Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slide sheet that can be stored sideways.
[0002]
[Prior art]
For the rear seat (second seat or third seat) of the car, the seat back is tilted to the rear side to make the luggage compartment behind the rear seat horizontal, and the entire rear seat is raised centering on the outside end of the seat cushion. There is a horizontal bounce storage type structure that rotates and stores.
[0003]
A seat bracket is attached to the outer end of the seat cushion, and the seat bracket is attached to a first slide rail fixed to the floor, and is supported by a rail bracket that can move back and forth so as to be rotatable in a horizontal recoil direction. Have been.
[0004]
On the other hand, the inner end portion of the seat cushion is also supported by the second slide rail so as to be able to move back and forth, and is also capable of engaging and disengaging with respect to the second slide rail in order to allow the seat cushion to be stored horizontally. ing.
[0005]
The first slide rail and the second slide rail are provided with a first lock mechanism and a second lock mechanism, respectively, for fixing the front and rear positions.
[0006]
An operation lever for releasing the first lock mechanism is provided on a side surface of the seat bracket attached to the outer end of the seat cushion on the rail bracket side. The operation lever is a rotary operation type by lifting or the like, and by operating this operation lever, at least the first lock mechanism can be released.
[0007]
When transmitting the operation force of the operation lever to the first lock mechanism of the first slide rail, the seat bracket provided with the operation lever is rotatable with respect to the rail bracket supported by the first slide rail. The operation force transmission structure between the bracket and the rail bracket is complicated.
[0008]
That is, in the normal use state of the seat cushion, the seat bracket side and the rail bracket side must be engaged with each other, and the operating force must be transmitted. The seat bracket and the rail bracket must be automatically re-engaged when they are disengaged and returned to their original normal use condition.
[0009]
Therefore, a strict positional relationship is required for the engagement structures on the seat bracket side and the rail bracket side, and if the positions of the engagement-related parts are displaced from each other, the seat cushion is re-engaged when the seat cushion is returned to the normal use state. In addition, not only the transmission of the operation force becomes impossible, but also the engagement-related parts interfere with each other at incorrect positions, and the engagement structure may be damaged.
[0010]
Therefore, in order to reliably obtain the engaged state and the disengaged state by the approach and separation of the seat bracket and the rail bracket, for example, a pin movable on the seat bracket side by rotating the operation lever is provided, An operating force is transmitted from the pin to the internal structure of the passive unit by inserting and removing the pin from a hole provided in the passive unit on the rail bracket side (for example, see Patent Document 1).
[0011]

[Problems to be solved by the invention]
However, in such a conventional technique, a pin provided on a seat cushion side is inserted into and removed from a hole provided on a passive portion on a rail bracket side, so that the seat bracket and the rail bracket are connected to each other. Although the engaged state and the disengaged state can be reliably obtained at the time of approaching / separating, since the operation lever is provided in a protruding state on the seat bracket, the user can hold the seat cushion by hand and jump sideways. When returning from the stowed state to the original use state, the operator's hand accidentally touches the operation lever, and the operation lever rotates, so that the position of the engagement-related parts (for example, pins) on the seat bracket side is in the proper position. From the first slide rail, and may not accurately engage with the structure on the passive portion side of the first slide rail. If the seat bracket and the rail bracket do not engage with each other correctly, not only the operation force of the operation lever cannot be transmitted, but also the structure of each other may be deformed or damaged.
[0013]
The present invention has been made by paying attention to such a conventional technology, and when returning the seat cushion to the original use state, even if the operator accidentally touches the operation lever, the seat bracket on the seat cushion side and the second An object of the present invention is to provide a laterally recoil type slide sheet that can accurately re-engage with a rail bracket on one slide rail side.
[0014]
[Means for Solving the Problems]
According to the first aspect of the present invention, a seat bracket is attached to an outer end portion of a seat cushion provided with a seat back that can be tilted rearward, and is moved forward and backward by a first slide rail on a first slide rail fixed to a floor. A free rail bracket is attached, the seat bracket is supported on the rail bracket so as to be rotatable in the horizontal recoil direction together with the seat cushion, and the inner side end of the seat cushion can be moved back and forth by a second slide rail, and (2) A side-retractable slide sheet, which is detachably attached to the slide rail and has an operating lever for releasing the lock mechanism of the first slide rail rotatably mounted on the side surface of the seat bracket on the rail bracket side. A part of the operating lever is in contact with the side of the seat bracket to which the operating lever is attached. A stopper member capable of preventing rotation operation of the operation lever is provided in a state where the stopper member is urged to the side surface side, and an operation pin that penetrates the side surface portion and protrudes toward the rail bracket side is formed on the stopper member, In the normal use state of the seat cushion, the tip of the operating pin is pressed by the rail bracket, and the stopper member separates from the side portion against the urging means, thereby enabling the operation lever to rotate, thereby enabling the seat cushion to be rotated. In the horizontal recoil storage state, the pressing of the operating pin by the rail bracket is released, and the stopper member is biased to a position where it abuts a part of the operating lever by the biasing means, thereby disabling the rotation operation of the operating lever. It is characterized by doing.
[0015]
According to the first aspect of the present invention, in the state in which the seat cushion is horizontally recoiled, the operation lever cannot be rotated by the contact with the stopper member. When returning to the use state, the operation lever does not rotate even if it touches the operation lever by mistake. Accordingly, the engagement-related components on the seat bracket side of the seat cushion do not shift, and the seat bracket and the rail bracket can be accurately re-engaged. In addition, in the normal use state, the operating lever of the stopper member is pressed by the rail bracket so that the operating lever can be rotated. Therefore, there is no problem in the operability of the operating lever.
[0016]
According to the second aspect of the present invention, the operation lever and the lock mechanism on the second slide rail side are connected by an operation force transmitting means, so that the lock mechanism for the first slide rail and the lock mechanism for the second slide rail are connected. Can be simultaneously released.
[0017]
According to the second aspect of the present invention, since the lock mechanisms of the first slide rail and the second slide rail can be simultaneously released by the rotation operation of the operation lever, the release operation of the lock mechanism is easy.
[0018]
The invention described in claim 3 is characterized in that the position of the second slide rail when the inner end portion of the seat cushion is detached is maintained as it is.
[0019]
According to the third aspect of the present invention, since the position of the second slide rail is maintained as it is, when the seat cushion is returned to the original state, the inner end of the seat cushion is positioned with respect to the second slide rail. Re-engage exactly.
[0020]
According to a fourth aspect of the present invention, the first slide rail is higher than the second slide rail, and the inner end portion of the seat cushion is supported on the lower surface of the seat cushion so as to be freely foldable. It is characterized by being.
[0021]
According to the fourth aspect of the present invention, since the foldable legs are provided on the lower surface of the seat cushion, the seat cushion can be reliably secured even if the first slide rail and the second slide rail have different vertical heights. And can be supported to be able to move back and forth. In the state in which the seat cushion is in the horizontal recoiled state, the legs do not protrude toward the enlarged luggage compartment when the legs are folded.
[0022]

The first movable rail 10 has an L-shaped cross section, and the second movable rail 11 has a T-shaped cross section. The first movable rail 10 is moved back and forth with respect to the first fixed rail 8 and the second fixed rail 9 by rollers 12 (see FIGS. 4 and 5). It is free.
[0029]
A rail bracket 13 is fixed to the upper surface of the first movable rail 10, and a seat bracket 14 integrated with the outer end of the seat cushion 2 at the front and rear ends of the rail bracket 13 is provided around a rotation axis X. And are rotatably supported.
[0030]
The seat bracket 14 is fixed to the cushion frame 15 inside the seat cushion 2, and the entire seat cushion 2 can be turned around the rotation axis X with respect to the rail bracket 13 to be in a side-bounce storage state.
[0031]
An operation lever 18 is pivotally supported by a shaft pin 16 on a side surface of the seat bracket 14 on the rail bracket 13 side so as to be rotatable. The front end of the operation lever 18 projects forward from a slit 21 formed in the front wall of the seat bracket 14.
[0032]
An L-shaped action lever 23 is rotatably supported at the rear end of the operation lever 18. A pin 24 is formed at the front end of the action lever 23. By engaging the pin 24 with the rear end of the elongated hole 25, the rotation of the action lever 23 is restricted, and the action lever 23 is rotated together with the operation lever 18 in the lifting direction. .
[0033]
The action lever 23 can rotate to the opposite side with respect to the operation lever 18 by the movement of the pin 24 in the long hole 25. By rotating the action lever 23 to the opposite side, even if a load on the opposite side is applied to the mechanism connected to the action lever 23, the load can be absorbed and the mechanism can be protected.
[0034]
A link plate 27 is connected to a rear end of the action lever 23 via a link shaft 26, and the link plate 27 is connected to an upper end of a swing lever 28 that can swing back and forth around a lower end.
[0035]
A movable pin 30 is formed on the swing lever 28 so as to protrude outside through an arc hole 29 formed in the seat bracket 14. The movable pin 30 can be inserted into a long hole 33 of a cam plate 32 fixed to one end of a shaft 31 that penetrates the upper part of the rail bracket 13.
[0036]
When the operation lever 18 is rotated upward, the swing lever 28 rotates forward via the above-described action lever 23, link shaft 26, and link plate 27, and the movable pin 30 is moved into the long hole 33 of the cam plate 32. The shaft 31 is rotated by swinging forward while being engaged.
[0037]
A rotating plate 34 is fixed to the other end of the shaft 31, and the lower end of the rotating plate 34 pushes the front end of a first lift lever 35 rotatably supported as shown in FIG. The interlock 36 is raised to allow the first movable rail 10 to move back and forth.
[0038]
The first interlock 36 is constantly urged downward, and normally engages with a plurality of notches (not shown) formed on the bottom surface of the first fixed rail 8 to move forward and backward of the first movable rail 10. Locked position. The cam plate 32, the shaft 31, the rotating plate 34, the first lift lever 35, and the first interlock 36 constitute a “first lock mechanism”.
[0039]
As shown in FIGS. 8 to 11, a stopper member 17 is provided on a side surface portion of the seat bracket 14 to which the operation lever 18 is attached, at an upper rear position of the operation lever 18. The stopper member 17 is provided in the middle of an operation pin 19 that penetrates the seat bracket 14, and is supported by a bracket 20 having a U-shaped cross section. A spring (biasing means) 22 is provided between the bracket 20 and the stopper member 17 to urge the stopper member 17 toward the seat bracket 14.
[0040]
The operating pin 19 is pressed by the rail bracket 13 in the normal use state of the seat cushion 2 to separate the stopper member 17 against the spring 22.
[0041]
Accordingly, when the seat cushion 2 is placed in the sidewardly retracted state and the pressing of the operating pin 19 is released, the stopper member 17 is pressed against the seat bracket 14 (FIG. 10), and the seat cushion 2 is brought into the normal use state. The operating pin 19 is pressed by the rail bracket 13 and is separated from the seat bracket 14 (FIG. 11).
[0042]
When the stopper member 17 is in contact with the seat bracket 14, the corresponding end of the operation lever 18 abuts on the stopper member 17, so that the operation of the operation lever 18 is disabled, and the non-operation state of the operation lever 18 is maintained. You.
[0043]
When the stopper member 17 is separated from the seat bracket 14, the corresponding end of the operation lever 18 enters between the stopper member 17 and the seat bracket 14, so that the operation lever 18 can be rotated.
[0044]
On the other hand, the cushion frame 15 at the inner end of the seat cushion 2 has a leg portion 37 that can be freely folded around the upper end toward the lower surface of the seat cushion 2.
[0045]
The leg 37 is for compensating a difference in vertical height between the first slide rail 6 and the second slide rail 7, and a spring (not shown) is provided at a pivot point of rotation of the leg 37 with respect to the cushion frame 15. The seat cushion 2 is pulled out from the lower surface of the seat cushion 2 and can be held in a state of being rotated and a state of being folded on the lower surface with a constant urging force.
[0046]
When the leg 37 is pulled out, the lower end thereof is detachably attached to the second movable rail 11 of the second slide rail 7.
[0047]
A T-shaped lever 38 that is rotatable about a fulcrum at a central portion is provided at a position closer to the front of the leg 37. The lower end of the T-shaped lever 38 is pivotally supported near the lower end of the link lever 39.
[0048]
The link lever 39 has a large vertical size, and its lower end swings about a fulcrum at its upper end. Between the upper end of the link lever 39 and the front end of the T-shaped lever 38, a spring 40 for pulling both is provided, and the spring 40 prevents rattling of both.
[0049]
The rear end of the T-shaped lever 38 and the swinging lever 28 to which the movable pin 30 is fixed are connected by a wire 41. The wire 41 is covered with an outer tube 42 having both ends fixed, and the amount of movement of the wire 41 relative to the outer tube 42 on one side is transmitted to the other side irrespective of the path and the degree of bending. However, some errors occur due to the relationship between the wire 41 and the inner diameter of the outer tube 42.
[0050]
Since a pulling force from a spring 49 is applied to the wire 41, the wire 41 is pulled by the pulling force, and the swing lever 28 is rotated rearward. Accordingly, the operation lever 18 is always urged to be in the non-operation state.
[0051]
The "operating force transmitting means" of this embodiment is formed by the wire 41, the T-shaped lever 38, the link lever 39, and the like as described above.
[0052]
Therefore, when the operation lever 18 is rotated upward, the wire 41 is pulled by a predetermined stroke via the swing lever 28 on the first lock mechanism side, and the T-shaped lever 38 on the leg 37 side is rotated.
[0053]
When the T-shaped lever 38 rotates, the lower end of the link lever 39 also swings rearward about the upper fulcrum. Since the vertical size from the upper fulcrum to the lower end of the link lever 39 is large, the lower end of the link lever 39 rotates rearward in a large arc close to horizontal movement.
[0054]
A U-shaped striker 43 is welded to the rearward position of the leg 37. The leg 37 is detachably attached to the second slide rail 7 using the striker 43.
[0055]
An opening (not shown) is formed in a portion of the second movable rail 11 corresponding to the striker 43, and the striker 43 is inserted from the opening to the inside of the second movable rail 11.
[0056]
A catch 44 is provided on a portion of the second movable rail 11 corresponding to the striker 43 so as to be rotatable around a lower fulcrum. The upper portion of the catch 44 has a hook shape having an engagement recess, and the striker 43 is engaged with the engagement recess.
[0057]
The catch 44 is constantly urged in a direction of detaching from the striker 43 (to rotate forward), and the cam 45 engaging with a recess in front of the catch 44 prevents the catch 44 from rotating in the detaching direction. Have been.
[0058]
An auxiliary plate 46 whose front end is coaxially supported is provided on the rotation shaft of the cam 45. The rear end of the auxiliary plate 46 is pivotally supported at a position behind the fulcrum at the lower end of the catch 44, and is pressed downward by the striker 43 to forcibly rotate the catch 44 in the engagement direction. .
[0059]
A projection 47 is formed in front of the lower end of the catch 44, and engages with a not-shown notch formed on the bottom surface of the second fixed rail 9 when the catch 44 rotates in the detaching direction. The longitudinal movement of the movable rail 11 with respect to the second fixed rail 9 can be locked.
[0060]
A release rod 48 is connected to the cam 45 that prevents the catch 44 from rotating in the detaching direction, and a front end of the release rod 48 projects as a release portion 49 forward of the second movable rail 11. .
[0061]
The release rod 48 is urged in the direction in which the cam 45 is engaged with the catch 44 (toward the rear side). By pulling the release portion 49 forward and moving the release rod 48 forward, the cam 45 is disengaged from the recess of the catch 44, and the catch 44 rotates in the disengagement direction by the urging force, and engages with the striker 43. Is released.
[0062]
At a position slightly forward of the catch 44 on the vertical surface of the second movable rail 11, a second lift lever 50 whose lower end is pivotally supported and whose front end swings up and down and whose upper end swings back and forth is provided. ing. At the front end of the second lift lever 50, a second interlock 51 is pivotally supported. The second interlock 51 is engaged with a plurality of notches (not shown) formed in the bottom surface of the second fixed rail 9 at an arbitrary position to move the second movable rail 11 forward and backward with respect to the second fixed rail 9. Lock.
[0063]
A rear end of the push rod 52 that extends horizontally to the front side is supported at the upper end of the second lift lever 50. An opening (not shown) is formed near the front end of the push rod 52, and the lower end of the link lever 39 of the leg 37 is inserted through the opening. The push rod 52, the second interlock 51, and the second lift lever 50 constitute a "second lock mechanism".
[0064]
A downward biasing force is constantly applied to the second interlock 51, and the locked state of the second movable rail 11 with respect to the second fixed rail 9 is maintained.
[0065]
When the lower end of the link lever 39 pushes the front end of the push rod 52 backward, the second lift lever 50 rotates and lifts the second interlock 51, so that the second movable rail 11 is Can be moved back and forth with
[0066]
A detachable belt hook 53 is provided at a position closer to the inside of the lower surface of the seat cushion 2 (see FIG. 1). The belt hook 53 can be detached from the seat cushion 2 and hooked on the assist grip 54 of the vehicle body in order to hold the seat cushion 2 in the horizontally recoiled state.
[0067]
Next, the operation in each state of the slide sheet of this embodiment will be described with reference to FIGS.
[0068]
Normal seating state (see FIG. 12) : In a normal seating state, the first interlock 21 is engaged with the first fixed rail 8 on the first slide rail 6 side, and the second interlock 21 is on the second slide rail 7 side. Since the two interlocks 51 are engaged with the second fixed rail 9, the forward and backward movement of the rear seat 1 is locked.
[0069]
Further, since the striker 43 of the leg 37 is also engaged with the catch 44, the seat cushion 2 does not bounce sideways. The lower end of the link lever 39 is inserted into the front end of the push rod 52 from above.
[0070]
In the operation lever 18, the operating pin 19 of the stopper member 17 is pressed by the rail bracket 13, and the stopper member 17 is separated from the seat bracket 14. Therefore, the operation of turning the operation lever 18 is enabled.
[0071]
Operation state of operation lever 18 (see FIG. 13) : Next, the operation lever 18 is rotated upward. Then, since the swing lever 28 swings forward via the action lever 23, the link shaft 26, and the link plate 27, the movable pin 30 rotates the cam plate 32.
[0072]
Then, the rotation is transmitted to the rotating plate 34 via the shaft 31, and the rotating plate 34 rotates the first lift lever 35, so that the first interlock 36 is lifted and the first slide rail 6 is unlocked. .
[0073]
Further, the wire 41 is pulled by the swing lever 28, the T-shaped lever 38 and the link lever 39 rotate, and the push rod 52 is pushed by the substantially horizontal movement of the lower end of the link lever 39.
[0074]
When the push rod 52 is pushed, the second lift lever 50 rotates, the second interlock 51 is lifted, and the lock of the second slide rail 7 is released. In this manner, by rotating the operation lever 15, both the first slide rail 6 and the second slide rail 7 can be unlocked at the same time, so that the occupant can move the rear seat 1 back and forth while sitting.
[0075]
Detachment state from second slide rail 7 (see FIG. 14) : Next, when the leg portion 37 is detached from the second slide rail 7 and the rear seat 1 is to be stored horizontally, the front of the second slide rail 7 is set. Pulling the release portion 49, the release rod 48 is moved forward.
[0076]
Then, the cam 45 is disengaged from the recess of the catch 44, and the catch 44 is rotated by its own urging force, and disengaged from the striker 43. In addition, the protrusion 47 of the catch 44 engages with a notch (not shown) of the second fixed rail 9 to lock the second slide rail 7.
[0077]
Since the catch 44 and the striker 43 are disengaged, after the seat cushion 2 is tilted backward, the entire rear seat 1 is lifted about the rotation axis X of the seat bracket 14 and the rail bracket 13 to be in a side-bounce storage state. be able to.
[0078]
When the leg 37 is separated from the second slide rail 7, the push rod 52 cannot be pushed, so that the locked state of the second slide rail 7 is maintained. As described above, the locking state of the second slide rail 7 is reliably maintained because there is also engagement by the projection 47 of the catch 44.
[0079]
Therefore, even if the luggage is placed on the floor 5 used as a luggage compartment and the luggage hits the second slide rail 7, the state of the second slide rail 7 does not change after the side bounce storage state.
[0080]
Also on the first slide rail 6 side, the locked state of the first slide rail 6 is maintained because the first interlock 36 is engaged with the first fixed rail 8 by its own urging force.
[0081]
Therefore, the rear seat 1 in the side recoil storage state does not move back and forth. When the rear seat 1 is lifted up and enters the side-up storage state, the belt-hook 53 is hooked on the assist grip 54 on the side wall of the vehicle body, so that the side-up storage state is maintained. Since the leg portion 37 is folded toward the lower surface of the seat cushion 2, it does not protrude toward the enlarged cargo room.
[0082]
Also, when returning from the side-bounce storage state to the original state, as described above, both the first slide rail 6 and the second slide rail 7 are locked at the position where the seat cushion 2 remains in the side-bounce state. Therefore, the leg 37 and the second slide rail 7 are accurately re-engaged when they are restored.
[0083]
The striker 43 of the leg 37 is accurately aligned with the catch 44 of the second slide rail 7, and the striker 43 presses the auxiliary plate 46, so that the catch 44 stands up against the urging force and re-engages with the striker 43. I do. When the catch 44 rises, the cam 45 is accordingly engaged in the recess by its own urging force, and the engagement state of the catch 44 is maintained.
[0084]
Further, even if the operation lever 18 is accidentally touched when the seat cushion 2 is returned to the original position, the pressing of the operation pin 19 of the stopper member 17 is released when the seat cushion 2 is made to be in the horizontal recoil state. Since the stopper member 17 is in contact with the corresponding end of the seat bracket 14 to disable the operation of the operation lever 18, the operation lever 18 does not move.
[0085]
Therefore, the position of the movable pin 30 fixed to the swing lever 28 does not change, and when the seat cushion 2 is returned, the movable pin 30 is accurately inserted into the long hole 33 of the cam plate 32, and the operating force of the operating lever 18 is adjusted. In an engagement state in which the power can be transmitted.
[0086]
After the movable pin 30 is accurately engaged in the long hole 33 of the cam plate 32 and returns to the normal use state, the operating pin 19 is pressed again by the rail bracket 13 and the stopper member 17 Since the operation lever 18 is displaced from the position where it comes into contact with the corresponding end, the operation lever 18 can be turned.
[0087]
【The invention's effect】
According to the present invention, when the seat cushion is in the horizontal recoil storage state, the operation lever cannot be rotated by the contact with the stopper member. Therefore, when the seat cushion is returned from the horizontal recoil storage state to the original use state. Even if the operator accidentally touches the operating lever, the operating lever does not rotate. Accordingly, the engagement-related components on the seat bracket side of the seat cushion do not shift, and the seat bracket and the rail bracket can be accurately re-engaged. In addition, in the normal use state, the operating lever of the stopper member is pressed by the rail bracket so that the operating lever can be rotated. Therefore, there is no problem in the operability of the operating lever.
