[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric slide seat used for a seat of an automobile and a lock device used therefor.
[0002]
[Prior art]
[Patent Document 1] Japanese Utility Model Laid-Open No. 5-1565
[Patent Document 2] Japanese Patent Laid-Open No. 10-138803
[0003]
In Patent Document 1, as shown in FIG. 6, a fixed rail 102 fixed to a vehicle body 101, a movable rail 104 fixed to a seat 103, and one of the rails (here, a fixed rail) can be freely rotated. There is disclosed a power seat slide device 100 including a screw member 105 that is attached and driven by power, and a nut member 106 that is detachably attached to the other rail (movable rail in this case) by an engagement / disengagement member 106a. . In this case, when the screw member 105 is rotated with the nut member 106 engaged with the other rail, the seat 103 can be moved back and forth by power. When the engagement / disengagement member 106a is further operated to disengage the nut member 106 from the other rail, the seat can be manually moved back and forth.
[0004]
As shown in FIG. 7, the power slide device disclosed in Patent Document 2 forms a nut portion (engagement hole row) 109 along a fixed rail 108 fixed to the vehicle body side, and is driven by a motor. 110 is attached to the seat 111 side so as to be rotatable about an axis extending in the front-rear direction so as to mesh with the nut portion 109. In this case, when the worm gear 110 rotates, the sheet can be moved in the axial direction by a screw action.
[0005]
[Problems to be solved by the invention]
The power seat slide device of Patent Document 1 converts a rotational motion into a straight motion by a screw mechanism including a screw member 105 and a nut member 106. Further, the device of Patent Document 2 also converts the rotation of the worm gear 110 into the movement in the axial direction by a screw action caused by the engagement between the worm gear 110 and the nut portion 109. Therefore, in any conventional technique, the screw mechanism can provide a speed reduction action, and the motor-side speed reducer can be reduced in size. Further, since the screw mechanism itself has a self-restraining action, there is an advantage that a separate locking mechanism is not required. However, since the screw mechanism is employed, back and forth backlash of the seat is likely to occur, and since the screw and the nut are always meshed, it is difficult to manually move the seat side.
[0006]
In the case of Patent Document 1, an engaging / disengaging member 106a for removing the nut member 106 from the other rail is employed so that a quick walk-in operation can be performed. However, such an engaging / disengaging member 106a is convenient for a temporary walk-in operation. However, in order to adjust the front / rear position of the seat, the seat is returned to the original position and the nut member 106 is fixed to the original position. In this state, it is necessary to move the motor back and forth by driving the motor. Therefore, handling is inconvenient. Also, the operation method is significantly different from a normal manual slide adjustment mechanism in which the seat is shifted while manually operating the lock release lever and the lock release lever is released and locked at an appropriate position. Therefore, it is difficult for an unfamiliar user to operate.
[0007]
An object of the present invention is to provide an electric slide seat that can be compatible with conventional manual seat position adjustment. Furthermore, it is a technical object of the present invention to provide an electric slide seat that can be easily switched between manual operation and electric operation. Furthermore, this invention makes it the technical subject to provide the locking device used for such an electric slide seat.
[0008]
[Means for Solving the Problems]
An electric slide seat of the present invention (Claim 1) includes a pair of left and right rails extending front and rear, a seat provided movably along the rails, and a motor-driven slide drive device that drives the seat back and forth. The slide drive device is engaged with a motor attached to the seat and a pair of left and right drums driven to rotate by the motor, and the left drum is wound around and wound in opposite directions, The forward and backward cables extending in the front and rear directions of the rail through the direction changing member provided at the left end portion of the seat and the end portion being locked to the rail or its vicinity, and the right drum And are wound in opposite directions, and each is connected via a direction changing member provided at the left end of the sheet. A forward cable and a backward cable are provided which extend in the front and rear directions of the rail and whose ends are locked to the rail or the vicinity thereof.
[0009]
In such an electric slide seat, a pair of gears that mesh with each other is provided on the pair of left and right drums, and the motor is preferably configured to drive the gears of any one of the drums (claims). Item 2). Further, it is preferable that a clutch for turning on and off the power transmission is interposed between the motor and the drum. Further, it is preferable to include a locking means for restraining / releasing the front / rear movement of the seat by remote control.
[0010]
A locking device according to the present invention (Claim 5) is a locking device that is attached to a seat that is movably provided along a pair of left and right rails extending in the front-rear direction, and that restrains / releases the movement of the seat. A lock member provided on the seat so as to operate between a plurality of lock engaging portions arranged along one rail and a lock position engaging with the lock engaging portions and an unlocking position not engaging with the lock engaging portions; And a means for constantly urging the lock member toward the lock position, and a lock release actuator provided on the back side of the seat for moving the lock member to the lock release position by electric drive. Yes.
[0011]
In such a locking device, the unlocking actuator includes a drum driven by a motor, one end locked to the drum, wound around the drum, and the other end locked to the lock member, It is preferable to include a lock release cable for operating the lock member to the unlock position by a pulling operation.
[0012]
Further, a series of lock engaging portions are arranged along the left and right rails, respectively, and left and right lock members that engage with the respective lock engaging portions are provided, and one end of two cables is provided on the drum. It is more preferable to have a lock release cable that is locked and wound in the same direction, and whose other ends are locked to the left and right lock members.
[0013]
[Operation and effect of the invention]
When the drum rotates in one direction, the electric slide sheet of the present invention (winding), for example, winds up the left and right forward cables around the drum and feeds the backward cable from the drum. Thereby, the length of the cable between the direction change member and the end of the cable for advancement is shortened. For this reason, the seat acts so as to draw a cable for advancement extending toward the vicinity of the front end of the rail, and advances along the rail. On the other hand, since the reverse cable is sent out, the forward movement of the seat is not hindered. When the motor rotates in the reverse direction and the drum rotates in the reverse direction, the left and right retraction cables are wound around the drum and the advance cable is sent out. As a result, the seat moves backward.
[0014]
As described above, in the electric slide sheet of the present invention, the rotational motion is converted into the linear reciprocating motion by winding and feeding the cable wound around the drum without using the screw mechanism. Therefore, unless a transmission having a self-restraining action such as a worm gear transmission is used, the seat can be manually moved back and forth. In order to fix the moved sheet to the position, the lock mechanism of the conventional manually operated sheet position adjusting device can be used as it is. Alternatively, an electric type locking device described later may be used.
[0015]
When the pair of left and right drums are provided with a pair of gears that mesh with each other, and the motor is configured to drive the gears of one of the drums (Claim 2), the left and right drums are accurately The cable is wound up and sent out in synchronization. Therefore, the forward and backward movement of the seat is smooth.
[0016]
When a clutch for turning on and off of power transmission is interposed between the motor and the drum (Claim 3), since the motor and the speed reducer do not become resistance during manual operation, the motor and the drum can be operated smoothly. . Even when a speed reducer having a self-restraining action such as a worm speed reducer is employed, the seat position can be manually adjusted.
[0017]
In an electric slide seat provided with a lock means for restraining / releasing the movement of the seat by remote operation, after the seat position is adjusted by electric drive, the forward / backward movement of the seat is restrained by the remote operation lock means. Can do. Therefore, it is possible to easily stabilize the sheet without play as compared with the case of locking with a manual lever or the like. When the seat is moved back and forth, the lock means may be released. In addition, when the locking / releasing switching of the locking means is electrically driven, a series of operations from unlocking to the back-and-forth movement of the seat and re-locking can be easily automated.
[0018]
In the lock device of the present invention (Claim 5), in a state where the unlocking actuator is not operated, the lock member is biased to the lock position by the biasing means, and the lock member is locked to the lock locking portion. Thereby, the back and forth movement of the seat is restricted. When the lock release actuator is operated, the lock member moves to the lock release position against the urging force of the urging means, so that the engagement with the lock engaging portion is released, and the seat can be moved back and forth. Accordingly, the seat can be moved back and forth by electric operation or manual operation.
[0019]
The unlocking actuator includes a drum driven by a motor, one end locked to the drum, wound around the drum, and the other end locked to the lock member, and the lock member is unlocked by a pulling operation. When the cable is provided with an unlocking cable for operating to the position (Claim 6), when the motor is rotated and the cable is wound by the drum, the locking member is pulled to the unlocking position via the cable. . Thereby, the lock is released. When the drum is rotated in the reverse direction, the pulling operation force by the cable is weakened, the lock member is moved to the lock position by the urging means, and the movement of the sheet is locked. Thus, when operating a lock member via a cable, a manual unlocking lever etc. can be operated with a cable, In that case, manual operation and automatic operation can be made compatible.
[0020]
Further, a plurality of left and right lock locking portions are arranged along the left and right rails, and left and right lock members that engage with the respective lock locking portions are provided, and two cables are provided on the drum. In the case where the cable is provided with an unlocking cable in which one end of each is locked and wound in the same direction, and each other end is locked to the left and right locking members (Claim 7), the seat is placed near the left and right rails. Since it can restrain, a sheet | seat can be fixed still more stably.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic plan view showing an embodiment of the electric slide seat of the present invention, FIG. 2 is a plan view of a main part showing an actuator portion of the electric slide seat, and FIG. 3A is a plan view showing a rail portion of the electric slide seat. 3b is a cross-sectional view taken along the line III-III in FIG. 3a, FIG. 4 is a front view of the main part of the electric slide seat, and FIG. 5 is a perspective view of the main part showing the lock mechanism of the electric slide sheet.
[0022]
An electric slide seat 10 shown in FIG. 1 includes a pair of left and right rails 11 attached to a vehicle body, a seat 12 movably provided on the rails, and a slide drive device 13 for driving the seat back and forth along the rails. And a lock mechanism 14 for fixing the seat to a desired position of the rail 11.
[0023]
For example, as shown in FIG. 4, the rail 11 is an elongated material having a guide groove 11a formed on the upper surface, and a known rail such as a metal plate bent is used. On the bottom surface of the rail 11, a locking hole row 11b in which the claw 42 of the locking member 40 shown in FIG. 3B is locked is arranged so as to extend in the longitudinal direction. Such a rail 11 is usually installed obliquely so that the front side is somewhat higher than the rear side.
[0024]
As shown in FIGS. 3a, 3b, and 4, the sheet 12 is attached to a box-shaped support base 12a divided into left and right, a plate 12b mounted on the left and right support bases 12a, and an upper surface thereof. And a cushion (not shown). The rails 11 and the seats 12 may be the same as those used in a conventional position adjustment mechanism for a front seat of a conventional automobile or a second to third row seat.
[0025]
The slide drive device 13 includes a slide actuator 15 attached to the back surface of the plate 12b of the seat 12, left and right forward cables 16 that are pulled and fed by the actuator, and the forward cables alternately. A retraction cable 17 that is pulled and sent out, and pulleys 18 and 19 that are attached to the four corners of the back surface of the plate 12b of the seat 12 and change the direction of the forward cable 16 and the reverse cable 17 are provided. Yes. Both the cables 16 and 17 are guided between the sliding actuator 15 and the pulleys 18 and 19 by flexible conduits 20 and 21. As the cables 16 and 17 and the conduits 20 and 21, those similar to the inner cable and the conduit for the pull control cable used in the window regulator or the like can be used.
[0026]
As shown in FIG. 2, the actuator 15 is connected to a housing 24, a motor M1 attached to the housing, a worm reduction gear G1 connected to the output shaft of the motor, and an output side of the worm reduction gear G1. Electromagnetic clutch C, a small first gear 25 connected to the output side of the electromagnetic clutch, a large second gear 26 meshing with the first gear 25, and a small diameter co-rotating with the second gear. , A large-diameter left drum gear 28 that meshes with the drive gear, and a right drum gear 29 that meshes with the left drum gear. Each gear is supported by the housing 24 so as to be rotatable about an axis substantially perpendicular to the seat 12.
.
[0027]
The left drum gear 28 and the right drum gear 29 have the same number of teeth, and rotate at the same rotational speed in opposite directions. The left drum gear 28 and the right drum gear 29 are connected to a left drum 30 and a right drum 31 for winding the cable, respectively. The left drum 30 is engaged with the end of the left forward cable 16 and wound in the counterclockwise direction in FIG. 2 and extends to the left in FIG. Further, the advance cable 16 is guided to the pulley 18 on the front side (upper side in FIG. 1) of FIG. 1 by the conduit 20 as described above, and is redirected forward by the pulley 18 and then to the front end of the rail 11. It is locked.
[0028]
Further, the left drum 30 is engaged with the end portion of the cable for backward movement 17 on the left side, wound clockwise in FIG. 2, and extends to the left side in FIG. Further, as described above, the reverse cable 17 is guided by the conduit 21 to the pulley 19 at the rear end (lower side in FIG. 1) of FIG. Locked to the end. Normally, the left drum 30 is provided with a spiral guide groove for guiding the forward cable 16 and the backward cable 17, but this guide groove may also serve as a groove for both cables (see FIG. 4). ). That is, when the seat 12 is moving forward, a lot of the cable 16 for forward movement is wound up, but the cable for backward movement is sent out by that amount, so the substantial length of the groove around which the cable is wound does not change. is there. By doing in this way, the thickness of the drums 30 and 31 can be made thin.
[0029]
The relationship between the right drum 31 and the right advance cable 16 and the reverse cable 17 and the relationship between the cables 16, 17 and the right pulleys 18, 19 and the right rail 11 are as follows. Substantially the same with only line symmetry.
[0030]
As shown in FIG. 3a, the pulleys 18 and 19 are rotatably attached to the bracket 32 by a shaft. The bracket 32 is attached to the support base 12a of the sheet 12 or the slider 33 supporting the same with screws or the like. The bracket 32 preferably serves also as a pulley cover. The pulleys 18 and 19 may be directly attached to the support base 12a so as to be rotatable without using the bracket 32. Instead of the pulley, a slide guide (see reference numeral 44 in FIG. 5) having an arcuate guide groove may be used.
[0031]
As shown in FIGS. 3a and 3b, the slider 33 is made of a metal plate or the like, and its lower part is inserted into a guide groove 11a on the upper surface of the rail 11 as shown in FIG. Normally, the lower portion of the slider 33 extends to the left and right, thereby preventing the slider 33 from slipping out. The support base 12 a is attached to the slider 33 by bolts and nuts welded to the slider 33. Further, a roller that rolls on the upper surface of the rail 11 is attached to the slider 33 (see reference numeral 33a in FIG. 4). As such a slider 33, a slider that is used in a conventionally known manual seat longitudinal adjustment mechanism can be used.
[0032]
In the slide drive device 13 configured as described above, when the motor M1 of the actuator 15 rotates, the worm gear of the speed reducer G1 rotates, and the worm wheel engaged therewith is decelerated and rotated. C is transmitted to the input side. When the electromagnetic clutch C is on, the first gear 25 rotates in the direction of the arrow P1, for example, through the output side of the electromagnetic clutch C. As a result, the second gear 26 meshing with the first gear 25 rotates in the direction of the arrow P2. Accordingly, the drive gear 27 integral with the second gear 26 rotates in the direction of the arrow P2, and the left drum gear 28 rotates in the direction of the arrow P3.
[0033]
As a result, the right drum gear 29 meshing with the left drum gear rotates in the direction of arrow P4. Therefore, the left drum 30 and the right drum 31 rotate at the same rotational speed in the opposite directions. As the left and right drums 30 and 31 rotate, the left and right forward cables 16 are wound around the drums 30 and 31, and the backward cable 17 is sent out from the drums. As a result, the sheet 12 advances in the direction of arrow F in FIG.
[0034]
When the motor M1 is rotated in the reverse direction, the left and right drums 30 and 31 rotate in the reverse direction (the reverse direction to the arrow P3 and the reverse direction to the arrow P4), respectively. Is wound up, and the cable 16 for advance is sent out. As a result, the sheet 12 moves backward in the direction of arrow R in FIG.
[0035]
The electromagnetic clutch C is kept in the “ON” state when moving forward and backward by normal motor driving as described above. Thereby, the rotation of the motor M1 is transmitted to the drums 30 and 31 side. When operating manually, when the electromagnetic clutch C is “disengaged”, the torque transmission between the motor M1 and the reduction gear G and the drums 30 and 31 is cut off, so that the seat 12 can be easily moved back and forth manually. it can. As a result, even if the worm speed reducer G1 having self-restraint property is used as the speed reducer G1, it can be switched to manual operation. In the case of using a speed reducer using a spur gear or the like that does not have a self-restraining action, it is not always necessary to interpose the electromagnetic clutch C. However, even in that case, the electromagnetic clutch C is interposed so that the resistance of the motor M1 and the speed reducer is eliminated, so that manual operation becomes easier. When the seat 12 is moved back and forth manually, the forward cable 16 and the backward cable 17 are wound around the corresponding drums 30 and 31, respectively, and sent out, but this does not hinder manual operation.
[0036]
The actuator 15 uses a pair of left and right drums 30 and 31 and winds a forward cable and a backward cable on one side around each drum. Therefore, the thickness of each of the drums 30 and 31 can be reduced as compared with the case where the four cables are wound around one drum. Further, as described above, the guide grooves of the cables of the drums 30 and 31 are used both for forward movement and for backward movement. Therefore, even if it is provided on the back surface of the sheet 12, the actuator 15 does not protrude greatly, and interference with the floor surface or the like can be avoided. However, the four cables may be wound / delivered with one drum. In that case, it is preferable to increase the diameter of the drum because the thickness can be reduced.
[0037]
Next, returning to FIG. 1, the lock mechanism 14 will be described. The lock mechanism 14 includes a locking portion 34 that directly restrains the movement of the seat 12 with respect to the rail 11, a locking actuator 35 that operates the locking portion, and a lock-release cable 36 that connects them. As shown in FIG. 3 b, the locking portion 34 is moved up and down by a lever 38 that is rotatably attached to the slider 33 by a pin 37, a spring 39 that constantly biases the lever clockwise, and the lever 38. And a lock member 40 to be moved. An engaging pin 40 a protrudes from the lock member 40, and the engaging pin engages with a long hole 38 a formed in the lever 38. Thereby, the rotation of the lever 38 can be smoothly converted into the vertical movement of the lock member 40.
[0038]
As the spring 39, a torsion coil spring wound around a pin 37 supporting the lever 38 is employed. However, other springs such as a tension coil spring may be used. The lock member 40 is guided by a recess 41 formed in the slider 33 so as to be movable up and down. Three claws 42 are formed at the lower end of the lock member 40, and these claws 42 are engaged / disengaged with the locking hole row 11 b formed at the bottom of the rail 11. As the lock member 40 and the locking hole row 11b, a conventional manual seat position adjusting mechanism can be used.
[0039]
The end portion of the unlocking cable 36 is engaged with the end portion of the lever 38 on the side where the claw 42 is present. As shown in FIG. 5, a conventionally known cable end fitting is fixed to the end of the cable 36 by caulking or the like, and a U-shaped notch or groove 43 through which the cable 36 passes is formed at the end of the lever 38. Has been. The cable 36 extends upward, is redirected by a direction-changing slide guide 44 (see FIG. 5), and is guided by the conduit 45 to the aforementioned unlocking actuator 35. As described above, since the end of the cable 36 is only locked in the groove 43 by the cable end fitting 36a, the lever 38 can be rotated counterclockwise when the cable 36 is pulled upward, Conversely, when the lever 38 is rotated counterclockwise by manual operation, the cable 36 is not affected.
[0040]
A contact piece 46 is formed at the other end of the lever 38 so as to contact the contact portion 48 of the manual operation lever 47. As the manual operation lever 47, a conventional lever for adjusting the sheet position by manual operation can be used. Note that an operation cable 49 is connected to the contact portion of the manual operation lever 47 for performing unlocking operation by remote operation from a rear seat or the like. Reference numeral LS1 in FIG. 3b is a limit switch for confirming unlocking.
[0041]
As shown in FIG. 2, the unlocking actuator 35 is connected to a housing 50, a motor M2 attached to the housing, a worm reducer G2 connected to the motor, and an output shaft of the worm reducer. The drum 51 is provided. One end of a cable 36 that unlocks the left and right lock members 40 is engaged with the drum 51, wound in the same direction, and extends to the left and right conduits 45. Since the stroke of the unlocking operation is small, the thickness of the drum 51 does not increase so much even if a configuration in which two cables 36 are wound around one drum is adopted. However, if necessary, left and right drums can be provided in the same manner as the actuator 15 of the slide drive device 13. Further, a speed reducer other than the worm speed reducer can be adopted as the speed reducer.
[0042]
In the lock mechanism 14 configured as described above, the lever 38 for operating the lock member 40 is constantly urged clockwise by the spring 39 in FIG. Yes. Therefore, the claw 42 is fitted into any one of the locking hole rows 11b of the rail 11 and has a locking action. Thereby, the seat 12 does not move back and forth. When the seat position is automatically adjusted, the motor M2 of the actuator 35 rotates in one direction, the drum 51 rotates in the clockwise direction in FIG. 2, and the unlocking cables 36 on both the left and right sides are wound up. As a result, the lever 38 rotates counterclockwise against the urging force of the spring 39 and lifts the lock member 40. Thereby, the claw 42 is extracted from the locking hole, and the lock is released. In this state, the above-described slide drive device 13 operates to move the seat 12 forward or backward to adjust the position.
[0043]
When the position adjustment is completed, the motor M2 of the actuator 35 rotates in the reverse direction, the drum 51 rotates in the counterclockwise direction, and the cable 36 for unlocking is sent out. As a result, the lever 38 is rotated clockwise by the urging force of the spring 39, the lock member 40 is moved downward, and the claw 42 is again fitted into the locking hole. Thereby, the sheet 12 is fixed at the adjusted position.
[0044]
When the user gets on and off the vehicle, the seat 12 needs to be quickly retracted. In this case, the manual operation lever 47 is operated to be pulled up. As a result, the unlocking lever 38 rotates counterclockwise against the biasing force of the spring 39, pulls up the locking member 40, and the lock is released. At this time, the cable end fitting 36a of the cable 36 for unlocking remains on the lower side as described above, so that it does not interfere with the rotation of the lever 38. Then, the limit switch LS1 detects that the lever 38 is rotated, and the electromagnetic clutch of the slide driving actuator is set to “disengagement”. Therefore, the user can manually move the seat 12 back and forth freely. When the manual operation lever 47 is released after being moved to a desired position, the lever 38 is rotated clockwise by the urging force of the spring 39, and the locking action is performed again, and the electromagnetic clutch C is "on". . After the user gets on and off, the manual operation lever 47 can be operated again as described above to move the seat 12 back and forth, or the seat can be moved back and forth automatically.
