<< ● About the outline configuration of the slide rail device M >>
First, the configuration of the seat 1 to which the slide rail device M (slide rail device for vehicles) of the first embodiment is applied will be described with reference to FIGS. 1 to 41. As shown in FIG. 1, the seat 1 of this embodiment is configured as a driver's seat of a right-hand drive vehicle. 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 described above is connected to the floor F of the vehicle via a pair of left and right slide rails 10 constituting the slide rail device M described above. Further, the seat back 2 is connected to the rear end portion of the seat cushion 3 described above with a pair of left and right reclinings (not shown) interposed therebetween. Further, the headrest 4 is provided so as to be mounted on the upper part of the seat back 2.

In the following description, when each direction such as front-back, up-down, left-right, etc. is shown, it means each direction shown in each figure. Further, the term "seat width direction" refers to the width direction (left-right direction) of the seat 1, and the term "vehicle width direction" refers to the width direction (left-right direction) of the vehicle. That is, 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 (inner) (not shown), and the term "outside in the vehicle width direction" refers to the right side of the seat 1. That is, it refers to the side (outer) with the entrance / exit door (not shown).

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

Further, as shown in FIG. 1, each of the slide rails 10 described above is also subjected to an operation in which the boarding / alighting lever 6 provided on the outer side (right side) of the seat cushion 3 in the vehicle width direction is pulled up by the user. The slide-locked state of is released all at once (circled number 1). Then, each slide rail 10 pulls down the seat position to the rear side while maintaining the operation state of the above-mentioned boarding / alighting lever 6, and by the action of the operation mechanism 30 provided in the slide rail device M described later. The movement is locked when the seat back 2 is lowered to the boarding / alighting support position near the rear most where the position in the front-rear direction overlaps with the B-pillar BP of the vehicle (circled number 2).

Specifically, each of the slide rails 10 described above is slid-locked at that position even if the operating state of the boarding / alighting lever 6 described above is maintained by lowering the seat position to the boarding / alighting support position near the rear most described above. It is designed to be switched to the state where it is. Therefore, the seat position is pulled down to the rear side while the boarding / alighting lever 6 is operated, and the movement is stopped, so that the seat position reaches the boarding / alighting support position near the rear most and a wide boarding / alighting space is created. It is possible to make the user recognize that the state has been switched to the secured state.

Further, each of the slide rails 10 described above is operated again by the user so that the boarding / alighting lever 6 is pulled up from the state where the seat position is lowered to the boarding / alighting support position near the rear most as described above. The slide-locked state is released all at once (circled number 3). Then, each slide rail 10 moves the seat position to the front side while maintaining the above-mentioned operating state of the boarding / alighting lever 6, and the seat position is lowered to the rear side by the action of the above-mentioned operation mechanism 30. When the initial position before the slide is reached, that is, the position when the boarding / alighting lever 6 is operated and lowered to the rear side, those slides are returned to the locked state (circled number 4). ..

That is, when the boarding / alighting lever 6 is operated to change the seat position, the slide rail device M can store the position of the seat position when the boarding / alighting lever 6 is operated. By returning to the original position after changing the seat position, when the seat position reaches the above-mentioned memorized position, the slide is switched to the locked state and the seat position is returned to the memorized position before the change. It can be easily restored. Therefore, after a person sits on the seat 1 at the boarding / alighting support position near the rear most described above, the person operates the boarding / alighting lever 6 again to move the seat position toward the front side while maintaining the operated state. As a result, the seat position can be returned to the storage position before the change at once, and the seat position can be returned to the locked state at that position.

In each of the slide rails 10 described above, as shown in FIG. 3, the operating state of the boarding / alighting lever 6 described above is solved at an intermediate position between the storage position before the change and the boarding / alighting support position near the rear most in FIG. When it is broken, it can be switched to the slide-locked state at any position where it is unlocked. Then, each slide rail 10 is again operated with the boarding / alighting lever 6 at the slide-locked arbitrary position, so that the seat position is again set to the storage position before the change described in FIG. 1 and the boarding / alighting support near the rear most. It can be switched to a state where it can be freely adjusted with and from the position. Then, each slide rail 10 is slid-locked at the same position by moving the seat position to the storage position before the change described in FIG. 1 while maintaining the operation state of the boarding / alighting lever 6 described above. It is supposed to be returned to.

<< ▲ About the concrete configuration of the slide rail 10 >>
Hereinafter, specific configurations of each of the pair of left and right slide rails 10, the memory mechanism 20, and the operation mechanism 30 that constitute 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. 4 to 5. That is, each slide rail 10 includes a lower rail 11 mounted on the floor F and an upper rail 12 mounted on the lower part of the seat cushion 3 while being assembled so as to be slidable in the front-rear direction with respect to the lower rail 11. It is configured to have a lock spring 13 for locking the slide between the rails 11 and 12. Since the basic structure of each slide rail 10 is substantially the same on the left and right sides of each other, the detailed configurations of the slide rails 10 are slides arranged inside (left side) in the vehicle width direction shown in FIG. The description will be made on behalf of the configuration of the rail 10. Here, the lock spring 13 described above corresponds to the "lock mechanism" of the present invention.

As shown in FIG. 5, the above-mentioned lower rail 11 is formed by bending a plate material such as a steel plate extending in a long shape in the front-rear direction of a vehicle into a substantially U-shape in the short direction. Each of the front and rear ends of the lower rail 11 described above is integrally fastened and fixed on the floor F by a fastening structure such as a bolt (not shown). The lower rail 11 described above is formed in a rail shape in which the cross-sectional shape thereof is substantially uniform in the front-rear direction.

Specifically, the above-mentioned lower rail 11 has a bottom surface portion 11A set on the floor F with its surface facing upward, and a bottom surface portion 11A extending upward from the left and right side edges of the bottom surface portion 11A toward the inward side of each other. It is formed in a cross-sectional shape having a pair of left and right lower side fin portions 11B having a shape that is bent back in an inverted U shape and extends. The lower rail 11 described above is a bolt (not shown) in which the front and rear end portions of the bottom surface portion 11A described above are set in a state where they are in surface contact with each other from above on the floor F, and are inserted into each portion from above. It is in a state of being integrally fastened on the floor F by a fastening structure such as.

On the left and right lower side fin portions 11B of the lower rail 11 described above, the corresponding lock portions 13C of the lock spring 13 described later are respectively placed from the lower side at each edge portion of the tip bent back in an inverted U shape. A lock groove 11C is formed that can be inserted and engaged. A plurality of these lock grooves 11C are arranged at equal intervals in the front-rear direction in a shape that opens downward along each edge portion of the tip that is folded back and hangs down inside each lower side fin portion 11B. It is said to be in a formed state. The lock grooves 11C formed in the lower fin portion 11B are formed side by side at positions symmetrical with each other.

Further, on the left and right lower side fin portions 11B of the lower rail 11 described above, slides of the upper rail 12 in the front-rear direction are provided at a portion near the front end portion and a portion near the rear end portion of each side surface portion rising from the bottom surface portion 11A. The locking claws 11D and 11E are formed so as to be cut up diagonally inward. These locking claws 11D and 11E are cut up after the upper rail 12 is inserted into the lower rail 11 described above, and the sliding of the upper rail 12 in the front-rear direction is made with the front locking claw 12D formed on the upper rail 12. It is regulated by the contact with the lock claw 12E on the rear side and the contact with the locking claw 12E on the rear side.

The front end side locking claws 11D formed on the lower rail 11 described above are formed at positions separated from the front end side lock grooves 11C formed on the lower rail 11. Further, each of the locking claws 11E on the rear end side formed on the lower rail 11 described above is formed at a position separated from each lock groove 11C on the rear end side formed on the lower rail 11. Due to such an arrangement, the lower rail 11 locks the slide of the upper rail 12 described above in the lock region A1 (see FIG. 34) in which the lock grooves 11C described above are arranged in the front-rear direction, but the slide of the upper rail 12 is locked. The slide itself can allow each overstroke region A2 (see FIG. 34) beyond the lock region A1 in the front-rear direction.

Similar to the lower rail 11 described above, the upper rail 12 is formed by bending a plate material such as steel extending in a long shape in the front-rear direction of the vehicle into a substantially Ω-shaped shape in the short direction. The above-mentioned upper rail 12 is inserted into the lower rail 11 from the opening end on either side of the above-mentioned lower rail 11 in the longitudinal direction, so that the upper rail 12 can be assembled so as to be slidable in the longitudinal direction with respect to the lower rail 11. ing. Specifically, the upper rail 12 has a top plate portion 12A attached with its cross-sectional shape facing upward toward the lower portion of the seat cushion 3 described above, and the left and right side edges of the top plate portion 12A. It is formed in a cross-sectional shape having a pair of left and right upper side fin portions 12B having a shape extending downward from the portion and being bent back in a U shape toward the outer side opposite to each other. The top plate portion 12A of the upper rail 12 described above is formed with a through hole 12Aa for passing the components of the memory mechanism 20 and the operation mechanism 30, which will be described later, in the height direction.

In the above-mentioned upper rail 12, each edge portion of the left and right upper side fin portions 12B bent back in a U shape with respect to the above-mentioned lower rail 11 is an inverted U of the left and right lower side fin portions 11B of the lower rail 11. It is inserted and assembled in the longitudinal direction so as to engage with each part bent back in a shape. By being assembled in this way, the upper rail 12 is in the height direction with respect to the lower rail 11 due to the engagement of the left and right upper side fin portions 12B and the lower side fin portion 11B with respect to the lower rail 11. It is said that it is assembled in a state where it is prevented from coming off in the seat width direction. Specifically, the above-mentioned upper rail 12 is in the height direction and the seat width direction with respect to the lower rail 11 via a resin shoe and a steel ball (rolling body) (not shown) assembled between the above-mentioned upper rail 12 and the above-mentioned lower rail 11. It is said that they are assembled so that they can slide smoothly in the front-back direction while suppressing backlash.

The left and right lock portions 13C of the lock spring 13, which will be described later, are placed from the inside to the outside at the central portion in the front-rear direction of each side surface portion hanging from the top plate portion 12A of the left and right upper side fin portions 12B of the upper rail 12 described above. A through groove 12C is formed to pass through. Further, in each fin portion of each upper side fin portion 12B that has been bent back into a U shape, there are two front and rear portions thereof, a portion near the front end portion and a portion near the rear end portion of the above-mentioned lower rail 11. The locking claws 12D and 12E, which are locked by hitting the locking claws 11D and 11E respectively formed in the sliding direction, are formed in an upright shape. These locking claws 12D and 12E are formed by dividing the through grooves 12C formed at the central portions of the left and right upper side fin portions 12B described above into each portion avoiding the front and rear sides.

The lock spring 13 is formed by bending a wire rod such as steel into a substantially U-shape in a plan view extending in a long shape in the front-rear direction. The lock spring 13 described above is formed as a folded-back portion in which the rear end portion 13B is folded back in a substantially U-shape in a plan view. Then, the middle portion of each line portion extending from the folded rear end portion 13B of the lock spring 13 to the front side in a pair on the left and right is bent in a wavy shape toward the outside in the seat width direction. The locked lock portion 13C is formed. Further, the front end portion 13A of each wire portion of the lock spring 13 described above has a shape that is bent so as to project outward in the seat width direction.

In the lock spring 13 described above, each portion of the tip portion of the front end portion 13A of each of the left and right line portions bent outward in the seat width direction is a vertical wall in the front region of each upper side fin portion 12B of the above-mentioned upper rail 12. It is set as a state in which it is inserted into each through hole 12Ba formed in the portion while being elastically squeezed from the inside and rotatably pin-connected. Further, the lock spring 13 described above is formed by having the folded portions on both corners of the rear end portion 13B described above being cut inward from the standing wall portion of the rear region of each upper side fin portion 12B of the upper rail 12 described above. It is set in a state where it is hooked from the upper side and rotatably pin-connected to each of the hooked pieces 12Bb.

Then, in the lock spring 13 described above, the left and right lock portions 13C described above are inside each through groove 12C formed at the center of the left and right upper side fin portions 12B of the upper rail 12 in the front-rear direction. It is assembled in a state where it is elastically squeezed from the outside and pulled out to the outside. Each of the above-mentioned through grooves 12C has a shape having a comb-shaped slit through which each of the lock portions 13C of the lock spring 13 passed through them can be individually elongated toward the upper side.

As described above, the lock spring 13 has a free state because the front end portion 13A and the rear end portion 13B are pin-connected to the upper rail 12 so as to be rotatable in the height direction at both ends. Then, by the restoring action of the spring-forced force itself, each of the above-mentioned lock portions 13C is passed from the lower side into each of the slits extending in a comb shape in each through groove 12C of the upper rail 12 from the front and rear sides. It is designed to be held in a supported state.

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

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

The lock spring 13 described above is pushed downward by the lock portion 13C when the loop handle 5 described above is operated (see FIGS. 14 to 18) or the boarding / alighting lever 6 is operated (FIGS. 19 to 25). It is bent so that it can be removed downward from the lock groove 11C of the lower rail 11. As a result, the slide lock state of the upper rail 12 via the lock spring 13 is released, and the upper rail 12 can be slid in the front-rear direction with respect to the lower rail 11. After that, when the operation of the loop handle 5 or the boarding / alighting lever 6 that has been operated is released, the lock spring 13 enters the lock groove 11C of the lower rail 11 again by the spring urging force as shown in FIG. 13, and the upper rail 12 The slide is returned to the locked state.

At that time, when the slide position of the upper rail 12 is such that the lock groove 11C of the lower rail 11 is not located at the position where the lock portion 13C of the lock spring 13 is restored, that is, the shelf surface between the lock grooves 11C is located. The lock portion 13C is returned only to the position where it hits the shelf surface, and is not in the slide lock state. However, by shifting the slide position of the upper rail 12 from the slide position to either the front or rear side, the lock portion 13C is aligned with the lock groove 11C of the lower rail 11 and enters the lock groove 11C (slide lock). It is possible to switch to the state).

The above is the specific configuration of each slide rail 10 shown in FIG. Of 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. According to the above configuration, the slide rail 10 on the inner side in the vehicle width direction is operated to release the lock spring 13 via the operation mechanism 30 described above by operating the boarding / alighting lever 6 described above. ..

Foreign matter such as gravel that has fallen on the bottom surface of the memory rail 21A due to the shape that is widely grounded upward in the left-right direction and overhangs in the left-right direction is directly below the memory piece 21B. It is possible to prevent it from getting inside. Specifically, the wide grounding portions 21Cd and 21Ce have standing walls 21Cd1 and 21Ce1 that rise from the grounding region even when the memory piece 21B is pushed down, so that foreign matter such as gravel can reach the wide grounding portions 21Cd and 21Ce. It is possible to appropriately prevent the memory piece 21B from getting over and entering the area directly under the memory piece 21B.

Therefore, the above-mentioned wide grounding portions 21Cd and 21Ce are widely grounded in the left-right direction on the bottom surface of the memory rail 21A even when the above-mentioned memory piece 21B is pulled in the front-rear direction as shown in FIG. 17 after the above-mentioned release operation. It is possible to appropriately prevent foreign matter such as gravel from entering the region directly under the memory piece 21B while maintaining the state of being in the state of being gravel.

The vertical wall 21Ce1 formed on the wide ground contact portion 21Ce on the rear side described above is formed so as to have a lower rising height from the ground contact surface than the vertical wall 21Cd1 formed on the wide ground contact portion 21Cd on the front side. According to the above configuration, the vertical wall 21Ce1 formed on the wide ground contact portion 21Ce on the rear side is shown in FIGS. 25 and 31 even if the vertical wall 21Ce1 is formed so as to rise from a position rearward from the rear end of the memory piece 21B. As described above, the trigger link 22A does not hinder the movement of the trigger link 22A pressed against the rear end of the memory piece 21B from the rear side. Here, the above-mentioned trigger link 22A corresponds to the "link member" of the present invention.

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

The overhanging surface regions 21Cd2 and 21Ce2 of the wide grounding portions 21Cd and 21Ce described above have an asymmetrical shape in the front-rear lengths L1 and L2 of the memory piece 21B described above, so that the gap T1 is widely set overhanging on the front side. The surface region 21Cd2 is formed so that the overhang in the front-rear direction toward the memory piece 21B is longer than that of the rear overhang surface region 21Ce2 in which the gap T2 is set narrower. According to the above configuration, the wide grounding portions 21Cd and 21Ce are within the region directly below the memory piece 21B from the gaps T1 and T2 in accordance with the width of the gaps T1 and T2 in the front-rear direction formed between the wide grounding portions 21Cd and 21Ce. It is possible to appropriately prevent foreign substances such as gravel from entering.

<< Operation of memory body 21 >>
As shown in FIG. 13, in the memory body 21 described above, in the initial state in which the seat position described above is placed in a certain storage position before the change of the memory piece 21B, each engaging claw 21Ba2 of the memory piece 21B described above is stored in memory. The memory piece 21B is held in a fixed position in the front-rear direction as it is fitted into each engagement hole 21Ab of the rail 21A. Then, as shown in FIGS. 14 to 18, when the loop handle 5 is operated from the initial state to adjust the seat position, the memory piece 21B described above engages with the memory rail 21A. It is designed so that it is removed from the combined state and moved in the direction of movement of the seat position.

Specifically, in the memory body 21 described above, the loop handle 5 described above is pulled up from the initial state shown in FIG. 14 to the shape shown in FIGS. 15 to 16, so that the memory piece 21B described above may perform an operation described later. The rotating member 38 of the mechanism 30 pushes the leaf spring 21C downward against the spring urging force of the leaf spring 21C. As a result, each engaging claw 21Ba2 of the memory piece 21B is removed downward from each engaging hole 21Ab of the memory rail 21A, and the memory piece 21B can move in the front-rear direction with respect to the memory rail 21A. Can be switched to.

Therefore, as shown in FIG. 17, the seat position is lowered to the rear side while maintaining the operating state of the loop handle 5, so that the member is taken to the mounted portion 21Bb of the memory piece 21B. A pressing force from the front side is applied from 38, and the memory piece 21B is pushed and moved to a position corresponding to the moving position of the seat position. Further, when the seat position is moved to the front side while maintaining the operation state of the loop handle 5 described above, the memory piece 21B described above is pressed against the mounted portion 21Bb described above from the rear side. The trigger link 22A receives a pressing force from the rear side and is pushed to a position corresponding to the moving position of the seat position.

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

On the other hand, in the memory body 21 described above, as shown in FIGS. 19 to 25, when the boarding / alighting lever 6 is operated to adjust the seat position from the initial state described above, the memory piece 21B described above is in contact with the memory rail 21A. It is designed to be left in place in a way that allows the movement of the seat position to escape without being disengaged from the engaged state. Specifically, in the memory body 21 described above, the loading / unloading lever 6 described above is operated from the initial state shown in FIG. 19 to the shape shown in FIG. The memory piece 21B is pulled up to a position higher than the mounted portion 21Bb by being operated so as to be pulled up instead of being pushed into the memory piece 21B.

Therefore, as shown in FIG. 21, the memory piece 21B follows the movement of the seat position even if the seat position is lowered to the rear side while maintaining the operating state of the boarding / alighting lever 6 from the above operating state. It is left in place without any. Therefore, in the memory body 21 described above, as shown in FIG. 22, even if the operation of the boarding / alighting lever 6 is returned at the moving position of the seat position described above, the memory piece 21B is left behind at the position before the seat position is changed. It is supposed to be held as a state.

In the memory body 21 described above, as shown in FIG. 23, even if the boarding / alighting lever 6 is operated again at the position where the seat position is changed to the rear side, the memory piece 21B is in the position before the seat position is changed. It is retained as being left behind. Then, as shown in FIG. 24, the memory body 21 described above is lifted by the memory piece 21B by returning the seat position to the front side while maintaining the operating state of the boarding / alighting lever 6. The trigger link 22A of the detection operating body 22, which will be described later, is pressed against the portion 21Bb from the rear side, and the trigger link 22A is pushed around as the seat position is returned to the front side.

As shown in FIG. 25, the memory body 21 is moved by the above-mentioned operation to cancel the operation state of the boarding / alighting lever 6 through the operation of the detection operation body 22. At a position where the mounted portion 21Bb is passed over to the front side, the mounted portion 21Bb is dropped into the front portion of the mounted portion 21Bb and returned to the same state as the initial state applied.

On the other hand, in the memory body 21 described above, the loop handle 5 is operated as shown in FIG. 30 from a state in which the seat position is moved backward by operating the boarding / alighting lever 6 described above, leaving the memory piece 21B described above in FIG. 22. When the seat position may be returned to the front side in the operating state, as shown in FIG. 31, the above-mentioned rotating member 38, which is in the operating state pushed down by the operation of the loop handle 5, is a memory piece. The memory piece 21B is pressed against the mounted portion 21Bb of the 21B from the rear side, and the memory piece 21B is pushed and tilted in a rearward downward shape against the spring urging force of the leaf spring 21C.

Due to the backward tilting, the memory piece 21B is in a state of accepting the forward movement of the traveling member 38 in a form in which the traveling member 38 rides on the mounted portion 21Bb. Then, in the memory piece 21B, the rear end of the mounted portion 21Bb is pushed down by the riding of the traveling member 38 onto the mounted portion 21Bb with the progress of the forward movement of the seat position. The rear fulcrum 21Bc1 forming the bottom-side posture holding portion 21Bc is first tilted so as to bottom out on the bottom surface of the memory rail 21A.

Then, as shown in FIG. 32, the memory piece 21B described above is at the maximum on the center side due to the progress of the forward movement of the traveling member 38 on the mounted portion 21Bb accompanying the forward movement of the seat position. The fulcrum 21Bc2 is also sunk to a position where it bottoms out on the bottom surface of the memory rail 21A. However, even if the memory piece 21B described above is submerged as described above, the engaging claws 21Ba2 on the front end side thereof are connected to the memory rail 21A due to the bottoming of both fulcrums 21Bc1, 21Bc2 of the posture holding portion 21Bc described above.

The cancel link 22B described above is rotatably connected to a portion extending from the connecting portion with the shaft pin 22Ba to the lower front side by a shaft pin 22Bb1 in which the kick cam 22Bb further directs the axis in the seat width direction. It is said that it has been configured.

The kick cam 22Bb described above is always rotated counterclockwise toward the paper surface of FIG. 13 around the shaft pin 22Bb1 by the urging force of a spring (not shown) hooked between the kick cam 22Bb and the cancel link 22B described above. It is said to be in a state of being urged. Due to the above urging, the kick cam 22Bb is always rotated so that the locking piece 22Bb2 formed so as to project from the outer peripheral portion in the seat width direction is abutted against the locking projecting piece 22Bc formed so as to project from the cancel link 22B. At the position, the rotational posture with respect to the cancel link 22B is held in a locked state.

The kick cam 22Bb described above has a kick protrusion 22Bb3 that protrudes from the cancel link 22B so as to extend its shape further forward and downward in a state where the rotational posture with respect to the cancel link 22B described above is locked. It is said that. As shown in FIG. 21, the kick cam 22Bb is engaged with the operation mechanism 30 described later on the movement locus of the cancel link 22B when the cancel link 22B is rotated around the shaft pin 22Ba in the counterclockwise direction shown in the drawing. When the kicked pin 33C of the decam 33 is positioned, the cancel link 22B is rotated clockwise with respect to the cancel link 22B about the shaft pin 22Bb1 so as to avoid interference with the kicked pin 33C. It is designed to function to escape the rotational movement of.

However, as shown in FIG. 24, when the kick cam 22Bb is rotated so as to be returned in the clockwise direction shown around the shaft pin 22Ba from the position where the cancel link 22B has been rotationally moved, as shown in FIG. , The kick pin 33C of the engagement / disengagement cam 33 of the operation mechanism 30 described later, which is located on the movement locus, is pushed and kicked by the integral rotation with the cancel link 22B, and the engagement / disengagement cam 33 is engaged with the operation cam 34. It is designed to work to remove it from the combined state.

The shaft pin 22Cb can be rotated with respect to the base plate 31 within a range in which the shaft pin 22Cb can pass through the elongated hole 31D. The elongated hole 31D described above is formed in a curved shape in an arc shape drawn at the center of the shaft pin 22Ba, which is the center of rotation of the cancel link 22B described above.

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

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

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

<< Operation of detection operating body 22 >>
In the detection operating body 22 described above, as shown in FIG. 13, in the initial state in which the seat position described above is placed in a certain storage position before the change of the memory piece 21B, the leg side link 22Ab of the trigger link 22A described above is described above. The head-side link 22Ac and the leg-side link 22Ab centered on the shaft pin 22Aa are pressed against the rear surface portion of the mounted portion 21Bb of the memory piece 21B by the spring-forced force (not shown). The integrated clockwise rotational movement is held in a state of being stopped at an intermediate position.

As shown in FIGS. 14 to 18, the above-mentioned detection operating body 22 is not operated at all even if the above-mentioned loop handle 5 is operated, and the state changes between before and after the operation of the loop handle 5. There is no such thing. However, as shown in FIGS. 19 to 25, the above-mentioned detection operating body 22 moves the seat position leaving the memory piece 21B when the boarding / alighting lever 6 is operated to adjust the seat position from the above-mentioned initial state. Along with this, it is moved in a form of detecting a state of being separated from the memory piece 21B and a state of being pressed against the memory piece 21B.

Specifically, the detection operating body 22 described above is not particularly operated even if the boarding / alighting lever 6 described above is operated from the initial state shown in FIG. 19 to the shape shown in FIG. 20. However, as shown in FIG. 21, the above-mentioned detection operating body 22 is moved to the rear side by operating the above-mentioned boarding / alighting lever 6 leaving the memory piece 21B, and thus the leg side of the above-mentioned trigger link 22A. The link 22Ab is removed from the contact state with the rear surface portion of the mounted portion 21Bb of the memory piece 21B, and the head side link 22Ac and the leg side link 22Ab are integrated by a spring-forced force (not shown). The leg side link 22Ab is turned in the clockwise direction shown in the figure so as to kick out the leg side link 22Ab about the shaft pin 22Aa.

The rotational movement by the spring-forced force in the clockwise direction shown around the shaft pin 22Aa of the trigger link 22A described above is the elongated hole 31C through which the shaft pin 22Ca connected to the upper end of the head side link 22Ac described above is passed. It is locked by hitting the rear end and being stopped. Then, by the rotational movement of the trigger link 22A, the cancel link 22B is rotationally operated so as to be pulled in the counterclockwise direction shown around the shaft pin 22Ba via the operation link 22C connected to the trigger link 22A.

At that time, the cancel link 22B is provided with respect to the kick pin 33C of the engagement / disengagement cam 33 of the operation mechanism 30 described later, which is in a state of protruding to a position on the movement locus with the operation of the boarding / alighting lever 6 described above. , The kicking piece 22Bb3 of the kick cam 22Bb is rotated so as to be pressed from above. However, in the above-mentioned cancel link 22B, when the kicking tip 22Bb3 of the kick cam 22Bb is pressed against the kicked pin 33C of the engagement / disengagement cam 33 from the rotation direction, the kick cam 22Bb is opposed to the cancel link 22B by the shaft pin 22Bb1. It is possible to rotate in the clockwise direction shown in the figure against the spring-forced force (not shown) around the center to a position where it can pass through the kicked pin 33C while avoiding contact with the kicked pin 33C. ..

Then, when the cancel link 22B described above is rotated to a position where it can pass through the kicked pin 33C described above, the kick cam 22Bb described above is applied to the locking projecting piece 22Bc of the cancel link 22B by a spring urging force (not shown). It is designed to return to the posture state of. As shown in FIG. 22, the above-mentioned detection operating body 22 is not particularly operated even if the operation of the boarding / alighting lever 6 is returned at that position after the above-mentioned seat position is moved backward. Further, as shown in FIG. 23, the above-mentioned detection operating body 22 is not particularly operated even if the boarding / alighting lever 6 is operated again at the position where the above-mentioned seat position is changed to the rear side.

However, as shown in FIG. 24, in the detection operating body 22 described above, the seat position is returned to the front side while maintaining the operating state of the boarding / alighting lever 6, so that the leg side link 22Ab of the trigger link 22A described above is released. It is operated so as to be pressed against the mounted portion 21Bb of the memory piece 21B from the rear side and pushed around the shaft pin 22Aa in the counterclockwise direction shown in the movement as the seat position is returned to the front side. ..

By the above operation, in the detection operating body 22, the rotation of the trigger link 22A described above is transmitted to the cancel link 22B via the operation link 22C, and the cancel link 22B is pushed in the clockwise direction shown around the shaft pin 22Ba. Rotate. By this rotation, the cancel link 22B is pressed from below the kicking piece 22Bb3 of the kicking cam 22Bb against the kicked pin 33C of the above-mentioned engagement / disengaging cam 33 overhanging at a position on the movement locus.

In that case, even if the above-mentioned kick cam 22Bb is pressed against the kicked pin 33C from below, the cancel link 22B is counterclockwise shown around the shaft pin 22Bb1 with respect to the cancel link 22B. It is designed to maintain an integral state with the cancel link 22B without rotating in the direction. Therefore, as the rotational movement of the cancel link 22B progresses, the kicking tip 22Bb3 of the kicking cam 22Bb pushes and kicks the kicked pin 33C to disengage the engaging / disengaging cam 33 from the engagement state with the operation cam 34 described later. It is designed to be operated.

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

The detection operating body 22 described above operates so as to unlock and return the lock spring 13 by pressing the trigger link 22A against the mounted portion 21Bb of the memory piece 21B from the rear side as described above. By retracting the seat position to the boarding / alighting support position near the rear most as described above, the head side link 22Ac of the trigger link 22A described above in FIG. 24 projects like an eaves of the stopper bracket 15 described above in FIG. It is applied to the 15A from the front side, and similarly operates to unlock and return the lock spring 13.

The detection operating body 22 configured as described above is further moved to the rear side from the state where the seat position is placed in the storage position before the change of the memory piece 21B shown in FIG. 20 by the operation of the boarding / alighting lever 6 described above. Instead, as shown in FIG. 26, when the memory piece 21B is moved to the front side, the movement can be released without overloading the trigger link 22A pressed from the rear side to the memory piece 21B described above. It is equipped with an avoidance mechanism 22M.

Specifically, the above-mentioned overload avoidance mechanism 22M has a memory as shown in FIG. 26 from the position in the initial state (see FIG. 20) in which the above-mentioned trigger link 22A is pressed against the memory piece 21B from the rear side. The trigger link 22A and the cancel link 22B that rotates in response to the rotation of the trigger link 22A when the force is pressed against the piece 21B from the rear side and is pushed around the shaft pin 22Aa in the counterclockwise direction shown in the figure. And, respectively, are configured by a mechanism that allows the above-mentioned input to escape in the direction of rotation against the spring-forced force (not shown).

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

By the overload avoidance mechanism 22M described above, the detection operating body 22 rides on the memory piece 21B in a forward leaning posture with the trigger link 22A moving forward from the initial position of the seat position described above. It slides on the piece 21B to a position where it gets over the front side. Then, as shown in FIG. 27, when the trigger link 22A gets over the memory piece 21B to the front side, the rotational posture of the trigger link 22A with respect to the memory piece 21B due to a spring-forced force (not shown). The leg side link 22Ab is returned to the shape of kicking forward, which is the same as the state shown in FIG. 21 in which the contact from the rear side is removed.

Further, in the detection operating body 22 described above, the seat position of the trigger link 22A is the memory piece 21B as shown in FIG. 28 from the state position where the trigger link 22A shown in FIG. 27 exceeds the memory piece 21B to the front side. Even when it is moved to the rear side so as to return to the rear side, it is provided with a relief mechanism 22N that can release the movement without overloading the trigger link 22A that is pressed against the memory piece 21B from the front side. ing.

Specifically, the above-mentioned relief mechanism 22N receives an input of a force that is pushed around the shaft pin 22Aa in the clockwise direction by pressing the above-mentioned trigger link 22A against the memory piece 21B from the front side. At that time, the leg-side link 22Ab of the trigger link 22A is configured by a mechanism that allows the leg-side link 22Ab to escape in the direction of rotation that receives the above input independently against the spring-forced force (not shown) in the form of leaving the head-side link 22Ac. There is.

That is, in the above-mentioned trigger link 22A, the locking piece 22Ac1 of the above-mentioned leg-side link 22Ab is the locking piece 22Ac1 of the above-mentioned head-side link 22Ac with respect to the rotation in the counterclockwise direction shown around the shaft pin 22Aa with respect to the head-side link 22Ac. It is said that the leg side link 22Ab is hooked between the head side link 22Ac and the head side link 22Ac for rotation in the opposite direction. It is possible to rotate while leaving the head side link 22Ac against the spring-forced force of.

Therefore, due to the relief mechanism 22N having the above configuration, the detection operating body 22 causes the leg-side link 22Ab of the trigger link 22A to be placed on the memory piece 21B with respect to the head-side link 22Ac as the seat position moves backward. It slides on the memory piece 21B to the rear side in a shape that bends in a middle-folded shape and rides on the memory piece 21B. Then, as shown in FIG. 29, the detection operating body 22 is in a state where the leg-side link 22Ab of the trigger link 22A is mounted on the mounted portion 21Bb of the memory piece 21B, and the memory is described above. The piece 21B is pushed and tilted in a backward tilted manner in the same manner as described above in FIG. 31 against the spring urging force of the leaf spring 21C by the action of the force pushed from above the piece 21B.

Then, as shown in FIG. 29, the leg-side link 22Ab of the trigger link 22A described above corresponds to FIG. 20 before moving the seat position forward due to the movement of the memory piece 21B being pushed and tilted backward. A position where the amount of movement to return to the position exceeds the mounted portion 21Bb by rotating in the counterclockwise direction shown around the shaft pin 22Aa while sliding on the inclined surface 21Bb1 of the mounted portion 21Bb of the memory piece 21B. It is rotated to the same state as the initial state pressed from the rear side against the mounted portion 21Bb of the memory piece 21B.
