Can.

  The second invention has the following configuration in the first invention described above. The operation target is a release mechanism for releasing the position fixing state of the seat structure attached with the armrest. The operating direction of the armrest for transmitting the amount of movement to the release mechanism is the same as the direction in which the release mechanism is released by the transmission of the amount of movement and the sheet structure can be moved.

  According to the second aspect of the invention, since the movement direction of the armrest is the same as the movement direction of the seat structure, the operation of moving the seat structure can be easily performed.

  The third invention is the following configuration in the first or second invention described above. The armrest is connected so as to be able to rotate up and down between an upright position at which it is not used at the side of the seatback and a forwardly inclined position where it is in use. The operation mechanism has a switching structure that disables transmission of the movement amount of the armrest to the operation target when the armrest is not in use and enables transmission of the movement amount of the armrest to the operation target when the armrest is in use. There is.

  According to the third aspect of the present invention, it is possible to prevent erroneous operation so that the operation target is not erroneously operated even if the armrest is moved in the non-use state of the armrest.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<Basic structure of sheet 1>
First, the configuration of the seat 1 (seat for a vehicle) according to the first embodiment will be described with reference to FIGS. First, the basic configuration of the seat 1 will be described with reference to FIGS. 1 to 6. The seat 1 of the present embodiment is configured as the right-hand seat of the second row of a car provided with three-row seats. As shown in FIG. 2, the seat 1 includes a seat back 2 serving as a backrest of a seated person, a seat cushion 3 serving as a seating portion, a headrest 4 serving as a head rest, and an arm rest 10 serving as an elbow rest. It has a built-in configuration.

<Seat back 2>
The above-described seat back 2 is connected to the rear end portion of the seat cushion 3 via a pair of left and right recliners 5 so that the backrest angle can be adjusted. The respective recliners 5 are normally held in a locked state in which the backrest angle of the seat back 2 is fixed. Each recliner 5 is unlocked at the same time by the operation of pulling up the reclining lever 5A provided on the side outside the vehicle facing the passenger door (not shown) side of the seat cushion 3, and the seat back is released simultaneously. It can be switched to a state in which the backrest angle of 2 can be adjusted.

  By the above switching, the seat back 2 is brought down to a forwardly inclined position shown in FIG. 4 by the biasing force of a spring (not shown) engaged with the seat cushion 3 and a stopper structure (not shown). It is locked by the contact of the At that time, the interior structure is configured such that each recliner 5 holds the released state of the lock even when the operation of the reclining lever 5A is released by the seat back 2 being lowered to the area on the front side of the upright posture. It has been turned down to the position where it is in the forward-tilted position mentioned above. In addition, as shown in FIG. 2, when the seat back 2 is in the rear side area from the upright posture, each recliner 5 is returned to the locked state by the bias when the operation of the reclining lever 5A is released. ing.

  Therefore, after the seat back 2 is lowered to the forwardly inclined position shown in FIG. 4, the seat back 2 is pushed backward without requiring the operation of the reclining lever 5A. It is raised to the rear side at. As shown in FIG. 5, the lift of the seat back 2 is raised to a position where the seat back 2 is in the upright position, whereby each recliner 5 is locked by biasing and returned to the upright position. It is locked in position.

<Seat cushion 3>
As shown in FIG. 3, the seat cushion 3 is connected on the floor of the vehicle in a state where position adjustment can be performed in the front-rear direction via a pair of left and right slide rails 6. The slide rails 6 are normally held in a state of being switched to the slide lock state in which the position of the seat cushion 3 is fixed. When the slide levers 6A provided on the front lower portion of the seat cushion 3 are pulled up, the slide lock states of the slide rails 6 are simultaneously released, and the front-rear position of the seat cushion 3 can be adjusted. It is possible to switch to. Each slide rail 6 is returned to the locked state by biasing when the operation of the slide lever 6A is released.

  Further, the slide lock 6 is released from the slide lock state by the operation of a cable (not shown) which picks up the movement even when the seat back 2 mentioned above in FIG. It is supposed to be. When the slide lock is released by the front fall of the seatback 2, the slide rails 6 continue the operation of the cable (not shown) while the seatback 2 is locked in the forward inclined position. In order to hold the slide lock released.

<Walk-in operation of sheet 1>
The seat 1 can be retracted to the front side by switching the seat back 2 to the forward inclined posture by a mechanism in which the slide lock state of each slide rail 6 is released in conjunction with the front fall of the seat back 2 It is configured to have a walk-in function. That is, when the user gets on and off the third row seat (not shown) from the passenger door (not shown) outside the vehicle of the seat 1, the seat 1 retracts forward by the walk-in function As a result, it is possible to secure a wide area for getting on and off.

  After the seat 1 is retracted to the front side by the walk-in function, as shown in FIG. By raising the seat back 2 to the rear side, it is returned to the initial position before the above-described retraction operation. However, when the seat 1 is operated to be pushed back to the initial position, the seat back 2 is pushed back to the upright posture prior to the rear slide of the seat 1 by the backward pressure applied to the seat back 2. In addition, the slide rails 6 are slide-locked and the position is fixed without sufficient backward movement.

  In such a case, the seat 1 can be moved to the rear side again by switching the seat 1 back to the forward tilt position by operating the reclining lever 5A or switching to the slidable state by operating the slide lever 6A. It can be done. However, in any case, the user bends the waist from the position where it stands on the outside of the passenger door (not shown), and reaches the reclining lever 5A and the slide lever 6A in the low position of the seat 1 Operation is not good.

  Furthermore, when the reclining lever 5A is operated, the seat back 2 is carefully pushed backward to prevent the seat back 2 from being pushed back again in the upright posture again, or the seat in the low position not to do so. The cushion 3 has to be pushed and moved. Further, when the slide lever 6A is operated, the seat 1 has to be pushed backward while maintaining the operation state in which the slide lever 6A is pulled up.

<Amrest 10>
Therefore, in the present embodiment, as shown in FIG. 6, the arm rest 10 provided on the seat back 2 is provided with a function capable of releasing the slide lock state of each slide rail 6. As shown in FIG. 1, the armrest 10 can be turned up and down by a support shaft 11 whose axis is directed in the width direction to the side of the vehicle outer side facing the passenger door (not shown) side of the seatback 2. It is connected. By the above connection, the armrest 10 is turned forward to a substantially horizontal angle state toward the front side of the seatback 2 and the upright position (see FIG. 7) raised up along the side shape of the seatback 2 It is in a state where it can be rotated up and down between the forwardly inclined position (see FIG. 8). The armrest 10 is brought into contact with a stopper structure (not shown) formed between the seatback 2 at respective positions rotated to the upright position (see FIG. 7) and the forwardly inclined position (see FIG. 8). It is supposed to be locked.

  Specifically, the armrest 10 described above is connected to the support shaft 11 described above so as to be slid backward as shown in FIG. 9 by being tilted to the front tilt position as shown in FIG. It is in the state. The armrest 10 pushes and moves the operation mechanism 20 provided between the armrest 10 and the seat back 2 by the slide to the rear side, thereby releasing the slide lock state of each slide rail 6 to the release mechanism 6B. By transmitting the operation movement amount, the slide lock state of each slide rail 6 is released.

  Therefore, as shown in FIG. 1, with the normal sitting posture in which the user is seated on the seat 1, the armrest 10 can be used as an elbow rest by lowering the armrest 10 to the front tilt position. The slide lock state of each slide rail 6 can be easily released by sliding the armrest 10 rearward by pulling the elbow placed on the rear side or the like. That is, even if the user does not operate the slide lever 6A as described above with reference to FIG. 3 from the posture in which the user is seated on the seat 1, the simple operation of pulling the armrest 10 to the rear side Thus, the slide lock state of each slide rail 6 can be released.

  By providing such an operation structure on the armrest 10, the seatback 2 is raised when pushing back the seat 1 from the state of being retracted forward by the walk-in function as described above with reference to FIG. Even if each slide rail 6 is locked in the middle of the rear slide by raising first, as shown in FIG. 6, the arm rest 10 is tilted to the forward tilt position to slide the slide rail 6 backward. The slide lock state can be released easily, and the movement of the seat 1 to the rear side can be resumed.

  More specifically, the operation of sliding the armrest 10 rearward moves the armrest 10 at a position higher than the seat cushion 3 from the position where the user stands on the outside of the passenger door (not shown) outside the vehicle. It can be performed by a simple operation that does not bend the body forward, such as turning it down and pushing it backward. In addition, the operation of pushing the armrest 10 rearward is such that the user leans backward on the armrest 10 located at a position higher than the seat cushion 3 from the position where the user stands outside the passenger door (not shown). It can be done easily. Furthermore, even after the armrest 10 is slid rearward to release the slide lock state of each slide rail 6, the armrest 10 continues to be applied with a pressing force to the rear side, thereby setting the armrest 10 as a force point. It is also possible to perform an operation of pushing 1 back as it is.

<Mounting structure of armrest 10>
Hereinafter, the specific structure of the attachment structure to the seat back 2 of the armrest 10 mentioned above, and the operation mechanism 20 operated by backward movement of the armrest 10 will be described. As shown in FIGS. 8 and 11, the armrest 10 has its root portion welded to the outer side of the side frame 2A on the vehicle outer side of the seatback 2, and the outer side of the support bracket 2B overhangs in a hat shape on the vehicle outer side. It is put on the part, and it is made to be in the state where it was rotatably connected by the spindle 11 inserted from the vehicle outer side with respect to the overhanging outside part of the support bracket 2B.

  Specifically, the armrest 10 has a state in which the round bar-like shaft portion of the support shaft 11 is inserted into the long hole 12 penetrating in the width direction formed at the root portion and connected to the outer side portion of the support bracket 2B. It is done. The long hole 12 is formed in a hole shape extending linearly in a longitudinal direction in the longitudinal direction from the root side to the tip side of the armrest 10. Therefore, the armrest 10 is supported between the range in which each end in the longitudinal direction of the long hole 12 abuts on the round rod portion of the support shaft 11 by the connection to the support bracket 2B via the support shaft 11 It will be in the state assembled | attached in the state slid to a longitudinal direction with respect to the bracket 2B. Strictly speaking, as shown in FIG. 9, the rear slide of the armrest 10 can be performed to a position where the leaf spring 13 interposed between the end of the long hole 12 on the tip end side and the support shaft 11 is crushed. It has become.

  The armrest 10 is constantly pushed outward from the support shaft 11 in the radial direction by the biasing force of the plate spring 13 assembled between the support shaft 11 and the support shaft 11, as shown in FIGS. As a result, the end of the long hole 12 on the root side is held in a state of being pressed against the support shaft 11. The plate spring 13 is provided in the long hole 12 of the armrest 10, and a repulsive force in the direction of pulling away each other acts between the end of the long hole 12 on the tip end side and the support shaft 11 It is assembled.

  Due to the biasing force of the leaf spring 13, the armrest 10 is normally raised relative to the seat back 2 centering on the support shaft 11 in a state where the end on the root side of the long hole 12 is pressed against the support shaft 11. It is in an elastically supported state so as to be able to turn over (see FIGS. 7 to 8). Then, the armrest 10 is pushed back by the user from the state in which the armrest 10 is tilted down to the front tilt position shown in FIG. 8, thereby resisting the biasing force of the leaf spring 13 as shown in FIG. It is designed to be pushed backward.

<Operation mechanism 20>
As shown in FIGS. 8 and 11, the operating mechanism 20 includes an operating pin 21 attached to the inner side of the armrest 10, an operating body 22 attached to the outer side of the support bracket 2B, and the operating body 22 and FIG. And the cable 23 connected between the release mechanism 6B of each slide rail 6 described above. As shown in FIG. 8, the operation pin 21 is provided at a position on an extension of the above-described elongated hole 12 on the extending end side, with the axis directed in the width direction. The operating body 22 includes a base 22A fixed to the outer side of the support bracket 2B, and a slider 22B assembled so as to be slidable only in the height direction with respect to the base 22A. ing.

  The upper end portion of the cable 23 is connected to the lower end portion of the slider 22B so that the operation movement amount can be transmitted to the release mechanism 6B of each slide rail 6 described above with reference to FIG. It is connected. As shown in FIG. 10, in the slider 22B, the release mechanism 6B connected to the other end of the above-mentioned cable 23 is constantly held against the base 22A by a force that is elastically held at the initial position by biasing. And is locked at a position where it slides downward. In the state of the initial position, the slider 22B is located between the arrangement of the operation pin 21 and the long hole 12 and is tapered downward on the side surface facing the operation pin 21. The inclined inclined surface 22 </ b> C is arranged at a position facing the operation pin 21.

  As shown in FIG. 9, the slider 22B is pushed rearward by the operating pin 21 from the state in which the armrest 10 is in the front-tilt position and the inclined surface 22C is pushed rearward by the operation pin 21 and moves upward. It is pushed up. By this operation, the cable 23 connected to the slider 22B is pulled upward, and the release mechanism 6B of each slide rail 6 described in FIG. 1 connected to the other end side of the cable 23 releases the slide lock state It is operated to do.

  In the operation mechanism 20 described above, as shown in FIG. 8, when the armrest 10 is in the state of being tilted forward, as shown in FIG. 9, the armrest 10 resists the biasing force of the plate spring 13 and moves backward. Although the cable 23 is pulled by the force to be pushed, even when the armrest 10 is raised to the upright position as shown in FIG. 7, even if the armrest 10 is pushed against the biasing force of the leaf spring 13 The switching structure 20A is provided so as not to pull the cable 23. In the switching structure 20A, the operating pin 21 and the operating body 22 operated by the operating pin 21 are provided separately for the armrest 10 and the support bracket 2B, and the armrest 10 is in the upright position as shown in FIG. By raising the operating pin 21 and the operating body 22 in a circumferentially separated state, the operating pin 21 is not pressed against the operating body 22 even when the armrest 10 is operated It has a simple configuration that can be switched to

<Summary>
Summarizing the above, the seat 1 of the present embodiment is configured as follows. That is, the operation member for transmitting the amount of operation movement to the release mechanism 6B (the operation target) is configured by the movable armrest 10. With such a configuration, it is rational to use the movable structure of the armrest 10 without separately providing an operating member for transmitting the amount of operation movement to the releasing mechanism 6B by a lever or the like of another member. Can be configured.

  Further, the release mechanism 6B described above is a mechanism for releasing the slide lock state of each slide rail 6 (the position fixing state of the sheet structure attached with the armrest 10). The operating direction of the armrest 10 for transmitting the movement amount to the release mechanism 6B is the same as the movement direction (backward direction) of the seat 1 which allows the release mechanism 6B to be released and moved by the transmission of the movement amount. It has become. With such a configuration, the movement direction of the armrest 10 is the same as the movement direction of the seat 1, so that the operation of moving the seat 1 can be easily performed.

  In addition, the armrest 10 is connected so as to be able to rotate up and down between the upright position (see FIG. 7) in the unused state on the side of the seatback 2 (see FIG. 7) and the forwardly inclined position (see FIG. 8) in the use state. It is done. The operating mechanism 20 disables transmission of the movement amount of movement of the armrest 10 to the release mechanism 6B when the armrest 10 is not in use (see FIG. 7), and moves movement of the armrest 10 when the armrest 10 is in use (see FIG. 8). A switching arrangement 20A is provided which enables the transfer of the quantity to the release mechanism 6B. With such a configuration, erroneous operation can be prevented so that the release mechanism 6B is not erroneously operated even when the armrest 10 is moved in a non-use state of the armrest 10.

  Then, the structure of the sheet | seat 1 of Example 2 is demonstrated using FIGS. 12-13. In this embodiment, when the armrest 10 is raised to the upright position, the operation movement amount is transmitted to the release mechanism 6B for releasing the slide lock state of each slide rail 6 by turning it further to the rear side. As a result, the slide lock state of each slide rail 6 is released. Unlike the configuration shown in the first embodiment, the armrest 10 is raised from the front tilt position to the upright position, whereby a spring (not shown) attached to the support bracket 2B is pressed from the side to be constant at the upright position. It is designed to be held in a state where moderation is given. However, the armrest 10 is rotated from the upright position to a position to be pushed backward by the user by operating the armrest 10 further backward against the biasing force of the spring (not shown). It is supposed to be The armrest 10 is locked by the abutment of a stopper structure (not shown) at a position where the armrest 10 is pushed and inclined to the rear side by a fixed amount from the standing position.

  By the above operation, as shown in FIG. 13, the operating pin 21 attached to the armrest 10 pushes and moves the slider 22B of the operating body 22 attached to the support bracket 2B to pull the cable 23, thereby releasing the release mechanism 6B. The slide lock state of each slide rail 6 is released through the operation of. The series of operation structure of the operation mechanism 20 in which the operation pin 21 pushes and moves the slider 22B of the operation body 22 by the operation of pushing the armrest 10 to pull the cable 23 is the same as the operation mechanism 20 shown in the first embodiment. It has the composition of

  Then, after the slide lock state of each slide rail 6 is released by the backward rotation from the standing position of the armrest 10, the pressing force toward the rear side is continuously applied to the armrest 10 to make the armrest 10 a force point. It can push and move 1 as it is backward. The above-described operation structure may be provided instead of the operation structure in which the slide lock state of each slide rail 6 is released by pushing and moving the armrest 10 from the front tilt position to the rear side as described in the first embodiment. It may be provided additionally to the operation structure shown in the first embodiment. The configuration other than the above is the same as the configuration of the seat 1 shown in the first embodiment, so the same reference numerals are given and the description is omitted.

  As mentioned above, although embodiment of this invention was described using two Examples, this invention can be implemented with various forms other than the said Example. For example, the vehicle seat of the present invention can be applied to a seat other than the rear seat of a car, or may be a seat applied to a vehicle other than a car such as a railway, or an aircraft or a ship It can be widely applied to seats provided for various vehicles such as, etc.

  Also, the armrest may be of a type configured to be provided so as to be developed and accommodated so as to be able to be stored in a part of a seatback of a so-called bench seat. Also, the armrest may be of a type configured to be provided on a console installed on the side of the seat. The armrests may be provided on both the left and right sides of the seat, and one or both of them may be configured to transmit the amount of movement to the operation target.

  The operation target is a mechanism for releasing the slide lock state of the slide rail, a mechanism for releasing the fixed state of the usage angle of the ottoman, and an operation for releasing the fixed state of the backrest angle by the recliner. For example, it may be a mechanism such as a mechanism for releasing any position fixing state of the sheet structure. Moreover, the operation target is not limited to the release mechanism as described above, but the strength of the tension of the wire is changed by receiving the transmission of the movement movement amount from the armrest, and the strength of the supporting force of some support structure such as lumber support is It may be configured as an adjustment mechanism to be adjusted, or a movement mechanism that changes the position of any accessory by transmission of the movement movement amount.
