  However, in the prior art disclosed above, in order to ascertain whether the seat body is securely engaged and locked at the use position on the vehicle body floor or the storage position below the vehicle body ceiling, the lock portion is looked into and locked. It is necessary to confirm the state, and the configuration takes time.

  The present invention has been devised as a solution to the above-described problems, and the problem to be solved by the present invention is to engage and lock the engagement at each installation position where the seat body is moved relative to the vehicle body side structure. It is to be able to easily check whether or not it is done.

In order to solve the above problems, the vehicle warning structure of the present invention takes the following means.
A first aspect of the present invention is a vehicle warning structure having a warning display unit that displays a warning as an abnormal state when a seat main body serving as a seating portion is not engaged and locked with a vehicle body side structure. The seat body is configured such that the installation position relative to the vehicle body side structure is switched between the first installation position and the second installation position by movement. The seat body is provided with a first locking device for engaging and locking the seat body at the first installation position, and a second locking device for engaging and locking the seat body at the second installation position. . In each of the locking devices, the state in which the seat body is engaged and locked at each installation position is released by operating one operating member provided on the seat body. The warning display section is provided at the setting location of the operating member. The warning display is displayed when both locking devices are released, and the warning display is displayed when either locking device is in the engagement locked state. It will be in a state that does not.

  According to the first aspect of the invention, since the warning display portion is provided at the setting position of the operation member provided for the release operation of both the lock devices, one of the lock devices is provided on the vehicle body side structure. The operator can confirm whether or not the engagement is locked by looking at the set position of the operation member. Therefore, it is possible to more easily check the warning display state as compared with a configuration in which a warning display unit is provided for each locking device or is provided at a setting location of each locking device.

  Next, according to a second aspect, in the first aspect described above, the seat body has a seat back that is a backrest linked to the ceiling of the vehicle body so as to be rotatable, and the seat back is raised upward and rotated. In the aspect, the storage position can be moved from the use position on the vehicle body floor as the first installation position to the storage position under the ceiling of the vehicle body as the second installation position. The operation member is arranged and set on the back portion of the seat back.

  According to the second aspect of the invention, since the operating member is set on the back portion of the seat back, when the seat main body is in the use position on the vehicle body floor, the operator looks from the position of standing on the vehicle rear side. And reach easily. Further, when the seat body is in the retracted position under the ceiling of the vehicle body, the operator can easily reach the eyes and hands from the inside of the vehicle. Therefore, operation of the operation member and confirmation of the warning display state can be easily performed.

  Next, according to a third aspect, in the first or second aspect described above, the operating member is hinged to the seat body and is opened and closed from a closed position by a rotational operation against the bias. It is formed as an operating lever of the type. The warning display part is formed as a warning display surface in which a warning display color such as red is attached to the exposed part that is exposed when the operation member is opened. The operating member is kept in the opened state and the warning display surface is exposed even if the opening operation is stopped because both locking devices are released by the opening operation. It is the structure which is closed when the lock device on the side is in the engagement lock state.

  According to the third aspect of the invention, the warning display unit is configured to display a warning display color such as red on the exposed portion when the operation member is opened. The warning display portion is maintained in a state where a warning display color is displayed by keeping the operating member opened when both the locking devices are in the released state. And a warning display part is switched to the state which does not display a warning, when an operation member is closed when the locking device of either one side will be in an engagement lock state. In this manner, the warning display unit can be embodied as a rational configuration in which a warning display color is added to the exposed portion of the operation member.

  Embodiments of the best mode for carrying out the present invention will be described below with reference to the drawings.

  First, the configuration of the vehicle warning structure according to the first embodiment will be described with reference to FIGS. Here, FIG. 1 shows a schematic configuration of a ceiling retractable vehicle seat to which the vehicle warning structure of the present embodiment is applied. The vehicle seat is disposed as a rearmost seat of the vehicle, and is configured so that the seat body 1 serving as a seating portion can be lifted and stored from a use position on the vehicle body floor F to a storage position below the vehicle body ceiling C. Has been.

  Here, the seat body 1 includes a seat back 2 that serves as a backrest, a seat cushion 3 that serves as a seating portion, and a headrest 4 that serves as a headrest. Specifically, the seat cushion 3 is hinged to the lower end of the seat back 2 so that the rear ends of the left and right sides of the seat cushion 3 can be rotated upside down. In the reclining device 5, when the seat cushion 3 is tilted toward the front side of the seat back 2, the lock mechanism provided therein locks and the rotational posture of the seat cushion 3 is set to the tilted rotational position. It can be locked.

  The state in which the seat cushion 3 is rotationally locked is provided by the operator P at the small first operating lever 7 provided at the lower position on the back side of the seat back 2 or at the center position on the back side. It is released by opening one of the large second operation levers 30 on the back side of the seat back 2. As a result, the seat cushion 3 is rotated around the central axis 5a of the reclining device 5 by the spring force of an urging spring (not shown) hooked between the seat back 2 and raised to the position of the front portion of the seat back 2. Raised and held.

  Here, as shown in FIG. 2, the first operating lever 7 is hingedly connected to the seat back 2 by a connecting shaft 7a. The first operating lever 7 is normally held at the closed position folded on the back surface of the seat back 2 by the spring force of the torsion spring 7c hooked between the first operating lever 7 and the seat back 2. Here, the first operating lever 7 corresponds to the operating member of the present invention.

  Then, the first operating lever 7 is operated to open clockwise in the figure against the spring force of the torsion spring 7c described above, thereby pulling a cable (not shown) connected to the first operating lever 7 through a pulling operation. Thus, the locked state of the reclining device 5 (see FIG. 1) is released. Here, as shown in FIG. 1 to FIG. 2, the first operating lever 7 has a release cable 9 a for performing an unlocking operation of a backlock device 9, which will be described later, provided on the back portion of the seat back 2, A release cable 8a for performing an unlocking operation of a ceiling locking device 8 (described later) provided at the lower end portion of the seat back 2 is connected.

  In addition, although illustration is abbreviate | omitted, the cancellation | release operation which cancels | releases the locking state of the lock state of the reclining device 5 and the locking state of the ceiling locking device 8 and the back lock device 9 is similarly applied to the second operating lever 30 as well. Cables 8a and 9a are connected to each other.

  As a result, when the first operation lever 7 and the second operation lever 30 are opened, both the release cables 8a and 9a are pulled all at once, and the unlocking operation of the back lock device 9 and the ceiling lock device 8 is performed. It is going to be performed all at once. Here, as shown in FIG. 2, both the lock devices 8 and 9 described above are provided on the back surface (exposed portion) of the first operating lever 7 exposed to the outside when the first operating lever 7 is opened. A warning display surface 7b is provided for displaying a warning when a state that is not locked is an abnormal state.

  This warning display surface 7b is formed with a warning display color such as red which makes it easy for the operator P to visually recognize the dangerous state. The warning display surface 7b is hidden from the operator P as a state hidden behind the back of the seat back 2 in the closed state before the first operation lever 7 is opened. However, the warning display surface 7b is exposed to the outside when the first operation lever 7 is opened, and warns of the abnormal state described above so that it is easy to see especially for the operator P standing on the rear side of the vehicle. It is supposed to be displayed.

  Specifically, the warning display surface 7b is directed toward the vehicle rear side when the first operation lever 7 is opened when the seat body 1 is positioned near the storage position below the vehicle body ceiling C. . Further, the warning display surface 7b is easy to peek from the operator P standing on the rear side of the vehicle when the first operation lever 7 is opened when the seat body 1 is located near the use position on the vehicle body floor F. Thus, the surface is directed upward.

  Here, as shown in FIG. 2, the first operating lever 7 is connected to the locking devices 8, 9 by opening the both locking devices 8, 9 together. A pulling operation is performed via the warning cable 23 so that the opening operation is maintained. Thereby, the first operating lever 7 is in a state in which the warning display surface 7b is always displayed as a warning toward the operator P when the both locking devices 8 and 9 are not in the engagement locked state, and the operator P Can recognize abnormal conditions.

  The first operating lever 7 is also pulled through the warning cable 23 in the same manner when both the locking devices 8 and 9 are unlocked even when the second operating lever 30 is opened. It is operated and can be switched to the opened state. These configurations will be described in detail later.

  Returning to FIG. 1, the seat main body 1 described above is rotatably linked to the vehicle body ceiling C by a pair of left and right link members 6 integrally connected to both shoulder openings of the seat back 2. As a result, the seat body 1 moves from the use position (first installation position) on the vehicle body floor F to the vehicle body as the link member 6 rotates around the connection point (connection shaft 6a) with the vehicle body ceiling C. A movement operation is performed between the storage position below the ceiling C (second installation position).

  Here, the seat body 1 is normally on the vehicle body floor F by engaging and locking the back lock device 9 provided on the back surface portion of the seat back 2 to the striker S1 installed on the vehicle body side portion T. It is held in the use position. Here, the back lock device 9 is disposed at the left and right edges of the back portion of the seat back 2, and the striker S1 is disposed on the left and right sides of the vehicle body side portion T corresponding to the position where the back lock device 9 is disposed. It is provided on both sides. Here, the back lock device 9 corresponds to the first lock device of the present invention, and the ceiling lock device 8 corresponds to the second lock device of the present invention.

  The above-described back lock device 9 is normally in a lockable state in which it can be engaged and locked with the striker S1 by an operation of dropping the seat body 1 onto the vehicle body floor F. Here, the engagement lock state between the back lock device 9 and the striker S1 can be released by the opening operation of the first operation lever 7 and the second operation lever 30 described above. When the engagement lock state between the back lock device 9 and the striker S1 is released, the seat body 1 is pushed and moved from the use position on the vehicle body floor F to the storage position below the vehicle body ceiling C. It becomes.

  The retracting movement of the seat body 1 is performed by engaging and locking the ceiling lock devices 8 provided at the lower left and right sides of the seat back 2 against the corresponding strikers S2 installed under the vehicle body ceiling C. By doing so, it is stopped and held at the retracted position below the ceiling C of the vehicle body. Here, the ceiling lock device 8 is always in the lockable state in which it can be engaged and locked to the striker S2 by being pressed against the striker S2 by the storage movement of the seat body 1 in the same manner as the back lock device 9 described above. Being held.

  The engagement lock state between the ceiling lock device 8 and the striker S2 is also released by the opening operation of the first operation lever 7 and the second operation lever 30 described above. Here, the storing movement of the seat main body 1 described above is performed by opening the first operating lever 7 and the second operating lever 30, so that the seat cushion 3 is raised on the front surface of the seat back 2 by the same operation. It is to be performed in the state.

  Next, the configurations of the back lock device 9 and the ceiling lock device 8 will be described with reference to FIGS. Since both locking devices 8 and 9 have substantially the same locking structure 10, these locking structures 10 will be described together below.

  That is, as shown in FIG. 3, each of the locking devices 8 and 9 includes a base plate 11 fixedly installed on the skeleton part of the seat back 2, and a latch pivotally connected to the base plate 11. 12 and the pole 13, the tension spring 14 hooked between the latch 12 and the pole 13, and the release cable 15 (release cables 8a, 8) connected to the first operation lever 7 and the second operation lever 30 described above. 9a) and the operation cable 16 (operation cables 8c and 9c). The lock devices 8 and 9 are configured to engage and lock the latch 12 with the striker S when the striker S (striker S1 and S2) is pushed into the receiving port 11a formed in the base plate 11. Yes.

  More specifically, first, the latch 12 is pivotally connected to the base plate 11 by a support shaft 12e. The latch 12 is normally in a state in which it is urged to rotate counterclockwise in the figure in response to the urging force of the tension spring 14 that is hooked between the hook 12c and the hook 13c of the pole 13. The posture of the initial position is held in contact with the stopper 11b formed on the base plate 11.

  The latch 12 includes an upper jaw 12a projecting into the mouth of the receiving port 11a formed in the base plate 11 and the latch 12 when the latch 12 is rotated clockwise from the initial position (see FIG. 4). In addition, a lower jaw 12b that moves so as to close the receiving port 11a is formed. Further, the latch 12 is formed with a corner portion 12d that engages with the claw portion 13b formed on the pole 13 when the latch 12 rotates clockwise from the initial position (see FIG. 4).

  On the other hand, returning to FIG. 3, the pole 13 is pivotally connected to the base plate 11 by a support shaft 13e. The pole 13 is normally pushed by the corner 12d of the latch 12 in a state of being urged to rotate clockwise in the drawing by receiving the urging force of the tension spring 14 that is hooked between the pawl 13 and the latch 12 described above. It is held in the posture state of the applied initial position. The pawl 13 has an operating arm 13a that is connected to the right end of the release cable 15 and is operated, and a pawl that engages with the corner 12d when the latch 12 rotates clockwise from the initial position. The part 13b is integrally formed.

  In the locking devices 8 and 9 having the above-described configuration, the striker S (the strikers S1 and S2) is pushed into the receiving port 11a of the base plate 11, and the latch 12 that exposes the upper jaw 12a in the mouth is shown clockwise. Pushed in the direction. As a result, as shown in FIG. 4, the latch 12 is brought into a state in which the claw portions 13b of the pole 13 are attracted to the corner portions 12d by the urging force of the tension spring 14 and locked together. Is locked.

  Then, along with this clockwise rotation, the lower jaw 12b moves in the form of wrapping behind the striker S and closes the receiving port 11a. As a result, the striker S is held in an engagement locked state by the latch 12 inside the receiving port 11a. That is, the lock structure 10 having the above-described configuration is in a lockable state in which the lock can be engaged and locked with each other by pushing the release cable 15 into the striker S before the release cable 15 is pulled.

  The engagement lock state of the striker S can be released by pulling the release cable 15 (release cables 8a and 9a) with the first operation lever 7 and the second operation lever 30 (see FIG. 1). . Specifically, as shown in FIG. 3, when the release cable 15 is pulled, the operating arm 13a is operated and the pole 13 is rotated counterclockwise in the figure. As a result, the locking state between the pawl 13b of the pole 13 and the corner 12d of the latch 12 is released, and the latch 12 rotates counterclockwise by the biasing force of the tension spring 14.

  As a result, the striker S is discharged from the receiving port 11a so as to be pushed out by the upper jaw 12a of the latch 12, and the engagement lock state of both is released. Then, when the pulling operation state of the release cable 15 by the first operation lever 7 and the second operation lever 30 (see FIG. 1) is released, the pole 13 is again pressed against the corner 12d of the latch 12. The lock devices 8 and 9 are returned to the lockable state where they can be engaged and locked with the striker S again.

  4, the operation arm 12f (operation arms 8b and 9b) is integrally connected to the above-described latch 12 and the support shaft 12e serving as the rotation shaft thereof. As a result, the operation arm 12f is integrally connected to the latch 12 and rotates together with the latch 12 about the support shaft 12e. The operation arm 12f is connected to an end of an operation cable 16 (operation cables 8c and 9c) connected to a warning operation mechanism 20 described later.

  Here, as shown in FIG. 4, the operation cable 16 is held in a state before the pulling operation in a state where the latch 12 is in the rotational position where the latch 12 is engaged and locked to the striker S. The operation cable 16 is pulled by the first operation lever 7 or the second operation lever 30 (see FIG. 1), and the engagement lock state by the latch 12 is released. As shown in FIG. 3, the tow operation is performed by the operation arm 12f in accordance with the movement rotating in the counterclockwise direction.

  Next, a configuration of the warning operation mechanism 20 for transmitting the operation force obtained by pulling the operation cables 8c and 9c as the operation force for holding the first operation lever 7 described above with reference to FIG. This will be described with reference to FIGS. As shown in FIG. 5, the warning operation mechanism 20 includes a substrate 21 fixedly installed on the skeleton of the seat back 2, an operation plate 22 slidably assembled to the substrate 21, and the operation plate 22 and a warning cable 23 connected to 22.

  Specifically, the operation plate 22 is slidably connected to a long hole 21h formed through the substrate 21 by a pin 22p. Thereby, the operation plate 22 is in a state in which the pin 22p is slidable and rotatable with respect to the substrate 21 within a range in which the pin 22p is slidable in the long hole 21h. An end portion of the operation cable 8c connected to the ceiling lock device 8 described above is connected to the right edge portion of the operation plate 22 in the drawing, and the back lock device 9 is connected to the left edge portion in the drawing. The ends of the connected operation cable 9c are connected.

  These operation cables 8c and 9c are connected to long holes 22a and 22b formed through the operation plate 22 so as to be slidable and rotatable by pins. The end of the warning cable 23 is connected to the pin 22p that connects the operation plate 22 to the substrate 21. The other end of the warning cable 23 is connected to the first operating lever 7 as described above with reference to FIG. 2, and the first operating lever 7 is normally held in the closed position by the spring force of the torsion spring 7c. It is held as a state pulled from the first operation lever 7 side by the force to be applied.

  Returning to FIG. 5, the operation plate 22 described above is in a released state when the back lock device 9 described above with reference to FIG. 1 is engaged and locked to the striker S1 at the use position on the vehicle body floor F. When the operation cable 8c connected to the ceiling lock device 8 is pulled, the right edge to which the operation cable 8c is connected is pulled upward in the figure. However, at this time, the operating plate 22 is rotated in the counterclockwise direction shown in the figure around the pin 22p which is a connection point with the warning cable 23 which is pulled from the first operating lever 7 side. As a whole, the slide operation is not performed on the upper side in the figure.

  At this time, the operation cable 9c connected to the backlock device 9 is configured such that even if the operation plate 22 is rotated as described above, the connection point with the operation plate 22 slides in the long hole 22b. The movement of the operation plate 22 can be released. Similarly, as shown in FIG. 7, when the ceiling lock device 8 is engaged and locked to the striker S2 at the retracted position below the vehicle body ceiling C (see FIG. 1), the back is in the released state. When the operation cable 9c connected to the lock device 9 is pulled, the left edge to which the operation cable 9c is connected is pulled upward in the figure.

  However, in this case, the operation cable 8c connected to the ceiling lock device 8 has a connection point with the operation plate 22 that slides in the long hole 22a even if the operation plate 22 is rotated as described above. As a result, the movement of the operation plate 22 is released. In this way, when only one operation cable 8c (operation cable 9c) is pulled, the entire operation plate 22 is not drawn upward in the figure, but is connected to the warning cable 23 (pin 22p). Therefore, the warning cable 23 is not pulled.

  However, as shown in FIG. 6, the operation plate 22 is operated so that the edge portions on both sides are pulled upward in the figure by both operation cables 8 c and 9 c when both the locking devices 8 and 9 are released. The whole is slid upward. As a result, the warning cable 23 is also pulled in the same direction, and as shown in FIG. 2, the first operation lever 7 connected to the other end side is pulled, and the first operation lever 7 is held in the opened position. It will be in the state.

  Note that the first operating lever 7 is in a state in which either the back lock device 9 or the ceiling lock device 8 is engaged and locked again, as shown in FIG. 5 or FIG. In accordance with the release of the traction operation state, the closing operation is performed by the spring force of the torsion spring 7c. Here, FIG. 8 is a block diagram showing a transmission path through which the operation force for holding the first operation lever 7 in the open position is transmitted from the lock devices 8 and 9.

  Thus, according to the vehicle warning structure of the present embodiment, the warning display surface 7b is provided at the set position of the first operation lever 7 provided for the release operation of both the lock devices 8 and 9. The operator P confirms whether the locking device 8 or 9 on either side is engaged and locked to the vehicle body side structure by checking the set position of the first operating lever 7. Can do. Therefore, the warning display state can be more easily confirmed as compared with the configuration in which the warning display surface 7b is provided for each of the locking devices 8 and 9 or is provided at the set location of each of the locking devices 8 and 9. Can be.

  In addition, since the first operation lever 7 is set on the back surface portion of the seat back 2, when the seat body 1 is in the use position on the vehicle body floor F, the operator P can be seen from the position where the operator P stands on the rear side of the vehicle. And reach easily. Further, when the seat body 1 is in the retracted position below the vehicle body ceiling C, the operator P can easily reach the eyes and hands from inside the vehicle. Therefore, the operation of the first operation lever 7 and the confirmation of the warning display state can be easily performed.

  Further, the warning display surface 7b is formed so that when the first operation lever 7 is opened, a warning display color such as red is displayed on the back surface of the first operation lever 7 serving as the exposed portion. . The warning display surface 7b is maintained in a state in which a warning display color is displayed by keeping the first operation lever 7 opened when both the locking devices 8 and 9 are in the released state. It is. The warning display surface 7b is switched to a state where no warning is displayed when the first operation lever 7 is closed when the locking devices 8 and 9 on either side are in the engagement locked state. Thus, the warning display surface 7b can be embodied as a rational configuration in which a warning display color is added to the exposed portion of the first operation lever 7.

  In addition to the first operation lever 7, a large second operation lever 30 is provided at the position of the back of the seat back 2 where the operator P can easily perform the release operation from the position where the operator P stands on the rear side of the vehicle. Thus, even when the first operating lever 7 is provided at the lower position of the seat back 2 and it is difficult for the operator P to operate from the position standing on the rear side of the vehicle, the releasing operation can be performed by the second operating lever 30. Can be carried out easily using Even when the second operation lever 30 is used for operation, the first operation lever 7 is operated in an interlocked manner so that a warning is displayed. It is possible to confirm whether or not is engaged and locked to the vehicle body side structure.

  Although the embodiment of the present invention has been described with respect to one example, the present invention can be implemented in various forms in addition to the above-described example. That is, the vehicle warning structure targeted by the present invention is a structure having a warning display unit that displays a warning as an abnormal state when the seat body that is the seating part is not engaged and locked to the vehicle body side structure. The present invention can be implemented in various forms other than the uses shown in the above embodiments.

  For example, the seat body can be engaged and locked in the stowed position raised from the use position on the vehicle body floor to the side of the vehicle or in the front-rear direction, or the seat body can be stored in a recess formed in the vehicle body floor. The warning structure of the present invention can also be applied to a seat structure that is engaged and locked. In addition to the retractable seat, for example, the warning structure of the present invention can be applied to a configuration in which the seat body can be engaged and locked at two different positions with respect to the vehicle body side structure. .

  Moreover, although the warning display part was formed as the warning display surface 7b in which the warning display color such as red is displayed on the back surface part exposed when the first operation lever 7 is opened and operated. Separately, a retractable warning display component may be provided, and a warning display may be performed by protruding when both locking devices 8 and 9 are released.
