JP 11-59252 A

  However, in the related art disclosed above, when the footrest is in the unfolded position, when the footrest is not used, the foot hits and gets in the way, so an operation for storing this in the storage position is required. And when using a footrest, operation for canceling | releasing a latching state is needed in order to pull this out from a storage position again. Therefore, every time the use / nonuse of the footrest is repeated while riding, such a storing and unfolding operation must be performed many times, which is troublesome.

  The present invention was devised to solve the above-described problems, and the problem to be solved by the present invention is that when the footrest is not used, it can be moved to a position where it does not interfere with the foot. In addition, when the footrest is used again, there is a need to save time and effort for moving the footrest to the position where the footrest is used.

In order to solve the above problems, the footrest of the present invention takes the following means.
A first invention is a footrest that is disposed on the back of a front seat and is used as a footrest for a seated person of a rear seat, and includes a footboard and a support. The footboard is configured to be able to place a foot of a seated person on the rear seat. The support body is configured to support the tread plate so that it can be turned upside down with respect to the skeleton frame of the front seat. The treadle pivots between the unfolded position that can be used as a footrest for the seated person and the retracted position that is folded in the back part of the seat back of the front seat by the connecting structure of the support to the front seat Supported as possible. The footboard can be locked at the retracted position by an engaging / disengaging structure provided between the front seat and the front seat. An urging member is provided between the support and the front seat so as to urge the support in a turning direction that raises the support from the deployed position toward the retracted position. In the free state where the locked state at the retracted position due to the engagement / disengagement structure is released, the tread plate is raised to an intermediate position higher than at least the center part of the support member by the urging force by the urging force of the urging member. It is to be held as a state.
Here, “the state where the treadle is at an intermediate position higher than at least the center of the support body in the up-and-down rotation” means that the treadle hits the foot of the seated person and the front seat is pushed forward. It is intended that the treadle is retracted and moved up in the turning direction when it is received.
According to the first aspect of the present invention, when the footboard is not used as a footrest, the footboard is raised and folded into the back portion of the seat back of the front seat, so that the retracted structure can be moved to the retracted position. It can be held in a posture state. When the footboard is used as a footrest, the footboard is laid down toward a deployed position that can be used as a footrest by performing an operation of releasing the locked state at the retracted position. At this time, in the free state, the tread plate is held in the intermediate position raised from the deployed position by the urging force of the urging member. In the state where the treadle is in the intermediate position, the treadle is in a higher position than the center part of the support body up-and-down rotation, so that the treadle hits the foot of the seated person in front of the front seat. Even if it receives a pressing force in the direction, it retreats in the raising rotation direction. Therefore, in this intermediate position state, the footboard does not interfere with the seated person's foot. Then, the foot of the seated person is supported by the foot board held at the deployed position by dropping the foot board with his / her foot to the deployed position. When the footboard is no longer used as a footrest, it is returned to the above-described intermediate position by the urging force of the urging member.

Next, in a second aspect based on the first aspect described above, the support body is supported by the skeleton frame of the seat cushion of the front seat so as to be able to turn upside down. The engagement / disengagement structure that can lock the footboard in the retracted position absorbs the shift in the locking position when the backrest angle of the seat back of the front seat is changed with respect to the footboard locked in the retracted position. The treadle can be moved following the movement of the seat back.
According to the second aspect of the present invention, the tread plate locked in the retracted position by the engagement / disengagement structure is folded in the back portion with respect to the movement of changing the backrest angle of the seat back of the front seat. The movement of the seat back is followed while maintaining.

Next, according to a third aspect, in the first or second aspect described above, the support is configured to be rigidly coupled integrally with the footboard. The center portion of the support member that is pivoted up and down with respect to the front seat is set at a position on the rear side of the center portion of the tilt of the seat back of the front seat.
According to the third aspect of the present invention, the tread plate does not invade the seat shape of the front seat by the support body that is rotatably supported at a position rearward of the center portion of the tilt of the seat back of the front seat. It pivots up and down between the retracted position and the retracted position of the seat back back.

Next, according to a fourth aspect of the present invention, in the first or second aspect described above, the footboard is pivotally supported with respect to the support so that the footrest angle can be adjusted and moved. Yes. The central portion of the support body that pivots up and down with respect to the front seat is set at a position coaxial with the central portion of the tilt of the seat back of the front seat.
According to the fourth aspect, it is possible to adjust the footrest angle of the footboard with respect to the support. In addition, this makes it possible to prevent the tread from damaging the seat shape of the front seat even when the center of the support body is pivoted to the center of the tilt of the seat back of the front seat. It pivots up and down between the retracted position and the retracted position of the seat back back.

Next, in a fifth aspect of the present invention based on any one of the first to fourth aspects described above, the rear seat is supported by supporting the lower leg of the seated person by being lifted forward from the front end of the seat cushion. Ottoman that can do is deployed. The footrest is used as a footrest in a posture where the occupant of the rear seat is supported on the lower leg by the ottoman.
According to the fifth aspect, the footrest is used as a footrest in a posture where the occupant of the rear seat is supported on the lower leg by the ottoman.

The present invention can obtain the following effects by taking the above-described means.
First, according to the first invention, by removing the tread plate from the locked state at the retracted position, the tread plate can be held by being biased to the intermediate position without sticking to the foot of the seated person. . From this state, when the treadle is used as a footrest, it can be moved to the unfolded position as a use position by a simple operation by dropping it with the foot. And by removing the foot and cease to be used as a footrest, the footboard can be moved to an intermediate position where it can be easily brought to the deployed position without sticking to the seated person's foot. . Therefore, when the footrest is not in use, it can be moved to a position where it does not interfere with the foot, and when the footrest is used again, the operation for moving the footrest to the position where it is used should not be troublesome. can do.
Furthermore, according to the second invention, the support member is rotatably supported by the cushion frame of the front seat, so that the tread plate is set at an intermediate position regardless of the backrest angle position of the seat back of the front seat. It can be positioned at the position or deployment position. Further, by making the tread plate locked at the retracted position follow the movement of changing the backrest angle of the seat back, the back of the front seat is maintained even when the tread plate is held at the retracted position. It is possible to freely adjust the droop angle.
Furthermore, according to the third invention, the center part of the support body in the up-and-down rotation is set at a position on the rear side of the center part of the tilt of the seat back of the front seat, thereby enabling the seat shape of the front seat to The tread plate can be rotated up and down between the retracted position and the deployed position of the back portion of the seat back so as not to invade.
Further, according to the fourth aspect, the footrest can be adjusted with respect to the support by pivotally supporting the footboard with respect to the support body. Further, the center part of the support body can be arranged so as to reduce the amount of protrusion to the rear side by setting the center part of the support body to be pivoted coaxially with the center part of the tilt of the seat back of the front seat. The tread plate can be rotated upside down between the retracted position and the deployed position of the back portion of the seat back so as not to invade the seat shape of the front seat.

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

First, the structure of the footrest 30 of Example 1 is demonstrated using FIGS.
Here, FIG. 1 is a perspective view showing a schematic configuration of the footrest 30 of the present embodiment. The footrest 30 is disposed on the back of the illustrated front seat 10 and can be used as a footrest by an occupant (sitting person) seated on a rear seat (not shown). .
Hereinafter, the configurations of the front seat 10 and the footrest 30 will be described in detail in order.

That is, the front seat 10 includes a seat back 11 that serves as a backrest portion, a seat cushion 12 that serves as a seating portion, and a headrest 13 that receives the head. Here, the seat back 11 is connected to the seat cushion 12 by reclining devices 14 and 14 provided at lower portions of both sides in the width direction. The reclining devices 14 and 14 are provided so as to be covered with the outside by resin covers 12C provided on both sides of the seat cushion 12.
These reclining devices 14 and 14 are normally held in a locked state in which the backrest angle of the seat back 11 can be fixed. The reclining devices 14 and 14 are operated so as to simultaneously release their locked states by rotating a control lever (not shown) connected thereto. Thereby, since the fixed state of the backrest angle of the seat back 11 is released, the adjustment movement of the backrest angle of the seat back 11 can be performed.

A footrest 30 having a plate-like footboard 31 is provided at the rear end of the seat cushion 12. The footrest 30 includes a tread plate 31 on which a foot of a seated person can be placed, and a support body 32 that supports the tread plate 31 so that the tread plate 31 can pivot up and down with respect to the skeleton frame of the seat cushion 12. The tread plate 31 and the support body 32 are configured to be rigidly coupled together.
The tread plate 31 having the above-described structure has a recessed position formed in a deployed position that can be used as a footrest for a seated person and a back surface portion of the seat back 11 of the front seat 10 due to the connection structure of the support 32 to the seat cushion 12. It is supported so that it can be rotated up and down between the storage position folded in the recess 11D. The state where the footboard 31 is deployed to the deployed position is indicated by the solid line state in FIG. 1, and the state where the footboard 31 is stored at the retracted position is indicated by the solid line state in FIG. The development position of the tread board 31 is set to a posture position floating from the floor F.
In the state where the tread plate 31 is stored in the storage position described above, the engagement pins 33P and 33P formed so as to protrude on both sides thereof are provided with the long holes 11H and 11H formed on both sides of the recess 11D of the seat back 11. By being engaged with each other, it is possible to hold the storage position. The holding state of the tread plate 31 can be removed by pulling the operating lever 33 provided on the back surface of the tread plate 31.

Specifically, the engagement / disengagement structure between the tread plate 31 and the seat back 11 is configured as follows.
That is, the engagement pins 33P and 33P are normally held in a state of protruding from both side portions of the tread plate 31 by urging as shown in FIG. The engaging pins 33P and 33P are pulled into the shape of the tread plate 31 against the above-mentioned bias by performing a pulling operation of the operating lever 33. Here, in the protruding state, the engaging pins 33P and 33P interfere with both side portions of the recess 11D by folding the tread plate 31 into the back surface portion of the seat back 11. However, the engaging pins 33P and 33P are formed by cutting out the tip portion side surface that interferes with both side portions of the recess 11D in a tapered shape.
As a result, as shown in FIG. 2, the engaging pins 33P and 33P fold the tread plate 31 toward the back surface portion of the seat back 11, so that the tapered notch surface becomes a guide surface. Then, it is pressed inward by the both side portions of the recess 11 </ b> D and pulled into the tread plate 31. Then, when the tread plate 31 is stored in the recess 11D of the seat back 11, each engagement pin 33P, 33P reaches the position where the long holes 11H, 11H are present, whereby each engagement pin 33P, 33P is energized. As a result, the long holes 11H and 11H are projected and engaged. As a result, the tread plate 31 is held in a state of being stored in the storage position in the recess 11 </ b> D formed on the back surface portion of the seat back 11.
As described above, the locking state of the tread plate 31 can be released by releasing the engagement state between the engagement pins 33P and 33P and the long holes 11H and 11H by the pulling operation of the operation lever 33. As a result, the tread plate 31 can be pulled out from the retracted position toward the deployed position.

Here, the long holes 11 </ b> H and 11 </ b> H formed on both side portions of the seat back 11 described above are formed so as to extend straight in the height direction along the back surface shape of the seat back 11. Thereby, the engagement pins 33P and 33P engaged with the long holes 11H and 11H can freely slide and move within the range of the hole shape extending straight.
Therefore, with the engagement structure in which the engagement pins 33P and 33P are slidably engaged, the front seat 10 has the backrest angle of the seat back 11 even when the tread 31 is stored in the storage position. Adjustment movement can be performed. That is, as shown in FIG. 3, when the backrest angle of the seat back 11 of the front seat 10 is changed in a state where the tread 31 is stored in the storage position, the engagement pins 33P and 33P receive this movement. Then, it slides in the long holes 11H and 11H. As a result, the tread plate 31 follows the movement of changing the tilt angle of the seat back 11 while maintaining the state where the tread plate 31 is attached to the back surface portion of the seat back 11.
The recess 11D for storing the tread 31 has a height dimension that is slightly larger than the tread 31 so that the tread 31 can be allowed to move up and down when the inclination angle of the seat back 11 is changed. Is formed.

By the way, returning to FIG. 1, when the tread board 31 is used as a footrest, the tread plate 31 is moved toward the unfolded position indicated by the solid line in FIG. It will be pulled out. However, when the tread board 31 is in its free state, that is, when the seated person's feet are not placed, the tread board 31 is held in the intermediate position indicated by the phantom line by the bias.
Here, the state in which the footboard 31 is in the intermediate position is well shown in FIG. As shown in the figure, in the state where the tread plate 31 is in the intermediate position (virtual line state), the tread plate 31 is raised to a position higher than the center part of the support body 32 in the up-and-down rotation. ing. Thereby, the tread board 31 is made into the state which does not become a hindrance to the leg part of the seated person of a backseat seat.
That is, in the state where the tread board 31 is in the intermediate position, for example, when a force is applied to the foot of the seated person so that the foot is pressed in the forward direction, the tread board 31 is turned up toward the retracted position. Retreat in the direction. Therefore, even if the foot of the seated person hits the footboard 31, the footboard 31 does not stick to the foot, and therefore does not interfere with the foot.

And when using the tread board 31 in this intermediate position as a footrest, a seated person should just drop the tread board 31 with a leg | foot, etc. to a deployment position. As a result, since the footboard 31 falls to the deployed position and is held in that position, the foot of the seated person can be supported by the footboard 31 held in the deployed position.
Then, when the foot of the seated person is removed, the tread board 31 is returned to the above-described intermediate position by urging again.
Hereinafter, a specific configuration of the footrest 30 will be described in detail.

Here, in FIG. 5, a frame structure inside the footrest 30 is shown in a perspective view. As shown in the figure, the footrest 30 supports a flat tread 31 for placing a foot portion, and supports the tread 31 so that it can be turned upside down with respect to the front seat 10 (see FIG. 1). And a support 32 for carrying out the operation.
The support body 32 includes support frames 32A and 32A that are rigidly coupled to both sides of the tread plate 31, and a pipe-shaped reinforcement frame 32B that is bridged between the support frames 32A and 32A and reinforces the support strength of the tread plate 31. , 32B. These support frames 32A, 32A have a cross-sectional shape bent into a “U” sign shape, and are pivotable to fixed frames 32F, 32F rigidly coupled to the skeleton frame of the seat cushion 12 of the front seat 10. It is supported. Thereby, the support body 32 is connected with respect to the front seat 10 so that rotation is possible.

Specifically, the connection structure between the support frames 32A and 32A and the fixed frames 32F and 32F is shown in detail in FIG. In FIG. 6, only the connection structure between the support frame 32A on one side and the fixed frame 32F is shown, but the connection structure on the other side is also symmetrical, but the substantial configuration is the same. It has become.
As shown in the drawing, a stopper 32S serving as a rotation restricting member is attached to the support frame 32A by attachment pins P and P. The support frame 32A and the fixed frame 32F are pivotally supported so as to be rotatable relative to each other by a pivot pin Q inserted therethrough. This pivot pin Q is inserted in the plate thickness direction from the fixed frame 32F side, and is fixed so as not to be removed by the fixing ring W at a point penetrating the support frame 32A in the plate thickness direction. The pivot pin Q is welded to the fixed frame 32F and integrally coupled thereto.
A torsion spring S formed by spirally winding a spring steel plate is hooked between the pivot pin Q and the stopper 32S. The torsion spring S has an end on the inner peripheral side fixed to a spring hooking groove Qd formed on the shaft support pin Q, and an end on the outer peripheral side is fixed to the spring 32S. It is hooked and fixed in the groove Sd. As a result, the support frame 32A is urged to rotate counterclockwise as shown in the figure with respect to the fixed frame 32F, and the tread plate 31 is held up to the intermediate position described above with reference to FIG. It has become.
Returning to FIG. 6, the rotation of the support frame 32 </ b> A in the clockwise direction with respect to the fixed frame 32 </ b> F is regulated by the stopper 32 </ b> S coming into contact with the locking portion Fs formed on the fixed frame 32 </ b> F. It has become. As a result, the tread plate 31 is held at the position where it is dropped into the unfolded position described above with reference to FIG.
Here, as shown in FIG. 4, the center of the tilting of the seat back 11 of the front seat 10 is the center of the tilting of the seat back 11 of the front seat 10. It is set at a position on the rear side. As a result, when the support body 32 is turned upside down, the support body 32 and the footboard 31 can suppress the amount of interference with the seat shape of the front seat 10, so that the footrest 30 can be stored without affecting the seat shape. It can be rotated up and down between the position and the deployed position.

Subsequently, a method of using the present embodiment will be described.
That is, as shown in FIG. 2, when the footrest 30 is not used as a footrest, the footrest 30 is held in a retracted position in which the footrest 30 is folded into the back surface portion of the seat back 11 of the front seat 10. Therefore, when the footrest 30 is used as a footrest, the operation lever 33 may be pulled to release the holding state at the storage position. As a result, as shown by the phantom lines in the figure, the tread plate 31 turns down toward the deployed position, and is held in an intermediate position.
In the state in which the tread 31 is in the intermediate position, the tread 31 is in a higher position than the center of the support body 32 in the up-and-down rotation, so that the tread 31 does not interfere with the foot of the seated person. It has become. Then, as shown in FIG. 1, the foot of the seated person is supported by the foot board 31 held at the deployed position by dropping the foot board 31 with his / her foot to the deployed position.
The tread 31 is returned to the above-described intermediate position by urging when it is no longer used as a footrest. Therefore, when the tread plate 31 is not used, it can be held in the retracted position by raising it and folding it into the back of the seat back 11 of the front seat 10.

As described above, according to the footrest 30 of the present embodiment, the tread plate 31 is removed from the locked state at the retracted position, so that the tread plate 31 is biased to the intermediate position where it does not stick to the foot of the seated person. Can be held. From this state, when the tread board 31 is used as a footrest, the footboard 31 can be moved down to the deployed position, which is a use position, by dropping it with a foot. Then, by removing the foot and cease to be used as a footrest, the footboard 31 can be moved to an intermediate position where it can be easily brought to the unfolded position without sticking to the seated person's foot. it can. Therefore, when the footrest 30 is not used, it can be moved to a position where it does not interfere with the foot, and when the footrest 30 is used again, the operation for moving the footrest 30 to the position where the footrest 30 is used does not take time. Can be.
Further, the support 32 is rotatably supported by the cushion frame of the front seat 10, so that the tread 31 is set at an intermediate position or unfolded regardless of the backrest angle position of the seat back 11 of the front seat 10. Can be positioned. Further, since the tread plate 31 locked in the retracted position can be made to follow the movement of changing the backrest angle of the seat back 11, even if the tread plate 31 is held in the retracted position, the front seat It is possible to freely adjust the backrest angle of the seat 10.
Further, the center portion of the support body 32 that is pivoted up and down is set to a position on the rear side of the center portion 14R of the tilt of the seat back 11 of the front seat 10 so that the seat shape of the front seat 10 is not affected. In this way, the tread plate 31 can be turned upside down between the retracted position and the deployed position of the back of the seat back 11.

Then, the structure of the footrest 40 of Example 2 is demonstrated using FIGS. In addition, in a present Example, about the location which shows the structure and effect | action substantially the same as the footrest 30 demonstrated in Example 1, it attaches | subjects the same code | symbol and abbreviate | omits description and will explain in detail about a different location. .
As shown in FIG. 7, the footrest 40 of the present embodiment has a tread plate 41 pivotally supported with respect to a support 42 so that the footrest angle can be adjusted and moved. And the center part of the rotation rotation with respect to the front seat 10 of the support body 42 is set to a position coaxial with the center part 14R of the reclining device 14 which is the center of tilting of the seat back 11 of the front seat 10. Yes. In other words, even if the center part of the support body 42 is turned upside down at a position coaxial with the center part of the tilt of the seat back 11 of the front seat 10, the tread plate 41 can be rotated with respect to the support body 42. Therefore, the tread plate 41 and the support 42 can be turned upside down between the retracted position and the deployed position of the back portion of the seat back 11 without affecting the seat shape of the front seat 10. ing.

Here, in FIG. 8, a frame structure inside the footrest 40 is shown in a perspective view. As shown in the figure, the footrest 40 has a frame-frame-like step board 41 in which reinforcing frames 41A, 41B,... Are bridged in a frame, and the step board 41 is connected to the front seat 10 (FIG. 7). And a support body 42 for supporting the support member so that it can be turned upside down. Engagement pins 43P and 43P that engage with the long holes 11H and 11H formed in the seat back 11 of the front seat 10 are provided on the frame frames on both sides of the footboard 41 so as to protrude.
The support body 42 includes support frames 42A and 42A provided on both sides of the tread plate 41, and a pipe-shaped reinforcement frame that spans between the support frames 42A and 42A and reinforces the support strength of the support body 42. 42B. The support frames 42A and 42A are pivotally supported by fixed frames 42F and 42F that are rigidly coupled to the skeleton frame of the seat cushion 12 of the front seat 10. The connection structure between the support frames 42A and 42A and the fixed frames 42F and 42F is shown in detail in FIG. 10, but is substantially the same as the structure described with reference to FIG. 6 in the first embodiment. ing. That is, the support frame 42A is configured to be restricted from rotating in the clockwise direction in the figure by the stopper 42S attached thereto coming into contact with the locking portion Fs formed on the fixed frame 42F. .

FIG. 9 shows a connection structure between the footboard 41 and the support frames 42A and 42A. Note that FIG. 9 shows only the connection structure between the one-side footboard 41 and the support frame 42A, but the other-side connection structure is also symmetric in arrangement, but the substantial configuration is the same. ing.
As shown in the figure, a stopper 41 </ b> S serving as a rotation restricting member is integrally attached to the frame of the tread plate 41. The tread plate 41 and the support frame 42A are pivotally supported by a pivot pin R so as to be relatively rotatable. The shaft support pin R is inserted through the seat ring A from the fixed frame 42F side in the plate thickness direction, and is fixed so as not to be detached by the fixing member Y at a point penetrating the support frame 42A in the plate thickness direction. ing.
A coil spring T is hooked between the support frame 42A and the stopper 41S. One end of the coil spring T is hooked and fixed to a spring hooking portion Ad formed on the support frame 42A, and the other end is inserted into a spring hooking groove Sb formed on the stopper 41S. It is hooked and fixed. As a result, the tread plate 41 is urged to rotate counterclockwise in the figure with respect to the support frame 42A, and the tread plate 41 is held in a state where it is raised to the position indicated by the phantom line in FIG. It has become so.
The counter-clockwise rotation of the stepping plate 41 with respect to the support body 42 is restricted by the stopper 41S coming into contact with the left-side engaging portion As shown in FIG. 6 formed on the support frame 42A. It has come to be. And the rotation of the tread plate 41 in the illustrated clockwise direction with respect to the support body 42 is regulated by the stopper 41S coming into contact with the engaging portion As on the right side in the figure. As a result, the footboard 41 is held in a state where it is dropped to the position indicated by the solid line in FIG.

By the way, in this embodiment, as shown in FIG. 7, an ottoman 25 that can support the lower leg of the seated person is provided on the rear seat 20 on which the seated person is seated. The ottoman 25 is raised to the front from the front end of the seat cushion 22 so that the occupant 25 can be switched to a state in which the lower leg of the seated person can be supported.
Accordingly, as shown in FIG. 7, the seated person of the rear seat 20 further supports the foot by the footrest 40 in the comfortable posture state in which the seatback 21 is laid and the ottoman 25 supports the lower leg. It can be used.
The configuration of the rear seat 20 is the same as the configuration of the front seat 10. That is, the rear seat 20 includes a seat back 21 that serves as a backrest portion, a seat cushion 22 that serves as a seating portion, and a headrest 23 that receives the head. The seat back 21 is connected to the seat cushion 22 by the reclining devices 24 and 24 so that the backrest angle can be adjusted and moved.

Thus, according to the footrest 40 of the present embodiment, the footrest 41 can be adjusted for the footrest angle by pivotally supporting the footboard 41 with respect to the support 42. . Further, the center portion of the support body 42 is set so as to be coaxial with the center portion of the tilting of the seat back 11 of the front seat 10 so that the amount of protrusion to the rear side is reduced. Even so, the tread plate 41 can be turned upside down between the retracted position and the deployed position of the back portion of the seat back 11 so as not to invade the seat shape of the front seat 10.
Furthermore, an occupant seated in the rear seat 20 can double the comfort function by using the ottoman 25 provided in the rear seat 20 and the footrest 40 provided in the front seat 10 together.

Although the embodiment of the present invention has been described with reference to two examples, the present invention can be implemented in various forms in addition to the above-described example.
For example, the intermediate position where the footrest of the footrest is held in the free state may be a position higher than the center part of the support member for turning up and down. Therefore, this intermediate position can be set to various angular positions in accordance with the specifications in the vehicle other than the angular positions shown in the above embodiment.
Moreover, although the tread plate can be held in a state of being stored in the recessed portion of the back portion of the seat back, the holding structure (engagement / disengagement structure) is limited to the engagement structure of the engagement pin and the long hole. Instead, various engagement / disengagement structures can be applied. However, if this engagement / disengagement structure cannot absorb the displacement of the locking position when the seat back backrest angle is changed, the footrest provided on the seat cushion side can be tilted. It is necessary to keep in mind that it will not be possible to follow the movement to be performed.
Moreover, although the structure in which the footrest is connected to the seat cushion side of the front seat is shown, the structure may be connected to the seat back side. However, in this case, it should be noted that the intermediate position and the unfolded position of the footboard change depending on the backrest angle position of the seat back.

3 is a perspective view schematically illustrating a configuration of a footrest of Example 1. FIG. It is a perspective view showing the state which stored the footrest. It is the perspective view showing the state which changed the backrest angle of the seat back in the state which stored the footrest. It is the side view showing the state which moved the footrest in an intermediate position to the deployment position. It is the perspective view which showed the frame structure of the footrest. It is a disassembled perspective view showing the assembly structure of a support body. It is the side view which represented the structure of the footrest of Example 2 roughly. It is the perspective view which showed the frame structure of the footrest. It is a disassembled perspective view showing the assembly structure of a footboard. It is a disassembled perspective view showing the assembly structure of a support body.
