Description

A walk-in memory apparatus for seat of car,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a memory device that is a walk-in car seat, and more particularly, to a memory device that is a walk of an automobile seat that is movable to a position set by a user when the seat is moved backward after a walk- .

Generally, the seat of a vehicle is designed so that the occupant can adjust the angle of the seat back and front position in accordance with his / her physical condition.

In the case where the seat is on the ascending / descending moving line to the rear seat, like the passenger seat of the three-door vehicle or the sliding door side seat of the van-type vehicle, Is installed.

In addition, a walk-in memory function is implemented so that the seat can be stopped at an appropriate position when the seat moved backward after the passenger w / o departs forwards.

One example of a memory device that is a work-in-memory device according to the related art is disclosed in Korean Patent Laid-Open Publication No. 10-2010-0010705 (Hyundai Motor Company, et al.

As shown in FIG. 1, the conventional walk-in memory device includes an unlocking portion 120 pulled by a cable 114 when the seatback is folded, an unlocking portion 120 which is rotated downward by the unlocking portion 120, A latch plate 150 for holding the track lock plate 140 in the locked state by restricting the locking portion 130 and a latch plate 150 for pressing the lock plate 130, A reference stopper 30 provided at an appropriate position of the floor of the vehicle body (a position where the seat is moved rearward enough to allow the occupant to sit) in consideration of the amount of movement, and a reference stopper 30 riding over the reference stopper 30 when the seat moves from the front to the rear, And a stopper bracket 160 for releasing the locking state of the latching plate 130 of the latch plate 150.

Accordingly, during the work-in operation, the locking portion 130 pushes the track lock plate 140 downward to release the engagement between the track lock plate 140 and the lock guide 21, so that the seat can be moved forward.

When the seat is moved backward after the passenger gets in or out of the passenger compartment, the stopper bracket 160 moves upward through the reference stopper 30 to lift the latch plate 150, The locking portion 130 does not push the track lock plate 140 by releasing the restricting state of the track lock plate 140 and the track lock plate 140 is again engaged with the lock guide 21 to fix or stop the seat.

As described above, the reference stopper 30 is provided at an appropriate position on the sheet movement path. When the sheet passes the reference stopper 30 when the sheet is moved backward after the operation as a workpiece, the sheet is automatically fixed, It is inconvenient to push the seat back while the sliding lever (the lever provided at the lower part of the seat cushion, which is used when the occupant sits on the seat and adjusts the position through the usual forward / backward sliding) Is solved. That is, a memory function, which is a walk that allows the seat to be moved and fixed to a proper position when the seat is moved backward after the operation as a workpiece, is performed.

However, in the above-mentioned conventional walk-in memory device, since the reference stopper 30 is fixed to the floor of the vehicle body, the seat can always be stopped at a constant position (position past the reference stopper 30)

That is, since the seat can not return to the position set by the user (e.g., the position adjusted by the previous occupant) after the seat is walked, the seat is always stopped only at the position past the reference stopper 30. Therefore, .

Further, the conventional walk-in memory device occupies a large installation space as a whole because a large number of parts are installed in the seat cushion frame and operate in the external space of the seat track. This increases the height of the seat on the layout, and thus increases the height of the entire body of the vehicle. This has not been addressed in recent development trends that make up the entire body of the vehicle low.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a sheet returning position in which a sheet returning position can be set at an arbitrary position on a sheet forward / backward movement path, Which is a work of a car seat in which a post-operation seat can be stopped and fixed at a position set by a user.

Further, according to the present invention, the components constituting the apparatus are provided inside the lower rail (fixed rail) and the upper rail (moving rail) constituting the seat track, so that the structure around the seat cushion frame and the seat track is simplified, So that it is possible to help lower the car body by not affecting the car body.

According to an aspect of the present invention, there is provided a railway tracker comprising: a guide rail fixed to a lower rail; a base member installed to be movable forward and backward on the guide rail; A mounting bracket fixed to the inner side of the upper rail; a memory lever mounted on the mounting frame so as to be movable up and down to operate the latch bracket; Or releasing the set plate.

A plurality of locking grooves are formed in the guide rail, and a locking end is inserted into the locking bracket to be inserted into the locking groove.

Both side ends of the guide rails are bent upwardly in the form of wrapping both side ends of the base member.

A through hole is formed in the latch bracket, an insertion end is inserted into the through hole at the lower end of the memory lever, and a latching jaw is formed at both sides of the insertion end of the memory lever.

A memory lever hole through which the memory lever can pass is formed in the upper plate and the lower plate of the mounting frame.

And a lock lever is installed on the rotary shaft in the inner space of the mounting frame, and the memory lever is connected to the lock lever by a connecting pin So that the memory lever is moved upward by the lock lever during the walk-in operation.

A link lever is provided on the pivot shaft, a wire hole is formed in the link lever, and a wire pulled in a work-in operation is connected to the wire hole.

The wire holes are laterally expanded and formed so that the connecting portions of the wires can move inside.

And a torsion spring for fixing the memory lever to the memory lever and moving the memory lever downward is provided at one end of the mounting frame.

The set plate is fixed to the lower plate of the mounting frame by a fixing pin and the fixing pin hole of the set plate through which the fixing pin passes is extended and formed in the moving direction of the sheet so that the set plate can be moved forward and backward with respect to the mounting frame. .

And an engaging step is formed at one end of the set plate to engage with a base member fixed at a predetermined position when the work is moved back and forth.

And a compression spring is installed on the spring mounting portion. One end of the compression spring is supported on one side of the mounting frame and the other end is supported on a spring pin fixed to the spring mounting portion, So that the compression spring exerts a force to move the set plate backward.

A coupling groove is formed on one side of the memory lever, and a coupling end inserted into the coupling groove is formed in the set plate.

A memory lever groove into which a memory lever is inserted is formed on one side of the set plate, and a front side end of the memory lever groove serves as the coupling end.

According to the present invention as described above, the user can freely set the return position of the seat back to the work. That is, it is possible to use a work memory, a user memory.

After the work is done, the seat is accurately stopped and fixed at the position set by the user when the seat is returned to the rear. Therefore, the trouble of readjusting the position of the seat after the seat is returned to the back is solved.

The walk-in memory device is provided inside the seat track, and the configuration of the periphery of the seat cushion frame and the seat track becomes very simple.

Since the walk-in memory device is installed in the space in which the seat track is empty, the height of the seat is not increased. Therefore, the overall layout of the vehicle body can be made low.

Further, since the impact generated when the seat moves backward is blocked by the set plate and is not transmitted to the memory lever, no high load acts on the memory lever even when the user moves the seat with excessive force. Therefore, since the memory lever is not deformed or broken, the failure of the apparatus does not occur well, and the stability and reliability of operation are improved.

FIGS. 4 to 11 illustrate shapes of major components of the present invention, and the shapes of the components, as well as their mutual relationship, will be described with reference to FIGS. 2 and 3. FIG.

As shown in FIG. 4, the guide rail 40 has a cross-sectional shape in which both ends of a flat bottom surface are rounded upward, and a plurality of locking grooves 41 are formed at one side of the semi-

The guide rail 40 is fixed to the inner bottom surface of the lower rail 10 and is longitudinally mounted along the center line of the lower rail 10. [ The guide rail 40 is fixed to the vehicle body and does not move since it is fixed to the bottom surface of the vehicle body by the lower rail 10. [

The semicircular end portions on both sides of the guide rail 40 cover both side ends of the base member 50 to prevent the base member 50 inserted in the inner space of the guide rail 40 from being separated from the upper side of the guide rail 40 give.

As shown in Fig. 5, the base member 50 is formed with semicircular protrusions 51 on both sides in the longitudinal direction (the same direction as the back and forth movement in the state of being inserted into the guide rail 40). The space between the both side projecting portions 51 is used as the latch bracket installation space 52.

A circular pinhole (53) is formed through the both side projecting portions (51).

6, the latch bracket 60 is in the form of a rectangular plate having a size that can be inserted into the latch bracket installation space 52 of the base member 50, and one central portion of the body is bent downward So that a locking end portion 61 is formed.

The locking end portion (61) has a width that can be inserted into the locking groove (41) of the guide rail (40).

A through hole 62 is formed in the middle of the latch bracket 60 in the longitudinal direction (vertical direction in the figure) on the same line as the locking end portion 61. The through hole 62 is eccentrically formed on the opposite side where the locking end portion 61 is formed. The through hole 62 is formed to have a width at which the insertion end 83 formed at the lower end of the memory lever 80 can be inserted.

The base member 50 and the latch bracket 60 are coupled to each other via a coupling pin 63 having a circular cross section. The engaging pins 63 are installed in such a manner that both ends of the engaging pins 63 are inserted into the pin holes 53 formed in the protrusions 51 on both sides of the base member 50. The latch brackets 60 ). The engagement pin 63 and the latch bracket 60 are integrally welded together or fastened together with bolts or the like so that they can not be mutually movable. The coupling pin 63 is freely rotatable in the pin hole 53. The latch bracket 60 is rotatable about the coupling pin 63 with respect to the base member 50. [

The latch bracket 60 tends to rotate in the direction in which the locking end portion 61 is formed at all times because the portion where the locking end portion 61 is formed on both left and right sides around the coupling pin 63 is heavy. Although not shown, a torsion spring is provided on the coupling pin 63, and both ends of the torsion spring are fixed to the bottom surface of the base member 50 and the side surface of the latch bracket 60, respectively. By the elastic force of the torsion spring, It is preferable to rotate the engaging pin 60 more reliably about the engaging pin 63 toward the locking end 61 side (counterclockwise direction).

As shown in Fig. 7, the mounting frame 70 is a part having a hexagonal section, and memory lever holes 71a and 71b are formed in the upper and lower plates, respectively, in the longitudinal middle portion. The memory lever holes 71a and 71b are formed such that the centers of the memory lever holes 80 are aligned so as to be vertically movable in the vertical direction and the memory lever holes 71a of the bottom plate are aligned with the shape of the memory lever 80 And is narrower than the memory lever hole 71b of the top plate.

3, the spring fixing hole 73 is formed such that the spring fixing plate 150 is installed between the upper plate and the lower plate of the mounting frame 70 because the coil length (axial length) of the torsion spring 140 is short It may be formed at a corresponding position of the spring fixing plate 150. That is, when the spring fixing plate 150 having the spring fixing hole is provided, the spring fixing hole 73 need not be formed on the side plate of the mounting frame 70.

Fixing pinholes 74a and 74b are formed on both sides in the longitudinal direction of the lower plate of the mounting frame 70.

Fixing pins 131a and 131b are fixedly inserted into the fixing pin holes 74a and 74b and the set plate 90 is fixed to the mounting frame 70 by the fixing pins 131a and 131b.

The upper and lower plates of the mounting frame 70 may be formed with spring fixing plate holes 75a and 75b so that the spring fixing plate 150 may be inserted and then welded and fixed. Of course, in the case where the spring fixing plate 150 is not applied, one end of the torsion spring 140 is inserted and fixed in the spring fixing hole 73 formed on the side plate of the mounting frame 70 Need not be formed.

8, the memory lever 80 is formed with a connecting pin hole 81 at an intermediate portion thereof, and a spring fixing hole 82 is formed at a lower portion of the connecting pin hole 81 by a predetermined distance.

The memory lever 80 is formed at its lower end with an insertion end 83 that can be inserted into the through hole 62 of the latch bracket 60. The memory lever 80 is provided at both sides of the insertion end 83 with both side portions of the through hole 62 The latching protrusion 83a is formed.

On one side of the memory lever 80, an engaging groove 84 is formed in which a part of the set plate 90 is inserted and engaged.

The upper half and the lower half of the memory lever 80 are formed in the form of a step, and the lower half is formed to have a narrow width as compared with the upper half. The upper half of the memory lever 80 is moved up and down through a memory lever hole 71b formed in the upper plate of the mounting frame 70 and the lower half of the memory lever 80 is moved up and down through a memory lever hole 71a.

9, the set plate 90 includes fixing pinholes 91a and 91b corresponding to the fixed pinholes 74a and 74b of the mounting frame 70 on both sides of the rectangular body.

Therefore, the set plate 90 is disposed below the mounting frame 70 and the fixed pinholes 91a and 91b of the set plate 90 and the fixed pinholes 74a and 74b of the mounting frame 70, The set plate 90 is installed at the lower portion of the mounting frame 70 by inserting and fixing the fixing pins 131a and 131b.

 The fixed pinholes 91a and 91b of the set plate 90 are formed in the shape of an elongated hole extended to the left and right so as to correspond to the difference between the length of the fixed pinholes 91a and 91b and the diameters of the fixing pins 131a and 131b The set plate 90 can be moved forward / backward (left / right in the drawing) by a distance.

One end of the set plate 90 is bent downwardly to form a latching end 92. The latching end 92 is caught by the side surface of the base member 50 when the sheet returns to the home position after the work-in operation.

A spring mounting portion 93 having a linear shape is formed at the other end of the set plate 90 as compared with a portion where the fixing pin holes 91a and 91b are formed. (94) is formed.

A compression spring 160 is extruded into the spring mounting portion 93 and a spring pin 133 is inserted and fixed to the spring pin hole 94 so that one end of the compression spring 160 is supported on the spring pin 133. In the assembled state, the other end of the compression spring 160 is supported at one end of the mounting frame 70. Therefore, the compression spring 160 always serves to push the set plate 90 backward.

A memory lever groove 95 into which the lower half of the memory lever 80 is inserted is formed on one side surface of the body of the set plate 90. One end of the memory lever groove 95 (the front end of the vehicle body) acts as an engaging end 5a which is inserted into the engaging groove 84 of the memory lever 80 to engage.

As shown in FIG. 10, the lock lever 100 is a simple plate member having a 1/4 circular shape (sector) at one end and a semicircular shape at the other end, and a rotary shaft 120 A connecting pin hole 102 through which the connecting pin 132 is inserted and fixed is formed at the other end portion.

The lock lever 100 is integrally rotated with the pivot shaft 120 by the pivot shaft 120 being seated and fixed to the pivot shaft groove 101. The lock lever 100 and the rotary shaft 120 are welded to each other or coupled to each other via a key or a ring-like part having an internal gear in the rotary shaft groove 101 and an external gear is formed on the rotary shaft 120 In this case, the lock lever 100 is locked with respect to the pivoting direction of the pivot shaft 120 so that the internal gear is engaged with the external gear. In this case, It is only necessary that the lever 100 can rotate integrally with the pivot shaft 120. [

As shown in FIG. 11, the link lever 110 is formed in an approximately 8-letter shape and the upper and lower portions are rounded, but the shape of the link lever 110 is not particularly limited. A circular rotating shaft hole 111 is formed at one end of the link lever 110 and a wire hole 112 is formed at the other end of the link lever 110 on a concentric circle with the rotating shaft hole 111.

The link lever 110 is fixed to the pivot shaft 120 while the pivot shaft 120 is inserted into the pivot shaft hole 111 so that the link lever 110 is integrally rotated with the pivot shaft 120.

The wire hole 112 has a width expanded to the left and right so that the wire connection portion can move within the wire hole 112 when the wire is connected. This gap can be used when the wire is pulled when operating the seat back folding or the walk- So that the shock caused by the sudden pulling does not occur.

Now, the operation of the memory device which is a walk-in according to the present invention will be described with reference to Figs. 2, 3, and 12 to 14. Fig.

FIG. 2 shows a state in which the work-in-memory device is unlocked. In this state, both end portions of the torsion spring 140 are open, and the memory lever 80 presses one end of the latch bracket 60 at the lowered position.

The locking bracket 60 is rotated in the clockwise direction around the engaging pin 63 so that the locking end portion 61 is raised so that the locking end portion 61 is disengaged from the locking groove 41 of the guide rail 40 have.

The insertion end 83 of the memory lever 80 is inserted into the through hole 62 of the latch bracket 60 and is engaged.

Therefore, since the base member 50 is free to move relative to the guide rail 40, when the user operates the seat lock lever provided at the lower portion of the seat cushion (lifts it upward) and releases the seat lock state, The position can be freely adjusted.

Fig. 12 shows a state in which the user operates the operation lever, which is a workpiece, in order to operate the seat as a workpiece.

When the user operates the work-in operation lever, the interlocking wire is pulled and the lower end of the link lever 110 is pulled. The rotation shaft 120 is rotated in the clockwise direction together with the link lever 110 and the lock lever 100 is rotated clockwise integrally with the rotation shaft 120 to raise the connection pin 132, 132 of the memory lever 80 is lifted.

When the memory lever 80 rises, the insertion end 83 of the memory lever 80 is disengaged from the through hole 62 of the latch bracket 60 and can not push the latch bracket 60 anymore, Is rotated in the counterclockwise direction around the engagement pin 63 by the action of a torsion spring provided between the latch bracket 60 and the base member 50.

Therefore, the locking end portion 61 of the latch bracket 60 is lowered and inserted into the locking groove 41 of the guide rail 40, so that the base member 50 is fixed to the guide rail 40. That is, the position of the seat originally adjusted by the user is memorized by fixing the position of the base member 50.

Since the insertion end 83 of the memory lever 80 is detached from the through hole 62 of the latch bracket 60 as described above, the memory lever 80, the mounting frame 70 provided with the memory lever 80, The upper rail 20 on which the mounting frame 70 is mounted is allowed to move freely with respect to the lower rail 10.

Therefore, the seat is pulled by the spring which is provided between the seat track and the seat cushion frame and provides a driving force of a work-like operation (forward movement of the seat), so that the seat can be moved forward as shown in Fig.

That is, as the upper rail 20 is released from the restraint state with respect to the lower rail 10, the seat is walked forward, so that passengers can freely move up and down.

In this state, regardless of the forward movement of the seat, the base member 50 is moved to the position on the guide rail 40 that is locked by the latch bracket 60 (state in which the seat position is adjusted by the user before operation as a workpiece) It is fixed as it is.

When the memory lever 80 is lifted up, the engaging groove 84 of the memory lever 80 is pressed downward by the compression spring 160, The engaging end 95a is inserted into the engaging groove 84 and engaged with the set plate 90 as the set plate 90 moves backward. Therefore, the lifted position of the memory lever 80 is stably maintained while the seat is being walked forward or backward after being walked.

14, when the seat is moved backward, the latching end 92 of the set plate 90 is moved to the rear side of the base member 50 as shown in FIG. 14, Lt; / RTI >

Thus, the seat is stopped at the memorized position before the operation as a workpiece, and then the sheet is fixed by releasing the stroke release lever which is pulled to move the seat backward.

On the other hand, when the engaging end 92 is caught by the base member 50, the set plate 90 can not move further backward, The lock plate 95a is disengaged and the restraint state of the memory lever 80 by the set plate 90 is released.

The memory lever 80 is lowered again and the insertion end 83 of the memory lever 80 is retracted to the latch bracket 80. In this state, 60 so that the locking end 61 is disengaged from the locking groove 41. As a result,

Therefore, the restraint state of the base member 50 with respect to the guide rail 40 is released, and the front and rear positions of the seat can be adjusted.

On the other hand, the state shown in Fig. 14 differs from the state shown in Fig. 2 in that the memory lever 80 moves slightly beyond the center of the latch bracket 60 to the rear. In this case, the insertion end 83 of the memory lever 80 does not coincide with the position of the through hole 62 of the latch bracket 60, so that the insertion end 83 may not be correctly inserted into the through hole 62.

In order to prevent this, it is preferable to provide the spacer 54 at the contact portion of the engaging end 92 of the set plate 90 of the base member 50.

The spacer 54 has a thickness equal to the distance between the center of the memory lever 80 and the center of the through hole 62 of the latch bracket 60 when the spacer 54 is not present.

Therefore, when the seat is returned to the rear after the workpiece is loaded with the spacers 54 installed, the latching end 92 of the set plate 90 is caught by the spacer 54 and the set plate 90 is stopped The memory lever 80 and the set plate 90 are separated from each other at a position where the insertion end 83 of the memory lever 80 and the center of the through hole 62 of the latch bracket 60 coincide with each other The insertion end 83 of the memory lever 80 can be inserted into the through hole 62 of the latch bracket 60 more easily and accurately.

The spacers 54 are preferably made of an elastic material such as rubber so as to absorb shock to reduce the noise generated when the engaging ends 92 of the set plate 90 made of a metal collide with each other.

According to the present invention as described above, the sheet after operation as a workpiece is returned to the position where the sheet was fixed before operation as a workpiece. Therefore, the position of the sheet set by the user in the normal operation can be maintained even after the work-in operation is performed. That is, it is possible to freely set the return position of the seat after the user is in the seat, which is a work memory.

Further, since the seat is correctly stopped and fixed at the position set by the user when the seat is returned to the rear after the work is done, the inconvenience of repositioning the seat after the seat is returned back is eliminated.

In addition, the walk-in memory device is installed in the space between the lower rail and the upper rail, that is, the inner space of the seat track, so that the seat cushion frame and the seat track are very clean and simple.

In addition, since the walk-in memory device is installed in an empty space in the seat track and does not cause an increase in the height of the seat, the layout of the vehicle body can be reduced overall.

Further, when the seat is returned to the rear, the impact force generated by the collision between the set plate and the base member is blocked at the set plate and is not transmitted to the memory lever. Therefore, deformation and breakage of the memory lever are prevented, so that failure of the device is prevented, and stability and reliability of the device operation are improved.
