  In the above prior art, the memory member that slides and guides the memory member is configured to be held in a state where the memory rail is engaged by the spring biasing force in the push-up direction, and thus the release operation by pushing down the memory member is appropriately performed. In order to do so, it is necessary to devise measures to prevent foreign substances such as sand from entering under the memory member. The present invention was devised as a solution to the above problem, and the problem to be solved by the present invention is that foreign matter such as gravel enters under the memory member that stores the position before the change of the seat position. It is to prevent this appropriately.

  In order to solve the above problems, the vehicle slide rail device of the present invention takes the following means.

  According to a first aspect of the present invention, there is provided a memory including a slide rail capable of adjusting a seat position by a release operation of a lock mechanism, and a memory member capable of storing a position before the seat position is changed by mechanical engagement with the slide rail. A vehicle slide rail device that operates to return the seat position to the pre-change storage position upon contact with the member, and further releases the lock mechanism from the locked state and stores the memory member in the position storage state. And a release operation mechanism that is operated so as to be pulled in the slide direction in which the seat position is adjusted. The memory mechanism includes a leaf spring that is engaged in a state in which the memory member is urged in the direction of pushing up the memory member from below and is stored in the position of the slide rail. The memory member has a pair of bottom portions in the width direction that restricts the maximum depressed position by the release operation mechanism by bottoming. A lower support portion that a leaf spring is applied to the bottom surface of the memory member, and a leg portion that extends from the lower support portion to a position exceeding the pair of bottom portions in the width direction in the sliding direction and elastically supports the lower support portion from below. And a wide grounding portion projecting in a shape extending in the width direction rather than the inner diameter between the pair of bottom portions in the width direction in the ground contact region of the leg portion.

  According to the first aspect of the present invention, the wide grounding portion projecting in the width direction from the grounding region of the leg portion of the leaf spring allows the grounding region of the leg portion to be widened without hindering bottoming of the bottomed portion of the memory member. It is possible to appropriately prevent foreign matter such as gravel from entering under the memory member.

  The second invention is the following configuration in the first invention described above. The leaf spring has a wide grounding portion at a position beyond the memory member in the sliding direction.

  According to the second aspect of the invention, the wide grounding portion of the leaf spring can be provided in such a form that it is more difficult to inhibit the bottoming of the pair of bottomed portions of the memory member.

  The third invention is the following configuration in the first or second invention described above. The wide grounding portion has a standing wall that rises so that the surface faces in the sliding direction.

  According to the third aspect of the invention, since the wide grounding portion has the standing wall, it is possible to more appropriately prevent foreign matter such as gravel from entering under the memory member.

  According to a fourth invention, in any one of the first to third inventions described above, the following configuration is adopted. On the other hand, the leaf spring has a structure in which a leg portion and a pair of wide grounding portions corresponding to the leg portion are provided at each position beyond the memory member in the sliding direction to support the lower support portion symmetrically in the sliding direction. The members have an asymmetric structure in which the extension lengths in the sliding directions from the lower support portions are different from each other. The wide grounding portion provided on the short extension side of the memory member has a longer projecting surface region that projects to cover the gap with the memory member than the wide grounding portion on the other side.

  According to the fourth aspect of the invention, the memory member can be elastically supported in a well-balanced manner by each leg portion of the leaf spring having a symmetrical structure, and the gap between the leaf spring and the memory member is widened. The overhanging surface region formed on the leg can appropriately prevent foreign matter such as gravel from entering under the memory member from these gaps.

  According to a fifth invention, in any of the first to fourth inventions described above, the following configuration is adopted. The leaf spring has a pair of leg portions and wide grounding portions corresponding to the leg portions at each position beyond the memory member in the sliding direction. The wide grounding portion provided on the side to which the link member is applied to return the seat position from one side in the sliding direction with respect to the memory member has a lower rise from the grounding surface than the wide grounding portion on the other side.

  According to the fifth aspect of the present invention, even if the wide grounding portion of the leaf spring is provided at the position where the link member of the memory member is applied, the movement of the link member hitting the memory member can be hardly inhibited.

  A sixth invention is the following configuration in any of the first to fifth inventions described above. The wide grounding part consists of the leaf spring itself.

  According to the sixth aspect of the invention, the wide grounding portion can be easily formed by forming the leaf spring.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.

<< General structure of slide rail device M >>
First, the configuration of the seat 1 to which the slide rail device M (vehicle slide rail device) according to the first embodiment is applied will be described with reference to FIGS. As shown in FIG. 1, the seat 1 of this embodiment is configured as a driver seat of a right-hand drive vehicle. The seat 1 includes a seat back 2 that serves as a backrest portion for a seated occupant, a seat cushion 3 that serves as a seating portion, and a headrest 4 that serves as a headrest portion.

  The seat cushion 3 described above is connected to the floor F of the vehicle via a pair of left and right slide rails 10 constituting the slide rail device M described above. The seat back 2 is connected to the rear end portion of the seat cushion 3 described above via a pair of left and right recliners (not shown). The headrest 4 is mounted on the upper portion of the seat back 2.

  In the following description, when directions such as front / rear, up / down, left / right, and the like are indicated, the directions shown in the drawings are indicated. Further, the term “seat width direction” refers to the lateral width direction (left-right direction) of the seat 1, and the term “vehicle width direction” refers to the lateral width direction (left-right direction) of the vehicle. That is, the term “inner side in the vehicle width direction” refers to the left side of the seat 1, that is, the side with the passenger seat (not shown) (inner), and the term “outer side in the vehicle width direction” refers to the right side of the seat 1; That is, it points to the side (outer) on which a passenger door (not shown) is present.

  In the initial state, the above-described seat 1 is in a state in which the position of the front-rear direction on the floor F (hereinafter referred to as “seat position”) is fixed as the slide of each slide rail 10 is locked by urging. Is held in. As shown in FIG. 2, the slide rails 10 described above are released from the slide-locked state all at once by the operation of pulling up the loop handle 5 provided at the front lower portion of the seat cushion 3 by the user. Thus, the seat position can be switched to a state in which the seat position can be freely adjusted in the front-rear direction. Each slide rail 10 is returned to the state where the slide is locked again at that position by returning the operation of the loop handle 5 after adjusting the seat position.

  Further, as shown in FIG. 1, each of the slide rails 10 described above can also be operated by an operation in which the passenger is lifted by the user with the passenger lever 6 provided on the outer side (right side) of the seat cushion 3 in the vehicle width direction. The slide-locked state is released all at once (circled number 1). Each slide rail 10 is lowered by moving the seat position to the rear side while maintaining the operation state of the above-described entry / exit lever 6, so that the operation of the operation mechanism 30 provided in the slide rail device M, which will be described later, The movement of the seat back 2 is locked when the seat back 2 is pulled down to the boarding / alighting support position in the vicinity of the rearmost where the B pillar BP of the vehicle substantially overlaps the position in the front-rear direction (circled number 2).

  Specifically, each of the slide rails 10 described above is slide-locked at that position even when the operation state of the above-described entry / exit lever 6 is maintained by lowering the seat position to the above-described entry / exit support position near the rearmost. It is possible to switch to the set state. Therefore, the seat position is pulled down to the rear side while the passenger lever 6 is operated, and the movement is stopped, so that the seat position reaches the passenger support position in the vicinity of the rearmost, and a wide passenger space is obtained. The user can be made aware that the state has been switched to the secured state.

  In addition, each slide rail 10 described above is operated again so that the user can lift the passenger lever 6 again from the state where the seat position is lowered to the passenger support position near the rearmost as described above. These slide-locked states are released all at once (circled number 3). Each slide rail 10 moves the seat position to the front side while maintaining the above-described operation state of the passenger lever 6, so that the seat position is lowered to the rear side by the operation of the operation mechanism 30 described above. These slides are returned to the locked state when they reach the initial position before being moved, that is, the position at which the passenger lever 6 is operated and lowered to the rear side (circled number 4). .

  That is, the slide rail device M can store the position of the seat position when the passenger lever 6 is operated when the passenger lever 6 is operated and the seat position is changed. By changing the seat position back to the original position, when the seat position reaches the memorized position, the slide position is switched to the locked position, and the seat position is changed to the memory position before the change. It can be easily restored. Therefore, after a person sits on the seat 1 at the above-described getting-on / off support position near the rearmost, the person operates the getting-on / off lever 6 again to move the seat position toward the front side while maintaining the operation state. As a result, it is possible to return the seat position to the pre-change storage position all at once and return to the state locked at that position.

  As shown in FIG. 3, each of the slide rails 10 described above is configured such that the operation state of the above-described entry / exit lever 6 is solved at an intermediate position between the storage position before change described above with reference to FIG. 1 and the entry / exit support position near the rearmost. In the case where it is released, it can be switched to a slide-locked state at an arbitrary position where it is unwound. Each slide rail 10 is again operated at the above-described slide-locked arbitrary position, and the operation of the getting-on / off lever 6 is performed again, so that the seat position is again changed to the storage position before change described above with reference to FIG. It can be switched to a state that can be freely adjusted between positions. Then, each slide rail 10 is slide-locked at the same position by moving the seat position to the pre-change storage position described above with reference to FIG. 1 while maintaining the above-described operation state of the passenger lever 6. It is supposed to be returned to.

<< Specific structure of slide rail 10 >>
Hereinafter, a specific configuration of each of the pair of left and right slide rails 10, the memory mechanism 20, and the operation mechanism 30 constituting the slide rail device M will be described in detail. First, the configuration of each slide rail 10 will be described with reference to FIGS. That is, each slide rail 10 is assembled with a lower rail 11 attached on the floor F, an upper rail 12 attached to the lower portion of the seat cushion 3 and assembled with the lower rail 11 so as to be slidable in the front-rear direction. And a lock spring 13 that locks the slide between the rails 11 and 12. Since the basic structure of each slide rail 10 is substantially the same configuration on the left and right, the detailed configuration of the slide rail 10 is a slide disposed on the inner side (left side) in the vehicle width direction shown in FIG. A description will be given by using the configuration of the rail 10 as a representative. Here, the lock spring 13 described above corresponds to the “lock mechanism” of the present invention.

  As shown in FIG. 5, the lower rail 11 described above is formed by bending a sheet of steel or the like that is elongated in the longitudinal direction of the vehicle into a substantially U shape in the lateral direction. The lower rail 11 described above has its front and rear end portions fastened and fixed integrally on the floor F by a fastening structure such as a bolt (not shown). The lower rail 11 described above is formed in a rail shape whose cross-sectional shape is substantially uniform in the front-rear direction.

  Specifically, the lower rail 11 described above has a bottom surface portion 11A set on the floor F with its surface facing upward, and extends upward from the left and right edges of the bottom surface portion 11A toward the inward sides of each other. Thus, it is formed in a cross-sectional shape having a pair of left and right lower fin portions 11B which are bent and extended in an inverted U shape. The lower rail 11 described above is set in a state in which the end portions on the front and rear sides of the bottom surface portion 11A described above are in surface contact with the floor F from the upper side, and are not illustrated bolts inserted into the respective portions from the upper side. It is set as the state fastened integrally on the floor F by fastening structures, such as.

  In the left and right lower fin portions 11B of the lower rail 11 described above, respective lock portions 13C corresponding to lock springs 13 to be described later are respectively provided from the lower side at the respective edge portions bent back in an inverted U shape. A lock groove 11C that can be inserted and engaged is formed. Each of these lock grooves 11C is formed in a shape of opening downward along the respective edge portions that are folded down and hung inside the respective lower fin portions 11B, and a plurality of these are arranged at equal intervals in the front-rear direction. It has been formed. The lock grooves 11C formed in the lower fin portions 11B are formed side by side at symmetrical positions.

  In addition, the left and right lower fin portions 11B of the lower rail 11 described above are slid in the front-rear direction of the upper rail 12 respectively in the vicinity of the front end portion and the vicinity of the rear end portion of each side surface portion rising from the bottom surface portion 11A. The locking claws 11D and 11E that restrict the contact by contact are formed in a shape that is obliquely raised and raised inward. These locking claws 11D and 11E are cut and raised after the upper rail 12 is inserted into the above-described lower rail 11, and the front and rear locking claws 12D formed on the upper rail 12 are made to slide in the front-rear direction of the upper rail 12. And abutment with the rear locking claw 12E.

  Each locking claw 11 </ b> D on the front end side formed on the lower rail 11 described above is formed at a position farther to the front side than each locking groove 11 </ b> C on the front end side formed on the lower rail 11. Further, the rear end side locking claws 11 </ b> E formed on the lower rail 11 described above are formed at positions farther rearward than the rear end side locking grooves 11 </ b> C formed on the lower rail 11. With such an arrangement relationship, the lower rail 11 locks the slide of the upper rail 12 described above in the lock region A1 (see FIG. 34) in which the lock grooves 11C described above are arranged in the front-rear direction. The slide itself is allowed to allow each overstroke area A2 (see FIG. 34) beyond the lock area A1 in the front-rear direction.

  Similar to the lower rail 11 described above, the upper rail 12 is formed by bending a sheet of steel or the like that is elongated in the longitudinal direction of the vehicle into a substantially Ω-shaped shape in the lateral direction. The above-described upper rail 12 is assembled into a state in which the upper rail 12 is slidable in the longitudinal direction with respect to the lower rail 11 by being inserted into the lower rail 11 from the opening end portion on either side in the longitudinal direction of the lower rail 11 described above. ing. Specifically, the upper rail 12 has a cross-sectional shape that is attached to the top of the seat cushion 3 with the surface facing upward on the lower side of the seat cushion 3 and the left and right edges of the top plate 12A. It is formed in the cross-sectional shape which has a left-right paired upper side fin part 12B extended in the U-shape toward the outer side which mutually opposes from the part, and was made into the shape extended. The top plate portion 12A of the upper rail 12 described above is formed with a through hole 12Aa for allowing components of the memory mechanism 20 and the operation mechanism 30 described later to pass in the height direction.

  In the upper rail 12 described above, the respective edge portions of the lower rail 11 bent back in the U-shape of the left and right upper fin portions 12B are inverted U of the left and right lower fin portions 11B of the lower rail 11. It is inserted and assembled in the longitudinal direction so as to engage with each part bent back in a letter shape. By being assembled in this way, the upper rail 12 is positioned in the height direction with respect to the lower rail 11 due to the engagement of the left and right upper fin portions 12B and the lower fin portions 11B. The sheet is assembled in a state of being prevented from coming off in the sheet width direction. Specifically, the above-described upper rail 12 is arranged in the height direction and the seat width direction with respect to the lower rail 11 via a resin shoe and a steel ball (rolling element) (not shown) assembled between the above-described lower rail 11. Each is held in a state of being assembled so that it can slide smoothly in the front-rear direction while being restrained.

  The left and right lock portions 13C of the lock spring 13, which will be described later, extend from the inside to the outside at the center in the front-rear direction of each side surface portion that hangs down from the top plate portion 12A of the left and right upper fin portions 12B of the upper rail 12 described above. A through groove 12C is formed. Further, each of the above-described fin portions bent back in a U shape of each upper fin portion 12B described above has two locations in the front and rear thereof, the vicinity of the front end portion and the vicinity of the rear end portion of the lower rail 11 described above. The locking claws 12D and 12E that are locked to the respective locking claws 11D and 11E formed in the sliding direction are cut and raised upright. These locking claws 12D and 12E are formed separately at respective locations avoiding the through grooves 12C formed at the central portion of the left and right upper fin portions 12B described above.

  The lock spring 13 is formed by bending a single wire such as steel into a substantially U shape in a plan view extending in the longitudinal direction. The lock spring 13 described above has a rear end portion 13B formed as a folded portion that is folded back to the front side in a substantially U shape in plan view. Then, at the middle part of each line part extending from the folded rear end part 13B of the lock spring 13 to the front side as a pair of left and right parts, the part is bent into a wavy shape toward the outside in the sheet width direction. The formed lock portion 13C is formed. Further, the front end portion 13A of each line portion of the lock spring 13 described above is formed into a shape that is bent so as to protrude outward in the sheet width direction.

  In the lock spring 13 described above, the respective front portions of the front end portions 13A of the left and right line portions described above that are bent outward in the seat width direction are standing walls in the front region of the upper fin portions 12B of the upper rail 12 described above. Each of the through holes 12Ba formed in the portion is inserted into the through holes 12Ba while being elastically squeezed from the inside, and is set as a state where the pins are rotatably connected. Further, the above-described lock spring 13 is formed by turning up the folded portions on both corners of the above-described rear end portion 13B inwardly from the standing wall portion of the rear region of each upper-side fin portion 12B of the above-described upper rail 12. The hooks 12Bb are hooked from the upper side and are set so as to be rotatably pin-coupled.

  The above-described lock spring 13 has the above-described left and right lock portions 13C inside each through groove 12C formed at the center in the front-rear direction of the above-described left and right upper fin portions 12B of the upper rail 12, respectively. It is assembled as a state where it is pushed out from the outside while being elastically squeezed. Each of the through grooves 12C described above has a shape having a comb-like slit through which each of the lock portions 13C of the lock spring 13 passed therethrough can be individually elongated toward the upper side.

  As described above, the lock spring 13 is in a free state by having a front end portion 13A and a rear end portion 13B that are pin-connected to the upper rail 12 so as to be rotatable in the height direction. Then, due to the restoring action by its own spring urging force, each lock portion 13C described above is passed from the lower side and the rear side in a state where the lock portion 13C is passed from the lower side into each slit elongated in a comb shape in each through groove 12C of the upper rail 12. It is held in a supported state.

  In the lock spring 13 described above, the slide position of the upper rail 12 in the front-rear direction with respect to the lower rail 11 is changed to each slit in the through groove 12C formed in the upper fin portion 12B on each side and the lower fin portion 11B on each side. By aligning the formed lock grooves 11C with each other in the vehicle width direction, the lock grooves 11C are passed through the slits in the through grooves 12C and the lock grooves 11C from below by a spring biasing force. It has become so.

  As a result, the slide in the front-rear direction with respect to the lower rail 11 of the upper rail 12 is locked and held via the lock portions 13C of the lock spring 13 described above. The state where the slide of the upper rail 12 with respect to the lower rail 11 is locked is shown in FIGS. 13, 14, 18, 19, 22, and 25. It is represented as a state of entering into each lock groove 11C from below.

  The lock spring 13 described above is pushed down by the lock portion 13C when the loop handle 5 described above is operated (see FIGS. 14 to 18) or the passenger lever 6 is operated (FIGS. 19 to 25). It is bent and removed from the lock groove 11 </ b> C of the lower rail 11 downward. Accordingly, the slide lock state of the upper rail 12 via the lock spring 13 is released, and the upper rail 12 can be slid in the front-rear direction with respect to the lower rail 11. Thereafter, when the operation of the operated loop handle 5 or the getting-on / off lever 6 is released, the lock spring 13 enters the lock groove 11C of the lower rail 11 again by the spring biasing force as shown in FIG. The slide is returned to the locked state.

  At that time, when the slide position of the upper rail 12 is in a state where there is no lock groove 11C of the lower rail 11 at the position where the lock portion 13C of the lock spring 13 is restored, that is, the shelf surface between the lock grooves 11C is located. The lock portion 13C is returned only to a position where it comes into contact with the shelf surface, and is not in a slide lock state. However, by shifting the slide position of the upper rail 12 from the slide position to either the front or rear side, the lock portion 13C is aligned with the lock groove 11C of the lower rail 11 and enters the lock groove 11C (slide lock (Status).

  The above is the specific configuration of each slide rail 10 shown in FIG. In addition, a memory mechanism 20 and an operation mechanism 30 (to be described later) are further assembled to the slide rails 10 arranged on the inner side (left side) in the vehicle width direction.

  The stopper bracket 15 described above is configured such that the above-described inner slide rail 10 in the vehicle width direction is unlocked and slides to the rear side, so that the upper edge portion of the standing plate portion is moved outward in the vehicle width direction. The locking surface portion 15A formed in a hook-like shape is applied from the rear side to a trigger link 22A of the memory mechanism 20 to be described later, and the trigger link 22A is pushed forward to operate the entrance / exit lever 6. Accordingly, the unlocking operation state of the slide rail 10 is canceled and the slide rail 10 is locked at that position.

<< Specific Configuration of Memory Mechanism 20 >>
Next, a specific configuration of the memory mechanism 20 will be described. As shown in FIG. 5 to FIG. 7, the memory mechanism 20 is roughly divided into a memory body 21 assembled on the lower rail 11 side serving as the fixed side and the upper rail 12 side serving as the movable side. And a detection operation body 22 assembled in the structure.

  As shown in FIGS. 19 to 22, the former memory body 21 remains at a fixed position on the lower rail 11 and changes the seat position when the seat position is lowered to the rear side by operating the above-described boarding lever 6. It functions as a stationary member that stores the previous position. The latter detection operation body 22 lowers the seat position to the rear side by the operation of the above-described entry / exit lever 6, and then, again, as shown in FIGS. When returning to the remaining storage position 21, the memory body 21 is pressed from the rear side to rotate, and operates to lock the seat position at that position.

<< Specific Configuration of Memory Body 21 >>
Next, a specific configuration of the memory body 21 described above will be described with reference to FIGS. The memory body 21 includes a memory rail 21A extending in a longitudinal direction in the front-rear direction, a memory piece 21B assembled so as to be slidable in the front-rear direction with respect to the memory rail 21A, and the memory rail 21A constantly with respect to the memory piece 21B. And a leaf spring 21C that applies a spring biasing force upward. Here, the memory piece 21B corresponds to the “memory member” of the present invention.

<< Configuration of Memory Rail 21A >>
As shown in FIGS. 5 to 7 and 10, the memory rail 21 </ b> A described above has a thin, substantially box-shaped rail shape in which one sheet of steel or the like extending in the longitudinal direction opens upward. In this way, it is bent in the short direction. Specifically, the memory rail 21 </ b> A has a configuration in which a slit-shaped guide hole 21 </ b> Aa that opens in a straight line shape in the front-rear direction is formed at a central portion in the seat width direction of the top plate portion. . The memory rail 21 </ b> A described above is provided in a state in which the end portions on the front and rear sides thereof are screwed onto the bottom surface portion 11 </ b> A of the lower rail 11 and fixed integrally.

It is formed in the form of multiple lines. Each of the engaging holes 21Ab is fitted with the engaging claws 21Ba2 bent from the lower side so as to protrude upwardly formed on both the left and right side portions of the front end side of the memory piece 21B assembled in the memory rail 21A. Thus, the slide of the memory piece 21B described above with respect to the memory rail 21A is held in a locked state via the engaging claws 21Ba2. The position at which the slide in the front-rear direction with respect to the memory rail 21A of the memory piece 21B is locked is set to be the same as the position at which the slide in the front-rear direction of the slide rail 10 is locked.

  At the front edge of each engagement hole 21Ab on the front end side formed in the left and right shoulder portions of the memory rail 21A described above, the shape portion of each shoulder mouth constituting these edges is L-shaped toward the inside of the rail. A locking portion 21Ac that is bent into a protruding shape is formed. As shown in FIG. 34, the seat portions 21Ac are moved to the lock position (limit position P1: front most) on the front end side in the lock area A1 of the slide rail 10 along with the memory piece 21B. At this time, the engagement is made with the engaging claws 21Ba2 formed on both the left and right side portions on the front end side of the memory piece 21B to restrict the memory piece 21B from moving further forward.

<< Configuration of Memory Piece 21B >>
As shown in FIGS. 10 and 37, the memory piece 21 </ b> B has a seat surface portion 21 </ b> Ba having a substantially flat plate shape that is long in the front-rear direction, and is raised from the center of the rear portion of the seat surface portion 21 </ b> Ba to the rear side. The configuration includes an extending portion 21Bb that extends and a posture holding portion 21Bc that holds the bottomed posture formed by the shape of the bottom surface of the seat surface portion 21Ba. The above-described seat surface portion 21Ba has a stepped portion located on the front side of the raised portion 21Bb so that the lower surface portion of the leg piece 38D of the rotation member 38 of the operating mechanism 30 described later in FIG. It is formed as a concave surface portion 21Ba1 that is perforated so as to accept the downward movement.

  Further, as shown in FIGS. 10 and 37, the left and right side portions on the front end side of the seat surface portion 21Ba described above are formed with standing plate-like engagement claws 21Ba2 that are bent so as to protrude upward. ing. These engaging claws 21Ba2 are fitted into the respective engaging holes 21Ab formed in the left and right shoulder portions of the memory rail 21A described above with reference to FIG. 10 from the lower side, whereby the memory rail 21A of the memory piece 21B is inserted. It functions as a lock portion that locks the slide in the front-rear direction.

  In addition, the left and right side portions of the seat surface portion 21Ba described above are formed with bottomed portions 21Ba3 that are bent back into a U-shaped cross section on the lower side. These bottomed portions 21Ba3 are formed in a shape that extends in the longitudinal direction in a substantially constant U-shaped cross-sectional shape that is symmetrical with each other along the left and right side edges of the seat surface portion 21Ba. . As shown in FIG. 13, each of the above-mentioned bottomed portions 21Ba3 engages each engaging claw 21Ba2 in each engaging hole 21Ab of the memory rail 21A by a spring biasing force of the leaf spring 21C described later. When in the locked state pushed up into the form of being joined, as shown in FIG. 38, the memory rail 21A is held in a raised state.

  However, as shown in FIG. 15, each of the bottomed portions 21Ba3 described above engages each of the engaging claws 21Ba2 with each of the memory rails 21A against the spring biasing force of the above-described leaf spring 21C. By being pushed down so as to be removed from the hole 21Ab, as shown in FIG. 16 and FIG. 40, the bottom of the memory rail 21A is attached to the bottom so as to be in line contact with each other in the longitudinal direction. The state where the maximum depressed position of 21B is regulated is taken.

  As shown in FIGS. 10 and 37, each of the standing plate-like engaging claws 21Ba2 formed on the left and right side portions on the front end side of the seating surface portion 21Ba described above has a U-shaped cross section of each bottomed portion 21Ba3 described above. Are formed so as to protrude upward from the front end portion of the previous edge bent back.

  The raised portion 21Bb is formed in a shelf shape that protrudes upward from the above-described seat surface portion 21Ba and extends rearward. As shown in FIGS. 6 to 7 and 13, the above-described raised portion 21 </ b> Bb is provided with a leg piece 38 </ b> D of a rotation member 38 of the operation mechanism 30 described later at the front end portion and at the rear end portion. A leg link 22Ab of a trigger link 22A of the memory mechanism 20 to be described later is provided as an applied state. With the above configuration, the raised portion 21Bb is held in a state of being sandwiched from the front and rear sides by the leg piece 38D of the follower member 38 and the leg side link 22Ab of the trigger link 22A in the initial state shown in FIG. It has become so. The above-described raised portion 21Bb is formed as an inclined surface 21Bb1 whose upper surface is inclined straight in a rearward downward manner.

  As shown in FIG. 13, the posture holding portion 21Bc includes a fulcrum 21Bc1 composed of the corners on the lower rear side of the seat surface portion 21Ba described above, and a bottomed portion 21Ba3 formed on both the left and right side portions of the seat surface portion 21Ba described above. And a fulcrum 21Bc2 composed of a rear lower corner. The fulcrum 21Bc2 described above is disposed and formed at an intermediate position in the front-rear direction, which is a position closer to the rear side than the front end of the above-described riding-up part 21Bb. As shown in FIG. 32, the above-described posture holding portion 21 </ b> Bc is a case where the above-described ride-up portion 21 </ b> Bb is pushed in a diagonally downward shape from the rear side by the follower member 38 of the operation mechanism 30 described later. In addition, by attaching the above-mentioned fulcrums 21Bc1 and 21Bc2 to the bottom surface of the memory rail 21A, the posture of the memory piece 21B is raised upward so that the engaging claws 21Ba2 do not disengage from the engaging holes 21Ab of the memory rail 21A. It functions as a holding part for holding in the back tilt posture.

<< Configuration of Leaf Spring 21C >>
As shown in FIGS. 10, 37 and 38, the leaf spring 21C is formed by being bent into a shape having a substantially reverse V-shape when viewed from the side. The plate spring 21 </ b> C described above is configured as a lower support portion 21 </ b> Cc that is assembled in a state in which the top plate portion serving as the top portion is applied to the center portion in the front-rear direction of the seat surface portion 21 </ b> Ba described above from the lower side. The leaf spring 21C described above includes a front leg portion 21Ca that extends obliquely from the front end of the lower support portion 21Cc to the front lower side and contacts the bottom surface of the memory rail 21A, and a rear lower side from the rear end of the lower support portion 21Cc. A rear leg portion 21Cb extending obliquely to the bottom surface of the memory rail 21A and contacting the memory piece 21B described above with the front leg portion 21Ca and the rear leg portion 21Cb at the two front and rear positions. Thus, a spring biasing force is applied to elastically enter each engagement claw 21Ba2 into each engagement hole 21Ab of the memory rail 21A from below. Here, the front leg portion 21Ca and the rear leg portion 21Cb described above each correspond to the “leg portion” of the present invention.

  Specifically, as shown in FIGS. 37 to 38, the leaf spring 21 </ b> C described above has a spring shape formed by the above-described lower support portion 21 </ b> Cc, the front leg portion 21 </ b> Ca, and the rear leg portion 21 </ b> Cb in a symmetrical shape in the front-rear direction in a side view. It is formed into a shape. As shown in FIGS. 13 and 15, the above-described leaf spring 21 </ b> C is provided at the front end portion of the raised portion 21 </ b> Bb that receives the downward pushing force from the above-described rotating member 38 in the above-described memory piece 21 </ b> B. It is assembled to the memory piece 21B so that the region directly below is supported from the lower side by the above-described support portion 21Cc. As shown in FIGS. 37 to 39, the memory piece 21B described above has a length L1 from the front end portion of the raised portion 21Bb described above to the front end of the seat surface portion 21Ba, from the front end portion of the raised portion 21Bb. The length L2 to the rear end is longer, and the length L2 is asymmetric in the front-rear direction.

  With the above configuration, even if the leaf spring 21C is formed in a shape that is symmetrical in the front-rear direction, the memory piece 21B that has a shape having an asymmetrical length relationship in the front-rear direction is disposed in the front-rear direction. It can be elastically supported from below with good balance. The above-described leaf spring 21C has a width in the left-right direction in which the lower support portion 21Cc applied from the lower side to the seat surface portion 21Ba of the memory piece 21B is narrower than the inner diameter W3 between the left and right bottomed portions 21Ba3 of the seat surface portion 21Ba. It has W1 and is assembled so as to extend in the front-rear direction through the region between the left and right bottomed portions 21Ba3.

  Further, the above-described leaf spring 21C has a region extending in the front-rear direction through a region directly below the memory piece 21B of the front leg portion 21Ca and the rear leg portion 21Cb, and is also between the left and right bottomed portions 21Ba3 of the seat surface portion 21Ba. It has a width W1 in the left-right direction that is narrower than the inner diameter W3, and extends in the front-rear direction through a region between the left and right bottomed portions 21Ba3. With the above configuration, the leaf spring 21C does not hinder the movement of the memory piece 21B being pushed down to the position where the left and right bottomed portions 21Ba3 are bottomed, as shown in FIGS.

  However, in the grounding area that is grounded on the bottom surface of the memory rail 21A that extends beyond the memory piece 21B of the front leg 21Ca described above, the space between the left and right bottomed parts 21Ba3 of the seating surface 21Ba is provided. A wide grounding portion 21 </ b> Cd having a width W <b> 2 in the left-right direction wider than the inner diameter W <b> 3 of the memory rail 21 </ b> A and having a shape expanded between the left and right side walls of the memory rail 21 </ b> A is formed. In addition, the left and right bottomed portions 21Ba3 of the seating surface portion 21Ba are also provided in the grounding region that is grounded on the bottom surface of the memory rail 21A that extends beyond the memory piece 21B of the rear leg portion 21Cb. A wide grounding portion 21Ce having a width W2 in the left-right direction wider than the inner diameter W3 between the two and the left and right side walls of the memory rail 21A is provided.

  As shown in FIG. 38, each of the wide grounding portions 21Cd and 21Ce described above has a configuration in which a spring urging force in a direction in which the front leg portion 21Ca and the rear leg portion 21Cb are always lifted on the memory piece 21B is applied. The memory rail 21A is always elastically pressed onto the bottom surface of the memory rail 21A and held in a grounded state. Further, the above-mentioned wide grounding portions 21Cd and 21Ce are formed with standing walls 21Cd1 and 21Ce1 which are bent back so that the edge portion grounded on the bottom surface of the memory rail 21A is raised upward. ing.

  As shown in FIGS. 13 and 38, each of the wide grounding portions 21Cd and 21Ce having the above-described configuration has a memory rail when the memory piece 21B is lifted upward and engaged with the memory rail 21A. A foreign object such as gravel (not shown) that has fallen on the memory rail 21A due to a shape projecting widely in the left-right direction as pressed against the bottom surface of the left-right direction on the bottom surface of the 21A. Intrusion can be prevented. Specifically, each of the wide grounding portions 21Cd and 21Ce has the standing walls 21Cd1 and 21Ce1 rising from the grounding region so that the foreign matter such as gravel gets over the wide grounding portions 21Cd and 21Ce and enters the region immediately below the memory piece 21B. This can be prevented appropriately.

  Further, as shown in FIGS. 16 and 40, each of the wide grounding portions 21Cd and 21Ce has a bottom surface of the memory rail 21A even when the memory piece 21B is pushed down so as to be disengaged from the memory rail 21A. Maintaining a state of being pressed in a state where it is widely grounded in the left and right direction, foreign matter such as gravel that has fallen on the bottom surface of the memory rail 21A due to the shape projecting widely in the left and right direction is a region directly below the memory piece 21B. Intrusion can be prevented. Specifically, the wide grounding portions 21Cd and 21Ce are made up of foreign materials such as gravel by means of the standing walls 21Cd1 and 21Ce1 that rise from the grounding region even when the memory piece 21B is pushed down. It is possible to appropriately prevent the vehicle from getting over and entering the region immediately below the memory piece 21B.

  Therefore, the wide grounding portions 21Cd and 21Ce described above are widely grounded in the left and right directions on the bottom surface of the memory rail 21A even when the memory piece 21B is pulled back and forth as shown in FIG. 17 after the release operation. In this state, it is possible to appropriately prevent foreign matter such as gravel from entering the region immediately below the memory piece 21B.

  The standing wall 21Ce1 formed on the above-mentioned wide grounding portion 21Ce on the rear side is formed such that the rising height from the grounding surface is lower than the standing wall 21Cd1 formed on the wide-side grounding portion 21Cd on the front side. With the above configuration, even if the standing wall 21Ce1 formed on the rear wide grounding portion 21Ce is formed so as to rise from the rear side position from the rear end of the memory piece 21B, it is shown in the drawings of FIG. 25, FIG. As described above, the movement of the trigger link 22A pressed against the rear end of the memory piece 21B from the rear side is not hindered. Here, the above-described trigger link 22A corresponds to the “link member” of the present invention.

  Further, as shown in FIGS. 37 to 39, each of the wide grounding portions 21Cd and 21Ce described above has a wide shape in a region between the grounding region and the front end or the rear end of the memory piece 21B. Overhanging surface regions 21Cd2 and 21Ce2 are formed so as to extend toward the front end or rear end of the memory piece 21B. With the above configuration, the wide grounding portions 21Cd and 21Ce cover the gaps T1 and T2 between the grounding regions and the front end or the rear end of the memory piece 21B by the projecting shapes of the projecting surface regions 21Cd2 and 21Ce2 described above. Thus, it is possible to appropriately prevent foreign matter such as gravel from entering the region immediately below the memory piece 21B from the gaps T1 and T2.

  The overhanging surface regions 21Cd2 and 21Ce2 of the above-mentioned wide grounding portions 21Cd and 21Ce are front overhangs in which the gap T1 is set wide because the lengths L1 and L2 in the front-rear direction of the memory piece 21B are asymmetrical. The surface region 21Cd2 is formed so that the protrusion in the front-rear direction toward the memory piece 21B is longer than the rear protrusion surface region 21Ce2 where the gap T2 is set narrower. With the above configuration, the wide grounding portions 21Cd and 21Ce are located within the region immediately below the memory piece 21B from the gaps T1 and T2 in accordance with the wide and narrow gaps T1 and T2 in the front-rear direction formed between the memory pieces 21B. It is possible to appropriately prevent foreign matter such as gravel from entering.

<< Operation of the memory body 21 >>
As shown in FIG. 13, in the memory body 21 described above, the engaging claws 21Ba2 of the memory piece 21B described above are in memory in the initial state in which the above-described sheet position is placed at the storage position before the change of the memory piece 21B. As a state of being fitted in each engagement hole 21Ab of the rail 21A, the position of the memory piece 21B in the front-rear direction is held in a fixed state. 14 to 18, when the seat position is adjusted by operating the loop handle 5 from the initial state described above, the memory piece 21B is engaged with the memory rail 21A. The movement operation is performed in such a manner that the sheet position is removed from the combined state and rotated in the moving direction of the seat position.

  Specifically, the memory body 21 described above is operated by the memory piece 21B described later by pulling up the loop handle 5 described above from the initial state shown in FIG. 14 to the shape shown in FIGS. The rotating member 38 of the mechanism 30 is pushed downward against the spring biasing force of the leaf spring 21C. Thereby, each engagement claw 21Ba2 of the memory piece 21B is removed downward from each engagement hole 21Ab of the memory rail 21A, and the memory piece 21B can move in the front-rear direction with respect to the memory rail 21A. Is switched to.

  Accordingly, as shown in FIG. 17, the seat position is lowered to the rear side while maintaining the operation state of the loop handle 5 from the released state, so that the rotating member is moved to the raised portion 21Bb of the memory piece 21B. A pressing force from the front side is applied from 38, and the memory piece 21B is pushed to a position corresponding to the movement position of the sheet position. Further, when the seat position is moved to the front side while maintaining the operation state of the loop handle 5 described above, the above-described memory piece 21B is pressed against the above-described raised portion 21Bb from the rear side. In response to a pressing force from the rear side from the trigger link 22A, the trigger link 22A is pushed to a position corresponding to the movement position of the seat position.

  Then, as shown in FIG. 18, the memory body 21 described above is released from the above-described pushing state of the memory piece 21 </ b> B by the rotating member 38 when the operation of the loop handle 5 is returned at the above-described movement position. Thus, the memory piece 21B is brought into an engaged state in which each engaging claw 21Ba2 is fitted into each corresponding engaging hole 21Ab of the memory rail 21A at the moving position by the spring biasing force of the plate spring 21C described above. By the above engagement, the position of the memory piece 21B in the front-rear direction with respect to the memory rail 21A is returned to the fixed state.

  On the other hand, as shown in FIGS. 19 to 25, when the seat position is adjusted by operating the passenger lever 6 from the initial state as described above, the memory piece 21B is connected to the memory rail 21A. Without being released from the engaged state, the seat position is left at a fixed position so as to escape the movement of the seat position. Specifically, in the memory body 21 described above, the above-described take-up lever 6 is operated from the initial state shown in FIG. 19 to the shape shown in FIG. The memory piece 21B is lifted to a position higher than the raised portion 21Bb by being operated so as to be pulled up rather than being pushed into the top.

  Therefore, as shown in FIG. 21, the memory piece 21B follows the movement of the seat position even if the seat position is lowered to the rear side while maintaining the operation state of the passenger lever 6 as shown in FIG. Left in place. Therefore, as shown in FIG. 22, in the memory body 21 described above, the memory piece 21B remains in the position before the change of the seat position even when the operation of the passenger lever 6 is returned at the above-described movement position of the seat position. It is held as a state.

  As shown in FIG. 23, the memory body 21 described above has the memory piece 21 </ b> B in the position before the change of the seat position described above even when the passenger lever 6 is operated again at the position where the seat position is changed to the rear side. Is retained as a state left behind. Then, as shown in FIG. 24, the above-described memory body 21 moves up the memory piece 21B by returning the seat position to the front side while maintaining the operation state of the passenger lever 6 as shown in FIG. A trigger link 22A of a detection operation body 22 (to be described later) is pressed against the part 21Bb from the rear side, and the trigger link 22A is operated so as to be turned around in accordance with the movement returned to the front side of the seat position.

  As a result of the above operation, as shown in FIG. 25, the memory member 21 moves the memory member 21 </ b> B through the movement that cancels the operation state of the passenger lever 6 through the operation of the detection operation body 22 described above. Is returned to the same state as the initial state applied to the front portion of the raised portion 21Bb at a position where the raised portion 21Bb is moved forward.

  On the other hand, in the memory body 21 described above, the loop handle 5 is operated as shown in FIG. 30 from the state where the seat position is moved backward leaving the memory piece 21B described above with reference to FIG. When the seat position is returned to the front side in the operation state, as shown in FIG. 31, the above-mentioned turning member 38 which is in the operation state pushed down by the operation of the loop handle 5 becomes the memory piece. The memory piece 21B is pressed against the raised portion 21Bb of the 21B from the rear side, and the memory piece 21B is pushed and tilted against the spring biasing force of the leaf spring 21C.

  Due to the backward tilt, the memory piece 21B is in a state of accepting the forward movement of the rotation member 38 in such a manner that the rotation member 38 rides on the ride-up portion 21Bb. The memory piece 21B is pushed down by the rear end of the raised portion 21Bb due to the riding member 38 riding on the raised portion 21Bb with the advancement of the forward movement of the seat position. The rear fulcrum 21Bc1 that forms the bottom posture holding portion 21Bc is first inclined so as to bottom on the bottom surface of the memory rail 21A.

  As shown in FIG. 32, the memory piece 21B described above has a maximum center side as shown in FIG. 32 due to the progress of the advancement movement on the ride-up part 21Bb of the turning member 38 accompanying the advance movement of the seat position. The fulcrum 21Bc2 is also sunk to the position where it bottoms on the bottom surface of the memory rail 21A. However, even if the memory piece 21B described above is depressed as described above, each of the engaging claws 21Ba2 on the front end side of the memory support 21Bc is attached to the memory rail 21A by the bottom of the fulcrums 21Bc1 and 21Bc2 of the attitude holding portion 21Bc described above. The posture state in which each engagement hole 21Ab is inserted can be maintained.

  As shown in FIG. 33, the above-mentioned memory body 21 is moved forward by the turning member 38 due to the backward tilting of the memory piece 21B described above, so that the turning member 38 brings the raised portion 21Bb of the memory piece 21B to the front side. The memory piece 21B is lifted upward by the spring urging force of the leaf spring 21C by moving to the position where it has been climbed over, and the accompanying member 38 is dropped into the front portion of the ride-up part 21Bb by its relative movement. It is supposed to return to the state.

  Specifically, the memory piece 21B described above is in an operation state in which the entire memory piece 21B is pushed downward in a straight posture while returning to a backward tilted posture by the turning member 38 that is in a push-down operation state in accordance with the return movement described above. Thus, the same state as shown in FIG. 15 is returned to the state operated by the follower member 38 so as to be disengaged from the engaged state with the memory rail 21A.

<< Concerning Specific Configuration of Detection Actuator 22 >>
Next, a specific configuration of the detection operation body 22 will be described. As shown in FIGS. 6 to 9 and 13, the detection operation body 22 is provided by being assembled to a base plate 31 of an operation mechanism 30 (described later) assembled on the upper rail 12 of the slide rail 10 described above. Specifically, the detection operation body 22 described above includes a trigger link 22 </ b> A rotatably connected to the rear side region of the base plate 31 and a cancel link rotatably connected to the upper side region of the base plate 31. 22B and an operation link 22C that operates by transmitting the rotation of the trigger link 22A to the cancel link 22B.

<< Configuration of Trigger Link 22A >>
The trigger link 22A described above has a link shape that is elongated in the height direction, and an intermediate pin in the height direction has an axis pin that directs the axis in the sheet width direction with respect to the base plate 31 described above. 22Aa is provided in a state of being pin-coupled so as to be rotatable. More specifically, the trigger link 22A described above extends in a shape that curves from the connecting portion with the shaft pin 22Aa to the upper front side from the connecting portion with the shaft pin 22Aa. The head-side link 22Ac that comes out is composed of two links.

  The above-described leg side link 22Ab is normally rotated counterclockwise about the shaft pin 22Aa toward the paper surface of FIG. 13 by the biasing force of a spring (not shown) hooked between the above-described head side link 22Ac. It is in a state of being urged to rotate. With the above urging, the leg-side link 22Ab is normally in a state in which the rotational posture with respect to the head-side link 22Ac is locked at a rotation position where the leg-side link 22Ac is abutted against the locking piece 22Ac1 formed to protrude from the head-side link 22Ac. It is supposed to be held as.

  The head side link 22Ac is normally urged to rotate clockwise about the shaft pin 22Aa by the urging force of a spring (not shown) hooked between the head side link 22Ac and the base plate 31 described above. It is in a state. Due to the urging, the head side link 22Ac is normally integrated with the head side link 22Ac in the rotational direction so that the lower end portion of the leg side link 22Ab described above is the raised portion 21Bb of the memory piece 21B described above. The rotation posture with respect to the base plate 31 is held in a locked state at a rotational position where the base plate 31 is pressed and locked from the rear side.

  The trigger link 22 </ b> A having the above-described configuration has a long hole 31 </ b> C in which a shaft pin 22 </ b> Ca that rotatably connects the upper end of the head-side link 22 </ b> Ac and a rear end of an operation link 22 </ b> C described later extends in an arc shape formed in the base plate 31. By being set as the structure penetrated in, it is set as the structure which can be rotated with respect to the baseplate 31 in the range which the shaft pin 22Ca mentioned above can pass the inside of the long hole 31C. The long hole 31C described above is formed in a curved shape in an arc shape drawn around the shaft pin 22Aa serving as the rotation center of the trigger link 22A described above.

<< Configuration of Cancel Link 22B >>
The cancel link 22B is provided in a state where the upper end of the cancel link 22B is rotatably connected by a shaft pin 22Ba whose axis is directed in the sheet width direction in the upper region of the base plate 31 that is in front of the trigger link 22A. . The cancel link 22B described above is pin-connected so that the kick cam 22Bb can be further rotated by a shaft pin 22Bb1 whose shaft is oriented in the seat width direction at a location extending from the connection location with the shaft pin 22Ba to the front lower side. It is set as the structure.

  The kick cam 22Bb described above is normally rotated counterclockwise around the shaft pin 22Bb1 toward the paper surface of FIG. 13 by the biasing force of a spring (not shown) hooked between the cancel link 22B described above. It is supposed to be in a state of power. By the above urging, the kick cam 22Bb is normally rotated such that the locking piece 22Bb2 formed to protrude from the outer periphery of the kick cam 22Bb to the locking link 22B protrudes from the cancel link 22B. At the position, the rotation posture with respect to the cancel link 22B is held in a locked state.

  The kick cam 22Bb described above has a kick protrusion piece 22Bb3 that protrudes so as to extend the shape further from the cancel link 22B to the front lower side in a state where the rotational posture with respect to the cancel link 22B is locked. It is said that. As shown in FIG. 21, when the cancel link 22B described above is rotated counterclockwise around the shaft pin 22Ba, the kick cam 22Bb is engaged with the operation mechanism 30 described later on the movement trajectory. When the kicked pin 33C of the detachment cam 33 is positioned, the cancel link 22B rotates in the clockwise direction in the figure with respect to the cancel link 22B around the shaft pin 22Bb1 so as to avoid interference with the kicked pin 33C. It is designed to function so that it can escape the rotational movement.

  However, as shown in FIG. 24, when the kick cam 22Bb is rotated so that the cancel link 22B is rotated back from the position where the cancel link 22B is rotated about the shaft pin 22Ba in the clockwise direction shown in the figure. The kicked pin 33C of the engagement / disengagement cam 33 of the operation mechanism 30 (to be described later) located on the movement locus is pushed and kicked by integral rotation with the cancel link 22B, and the engagement / disengagement cam 33 is engaged with the operation cam 34. It functions to remove from the combined state.

  The cancel link 22B having the above-described configuration has a shaft pin 22Cb that rotatably connects an intermediate portion in the link length direction and a front end of an operation link 22C, which will be described later, in a long hole 31D that extends in an arc shape formed in the base plate 31. The shaft pin 22Cb described above can be rotated with respect to the base plate 31 within a range in which the shaft pin 22Cb can pass through the long hole 31D. The long hole 31D described above is formed in a curved shape in the shape of an arc drawn at the center of the shaft pin 22Ba serving as the rotation center of the cancel link 22B described above.

<< Configuration of Operation Link 22C >>
As shown in FIG. 13, the operation link 22C has a link shape that is long in the front-rear direction. The operation link 22C is in a state in which the rear end thereof is rotatably connected to a shaft pin 22Ca whose axis is oriented in the seat width direction with respect to the upper end of the head side link 22Ac of the trigger link 22A. Further, the operation link 22C is in a state where the front end of the operation link 22C is rotatably connected by a shaft pin 22Cb whose axis is directed in the sheet width direction with respect to the intermediate portion in the link length direction of the cancel link 22B.

  With the above configuration, the operation link 22C connects the trigger link 22A and the cancel link 22B described above in a state where power can be transmitted, and when the rotation posture of the trigger link 22A is locked in the initial state, The rotation posture is also locked in the initial state. Then, as shown in FIG. 21, the operation link 22C rotates away from the contact state with the memory piece 21B by the backward movement of the seat position, and rotates in the clockwise direction shown in the figure around the shaft pin 22Aa. By moving, the amount of rotational movement is transmitted to the cancel link 22B, and the cancel link 22B is rotated in the counterclockwise direction around the shaft pin 22Ba.

  Further, as shown in FIG. 24, the operation link 22C is pressed against the memory piece 21B again from the rear side by the forward movement of the seat position from the retracted position of the seat position, so that the shaft pin 22Aa is centered. By rotating in the counterclockwise direction in the figure, the amount of rotational movement is transmitted to the cancel link 22B, and the cancel link 22B is rotated in the clockwise direction in the figure about the shaft pin 22Ba.

<< About the operation of the detection operation body 22 >>
As shown in FIG. 13, in the initial state in which the above-described seat position is placed at the pre-change storage position of the memory piece 21B, the detection operation body 22 described above is configured so that the leg-side link 22Ab of the trigger link 22A described above is in the above-described state. The state in which the head-side link 22Ac centered on the shaft pin 22Aa and the leg-side link 22Ab is pressed against the rear surface portion of the raised portion 21Bb of the memory piece 21B by a spring biasing force (not shown). The integral clockwise movement in the illustrated direction is held in a stopped state at an intermediate position.

  As shown in FIGS. 14 to 18, the detection operation body 22 described above is not operated at all even if the loop handle 5 is operated, and the state changes before and after the operation of the loop handle 5. There is no such thing. However, as shown in FIGS. 19 to 25, the detection operation body 22 described above moves the seat position leaving the memory piece 21 </ b> B when the seat position is adjusted by operating the passenger lever 6 from the initial state described above. Along with this, it is moved so as to detect the state separated from the memory piece 21B or the state pressed against the memory piece 21B.

  Specifically, the above-described detection operation body 22 is not particularly operated even when the above-described entry / exit lever 6 is operated in the form shown in FIG. 20 from the initial state shown in FIG. However, as shown in FIG. 21, the detection operation body 22 described above moves the seat position to the rear side while leaving the memory piece 21 </ b> B by the operation of the above-described entry / exit lever 6, thereby causing the leg side of the trigger link 22 </ b> A described above. The link 22Ab is removed from a contact state with the rear surface portion of the raised portion 21Bb of the memory piece 21B, and the head side link 22Ac and the leg side link 22Ab are integrated by a spring biasing force (not shown). The leg-side link 22Ab is rotated in the clockwise direction as shown in the figure by kicking it forward from the shaft pin 22Aa.

  The above-described rotational movement of the trigger link 22A by the spring biasing force in the clockwise direction around the shaft pin 22Aa is the long hole 31C through which the shaft pin 22Ca connected to the upper end of the head-side link 22Ac is passed. It is locked by hitting the rear end. Then, due to the rotational movement of the trigger link 22A, the cancel link 22B is rotationally operated in a counterclockwise direction around the shaft pin 22Ba via the operation link 22C connected to the trigger link 22A.

  At that time, the cancel link 22B is in a state where the cancel link 22B protrudes to a position on the movement locus in accordance with the operation of the above-described entry / exit lever 6 with respect to the kicked pin 33C of the engagement / disengagement cam 33 of the operation mechanism 30 described later. The kick cam 22Bb of the kick cam 22Bb is rotated so as to be pressed from above. However, when the kick link 22Bb3 of the kick cam 22Bb is pressed against the kick pin 33C of the engagement / disengagement cam 33 from the rotation direction, the cancel link 22B described above has the kick cam 22Bb against the cancel link 22B and the shaft pin 22Bb1. It rotates in the clockwise direction in the figure against a spring urging force (not shown) around the center, and can be rotated to a position where it can pass through the kicked pin 33C while escaping the hit with the kicked pin 33C. .

  Then, when the cancel link 22B described above is rotated to a position where it passes through the kicked pin 33C described above, the above-described kick cam 22Bb is applied to the locking protrusion 22Bc of the cancel link 22B by a spring biasing force (not shown). It will be returned to the posture state. As shown in FIG. 22, the detection operation body 22 described above is not particularly operated even if the operation of the passenger lever 6 is returned after the seat position described above is moved backward. Further, as shown in FIG. 23, the detection operation body 22 described above is not particularly operated even when the passenger lever 6 is operated again at the position where the seat position is changed to the rear side.

  However, as shown in FIG. 24, the detection operation body 22 described above is configured so that the leg-side link 22Ab of the trigger link 22A described above is returned when the seat position is returned to the front side while the operation state of the entry / exit lever 6 is maintained. The memory piece 21B is operated to be pushed counterclockwise around the shaft pin 22Aa as it is pressed against the raised portion 21Bb from the rear side and returned to the front side of the seat position. .

  As a result of the above operation, the detection operation body 22 transmits the rotation of the trigger link 22A described above to the cancel link 22B through the operation link 22C, and the cancel link 22B is pushed in the clockwise direction in the figure about the shaft pin 22Ba. Rotate. By this rotation, the kick link piece 22Bb3 of the kick cam 22Bb is pressed from below on the cancel link 22B against the kicked pin 33C of the above-described engagement / disengagement cam 33 protruding to the position on the movement locus.

  At that time, even if the above-described kick cam 22Bb is pressed against the kicked pin 33C from below, the cancel link 22B is rotated counterclockwise in the figure about the shaft pin 22Bb1 with respect to the cancel link 22B. The state is integrated with the cancel link 22B without rotating in the direction. Accordingly, as the cancel link 22B moves, the kick protrusion 22Bb3 of the kick cam 22Bb pushes and kicks the kick pin 33C so that the engagement / disengagement cam 33 is disengaged from the operation cam 34 described later. It is designed to operate.

  By the above operation, the detection operation body 22 cancels the release state of the slide lock of the slide rail 10 by the operation mechanism 30 described later, which has been maintained by the operation state of the above-described entry / exit lever 6, and as shown in FIG. The lock spring 13 is locked and the slide rail 10 is returned to the slide-locked state. By the above operation, the detection operation body 22 is returned to the same state as the initial state in which the leg side link 22Ab of the trigger link 22A described above is pressed against the raised portion 21Bb of the memory piece 21B from the rear side.

  The detection operation body 22 described above operates to return the lock spring 13 to the locked state by pressing the trigger link 22A against the raised portion 21Bb of the memory piece 21B from the rear side as described above. As described above, the locking surface portion where the head side link 22Ac of the trigger link 22A described above with reference to FIG. 24 projects into the hook shape of the stopper bracket 15 described above with reference to FIG. It is applied to 15A from the front side and operates to return the lock spring 13 to the lock state in the same manner.

  The detection operation body 22 configured as described above further moves from the state where the seat position is placed at the storage position before the change of the memory piece 21B shown in FIG. However, when it is moved to the front side as shown in FIG. 26, it is possible to release the movement without overloading the trigger link 22A pressed against the memory piece 21B from the rear side. An avoidance mechanism 22M is provided.

  Specifically, the overload avoidance mechanism 22M described above is configured so that the trigger link 22A described above is in a memory state as shown in FIG. 26 from the initial position where the memory piece 21B is pressed from the rear side (see FIG. 20). The cancel link 22B that rotates by receiving the trigger link 22A and its rotation when receiving the input of the force pushed in the counterclockwise direction around the shaft pin 22Aa by being pressed against the piece 21B from the rear side. Are configured by a mechanism that allows them to escape in the rotational direction that receives the input against a spring biasing force (not shown).

  Each escape rotation of the trigger link 22A and the cancel link 22B described above reaches the front end of the long hole 31C through which the shaft pin 22Ca connected to the upper end of the head side link 22Ac of the trigger link 22A is passed. A long hole 31D through which the shaft pin 22Cb connected to the intermediate portion in the link length direction of the cancel link 22B described above is allowed to escape from the initial position of the trigger link 22A. The rotation from the initial position of the cancel link 22B can be released until the upper end of the cancel link 22B is reached.

  By the above-described overload avoidance mechanism 22M, the detection operation body 22 is stored in a manner such that the trigger link 22A rides on the memory piece 21B while being in a forward leaning posture with the advance movement from the initial position of the seat position. It slides to the position over the piece 21B on the front side. As shown in FIG. 27, when the trigger link 22A has moved over the memory piece 21B to the front side, the rotation posture of the trigger link 22A is changed with respect to the memory piece 21B by a spring biasing force (not shown). The leg side link 22Ab is returned to the form of kicking out to the front side in the same state as shown in FIG.

  In addition, the detection operation body 22 described above further starts from the position where the trigger link 22A shown in FIG. 27 crosses the memory piece 21B to the front side, and as shown in FIG. 28, the seat position moves the trigger link 22A from the memory piece 21B. Even when the rear side is moved so as to return to the rear side, a release mechanism 22N is provided that can release the movement without overloading the trigger link 22A pressed against the memory piece 21B from the front side. ing.

  Specifically, the above-described escape mechanism 22N receives an input of a force that is rotated clockwise around the shaft pin 22Aa by the above-described trigger link 22A being pressed against the memory piece 21B from the front side. At this time, the leg-side link 22Ab of the trigger link 22A is configured by a mechanism that allows the head-side link 22Ac to leave the head-side link 22Ac so that the leg-side link 22Ab can escape in the rotational direction that has received the input alone against an unillustrated spring biasing force. Yes.

  That is, the above-described trigger link 22A has the locking piece 22Ac1 of the head-side link 22Ac when the above-described leg-side link 22Ab rotates in the illustrated counterclockwise direction around the shaft pin 22Aa with respect to the head-side link 22Ac. The head-side link 22Ac rotates together with the head-side link 22Ac, but the leg-side link 22Ab is hooked between the head-side link 22Ac against rotation in the reverse direction (not shown). The head side link 22Ac can be left against the spring urging force and can be rotated.

  Therefore, by the escape mechanism 22N having the above-described configuration, the detection operation body 22 causes the leg-side link 22Ab of the trigger link 22A to move above the memory piece 21B with respect to the head-side link 22Ac as the seat position moves backward. It is ridden in a shape that bends in a middle-folded manner and rides on the memory piece 21B to the rear side. As shown in FIG. 29, when the leg-side link 22Ab of the trigger link 22A rides on the raised portion 21Bb of the memory piece 21B, the detection operation body 22 is in the memory described above. The piece 21B is pushed backward and inclined in the same manner as described above with reference to FIG. 31 against the spring biasing force of the leaf spring 21C by the action of the force pushed from above.

  Then, as shown in FIG. 29, the above-described leg-side link 22Ab of the trigger link 22A corresponds to FIG. 20 before the seat position is moved to the front side by the movement of the memory piece 21B being pushed backward. The amount of movement to return to the position is a position that crosses the raised portion 21Bb rearward by the counterclockwise rotation around the shaft pin 22Aa while sliding on the inclined surface 21Bb1 of the raised portion 21Bb of the memory piece 21B. And is returned to the same state as the initial state pressed against the raised portion 21Bb of the memory piece 21B from the rear side.

<< Concerning Specific Configuration of Operation Mechanism 30 >>
Next, a specific configuration of the operation mechanism 30 will be described. As shown in FIGS. 5 to 9 and 13, the operation mechanism 30 is attached to a base plate 31 that serves as a base assembled on the upper rail 12 of the slide rail 10 disposed on the inner side (left side) in the vehicle width direction described above. It is assembled and provided.

  14 to 18, the operation mechanism 30 described above releases the lock spring 13 of the slide rail 10 from the locked state by operating the loop handle 5 described above, and also releases the memory piece 21B from the engaged state with respect to the memory rail 21A. The release operation mechanism 30A for switching to a state where it can be rotated in the sliding direction, and the memory piece 21B described above left in the state of being engaged with the memory rail 21A by the operation of the above-described entry / exit lever 6 as shown in FIGS. And a memory operating mechanism 30B for operating the lock spring 13 of the slide rail 10 so as to be released from the locked state.

  Specifically, as shown in FIGS. 6 to 7, 11, and 13, the operation mechanism 30 is rotatably connected to the base plate 31 serving as the base and the front lower side region of the base plate 31. The release arm 32, the engagement / disengagement cam 33 rotatably connected to the intermediate portion in the length direction of the release arm 32, and the pin connection to the front lower side region of the base plate 31 so as to be rotatable coaxially with the release arm 32. The operation cam 34, the rod 35 connected to the operation cam 34 so as to rotate integrally therewith, and the pull-up connected to the front side region of the base plate 31 so as to be rotatable. The operation link 36, a pressure receiving member 37 that is pin-connected to be hung from the rear end of the lifting operation link 36, and a state in which the pressure receiving member 37 is elastically connected to the pressure receiving member 37 via a spring (not shown). There is a co-rotation member 38 disposed in a state where the guide so as to only be movable in the height direction, a configuration with respect to the base plate 31 and.

<< Configuration of Base Plate 31 >>
As shown in FIGS. 8 to 9, the above-described base plate 31 is configured by combining a plurality of plate materials such as steel, and has a bottom plate portion and a vertical plate portion combined in a double vertical plate shape inside and outside. It is formed into a shape. The base plate 31 described above has a bottom plate portion bolted onto the top plate portion 12A of the upper rail 12 described above and integrally fixed thereto. The base plate 31 described above is assembled in such a manner that the constituent members of the detection operation body 22 and the operation mechanism 30 of the memory mechanism 20 described above are sandwiched between the standing plate shapes combined in the inner and outer layers. Has been.

  Further, as shown in FIG. 7, the right side surface of the rising surface portion 31 </ b> F constituting the right side standing plate shape of the base plate 31 passes through the inner region in the seat width direction which is the right region of the left slide rail 10. A bracket 39 for fixing an intermediate portion of the wire harness W / H routed by the resin clip CL is integrally welded and attached. The bracket 39 described above is formed of a single sheet of steel or the like that is long in the front-rear direction with the surface facing in the sheet width direction. The bracket 39 described above does not include the square holes 39A and 31Fa that are formed in the form of being cut out at the front edge of each of the rising surfaces 31F of the base plate 31 and that penetrate in the sheet width direction. By using the positioning square pins for positioning so as to overlap each other in the sheet width direction, the mounting position with respect to the base plate 31 is positioned.

  Specifically, the bracket 39 described above is a crank that is bent in a crank shape toward the right side (inner side in the seat width direction) at a midpoint extending from the front edge where the square hole 39A is formed to the rear side. The shape has a portion 39B. The bracket 39 extends in a front-rear direction in which a middle portion of the wire harness W / H is fixed from the right side by insertion of the clip CL on a surface portion that extends straight from the crank portion 39B to the rear side. An oval mounting hole 39C is formed. A diaphragm-shaped bead 39B1 that swells to the right is formed in a continuous manner across the surface portion extending from the crank portion 39B to the front side at the center portion in the height direction of the crank portion 39B.

  The bracket 39 described above is applied to a state in which the surface portion extending straight from the crank portion 39B to the front side is in surface contact with the right side surface of the rising surface portion 31F of the base plate 31 described above, and is in contact with each other. A plurality of portions are welded and firmly joined together. The wire harness W / H attached to the attachment hole 39 </ b> C of the bracket 39 described above is bent to the outer region in the seat width direction which is the left region of the left slide rail 10 in the rear region of the base plate 31. It is routed in the form. Although the wiring harness W / H is wired so as to cross the base plate 31 in the seat width direction by the above wiring, the wire harness W / H has a surplus length that does not cause a tension even when the slide rail 10 is slid in the front-rear direction. It is said that.

  However, even if the wire harness W / H is routed across the base plate 31 in the seat width direction in the rear region of the base plate 31 as described above, the bracket 39 that fixes the wire harness W / H is secured. With this shape, the wire harness W / H can be held in a detoured state so as not to interfere with each member protruding from the upper rail such as the base plate 31 even when the slide rail 10 is moved in the front-rear direction. It has become. Specifically, the mounting hole 39C of the bracket 39 that fixes the above-described wire harness W / H extends to the vicinity of the rear edge of the rising surface portion 31F of the base plate 31, and is separated from the rising surface portion 31F by the crank portion 39B. This is due to the fact that it is formed on the surface portion separated to the right side (inner side in the sheet width direction).

<< Configuration of Release Arm 32 >>
As shown in FIGS. 8 to 9, 11, and 13, the release arm 32 has an arm shape that is elongated in the height direction, and its lower end is on the left side of the rod 35 to be described later. The end portion is rotatably connected to the base plate 31 and is axially passed through an operation shaft 35A that is oriented in the sheet width direction so as to be rotatably connected to the operation shaft 35A. . The release arm 32 is normally urged to rotate counterclockwise in FIG. 13 about the operation shaft 35A by the urging force of a spring (not shown) hooked between the release arm 32 and the base plate 31 described above. It is in a state. Due to the above urging, the release arm 32 is always against the base plate 31 at a rotational position where it is abutted against a locking piece 31A formed in a shape protruding in the sheet width direction at the front edge of the base plate 31. The rotation posture is held in a locked state.

  At the upper end of the release arm 32 described above, the tip of a cable 32 </ b> A that transmits the operating force from the passenger lever 6 is connected. The cable 32A described above has a double cable structure in which a linear inner cable is passed through a tubular outer cable, and the front end of the outer cable is integrally hooked and fixed to the rear side region of the base plate 31. Then, the tip of the inner cable fed out therefrom is connected to the upper end of the release arm 32.

  As shown in FIGS. 14 to 18, the release arm 32 configured as described above is not operated even when the loop handle 5 described above is operated, and the state changes before and after the operation of the loop handle 5. There is no such thing. However, as shown in FIG. 19, the release arm 32 described above is operated via the cable 32A as shown in FIG. 20 by the operation of the passenger lever 6 connected to the upper end of the release arm 32 via the cable 32A. In response to the transmission of the operating force, it is rotated in the clockwise direction in the figure around the operating shaft 35A.

  The release arm 32 described above always receives transmission of the operation force via the cable 32A described above while the entry / exit lever 6 is operated, and as shown in FIG. It keeps being kept in the state. Then, as shown in FIG. 22, the release arm 32 is released from the above-described pulling operation state by the cable 32A when the operation of the above-described getting-on / off lever 6 is returned, and the above-described release arm 32 is released by the spring biasing force (not shown). It returns to the initial state where it abuts against the locking piece 31A.

As shown in FIG. 13, the engagement / disengagement cam 33 is rotatably connected to the intermediate portion in the length direction of the release arm 32 described above by a shaft pin 33 </ b> A whose axis is directed in the sheet width direction. . The aforementioned engagement / disengagement cam 33 is normally rotated clockwise with respect to the release arm 32 about the shaft pin 33A by a spring biasing force (not shown) hooked between the release arm 32 and the release arm 32 described above. It is supposed to be in a state of power. Due to the urging, the engagement / disengagement cam 33 is normally bent into a circular arc shape of the operation cam 34 described later, with the push-projection piece 33B formed to protrude rearward and downward from the shaft pin 33A. It is held as a pressed state on the outer peripheral surface.

  As shown in FIG. 20, the engaging / disengaging cam 33 having the above-described configuration is formed by pushing the protruding arm 33B when the release arm 32 described above is rotated about the operation shaft 35A in the clockwise direction by the operation of the passenger lever 6. Is operated so as to rotate integrally with the release arm 32 via the shaft pin 33A while being pressed onto the outer peripheral surface of the operation cam 34. And by the said rotation, the engagement / disengagement cam 33 presses the pressing protrusion 33B against the pressed portion 34A formed to protrude on the outer peripheral surface of the operation cam 34, and the operation cam 34 is centered on the operation shaft 35A. It is designed to push in the clockwise direction shown in the figure.

  In addition, with the above-described rotation of the engaging / disengaging cam 33, the shaft pin 33A, which is the center of rotation, is pressed against the lower surface of a pulling operation link 36, which will be described later. An operation is performed so as to pull up in the counterclockwise direction shown in the drawing centering on a certain front shaft pin 36A. The above-described engagement / disengagement cam 33 is always held in the above-described rotationally operated position while the above-described entry / exit lever 6 is operated, and is a state where the above-described operation cam 34 and the above-described lifting operation link 36 are pushed and rotated It is supposed to hold on.

The pushing protrusion 33B of the engaged and disengaged cam 33 is pressed against the pressed portion 34A, and is integrally rotated with the operation shaft 35A and is rotated around the operation shaft 35A in the clockwise direction in the drawing. Due to the rotation, the operation cam 34 is operated so as to push the operation protrusion 34B against the upper surface of the loop handle 5 from above and to push down the loop handle 5.

  As a result, the operation cam 34 is operated in the same manner as when the loop handle 5 is operated as shown in FIG. 15, and the lock spring 13 is pushed down via the loop handle 5 to be released from the locked state. ing. As shown in FIG. 21, the operation cam 34 receives the operation force from the release arm 32 via the engagement / disengagement cam 33 and pushes down the loop handle 5 while the passenger lever 6 is operated. The operation state is maintained.

  However, the operation cam 34 is returned to the initial position when the operation of the passenger lever 6 is returned as shown in FIG. Further, as shown in FIG. 24, the above-described operation cam 34 returns the seat position from the position where the seat position is retracted by the operation of the passenger lever 6 to the position where the memory piece 21B is placed. When the engagement / disengagement cam 33 described above is pushed and kicked so as to be disengaged from the engagement state with the operation cam 34, it is returned to the initial position by a spring biasing force (not shown). .

<About the configuration of the rod 35>
As shown in FIG. 4, the rod 35 is integrally connected to an operation shaft 35 </ b> A whose left end is axially oriented in the sheet width direction and is rotatably connected to the front lower side region of the base plate 31 described above. In addition, the right end portion is integrally connected to an operation shaft 35B that is axially oriented in the seat width direction and is rotatably connected to a support bracket 16 mounted on the upper rail 12 on the same side.

It is configured to be able to transmit the movement of the rotation operation to the right operation shaft 35B.

  The above-described right operation shaft 35B shown in FIG. 4 is pressed against the upper surface of the loop handle 5 on the same side by performing an integral rotation operation with the left operation shaft 35A. An arm member (not shown) to be pushed down is integrally connected. With the above-described configuration, the left and right operation shafts 35A are rotated and the right operation shaft 35B shown in FIG. Thus, the loop handle 5 attached to the slide rail 10 on each side is operated so as to be pushed down all at once. Accordingly, the lock springs 13 of the slide rails 10 on each side are operated to be pushed down all at once, so that the slide lock state of the slide rails 10 on each side is released all at once. Further, the right operation shaft 35B is also returned all at once as the rotation operation of the left operation shaft 35A is returned.

<< Configuration of Lifting Operation Link 36 >>
As shown in FIGS. 8 to 9, 11, and 13, the lifting operation link 36 has an arm shape having a long shape in the front-rear direction, and its front end portion is oriented in the seat width direction. The shaft pin 36 </ b> A is provided in a state where the pin is rotatably connected to the front side region of the base plate 31. The lifting operation link 36 protrudes in the sheet width direction connected to the upper end portion of a follow-up member 38 described later in a long hole 36 </ b> B extending in the front-rear direction formed so as to penetrate the rear end portion in the sheet width direction. The shaft pin 38B is in a state of being passed, and the initial state shown in FIG. 13 is always obtained by the action of the force that the accompanying member 38 is elastically supported by the base plate 31 via the pressure receiving member 37 described later. The position is maintained.

  As shown in FIG. 15, the above-described pulling operation link 36 allows the accompanying rotation member 38 to move when the above-described loop handle 5 is operated to operate the following rotation member 38 to be pushed down. As described above, the shaft pin 38B is slightly pushed downward while sliding the shaft pin 38B backward in the long hole 36B. However, as shown in FIG. 20, the lifting operation link 36 is operated when the release lever 32 is operated and the release arm 32 is rotated about the operation shaft 35A in the clockwise direction as shown in the figure. The lower surface is pressed from below by the shaft pin 33A, which is the center of rotation of the engagement / disengagement cam 33 connected to the shaft 32, and is rotated in the counterclockwise direction shown in the figure around the shaft pin 36A.

  By the above rotation, the lifting operation link 36 is operated so as to lift the shaft pin 38B passed through the long hole 36B on the rear end side, and the rotation member 38 is moved upward against a spring biasing force (not shown). The leg piece 38D on the lower end side of the follower member 38 is pulled up to a position higher than the raised portion 21Bb of the memory piece 21B. On the lower surface of the above-described pulling operation link 36, a relief surface 36C curved in an arc shape is formed in the middle region. The relief surface 36C is the center of rotation of the engagement / disengagement cam 33 when the above-described lifting operation link 36 is in an operation state in which the rotation member 38 is lifted to a position higher than the raised portion 21Bb of the memory piece 21B. It is formed in a region to which the shaft pin 33A is applied.

As shown in FIGS. 8 to 9, 11, and 13, the follower member 38 is formed in a plate shape having an elongated shape in the height direction, and the pressure receiving member 37 and the sheet width direction ( In the same manner as the pressure receiving member 37, the base plate 31 is provided in a state of being guided so as to be able to slide straight in the height direction. Specifically, the rotation member 38 described above is a shaft extending in the sheet width direction fixed to the above-described base plate 31 in a long hole 38A that extends straight in the height direction formed in an intermediate portion in the height direction. The support pin 31E is in a state of being passed along with the elongated hole 37A of the pressure receiving member 37.

  Further, the guide member 31 </ b> B that is bent in a shape protruding from the above-described base plate 31 in the sheet width direction is applied to the side member on the rear side thereof together with the pressure receiving member 37. With the above configuration, the follower member 38 can receive the guide by the above-described pivot support pin 31E and the guide piece 31B, and can slide straight along the pressure plate 37 together with the pressure receiving member 37 in the height direction. It is in a state supported by the shape.

  The follow-up member 38 described above is normally moved and urged in a direction in which it is pushed down by the urging force of a tension spring (not shown) hooked between the pressure-receiving member 37 and the pressure-receiving member 37 described above. It is said that. As shown in FIG. 13, the urging member 38 is normally bent in the sheet width direction from the upper end rear portion of the pressure receiving member 37 by the above biasing, as shown in FIG. 13. In this way, it is held in the initial position where it comes into contact with the locking piece 37B that protrudes from above and is locked.

  In the state of the initial position, the swivel member 38 is in a state where the leg piece 38D on the lower end side is lowered to a position lower than the upper surface of the raised portion 21Bb of the memory piece 21B described above, and the seat position is the memory piece 21B. In the initial state of being placed at the storage position before the change, the leg piece 38D on the lower end side is held in a state where the leg piece 38D is dropped onto the front portion of the raised portion 21Bb of the memory piece 21B.

  When the loop handle 5 described above is operated as shown in FIG. 15 from the initial state shown in FIG. 14, the follower member 38 is operated so as to be pushed downward via the pressure receiving member 37 described above. The As a result, the turning member 38 applies a pushing force from above to the front end portion of the raised portion 21Bb of the memory piece 21B by the pressing protrusion 38Db partially protruding from the rear side surface of the leg piece 38D on the lower end side. The memory piece 21B is pushed down. Even if the loop handle 5 is further operated to the limit position from the pushed-down operation state, the follow-up member 38 described above has the pressure-receiving member 37 pushed down by the loop handle 5 as shown in FIG. 38, the above-described tension spring (not shown) is stretched and moved so as to release an excessive amount of operation movement, so that an excessive load is not received.

  As shown in FIG. 17, the above-mentioned rotating member 38 is held in the operation state in which the memory piece 21B is pushed down by the pressing force received from the above-described pressure receiving member 37 while the above-described loop handle 5 is being operated. It has become so. Then, as shown in FIG. 18, the above-described rotation member 38 is returned to the initial position when the operation of the loop handle 5 is returned.

  Further, as shown in FIG. 19, the above-mentioned turning member 38 is connected at its upper end portion to the rear end portion of the aforementioned lifting operation link 36, and the lifting operation link 36 is shown in FIG. By being pulled up by the operation of No. 6, the bottom surface of the leg piece 38D on the lower end side is pulled up to a position where the bottom surface of the memory piece 21B exceeds the upper surface of the raised portion 21Bb. Specifically, in the above-described turning member 38, the shaft pin 38B connected to the upper end portion thereof and extending in the sheet width direction is formed in the elongated hole 36B extending in the front-rear direction formed in the rear end portion of the lifting operation link 36. It is said that it has been passed through.

  With the above-described configuration, the follow-up member 38 is operated in such a manner that the pull-up operation link 36 is pushed up by the shaft pin 33A of the engagement / disengagement cam 33 by the operation of the getting-on / off lever 6 and thereby the loop handle 5 is pushed down. While the pressure receiving member 37 is pushed down, the pressure receiving member 37 is operated so as to be pulled up by the pulling operation link 36 against the urging force of a tension spring (not shown) hooked between the pressure receiving member 37.

The slide rail device M configured as described above can adjust the seat position as follows by the operation of the getting-on / off lever 6 described above in FIG. 1 and the operation of the loop handle 5 described above in FIG. It will be moved to the state. In the following description, the state where the sheet position is placed at a storage position before the change of the memory piece 21B as shown in FIG. 13 will be described as an initial state.

<< ● Movement of each part when operating the loop handle 5 >>
First, the movement of each part when the loop handle 5 is operated from the initial state will be described with reference to FIGS. That is, when the pulling operation of the loop handle 5 is performed from the initial state shown in FIG. 14, the lock spring 13 is pushed down by the rear end portion of the loop handle 5 to be released from the locked state as shown in FIG. The member 37 is also pushed down and the memory piece 21B is pushed down via the follower member 38 to be released from the engaged state with the memory rail 21A. Although the loop handle 5 can be operated up to the limit position shown in FIG. 16, even if operated up to this position, the pressure receiving member 37 and the rotating member 38 are overloaded due to excessive operation as described above. Is not hung.

  Next, while the loop handle 5 is operated, the seat position is moved backward as shown in FIG. 17, so that the leg piece 38D of the follower member 38 is in the operation state in which the memory piece 21B is pushed down. The raising portion 21Bb is pressed to the rear side, and the memory piece 21B is moved to the moving position of the sheet position by being rotated by the rotation member 38. When the seat position is moved forward, the leg-side link 22Ab of the trigger link 22A presses the raised portion 21Bb of the memory piece 21B forward, so that the memory piece 21B is moved to the seat position moving position. It has come to go.

  When the seat position is moved to an arbitrary position and the operation of the loop handle 5 is returned as shown in FIG. 18, the lock spring 13 returns to the locked state and the pressure receiving member 37 and the rotation member 38 are also in the initial positions. The memory piece 21B is returned to the same state as the initial state at the position where the memory piece 21B is engaged with the memory rail 21A, that is, at the position where the seat position is changed.

<< ● Movement of each part when operating the entry / exit lever 6 >>
Next, with reference to FIG. 19 to FIG. 25, the movement of each part when the entry / exit lever 6 is operated from the initial state will be described. That is, when the operation of the entry / exit lever 6 is performed from the initial state shown in FIG. 19, the rear end portion of the loop handle 5 is pushed down via the operation cam 34 by the operation of the release arm 32 as shown in FIG. The lock spring 13 is pushed down by the rear end of the loop handle 5 to be released from the locked state, and the pressure receiving member 37 is also pushed down. However, on the other hand, the lifting operation link 36 is pulled up by the shaft pin 33A, which is the rotation center of the engagement / disengagement cam 33 connected to the release arm 32, and the follower member 38 is moved up and down on the memory piece 21B. It is operated to be pulled up to a position higher than 21Bb. Accordingly, even when the passenger lever 6 is operated, the memory piece 21B is held in a state of being engaged with the memory rail 21A.

  Next, by moving the seat position backward as shown in FIG. 21 with the passenger lever 6 being operated, the revolving member 38 remains in the initial position while the memory piece 21B is left in the initial position. Get over the raised portion 21Bb to the rear side. As a result of the above movement, the trigger link 22A is released from the state of being pressed against the raised portion 21Bb of the memory piece 21B from the rear side, and the leg side link 22Ab is kicked forward by a spring biasing force (not shown). Can be switched to the posture.

  When the seat position is moved to an arbitrary position and the operation of the passenger lever 6 is returned as shown in FIG. 22, the lock spring 13 is returned to the locked state, and the pressure receiving member 37 and the rotation member 38 are also in the initial positions. Returned to the state. Next, when the operation of the getting-on / off lever 6 is performed again from the moving position as shown in FIG. 23, the rear end portion of the loop handle 5 is pushed down by the operation of the release arm 32 as in the previous operation, The lock spring 13 is released from the locked state, and the turning member 38 is pulled up to a position higher than the raised portion 21Bb of the memory piece 21B.

  Next, in the above operation state, as shown in FIG. 24, by returning the seat position from the retracted position to the position where the memory piece 21B is placed, the above-mentioned rotating member 38 of the memory piece 21B is The trigger link 22A is pushed from the rear side to the raised portion 21Bb of the memory piece 21B, and the cancel link 22B is engaged and disengaged by the leading kick cam 22Bb. Is kicked so as to be disengaged from the engaged state with the operation cam 34.

  As a result of the kicking operation, as shown in FIG. 25, the operation cam 34 is returned to the initial position by a spring biasing force (not shown) even when the passenger lever 6 is maintained in the operating state. The operating state of the loop handle 5 that has been pushed and moved by the cam 34 is returned, and the lock spring 13 returns to the locked state. With the above operation, the seat position can be changed even if the getting-on / off lever 6 remains in the operating state by a simple operation of moving the seat position toward the storage position before the change with the getting-on / off lever 6 being operated. When the remaining storage position of the memory piece 21B is reached, it is returned to the slide-locked state and returned to the storage position before the change. Therefore, by subsequently returning the operation of the passenger lever 6, the release lever is returned to the initial position, and the slide rail device M is returned to the same state as the initial state.

  When the seat position is moved backward after the operation of the passenger lever 6 shown in FIG. 21, the head side link 22Ac of the trigger link 22A described above can be moved back to the passenger support position near the rearmost as it is. When the trigger link 22A is pressed from the front side to the locking surface portion 15A of the stopper bracket 15 described above with reference to FIG. 5 and operates in the same manner as shown in FIGS. 24 to 25, the seat position is slide-locked at that position.

Further, the loop handle 5 is operated from the initial state of FIG. 14 described above, and as shown in FIG. 34, the seat position is moved forward to the lock position (limit position P1: front most) on the frontmost end side in the lock region A1. Then, the engaging claws 21Ba2 on the front end side of the memory piece 21B are abutted and locked to the locking portion 21Ac of the memory rail 21A from the rear side. Accordingly, when the seat position is further moved forward to the overstroke area A2 from that state as shown in FIG. 35, the memory piece 21B locked by the contact with the locking portion 21Ac of the memory rail 21A described above remains. The follower member 38 slides forward on the memory piece 21B, and the trigger link 22A is pushed so as to be tilted forward from the contact point with the rear end of the raised portion 21Bb of the memory piece 21B. It will be tilted.

  Therefore, the seat position can be moved to the overstroke region A2 while the memory piece 21B remains in the slide position corresponding to the lock position (limit position P1: front most) on the foremost end side of the slide rail 10. After the operation of the loop handle 5 is temporarily stopped in the overstroke area A2, the memory position 21B is detected again by retreating the seat position by operating the getting-on / off lever 6 as shown in FIG. It can function as a state in which the body 22 and the operation mechanism 30 are effectively engaged.
