 is set to the second position as shown by the solid line in FIG. 4, the respective engaging elements 45a, 45b of the restricting member 45 and the striker hook 61 are vertically displaced. Therefore, the striker hook 61 can be freely set to either the lock-off state or the lock-on state. However, when the striker hook 61 is set to the lock-off state, the first engaging element 45a of the restricting member 45 and the striker hook 61 overlap in the vertical direction. When moving from the second position to the first position, both of them engage with each other and are blocked.

In order to restrict the operation of the seat lock device 50 by the restricting member 45 in accordance with the operation state of the child seat 4, the restricting member 45 and the rotary shaft 21 of the child seat 4 are interposed. Further, a linking member 48 as described later is provided. As shown in FIG. 6, the linking member 48 includes the rotating shaft 21, which connects the bracket 20 of the backrest plate 16 and the bracket 17a of the booster plate 17, the rotating shaft 21, and the regulating member 45. And a push-bull cable 25 that connects the two.

That is, the rotary shaft 21 has a screw portion 21a having a chamfered portion and a rod-shaped portion 21b extending coaxially with the screw portion 21a, and the rod-shaped portion 21b has a projecting piece shape. A cable mounting portion 21c is provided. The rotary shaft 21 has a round hole-shaped shaft hole 20a in which the screw portion 21a is formed in the bracket 20 of the backrest plate 16 and a square slide portion provided in the bracket 17a of the booster plate 17. It is fixed by being inserted into the hole booster plate 17b. Further, one end 25a of the pushable cable 25 is connected to the cable mounting portion 21c of the rotary shaft 21, and the other end 25b of the pushable cable 25 is connected to the cable mounting portion 45d of the regulating member 45. ing. Therefore, when the child seat 4 rotates in the direction of arrow CD to move the child seat 4 between the in-use position and the storage position, the rotational displacement of the child seat 4 causes the rotary shaft 21 to move toward the arrow e-. The rotational displacement of the rotary shaft 21 is transmitted to the regulating member 45 via the push-bull cable 25 as vertical displacement (direction of arrow c-d), and the rotational displacement of the rotating shaft 21 is transmitted to the regulating member 45. Is set to the second position by being displaced in the direction of arrow c when the child seat 4 is rotated in the direction of arrow D and set to the retracted position, and conversely, the child seat 4 is rotated in the direction of arrow C. Then, in the state of being set to the in-use position, the regulating member 45 is displaced in the direction of the arrow d and is set to the first position.

As described above, the rotary shaft 21 of the child seat 4 and the restricting member 45 are connected to each other via the connecting member, and the restricting member 45 is operated to operate the seat lock device 50 to operate the child seat 4. When controlled in conjunction with, the following operational effects will be obtained. That is, when the seat lock device 50 is in the lock-on state and the first retractable seat back 31 is fixed to the vehicle body side, both the engagement elements 45a and 45b of the restriction member 45 are vertically striker hooked. Since it does not overlap with 61, the child seat 4 can be freely operated between the storage position and the use position. However, in this state, once the child seat 4 is set to the in-use position, the restricting member 45 is set to the first position, and the second engaging element 45b thereof faces the third engaging portion 61d of the striker hook 61. Therefore, no matter how the operation button 57 is operated to lock off the seat lock device 50, this is prevented.

Also, when the child seat 4 is set to the storage position, the lock-off operation of the seat lock device 50 is possible, but once the seat lock device 50 is locked off, it is locked on again. Unless this is done, the operation of the child seat 4 from the retracted position to the in-use position is reliably prevented by the engagement of the striker hook 61 and the first engaging element 45a of the restricting member 45.

As described above, in the embodiment, the operation of the child seat 4 from the retracted position to the in-use position is performed only when the first retractable seat back 31 is fixed to the vehicle body side by the seat lock device 50. In addition, the lock-off operation of the seat lock device 50 is surely prevented when the child seat 4 is in the in-use position, and this is always necessary when the seat belt 5 is used. This means that the first retractable seat back 31 is fixed to the vehicle body side and its supporting performance is ensured. Therefore, for example, when a collision load is applied to the seat belt 5 at the time of a collision, this collision load is Since the inclinable seat back 31 is securely transmitted to the vehicle body side through the seat back frame 10 and supported there, the seat belt The occupant restraining action by 5 is ensured, and a high level of safety is secured even though the child seat 4 is assembled to the first retractable seat back 31. .

Second Embodiment FIG. 7 shows a seat lock device 50 portion of a vehicle seat device according to a second embodiment of the present invention. Similar to the first embodiment, this embodiment also ensures that when the child seat 4 is set to the in-use position, the seat lock device 50 ensures that the first retractable seat back 31 is placed on the vehicle body side. It is intended to secure the seat belt 5 by fixing it, and is basically based on the same idea as that of the first embodiment. While the rotational displacement of the rotary shaft 21 of the child seat 4 is transmitted to the control member 45 as the axial displacement of the pushable cable 25, in the second embodiment, the rotary shaft of the child seat 4 is transmitted. The difference is that the rotational displacement of 21 is directly transmitted to the regulating member 46 as the rotational displacement.

That is, in this embodiment, as shown in FIG. 7, the restraint member 46 having the engaging portion 46 a is provided on the catch bracket 60 of the seat lock device 50 on substantially the same plane as the striker hook 61. As shown in FIGS. 8 and 9, the support shaft 47 and the rod-shaped portion 21b of the rotary shaft 21 are connected via a torque cable 26 as shown in FIGS. The rotational displacement of the rotary shaft 21 due to the operation of the plate 17 is directly transmitted as the rotary displacement of the support shaft 47 via the torque cable 26, and the restricting member 46 is transferred to the engaging portion 46a as shown by the solid line in FIG. A second position facing the third engaging portion 61d of the striker hook 61 in the lock-off state, and a striker in the lock-on state as shown by a chain line in the figure. The first position and facing the third engaging portion 61d of the hook 61 is obtained by selectively set obtained so that.

Also in the case of such a structure, as in the case of the first embodiment, when the seat lock device 50 is locked on and the first retractable seat back 31 is securely fixed to the vehicle body side. Allows the restraint member 46 to freely move between the first position and the second position to freely set the child seat 4 to the storage position and the use position, while the seat lock device 50 locks off. Then, the rotation of the restricting member 46 is restricted by the striker hook 61 to prevent the child seat 4 from being taken out from the storage position to the in-use position, and once the child seat 4 is set to the in-use position, the restricting member is once again set. 46 is set to the first position to lock the seat lock device 50 in the lock-on state in order to prevent the striker hook 61 from rotating toward the lock-off side. With such an action, when the child seat 4 is in the in-use position, the state in which the first retractable seat back 31 is fixed to the vehicle body side is always revealed, and the seat belt 5 is in good condition. The supportive performance is secured and the safety when using the child seat 4 is secured.
