Abstract

<P>PROBLEM TO BE SOLVED: To prevent careless seating on a seat not located at a seating position. <P>SOLUTION: A front passenger seat 4 movable in the longitudinal direction can be located at a storage position existing largely frontward in addition to a seating guaranteed range to be generally used for an occupant to be seated. In the seating guaranteed range, a locking member 53 is put in engagement with one of a plurality of locked holes 54 formed in the longitudinal direction, thereby restricting the longitudinal movement. The unlocking of the locking member 53 is carried out by an operation member 55. The frontward movement of the seat 4 from the seating guaranteed range to the storage position is restricted by the abutment of a locking member 64 on a locked member 61. The unlocking of the locking member 64 is carried out by the frontward tilting of a seatback 11 of the seat 4. It is also acceptable to construct the seatback 11 to be automatically tilted frontward in linkage with the frontward movement of the seat 4 from the seating guaranteed range to the storage position. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat storage structure.

[0002]

2. Description of the Related Art Generally, in addition to a driver's seat, a passenger's seat is disposed on the side of the driver's seat behind the instrument panel arranged in the front of the passenger compartment. In many cases, a rear seat is arranged in the vehicle compartment behind the driver seat and the passenger seat. Then, not only the seat, especially the driver's seat, but also the passenger's seat can be moved in the front-rear direction by the slide mechanism, and can be restricted (locked) at the desired front-rear position by the restricting means. It is common to have

In many cases, the passenger seat is not used, that is, the passenger does not need to sit on the passenger seat. In this way, when the passenger seat is not used, the passenger seat should be set farther forward than the normal use range in which the occupant is seated so that the passenger compartment space behind the passenger seat can be used as effectively as possible. It has been proposed that the storage position be moved to (for example, Japanese Patent Laid-Open No. 2000-23).
(See Japanese Patent No. 8560).

[0004]

As described above, when the passenger seat is moved to the front by a distance larger than the normal use range so that the passenger can take the stowed position, the passenger seat at the stowed position is It is not expected that the occupant will be seated, and it will be an unfavorable safety situation. Therefore, some measure that can prevent the passenger from inadvertently sitting on the passenger seat in the storage position is desired. Things like this
The same applies not only to the case where the seat is the passenger seat, but also to the driver seat and the rear seat which can be set to the storage position which is located forward and larger than the normal use range.

The present invention has been made in consideration of the above circumstances, and an object thereof is to prevent a situation in which an occupant inadvertently sits on a seat in a storage position which has been largely moved forward. To provide a preferable seat storage structure for a vehicle.

[0006]

In order to achieve the above object, the present invention has the following as a first solution. That is, as described in claim 1 in the claims, in a vehicle seat storage structure in which a seat is provided behind an instrument panel provided in a front portion of a vehicle compartment, the seat is a seat cushion, The seat cushion includes a seat back connected to a rear end portion of the seat cushion so as to be swingable in the front-rear direction, and a headrest provided at an upper end portion of the seat back. It is possible to move in any direction,
In addition to the forward / backward movement within the guaranteed seating range that is normally used by an occupant, it is also possible to move to a storage position that is a position further forward than the guaranteed seating range. There is provided a first restricting means for restricting the movement in the direction and a second restricting means for restricting the movement of the seat from the seating guarantee range toward the storage position. According to the above solution method, when the occupant seated on the seat adjusts the front-rear position of the seat within the guaranteed seating range, the desired front-rear position is obtained while the restriction of the first restricting means is released. Sometimes again
The regulation state may be set by the regulation means (the same as the normal front-back position adjustment of the seat). When the passenger is in the stowed position, the occupant must intentionally perform the operation of releasing the restriction of the second restricting means, so that the seat can be sufficiently recognized that the seat is in the stowed position. This is preferable for preventing a situation where the user is inadvertently set to the storage position while seated.

A preferred mode on the premise of the first solution method is as follows. The restriction release of the first restriction unit and the restriction release of the second restriction unit may be set to be performed by different operations (corresponding to claim 2). In this case, the restriction release of the second restricting means needs to be performed by a different operation from the restriction release of the first restricting means. Can be recognized.

It is possible to release the restriction of the second restricting means only when the seat is in a seating prevention state in which an occupant cannot sit down (corresponding to claim 3). In this case, since the seat can be moved to the storage position only when the passenger cannot sit, it is possible to reliably prevent the passenger from sitting on the seat in the storage position.

In order to achieve the above-mentioned object, the present invention has the following second solution. That is, as described in claim 4 in the claims, in a vehicle seat storage structure in which a seat is provided behind an instrument panel provided in a front portion of a vehicle compartment, the seat is a seat cushion, The seat cushion includes a seat back connected to a rear end portion of the seat cushion so as to be swingable in the front-rear direction, and a headrest provided at an upper end portion of the seat back. The seat can be moved in any direction, and can be moved forward and backward within a seating guarantee range that is normally used by an occupant when seated, and can also be moved to a storage position that is a position further forward than the seating guarantee range. When the seat is in the storage position, seating prevention means is provided to bring the seat into a seating prevention state in which an occupant cannot sit. According to the above solution method, since the occupant cannot sit when the seat is in the storage position, it is possible to reliably prevent the occupant from seating in the seat in the storage position.

A preferred mode based on the above solution method is as follows. The seating prevention means may be set so as to automatically enter the seating prevention state in conjunction with the movement of the seat from the seating guarantee range toward the storage position (claim). Item 5). In this case, the occupant is automatically changed to a state in which the seat cannot be seated as the seat moves toward the storage position, which is extremely preferable in preventing the seat occupant from sitting in the storage position.

The seating prevention state may be such that the seat back is tilted forward (corresponding to claim 6). In this case, the seating prevention state can be easily obtained by utilizing the forward tilting of the seat back.

On the premise of each of the above solving methods, the following can be performed. A recess is formed in the upper surface of the front portion of the seat of the instrument panel,
When the seat back is tilted forward when the seat is in the storage position, a part of the seat is stored in the recess, and an upper end of the seat and an upper surface of the instrument panel are substantially formed. It can be made flush (corresponding to claim 7). In this case, it is preferable to store a part of the seat in the recess so as to maximize the rear space of the seat at the storage position. Further, since the upper surface of the instrument panel and the upper end portion of the sheet are substantially flush with each other in a state where a part of the sheet is housed in the recess, the appearance is also good.

It is possible that only the headrest of the seat is accommodated in the recess (corresponding to claim 8). In this case, it is not necessary to make the recess extremely large.

The seat may be a passenger seat arranged laterally of the driver seat (corresponding to claim 9). In this case, the rear space of the passenger seat in the storage position can be expanded.

A rear seat can be arranged at least behind the passenger seat (corresponding to claim 10). In this case, the large rear space of the passenger seat in the storage position can be effectively used for the passenger in the rear seat.

In order to achieve the above object, the present invention is as follows as a third solution. That is,
As described in claim 11 in the claims, in a vehicle seat storage structure in which a passenger seat is provided behind an instrument panel provided in a front portion of a vehicle compartment, the passenger seat is A seat cushion, a seat back connected to a rear end portion of the seat cushion so as to be swingable in the front-rear direction, and a headrest provided at an upper end portion of the seat back, and the passenger seat includes: By the slide mechanism, the seat cushion can be largely moved in the front-rear direction, and in the state in which the seat cushion is moved to the frontmost position, at least the front end portion of the seat cushion can be in the retracted position under the instrument panel. A first position that restricts the front-back movement of the seat in a range behind a specific position that is set and is a predetermined amount behind the storage position. Regulating means are provided, said first
It is possible to provide a second restricting unit that is provided separately from the restricting unit and that restricts the movement of the sheet from the specific position to the storage position. As a result, the same effect as that of the first aspect can be obtained.

A preferred mode based on the above solution method is as follows. It is possible to set that the restriction release of the first restricting means and the restriction release of the second restricting means are set to be performed by different operations (corresponding to claim 12). In this case, the same effect as that of the second aspect can be obtained.

When the passenger seat is in the storage position and the seat back is tilted forward, at least a recess for accommodating the headrest is formed in the instrument panel. It is possible (corresponding to claim 13). In this case, the rear space of the seat in the storage position can be expanded because the seat in the storage position is partially accommodated in the recess.

[0019]

According to the present invention, it is preferable for preventing the situation where the occupant is inadvertently seated on the seat in the storage position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 3, reference numeral 1 denotes an instrument panel, which is arranged in the front part of a vehicle compartment 2 and extends long in the vehicle width direction. In the passenger compartment 2, behind the instrument panel 1, a driver's seat 3 (see FIG. 2) as a front seat and a passenger's seat 4 are arranged at intervals in the vehicle width direction. . In the passenger compartment 2, a rear seat 5 is provided behind the seats 3 and 4 as front seats. Rear seat 5
Is a bench type that extends over almost the entire length in the vehicle width direction, for example.

In the embodiment, the passenger seat 4 is a seat that can be stored in a storage position described later. The passenger seat 4 will be described below. First, as is known, the passenger seat 4 has a seat cushion 10, a seat back 11 connected to a rear end portion of the seat cushion 10, and a headrest 12 connected to an upper end portion of the seat back 11. . Seat back 1
1 is swingably connected to the seat cushion 10 in the front-rear direction, and can be tilted at least forward from the standing position.

The passenger seat 4 is movable in the front-rear direction. That is, the slide rail 13 extending in the front-rear direction is fixed to the floor panel 6, and the lower portion of the support base 14 fixed to the lower surface of the seat cushion 10 is slidable in the front-rear direction with respect to the slide rail 13. Have been combined. The slide rail 13 and the support base 14 form a slide mechanism.

In FIG. 1, the front passenger seat 4 is moved forward and backward by a greater extent than the guaranteed seating range, which is the range in which the seat seat 4 is allowed to be seated and used. It can take a storage position. The passenger seat 4 located at the rearmost position in the guaranteed seating range is indicated by a one-dot chain line, and the reference hip point at this time is indicated by reference numeral HP1 and the swing fulcrum of the seat back 11 is indicated by reference numeral α1. . The frontmost passenger seat 4 in the guaranteed seating range is indicated by a wavy line, and the reference hip point at this time is indicated by reference sign HP2, and the swing fulcrum of the seat back 11 is indicated by reference sign α2. Further, the passenger seat 4 in the storage position is shown by a solid line, and the reference hip point at this time is shown by reference numeral HP3, and the seatback 11
The rocking fulcrum of is indicated by reference sign α3.

Among the anchors for fixing the seat belt for the passenger seat 4 (three-point type in the embodiment) to the vehicle body side, the anchors located at the lower lateral portions of the passenger seat 4 (usually a pair of left and right are provided). Is indicated by reference numeral 15. The anchor 15 holds each end of the waist belt portion that presses near the waist of the occupant seated on the passenger seat 4.

Explaining the guaranteed seating range, basically, for an occupant sitting on the passenger seat 4,
The waist belt portion is set in a range such that the occupant can be restrained in both the rearward and downward directions. In other words, a range that does not cause excessive rearward restraint (when the downward restraint is insufficient) or excessive downward restraint (when the backward restraint is insufficient). To be done.

The seating guarantee range will be described more specifically. Virtual lines β1 and β connecting the reference hip points HP1, HP2 and HP3 and the mounting portion of the anchor 15 to the vehicle body.
2 and β3 are assumed. The inclination angles of the virtual lines β1, β2, and β3 with respect to the floor panel 6 (horizontal plane) are θ1, θ2, and θ3, respectively. In the guaranteed seating range, the inclination angles θ1 and θ2 are within a predetermined angle range (for example, 25 degrees to 70 degrees).
)) Is set. However, the tilt angle θ3 when the passenger seat 4 is in the storage position moved forward by a distance larger than the guaranteed seating range is outside the predetermined angle range. In the embodiment, the seat 4 for the passenger seat when in the storage position is in a state in which at least the front end portion of the seat cushion 10 is recessed below the instrument panel 1, but the seat cushion 10 is deeper ( It may be moved further (forward) or may be positioned rearward as compared with the case of the embodiment.

1 to 5, a recess 21 is formed in a portion of the instrument panel 1 which corresponds to the front of the passenger seat 4. The recess 21 is opened toward the upper surface of the instrument panel 1 and also toward the rear of the vehicle compartment. The size or shape of the recess 21 corresponds to the size or shape of the headrest 12 of the passenger seat 4 and is slightly larger than the headrest 12.

As particularly shown in FIGS. 2 and 3, the instrument panel 1 holds a steering handle 22 and a shift knob 23, and an operation portion 24 such as an audio device and an air conditioning operation at a substantially middle portion in the vehicle width direction. Part 25 is equipped. A glove box 26 is formed in the instrument panel 1 below the concave portion 21, and an opening / closing lid of the glove box 26 is indicated by reference numeral 26a. Further, an airbag unit 45 for the passenger seat 4 is installed in the instrument panel 1 (see FIGS. 1 and 7).

Inside the instrument panel 1, at an intermediate portion in the vehicle width direction, an air conditioning unit 3 as described later is provided.
0 is equipped. The conditioned air from the air conditioning unit 30 is supplied into the vehicle compartment from various air outlets provided in the instrument panel 1. In the embodiment, there are the following air outlets for conditioned air. First, at the upper position of the approximately middle portion in the vehicle width direction, the air outlet 31 for passengers is provided.
In addition to the above, the air outlet 32 for the occupant is formed at the upper position of each end in the vehicle width direction. At each end in the vehicle width direction, air-conditioning air outlets 33 for preventing the fogging of the side windows are formed. Of course, in addition to the above-described air outlets, the instrument panel 1 is also provided with air outlets to the lower portion of the vehicle compartment, air outlets for preventing the front windshield from clouding, and the like.

The air conditioning unit 30 is formed such that the length in the vehicle width direction is shorter than usual and the length in the front-rear direction is longer than usual (see FIG. 2). Although the portion of the duct 34 that passes through the recess 21 is disposed directly below the recess 21, it may be disposed so as to pass in front of the recess 21.

FIG. 6 shows an example of the air conditioning unit 30. In FIG. 6, reference numeral 36 is a blower chamber in which a blower is arranged, and the air from the blower chamber 36 is once cooled by an evaporator 37. The air that has passed through the evaporator 37 directly flows into the mix chamber 38 while the damper 3
Depending on the switching position of 9, a part of it passes through the heater core 39 and then flows into the mix chamber 38. Mix room 3
Air-conditioning air flows from 8 to each outlet. In FIG. 6, the duct 40 is for the air outlet 31, the duct 41 is for air conditioning air supply toward the lower part of the vehicle compartment, and the duct 42 is for air conditioning air supply toward the front window 7. Further, the duct 43 for the outlet 33 is formed by branching from the duct 42 (see also FIGS. 1 and 7). A damper for opening and closing each duct is not shown. Further, in the embodiment, the air conditioning unit 30 as described above,
The steering wheel 22, the operation parts 24 and 25, the airbag unit 45, and the like are assembled in advance in the instrument panel 1 (modularization) and then assembled in the vehicle body. Further, reference numeral 46 in FIG.
Is a steering support member as a vehicle body strength member that extends over substantially the entire length in the vehicle width direction.

Next, a restricting means for restricting the movement of the passenger seat 4 will be described. First, FIGS. 8 and 9 show a sectional structure of a portion where the support base 14 of the passenger seat 4 is guided in the front-rear direction by the slide rail 13. As shown in FIG. 9, the lock member 53 is slidably held on the support base 14 only in the vertical direction by using the bracket 51 and the holding pin 52. On the other hand, the slide rail 13 has a small pitch (for example, 5 mm) in the front-rear direction.
In each case, a large number of hole-shaped locking portions 54 are formed. The lock member 53 is constantly urged downward by a spring (not shown). When the lock member 53 is engaged with the locking portion 54 as shown in FIG. 9, the forward / backward movement of the passenger seat 4 is restricted. When the engagement with the locking portion 54 is released by displacing the lock member 53 upward from the state of FIG. 9, the passenger seat 4 can move in the front-rear direction (lock release). . The movement restriction of the passenger seat 4 using the lock member 53 and the locking portion 54 and the back-and-forth movement in the deregulated state are performed only within the guaranteed seating range (the passenger seat 4 within the guaranteed seating range).
The locking portion 54 is formed only in the moving range of the lock member 53 when the is moved back and forth).

As shown in FIG. 10, the lock member 53 is provided.
An operation member 55 for releasing the restriction (lock release) is disposed below the seat cushion 10. The operating member 55 is swingably held on the lower surface of the seat cushion 10 via a bracket 56 and a holding pin 57. The operating member 55 is connected to the lock member 53 via a cable 58 (see also FIG. 9).
When the operation portion 55a of the operation member 55 is pulled up by a manual operation, the cable 58 is pulled and the lock member 53 is displaced upward (unlocked). It should be noted that the cable 58 is actually configured by the inner cable of the inner and outer double cables. The lock member 53, the locking portion 54, the operation member 55, the cable 58 as described above.
The first restricting means is configured by the above. The setting position of the lock member 53 is, for example, a portion indicated by an arrow A in FIG.

At the front end portion of the slide rail 13, there is formed only one locking portion 54 with which the locking member 53 is engaged when the passenger seat 4 is in the storage position. That is, when the passenger seat 4 is set to the storage position as described below, the locking member 53 engages with the locking portion 54 at the front end of the slide rail 13 so that the passenger seat 4 is in the storage position. The forward and backward movement of the seat 4 is restricted. As described above, in the embodiment, the lock member 53 for adjusting the front-rear position within the guaranteed seating range is set to be used for restricting the front-rear movement of the passenger seat 4 in the storage position.

The passenger seat 4 is restricted from moving further forward beyond the guaranteed seating range. Therefore, a locking member 61 is integrated with the slide rail 13 as shown in FIGS. On the other hand, a lock member 64 is held on the support base 14 via a bracket 62 and a holding pin 63 so as to be displaceable only in the vertical direction. The lock member 64 is constantly urged downward by a spring (not shown).

The passenger seat 4 within the guaranteed seating range is
When moved forward and moved to the front end position within the guaranteed seating range, the lock member 64 comes into contact with the stopper member 61 from the rear side, and further forward movement of the passenger seat 4 is restricted. (State of FIG. 11 and FIG. 12). When the lock member 64 is displaced upward from this restricted state (locked state), the lock member 64 and the stopper member 61 have a positional relationship in which they do not interfere in the front-rear direction, and the front passenger seat 4 moves further toward the storage position. It becomes possible to move to.

A mechanism for releasing the restriction by bringing the lock member 64 into contact with the stopper member 61 is provided in association with the seat back 11. That is, FIG.
As shown in FIG. 3, the seat bracket 71 provided on the side of the passenger seat 4 has a first bracket portion 71A fixed to the seat cushion 10 and a second bracket portion 71B fixed to the seat back 11. Both bracket portions 71A and 71B are swingably connected by a connecting pin 72. . The connecting pin 72 constitutes a swing fulcrum of the seat back 11. The seat back 11 is constantly urged by a spring (not shown) in a direction in which the seat back 11 tilts forward.

A substantially disk-shaped lock member 73 is integrated with the second bracket portion 71B. This locking member 7
On the outer peripheral surface of 3, there are formed a number of claw-shaped locking portions 74 over a predetermined arc range centered on the connecting pin 72.
On the other hand, the operation member 76 is swingably held by the holding pin 75 on the first bracket portion 71A. A claw-shaped engaging portion 77 that can be engaged with and disengaged from the locking portion 74 is formed at one end of the operating member 76. The operating member 76 is constantly urged by a spring (not shown) in the direction in which the engaging portion 77 engages with the locking portion 74. When the operating portion 76a of the operating member 76 is pulled upward by a manual operation, the engagement of the engaging portion 77 with the locking portion 74 is released, and the seat back 11 can be tilted forward. When the hand is released from the operation portion 76a at the position where the tilt angle of the seat back 11 becomes the desired angle, the engaging portion 77 is again engaged with the locking portion 74 and the desired tilt angle of the seat back 11 is maintained. .

The outer peripheral edge of the lock member 73 and the lock member 64 are connected by a cable 78 (see also FIGS. 11 and 12). As a result, when the seat back 11 tilts forward, the cable 78 is pulled and the lock member 64 is displaced upward. When the seat back 11 is tilted forward by a predetermined angle or more, that is, when it becomes impossible for an occupant to sit on the passenger seat 4, the interference (lock) between the lock member 64 and the stopper member 61 is released. Thus, the passenger seat 4 can be moved forward toward the storage position. In addition, cable 7
8 is actually an inner cable of the inner and outer double cables. The stopper member 61, the lock member 64, the operation member 76, and the cable 78 as described above.
The second restricting means is configured by the above. The setting position of the lock member 64 can be set to an appropriate position such as a position substantially the same as the lock member 53 for the first restricting means or a position apart from the lock member 53.

Next, the usage pattern of the passenger seat 4 will be described by focusing on its front and rear movement. First, when the passenger seat 4 is within the seating guarantee range, the lock member 5 for the locking portion 54 is operated by operating the operation member 55.
When the passenger seat 4 is moved in the front-rear direction with the engagement of 3 disengaged, and the hand is released from the operation member 55 at the desired front-rear position, the passenger seat 4 is held at this position. The forward and backward movement of is restricted.

When the passenger seat 4 within the guaranteed seating range is moved forward to the retracted position, the locking member 64 causes the locking member 64 to stop when the passenger seat 4 reaches the front end position within the guaranteed seating range. By making contact with 61, the forward movement of the passenger seat 4 is restricted.
When the seat back 11 is tilted forward by a predetermined amount or more by operating the operation member 76 from this restricted state,
The contact state between the lock member 64 and the stopper member 61 is released. The passenger seat 4 is moved to the front by a large amount while keeping this released state, so that the passenger seat 4 is set to the storage position. At the storage position, as described above, the lock member 53 is engaged with the engagement portion 54 provided only at the front end of the slide rail 13, and the passenger seat 4 is locked at the storage position. It Note that the passenger seat 4 may be locked at the storage position by using the lock member 64, which is a member on the second restricting means side.

Since the seat back 11 of the passenger seat 4 in the storage position is tilted forward, the occupant cannot sit. Further, by tilting the seat back 11 forward, the headrest 12 is housed in the recess 21 of the instrument panel 1 as shown in FIGS. 1 and 5. When the headrest 12 is housed in the recess 21, the upper surface of the headrest 12 is substantially flush with the upper surface of the instrument panel 1,
The appearance is also good.

A large space is formed behind the passenger seat 4 in the storage position. The large space behind the passenger seat 4 is used for an appropriate purpose, for example, for expanding the leg space of an occupant seated in the rear seat 5, or for storing luggage. . Further, when there is no rear seat 5 behind the passenger seat 4, for example, when the rear space of the driver seat 3 and the passenger seat 4 is set as a luggage compartment, it is in the storage position. A large space behind the passenger seat 4 may be used as an expanded cargo space that communicates with the cargo space behind it.

FIG. 14 shows another embodiment of the present invention. The seat back 11 is interlocked with the front passenger seat 4 moving forward from the guaranteed seating range toward the retracted position.
Is automatically tilted to the front where it becomes unseated automatically. FIG. 14 is a modification of FIG. 13, and the same components as those of FIG. 13 are designated by the same reference numerals and the duplicate description thereof will be omitted. It should be noted that the seat back 11 is always urged forward, and the operation member 76 is always urged in the direction in which the engaging portion 77 is engaged with the locking portion 74. It is similar to the case of 13.

On the premise of the above, the bracket portion 7
An intermediate link 82 is swingably held by a holding pin 81 at 1A. One end of the intermediate link 82 and the vicinity of the engaging portion 77 of the operation member 76 are connected to each other by the connecting link 8
They are connected by 3. The other end of the intermediate link 82 is connected to the upper end of a rod member 84 held by the passenger seat 4 so as to be displaceable only in the vertical direction.

As a result, when the operating member 76 is not operated and no external force acts upward on the lock member 84, the engaging portion 77 of the operating member 76 is locked by the engaging portion 77.
4 is engaged (the tilt angle of the seat back 11 in the front-rear direction cannot be changed). Even when the operating member 76 is not operated, when the rod member 84 is pressed and displaced upward, this displacement causes the engaging portion 77 of the operating member 76 to engage with the locking portion 74 via the intermediate link 82 and the connecting link 83. This is transmitted as the displacement in the direction to release the engagement, and the seat back 11 is tilted forward h (tilting forward by the biasing force described above).

A guide bar 85 extending long forward from the position immediately before the lock member 84 is integrated with the slide rail 13 when the front passenger seat 4 shown in FIG. 14 is at the front end position in the guaranteed seating range. There is. The guide bar 85 constitutes a kind of cam, and when the passenger seat 4 is moved further forward from the front end of the guaranteed seating range, the rod member 84 rides on the upper surface of the guide bar 85, and the rod concerned. The member 84 is displaced upward, whereby the seat back 11 is automatically tilted largely forward. When the passenger seat 4 is in the retracted position (state of FIG. 5), the rod member 84 is engaged with the hole-shaped locking portion 86 opened on the upper surface of the guide bar 85 and is displaced downward again. (The forward / backward movement restriction of the passenger seat 4 at the retracted position).

When the passenger seat 4 in the storage position is moved backward toward the seating guarantee range, first, the operating portion 76a of the operating member 76 is manually pulled up. As a result, the rod member 84 is displaced upward,
The engagement with the locking portion 86 is released, and the passenger seat 4 can be moved backward. By manually returning the seat back 11 to the standing position with the passenger seat 4 retracted to the seating guarantee range, the passenger seat 4 can be seated.

The locking portion 86 may be omitted. In this case, the engaging portion 77 is always disengaged from the locking portion 74 when in the retracted position. In other words, even if the seat back 11 is manually returned to the standing position against the biasing force, the seat back 11 is automatically re-driven automatically by the forward biasing force after the hand is released from the seat back 11. You will be tilted forward.

Although the embodiment has been described above, the present invention is not limited to this, and includes the following cases, for example. The seat that can be stored in the storage position is not limited to the passenger seat and may be the driver seat or the rear seat. Further, the vehicle may not have a rear seat. Further, the lock members 53, 64
Can adopt an appropriate structure for the mechanism for restricting the forward / backward movement of the seat, for example, a structure of swing displacement. Of course, the object of the present invention is not limited to what is specified, and also implicitly includes providing what is expressed as substantially preferable or advantageous.
