Description

  The present invention relates to a vehicle seat. Specifically, the seat with the seat back folded to the seat cushion side is slid up to an avoidance position that does not interfere with an obstacle such as a tire house on the floor, and is raised and rotated toward a target site such as a side wall. The present invention relates to a vehicle seat in which the seat is retracted.

2. Description of the Related Art Conventionally, some rear seats of a vehicle such as an automobile are provided with a mechanism that can be stored in a state in which a seat back and a seat cushion are folded and stood up at a side wall position in a vehicle interior space. As a result, when the rear side seat is not used, it can be stored in the side wall position, and a larger cargo space can be secured.
By the way, a specific configuration of such a storage mechanism is disclosed in, for example, Patent Document 1 described later, which is a technique previously proposed by the present applicant. In this disclosure, the vehicle seat is provided with a reclining mechanism that allows the seat back to be folded toward the seat cushion. Further, the seat cushion is provided with a cushion lock that allows the seat cushion to be fixedly locked to the floor in a state where the seat cushion is laid down on the floor at the bottom surface portion inside the vehicle. Further, a hinge mechanism is provided on the vehicle window side (side wall side) of the bottom surface portion so that the seat cushion can be rotated in a direction to rise from the floor toward the vehicle window side with the cushion lock released. Further, a slide mechanism that allows the seat cushion to slide in the vehicle front-rear direction relative to the floor is disposed at a lower position of the hinge mechanism. Therefore, according to this vehicle seat, for example, even when an obstacle such as a tire house is formed as a shape protruding from the floor at a target portion where the seat is raised and rotated, Can be placed in the retracted state in a state in which it is slid to the avoidance position where it does not interfere with the obstacle.
JP-A-11-115577

However, in the above-described conventional technique, a series of operations for making the retracted state in which the seat is slid and moved to an avoidance position where the seat does not interfere with an obstacle such as a tire house is very troublesome. Specifically, in order to slide the seat to the avoidance position by the slide mechanism, first, the seat with the seat back folded to the seat cushion side is turned upright to lift the cushion lock from the floor. Necessary. At this time, the angle at which the seat is erected and rotated must be kept to the tilt angle position before the seat interferes with the obstacle. When the seat is slid to the avoidance position, the operator always has to perform the moving operation while supporting the seat in the inclined posture state.
In general, a seat cushion and a seat back folded by the seat cushion are configured such that the surface is covered with a flexible material such as a urethane pad. Therefore, for example, even when the seat is in a positional relationship where it can interfere with an obstacle, by applying a force to turn the seat upright to the retracted position, the interference force with the obstacle can cause the elasticity of the urethane pad. The sheet may be absorbed by the deformation and the sheet storage state may be established. For this reason, for example, when a person unfamiliar with the operation performs a storing operation, the sheet is unexpectedly flipped up and the sheet may be forcedly stored. As a result, an excessive load is applied to an interference portion such as a urethane pad, which may cause damage.

  The present invention was devised as a solution to the above-described problem, and the problem to be solved by the present invention is to place the seat in the retracted state while sliding the seat to an avoidance position that does not interfere with the obstacle. In addition to simplifying the series of operations, it is possible to restrict storage operations from being performed at inappropriate positions.

In order to solve the above problems, the vehicle seat of the present invention takes the following means.
First , a first invention is a reclining mechanism provided at a connecting portion between a seat back and a seat cushion, which allows the seat back to be folded to the seat cushion side, and the seat cushion in a state where the seat cushion is lying on the floor. A cushion lock that can be locked against the seat, a hinge mechanism that allows the seat cushion to be rotated with respect to the floor with the cushion lock released, and a seat that is disposed at a lower position of the hinge mechanism And a sliding mechanism that allows the cushion to slide relative to the floor, and the seat with the seat back folded toward the seat cushion is slid to an avoidance position that does not interfere with an obstacle such as a tire house on the floor. By standing up and turning toward the target part such as the side wall in the state Sheet Ru der for the vehicle to the over door and storage state. This vehicle seat is provided as an urging member for the folded seat, and when the urging member that urges the seat to rotate in the upright direction, and the sliding position of the seat is at a position that interferes with an obstacle, And a holding mechanism that holds the position by restricting the biasing rotation of the sheet to the rotation angle position before the interference with the obstacle . The holding mechanism is released from the holding state when the slide mechanism is slid to the avoidance position where the sheet does not interfere with the obstacle.
According to the first invention, the seat in which the seat back is folded to the seat cushion side by the reclining mechanism is urged in the standing direction by the rotation urging member when the cushion lock is released. It rotates around the hinge mechanism. And if the urging | biasing rotation angle of a sheet | seat reaches | attains the rotation angle position before interfering with an obstruction, a holding mechanism will hold | maintain in the state which controlled the rotation to the standing direction of a sheet | seat. Accordingly, since the sheet is automatically held at the angular position in the middle of the rotation, it is possible to move to an avoidance position that does not interfere with an obstacle only by applying a force in the direction of sliding the sheet. The holding state of the holding mechanism described above is released in conjunction with this by sliding the sheet to the avoidance position.

Next , in a second aspect based on the first aspect described above, the rotation urging member is a torsion spring member assembled to the hinge pin of the hinge mechanism. The holding mechanism includes a latching lock mechanism in which a latching portion coupled to the movable side member of the hinge mechanism is latched and locked to a latched portion coupled to the stationary member of the hinge mechanism, and the rotation of the seat in the standing direction is restricted. When the release link connected to the fixed side member of the hinge mechanism passes through the hook portion disposed on the slide rail of the slide mechanism, it engages and rotates to move the hook portion in the hook lock state from the hook portion. And a link mechanism that operates in the direction of removal.
According to the second aspect of the invention, the rotation urging means and the holding mechanism constituting the seat storing mechanism are each assembled to the hinge mechanism. Accordingly, such a configuration does not become an obstacle when the sheet is stored and used.

The present invention can obtain the following effects by taking the above-described means.
First , according to the first invention, it is possible to simplify a series of operations in which the seat is slid and moved to the avoidance position where it does not interfere with the obstacle and the storage state is set. Further, when the seat storing operation is performed at an inappropriate position (sliding position), the urging rotation angle of the sheet can be restricted to the rotation angle position before the interference with the obstacle. Therefore, it is possible to prevent an erroneous operation when the sheet is stored.
Furthermore, according to the second invention, the overall construction of a sheet storage mechanism can be made compact.

A fixed bracket 32 attached thereto, and the brackets 31 and 32 are pin-connected by a hinge pin 33. Thereby, the brackets 31 and 32 are coupled so as to be capable of relative rotation. In addition, although the hinge mechanism 30 is arrange | positioned by a pair at the vehicle front-back side, since the hinge mechanism of a rear side is a well-known thing, description is abbreviate | omitted. Therefore, the seat 1 can be rotated in the up-down direction with respect to the floor F with the hinge pin 33 of the hinge mechanism 30 as the rotation center. Here, the rotation bracket 31 corresponds to the movable side member of the present invention, and the fixed bracket 32 corresponds to the fixed side member of the present invention.
Specifically, as shown in FIG. 4, a seat attachment portion 31 a that functions as an attachment portion for the seat cushion 3 is formed in the turning end portion of the turning bracket 31. Further, as well shown in FIG. 3, a hook connecting portion 31c for connecting a hook 51 of a latching lock mechanism 50 described later is formed on a side surface portion 31b on the rear side of the vehicle. Further, the fixed bracket 32 is formed with a stopper portion 32b that functions as a stopper of a release mechanism 70 described later on a surface portion (inner surface portion 32a) inside the vehicle. Furthermore, hook portions 32d and 32e for hooking spring members 74a and 74b for urging the release mechanism 70 toward the normal posture are provided on the side surface portion 32c in front of the vehicle.
Next, the torsion spring member 40 is disposed in a state assembled around the hinge pin 33 of the hinge mechanism 30 described above, as well shown in FIG. Specifically, the one end side portion of the torsion spring member 40 is hooked on the rotating bracket 31 side, and the other end side portion is hooked on the fixed bracket 32 side. And it is assembled | attached as the state twisted beforehand so that the sheet | seat 1 may be urged | biased in the standing direction.

Specifically, the latching lock mechanism 50 includes a hook 51 attached to the rotating bracket 31 side of the hinge mechanism 30 and a stopper pin 52 attached to the fixed bracket 32 side. Here, the hook 51 corresponds to the engaging portion of the present invention, and the stopper pin 52 corresponds to the engaged portion of the present invention.
More specifically, as shown in FIG. 3, the hook 51 is formed in a plate shape as a whole, and its upper end portion is pin-coupled to the hook connecting portion 31 c of the rotating bracket 31 (coupling pin P1). The lower end portion has a hook shape that can be engaged with the stopper pin 52. Further, a spring member 53 is attached to the pin coupling portion (coupling pin P1) of the hook 51 so as to urge the hook 51 toward the stopper pin 52. Thereby, the hook 51 is always held in a state of being pressed to a position where the stopper pin 52 is located. The stopper pin 52 is integrally attached to the side portion 32f of the fixed bracket 32 on the rear side of the vehicle. As shown well in FIG. 4, when the seat 1 is in the normal posture, the hook 51 is disposed in a state in which the hook-shaped portion is spaced downward from the stopper pin 52 (the position indicated by the two-dot chain line in FIG. 4). State).
Therefore, the hook 51 moves upward by raising the seat 1 around the hinge mechanism 30 from the position of the normal posture state, as well shown in FIG. Then, when the hook-shaped portion comes into contact with the stopper pin 52 and enters the engagement lock state (position state indicated by the solid line in the figure), the upward movement of the hook 51 is restricted. Thereby, rotation to the standing direction of the sheet | seat 1 in a connection state with the hook 51 will be controlled. Here, the position where the hook 51 and the stopper pin 52 are engaged and locked is set to be the rotational angle position before the seat 1 interferes with the tire house H.
The hook 51 is integrally attached with a long plate-shaped substitute plate 51a having substantially the same size as being overlapped in the plate thickness direction. Specifically, as well shown in FIG. 5, the proxy plate 51 a is configured to be engaged with an engaging portion 51 b formed on the hook 51, and is a spring that is integrated with the hook 51 by a spring member 53. The force is received and pressed toward the stopper pin 52. Further, when the release mechanism 70 described later operates to release the hook 51 locked state, the substitute plate 51a receives this operating force in place of the hook 51 and indirectly releases the hook 51. Has been.

Next, as well shown in FIG. 3, the slide mechanism 60 includes a slide rail 61 extending in the vehicle front-rear direction and a hooking portion 62 disposed on the slide rail 61. Since the configuration of the slide mechanism 60 is a known technique, only the main part will be briefly described.
That is, the slide rail 61 includes a lower rail 61b that is integrally attached to the floor F, and an upper rail 61a that is inserted into the lower rail 61b and is slidable in the vehicle front-rear direction. The slide mechanism 60 is assembled with a lock portion (not shown) that can lock the slide movement of the upper rail 61a. The locking portion is configured to be able to mesh and lock with a meshing hole (not shown) formed through the side wall surfaces of the upper rail 61a and the lower rail 61b, and can be operated by rotating the release lever L (see FIG. 2) described above. The meshing lock state and the release state can be switched.
Moreover, the hook part 62 is formed as a shape obtained by bending a plate-like member into an L shape. Further, the L-shaped upper end portion is bent in the direction toward the vehicle inner side in the attached state of FIG. 3, and is formed as an overhang portion 62a. When the seat 1 is slid and moved along the slide rail 61 to the rear avoidance position where it does not interfere with the tire house H, the hook portion 62 is engaged with a release mechanism 70 described later. It is arranged. Specifically, the hooking portion 62 is integrally attached to the bottom surface portion of the lower rail 61b inside the vehicle, and the overhanging portion 62a extends from the side wall surface of the lower rail 61b toward the inside of the vehicle. ing.

Next, the release mechanism 70 is arranged in a state assembled to the hinge mechanism 30 as well shown in FIG. Specifically, the release mechanism 70 includes a release link 71 that is pin-coupled to the fixed bracket 32 of the hinge mechanism 30 (a coupling pin P2), and a pin that can be interlocked with the operation of the release link 71 with respect to the fixed bracket 32. An interlocking bracket 72 and a removal link 73 that are coupled (coupling pin P3) are provided.
Specifically, as shown in FIG. 3, the release link 71 is formed as a shape in which a plate-like member forms a T shape, and this T-shaped connecting portion is pin-coupled to the fixing bracket 32 ( The coupling pin P2). In addition, an engaging portion 71 a having a length that can be engaged with the hook portion 62 is formed on the T-shaped leg portion of the release link 71. Therefore, as shown in FIG. 5, when the seat 1 is slid along the slide rail 61 to a rear avoidance position that does not interfere with the tire house H, the engaging portion 71 a It engages with 62a and rotates clockwise as shown in FIG. As shown well in FIG. 3, the release link 71 is provided with a hook 71b for hooking the spring member 74a on the portion of the T-shaped left arm shown in FIG. As described above, one end portion of the spring member 74a is hooked to the hook portion 32d of the fixing bracket 32, and the other end portion of the spring member 74a is hooked to the hook portion 71b of the release link 71. The release link 71 is elastically held in a normal posture state in which the engaging portion 71a is suspended by the biasing action of the spring member 74a. Further, the release link 71 is provided with a connecting portion 71c that is pin-coupled to the interlocking bracket 72 at the portion that becomes the right arm of the T-shape shown in FIG.
Next, as shown well in FIGS. 3 and 5, the interlocking bracket 72 is formed in a plate shape as a whole, and is connected to the fixed bracket 32 at the same position as the release link 71 (coupling pin P <b> 2). Has been. 5, the interlocking bracket 72 is provided with a hook 72b for hooking the spring member 74b on the upper part of the pin connecting position (the connecting pin P2). One end portion of the spring member 74 b is hooked to the hook portion 32 e of the fixed bracket 32, and the other end portion is hooked to the hook portion 72 b of the interlocking bracket 72. The interlocking bracket 72 is elastically held in the normal posture state in which the interlocking bracket 72 is engaged with the stopper portion 32b described above by the biasing action of the spring member 74b. Further, the interlocking bracket 72 is formed with an arc-shaped escape hole 72 b at a portion connected to the connecting portion 71 c of the release link 71. The escape hole 72b has a shape that causes the connecting portion 71c to escape along an arc shape and idle when the release link 71 is rotated counterclockwise from the normal posture state shown by the two-dot chain line in FIG. ing. Further, when the release link 71 is rotated clockwise from the normal posture state, the connecting portion 71c is positioned at the extreme end portion of the arc shape, and the interlocking bracket 72 is actuated so as to be interlocked clockwise and pulled down. To do. That is, the escape hole 72b acts to interlock the interlocking bracket 72 only when the release link 71 is rotated clockwise. In addition, a protrusion-shaped pushing portion 72c is formed at the turning end portion of the interlock bracket 72.
Next, as shown in FIGS. 3 and 6, the removal link 73 is formed in a shape in which a plate-shaped member forms an L shape, and this L-shaped connecting portion is attached to the fixing bracket 32. It is pin-coupled (coupling pin P3). As shown in FIG. 6, the removal link 73 is disposed as a position that is pushed and rotated by the pushing portion 72 c of the interlocking bracket 72. Then, along with this rotation, the above-described stopper plate 52 is engaged with the stopper pin 52 by pushing the proxy plate 51a of the hook 51, and the hook 51 is removed from the stopper pin 52. Specifically, as shown well in FIG. 6, the removal link 73 has an L-shaped left arm portion shown in FIG. 6 with a length that is pushed by the pushing portion 72c. A portion 73a is formed. In addition, an L-shaped right arm portion shown in the figure is formed with an external portion 73b whose tip portion protrudes in the thickness direction (see FIGS. 3 and 5). As shown well in FIG. 5, the extracted outside 73 b is formed to have a thickness shape that can be engaged with a substitute plate 51 a that is spaced apart in the thickness direction of the extracted link 73. Yes. Further, the pin coupling position (coupling pin P3) of the removal link 73 is in a normal posture state (position state indicated by a two-dot chain line in FIG. 6) where the removal link 73 does not interfere with the substitute plate 51a of the hook 51. A spring member 74c (see FIG. 5) that is urged to rotate is provided.

Subsequently, as a method of using the vehicle seat according to the present embodiment, a method of placing the seat 1 in the retracted state in a state in which the seat 1 is slid to a rear avoidance position that does not interfere with the tire house H will be described.
First, as shown well in FIG. 2, in a normal posture state where the seat cushion 3 is lying on the floor F, the lock portions 21 a and 21 b of the cushion lock 20, the lock portion (not shown) of the slide mechanism 60, and reclining The lock portions (not shown) of the mechanism 10 are in a locked state.
Therefore, first, the release lever L is released. Thereby, the locked state of the reclining mechanism 10 is released, and the seat 1 is in a state where the seat back 2 is folded toward the seat cushion 3 (position indicated by a two-dot chain line in FIG. 1). Next, the locked state of the cushion lock 20 is released. As a result, the seat 1 receives a rotation biasing force by the action of the torsion spring member 40 and rotates in the standing direction from the position in the normal posture state. Specifically, as shown in FIG. 4, the seat 1 is urged and rotated around the hinge pin 33 of the hinge mechanism 30. With this operation, the hook 51 connected to the rotating bracket 31 of the hinge mechanism 30 moves upward and engages and locks with the stopper pin 52. Thereby, the energizing rotation of the seat 1 is regulated at the rotation angle position (position indicated by the solid line in FIG. 4) before the interference with the tire house H, and is held at this rotation angle position.
Next, as well shown in FIG. 5, the seat 1 held at the angular position in the middle of the rotation is slid toward the rear of the vehicle. At this time, when the sheet 1 is slid, the sheet 1 is always held at the angular position, so that it is only necessary to apply a force in the direction of sliding without supporting the sheet 1. When the slide position of the seat 1 passes through a rear avoidance position where the seat 1 does not interfere with the tire house H (a position indicated by a solid line in the figure), the release link 71 of the release mechanism 70 is hooked on the slide rail 61. It engages with the overhanging part 62a of the part 62 and rotates. Specifically, the release link 71 rotates in the clockwise direction shown in FIG. Thereby, the interlocking bracket 72 rotates in conjunction with the release link 71 and pushes down the pushed portion 73 a of the removal link 73. As shown in FIG. 6, the removal link 73 is rotated by the above-described depression, and pushes the substitute plate 51 a of the hook 51 in the locked state with the stopper pin 52. As a result, the hook 51 is removed from the stopper pin 52, and the engagement lock state of the engagement lock mechanism 50 is released. Then, the seat 1 is urged and rotated in the standing direction as it is by the rotating urging force of the torsion spring member 40, and is placed in the retracted position at the side wall W at the rear avoidance position that does not interfere with the tire house H (FIG. 1).
As shown well in FIG. 1, the seat 1 in the retracted state is formed by engaging a holding belt B attached to a portion such as a seat cushion 3 with an assist grip G on the side wall W, for example. The stored state can be stably maintained.

As described above, according to the vehicle seat of the present embodiment, a series of operations in which the seat 1 is slid and moved to a rear avoidance position that does not interfere with the tire house H that is an obstacle can be easily performed. It can be carried out. Further, even when the seat 1 is to be stored at a position where it interferes with the tire house H, the latching lock mechanism 50 is operated, so that the storage operation at such an inappropriate position cannot be performed. Therefore, it is possible to prevent an erroneous operation when the sheet 1 is stored.
In addition, since the engagement lock state by the engagement lock mechanism 50 can be automatically released by sliding the seat 1 to the rear avoidance position that does not interfere with the tire house H, such an operation can be omitted. Is preferred.
Further, the torsion spring member 40, the engagement lock mechanism 50, and the release mechanism 70 that constitute the storage mechanism for putting the seat 1 into the storage state are each assembled to the hinge mechanism 30. There is no obstruction when using the seat 1. That is, such a configuration can be suppressed in a compact manner, which is preferable.

Although the embodiment of the present invention has been described with respect to one example, the present invention can be implemented in various forms other than the above-described embodiment.
First, the tire house H having a shape protruding from the floor F is illustrated as an obstacle that interferes during the storing operation of the seat 1, but it goes without saying that other obstacles may be used.
Further, although the release lever L is shown connected to the lock part of the reclining mechanism 10, the lock parts 21a and 21b of the cushion lock 20, and the lock part of the slide mechanism 60, it is not necessarily connected to all of these configurations. It does not have to be. For example, a release lever for the reclining mechanism may be provided separately, and the release operation may be performed separately. Note that the release lever L is of a rotation operation type, but may be of a push-pull operation type, for example.
In addition, although the release mechanism 70 pushes the proxy plate 51a of the hook 51 to release the engagement lock state, the release mechanism 70 directly releases the hook to release it. There may be. However, in this case, it is necessary to appropriately set the length dimension of each part and the shape of the pushing surface so that the hook can be pushed smoothly.

It is the figure showing the state which stored the vehicle seat of the present Example in the position of the side wall. It is a figure showing the support structure of the vehicle seat. It is the figure which expanded and represented the structure around a hinge mechanism in FIG. It is a figure showing operation | movement of a latching lock mechanism. It is a figure showing operation when sliding a vehicle seat to an avoidance position. It is a figure showing operation | movement of the latching locking mechanism corresponding to FIG.
