The lock auxiliary member 40 will be described with reference to FIG.
The lock auxiliary member 40 may be arranged at a position (hereinafter, “lock position”; see FIG. 6) that engages with the striker 5 that is inserted into the insertion groove 13 by rotation.
The lock auxiliary member 40 has a base 41 including a center of rotation, an arm 42 extending from the base 41, and a protrusion 43 extending in a direction intersecting the arm 42 in the radial direction.

The arm 42 extends from a position deviated from the rotation center of the base 41. Specifically, when the lock auxiliary member 40 is in the lock position and the protrusion 43 is arranged, the arm 42 is arranged beside the insertion groove 13 and follows the insertion groove 13.

The protrusion 43 overlaps the second claw 34 when the lock auxiliary member 40 is in the locked position, and is arranged between the first groove 37 and the second groove 38.
The protrusion 43 has an inward surface 43a that faces inward in the radial direction and an outward surface 43b that faces outward in the radial direction. When the lock member 30 and the lock auxiliary member 40 are in the locked position, the protrusion 43 has the outward surface 43b of the protrusion 43 located radially outward from the outward surface 37b of the first groove 37, and the protrusion 43. The inward surface 43a of 43 is located radially inward with respect to the inward surface 38a of the second groove 38.

The lock auxiliary member 40 is provided with an engagement hole 44 through which the engagement pin 36 of the lock member 30 is inserted. The engagement hole 44 is formed in an oval shape and extends along a circle centered on the rotation center line of the shaft member 25. The engagement hole 44 has a first end surface 44a on the engagement direction DA side and a second end surface 44b on the release direction DB side on the inner peripheral surface. When the lock member 30 rotates in the release direction DB (for example, rotation based on the entry of the striker 5), the engagement pin 36 comes into contact with the second end surface 44b of the engagement hole 44, and the lock member 30 and the lock auxiliary member 40 come into contact with each other. Together, it rotates in the release direction DB. When the lock auxiliary member 40 rotates in the release direction DB (for example, rotation based on the operation of the operation pole 4), the first end surface 44a of the engagement hole 44 comes into contact with the engagement pin 36, and the lock member 30 and the lock auxiliary member 40 come into contact with each other. And are integrated and rotate in the release direction DB.

The engaging pin 36 and the engaging hole 44 have the following arrangement relationship. When the locking member 30 and the locking auxiliary member 40 are in the locking position, the engaging pin 36 is located between both ends of the engaging hole 44. Therefore, when the striker 5 enters the lock mechanism 10 and the striker 5 and the lock member 30 come into contact with each other and the lock member 30 rotates in the release direction DB, the lock auxiliary member 40 is released after the rotation of the lock member 30. Rotate in the direction DB. On the other hand, when the lock auxiliary member 40 is rotated by the operation of the first lever 50 or the second lever 60, the lock member 30 rotates in the release direction DB behind the rotation of the lock auxiliary member 40.

Further, the lock auxiliary member 40 is provided with an engaging protrusion 45 extending along the extension direction of the shaft member 25. The engaging protrusion 45 is pushed by the first lever 50 and the second lever 60. Further, the base 41 of the lock auxiliary member 40 is provided with a retaining portion 41a to which the second urging member 72 is attached. The lock auxiliary member 40 is urged by the second urging member 72 in the engaging direction DA, which is the direction in which the lock auxiliary member 40 can be engaged with the striker 5. The other end of the second urging member 72 is connected to the first lever 50.

Next, the pinching of the first pinched portion 5a of the striker 5 by the lock member 30 and the lock auxiliary member 40 will be described.
When the striker 5 is inserted into the insertion groove 13 of the lock mechanism 10 and the first sandwiched portion 5a of the striker 5 is inserted into the first groove 37 of the lock member 30, the first sandwiched portion 5a of the striker 5 is a lock member. The inward surface 37a of the first groove 37 of 30 and the outward surface 43b of the protrusion 43 of the lock auxiliary member 40 come into contact with each other. Then, the lock member 30 and the lock auxiliary member 40 move in opposite directions to each other. On the other hand, since the lock member 30 and the lock auxiliary member 40 are supported by the shaft member 25, the moving distance thereof is the clearance (the gap between the lock member 30 and the shaft member 25, the lock auxiliary member 40 and the shaft member 25). The movement of the lock member 30 and the lock auxiliary member 40 is restricted only by the amount of the gap between the lock member 30 and the lock member 40. Therefore, when the first pinched portion 5a of the striker 5 penetrates deeply into the first groove 37, the lock member 30 and the lock auxiliary member 40 do not move, and the first pinched portion 5a of the striker 5 locks with the lock member 30. It is sandwiched by the auxiliary member 40. When the striker 5 is sandwiched in this way, the lock member 30 and the lock auxiliary member 40 are fixed (they do not move), so that the striker 5 is engaged with the lock mechanism 10 without rattling. ..
The case where the first sandwiched portion 5a of the striker 5 is inserted into the second groove 38 of the lock member 30 is the same as the case where the first groove 37 is inserted. Further, the mode of sandwiching the second sandwiched portion 5b is the same as the mode of sandwiching the first sandwiched portion 5a.

The locking mechanism 10, the striker 5, and the engagement mode will be described with reference to FIGS. 9 to 11.
When the striker 5 has two sandwiched portions 5a and 5b as in the present embodiment, the lock mechanism 10 can be engaged with the striker 5 at two positions as follows. As described above, the lock mechanism 10 can sandwich the striker 5 at two positions (first groove 37 and second groove 38) without rattling. Therefore, the lock mechanism 10 can engage with the striker 5 in a maximum of four steps when there is no restriction on the entry of the striker 5. In the present embodiment, since the access of the striker 5 is restricted and the length of the lock member 30 is set to the specified length, the striker 5 can be engaged with the striker 5 in three stages due to the structure of the lock member 30.

As shown in FIG. 9, the first stage lock is a state in which the first sandwiched portion 5a of the striker 5 is inserted into the first groove 37. In the first-stage lock, the first sandwiched portion 5a of the striker 5 is sandwiched between the inward surface 37a of the first groove 37 and the outward surface 43b of the protrusion 43 (see FIG. 6).
As shown in FIG. 10, the second-stage lock is a state in which the first sandwiched portion 5a of the striker 5 is inserted into the second groove 38. In the second-stage lock, the first sandwiched portion 5a of the striker 5 is sandwiched between the outward surface 38b of the second groove 38 and the inward surface 43a of the protrusion 43 (see FIG. 6).
As shown in FIG. 11, the third-stage lock is a state in which the second sandwiched portion 5b of the striker 5 is inserted into the first groove 37. In the third-stage lock, the second sandwiched portion 5b of the striker 5 is sandwiched between the inward surface 37a of the first groove 37 and the outward surface 43b of the protrusion 43 (see FIG. 6). Further, the first sandwiched portion 5a of the striker 5 is inserted into the third groove 39. In the third-stage lock, the first pinched portion 5a does not contact the third groove 39, or the first pinched portion 5a contacts the third groove 39 without receiving a force from the third groove 39. ..

As described above, since the lock member 30 can be engaged with the striker 5 in three stages due to the structure of the lock member 30, the seat 1 can be fixed to the vehicle in several postures in which the inclination of the seat back 3 is different.

The first lever 50 will be described with reference to FIGS. 12 and 13.
The first lever 50 rotates the lock member 30 and the lock auxiliary member 40 in the release direction DB. As a result, the engagement between the lock member 30 and the lock auxiliary member 40 and the striker 5 is released. The first lever 50 is rotatably attached to the base plate 20 with a pin 54.
The first lever 50 has a base 51 including a center of rotation, a first arm 52 extending from the base 51, and a second arm 53 extending from the base 51 in a direction different from that of the first arm 52. The base portion 51 is provided with a retaining portion 51a to which the second urging member 72 is connected. An operation pole 4 is connected to the end of the second arm 53.

The base 51 of the first lever 50 is arranged on the same side as the lock auxiliary member 40 with respect to the insertion groove 13, and is arranged farther from the insertion groove 13 than the lock auxiliary member 40. The first arm 52 of the first lever 50 hits the rear surface of the engaging protrusion 45 in the movement of the engaging protrusion 45 in the releasing direction DB so that the engaging protrusion 45 can be pushed toward the releasing direction DB. Get in touch. The first lever 50 is urged by the second urging member 72 so as to rotate in a direction opposite to the urging direction of the lock auxiliary member 40. Therefore, since the first arm 52 rotates in the direction away from the engaging protrusion 45, the lock auxiliary member 40 is located at the lock position. On the other hand, when the first lever 50 rotates so that the first arm 52 pushes the engaging protrusion 45 by the operation of the operation pole 4, the lock auxiliary member 40 and the lock member 30 are released in the release direction. Rotate to DB.

The second lever 60 will be described with reference to FIGS. 14 to 16.
The second lever 60 rotates the lock member 30 and the lock auxiliary member 40 in the release direction DB. As a result, the engagement between the lock member 30 and the lock auxiliary member 40 and the striker 5 is released. The second lever 60 is rotatably attached to the base plate 20 with a pin 67. The second lever 60 is rotated by operating the unlocking cable 191. The unlocking cable 191 (see below) is connected to the retaining portion 60a of the second lever 60.

The second lever 60 has a base 61 including a center of rotation and an arm 62 extending from the base 61. The arm 62 is bent so as to avoid the insertion groove 13 of the base member 11, and is further bent near the tip end. Specifically, the arm 62 has a first extension portion 63 extending from the base portion 61, a second extension portion 64 extending from the first extension portion 63 and extending so as to intersect the extension direction of the first extension portion 63, and a second extension portion 64. It has a third extension portion 65 extending from the extension portion 64 and extending so as to intersect the extension direction of the second extension portion 64. A sliding contact surface 66 with which the engaging protrusion 45 is in sliding contact is provided from the vicinity of the connection between the second extension portion 64 and the third extension portion 65 to the third extension portion 65. The sliding contact surface 66 is bent. The sliding contact surface 66 includes a first sliding contact surface 66a up to the bend and a second sliding contact surface 66b beyond the bent portion.

The first sliding contact surface 66a and the second sliding contact surface 66b move the engaging protrusion 45 in the release direction DB by rotating the second lever 60 by operating the unlocking cable 191 (see below). Due to the bent structure of the sliding contact surface 66, the moving distance of the engaging protrusion 45 with respect to the rotation angle of the second lever 60 in the sliding contact between the second sliding contact surface 66b and the engaging protrusion 45 is the first sliding contact surface 66a. It is shorter than the moving distance in the sliding contact between the engaging protrusion 45 and the engaging protrusion 45.

The second lever 60 is urged by the third urging member 73 so as to rotate in the same direction as the urging direction of the lock auxiliary member 40.
The unlocking cable 191 is connected to the retaining portion 60a of the second lever 60. The unlocking cable 191 transmits the power of the operating device 150 attached to the seat 1 or the vehicle to the second lever 60. The second lever 60 rotates in the direction opposite to the urging direction by the operation of the unlocking cable 191.

The base 61 of the second lever 60 is arranged on the side opposite to the lock auxiliary member 40 with respect to the insertion groove 13. The third extension portion 65 of the second lever 60 is behind the engaging protrusion 45 in the movement of the engaging protrusion 45 in the releasing direction DB so that the engaging protrusion 45 can be pushed out to the releasing direction DB. Be placed. When the power from the unlocking cable 191 is not applied to the second lever 60, the force with which the arm 62 of the second lever 60 pushes the engaging protrusion 45 in the releasing direction DB is weak. Therefore, the lock auxiliary member 40 is located at the lock position. When the second lever 60 is rotated in the direction opposite to the urging direction by the operation of the unlocking cable 191, the first sliding contact surface 66a of the arm 62 of the second lever 60 pushes the engaging protrusion 45. As a result, the lock auxiliary member 40 and the lock member 30 rotate in the release direction DB. Further, when the second lever 60 rotates and the second sliding contact surface 66b of the arm 62 comes into contact with the engaging protrusion 45, the moving distance of the engaging protrusion 45 with respect to the rotation angle with respect to the second lever 60 becomes smaller. The rotation angles of the lock auxiliary member 40 and the lock member 30 are also reduced. By limiting the rotation angles of the lock auxiliary member 40 and the lock member 30 in this way, the size (area in front view) of the lock mechanism 10 can be limited.

The operation of the lock mechanism 10 will be described.
When the striker 5 enters the insertion groove 13 of the lock mechanism 10, the first pinched portion 5a of the striker 5 comes into contact with the outer surface 33a of the first claw 33 of the lock member 30. Then, since the outer surface 33a of the first claw 33 is inclined with respect to the insertion groove 13, the lock member 30 is pushed up by the striker 5 and rotates when the striker 5 enters. When the lock member 30 rotates, the lock auxiliary member 40 also rotates accordingly. As a result, the striker 5 goes further inward. When the rotation angle of the lock member 30 is in the first angle range, the striker 5 hits the second claw 34 because the second claw 34 is arranged in the insertion groove 13, and its entry is blocked. At this time, since the force of the striker 5 to push up the lock member 30 is weakened, the lock member 30 and the lock auxiliary member 40 rotate in the urging direction and return to the lock position. Then, the first sandwiched portion 5a of the striker 5 is sandwiched by the lock member 30 and the lock auxiliary member 40. As a result, the locked state becomes the first stage lock.
The transition from the first stage lock to the second stage lock, or the transition from the second stage lock to the third stage lock is performed by unlocking by operating the first lever 50 or the second lever 60. Is possible.

The movement regulation mechanism 80 will be described with reference to FIGS. 17 to 33.
As shown in FIG. 17, the movement regulation mechanism 80 includes a movement regulation member 90.

The movement regulation mechanism 80 further includes a positioning member 100 for positioning the movement regulation member 90. Further, the movement regulation mechanism 80 includes a feed mechanism 120 that operates based on the operation in the operation device 150. The feed mechanism 120 arranges the movement restricting member 90 at a target position by changing the engagement relationship between the movement restricting member 90 and the positioning member 100 based on the operation of the operating device 150.

Hereinafter, an example of the movement regulation mechanism 80 will be described.
As shown in FIGS. 17 and 18, the movement restricting mechanism 80 limits the rotation of the movement restricting member 90, the positioning member 100 attached to the base plate 20 via the mounting member 103, and the rotation restricting member 90. A member 110 and a feed mechanism 120 for moving the movement restricting member 90 to a target position are provided.

As described above, the movement restricting member 90 stops the movement of the striker 5 entering the insertion groove 13 (see FIG. 20). The movement restricting member 90 is rotatably attached to the positioning member 100 via the support shaft 81. The movement restricting member 90 has a main body portion 91 and an engaging member 93. The movement restricting member 90 is provided with an interlocking portion 95 (one element of the feed mechanism 120 described later) that is integrally interlocked with the movement restricting member 90 itself. The main body 91 of the movement restricting member 90 includes a base 91a including a center of rotation, a first arm 91b extending from the base 91a, and a second arm 91c extending from the base 91a in a direction different from that of the first arm 91b.

The first arm 91b of the movement restricting member 90 intersects the insertion groove 13. In the first arm 91b, a contact surface 92 with which the striker 5 abuts is provided on the opening side of the insertion groove 13 of the lock mechanism 10.

The second arm 91c is provided with an engaging member 93 that engages with the positioning member 100. The engaging member 93 is attached to the second arm 91c so as to be movable in the radial direction (the radial direction in the circle of the center of rotation of the second arm 91c). Specifically, the second arm 91c is provided with an elongated guide hole 91d that guides the engaging member 93 in the radial direction. The engaging member 93 is inserted into the guide hole 91d. The engaging member 93 rotates with the rotation of the movement restricting member 90, and moves in the radial direction according to the shape of the guide 102 described later.

The positioning member 100 includes a pair of guide plates 101. The pair of guide plates 101 have edges of the same shape. The pair of guide plates 101 are arranged in the direction along the rotation center line of the movement restricting member 90, and are attached to the base plate 20 via the attachment member 103. The edges of the pair of guide plates 101 form a guide 102 that guides the engaging member 93. The engaging member 93 is arranged on the guide 102 so that one end contacts the edge of one guide plate 101 and the other end contacts the edge of the other guide plate 101. The engaging member 93 moves along the guide 102. The engaging member 93 is pressed toward the guide 102 by the urging member 94 so as to move according to the shape of the guide 102. Specifically, the engaging member 93 and the support shaft 81 are connected by an urging member 94, and the engaging member 93 is pulled toward the support shaft 81. In the guide 102, a plurality of engaged portions 101a that engage with the engaging member 93 and barrier portions 101b are alternately arranged. The barrier portion 101b is provided between the plurality of engaged portions 101a and projects radially outward from the engaged portion 101a to prevent the engaging member 93 from moving. Since the engaging member 93 is urged inward in the radial direction by the urging member 94, when no force is applied to the movement restricting member 90 that supports the engaging member 93, the engaging member 93 is covered. It is arranged at the engagement portion 101a.

Further, the engaged portion 101a causes the contact surface 92 of the movement restricting member 90 to be positioned at any of a plurality of positions by engaging the engaging member 93 of the movement restricting member 90 with the engaged portion 101a. It is provided on the positioning member 100 so that it can be used. Then, the plurality of engaged portions 101a and the plurality of positions are associated with each other on a one-to-one basis. Therefore, when the engaging member 93 is arranged at the engaged portion 101a, the movement restricting member 90 is arranged at a position associated with the first groove 37 to the third groove 39 of the lock member 30. That is, the movement restricting member 90 engages with the positioning member 100 via the engaging member 93 to form a first position corresponding to the first groove 37 of the lock member 30 and a second position corresponding to the second groove 38. , Positioned at a third position corresponding to the third groove 39. Note that FIG. 20 shows an example (first position and second position) in which the movement restricting member 90 is arranged in the first groove 37 and the second groove 38.

As shown by the solid line in FIG. 20, when the movement restricting member 90 is positioned at the first position, the position of the contact surface 92 with respect to the first groove 37 is as follows. Due to the engagement between the engaging member 93 and the engaged portion 101a, the contact surface 92 of the movement restricting member 90 is arranged with the outward surface 37b of the first groove 37 when the locking member 30 is arranged at the locked position. It is arranged slightly behind the insertion groove 13. As a result, when the striker 5 enters the insertion groove 13, the striker 5 is prevented from entering deeper than the groove (for example, the first groove 37) in which the movement restricting member 90 is arranged. When the movement restricting member 90 is positioned at the second position or the third position, the positional relationship of the contact surface 92 with respect to the grooves 38 and 39 is the first when the movement restricting member 90 is positioned at the first position. It conforms to the positional relationship of the contact surface 92 with respect to the groove 37.

As shown in FIG. 18, the rotation limiting member 110 includes a base 111 including a rotation center, a first arm 112 extending from the base 111, and a second arm 113 extending from the base 111 in a direction different from that of the first arm 112.

The second arm 113 is provided with a hook 115 that engages with the engaging member 93. The hook 115 engages with the engaging member 93 in a state where the engaging member 93 is located at the end side in the radial direction in the guide hole 91d, and the engaging member 93 is radially outside the position. Engage so that it does not move toward you. Further, the hook 115 engages with the engaging member 93 so as to be separated from the engaging member 93 based on the rotation of the rotation limiting member 110 in a predetermined direction (rotation based on the contact of the striker 5). When the hook 115 engages with the engaging member 93, the engaging member 93 is sandwiched between the guide 102 and the hook 115 in the radial direction, and the movement in the radial direction is restricted.

The rotation limiting member 110 is urged by the urging member 116 as follows. In the rotation limiting member 110, the first arm 112 of the rotation limiting member 110 is arranged on the opening side of the insertion groove 13 of the lock mechanism 10 with respect to the first arm 91b of the movement restricting member 90, and the hook of the second arm 113. The 115 is urged to engage the engaging member 93 (see FIG. 21). That is, when the striker 5 is inserted into the insertion groove 13 of the lock mechanism 10, the rotation limiting member 110 hits the first arm 112 of the rotation limiting member 110 before the first arm 91b of the movement restricting member 90. They are arranged so that they touch each other. When the striker 5 is inserted into the insertion groove 13 of the lock mechanism 10 and the striker 5 abuts on the contact surface 114 of the first arm 112 to rotate the rotation limiting member 110, the hook 115 of the second arm 113 is engaged.

In the return operation, the transmission member 140 moves toward the reference position (rotates in the present embodiment) according to the operation direction of the operation lever 180, thereby causing the pressing member 124 to swing apart from the pressing member 124. The engagement between the pressing member 124 and the interlocking portion 95 is disengaged, and the support member 130 is returned to the support member reference position in a state where the movement restricting member 90 is maintained at the moved position.

The operation of the movement regulation mechanism 80 will be described with reference to FIGS. 21 to 30.
The operation of the movement restricting mechanism 80 is divided into an operation when the striker 5 enters and an operation when the movement restricting member 90 is moved by the operating device 150.

The operation of the movement restricting mechanism 80 when the striker 5 enters the insertion groove 13 will be described with reference to FIGS. 21 and 22.
FIG. 21 shows the initial state of the movement regulation mechanism 80 before the striker 5 enters the insertion groove 13.
The hook 115 of the rotation limiting member 110 engages with the engaging member 93 of the movement restricting member 90.
The engaging member 93 is arranged at the position of the engaged portion 101a, the movement in the radial direction is restricted with respect to the main body portion 91 of the movement restricting member 90, and the engaging member 93 does not exceed the barrier portion 101b. , The movement restricting member 90 does not move due to vibration or the like.

At this time, the transmission member 140 is arranged at the reference position. Further, the support member 130 is arranged at the support member reference position. As described above, the engaging projection 144 of the transmission member 140 contacts the second engaging surface 136, and the tip portion 142a of the first arm 142 contacts the first pressing surface 126 of the pressing member 124. The pressing teeth 128 of the pressing member 124 are arranged between the first engaging teeth 95a and the second engaging teeth 95b of the interlocking portion 95.

With reference to FIG. 22, the state of the movement restricting mechanism 80 when the striker 5 enters the insertion groove 13 will be described.
When the striker 5 enters the insertion groove 13, the first pinched portion 5a of the striker 5 comes into contact with the outer surface 33a of the first claw 33 of the lock member 30. As a result, the lock member 30 is pushed up and rotates against the urging force, and a passage through which the striker 5 enters the depth of the insertion groove 13 is opened. When the striker 5 enters the depth of the insertion groove 13, the striker 5 comes into contact with the first arm 112 of the rotation limiting member 110. Then, since the first arm 112 is pushed, the striker 5 then comes into contact with the movement restricting member 90. As a result, the striker 5 is stopped from entering. At this time, the striker 5 is arranged at a position where it can be inserted into the first groove 37 of the lock member 30 due to contact with the movement restricting member 90. Therefore, the lock member 30 smoothly returns to the lock position.
Further, when the first arm 112 of the rotation limiting member 110 is pushed by the contact between the striker 5 and the rotation limiting member 110 and the rotation limiting member 110 rotates, the hook 115 is moved from the engaging member 93 of the movement restricting member 90.

The operation of the movement regulation mechanism 80 based on the operation of the operation device 150 will be described with reference to FIGS. 23 to 30.
The following operation of the moving mechanism is an operation when the operating device 150 is operated with the striker 5 in the first groove 37.
FIG. 23 shows the first stage of operation of the movement regulation mechanism 80.
When the cable 192 for the first feed mechanism is pulled by the operating device 150, the transmission member 140 of the feed mechanism 120 rotates in the first direction DX. Then, the engaging projection 144 of the transmission member 140 comes into contact with the first engaging surface 135 of the engaging hole 134 of the supporting member 130, and the tip portion 142a of the first arm 142 comes from the first pressing surface 126 of the pressing member 124. Separated, the tip portion 143a of the second arm 143 comes into contact with the second pressing surface 127 of the pressing member 124 instead. Then, as described above, the pressing member 124 is restricted from swinging toward the second pressing surface 127 side.

When the outbound operation of the operation of the first operation direction DG in the operation device 150 is completed (see FIG. 27), the return operation in the direction opposite to the first operation direction DG (second direction DF) is performed. At this time, since the pull of the first feed mechanism cable 192 is weakened, the transmission member 140 and the support member 130 rotate in the direction opposite to the first direction DE so as to return to the reference position and the support member reference position. Since the movement restricting member 90 is positioned by the engagement between the engaging member 93 and the engaged portion 101a of the guide 102, the movement restricting member 90 does not rotate. When the support member 130 and the transmission member 140 rotate in the second direction DF with respect to the movement restricting member 90, the pressing member 124 comes into contact with the second engaging tooth 95b of the interlocking portion 95. Since the pressing member 124 is rotatable toward the first pressing surface 126, the pressing member 124 rotates with the rotation of the second direction DF of the support member 130 and the transmission member 140, and the pressing teeth 128 are the second engaging teeth. Get on 95b.

FIG. 29 shows the fifth stage of the operation of the movement regulation mechanism 80.
