In the vehicle seat slide device described in Patent Document 1, when the user rotates the handle shaft, a force that resists the urging of a total of two torsion coil springs attached to the handle shaft and the interlock shaft is handled by the handle shaft. Since it does not rotate unless it is added to, a large operating force is required to release the slide lock.
Similarly, in the vehicle seat slide device described in Patent Document 2, when the user rotates the operating lever, the tension coil spring attached to one of the operating levers, and the wire and the interlocking to the one operating lever. Since the operating lever does not rotate unless a force against the urging force of the two tension coil springs consisting of the tension coil springs attached to the other operating lever that operates via the lever is applied to the operating handle, a large operation is required. I needed power.

  Further, in the vehicle seat slide device described in Patent Document 1, by operating the handle shaft, the interlocking shaft on one upper rail side is rotated to move the interlocking wire substantially linearly in the seat width direction. Thus, in order to rotate the interlocking shaft on the other upper rail side, the members are interlocked by different motions of the rotational motion, the linear motion, and the rotational motion. Here, when switching from the rotational motion to the linear motion, since the positional displacement occurs in the vertical direction between the interlocking shaft and the interlocking wire, it is difficult to smoothly operate the lock lever.

  In addition, in the vehicle seat slide device described in Patent Document 2, since there are many components constituting the lock mechanism, costs for procurement of the components are incurred, and position adjustment between the components when assembling the components. There is a problem that the production cost is high because it is necessary.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to reduce the operation force necessary to release the slide lock, and to perform the slide lock operation and the slide lock release operation. An object of the present invention is to provide a smooth vehicle seat slide device.

Here, FIG. 4 is an exploded perspective view showing the first slide rail 2a, the first lock lever 61, the front support member 62, the rear support member 63, and the like. 5 is an exploded perspective view showing the first lock lever 61, the front support member 62, the rear support member 63, and the wire spring 64 in an enlarged manner, and FIG. 6A is a second view provided on the second slide rail 2b. FIG. 7B is a perspective view showing the lock lever 66, FIG. 7B is a perspective view showing the first lock lever 61 provided on the first slide rail 2a, and FIG. FIG. 8 is a cross-sectional arrow view showing the unlocked state of the first lock lever 61 shown in FIG.

The restriction mechanism 6B includes a first lock lever 61 as a first rotating body provided on the first slide rail 2a side, a front support member 62 and a rear support member 63 that support the first lock lever 61 from the front-rear direction, and a first A wire spring 64 that biases the first lock lever 61, a second lock lever 66 as a second rotating body provided on the second slide rail 2b side, and a front support member that supports the second lock lever 66 from the front-rear direction. 67, a rear support member 68, and a wire spring 69 for urging the second lock lever 66.
Each component provided on the first slide rail 2a side and each component provided on the second slide rail 2b side are formed symmetrically on the left and right sides of the seat, for easy understanding. Only the components provided on the first slide rail 2a side will be described.

(Configuration of the first lock lever)
As described above, the first lock lever 61 is supported by the front support member 62 and the rear support member 63, which will be described later, and is configured to be rotatable about an axial direction parallel to the sliding direction of the first rail 41. ing.
As shown in FIG. 5, the first lock lever 61 includes a flat plate-like main body 61 a, a lock claw 61 b that is connected to the main body 61 a and locks or unlocks the slide, and a front that protrudes upward from the front edge. An edge wall 61c and a rear edge wall 61e formed to protrude upward from the rear edge are provided.

  The lock claw 61b is composed of five blades formed in a comb shape, and protrudes downward from the outer side in the sheet width direction of the main body 61a and extends inward in the sheet width direction.

  The front edge wall 61c has a support hole 61d that is rotatably supported by a protruding support portion 62c of a front support member 62 described later. The support hole 61 d is formed in the thickness direction that is a direction parallel to the longitudinal direction of the first rail 41. Further, the front edge wall 61c has a protruding portion 61i that protrudes inward in the sheet width direction. The protrusion 61i receives an upward biasing force from a wire spring 64 described later. In other words, the upward direction is a direction in which the first lock lever 61 rotates in a direction in which the lock claw 61b engages with the lock hole 3a of the lower rail 3 to lock the sliding of the first rail 41. .

The rear edge wall 61e has a support hole 61f that is rotatably supported by a protruding support portion 63b of a rear support member 63 described later. The support hole 61f is formed in the thickness direction, which is a direction parallel to the longitudinal direction of the first rail 41, and on the extension of the support hole 61d.
Further, the rear edge wall 61e extends above the front edge wall 61c, and has an engagement hole 61g in the extending portion. The engagement hole 61 g is formed so as to penetrate in the thickness direction which is a direction parallel to the longitudinal direction of the first rail 41. The first lock lever 61 is rotatably connected to the base end portion 60b of the first link 60a described above by passing the engagement pin 60k shown in FIG. 2 through the engagement hole 61g.
Further, the rear edge wall 61e has a hook portion 61h extending outward and downward in the seat width direction from a portion extending upward from the front edge wall 61c. When the first lock lever 61 rotates a predetermined amount counterclockwise when viewed from the front side to the rear side, the hook portion 61h comes into contact with a rotation stopper 63c of the rear support member 63, which will be described later. This is to limit the amount of movement.

In the first lock lever 61 configured as described above, the lock claw 61b is formed in the through-hole of the first rail 41 as shown in FIG. 4f and the lock hole 4g are inserted and engaged with the lock hole 3a of the lower rail 3, whereby the sliding of the first rail 41 in the front-rear direction with respect to the lower rail 3 is locked.
Thus, the state in which the first lock lever 61 locks the sliding of the first rail 41 corresponds to the state in which the first lock lever 61 is rotated to the first restriction position of the present invention. Similarly, the state in which the second lock lever 66 locks the sliding of the second rail 42 corresponds to the state in which the second lock lever 66 is rotated to the second restricting position of the present invention.

Conversely, when the first lock lever 61 is rotated counterclockwise when viewed from the front side to the rear side, the lock claw 61b is extracted from the lock hole 3a of the lower rail 3 as shown in FIG. Then, the locking of sliding in the front-rear direction with respect to the lower rail 3 of the first rail 41 is released.
Thus, the state in which the first lock lever 61 releases the sliding lock of the first rail 41 corresponds to the state in which the first lock lever 61 is rotated to the first allowable position of the present invention. Similarly, the state where the second lock lever 66 unlocks the sliding of the second rail 42 corresponds to the state where the second lock lever 66 is rotated to the second permissible position of the present invention.

(Configuration of front support member, rear support member and spring)
The front support member 62 is for rotatably supporting the front side of the first lock lever 61. As shown in FIG. 5, the front support member 62 is formed in a flat plate shape as a whole, and a front support piece 62b on the front side is formed to protrude upward.
The front support piece 62 b is formed with a protruding support portion 62 c that protrudes rearward in a direction parallel to the longitudinal direction of the first rail 41. The protrusion support portion 62c fits into the support hole 61d of the first lock lever 61 described above, so that the front support member 62 and the rear support member 63 described later support the first lock lever 61 so as to be rotatable. Become.
Further, the front support member 62 has two through holes 62a formed in the plate thickness direction which is the vertical direction at the front and rear portions, and a notch 62d cut out at the inner side in the sheet width direction. Is formed.
The front support member 62 is attached to the first rail 41 in a state where the front support member 62 is attached along the upper surface of the first rail 41 by the fixture 4e passing through the two through holes 62a and the two attachment holes 4d of the first rail 41. 41 is fixed. In addition, a rear support member 63 to be described later is fastened together with a fixture 4e on the upper portion of the front support member 62 in the rear through hole 62a of the two through holes 62a.
Further, the notch 62d of the front support member 62 is formed to allow the lock claw 61b to pass through the through hole 4f of the first rail 41 located below the front support member 62.

The rear support member 63 is attached to the upper part on the rear side of the front support member 62 by being fastened together by a fixture 4e.
Specifically, the rear support member 63 has a through hole 63a penetrating in the vertical direction, and the fixture 4e passes through the through hole 63a, the through hole 62a of the front support member 62, and the through hole 4c of the first rail 41. By being fastened, the first rail 41 is fixed.

The rear support member 63 is formed with a projecting support portion 63 b that projects forward, which is a direction parallel to the longitudinal direction of the first rail 41. The protrusion support portion 63b fits into the support hole 61f of the first lock lever 61 described above, so that the rear support member 63 and the front support member 62 described above support the first lock lever 61 so as to be rotatable. Become.
The rear support member 63 is formed with a rotation stopper 63c that protrudes inward and upward from the inner side in the seat width direction. As described above, the rotation stopper 63c contacts the hook portion 61h of the first lock lever 61 when the first lock lever 61 rotates a predetermined amount counterclockwise when viewed from the front side to the rear side. Is for limiting the amount of rotation.
In addition, the rear end portion of the rear support member 63 is formed with a hook portion 63d that is bent so as to be spaced from the lower front support member 62. The rear end of the wire spring 64 to be described later is fixed to the hanging portion 63d.

The wire spring 64 is formed in a substantially U shape when viewed from above, and is attached to the front support member 62 and the rear support member 63 in a state where the open side is directed inward in the seat width direction.
Specifically, the rear end 64 a of the wire spring 64 is fixed to the hanging portion 63 d of the rear support member 63, and the front end 64 b, which is a biasing portion, is seat width relative to the front support piece 62 b of the front support member 62. It is attached to the front support member 62 so as to wrap around inward in the seat width direction from the outer side in the direction.
The front end 64b of the wire spring 64 is bent upward in the natural state, and the front end 64b is formed below the protrusion 61i of the first lock lever 61 described above.
That is, the front end 64b of the wire spring 64 is in an upward direction, which is a direction in which the first lock lever 61 is locked, in a state where the front end 64b is pressed from above by the protruding portion 61i of the first lock lever 61. The protrusion 61i is urged.

<Control cable configuration>
Next, the first control cable 70 and the second control cable 71 related to the slide lock releasing operation will be described with reference to FIGS.
9A is a front view showing the state of the first control cable 70, the first link 60a, and the second link 65a in the slide lock state, and FIG. 9B is just after the start of the slide lock release operation. FIG. 9C is a front view showing the state of the first control cable 70, the first link 60a, and the second link 65a in FIG. 9, and FIG. 9C shows the first control cable 70, the first link 60a, and the second link 65a in the slide lock released state. It is a front view which shows the state.
10A is a plan view showing a state of the first control cable 70, the second control cable 71, the first link 60a, and the second link 65a in a slide lock state, and FIG. 10B is a slide lock. FIG. 10C is a plan view showing the state of the first control cable 70, the second control cable 71, the first link 60a, and the second link 65a immediately after the start of the release operation, and FIG. 10C shows the first control cable in the slide lock release state. 70 is a plan view showing states of the second control cable 71, the first link 60a, and the second link 65a.

  The first control cable 70 and the second control cable 71 are configured so that the slide lock can be released only by operating only one of them. For example, the operation part of the first control cable 70 is provided on the seat side, and the operation part of the second control cable 71 is provided on the rear side of the seat so that the slide lock can be released from two places. is there.

The first control cable 70 includes an inner cable 70a and an outer cable 70b that covers most of the inner cable 70a.
Similarly, the second control cable 71 includes an inner cable 71a and an outer cable 71b that covers most of the inner cable 71a. The first control cable 70 and the second control cable 71 are arranged so as to be bent in the slide lock state.

In the inner cable 70a of the first control cable 70, the engaging end portion 70c at the distal end is engaged with the retaining edge 60p of the through hole 60e, and can be pulled out from the base end portion 70e of the first control cable 70. Has been. The base end portion 70e is fixed to the upper rail 4 or a member on the upper rail 4 side.
Similarly, in the inner cable 71a of the second control cable 71, the engagement end portion 71c at the distal end is engaged with the retaining edge 65p of the through hole 65e. The base end (not shown) is fixed to the upper rail 4 or a member on the upper rail 4 side.

In the outer cable 70b of the first control cable 70, a fixed end portion 70d at the distal end is fixed to the notch 65h of the holding portion 65d of the second link 65a, and the proximal end side is the proximal end portion of the first control cable 70. It is fixed to 70e.
Similarly, in the outer cable 71b of the second control cable 71, the fixed end portion 71d at the tip is fixed to the notch 60h of the holding portion 60d of the first link 60a, and the base end side is the second control cable 71. It is fixed to a base end (not shown).

As described above, the first link 60a on the rear side of the seat has the first bent portion 60m, and the base end portion 60b is shifted from the intermediate portion 60c toward the second link 65a, which is the front side of the seat. The second link 65a on the front side of the seat has a second bent portion 65m, and the base end portion 65b is formed so as to be shifted to the first link 60a side on the rear side of the seat with respect to the intermediate portion 65c.
As described above, the first control cable 70 has the outer cable 70b fixed to the holding portion 65d at the distal end of the intermediate portion 65c in the second link 65a, and the inner cable 70a to the proximal end portion 60b in the first link 60a. Has been fixed.

The first control cable 70 has an engagement end portion 70c engaged with the retaining edge 60p of the through hole 60e on the extension in the direction in which the inner cable 70a protrudes and retracts from the outer cable 70b. As described above, when the first control cable 70 operates, the set of links 60 operate smoothly.
Further, as with the first control cable 70, the second control cable 71 is formed, so that when the second control cable 71 operates, the pair of links 60 operate smoothly.

(Control cable operation)
The first control cable 70 and the second control cable 71 are the one that operates the first link 60a is the inner cable 70a or the outer cable 71b, and the one that operates the second link 65a is the outer cable. Only the operation of the first control cable 70 will be described because there is no difference in other operations only in the difference between the cable 70b and the inner cable 71a.

  When the user operates an operation lever or the like (not shown) from the slide lock state shown in FIGS. 9 (A) and 10 (A), the inner cable 70a is moved from the first slide rail 2a to the second slide rail 2b side. When pulled in the first direction D1 shown in FIG. 9B, the first link 60a engaged with the inner cable 70a and the engagement end portion 70c moves in the first direction D1. As the first link 60a moves, the first lock lever 61 fixed to the first link 60a by the engagement pin 60k is counterclockwise in FIG. Will be rotated.

At this time, since the inner cable 70a is pulled from the base end portion 70e side of the first control cable 70, the amount of bending of the first control cable 70 is reduced. For this reason, in the outer cable 70b fixed at the base end portion 70e, a force for pressing the holding portion 65d of the second link 65a with the fixed end portion 70d is generated in the second direction D2 in FIG. Further, the reaction force of the pulling force of the inner cable 70a generates the same pressing force from the outer cable 70b in the second direction D2, and is applied from the fixed end portion 70d to the holding portion 65d of the second link 65a.
The second link 65a moves in the second direction D2 due to the load from the fixed end portion 70d applied to the holding portion 65d. As the second link 65a moves, the second lock lever 66 fixed to the second link 65a with the engagement pin 65k rotates against the urging force of the wire spring 69 in FIG. Will move.

  Further, when the user pulls the inner cable 70a from the first slide rail 2a to the second slide rail 2b side, the first link 60a moves to the second slide rail 2b side and moves to the first lock lever 61 as described above. Rotates counterclockwise. By this rotation, as shown in FIGS. 8, 9C and 10C, the lock claw 61b is extracted from the lock hole 3a to the inside of the first slide rail 2a. Furthermore, when the hook portion 61h of the first lock lever 61 comes into contact with the rotation stopper 63c, the rotation of the first lock lever 61 is stopped.

In this state, when the inner cable 70a is further pulled, the amount of bending of the first control cable 70 is reduced as described above, so that the outer cable 70b has the holding portion 65d of the second link 65a at the fixed end portion 70d. The pushing force is generated in the second direction D2 in FIG. Further, the reaction force of the pulling force of the inner cable 70a generates the same pressing force from the outer cable 70b in the second direction D2, and is applied from the fixed end portion 70d to the holding portion 65d of the second link 65a. That is, only the second link 65a moves in the second direction D2, and the second lock lever 66 rotates clockwise.
Similar to the first lock lever 61, the lock claw 66b is pulled out from the lower rail 3 by this rotation, and the hook portion 66h of the second link 65a contacts the rotation stopper 68c, whereby the second lock lever. The rotation of 66 stops.

  In other words, the second link 65a is moved by the force of the outer cable 70b extending in the seat width direction and the inner cable 70a generated in the outer cable 70b as the amount of bending of the first control cable 70 decreases. This is the reaction force of the pulling force. Therefore, the first lock levers 61 on both sides are operated by operating the inner cable 70a so that a force against the urging force of the wire spring 64 is applied, in other words, the amount of bending of the first control cable 70 is reduced. The second lock lever 66 can be rotated to release the slide lock.

  Further, since the inner cable 70a is connected to the first link 60a and the outer cable 70b is connected to the second link 65b, the force applied from the inner cable 70a and the outer cable 70b to the first link 60a and the second link 65b is It is converted into a linear change in the left-right direction of the seat and applied to the first lock lever 61 and the second lock lever 66. For this reason, the operation amount of the inner cable 70a is smaller than that in which the control cable 70 is connected to the first lock lever 61 or the second lock lever 66 without passing through the first link 60a and the second link 65b. Thus, the correlation between the change in the rotation amount of the first lock lever 61 and the second lock lever 66 is stabilized.

  Further, as shown in FIG. 9C, when the slide lock is released, the sliding pin 60j abuts against the edge of the support hole 65f, so that the first link 60a and the second link 65a are mutually connected. Therefore, the movement in the direction overlapping with is restricted. Therefore, when the inner cable 70a is further pulled in the slide lock state, the load is concentrated between the rotation stopper 63c and the hook portion 61h, or the load is applied between the rotation stopper 68c and the hook portion 66h. It is possible to prevent the load from being concentrated by dispersing the load on the sliding pin 60j that contacts the edge of the support hole 65f.

  Further, as shown in FIG. 10, depending on the operation of the first control cable 70, the relative positional relationship between the inner cable 71a and the outer cable 71b in the second control cable 71 does not change. In particular, when the second control cable 71 is not operated by the user, the retaining edge 65p of the through hole 65e of the second link 65a does not engage with the engagement end portion 70c of the second control cable 71. As shown in FIG. 9, the through hole 65e is formed sufficiently long on the second slide rail 2b side. The through hole 60e of the first link 60a is also formed sufficiently long on the first slide rail 2a side for the same reason.

  When the force pulling the inner cable 70a is released, the first link 60a and the second link 65a are moved by the restoring force of the tension coil spring 8, and the restoring force of the wire springs 64 and 69 is applied. The first lock lever 61 and the second lock lever 66 are rotated to return to the initial state of FIG. In addition, this invention is not limited to the structure provided with the tension coil spring 8, For example, it is made to urge | bias in the direction where the 1st link 60a and the 2nd link 65a overlap using elastic materials, such as a rubber string and elastomer resin. Also good.

  Further, as described above, in the vehicle seat slide device 1 according to the present embodiment, the first link 60a is formed with the first bent portion 60m, and the second link 65a is formed with the second bent portion 65m. ing. By forming the first bent portion 60m and the second bent portion 65m as described above, the first link 60a and the second link 65a can be smoothly moved by the operation using the first control cable 70 or the second control cable 71. Will be.

  With reference to FIG. 11, this effect is demonstrated on behalf of the structure regarding the 1st bending part 60m and the 1st control cable 70. FIG. 11A is a plan view showing a state where the inner cable 70a is engaged with the first link 60a having the first bent portion 60m, and FIG. 11B has the first bent portion 60m. It is a top view which shows the state which engaged the inner cable 70a with the 1st link 60a which is not.

The holding portion 65d of the second link 65a to which the outer cable 70b is fixed protrudes forward from the intermediate portion 65c. As shown in FIG. 11A, the base end portion 60b having the fastening edge 60p for fastening the inner cable 70a is located on the front side of the intermediate portion 60c when the first link 60a has the first bent portion 60m. ing.
On the other hand, when the first link 60a shown in FIG. 11B does not have the first bent portion 60m, the base end portion 60b having the retaining edge 60p for fastening the inner cable 70a is the same in the front and rear as the intermediate portion 60c. Arrangement.
Thus, when the base end portion 60b is arranged, the inner cable 70a extending from the holding portion 65d to the base end portion 60b is bent relatively greatly when the first bent portion 60m is not provided. . And when the inner cable 70a contacts the inner edge of the outer cable 70b, a frictional force is generated when the inner cable 70a and the outer cable 70b move relative to each other. For this reason, the smooth operation of the first link 60a and the second link 65a operated by the inner cable 70a and the outer cable 70b is hindered.
On the other hand, when the first bent portion 60m is formed in the first link 60a, the base end portion 60b is perpendicular to the holding portion 65d by the first bent portion 60m, and the inner cable 70a is the outer cable. It will be arrange | positioned in the position along the direction extended from 70 d of fixed ends which are the front-end | tip parts of 70b. For this reason, the bending of the inner cable 70a extending from the holding portion 65d to the base end portion 60b is reduced. Therefore, the frictional force generated when the inner cable 70a and the outer cable 70b move relative to each other is suppressed, the load from the inner cable 70a is efficiently transmitted to the first link 60a, and the first link 60a and the second link 65a are smooth. Will work.
Further, in the case of the first link 60a in which the first bent portion 60m according to the above embodiment is formed, the link 60a is provided by effectively using the space on the second link 65a side where the first control cable 70 is disposed. Can do. Therefore, the space occupied by the vehicle seat slide device 1 can be reduced. Further, as shown in FIG. 10, the positions of the first lock lever 61 and the second lock lever 66 in the front-rear direction of the seat can be made equal, and a lock hole that engages with the first lock lever 61 and the second lock lever 66. Since the lower rail 3 having 3a can be formed symmetrically, manufacturing and inspection of the finished product are facilitated.

Next, the 1st link 60a provided with the 3rd bending part 60s which concerns on a modification is demonstrated with reference to FIG. Here, FIG. 12 is a plan view showing a state in which the inner cable 70a is engaged with the first link 60a having the third bent portion 60s according to the modification.
The third bent portion 60s is a portion that forms a boundary surface between the base end portion 60b and the intermediate portion 60c, and is a portion that connects the two in a bent state.
The base end portion 60b is inclined by the third bent portion 60s along the direction perpendicular to the holding portion 65d and the inner cable 70a extending from the fixed end portion 70d that is the distal end portion of the outer cable 70b. Yes. That is, the base end portion 60b is inclined with an inclination closer to the direction than the intermediate portion 60c.
In this manner, the base end portion 60b is inclined by the third bent portion 60s, so that the inner cable 70a is engaged with the extension of the intermediate portion 60c shown in FIG. The bending of 70a can be suppressed. Therefore, the smooth operation of the 1st link 60a and the 2nd link 65a is realizable like the above.

In the present embodiment, the vehicle seat slide device according to the present invention has been mainly described.
However, said embodiment is only an example for making an understanding of this invention easy, and does not limit this invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents.

  For example, in the present embodiment, the front support member and the rear support member that support the first lock lever or the second lock lever have been described as separate bodies, but may be formed integrally. Good.
