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 A vehicle seat usually has a seat cushion, a seat back and a headrest. Behind the instrument panel arranged in the front part of the vehicle compartment, in addition to the driver's seat, a passenger's seat is usually arranged on the side of the driver's seat. 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 to set it to a predetermined position that has been moved to, that is, a storage position (see, for example, JP 2000-238560 A).

On the other hand, in a vehicle, it is general that a plurality of air outlets are provided on the surface of the instrument panel for blowing the conditioned air from the air conditioning unit into the passenger compartment. The positions of the air outlets are set at the substantially central portion of the instrument panel in the vehicle width direction and at each end in the vehicle width direction. In addition to this, there are provided air outlets directed toward the front window and side windows. There are many things.

[0005]

As described above, at the predetermined position where the passenger seat is moved forward more than the normal use range, sufficient expansion of the seat rear space,
It is conceivable to tilt the seat back forward so that the headrest and seat back do not interfere with the visibility and the like. In this case, the air outlet provided on the surface of the instrument panel is covered with the seat back tilted forward, which causes a problem that it becomes difficult to supply the conditioned air to the passenger compartment sufficiently.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a vehicle even when the air outlet provided on the surface of the instrument panel is covered by a seat back tilted forward. It is an object of the present invention to provide a vehicle seat storage structure capable of sufficiently supplying conditioned air into a room.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following means for solving the problem.
That is, as set forth in claim 1 in the claims, a seat is provided behind an instrument panel provided at a front portion of a vehicle compartment, and a surface of the instrument panel is provided with air conditioning air toward the vehicle interior. A first air outlet for blowing out air, and an air conditioning unit and a first duct for supplying air conditioning air from the air conditioning unit to the first air outlet in the instrument panel, The seat has a seat cushion and a seat back having a lower end portion connected to a rear end portion of the seat cushion so as to be swingable in the front-rear direction. The seat back has a second blowout port, and the seatback has a second duct connected to the second blowout port. In a specific state in which the seat back is tilted forward in a state in which the seat is moved forward to a predetermined position, the seat back covers the first outlet and the second duct controls the air conditioning. The air-conditioning air from the air-conditioning unit is communicated with the unit and is set to be blown out from the second outlet. As described above, even if the air outlet provided in the instrument panel is covered by the seat back tilted forward, the conditioned air is supplied from the air outlet provided in the seat back into the vehicle interior instead.

On the premise of the above solution method, the following solution methods can be adopted together. That is, the second outlet is arranged so as to open on the back surface of the seat back, the second duct is formed so as to open on the front surface of the seat back, and the seat is in the specific state. It is possible to be aligned with the first air outlet when being performed (corresponding to claim 2). In this case, the conditioned air that is about to be blown out from the first blowout port can be effectively used as it is and blown out from the second blowout port.

The second outlet is arranged so as to open to the back surface of the seat back, and the other end of the second duct is an end opposite to one end connected to the second outlet. A portion is opened on a side surface of the seat back on the inner side in the vehicle width direction, and the instrument panel is opened toward the outer side in the vehicle width direction at a substantially middle portion in the vehicle width direction, and A third duct communicating with the air conditioning unit is provided, and by bringing the seat into the specific state, the second duct and the third duct are communicated with each other, and the conditioned air is passed through the third duct. It can be provided that it is supplied to the duct (corresponding to claim 3). In this case, by using the third duct separately, it is possible to dispose the second duct formed in the seat back without being restricted by the disposition state of the first duct. In addition, since it is not necessary to open the second duct on the front surface of the seat back, the second duct can be used when it is used as a normal seating use position.
The presence of the air outlet does not make the seated passenger feel uncomfortable.

A headrest is provided at an upper end portion of the seatback, and a recess for accommodating at least the headrest or the upper end portion of the seatback in the specific state is formed in the instrument panel, and the first duct includes: A fixed duct portion which is connected to the air conditioning unit and which is opened in the concave portion, and a fixed duct portion which is arranged so as to pass through the concave portion and is movable with respect to the fixed duct portion, thereby communicating with the fixed duct portion. A movable duct part that is switched between a state and a non-communication state, the movable duct part is in a non-communication state with respect to the fixed duct part, and when the seat is in the specific state,
The second duct may be communicated with the fixed duct portion (corresponding to claim 4). In this case, by storing a part of the seat in the recess, the rear space of the seat can be sufficiently expanded. In addition, the conditioned air can be supplied to the second outlet provided in the seat back by using the first duct as effectively as possible.

The movable duct portion is brought into a non-communication state with the fixed duct portion by being moved by being pressed by the headrest or the seat back upper end portion housed in the recess. It is possible (corresponding to claim 5). In this case, by tilting the seat back forward, the movable duct portion can be automatically brought into a non-communication state with respect to the fixed duct portion.

A part of the instrument panel has a movable panel portion which is moved by being pressed by the seat in the specific state, and the first outlet and the movable duct portion are provided on the movable panel portion. It may be provided (corresponding to claim 6). In this case, by tilting the seat back forward, the movable duct portion can be automatically brought into a non-communication state with respect to the fixed duct portion. Further, the movable duct portion and the first outlet are always integrated with each other, so that the structure for connecting them can be simplified.

In the specific state, the height of the headrest or the seatback upper end portion housed in the recess may be set to be approximately the same as the height of the instrument panel (claim). Item 7).
In this case, it is preferable for sufficiently improving the appearance.

The instrument panel is provided with a lid member that covers the portion of the seat in the specific state, which is accommodated in the recess from above, so as to be openable and closable. When the lid member is in the closed state, the lid member is closed. The surface of the member and the surface of the instrument panel may be substantially flush with each other (corresponding to claim 8). In this case, the appearance of the seat is improved by closing the lid member both when the seat is set to the front predetermined position for expanding the rear space of the seat and when the seat is used for normal seating. Be improved.

In the seat back, an upper portion is bendable forward with respect to a lower portion in a substantially middle portion in the vertical direction,
In the specific state, the upper portion of the seat back is bent forward, the second outlet and the second duct are formed in the upper portion of the seat back, respectively, and the seat back is placed in a normal sitting position. When the upright position is set as follows, the second outlet may be directed substantially downward so as not to be visible from the periphery of the seat back (corresponding to claim 9). In this case, compared with the case where the upper part and the lower part of the seat back are integrated, the seat can be moved further forward as a whole while avoiding the interference between the seat back and the instrument panel, and the rear space of the seat can be reduced. It can be expanded more sufficiently. Also,
In the normal seating use position, the second outlets provided in the seat back are not used, but the unused second outlets are not visible from the outside, which is preferable in appearance.

[0016]

The seat is a passenger seat, and the first outlet is arranged at an end of the instrument panel on the passenger seat side in the vehicle width direction. It is possible (corresponding to claim 10). In this case, when enlarging the space behind the passenger seat, the conditioned air can be supplied into the vehicle compartment from the second outlet provided in the seat back of the passenger seat.

[0018]

According to the present invention, even if the air-conditioning air outlet provided on the instrument panel is covered by the seat back of the seat that has been largely moved forward, the air-conditioning air is sufficiently supplied to the passenger compartment. can do.

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

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.
The member indicated by is a steering support member as a vehicle body strength member that extends over substantially the entire length in the vehicle width direction.

Here, the air outlet 32 arranged at each end of the instrument panel 1 in the vehicle width direction is a first air outlet, and the duct 34 thereof is a first duct. A second duct 47 is formed on the upper part of the seat back 11. The second duct 47 extends substantially in the front-rear direction in the standing position or in a state in which the second duct 47 is tilted slightly forward. The rear end portion 47b is formed on the back surface of the seat back 11. A second outlet 48 is formed at the other end 47b. Such a second duct 47 is formed in the upper part of the seat back 11 and on the outer end side in the vehicle width direction.

In the state where the passenger seat 4 is in the retracted position and the seat back 11 is tilted slightly forward, the seat back 11 covers the first outlet 32 provided in the instrument panel 1. This first outlet 3
With respect to 2, the one end portion 47a of the second duct 47 is adapted to be aligned. As a result, the conditioned air that is about to be blown out from the first blowout port 32 passes through the second duct 47 and is blown out from the second blowout port 48 into the vehicle interior (in particular, refer to FIG. 5). In order to secure the sealing property of the matching portion between the first outlet 32 and the second duct 47, for example, a seal ring made of an elastic member may be provided at the opening edge of the one end 47a of the second duct 47. it can.

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 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 regulation 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 manner of use of the passenger seat 4 will be described by focusing on its forward and backward 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 with the lid member 20 opened in advance, the headrest 12 is housed in the recess 21 of the instrument panel 1 as shown in FIGS. 1 and 5. Become. 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 lid member 20 is closed with the headrest 12 housed in the recess 21. As a result, a part of the seat (the headrest 12 in the embodiment) housed in the recess 21 is covered from above by the lid member 20 so as not to be exposed to the upper surface side of the instrument panel 1. Looks good.

A large space is provided 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. Then, in such a storage position, the seat back 1
Air-conditioning air is supplied to the vehicle compartment from the second outlet 48 provided on the back surface of the vehicle 1.

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 the upward external force does not act on the lock member 84, the engaging portion 77 of the operating member 76 is locked by the engaging portion 7.
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 from the position just before the lock member 84 is integrated with the slide rail 13 in a state where the passenger seat 4 shown in FIG. 14 is at the front end position in the guaranteed seating range. There is.

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 again moves downward. And the vehicle is displaced (restriction of forward / backward movement of the passenger seat 4 at the storage 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.
