The armrest A1 has an armrest body 11, and a stay 12 engaged with one end side of the armrest body 11 to support the armrest body 11. The stay 12 is rotatably supported to the side of the seat cushion S2, and rotated independently of the tilting motion of the seat back S1.

Description

  The present invention relates to a vehicle seat provided with an armrest, and more particularly to a vehicle seat provided with an armrest that can hold the armrest in an optimum position even when the seatback is tilted by a reclining mechanism.

  2. Description of the Related Art Conventionally, as a vehicle seat, for example, as shown in FIG. 12, an armrest A ′ is known that is rotatably attached to a seat back S1 ′. In such a vehicular seat, the armrest A ′ can be rotated upward and along the side of the seat back S1 ′. However, as shown in FIG. 13, in the vehicle seat provided with the armrest A ′, the vehicle seat S ′ further provided with the reclining mechanism R ′ generally restricts the movement of the armrest A ′ rotating downward. Therefore, when the seat back is tilted rearward, the angle of the armrest A ′ with respect to the seat back S1 ′ is maintained.

  As a result, the armrest A ′ is lifted upward as the seat back S1 ′ tilts, and when the occupant puts his / her arm on the armrest A ′, the position of the armrest A ′ is high and comfort may be impaired. there were.

  Thus, with respect to the problem that the armrest is lifted upward as the seatback tilts and the comfort at the time of sitting is reduced, Patent Document 1 discloses a seat cushion frame, a seatback frame, an armrest, A reclining seat with an armrest having a configuration in which a parallelogram parallel link mechanism is formed by an arm attached to the tip of the armrest is disclosed.

  In the reclining seat disclosed in Patent Document 1, the arm pivotally supported on the front end of the armrest is pivotally supported on the seat cushion frame so that the armrest and the seat cushion frame are substantially parallel, while the rear end of the armrest is Is pivotally supported by the seat back frame. With this configuration, the rear end of the armrest is pulled backward as the seatback is tilted backward, but the armrest is held substantially horizontally by the arm attached to the armrest. Therefore, even when the seat back is tilted, the armrest is held substantially horizontally, so that the occupant can easily put his / her arm.

Japanese Utility Model Publication No. 60-113227

  In the reclining seat disclosed in Patent Document 1, since the armrest and the seat cushion are held in parallel, the occupant can put his arm on the armrest in a natural state, and can obtain a comfortable seating feeling.

  However, the seat cushion of Patent Document 1 has a configuration in which the rear end of the armrest is pivotally supported by the seatback frame, and the front end of the armrest is pivotally supported by the seat cushion frame via the arm. And since the number of parts increases, there existed a problem that the manufacturing process of a sheet | seat became complicated.

  Moreover, in patent document 1, an armrest is accommodated so that an armrest may be rotated to a seat back side surface and it may be along a seat back side surface. Therefore, since the armrest is formed with a length that does not protrude from above the seatback when stored, it is difficult to ensure a sufficient length. As a result, the occupant may not be able to put the entire arm on the armrest, and there is a problem that sufficient comfort cannot be obtained.

  Further, in Patent Document 1, when storing the armrest, the armrest is stored along the side surface of the seat back, so that the armrest is always visually recognized and the appearance is not good.

  An object of the present invention is for a vehicle having an armrest that has a simple and lightweight structure and that can provide a comfortable seating feeling by holding the armrest in an optimum position even when the seat back is tilted. To provide a sheet. Another object of the present invention is to provide a vehicle seat provided with an armrest that can secure a sufficient length of the armrest and obtain a comfortable seating feeling. Furthermore, the other object of this invention is to provide the vehicle seat provided with the armrest which can be accommodated without impairing appearance when the armrest is accommodated.

  According to the vehicle seat provided with the armrest of the present invention, the subject is a vehicle seat provided with a seat cushion, a seat back coupled to the seat cushion via a reclining mechanism, and an armrest, The armrest has an armrest main body and a stay that is locked to one end of the armrest main body and supports the armrest main body, and the stay is pivotally supported on the side surface of the seat cushion, This is solved by rotating independently of the tilting operation of the seat back.

Thus, in the vehicle seat provided with the armrest of the present invention, the armrest rotates independently with the tilting operation of the seat cushion. Therefore, even if the seat back is tilted by the reclining mechanism, the position of the armrest does not change, so the position on which the occupant's arm is placed does not change, and the armrest is always held at the optimal position.
Further, the armrest can be stored along the side surface of the seat cushion by a stay that is rotatably attached to the side surface of the seat cushion. Therefore, when the armrest is stored, the armrest is stored in a place that is difficult to see, so that the vehicle seat having a good appearance can be obtained.

At this time, as in claim 2, it is preferable that the armrest body is configured not to be locked to the seat back.
Thus, since the armrest body is not configured to be locked to the seat back, the armrest can be independently rotated with respect to the tilting operation of the seatback, and the configuration of the armrest can be further simplified.
Therefore, since a locking member for locking the armrest body with respect to the seat back is not required, the weight of the entire seat can be reduced. Moreover, since the number of parts does not increase, the assembly work process of the vehicle seat can be simplified.

At this time, as in claim 3, it is preferable that the armrest body is attached to the stay so as to be rotatable.
As described above, when the armrest body can be rotated with respect to the stay, the armrest can be further miniaturized and stored when the armrest is stored, and the storage performance is improved. Moreover, since the armrest is reduced in size when the armrest is stored, the length of the armrest body can be secured large.

Furthermore, as in claim 4, it is preferable that the armrest body is slidably attached to the stay along the longitudinal direction of the stay.
Thus, when the armrest body can slide along the longitudinal direction of the stay, it is possible to further save space when the armrest is stored. Therefore, the appearance when the armrest is stored is not impaired.

According to a fifth aspect of the present invention, it is preferable that the stay is slidably contacted along a side surface of the seat cushion and is slidably attached along the longitudinal direction of the stay.
Thus, if the stay is in sliding contact with the side surface of the seat cushion and is slidable along the longitudinal direction of the stay, the space can be further saved when the armrest is stored.

At this time, as in claim 6, it is preferable that the stay is pivotally supported at a substantially central portion in the front-rear direction of the seat cushion.
Thus, the length of the armrest body can be sufficiently secured by pivotally supporting the stay in front of the center portion in the front-rear direction of the seat cushion. That is, by extending the armrest body from the front to the rear, a large portion for supporting the occupant's arm can be secured.
Furthermore, in a vehicle seat provided with a reclining mechanism, the rear side of the seat cushion generally has a shape protruding sideward due to the width of the reclining mechanism. Therefore, by disposing the stay of the armrest in front of the seat cushion, the armrest is disposed in a narrow portion in the width direction of the seat cushion (a portion that enters inside the end portion of the reclining mechanism). As a result, the width of the entire seat can be reduced without the armrest protruding sideways.
Further, by arranging the stay so as to avoid the substantially central portion of the seat cushion in the front-rear direction, a space for arranging other articles such as a cup holder is secured on the side surface of the seat cushion in the front-back direction. . Therefore, the seating feeling of the passenger can be improved.

At this time, as in claim 7, when the armrest is in use, the armrest surface of the armrest body is preferably held horizontally.
Thus, in the vehicle seat of the present invention, since the armrest does not follow the tilting operation of the seat back, the use state can always be maintained independently of the movement of the seat back. And when the armrest is in use, the armrest surface of the armrest body can be held horizontally, so that the occupant always uses the armrest in the optimal position and state even when adjusting the inclination angle of the seat back. can do.

At this time, as in claim 8, when the seat back is at the maximum tilt position, it is preferable that the armrest is stored below the highest position of the seat back.
In the vehicle seat of the present invention, since the seat back and the armrest are not interlocked, when the armrest is stored with the seatback being most inclined, the armrest is stored below the highest position of the seatback. Therefore, the armrest does not protrude upward from the seat back, so that the armrest can be stored well.

According to the first aspect of the present invention, since the position of the armrest can always be maintained in an optimal state without depending on the tilting operation of the seat back, it is possible to provide a vehicle seat having a good seating feeling. In addition, since the armrest can be stored on the side of the seat cushion, a vehicle seat having a good appearance can be provided.
According to the invention of claim 2, the configuration is simple and the vehicle seat can be light.
According to the third aspect of the present invention, when the armrest is stored, the armrest can be reduced in size and stored. Furthermore, since the length of the armrest can be ensured, it is possible to provide a vehicle seat having a good seating feeling.
According to invention of Claim 4, since the accommodation location of an armrest can be made small, storability is further improved and the vehicle seat with a favorable external appearance can be provided.
According to the invention of claim 5, it is possible to provide a vehicle seat with higher armrest storage performance.
According to the invention of claim 6, it is possible to secure a sufficiently large range in which an occupant can put his / her arm, and to provide a vehicle seat with good seating properties.
According to the seventh aspect of the present invention, the portion on which the occupant puts his / her arm is held horizontally without depending on the inclination angle of the seat back, so that the occupant can obtain a comfortable seating feeling. be able to.
According to the eighth aspect of the present invention, when the armrest is stored, the armrest does not protrude from the seatback, and a vehicle seat with good storage performance can be provided.

(Embodiment 1)
With reference to FIG. 1 thru | or FIG. 5, the vehicle seat S provided with armrest A1 which concerns on Embodiment 1 is demonstrated.
As shown in FIG. 1, the vehicle seat S includes a seat back S1, a seat cushion S2, and an armrest A1, and the seat back S1 and the seat cushion S2 have cushion pads 1a and 2a placed on the seat frame. The skin material 1b is covered with 2b. In addition, in FIG. 1, armrest A1 is in the state at the time of use.

The seat frame of the vehicle seat S includes a seat back frame (not shown) constituting the seat back S1 and a seating frame F constituting the seat cushion S2.
The seat back S1 has the cushion pad 1a mounted on the seat back frame as described above, and is covered with the skin material 1b from above the cushion pad 1a, and supports the back of the occupant from the rear.

  The seat cushion S2 is configured such that the cushion pad 2a is placed on the seating frame F as described above, and is covered with the skin material 2b from above the cushion pad 2a to support the occupant from below. The seat cushion S2 includes a cover C on the side of the cushion pad 2a covered with the skin material 2b.

The seating frame F is supported by a leg portion, and an inner rail is attached to the leg portion, and is assembled in a slide type that can be adjusted in the front-rear position with an outer rail installed on the vehicle body floor.
The rear end portion of the seating frame F is connected to a seat back frame (not shown) via a reclining mechanism R.
As long as the reclining mechanism R supports the seat back S1 to be tiltable with respect to the seat cushion S2, a known configuration can be used.

  In the present embodiment, the armrest A1 is disposed on the side portion of the vehicle seat S, and is attached to the side surface of the seat cushion S2 (more specifically, the seating frame F constituting the seat cushion S2). (See FIG. 2). In the present embodiment, the armrest A1 is configured to be attached to the seating frame F via the cover C, but may be configured to be attached to the seating frame F via the cushion pad 2a and the skin material 2b.

  The armrest A1 may be directly attached to the seating frame F, or may be attached to the cover C as long as it has sufficient rigidity to support the occupant's arm. However, as shown below, the configuration in which the shaft member 13 is locked to the seating frame F is particularly preferable because the portion to be locked has high rigidity and can firmly hold the armrest A1. .

  The armrest A <b> 1 includes an armrest body 11, a stay 12 fixed to the armrest body 11, and a shaft member 13. The armrest body 11 is a long member that supports the occupant's arm, and a pad material supported by a metal core is covered with a decorative member such as a trim cover. And the upper end part of the stay 12 which consists of a flat plate-shaped elongate member is adhering to the side surface 11a (surface by the side of the seat cushion S2) of the armrest main body 11, and the longitudinal direction of the armrest main body 11 and the longitudinal direction of the stay 12 are fixed. The directions are fixed so as to cross each other substantially perpendicularly. At this time, the stay 12 is attached so that the upper end of the stay 12 does not protrude from the armrest surface 11 b of the armrest body 11.

  The stay 12 is fixed to the core material of the armrest body 11. And the stay 12 should just be provided with the rigidity which can endure a passenger | crew's load, and is formed with a metal, resin, etc. FIG. In addition, the stay 12 may be configured to be covered with a cushion material or a skin material in order to improve the appearance and the seating feeling.

  In the armrest A <b> 1 in the use state (the state of FIG. 1), the front end portion of the armrest body 11 is locked (fixed) to the upper end portion of the stay 12. On the other hand, the rear end of the armrest body 11 is not locked to another member and is a free end. In this embodiment, the armrest body 11 and the stay 12 are formed in a substantially L shape in a side view. However, if the armrest surface 11b of the armrest A1 can be disposed horizontally, the armrest body 11 and the stay 12 have a substantially V shape in a side view. It may be formed.

The stay 12 has a locking hole 12a formed at the lower end thereof, and the shaft member 13 is inserted into the locking hole 12a. The shaft member 13 is further inserted into a locking hole Ca formed in the cover C and a locking hole Fa formed in the seating frame F. Then, by fitting the fitting member 14 and the shaft member 13 disposed on the locking hole Fa side, the armrest A1 comes into close contact with the seat cushion S2 (more specifically, the seating frame F), and the seat It is pivotally supported so as to be rotatable in the front-rear direction along the side surface of the cushion S2.
Although not shown in FIG. 2, a cushion pad 2a and a skin material 2b may be interposed between the seating frame F and the cover C.

  As the shaft member 13 and the fitting member 14, for example, a pivot shaft, a plain shaft, or the like can be used, and any known configuration can be used as long as the armrest A1 is attached to be pivotable in the front-rear direction. In order to prevent the stay 12 from rotating forward and backward when the armrest A1 is used, the seat cushion S2 or the armrest A1 is provided with a rotation stopper (not shown) in each direction. A known structure is used as the structure of the rotation stopper.

  Next, the operation when the armrest A1 is stored will be described with reference to FIG. In FIG. 3A, the use state is indicated by a solid line, and the storage state is indicated by a two-dot chain line. In order to return the armrest A1 from the housed state to the used state, an operation opposite to the operation described below is performed.

  As shown in FIG. 3A, the armrest A1 is attached so that the stay 12 can rotate with respect to the side surface of the seat cushion S2. Since the armrest body 11 is not locked to the seat back S1, the stay 12 can be rotated independently of the tilting operation of the seat back S1.

  Therefore, when the above-described rotation stopper is released when the armrest A1 is stored, the stay 12 can rotate forward. 3B shows a state in which the stay 12 is rotated until the stay 12 is horizontal, but as will be described later, the front end side (side on which the armrest body 11 is attached) is further downward. It may be rotated.

  On the other hand, when the armrest A1 is in use, the rearward rotation of the armrest A1 is prevented by a rotation stopper (not shown). At this time, it is preferable that a rotation stopper is provided in the seating frame F because the stay 12 can be stably prevented from rotating.

  In the state of use of the armrest A1, the stay 12 is prohibited from rotating not only by the backward rotation stopper but also by the rotation stopper that prevents forward rotation. It is fixed to become. As a result, the armrest surface 11b of the armrest body 11 is disposed substantially horizontally.

  As described above, the vehicle seat S of the present invention has a configuration in which the armrest body 11 is not locked to the seatback S1, and the armrest A1 is locked only to the seat cushion S2. Therefore, even when the seat back S1 is tilted, the armrest A1 (more specifically, the stay 12 provided in the armrest A1) is independent of the tilting operation of the seatback S1, and the movement of the seatback S1 Since it does not follow, armrest A1 can always be hold | maintained in an optimal position.

  Moreover, since armrest A1 can be made to incline forward as mentioned above, storage property is favorable and also does not impair an external appearance. Then, as shown in FIG. 4, the armrest A1 is stored even when the seat back S1 is tilted back to the maximum extent (that is, when the seat back S1 is at the maximum back tilt position or when it is fully flat). At this time, the armrest A1 can be stored so that the armrest A1 is located below the highest position of the seat back S1. Therefore, the armrest A1 (more specifically, the armrest main body 11) can be stored without protruding upward from the highest position (line Y in FIG. 4) of the seat back S1, so that the storage is excellent. .

  The stay 12 of the armrest A1 is disposed forward of the substantially central portion (line X in FIG. 3) of the seat cushion S2 in the use state of the armrest A1. In general, the back of the cover C provided in the seat cushion S2 is formed so as to bulge to the side of the seat in order to protect the reclining mechanism R (see FIG. 5). Therefore, the stay 12 is not attached to the bulging portion of the cover C (the rear side of the seat) but attached to the front, so that the stay 12 is disposed inside the bulging portion of the cover C. As a result, the overall seat width of the vehicle seat S including the armrest A1 does not increase, which is preferable. As shown in FIG. 5, when the surface of the cover C is located on the inner side of the cushion material 2a at the position where the armrest A1 is attached when viewed from directly above, the stay 12 is positioned on the side surface of the seat cushion S2 (more details). The shaft member 13 is preferably attached so as to slightly protrude from the side of the seat cushion S2 so as to be in sliding contact with the skin material 2b).

  In addition, since the stay 12 is not attached to the substantially central portion in the front-rear direction but is provided in the front, the armrest A1 can ensure a large range in which the arm of the occupant is placed (that is, the length of the armrest body 11). Is preferable.

  Further, by arranging the stay 12 in the front and rotating the stay 12 forward rather than backward when the armrest A1 is stored, the space P is always secured at the substantially central portion in the front-rear direction of the seat cushion S2. The Therefore, other articles such as a cup holder can be disposed in the space P (see FIG. 3).

(Embodiment 2)
Next, the armrest A2 according to the second embodiment will be described below with reference to FIGS.
The vehicle seat S including the armrest A2 according to the second embodiment is characterized in that the vehicle seat S includes an armrest body 111 and a stay 112 having a configuration different from that of the armrest A1 according to the above-described embodiment. In addition, since the other structure is common in the vehicle seat S of the said embodiment, the description is abbreviate | omitted.

The armrest A2 of the second embodiment is characterized in that the armrest body 111 is pivotally supported with respect to the stay 112 so as to be rotatable.
The armrest body 111 is provided with a support shaft 15. The support shaft 15 is fitted along the short direction (width direction) of the armrest body 111 and is fixed to the armrest body 111.

  One end of the support shaft 15 is inserted into a substantially circular through hole 112 b formed in the upper end portion of the stay 112, and the armrest body 111 is pivotally supported so as to be rotatable with respect to the stay 112. Yes. More specifically, when the armrest A2 is in use (the state shown in FIG. 6A), the support shaft 15 is inserted through the front end of the armrest main body 112, and is inserted through the upper end portion of the stay 112. It is supported.

  At this time, the support shaft 15 is inserted from the side surface 111a (seat cushion S2 side surface) side of the armrest body 111, and the longitudinal direction of the armrest body 111 and the longitudinal direction of the stay 112 are substantially orthogonal. And the armrest surface 111b of the armrest main body 111 is arrange | positioned so that it may become horizontal. In addition, a well-known thing can be used for the structure by which the armrest main body 111 is pivotally supported by the stay 112. In addition, when the armrest A2 is in use, the rear end of the armrest body 111 is not tilted downward, and a biasing member such as a spring (not shown) provided on the armrest A2 or a rotation stopper is used to rotate the armrest body 111. Rotation is regulated.

  A locking hole 112a is formed at the lower end of the stay 112, and the stay 112 is pivotally supported by the seat cushion S2 by the shaft member 13 as in the above embodiment. Note that the configuration for restricting the rotation of the stay 112 when the armrest A2 is used is the same as in the above embodiment.

  When the armrest A2 is stored, the armrest body 111 and the stay 112 can be folded as shown in FIG. 6B. At this time, the armrest A <b> 2 is folded so that the side surface 111 a of the armrest main body 111 pivotally supported on the stay 112 via the support shaft 15 extends along the stay 112.

Hereinafter, the operation when the armrest A2 is stored will be described. Note that the reverse operation is performed to return the armrest A2 from the stored state to the used state.
When the armrest A2 is stored, as shown in FIG. 7A, the stay 112 rotates forward and rotates until the stay 112 reaches a predetermined position (substantially horizontal). At this time, forward rotation of the stay 112 is restricted by a rotation stopper (not shown), and the forward rotation of the stay 112 is stopped.

Then, as shown in FIG. 7B, the armrest body 111 rotates rearward along the stay 112 using the support shaft 15 as a rotation axis. That is, as shown in FIG. 7C, the longitudinal direction of the armrest body 111 is in a state along the longitudinal direction of the stay 112 (the state of FIG. 6B). With such a configuration, when the armrest A2 is stored, the armrest main body 111 is disposed along the side surface of the seat cushion S2, so that the storage performance is high.
Since the support shaft 15 functions as a rotating shaft of the armrest body 111 and a function as a slide mechanism, it can save space and is particularly suitable.
The rotation and sliding order of the armrest body 111 and the stay 112 are not limited to the above, and can be arbitrarily set.

  In addition, since the armrest body 111 is folded with respect to the stay 112, the armrest body 111 does not protrude upward during storage even when the length of the armrest body 111 is increased. Therefore, the length of the armrest body 11 is not limited, and a sufficient range for placing the occupant's arms can be ensured, so that the vehicle seat S with good seating property can be obtained.

  Furthermore, since the armrest main body 111 can be arbitrarily rotated with respect to the stay 112, the armrest body 111b of the armrest main body 111 can always be held horizontally without depending on the angle of the stay 112. Accordingly, the height of the armrest surface 111b can be set as appropriate.

(Embodiment 3)
Next, the armrest A3 according to the third embodiment will be described below with reference to FIGS.
The vehicle seat S including the armrest A3 according to the third embodiment is characterized in that the vehicle seat S includes a stay 212 having a configuration different from that of the armrest A2 according to the above-described embodiment. In addition, since the other structure is common in the vehicle seat S of the said embodiment, the description is abbreviate | omitted.

The armrest A3 according to the third embodiment is characterized in that a through hole 212b provided in the stay 212 has a substantially long hole shape in a plan view, and the armrest body 211 is slidable along the longitudinal direction of the stay 212. .
The stay 212 is formed with an elongated through hole 212b having a long axis along the longitudinal direction thereof. The through hole 212b is formed above the locking hole 212a formed in the stay 212 when the armrest A3 is in use. Further, the length of the through hole 212b in the minor axis direction is formed to be at least larger than the diameter of the support shaft 15, and the support shaft 15 can slide along the through hole 212b. The seat cushion S2 or the armrest A3 is provided with a slide stopper (not shown) so that the support shaft 15 (armrest main body 111) does not slide downward when the armrest A3 is in use.

  One end of the support shaft 15 is inserted into a through hole 212 b formed in the upper end portion of the stay 212, and the armrest body 211 is pivotally supported so as to be rotatable with respect to the stay 212. More specifically, when the armrest A3 is in use, the support shaft 15 is inserted through the front end of the armrest body 212, and is inserted through the upper end portion of the stay 212 and is supported by the shaft.

  At this time, the support shaft 15 is inserted from the side surface 211a (surface on the seat cushion S2 side) side of the armrest body 211, and the longitudinal direction of the armrest body 111 and the longitudinal direction of the stay 212 are substantially orthogonal.

When the armrest A4 is in use, the locking hole 312a is formed as a long hole that opens from the lower end portion of the stay 312 to substantially above the central portion.
Further, the length of the locking hole 312a in the minor axis direction is formed to be at least larger than the diameter of the shaft member 13 provided for locking to the seat cushion S2, and the shaft member 13 extends along the locking hole 312a. And can slide. The seat cushion S2 or the armrest A4 is provided with a slide stopper (not shown) so that the stay 312 does not slide downward along the shaft member 13 when the armrest A4 is in use.

The shaft member 13 is inserted into the locking hole 312a, and the stay 312 is pivotally supported so as to be rotatable with respect to the seat cushion S2. More specifically, when the armrest A4 is in use, the shaft member 13 is inserted in the lowermost portion of the locking hole 312a of the stay 312 and the stay 312 is pivotally supported with respect to the seat cushion S2. .
Note that the configuration for restricting the rotation of the stay 312 when the armrest A4 is used is the same as in the above embodiment.

  The armrest body 311 is pivotally supported so as to be rotatable with respect to the stay 312, and the configuration thereof is the same as the armrests A2 and A3 of the above embodiment.

Hereinafter, the operation when the armrest A4 is stored will be described. Note that the reverse operation is performed to return the armrest A4 from the housed state to the used state.
When the armrest A4 is stored, as shown in FIG. 11A, the stay 312 rotates forward, and the stay 212 rotates until it reaches a predetermined position (substantially horizontal). At this time, the rotation of the stay 312 is restricted by a rotation stopper (not shown), and the forward rotation of the stay 312 is stopped.

  As shown in FIG. 11B, the armrest body 311 rotates forward along the stay 312 with the support shaft 15 as a rotation axis. That is, the longitudinal direction of the armrest body 311 is in a state along the longitudinal direction of the stay 312. Then, the armrest body 211 is fixed by the rotation stopper so that the armrest body 211 does not further rotate downward.

Further, when the slide stopper is released, as shown in FIG. 11C, the shaft member 13 slides along the locking hole 312a, so that the stay 312 slides toward the rear of the seat cushion S2. The armrest body 311 and the stay 312 are fixed to the slide stopper in a state where the armrest body 311 and the stay 312 are slid rearward.
