  BACKGROUND ART Conventionally, as a mechanism for connecting a vehicle seat to a floor so as to be slidable, there is known a mechanism described in Patent Document 1 below. In other words, it has a slide rail that can adjust the seat position by releasing the lock mechanism, and a memory mechanism that stores the position before the change of the seat position and allows the seat position to be returned to the storage position before the change. . The lock mechanism is held in a locked state in the initial state, and can be switched to a release state in which the seat position can be adjusted by operating a release lever. The memory mechanism is operated by a memory lever provided separately from the release lever described above.

  Specifically, the above-described memory mechanism performs the above-described unlocking operation of the lock mechanism by operating the above-mentioned memory lever, and leaves the memory member engaged at the slide position where the releasing operation was performed. , And other members are separated so that they can be moved in the sliding direction together with the vehicle seat. Then, the memory mechanism returns the seat position to the storage position before the change after the change of the seat position, so that the other members that move together with the vehicle seat are left in the memory position. In such a case, the lock mechanism is moved to return to the locked state. Normally, when the release lever is operated and the seat position is changed, the memory mechanism is operated so that the memory member is removed from the position storage state by the release lever, and the memory mechanism is operated with the change of the seat position. To change the storage location.

<< About schematic structure of sheet 1 >>
First, a 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. The seat 1 of this embodiment is configured as a driver's seat of a right-hand drive vehicle, as shown in FIGS. The seat 1 includes a seat back 2 serving as a backrest portion of a seated occupant, a seat cushion 3 serving as a seating portion, and a headrest 4 serving as a headrest portion. The seat cushion 3 is connected to a 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 of the seat cushion 3 via a recliner (not shown). Further, the headrest 4 is provided to be mounted on an upper portion of the seat back 2.

  Here, in the following description, the “sheet width direction” refers to the lateral width direction (left-right direction) of the sheet 1. Further, the term "vehicle width direction" refers to the lateral width direction (left-right direction) of the vehicle, and the term "inside in the vehicle width direction" refers to the left side of the seat 1, that is, the side with the passenger seat (not shown). In this case, "outside in the vehicle width direction" refers to the right side of the seat 1, that is, the side where a not-shown entrance door is located.

  In the initial state, the seat 1 described above is held in a state where the slides of the slide rails 10 are locked, so that the position in the front-rear direction on the floor F (hereinafter, “seat position”) is fixed. It is held as the state that was done. As shown in FIG. 4, the above-described slide rails 10 release the locked state of the slides all at once by the operation of raising the loop handle 5 provided at the lower front part of the seat cushion 3. The state can be switched to a state where the seat position can be adjusted. Then, each slide rail 10 is returned to the locked state again by returning the operation of the loop handle 5 after the adjustment of the seat position.

  Further, as shown in FIG. 1, each of the slide rails 10 described above can also be moved by the operation of pulling up the memory lever 6 provided on the outer side (right side) of the seat cushion 3 in the vehicle width direction. The locked state is released all at once. At this time, even if the operation of the memory lever 6 is returned, the slide rails 10 are kept in a state where their slides are unlocked by the operation mechanism 30 constituting the slide rail device M described later. Has become. After the operation of the memory lever 6, each slide rail 10 is in a state where the seat position can be freely moved, and the seat position is locked near the rear most indicated by the virtual line in FIG. 1 (solid line in FIG. 2). Unless the position is moved to either the position or the position before the change indicated by the solid line in FIG. 1 (the virtual line in FIG. 2), the unlocked state of those slides is maintained. I have.

  That is, when the locked state of the slides is released by the operation of the memory lever 6 described above, the respective slide rails 10 are operated by a memory mechanism 20 that configures a slide rail device M described later to operate the seat rails before the change of the seat position. As the state in which the position is stored, the seat position is the locked position near the rear moat indicated by a virtual line in FIG. 1 (solid line in FIG. 2) or the position before the change indicated by the solid line in FIG. 1 (virtual line in FIG. 2). , The state can be switched to a state in which the slide is basically locked (memory state). With such a configuration, each slide rail 10 is operated by operating the memory lever 6 from a state where the seat position is used at the driving position closer to the front side (solid line position in FIG. 1). It is possible to use the seat position by retracting the seat position at a stretch to a getting-on / off support position (a virtual line position in FIG. 1) where the getting-on / off operation can be easily performed in the vicinity of the rear moat, and once locked at that position.

  Further, each slide rail 10 operates the memory lever 6 again as shown in FIG. 2 from a state in which the slide is temporarily locked at the getting on / off support position (the imaginary line position in FIG. 1) near the rear moost. As a result, the seat position is basically locked only at one of the above-described entry / exit support position near the rear most (solid line position in FIG. 2) and the position before change (virtual line position in FIG. 2). State (memory state). Each slide rail 10 is configured as described above, so that the seat position is once locked at the above-mentioned getting on and off support position (solid line position in FIG. 2) near the rear moat, and then the memory lever 6 is reset. By performing the above operation, the seat position can be returned to the driving position (the imaginary line position in FIG. 2) before the change at once, and the seat position can be returned to the locked state. .

  To summarize the above flow, the seat position is moved backward to the temporary support position (movement from the solid line position to the imaginary line position in FIG. 1) by the operation of the memory lever 6 described above, and the seat position before the change is changed. The return movement to the driving position (movement from the solid line position to the virtual line position in FIG. 2) is performed according to the following procedure. First, as shown by the solid line in FIG. 1, the memory lever 6 is pulled up in a state where the seat 1 is at an arbitrary use position such as a driving position (circled numeral 1 in FIG. 1). Next, the seat position is retracted (the number 2 with a circle in FIG. 1), and the seat position is moved to a boarding / alighting support position (a virtual line position in FIG. 1) in the vicinity of the rear moat where the movement is locked. As a result, as shown by the circled numeral 3 in FIG. 1, the seat position is automatically locked at the entry / exit support position near the rear mast (the imaginary line position in FIG. 1). Is secured, and a state in which the getting on / off operation can be easily performed (a getting on / off support state) is achieved. Note that the boarding / alighting support position (the imaginary line position in FIG. 1) near the rear moat where the seat position is locked is set to a position where the seat back 2 substantially overlaps the B pillar BP of the vehicle in the front-rear direction. ing.

  Next, as shown by the solid line in FIG. 2, after the driver gets on the seat 1 from the state where the seat position is locked at the getting on / off support position near the rear moat by the above operation, the memory lever 6 is again turned on. A lifting operation is performed (circled number 4 in FIG. 2). Then, the seat position is advanced (circled numeral 5 in FIG. 2) and moved to a use position (a virtual line position in FIG. 2) such as a driving position before change in which the movement is locked. As a result, the seat position is automatically locked at the used position (the imaginary line position in FIG. 2) before the change, as indicated by the circled numeral 6 in FIG. The seat position can be easily returned to the storage position before the change without performing the adjustment.

  As shown in FIG. 3, each slide rail 10 described above has a loop handle at an arbitrary position in a state where the position before the change of the seat position is stored by operating the memory lever 6 (memory state). By performing the raising operation of 5, the operation of the operating mechanism 30 described later cancels the above-described unlocked and held state by the memory mechanism 20 so that the seat position can be returned to the locked state at that position. Has become. With this configuration, each slide rail 10 can be switched to a state (memory state) in which the seat position can be locked only at the two front and rear positions described above with reference to FIGS. Even if necessary, the user can operate the loop handle 5 to immediately cancel the memory state at that position and lock the seat position at that position (arbitrary position).

  In each of the drawings shown in FIGS. 1 to 3, the state in which the above-described seat 1 is in the memory state by the operation of the memory lever 6 is represented by a state in which the sheet 1 is lightly painted. The state in which the memory state is canceled by the operation of (1) is represented by a state in which the sheet 1 is not coated.

  Further, even if the memory state is canceled by the operation of the loop handle 5 described above with reference to FIG. 3, the slide rail 10 performs the above-described cancel operation by operating the memory lever 6 again. It returns to the memory state before it was written. With such a configuration, even if the memory state is once canceled by the operation of the loop handle 5 described above, each slide rail 10 can operate the memory lever 6 again to operate the memory rail 6. The state can be returned to the state before being canceled, and the seat position can be switched to a state in which the seat position can be returned to a use position (solid line position) such as a driving position before the change at a stretch.

<< Specific configuration of slide rail 10 >>
Hereinafter, specific configurations of the slide rails 10, the memory mechanism 20, and the operation mechanism 30 configuring the slide rail device M described above will be described in detail. First, the configuration of each slide rail 10 will be described with reference to FIGS. That is, each of the slide rails 10 includes a lower rail 11 attached to the floor F, an upper rail 12 attached to the lower rail 11 so as to be slidable in the front-rear direction, and attached to a lower portion of the seat cushion 3. And a lock spring 13 for locking the slide between the rails 11 and 12. The basic structure of each slide rail 10 is substantially the same on the left and right sides. Therefore, these detailed structures are represented by the structure of the inner slide rail 10 in the vehicle width direction shown in FIG. It will be explained. Here, the lock spring 13 corresponds to the “lock mechanism” of the present invention.

  As shown in FIG. 6, the lower rail 11 described above is formed by bending a single long plate of steel or the like in the front-rear direction of the vehicle into a substantially U-shape in the short direction. The above-described lower rail 11 has its front and rear ends fastened to the floor F by fastening members such as bolts (not shown), and is integrally fixed. The lower rail 11 is formed in a rail shape whose cross-sectional shape is substantially uniform in the front-rear direction. Specifically, the lower rail 11 has a bottom surface portion 11A disposed on the floor F with its surface facing upward, and an upper surface extending from both left and right side portions of the bottom surface portion 11A and facing inward to each other. It is formed in a cross-sectional shape having a pair of left and right lower-side fins 11B that are bent and extended in a letter shape. The lower rail 11 is configured such that the front and rear end portions of the above-described bottom surface portion 11A are respectively set on the floor F in a state of surface contact from above, and bolts and the like (not shown) inserted from above. It is in a state of being integrally fastened on the floor F by the fastening member.

  In the left and right lower fins 11B of the lower rail 11, the respective lock portions 13C of the lock springs 13 to be described later are inserted from below into the respective edges of the inverted U-shaped bent back ends. A lock groove 11C that can be engaged by pressing is formed. A plurality of these lock grooves 11C are formed at the same intervals in the front-rear direction so as to open downward, along each edge portion of each lower side fin portion 11B which is folded back and hangs down. It is in a formed state. The lock grooves 11C formed in the lower fins 11B are formed side by side at symmetrical positions.

  Like the above-mentioned lower rail 11, the upper rail 12 is formed by bending a long sheet of steel or the like in the front-rear direction of the vehicle into a substantially Ω shape in the short direction. The above-described upper rail 12 is inserted into the lower rail 11 from one of the opening ends in the longitudinal direction of the above-described lower rail 11, so that the upper rail 12 can be attached to the lower rail 11 so as to be slidable in the longitudinal direction. ing. Specifically, the upper rail 12 has a top plate portion 12A which is attached to the lower portion of the above-described seat cushion 3 with its cross-sectional shape facing upward and a left and right side portion of the top plate portion 12A. And a pair of left and right upper-side fins 12B extending downwardly from each other and bent back into a U-shape in opposition to each other.

  In the upper rail 12 described above, the respective upper and lower ends of the lower rail 11 that are bent back into a U-shape with respect to the lower rail 11 are opposite to the left and right lower fins 11B of the lower rail 11. It is inserted and assembled in the longitudinal direction so as to engage with each of the U-shaped bent shapes. By being assembled in this manner, the upper rail 12 is moved in the height direction with respect to the lower rail 11 by the engagement between the left and right upper fins 12B and the lower fin 11B. It is assembled in a state where it is prevented from coming off in the sheet width direction. More specifically, the upper rail 12 is prevented from rattling in the height direction and the seat width direction with respect to the lower rail 11 via a resin shoe and steel balls (rolling elements) (not shown) assembled between the upper rail 12 and the lower rail 11. It is also assembled so that it can slide smoothly in the front-rear direction.

  The lock spring 13 is formed by bending a single steel wire rod in the front-rear direction into a long and substantially U-shaped shape in plan view. The lock spring 13 has a rear end portion 13B formed as a folded portion that is folded in the sheet width direction and folded forward. The lock spring 13 is formed in such a manner that the lock spring 13 undulates in the middle portion between the pair of left and right wire portions extending forward from the above-mentioned rear end portion 13 </ b> B toward the outer sides in the seat width direction. The lock portion 13C is formed to have a bent shape. The front ends 13A of the respective wire portions of the lock spring 13 are each bent so as to extend stepwise to the upper front side.

  In the lock spring 13 described above, each bent portion of the front end portion 13A of each line portion is cut and raised inside from the side wall portion of the front region of each upper fin portion 12B of the upper rail 12 described above. Each hook piece 12Ba is set so as to be passed through from the rear side. With the above configuration, the front end 13A of each wire portion of the lock spring 13 is attached to each hooking piece 12Ba so as to be slidable in the front-rear direction and tiltable in the height direction. Further, the lock spring 13 is formed such that the folded portions on both corners of the rear end portion 13B are cut and raised inward from the side wall portions of the rear regions of the upper fin portions 12B of the upper rail 12, respectively. Each hook piece 12Bb is hooked and set from above. With the above configuration, the rear end portion 13B of the lock spring 13 is attached to each of the above-described hook pieces 12Bb so as to be connected to the pins so as to be axially rotatable in the height direction.

  The lock spring 13 has a pair of lock grooves 13C formed on the left and right upper side fins 12B of the upper rail 12 in the front-rear center region. It is assembled as a state that has been passed through from inside. Each of the above-mentioned through grooves 12C has a comb-shaped slit through which each of the lock portions 13C of the lock spring 13 inserted through them can be individually elongated toward the upper side. I have. As described above, the lock spring 13 has a both-ends support structure in which the front end portion 13A and the rear end portion 13B are pin-connected to each other so as to be rotatable in the height direction with respect to the upper rail 12. In the free state, the above-described lock portions 13C are held in the comb-like elongated slits in the through grooves 12C of the upper rail 12 from below by the restoring action of the spring urging force. It has become.

  In the lock spring 13 described above, the sliding position of the above-described upper rail 12 with respect to the lower rail 11 in the front-rear direction is formed in each of the above-described slits in the through-grooves 12C formed in each of the upper fins 12B and each of the lower fins 11B. The lock grooves 11C are aligned with each other in the vehicle width direction so that they pass from below through the slits in the through grooves 12C and the lock grooves 11C. By being passed in this way, the slide of the upper rail 12 in the front-rear direction with respect to the lower rail 11 is locked and held via the lock portions 13C of the lock spring 13 described above. The state in which the slide of the upper rail 12 with respect to the lower rail 11 is locked is a state in which the lock spring 13 is bent downward to be bent in each of FIGS. 11, 19, 36, 39, and 47. It is represented by a shape state restored to a shape extending substantially linearly in the front-rear direction.

  As shown in FIG. 13 and FIG. 20, the lock spring 13 described above is moved downward by the operation of the loop handle 5 (see FIG. 12) and the operation of the memory lever 6 (FIG. 20) when the memory link 34 constituting the operation mechanism 30 described later is operated. The lock portion 13C is pushed downward by the internal operation arm 39, which is pushed and turned by the memory link 34, to be pushed downward, so that the lock portion 13C is pushed from the lock groove 11C of the lower rail 11 (see FIG. 6). It is designed to be removed. By the above operation, the lock state of the slide of the upper rail 12 by the lock spring 13 is released. Therefore, the release operation allows the upper rail 12 to be slid in the front-rear direction with respect to the lower rail 11. Thereafter, when the operation state in which the lock spring 13 is depressed by the memory link 34 shown in FIGS. 13 and 20 is released, the lock spring 13 is again returned to the lower rail by the spring urging force as shown in each of FIGS. 11 is returned to a state (locked state) in which it enters the lock groove 11C (see FIG. 6).

  At this time, the sliding position where the upper rail 12 is moved is such that the lock groove 11C of the lower rail 11 is not located at a position where the lock portion 13C of the lock spring 13 is going to return to the upper side by the spring urging force, that is, the lock groove 11C. When the intervening shelf surface is located directly above, the lock portion 13C is returned only to a position where it comes into contact with the shelf surface, and the slide is not locked. However, by shifting the slide position of the upper rail 12 from the slide position to the front and rear sides, the lock portion 13C is aligned with the lock groove 11C of the lower rail 11, enters the lock groove 11C and locks.

  The above is the specific configuration of each slide rail 10 shown in FIG. Note that, among the slide rails 10, those arranged inside (left side) in the vehicle width direction are further assembled with a memory mechanism 20 and an operation mechanism 30, which will be described later. With the above configuration, the operation of releasing the lock of the lock spring 13 is performed on the inner slide rail 10 in the vehicle width direction by the operation of the loop handle 5 and the operation of the memory lever 6 via the operation mechanism 30 described later. I have. On the other hand, a release member 14 configured to release the lock of the lock spring 13 by operating the above-described loop handle 5 or the memory lever 6 is provided on the slide rail 10 disposed outside (right side) in the vehicle width direction. Are mounted on the upper rail 12.

  The release member 14 is configured so as to rotate integrally with a memory link 34 via a rod 32 constituting an operation mechanism 30 described later. With the above configuration, the release member 14 performs the operation of releasing the lock of the lock spring 13 on the same side in accordance with the operation in which the memory link 34 is pushed downward by the operation of the loop handle 5 or the operation of the memory lever 6 described above. It is configured as follows. With the above configuration, the operations of locking and releasing the slide rails 10 are simultaneously performed on the left and right by the operation of the loop handle 5 and the operation of the memory lever 6 at the same time.

  Further, a tension spring 15 is further hung between the upper rail 12 and the lower rail 11 on the slide rail 10 arranged on the outer side (right side) in the vehicle width direction. Due to the spring urging force exerted by the tension spring 15, a force is applied to both slide rails 10 in a direction in which the upper rail 12 is pushed forward with respect to the lower rail 11. Therefore, by releasing the locked state of the slide of each slide rail 10, the upper rail 12 can be slid to the front side with a small force with respect to the lower rail 11.

  The slide rail 10 on the inner side (left side) in the vehicle width direction has a seat position where the slide rail 10 is in a memory state by operating the memory lever 6 described above, and the seat position is in the vicinity of the rear mast (a virtual position in FIG. 1). (A line position), a stopper bracket 16 for restricting the movement by abutting on the stopper bracket 16 is attached. As shown in FIGS. 5 and 6, the stopper bracket 16 has a configuration in which a stopper link 16A is rotatably attached to a plate made of steel or the like bent in an L-shape. The above-described stopper bracket 16 is externally attached to the lower rail 11 such that the bottom plate portion and the upright plate portion are along the bottom surface portion 11A of the lower rail 11 and the outer surface of the inner (right) lower side fin portion 11B. It is assembled as. The upright portion of the stopper bracket 16 has a shape that projects straight up to a position protruding above the outer surface of the lower fin 11B of the lower rail 11.

  The stopper link 16A is rotatably connected to the above-described front upper end portion of the stopper bracket 16 by a shaft pin 16A1 that turns the axis in the vehicle width direction. As shown in FIG. 30, the stopper link 16A is always shown around the shaft pin 16A1 with respect to the stopper bracket 16 by the urging force of a spring (not shown) attached to the stopper bracket 16 as described above. The state in which the counterclockwise rotating force is applied is a state in which it is pressed against the locking piece 16B formed on the stopper bracket 16 and locked. With the above configuration, as shown in FIGS. 32 to 35, when the slide rail 10 is switched to the memory state by operating the memory lever 6 and the seat position is retracted to the boarding / alighting support position near the rear most, as shown in FIGS. A holding release operation link 22A of the trigger 22, which will be described later, is pressed from the front side, and the holding release operation link 22A is pushed and turned from the rear side to lock the slide rail 10 at that position.

  As shown in FIGS. 15 to 17, the stopper link 16A pushes the holding release operation link 22A from the front side when the slide rail 10 is retracted toward the rear most position by operating the loop handle 5 as described above. The holding release operation link 22A is pushed and turned from the rear side, and since the holding release operation link 22A is configured to slip through the stopper link 16A to the rear side without locking the slide rail 10, the above-described operation is performed. , The front / rear positional relationship with the holding release operation link 22A is switched (see FIG. 17). That is, when the slide rail 10 is moved backward by the operation of the loop handle 5 toward the rear most position, the stopper link 16A does not function to restrict the backward movement of the slide rail 10, and the slide rail 10 slides to the rear most position. Is tolerated.

  Then, as shown in FIG. 18, the slide rail 10 moves forward and the holding release operation link 22A pushes the stopper link 16A from the rear side from the state in which the front-rear positional relationship with the holding release operation link 22A is switched. When it is applied, the holding release operation link 22A rotates in the clockwise direction around the shaft pin 16A1 in the form of being pushed from behind by the holding release operation link 22A so as not to hinder the return movement of the holding release operation link 22A to the front side. To escape to. Then, the stopper link 16A is returned to the initial position where the stopper release operation link 22A is pushed against the locking piece 16B of the stopper bracket 16 again by the spring urging force when the holding release operation link 22A passes through the stopper link 16A. It has become.

<< Specific Configuration of Memory Mechanism 20 >>
Next, a specific configuration of the memory mechanism 20 will be described with reference to FIGS. As shown in FIGS. 5 and 6, the memory mechanism 20 is roughly composed of a memory body 21 mounted on the lower rail 11 and a trigger 22 mounted on the upper rail 12. As shown in FIGS. 30 to 31, when the seat position is changed by operating the memory lever 6, the former memory body 21 remains at the fixed position on the lower rail 11 to change the position before the change of the seat position, as shown in FIGS. It functions as a member for storing.

  As shown in FIGS. 32 to 35, the latter trigger 22 causes the seat position to retreat to the above-mentioned getting on / off support position (the imaginary line position in FIG. 1) by operating the above-mentioned memory lever 6, so that the above-mentioned stopper bracket The stopper 16 is rotated by being pressed against the 16 stopper links 16A from the front side, and locks the seat position at that position. Also, the trigger 22 is actuated when the seat position is advanced from the above-mentioned getting on and off support position (the imaginary line position in FIG. 1) to the previously stored driving position or the like by the operation of the memory lever 6 before the change. The memory body 21 described above with reference to FIGS. 30 to 31 is rotated by being pressed against the memory body 21 from the rear side, and locks the seat position at that position in the same manner as the state shown in FIGS. 32 to 35 described above. It is what you do.

  As shown in FIGS. 15 to 17, the trigger 22 is moved backward by the operation of the loop handle 5 described above to move the seat position beyond the above-described getting on / off support position (the imaginary line position in FIG. 1) toward the rear most position. At this time, even if the sheet is rotated by being pressed against the stopper link 16A of the stopper bracket 16 from the front side, the seat position does not function to lock the position at that position. Function to allow it to pass through to the rear.

<< Specific Configuration of Memory Body 21 >>
Subsequently, a specific configuration of the above-described memory body 21 will be described with reference to FIGS. 6 and 10. The memory body 21 is configured to include a memory plate 21A that is long in the front-rear direction and a memory slider 21B that is slidably mounted on the memory plate 21A in the front-rear direction. Here, the memory slider 21B corresponds to the “memory member” of the present invention.

  The former memory plate 21A has a shape in which a single long plate material such as steel in the front-rear direction is bent into a substantially U-shape in the short direction. The above-mentioned memory plate 21A is provided on the bottom surface 11A of the above-mentioned lower rail 11 in a state where a plurality of front and rear portions are screwed together and fixed integrally. The above-described memory plate 21A has a shape in which each edge portion bent in a substantially U-shaped cross section is further bent in an eaves shape toward inward sides. With the above configuration, the memory plate 21A can be slid in the front-rear direction so that the memory slider 21B is not peeled off in the height direction by inserting the memory slider 21B into the inside from either of the front and rear opening ends on the left and right sides thereof. A guide rail 21Aa that can be supported on the guide rail 21Aa is formed. The space between the top plate portions projecting like an eave from the upper edge of each guide rail 21Aa of the memory plate 21A is formed in a shape extending in a streak shape in the front-rear direction. Rectangular memory grooves 21Ab penetrating in the height direction are formed at equal intervals in the front-rear direction at a plurality of locations in the front-rear direction across the portion.

  The memory slider 21B is formed of a substantially flat member. The memory slider 21B is provided so as to be inserted into the memory plate 21A from one of the front and rear opening ends and slidably supported in the front and rear direction. At the front end of the memory slider 21B described above, a hook 21Ba in the form of a hook that protrudes toward the front lower side is provided at a location where the memory plate 21A comes out upward from the gap between the top plates of the memory plate 21A. , Are rotatably connected to each other by a shaft pin 21Ba1 whose axis is directed in the vehicle width direction.

  Normally, a force in the direction of rotating the hook 21Ba forward around the shaft pin 21Ba1 is applied by the urging force of the flat plate-shaped leaf spring 21Bb hooked between the hook 21Ba and the memory slider 21B. It is in a state. With the above-described configuration, the hook 21Ba normally receives a force such that the front lower end thereof is pressed against the top plate portion of the memory plate 21A from above, thereby aligning the hook 21Ba with one of the memory grooves 21Ab of the memory plate 21A. As a result, the memory groove 21Ab is held in a state of entering the memory groove 21Ab. When the hook 21Ba enters the memory groove 21Ab, the slide of the memory slider 21B in the front-rear direction with respect to the memory plate 21A is held in a locked state. Here, the hook 21Ba corresponds to the “moving part” of the present invention, and the leaf spring 21Bb corresponds to the “interlocking operation member” of the present invention.

  The above-described leaf spring 21Bb is diagonally bridged in a rearward downward shape between a rear end portion extending in a manner of jumping upward and rearward from the hook 21Ba and a rear end portion of the memory slider 21B. The spring 21 biases the hook 21Ba to rotate forward. An engagement hole 21Bb1 that penetrates in the height direction is formed at a middle part of the leaf spring 21Bb in the front-rear direction. The engagement hole 21Bb1 is formed at the lower end of the release link 35 when the release link 35 constituting the operation mechanism 30 is pushed downward by the operation of the loop handle 5 as described later with reference to FIG. It functions as a hole for receiving the engaged engagement / disengagement piece 35A from above and bringing the release link 35 into a state of being integrally engaged with the memory slider 21B in the front-rear direction. Here, the engagement hole 21Bb1 corresponds to the "restriction portion" of the present invention.

  Further, the leaf spring 21Bb is deflected downward by the engagement / disengagement piece 35A while the engagement / disengagement piece 35A of the release link 35 enters the above-described engagement hole 21Bb1, and moves around the hook 21Ba backward. It is designed to be operated so as to draw in. By the above operation, the hook 21Ba is pulled out from the state where it has entered into any one of the memory grooves 21Ab of the memory plate 21A, and the locked state of the slide of the memory slider 21B with respect to the memory plate 21A is released. When the operation state in which the release link 35 is depressed is released, the hook 21Ba is returned to a state in which the hook 21Ba has entered the corresponding memory groove 21Ab of the memory plate 21A with the restoration of the leaf spring 21Bb. It has become.

  The position at which the slide of the memory slider 21B with respect to the memory plate 21A is locked, that is, the position at which the hook 21Ba can enter any one of the memory grooves 21Ab is determined by the slide of the upper rail 12 with respect to the lower rail 11. The position is set to a position corresponding to a position where the lock spring 13 is inserted into any one of the lock grooves 11C of the lower rail 11. That is, the lock pitch of the memory slider 21B in the sliding direction with respect to the memory plate 21A is set to the same pitch as the lock pitch of the upper rail 12 in the sliding direction with respect to the lower rail 11.

  Further, the engagement holes 21Bb1 formed in the leaf spring 21Bb described above are, in detail, formed side by side at two positions before and after the leaf spring 21Bb. The engagement hole 21Bb1 formed on the rear side is normally released when the loop handle 5 is operated and the release link 35 is pushed down from a position immediately above the same as described later with reference to FIG. The link 35 functions as a hole for receiving the engagement / disengagement piece 35A. As shown in FIGS. 42 to 45, the rear engagement hole 21 </ b> Bb <b> 1 is pushed down by the operation of the loop handle 5 at a position where the release link 35 is separated from the position immediately above the rear link to the rear side. When an operation is performed on the leaf spring 21Bb that allows the rider to ride on the leaf spring 21Bb from the rear side in the operating state, the hole for receiving the engagement / disengagement piece 35A of the release link 35 that slides on the leaf spring 21Bb from the rear side may be used. It is working.

  On the other hand, as shown in FIG. 31, the front engagement hole 21Bb1 is moved forward from the movement position where the seat position is retracted from the previous storage position by the operation of the memory lever 6 toward the previous storage position at a high speed. When an abnormal operation such as returning to the normal position is performed, as shown in FIG. 46, even if the trigger 22 described later is pressed against the memory slider 21B from the rear side to lock the seat position, as will be described later with reference to FIG. Even if the lock spring 13 is locked at the position where the tooth jumps forward by one pitch due to the return speed of the lock spring 13 not being in time, the disengagement piece 35A of the release link 35 is pushed down by operating the loop handle 5 at that position. It is formed in a position that can accept the operation. With the above-described configuration, even after the above-described tooth jump phenomenon occurs, the operation of setting the release link 35 to the state integrally engaged with the memory slider 21B in the front-rear direction by operating the loop handle 5 can be performed as usual. It has become.

<< Specific configuration of trigger 22 >>
Next, a specific configuration of the above-described trigger 22 will be described with reference to FIGS. The trigger 22 includes a holding release operation link 22A mounted on a base bracket 31 on the upper rail 12, which will be described later, and a power transmission plate mounted on the base bracket 31 and rotated by receiving power transmitted from the holding release operation link 22A. 22B, and an operation cam 22C assembled to the power transmission plate 22B. The holding release operation link 22A is formed of a single plate material such as steel that is long in the height direction facing the vehicle width direction. The holding release operation link 22A is configured such that an intermediate portion near the lower end side in the height direction is rotatable toward an inner surface of a rear end portion of the base bracket 31 described later by an axis pin 22Aa for turning an axis in the vehicle width direction. It is provided as a pin-connected state. The above-mentioned holding release operation link 22A is normally moved downward with respect to the base bracket 31 around the shaft pin 22Aa by the urging force of a spring (not shown) attached to the above-mentioned base bracket 31. A force is applied in a direction to rotate the extending leg piece 22Ab forward.

  With the above configuration, as shown in FIG. 10, when the memory slider 21B is adjacent to the front position in the free state, the holding release operation link 22A pushes the leg piece 22Ab to the memory slider 21B from the rear side. It is configured to be held in a state of the standing posture applied. As shown in FIG. 30 to FIG. 31, when the seat position is retracted by operating the memory lever 6 while leaving the memory slider 21B, the holding release operation link 22A causes the leg piece 22Ab to move rearward from the memory slider 21B. When separated, the above-mentioned spring biasing force keeps the leg piece 22Ab in an oblique posture with the leg piece 22Ab slightly raised to the front side. The holding release operation link 22A pushes the power transmission plate 22B by the rotation, and the power transmission plate 22B is pressed against a locking piece 31C of the base bracket 31, which will be described later, from the front side. It is configured to be kept in a state of being inclined obliquely (see FIG. 31).

  As shown in FIGS. 7 and 9 to 10, a slide pin 22Ac for directing an axis in the vehicle width direction is provided at an upper end portion of the holding release operation link 22A in a protruding state. The slide pin 22Ac is inserted in a vehicle width direction into a long hole 22Bb formed in a power transmission plate 22B described later, and as shown in FIGS. 15 to 17 and FIGS. With the rotation of 22A, the inside of the same long hole 22Bb can be slid in the front-back direction. Further, a stopper pin 22Ad for directing an axis in the vehicle width direction is provided at a middle portion of the holding release operation link 22A in a protruding state. As shown in FIGS. 15 to 17 and FIGS. 30 to 35, the stopper pin 22 </ b> Ad is pressed from the front side against a stopper link 16 </ b> A provided on the stopper bracket 16 by retreating the seat position, and The function is such that the holding release operation link 22A is pushed down to the front side around the shaft pin 22Aa as the movement progresses.

  As shown in FIGS. 9 and 10, the power transmission plate 22B is formed of a single plate material such as steel facing the vehicle width direction. The power transmission plate 22B is provided in a state in which a rear upper corner portion is rotatably pin-connected to an inner surface of a rear end portion of a base bracket 31, which will be described later, by a shaft pin 22Ba that points an axis in the vehicle width direction. Have been. The power transmission plate 22B is formed with a long hole 22Bb having a shape extending in the rotation direction and the radial direction about the shaft pin 22Ba. The slide pin 22Ac of the above-described holding release operation link 22A is inserted into the long hole 22Bb, and the slide pin 22Ac slides in the long hole 22Bb by the rotation of the holding release operation link 22A. With the above configuration, the rotation posture of the power transmission plate 22B is controlled by the rotation posture of the holding release operation link 22A. That is, the rotation of the power release plate 22B is stopped by stopping the rotation posture of the holding release operation link 22A, and the power transmission plate 22B is pushed by the holding release operation link 22A by rotating the holding release operation link 22A. Can change the rotation posture.

  More specifically, the above-described elongated hole 22Bb is formed by a power transmission region 22Bb1 extending straight in the radial direction about the shaft pin 22Ba of the power transmission plate 22B, and a rotational direction from a radially outer end of the power transmission region 22Bb1. And a relief region 22Bb2 that extends in a curved manner in an arc shape. Since the former power transmission region 22Bb1 has a shape that extends straight in the radial direction around the shaft pin 22Ba, the inside of the power transmission region 22Bb1 is rotated by the rotation of the holding release operation link 22A as shown in FIGS. When the slide pin 22Ac passes, the power is efficiently transmitted in the rotational direction from the slide pin 22Ac, and the power transmission plate 22B functions to rotate efficiently. Also, as shown in FIG. 16, the slide area 22Bb2 is formed so that the slide area 22Bb2 passes through the slide area 22Bb2 so as to be curved into an arc shape centered on the shaft pin 22Aa of the holding release operation link 22A. It is shaped. With the above-described configuration, the escape area 22Bb2 is in a state where the slide pin 22Ac is passed through the inside thereof, so that even if the slide pin 22Ac slides due to the rotation of the holding release operation link 22A in the escape area 22Bb2, power transmission is performed. The function is such that the rotation of the holding release operation link 22A is released without transmitting power to the plate 22B.

  As shown in FIGS. 9 and 10, the operation cam 22C is formed of a substantially plate-shaped member whose surface faces in the vehicle width direction. The operation cam 22C is provided at the upper front corner of the above-described power transmission plate 22B so as to be rotatably connected to a shaft pin 22Ca that is oriented in the vehicle width direction. The operation cam 22C normally exerts a counterclockwise rotating force on the power transmission plate 22B by the urging force of a spring (not shown) attached between the operation cam 22C and the power transmission plate 22B. It is in a state where it was done. With the configuration described above, in the free state, the operating cam 22C is in the same direction as the locking piece 22Cb extending from the rear portion thereof is brought into contact with the locking piece 22Bc formed on the power transmission plate 22B from below. Is held as a state in which the rotational movement is restricted.

  As shown in FIG. 10, when the memory slider 21B is positioned adjacent to the front position of the holding release operation link 22A in the free state, the operation cam 22C extends toward the front side as shown in FIG. However, the release holding member 36 constituting the operation mechanism 30 described later is held in a state positioned above the kicked piece 36D. However, as shown in FIGS. 30 to 31, the operation cam 22 </ b> C is rotated in such a manner that the holding release operation link 22 </ b> A is separated rearward from the memory slider 21 </ b> B and tilted rearward by urging. The operation projection 22Cc on the distal end side is moved so as to reverse the positional relationship in such a manner that the operation projection 22Cc slips below the kicking piece 36D of the release holding member 36.

  That is, as shown in FIG. 30, the holding release operation link 22A is separated from the memory slider 21B to the rear side and rotated so as to be tilted rearward by the urging, whereby the slide pin 22Ac of the holding release operation link 22A is rotated. As a result, the power transmission plate 22B is rotated counterclockwise in the figure around the shaft pin 22Ba. As a result, the operation projection 22Cc on the distal end side of the operation cam 22C connected to the power transmission plate 22B is pressed against the kicking piece 36D of the release holding member 36 from above, and the operation projection 22Cc resists the spring urging force. While being rotated around the shaft pin 22Ca in the clockwise direction in the figure, it is kicked and slips below the piece 36D. Then, as shown in FIG. 31, the operation protrusion 22Cc slips below the kicking piece 36D of the release holding member 36, and is again brought into contact with the locking piece 22Bc of the power transmission plate 22B by the spring urging force. It is adapted to be returned to a position where it is applied and locked from below.

  The operation cam 22C is in a state in which the operation protrusion 22Cc on the distal end side of the operation cam 22C has slipped below the kicked piece 36D of the release holding member 36 as described above. As shown in FIG. 35, the stopper link 16A is pressed from the front side or the memory slider 21B described in FIG. 30 is pressed from the rear side in the counterclockwise direction around the shaft pin 16A1. By being pushed around, it is rotated integrally with the power transmission plate 22B so as to be raised up frontward about the shaft pin 22Ba, and the operation projection 22Cc on the tip side is kicked by the release holding member 36. And pressed against the piece 36D from below (see FIG. 33). As shown in FIGS. 34 to 35, the operation cam 22C pushes the kicking piece 36D of the release holding member 36 from the lower side by the operation protrusion 22Cc on the tip side of the operation cam 22C from the above state to move the release holding member 36. The operation mechanism 30 can be rotated around the shaft pin 36A in the counterclockwise direction in the figure to move the operation mechanism 30 so as to lock the seat position at that position as described later (see FIG. 36).

  As shown in FIG. 6, the above-described trigger 22 is configured such that the underbody structure such as the leg piece 22Ab of the above-described holding release operation link 22A is formed in a long rectangular shape formed on the top plate 12A of the upper rail 12 in the front-rear direction. It is set in a state where it is inserted from above into the through hole 12Ab of the shape and enters the space in the rail between the upper rail 12 and the lower rail 11.

<< Specific Configuration of Operation Mechanism 30 >>
Next, a specific configuration of the operation mechanism 30 will be described with reference to FIGS. As shown in FIGS. 7 to 9, the operation mechanism 30 is integrally attached to a base bracket 31 serving as a base, a rod 32 rotatably connected to the base bracket 31 with a pin, and the loop handle 5. Arm 33, which is rotatably operated about a rod 32 as an axis, a memory link 34, which is connected to the base bracket 31 by a pin so as to be rotatable coaxially with the rod 32, and a base bracket which is arranged side by side with the memory link 34. A release link 35 rotatably pin-connected to the rod 32 with respect to the rod 32; a release holding member 36 attached to the release link 35 and configured to be disengageable from the memory link 34; An L-shaped link 37 which is rotatably connected to a pin and is rotated by operating the memory lever 6; A transmission link 38 rotatably connected to a pin 31 and connected to the above-described memory link 34 by a gear so as to be capable of transmitting power, and a transmission link 38 attached to the top plate 12A of the upper rail 12 from below as shown in FIG. And an internal operation arm 39 which is rotatably connected to a pin in a space in the rail of the upper rail 12. Here, the memory link 34 corresponds to a “memory operation member” of the present invention, and the release link 35 corresponds to a “release operation member” of the present invention.

  As shown in FIGS. 7 and 8, the base bracket 31 is formed of a single sheet material such as steel that is long in the front-rear direction and faces in the vehicle width direction. As shown in FIG. 8, the base bracket 31 has a shape in which a lower edge portion is bent inward (right side) in a seat width direction from a front portion to an intermediate portion, and the upper rail is shown in FIG. It is provided as a state in which it is applied to the top plate portion 12A and is integrally fixed by fastening with a fastening member such as a bolt.

  As shown in FIG. 8, a locking piece 31A bent inward in the seat width direction is also formed on the upper edge of the front region of the base bracket 31. As shown in FIG. 10, the locking piece 31A is located immediately above an eaves piece 35C formed on an upper edge portion of a release link 35, which will be described later, and the release link 35 is centered on the rod 32 by a spring urging force. It functions as a restricting portion that restricts the movement moved in the counterclockwise direction in the figure by contact from above. As shown in FIG. 11, the locking piece 31A restricts the movement of the L-shaped link 37 to be described later, which is moved counterclockwise around the shaft pin 37A by the spring urging force, by contact from the front side. It also functions as a regulating unit.

  As shown in FIG. 8, a locking piece 31C bent inward in the seat width direction is also formed on the lower edge of the rear region of the base bracket 31. As shown in FIG. 31, the locking piece 31C is moved by the rotation of the holding release operation link 22A so that the holding release operation link 22A is separated from the memory slider 21B to the rear side and is tilted to the rear side by urging. Functions as a restricting portion that restricts the movement of the shaft pin 22Ba in the counterclockwise direction in the figure by abutting from the rear side.

  As shown in FIGS. 5 to 9, the rod 32 is formed of a single circular steel tube whose axis is directed in the vehicle width direction. The rod 32 has an operation shaft 32A integrally attached to an inner end in the vehicle width direction, and is inserted into the front region of the base bracket 31 from the outside in the vehicle width direction via the operation shaft 32A. It is in a rotatably pin-connected state. The outside (right side) end of the rod 32 in the vehicle width direction is integrally connected to the release member 14 described above with reference to FIG.

  As shown in FIGS. 7 to 9, the release arm 33 is formed of a single plate material such as steel, which is elongated in the front-rear direction. The release arm 33 is assembled so as to be rotatably supported on the rod 32 by passing the rod 32 in the vehicle width direction at an intermediate position in the front-rear direction. One end of the above-described loop handle 5 is integrally welded to a portion of the release arm 33 that extends forward from an intermediate position where the release arm 33 is passed through the rod 32. The portion of the release arm 33 that extends rearward from the midpoint where the release arm 33 is passed through the rod 32 has a shape that is bent in a crank shape inward (left side) in the vehicle width direction and extends rearward. It has been.

  As shown in FIG. 8, the release arm 33 is located at a position directly above a pressure receiving piece 35D formed on a lower edge portion of a release link 35 described later and protruding outward (right side) in a vehicle width direction, and a release holding described later. It is arranged so as to extend to the rear side through the pressure receiving piece 36C formed on the member 36 and protruding outward in the vehicle width direction, and to the rear side. The release arm 33 is normally moved around the rod 32 with respect to the base bracket 31 by the urging force of a spring (not shown) attached between the loop handle 5 and the skeleton of the seat cushion 3 (not shown). It is in a state where a rotating force is applied in a direction of lifting the portion extending to the side. With the configuration described above, in the free state, the release arm 33 is held in a state where the loop handle 5 is pulled down, and is separated upward from the pressure receiving piece 36C of the release holding member 36 and the pressure receiving piece 35D of the release link 35. The state is maintained.

  The release arm 33 is operated such that the portion of the loop handle 5 extending rearward from the rod 32 is pushed down by the operation of lifting the loop handle 5 around the rod 32. By the above operation, the release arm 33 is pressed against the pressure receiving piece 36C of the release holding member 36 and the pressure receiving piece 35D of the release link 35 from above as shown in FIG. Has become. More specifically, the release arm 33 described above contacts the pressure receiving piece 36C of the release holding member 36 and the pressure receiving piece 35D of the release link 35 in the following order by operating the loop handle 5 to be lifted, and these are brought into contact with each other. It is designed to push down.

  That is, as shown in FIG. 10, the release arm 33 has a positional relationship in which the pressure receiving piece 36 </ b> C of the release holding member 36 and the pressure receiving piece 35 </ b> D of the release link 35 are generally aligned in the front-rear direction at normal times. As shown in FIG. 12, when the loop handle 5 is pulled up, the loop handle 5 is pressed almost at the same time to push them downward. However, the release arm 33 is in an operating state in which the pressure receiving piece 36C of the release holding member 36 is raised to a position higher than the pressure receiving piece 35D of the release link 35 as shown in FIG. 37, the operation of pulling up the loop handle 5 first pushes the release holding member 36 downwardly before hitting the pressure receiving piece 36C of the release holding member 36, as shown in FIG. 38, the pressure receiving piece 36C of the release holding member 36 is brought into a position substantially aligned with the pressure receiving piece 35D of the release link 35 by the above operation, as shown in FIG. Also hit by 35D, both are pushed down simultaneously.

  In this manner, when the release arm 33 pushes down the pressure receiving piece 35D of the release link 35 described above, at least the pressure receiving piece 36C of the release holding member 36 is pushed down from a high position, and the release arm 33 is released. After releasing the holding state of the memory link 34 by the holding member 36 at the release operation position, the operation of pushing down the release link 35 is performed. With this configuration, the release arm 33 further forcibly moves the memory link 34 held at the position where the release operation is performed via the release holding member 36 in the release operation direction as shown in FIG. The operation of pushing and turning is not performed, so that each member is not overloaded.

  As shown in FIGS. 7 to 9, the memory link 34 is formed of a single sheet material such as steel that is long in the front-rear direction and faces in the vehicle width direction. The above-mentioned memory link 34 is in a state in which an operation shaft 32A integrally attached to an end of the above-described rod 32 in the front region thereof is passed from the outside (right side) in the vehicle width direction and integrally connected. The base bracket 31 is rotatably pin-connected to the inner surface of the front region of the base bracket 31 via the operation shaft 32A. Further, a release piece 34A protruding downward is formed in a rear area where the rod 32 of the memory link 34 extends rearward from the front area where the rod 32 is passed. .

  The above-described release piece 34A is inserted from above into a through hole 12Aa formed in the top plate 12A of the upper rail 12 described above with reference to FIG. 6, and is located immediately above the internal operation arm 39 assembled in the upper rail 12. It is in a state of being arranged so as to face (see FIG. 11). The release piece 34A is pushed by turning the memory link 34 downward as shown in FIGS. 13 and 20 by operating the loop handle 5 described above with reference to FIG. 12 or the memory lever 6 described later with reference to FIG. A function of contacting each lock portion 13C of the lock spring 13 from above through the above-described internal operation arm 39 to push and deflect them downward to be removed from the lock groove 11C of the lower rail 11 (see FIG. 6). It is supposed to.

  As shown in FIGS. 9 and 10, in the rear region of the memory link 34 described above, a vertically long shape curved into a substantially arc shape drawn around the axis center of the operation shaft 32 </ b> A which is the rotation center of the memory link 34. Is formed in a shape penetrating in the vehicle width direction. The through hole 34B is provided with a holding operation pin 36B projecting inward (left side) in the vehicle width direction from a release holding member 36 described later rotatably attached to an inner surface (right side) of a release link 35 described later. In a state in which the release holding member 36 is passed through the holding operation hole 35B formed in the release link 35 from the outside in the vehicle width direction, it functions as a hole that regulates the rotation range of the release holding member 36. In a hole region on the upper half side of the through hole 34B, there is formed a drawing hole 34Ba whose hole shape is extended so as to partially swell greatly to the rear side. Similar to the outer peripheral surface of the through hole 34B, the drawing hole 34Ba has a shape in which an outer peripheral surface on a radially outer side centered on the operation shaft 32A is curved into a substantially arc shape centered on the operation shaft 32A. It is formed.

  As shown in FIG. 10, the memory link 34 described above is normally moved around the operation shaft 32 </ b> A with respect to the base bracket 31 by the urging force of a spring (not shown) attached between the memory bracket 34 and the base bracket 31. It is in a state where a force that rotates in the counterclockwise direction in the figure is applied. With the above configuration, in the free state, the memory link 34 has an upper edge portion formed on the upper edge portion of the base bracket 31 via an eave piece 35C formed on the release link 35 described later. It is in a state where it is pressed against the stopper 31A from below and held in a state where movement is restricted.

  As shown in FIG. 12, the above-mentioned memory link 34 is provided with an eaves piece of the above-described release link 35 by an operation in which a later-described release link 35 is pushed down clockwise around the operation shaft 32A by operating the loop handle 5. 35C is operated so as to be pushed down. As shown in FIG. 20, the memory link 34 includes a transmission link 38, which will be described later, connected to be engaged with a gear 34C (external teeth) formed on the outer peripheral surface of the memory link 34 via an L-shaped link 37. The rotation operation by the operation of the lever 6 also causes the rotation operation in the clockwise direction in the figure around the operation shaft 32A similarly to the above. As a result of these rotation operations, the memory link 34 slides such that the release piece 34A formed at the lower end of the memory link 34 pushes and deflects each lock portion 13C of the lock spring 13 downward via the internal operation arm 39 as described above. The locked state of the slide of the rail 10 is released.

  As shown in FIGS. 7 to 9, the release link 35 is formed of a single sheet material such as steel that is long in the front-rear direction and faces in the vehicle width direction. The above-described release link 35 is in a state in which an operation shaft 32A integrally attached to an end of the above-described rod 32 is rotatably connected to the front region thereof from the outside (right side) in the vehicle width direction. The base bracket 31 is rotatably pin-connected to the inner surface of the front region of the base bracket 31 via the operation shaft 32A. The release link 35 is arranged side by side on the inner surface side (right side) of the memory link 34 arranged on the inner surface side of the base bracket 31 described above, and is coaxial with the memory link 34 (operation shaft 32A). It is provided in a rotatable state.

  As shown in FIG. 10, the release link 35 is always shown around the operation shaft 32 </ b> A with respect to the base bracket 31 by the urging force of a spring (not shown) attached to the base bracket 31 described above. It is in a state where a force that rotates counterclockwise is applied. With the above configuration, in the free state of the release link 35, the eaves 35 </ b> C formed by being bent inward (left side) in the vehicle width direction at the upper edge portion of the rear region are formed on the base bracket 31 described above. The locking piece 31A is pressed from below to be held in a state where movement is restricted.

  A disengagement piece 35A protruding downward is formed in a rear region that extends rearward from a front region of the release link 35 that is passed through the rod 32. The above-mentioned engagement / disengagement piece 35A is inserted from above into a through hole 12Aa formed in the top plate portion 12A of the upper rail 12 described above with reference to FIG. 6, and faces a position directly above the memory body 21 assembled on the lower rail 11. It is in a state where it is arranged as follows. More specifically, as shown in FIG. 10, the engagement piece 35A is in a state where the seat position is in the storage position before the change, that is, the holding release operation link 22A constituting the trigger 22 of the memory mechanism 20 is connected to the memory slider 21B. When the memory slider 21B is pressed in a standing posture adjacent to the rear side, the memory slider 21B is located immediately above the leaf spring 21Bb.

  As shown in FIG. 12, when the release link 35 is pushed down by the operation of the loop handle 5, the lower end portion of the engagement / disengagement piece 35 </ b> A is formed on the rear side of the leaf spring 21 </ b> Bb. An operation is performed so as to be pushed into the engagement hole 21Bb1. By the pushing operation, the engagement / disengagement piece 35A pushes and deflects the above-described leaf spring 21Bb downward, and removes the hook 21Ba from the memory groove 21Ab of the memory plate 21A. The engagement piece 35A is integrated with the memory slider 21B in the front-rear direction via the leaf spring 21Bb by entering the engagement hole 21Bb1.

  Further, the release link 35 is operated to be pushed downward as described above, and at the same time, the memory link 34 described above is operated to be pushed downward by its eaves 35C, as shown in FIG. Thus, the locked state of the slide of the slide rail 10 by the lock spring 13 is released. Accordingly, as shown in FIG. 15, the seat position is retracted while the operating state of the release link 35 is maintained, so that the release link 35 retracts the memory slider 21B together with the memory slider 21B so as to pull the memory slider 21B backward. Can be moved. Also, at the time of forward movement, the memory slider 21B can be moved forward together with the release link 35 pulling the memory slider 21B forward. As a result, the memory slider 21B is moved in the front-rear direction to a position corresponding to the position after the change of the seat position in accordance with the movement of the seat position.

  When the operation of the loop handle 5 is returned and the operation of the release link 35 is returned, the engagement piece 35A is detached from the engagement hole 21Bb1 of the memory slider 21B as shown in FIG. The state in which the leaf spring 21Bb is pressed and bent is released. Thus, the hook 21Ba is returned to a state (locked state) in which the hook 21Ba enters the corresponding memory groove 21Ab of the memory plate 21A again by the spring biasing force of the leaf spring 21Bb. At the same time, as shown in FIG. 11, the memory link 34 is also pulled back upward, and the slide rail 10 is returned to the slide locked state by the restoring deformation of the lock spring 13.

  As shown in FIGS. 9 and 10, a rear area of the above-described release link 35 is provided around a shaft center of a shaft pin 36 </ b> A which is a rotation center of a release holding member 36 described later connected to the release link 35. The holding operation hole 35B curved in a substantially arc shape to be drawn penetrates in the vehicle width direction and is formed. As shown in FIG. 10, when the release link 35 and the memory link 34 are held at the initial position, the holding operation hole 35B is a drawing hole of the through hole 34B formed in the memory link 34. Positioning the lower half of the through-hole 34B in the vehicle width direction, the holding operation pins 36B of the release holding member 36, which will be described later, In the vehicle width direction over the overlapping hole shape.

  The holding operation hole 35B of the release link 35 described above is operated by the memory lever 6 being operated as shown in FIGS. 19 and 20, and the memory link 34 is pushed downward alone by leaving the release link 35 as shown in FIG. When the memory link 34 is rotated to deflect the lock spring 13 beyond the lock release position shown in FIG. The hole 34Ba formed in the hole area of FIG. By the above state, as shown in FIG. 22, the holding operation pin 36B of the release holding member 36, which will be described later, passing over both holes (the holding operation hole 35B and the through hole 34B) is caused by the spring urging force. It goes into the drawing hole 34Ba. Accordingly, the rotation movement of the memory link 34 in the counterclockwise direction with respect to the release link 35 is restricted via the holding operation pin 36B of the release holding member 36, and the memory link 34 The state is maintained in the posture position where the release operation has been performed.

  As shown in FIGS. 8 and 9, the lower edge portion of the intermediate region extending rearward from the front region passed through the rod 32 of the release link 35 described above has an outer side (right side) in the vehicle width direction. A pressure-receiving piece 35D that is bent and protrudes is formed. As shown in FIGS. 8 and 12, when the release arm 33 is pushed down by the operation of the loop handle 5, the pressure receiving piece 35D is pressed down from above by pressing the release arm 33 from above. It functions as a receiving part pushed to the side. When the memory link 34 is operated by operating the memory lever 6 as shown in FIGS. 19 and 20, the release link 35 is not operated at all as shown in FIGS. ing.

  As shown in FIGS. 8 and 9, the release holding member 36 is formed of a single sheet material such as steel facing the vehicle width direction. The release holding member 36 is rotated by an axis pin 36A that directs the axis in the vehicle width direction to the inner surface side (right surface side) of the rear area of the release link 35 described above, specifically, to the inner surface position below the holding operation hole 35B. It is provided as a pin-connected state as possible. A holding operation pin 36B is attached to the release holding member 36 at a position above the shaft pin 36A so as to protrude inward (left side) in the vehicle width direction. Further, a pressure receiving piece 36 </ b> C that is bent and protruded outward (right side) in the vehicle width direction is formed at a rear lower edge portion of the release holding member 36.

  As shown in FIG. 10, the holding operation pin 36B is provided with a holding operation hole 35B formed in the release link 35 and a through hole formed in the memory link 34 with the assembling of the release holding member 36 to the release link 35. It is designed to be assembled in a state of being passed in the vehicle width direction across the hole 34B. As a result of the assembling, the release holding member 36 is formed such that the above-described holding operation hole 35B formed in the release link 35 and the through hole 34B formed in the memory link 34 are overlapped in the vehicle width direction. Within the range of the hole shape, it is in a state where it can be rotated with respect to the release link 35.

  As shown in FIG. 8, the pressure-receiving piece 36 </ b> C extends from the release holding member 36 to the outside (right side) in the vehicle width direction, and is provided in a state where its arm shape is located directly below the release arm 33 described above. I have. As shown in FIGS. 12 and 37, when the release arm 33 is pushed downward by the operation of the loop handle 5 as shown in FIGS. It functions as a receiving part pushed to the side.

  As shown in FIG. 10, the release holding member 36 is always centered on the shaft pin 36 </ b> A with respect to the release link 35 by the urging force of a spring (not shown) hooked between the release link 35 and the release link 35. Is applied with a force that rotates clockwise in the drawing. With the above configuration, when the release link 35 and the memory link 34 are held at the initial position, the release holding member 36 presses the holding operation pin 36B against the rear side surface of the through hole 34B of the memory link 34. It is in a state of being held at the set rotation position.

  The memory link 34 is pushed downward by the operation of the memory lever 6 as described above with reference to FIGS. 19 and 20, and the release holding member 36 is moved to the upper half side of the through hole 34B as shown in FIG. 22 and the holding operation hole 35B of the release link 35 are overlapped with each other in the vehicle width direction, so that the holding operation pin 36B is pressed by the spring urging force as shown in FIG. It is designed to enter the drawing hole 34Ba. Due to the entry, the rotational movement of the memory link 34 with respect to the release link 35 in the counterclockwise direction in the drawing is restricted via the holding operation pin 36B, and the posture position where the memory link 34 is released with respect to the release link 35 Is held.

  As shown in FIG. 37, the release arm 33 is pushed down by operating the loop handle 5 from the state where the memory link 34 is held at the position where the release operation is performed, as shown in FIG. The holding arm 36B is pushed around the shaft pin 36A in the counterclockwise direction in the figure by the release arm 33 so that the holding operation pin 36B is disengaged from the drawing hole 34Ba. By the above operation, the holding state of the memory link 34 at the release operation position via the release holding member 36 is released, and as shown in FIG. The operating position is once returned to a position where it is pressed from the side.

  By this operation, the memory link 34 releases the state in which the lock spring 13 is pressed and bent downward as shown in FIG. 39, and returns to the state in which the slide rail 10 is slid-locked by the restoring deformation of the lock spring 13. It has become. However, as shown in FIG. 40, in the memory link 34 whose operation position has been returned to the upper side, the release link 35 described above is continuously pushed downward by the release arm 33 by the operation of the loop handle 5 described above. After being in contact with the eaves piece 35C, the lock spring 13 is pushed down again together with the release link 35 as shown in FIG. A slide lock release operation is performed.

  As shown in FIGS. 7 and 9, the L-shaped link 37 is formed of a single sheet of steel or the like cut into a substantially L-shape facing the vehicle width direction. The L-shaped link 37 is provided such that the L-shaped bent portion is rotatably pin-connected to the inner surface of the intermediate region of the base bracket 31 by a shaft pin 37A that turns the axis in the vehicle width direction. . As shown in FIG. 11, the aforementioned L-shaped link 37 is always centered on the shaft pin 37A with respect to the base bracket 31 by the urging force of a spring (not shown) hooked between the L bracket 37 and the base bracket 31 described above. Is applied with a force to rotate in the counterclockwise direction in the drawing. With the above configuration, in the free state, the L-shaped link 37 moves by the arm portion extending upward from the L-shaped portion being pressed against the locking piece 31A formed on the upper edge of the base bracket 31 from the rear side. The state is maintained in a regulated state.

  The above-mentioned memory lever 6 is connected to the distal end of the arm portion extending above the L-shaped link 37 via a double-structured cable 37B. With the above configuration, the L-shaped link 37 is rotated clockwise in the figure via the cable 37B by the operation of raising the memory lever 6, as shown in FIGS. By the above rotation operation, the L-shaped link 37 is connected to a transmission link 38 to be described later by an operation cam 38D which is connected to a transmission link 38 by a kick pin 37C which is attached to a tip end of an arm portion extending rearward and protrudes in the vehicle width direction. Is pushed down, and the memory link 34 gear-coupled to the transmission link 38 is pushed down. With the above configuration, the memory link 34 is operated so as to be pushed downward by the operation of the memory lever 6.

  As shown in FIGS. 7 and 9, the transmission link 38 is formed of a single plate material such as steel, which is cut into a substantially fan shape facing the surface in the vehicle width direction. The transmission link 38 meshes a gear 38B formed on the front outer peripheral surface of the fan shape with a gear 34C formed on the rear outer peripheral surface of the memory link 34 at the rear position of the memory link 34 described above. In this state, the rear end of the base bracket 31 is rotatably connected to the inner surface of the rear region of the base bracket 31 by a shaft pin 38A whose axis is oriented in the vehicle width direction. An operation cam 38D is provided at an outer surface position (a left surface position) of a front region of the transmission link 38 described above in a state where the operation cam 38D is rotatably connected to a pin 38Da that directs an axis in the vehicle width direction. .

  The operation cam 38D is formed of a substantially flat member whose surface faces in the vehicle width direction. The operation cam 38D is normally moved counterclockwise with respect to the transmission link 38 as shown in FIG. 11 by the urging force of a spring (not shown) attached to the transmission link 38 as described above. It is assumed that a rotating force is applied. With the above configuration, in the free state, the operation cam 38D rotates in the same direction at a position where it comes into contact with a locking piece 38C formed on the lower edge of the transmission link 38 and extending in the vehicle width direction from the front side. The state is held as a regulated state.

  As shown in FIGS. 19 and 20, the operation cam 38D is rotated by pushing the memory lever 6 upward to push the L-shaped link 37 clockwise around the shaft pin 37A in the illustrated direction. The kick pin 37C of the L-shaped link 37 is pressed from above. Due to the pressing, the operation cam 38D receives a force to rotate the transmission link 38 in the counterclockwise direction in the figure around the shaft pin 38Da, but the movement in the same direction is restricted. The force received from the kick pin 37C of the character link 37 is integrated with the transmission link 38 and pushed downward about the shaft pin 38A. Then, due to the rotation, the rotational power of the transmission link 38 is transmitted to the memory link 34, and the memory link 34 is also pushed downward, whereby the lock spring 13 is released.

  Even after the operation cam 38D is deflected to the position where the lock spring 13 releases the slide lock by the rotation of the memory link 34 as shown in FIG. 20, further operation of the memory lever 6 as shown in FIG. Is pushed downward by the L-shaped link 37 as the travel progresses. At this time, when the operation link 38 is excessively pushed and turned, the memory link 34 is excessively pushed down and the internal operation arm 39 is excessively pressed against the lock spring 13. The arc surface 39B1 formed on the surface allows the internal operation arm 39 to escape so as not to deflect the lock spring 13 downward more than a certain amount. However, in order to prevent the arc surface 39B1 from slipping out of the lock spring 13 by sliding over the lock spring 13 on the outer peripheral surface of the internal operation arm 39, a lock spring is provided at the end position of the arc surface 39B1. A stopper 39 </ b> B <b> 2, which is hung and hits 13, is formed to protrude. The stopper 39B2 regulates the movement of the internal operation arm 39 to escape so as not to deflect the lock spring 13 downward more than a certain amount.

  Therefore, at the stage before the stopper 39B2 of the internal operation arm 39 hits the lock spring 13 and is locked, the operation cam 38D is disengaged from the contact state with the kick pin 37C of the L-shaped link 37, As shown in FIG. 25, even if the rotation of the L-shaped link 37 progresses, the movement of the L-shaped link 37 is not released and excessive power is not transmitted to the memory lever 6 without being pushed further downward. So that you can do it. As described above, when the operation cam 38D is released from the state of contact with the kick pin 37C of the L-shaped link 37, the memory link 34 is rotated upward by the spring urging force. . However, in the above state, as described above with reference to FIG. 22, the holding operation pin 36B of the release holding member 36 is in a state of being inserted into the drawing hole 34Ba of the memory link 34 by the spring biasing force. As shown in FIG. 28, the memory link 34 is held at the position where the release link 35 has been released.

  Then, as shown in FIG. 25, as the operation of the memory lever 6 proceeds, the vertical position relationship between the operation cam 38D and the kick pin 37C of the L-shaped link 37 is reversed, and the memory lever 6 When the operation is returned, the operation cam 38D is pressed from below by the kick pin 37C of the L-shaped link 37, as shown in FIG. However, at this time, the operation cam 38D rotates in the illustrated clockwise direction about the shaft pin 38Da with respect to the transmission link 38, so that the rotation of the L-shaped link 37 in the illustrated counterclockwise direction is released. Therefore, when the operation of the memory lever 6 is returned, the vertical positional relationship between the operation cam 38D and the kick pin 37C of the L-shaped link 37 becomes as shown in FIG. It will be returned to the original vertical position relationship.

  As shown in FIGS. 6 and 7, the internal operation arm 39 has a shape in which one sheet material such as steel has a pair of left and right substantially fan-shaped pressing pieces 39 </ b> B facing the surface in the vehicle width direction. It is formed so as to be bent. The inner operation arm 39 is provided in a state where its rear end is rotatably connected to the top plate 12A of the upper rail 12 described above with reference to FIG. 6 by a shaft pin 39A whose axis is oriented in the vehicle width direction. . As shown in FIG. 11, the internal operation arm 39 is always shown around the shaft pin 39A by the urging force of a spring (not shown) attached between the inner operation arm 39 and the top plate 12A of the upper rail 12. It is assumed that a clockwise rotating force is applied. According to the above configuration, in the free state, the internal operation arm 39 is held in a state where the rotational movement in the same direction is restricted at a position where the inner operation arm 39 is brought into contact with the top plate 12A (see FIG. 6) of the upper rail 12 from below. State.

  As shown in FIG. 11, in the free state, the left and right pressing pieces 39B of the internal operation arm 39 are located immediately above one of the left and right lock portions 13C of the lock spring 13. The internal operation arm 39 is pushed downward by the operation of the loop handle 5 described above with reference to FIG. 12 and the operation of the memory lever 6 described above with reference to FIG. 19, as shown in FIGS. Thus, the release piece 34A of the memory link 34 is pressed against the top plate portion from above, and is pushed counterclockwise around the shaft pin 39A. With the above configuration, the inner operation arm 39 pushes the left and right lock portions 13C of the respective lock springs 13 downward by the lower surfaces of the left and right pressing pieces 39B to be disengaged from the lock groove 11C of the lower rail 11 (see FIG. 6). It has become. Further, the internal operation arm 39 is returned to the state shown in FIG. 11 by the spring biasing force when the operation state in which the memory link 34 is pressed down is returned and the release piece 34A is released upward, and the lock spring The lock portions 13C on the left and right sides of the lower rail 13 are restored to a state where they are inserted into the lock grooves 11C of the lower rail 11 (see FIG. 6).

  As shown in FIG. 20, the internal operation arm 39 described above is pushed down by the memory link 34 by the operation of the memory lever 6 described above, and locks the right and left lock portions 13C of the lock spring 13 with the lock groove 11C of the lower rail 11 (see FIG. 6). When the memory link 6 receives a force further depressed by the further progress of the operation of the memory lever 6 even after it is released from the state, as shown in FIG. Is formed on the lock portions 13C on the left and right sides of the lock spring 13. The arc surface 39B1 has a shape curved in an arc shape drawn around a shaft pin 39A which is a rotation center of the internal operation arm 39. Therefore, even if the circular surface 39B1 rides on the left and right lock portions 13C of the lock spring 13, even if the rotation of the internal operation arm 39 is pushed down from that position, the power from the internal operation arm 39 to the lock spring 13 is increased. The transmission is released, and the lock portions 13C on the left and right sides of the lock spring 13 are no longer pushed downward and deflected. Therefore, a problem such as that the lock spring 13 bottoms on the bottom surface of the upper side fin portion 12B (see FIG. 6) of the upper rail 12 occurs, or the memory lever 6 which performs the operation of pushing down the memory link 34 as shown in FIG. There is no situation where an excessive operation load is applied.

  On the outer peripheral surface of each pressing piece 39B of the internal operation arm 39, the above-described arc surface 39B1 slides downward on each lock portion 13C of the lock spring 13 and comes off from the lock spring 13 downward. In order to prevent this, a stopper 39B2 which functions so as to abut on and lock each lock portion 13C of the lock spring 13 is formed at the end position (upper end position) of the arc surface 39B1 so as to protrude.

《Overall operation》
In summary, the memory mechanism 20 and the operating mechanism 30 described above are moved as follows by the operation of raising the loop handle 5 and the operation of raising the memory lever 6 described above with reference to FIGS. It has become. That is, first, when the seat 1 is in the initial state in which the operation of the loop handle 5 and the memory lever 6 described above is not performed, as shown in FIG. 13C is locked by inserting it into each lock groove 11C of the lower rail 11 (see FIG. 6). As shown in FIG. 10, the memory mechanism 20 is configured such that the hook 21Ba of the memory body 21 is locked by entering into the memory groove 21Ab of the memory plate 21A, and the holding release operation link 22A of the trigger 22 is connected to the memory slider 21B. And is in a state of forming an adjacent positional relationship in a standing posture by being pressed from the rear side.

  First, when the lifting operation of the loop handle 5 is performed from the initial state, as shown in FIG. 12, the release link 35 is pivoted around the rod 32 by the release arm 33 integrally connected to the loop handle 5. It is operated to rotate clockwise in the figure. As a result, the memory link 34 is also rotated clockwise in FIG. 13 around the rod 32 in such a manner as to be pressed from above by the release link 35, and the lock spring 13 is moved through the internal operation arm 39 as shown in FIG. The slide is unlocked by being depressed downward. Also, as shown in FIG. 12, while the engagement / disengagement piece 35A of the release link 35 enters into the engagement hole 21Bb1 of the leaf spring 21Bb of the memory slider 21B, the leaf spring 21Bb is pushed downward to bend and the hook 21Ba is bent. 21A is removed from the memory groove 21Ab. By the above operation, the memory slider 21B is engaged with the release link 35 so as to be able to move integrally in the sliding direction.

  Therefore, as shown in FIG. 4, the seat 1 is slid in the front-rear direction while the loop handle 5 is being pulled up, so that the lock spring 13 is pushed down by the internal operation arm 39 as shown in FIG. The seat position can be changed while pulling the memory slider 21B together. Further, in this case, while the loop handle 5 is being pulled up, the seat position is retracted to the boarding / alighting support position (the imaginary line position in FIG. 1) near the rear mast as shown in FIG. Even if the holding release operation link 22A is pressed from the front side against the stopper link 16A of the stopper bracket 16 waiting at the getting on / off support position, the holding release operation link 22A is pushed back by the stopper link 16A as shown in FIG. The slide pin 22Ac on the upper end side slides in the escape area 22Bb2 of the long hole 22Bb of the power transmission plate 22B to escape the contact with the stopper link 16A. With the above configuration, as shown in FIG. 17, the holding / releasing operation link 22A can be slipped behind the stopper link 16A and the seat position can be slid to the rear most position.

  Further, as shown in FIG. 18, when the seat position is returned from the rear most position to the front side, the stopper link 16A is pushed forward by the holding release operation link 22A to release the contact with the holding release operation link 22A. Thus, the seat position can be returned to a position on the front side of the getting on / off support position (the imaginary line position in FIG. 1) near the rear mast. Then, by returning the operation of the loop handle 5 after the movement, the operation mechanism 30 and the memory mechanism 20 are returned to the initial positions shown in FIGS. 10 to 11, and the seat position is locked at the changed position. be able to. With the above operation, the adjustment operation of the seat position using the loop handle 5 is completed.

  Next, the operation when the memory lever 6 is operated from the initial state will be described. That is, as shown in FIGS. 19 and 20, when the memory lever 6 is operated, the L-shaped link 37 is rotated via the cable 37B, and the transmission link 38 pushed and kicked by the L-shaped link 37 is moved. The memory link 34 is rotated around the rod 32 in the clockwise direction in FIG. As a result, as shown in FIG. 20, the internal operation arm 39 is pushed down by the memory link 34, and the lock spring 13 is pushed down and bent, thereby releasing the locked state of the slide.

  At the same time, as shown in FIGS. 21 to 23, the rotation of the memory link 34 causes the holding operation pin 36B of the release holding member 36 to enter the drawing hole 34Ba of the memory link 34. Then, as shown in FIGS. 24 to 26, even if the memory lever 6 is operated to the full stroke position, the operation cam 38D is disengaged from the contact with the L-shaped link 37 or the internal operation arm 39 is locked by the lock spring. An excessive operation movement amount of the memory lever 6 is escaped by releasing the hit by the arc surface 39B1 so as not to push the 13 excessively. Then, even when the operation of the memory lever 6 is returned as shown in FIG. 27, the memory link 34 is held at the position where the release operation has been performed by being hooked on the holding operation pin 36B as shown in FIG. State.

  Therefore, as shown in FIG. 1, after the operation of the memory lever 6, the seat 1 is slid rearward from that position, whereby the lock spring 13 is pushed down by the internal operation arm 39 as shown in FIG. 29. As shown in FIG. 30, the seat position can be moved to the rear side while leaving the memory slider 21B. Due to the above movement, the holding release operation link 22A of the trigger 22 is pulled rearward from the memory slider 21B and rotates backward and tilts, and the operation cam 22C connected to the power transmission plate 22B of the trigger 22 is released as shown in FIG. The holding member 36 is in a state in which the kicked piece 36D has slipped downward.

  Therefore, as shown in FIG. 32, when the seat position is retracted from the above state toward the getting on / off support position (the imaginary line position in FIG. 1) near the rear mast, the holding release operation link 22A of the trigger 22 is moved to the getting on / off support position. The waiting stopper bracket 16 is pressed against the stopper link 16A from the front side. Then, when the seat position is moved backward as shown in FIGS. 33 to 34, the holding release operation link 22A is turned back forward by the stopper link 16A along with the movement, and the power transmission plate is moved. The operation cam 22C connected to the release holding member 36 pushes the kicking piece 36D of the release holding member 36 from below, and the holding operation pin 36B of the release holding member 36 is removed from the drawing hole 34Ba of the memory link 34. As a result, the holding state of the memory link 34 at the release operation position is released, and the memory link 34 returns to the upward rotation as shown in FIG. 35, and the lock spring 13 returns to each of the lower rails 11 as shown in FIG. The slide enters the lock groove 11C (see FIG. 6) and the slide is locked. By the above operation, the seat position is locked at the getting on / off support position (the imaginary line position in FIG. 1) near the rear mast.

  With the above-described lock, the seat position can be temporarily locked at the boarding / alighting support position (the virtual line position in FIG. 1) in the vicinity of the rear mast, so that a wide boarding / alighting space is secured in front of the seat 1. Will be retained. The rotation posture of the trigger 22 when the seat position is temporarily locked at the getting on / off support position (the imaginary line position in FIG. 1) near the rear mast is the same as in FIG. The operation cam 22C connected to the rotation holding member 36 is in a rotational posture that exceeds the kicked piece 36D of the release holding member 36 upward.

  Next, a description will be given of the movement when the memory lever 6 is operated again from the state where the seat position is locked at the getting on / off support position (the imaginary line position in FIG. 1) near the rear mast. In this case, the memory link 34 is pushed down again and the lock spring 13 is moved downward similarly to the case where the memory lever 6 is operated in the initial state shown in FIGS. 28, the slide lock is released, and as shown in FIG. 28, after the memory lever 6 is operated, the memory link 34 is again held at the position where the release operation has been performed by being hooked on the holding operation pin 36B. State. Therefore, as shown by the solid line state in FIG. 2, after the operation of the memory lever 6, the seat 1 is slid forward from that position, and the seat position before the change shown by the virtual line state in FIG. That is, it is possible to move the memory slider 21B left at the storage position before the change described above with reference to FIG. 30 to the front side to the position where the holding release operation link 22A of the trigger 22 is pressed from the rear side.

  When the holding release operation link 22A of the trigger 22 is pressed against the memory slider 21B left at the above-mentioned storage position from the rear side, the forward movement of the seat position therefrom as in the case shown in FIGS. As a result, the holding release operation link 22A is turned by the memory slider 21B so as to be pinched forward, and the operation cam 22C connected to the power transmission plate 22B pushes the kicking piece 36D of the release holding member 36 from below. Then, the holding operation pin 36B of the release holding member 36 is removed from the drawing hole 34Ba of the memory link 34. Thereby, the holding state of the memory link 34 at the release operation position is released, and the memory link 34 returns to the upward rotation in the same manner as the state shown in FIG. 35, and becomes the same as the state shown in FIG. The lock spring 13 enters the lock grooves 11C (see FIG. 6) of the lower rail 11 again, and the slide is locked. By the above operation, the seat position is returned to the storage position before the change (the virtual line position in FIG. 2), and the seat position is locked.

  Next, from the state where the operation of the memory lever 6 shown in FIGS. 19 and 20 described above is performed and the memory link 34 is held at the position where the release operation is performed as shown in FIG. 28 (memory state), FIG. The operation when the loop handle 5 is operated as shown in FIG. In this case, as shown in FIG. 37, since the pressure receiving piece 36C of the release holding member 36 that holds the memory link 34 at the position where the release operation is performed is higher than the pressure receiving piece 35D of the release link 35, Then, the pressure receiving piece 36C of the release holding member 36 hits the release arm 33 and is pushed downward. Thereby, the holding operation pin 36B of the release holding member 36 is removed from the drawing hole 34Ba of the memory link 34, and the holding state of the memory link 34 at the release operation position is released.

  Then, as shown in FIG. 38, the memory link 34 is returned to a position where the memory link 34 is pressed against the eaves 35C of the release link 35 from below by the spring urging force. As shown in FIG. 10 (see FIG. 6) is returned to the slide locked state. However, as shown in FIG. 40, as the operation of the loop handle 5 described above progresses, the release link 35 described above is pushed downward, so that the memory link 34 is pushed downward together with the release link 35 again. Then, as shown in FIG. 41, the lock spring 13 is once again depressed and bent downward, and the slide lock is released.

  As shown in FIG. 42, the operation of the loop handle 5 in the memory state after the operation of the memory lever 6 shown in FIG. 3 is performed by the memory slider 21B in which the holding release operation link 22A of the trigger 22 is left at the storage position described above. When the engagement is performed at a position away from the rear side, the disengagement piece 35A of the release link 35 is pushed down at a position displaced rearward from a position where it can enter the engagement hole 21Bb1 formed in the leaf spring 21Bb of the memory slider 21B. Therefore, an operation of merely pushing down to a height position corresponding to a position that can enter the engagement hole 21Bb1 without entering the engagement hole 21Bb1 is performed. The position where the engagement piece 35A is pushed down is a position where the leaf spring 21Bb enters a height region obliquely bridged.

  However, by moving the seat position forward with the loop handle 5 pulled up from that position, as shown in FIG. 43, the above-described engagement / disengagement piece 35A of the release link 35 rides on the leaf spring 21Bb. As shown in FIG. 44, the plate spring 21Bb passes over the leaf spring 21Bb which rises obliquely in a forwardly rising shape, and slides to the position where the engaging hole 21Bb1 is present while pushing and bending the leaf spring 21Bb downward, and as shown in FIG. As described above, it enters into the engagement hole 21Bb1. The above movement causes the leaf spring 21Bb to be depressed and bent downward, and the hook 21Ba is released from the memory groove 21Ab of the memory plate 21A. Thereby, the memory slider 21B can move integrally with the release link 35 in the sliding direction, which is the same state as when the loop handle 5 is operated in the initial state shown in FIG. Therefore, thereafter, as in the case described above, the seat position can be adjusted while pulling the memory slider 21B, or the loop handle 5 can be returned and locked at that position.

  By the way, by operating the memory lever 6 described above with reference to FIGS. 19 and 20, the operation mechanism 30 is switched to the memory state as shown in FIG. 30, and the holding release operation link 22A of the trigger 22 is left at the storage position. When the seat position is suddenly moved forward due to a frontal collision of the vehicle in a state of being separated from the slider 21B to the rear side, the holding release operation is performed as shown by a virtual line state in FIG. Even if the link 22A is pressed against the memory slider 21B from the rear side to be in a standing posture, the holding release operation link 22A is pushed and rotated by the operation cam 22C connected to the power transmission plate 22B at that position. 36, the lock spring 13 returns to the locked position as shown in FIG. Try operation will at a later point in time to, seat position is sometimes overcome the operation about to be moved faster in the forward direction. In such a case, as shown by the imaginary line state in FIG. 46, a configuration in which the holding release operation link 22A is stepped on the memory slider 21B at the above-described standing posture position to receive the force applied to the front side thereof. In this case, an excessive load is applied to each mechanism including the holding release operation link 22A, and the above load cannot be properly received.

  However, even when the holding release operation link 22A is pressed against the memory slider 21B from the rear side at an excessively rapid speed as described above, even if the link is in the upright posture in which the slide lock should be originally performed, the slide lock is not performed. 46, the slide pins 22Ac are not stepped on the memory slider 21B in the upright posture, but are moved from the power transmission plate 22B by the slide pin 22Ac to the escape area of the elongated hole 22Bb, as shown by the solid line in FIG. By sliding inside 22Bb2, a strong contact with the memory slider 21B can be released. With the above-described configuration, even if the lock spring 13 is returned to the lock position beyond the lock position where the lock should be returned as shown in FIG. The time delay can be absorbed without overloading other mechanisms. Even when the lock spring 13 returns to the locked state at such a rapid speed as described above, the resilient force of the lock spring 13 causes the tooth to jump forward by one pitch from the locked position at which the lock should be returned to the original position. The lock can be restored.

  Then, when the lock spring 13 returns to the lock position at the position where the tooth jumps forward by one pitch, as shown by a solid line in FIG. 46, the engagement / disengagement piece 35A of the release link 35 becomes the leaf spring 21Bb of the memory slider 21B. Is located on the front side with respect to the rear engagement hole 21Bb1 formed at the bottom. However, even when the tooth jump occurs, the leaf spring 21Bb has another engagement hole at a position where the engagement piece 35A can be received when the engagement piece 35A of the release link 35 is pressed down at that position. 21Bb1 is formed. Therefore, even after the lock is restored at the tooth jump position, the release link 35 is integrally moved with the memory slider 21B in the sliding direction by operating the loop handle 5 (see FIG. 12) therefrom. It can be engaged in the state in which it is made to be.

《Summary》
In summary, the slide rail device M of the present embodiment has the following configuration. That is, the seat position includes a slide rail (slide rail 10) whose seat position can be adjusted by a release operation of a lock mechanism (lock spring 13), and a memory member (memory slider 21B) for storing a position before the seat position is changed. And a memory mechanism (memory mechanism 20) that allows the storage position to be restored to the storage position before the change. This vehicle slide rail device (slide rail device M) releases the lock mechanism (lock spring 13) and releases the memory member (memory slider 21B) from the position storage state to release the memory member (memory slider 21B) in the sliding direction.
