Description

  The present invention relates to a vehicle seat structure. Specifically, a vehicle seat capable of accommodating a first seat serving as a seating portion disposed on the floor of the vehicle in a lower space of the second seat disposed behind or in front of the first seat. Concerning structure.

Conventionally, in a seat structure in which three rows of seats are disposed in a vehicle interior, the second row seats can be folded and accommodated in the lower space of the third row seats. Here, Patent Document 1 below discloses a technique in which a second row sheet is slid rearward to be accommodated in a lower space of the third row sheet. In this disclosure, both the second row seat and the third row seat are configured to have a horizontally long width that can be seated by two to three people. Accordingly, in order to accommodate such a horizontally long second row sheet, a horizontally long lower space corresponding to this is formed in the third row sheet.
Japanese Patent Laid-Open No. 5-286384

  However, in the related art disclosed above, since the lower space is formed in the third row seat, the support strength of the third row seat with respect to the floor is likely to be insufficient.

  The present invention was devised to solve the above-described problems, and the problem to be solved by the present invention is to form a space in the lower portion of the second sheet that can accommodate the first sheet. It is to be able to ensure the supporting strength of the second sheet with respect to the floor.

In order to solve the above problems, the vehicle seat structure of the present invention takes the following means.
First, according to a first aspect of the present invention, a first seat serving as a seating portion disposed on a vehicle floor is accommodated in a lower space of a second seat disposed at a rear or front position of the first seat. This is a vehicle seat structure that can be used. The first seat is accommodated in the lower space of the second seat in a folded posture in which the seat back is tilted forward to the upper surface of the seat cushion. In the lower space of the second sheet, a reinforcing structure capable of taking a reinforcing posture capable of supporting the second sheet from the lower side with respect to the floor is disposed. This reinforcing structure is retracted so that the first sheet can be allowed to enter the lower space. In a state where the first sheet enters the lower space and the reinforcing structure is retracted, the first sheet takes a reinforcing posture capable of supporting the second sheet from the lower side with respect to the floor in the lower space. Yes.

  According to the first aspect of the present invention, the reinforcing structure is disposed in a reinforcing posture in the lower space before the first sheet is accommodated in the lower space of the second sheet. Thereby, the 2nd sheet will be in the state where it was supported and reinforced by the reinforcement structure from the lower side to the floor. The first sheet can be accommodated in the lower space by retreating the reinforcing structure in the lower space of the second sheet. As a result, the reinforcing state of the second sheet by the reinforcing structure is released, but instead, the first sheet that has entered the lower space of the second sheet can support the second sheet from the lower side with respect to the floor. Take. Therefore, the support strength with respect to the floor of a 2nd sheet | seat can be ensured by this 1st sheet | seat.

Next, according to a second aspect, in the first aspect described above, the reinforcing structure is held so as to always take a reinforcing posture capable of supporting the second sheet by urging. And the reinforcement structure is pushed away against the urging | biasing by the motion which a 1st sheet | seat enters in lower space.
According to the second aspect of the invention, the reinforcing structure is pushed away by the movement of accommodating the first sheet in the lower space of the second sheet. Then, the reinforcing structure is returned to the reinforcing posture state in which the second sheet can be supported by the urging by the movement of the first sheet to the outside from the lower space of the second sheet.

  Next, according to a third aspect, in the first or second aspect described above, the first seat is slid to a position in the lower space of the second seat between the first seat and the vehicle floor. And a tilt device capable of dropping the seating height position of the first seat with respect to the slider device by the link motion of the four-bar linkage mechanism. The first sheet is accommodated in the lower space of the second sheet by the operation of the slider device in a posture state in which the first sheet is dropped onto the floor by the operation of the tilt device. Between the first sheet and the slider device, there is a function as a stopper for restricting the drop movement of the first sheet by contact, and the downward load applied to the first sheet is directly applied to the constituent members of the slider device. A transmission structure capable of transmitting is set.

  According to the third aspect, the movement of the first sheet dropped onto the floor by the operation of the tilt device is restricted by the contact of the transmission structure set between the first sheet and the slider device. As a result, the first sheet in the posture dropped onto the floor has a support structure in which the downward load is directly transmitted to the constituent members of the slider device by the transmission structure. Therefore, when the first sheet is accommodated in the lower space of the second sheet, the support structure that can support the second sheet from the lower side is exhibited by the support structure via the transmission structure of the first sheet.

  Embodiments of the best mode for carrying out the present invention will be described below with reference to the drawings.

  First, the vehicle seat structure of the first embodiment will be described with reference to FIGS. Here, in FIG. 1, the seat structure of the vehicle of the present embodiment is shown in a side view. As shown in the figure, on the vehicle floor F, a second seat 20 serving as a second-row seat of the vehicle and a third seat 30 serving as a third-row seat are arranged side by side in the longitudinal direction of the vehicle. Yes. Here, the second sheet 20 corresponds to the first sheet of the present invention, and the third sheet 30 corresponds to the second sheet of the present invention. Although not shown, a front seat serving as a driver seat and a passenger seat is disposed on the front row side of the second seat 20.

  Among these, the second seat 20 disposed on the front row side in the figure has a horizontally long width that can seat two to three seaters seated in this row. And the 3rd sheet | seat 30 arrange | positioned in the row | line | column of the back is also the structure which had the width of the horizontally long shape which can seat all the 2 to 3 seated persons seated in this row | line | column. . In the seat structure of the present embodiment, as shown in FIG. 2, the second seat 20 on the front row side is folded and switched to the position where it is dropped onto the floor F, so that the entire second seat 20 is replaced with the third seat on the rear row side. It can be slid and accommodated in an accommodation space 34 formed under the seat 30. Here, the accommodation space 34 corresponds to the lower space of the present invention.

  Therefore, the third seat 30 has a configuration in which the supporting strength with respect to the floor F is likely to be insufficient due to the vacant configuration having the accommodation space 34. Therefore, as shown in FIG. 1, a reinforcing structure 1 that can take a reinforcing posture capable of supporting the third sheet 30 from the lower side with respect to the floor F is provided in the accommodation space 34 below the third sheet 30. It is arranged. The reinforcing structure 1 is provided with the lower end portion thereof connected to the floor F, and is standing upright that can support the third seat 30 from below by the biasing before the second seat 20 enters the accommodation space 34. It is held in a posture state.

  Then, as shown in FIG. 2, the reinforcing structure 1 is pushed away by the second seat 20 by the movement of the second seat 20 into the accommodating space 34 and switched to the lying posture state. Therefore, the retraction structure of the reinforcing structure 1 allows the movement of the second seat 20 into the accommodation space 34. And the accommodation state of the third sheet | seat 30 by the reinforcement structure 1 is released by accommodation of this second sheet | seat 20. FIG. However, instead, the second seat 20 entering the accommodation space 34 takes a reinforcing posture capable of supporting the third seat 30 from the lower side with respect to the floor F. Thereby, the support strength with respect to the floor F of the 3rd sheet | seat 30 is ensured.

  Next, the configuration of the second sheet 20 will be described in detail. The second seat 20 includes a seat back 21 that serves as a backrest and a seat cushion 22 that serves as a seating portion. The seat back 21 is connected to the rear end of the seat cushion 22 via the reclining device 23 at the lower ends of both sides thereof. As a result, the seat back 21 is fixed to the posture position in which the seat reclining device 23 stands up with respect to the seat cushion 22 by switching the reclining device 23 between the locked state and the released state, or the fixed state is released and the upper surface of the seat cushion 22 is released. It has come to be moved forward to the department.

  Note that the basic configuration of the reclining device 23 is a known configuration disclosed in a document such as Japanese Patent Application Laid-Open No. 2002-360368, and a detailed description thereof will be omitted. The operation of releasing the locked state of the reclining device 23 is performed by an operation of depressing the operation lever 21A provided at the shoulder opening of the seat back 21. Here, as shown in FIG. 3, the operation lever 21 </ b> A is provided at the position of both shoulder openings of the seat back 21, and is arranged so as to protrude upward from the upper surface of the seat back 21. And these operation levers 21A will release the locked state of the reclining apparatus 23 by performing the pushing-down operation which rotates either one to the width direction outer side (outer side or inner side) of the seat back 21. ing.

  Here, the reclining device 23 is urged in the operation direction that is normally locked. Although not shown, the reclining device 23 is locked against the above urging by operating the operation component connected to the operation lever 21A and the cable by the release operation of the operation lever 21A. The state is to be released. Then, the locked state of the reclining device 23 is released, so that the fixed state of the backrest angle of the seat back 21 is released. As a result, the seat back 21 can be moved forward to the upper surface of the seat cushion 22.

  Although not shown, a spring member that urges the seat back 21 forward is hooked between the seat back 21 and the seat cushion 22. Thus, the seat back 21 is tilted forward to the upper surface portion of the seat cushion 22 by urging by releasing the locked state of the reclining device 23 by the release operation (pressing operation) of the operation lever 21A. . Here, the seat cushion 22 is provided with a pair of left and right slider devices 25 disposed on the floor F via a tilt device 24 including a pair of left and right link arms 24A and 24B arranged in the front-rear direction. Are connected to each other.

  The slider device 25 has a configuration capable of adjusting and moving the seating position of the second seat 20 on the floor F in the front-rear direction. Specifically, the slider device 25 includes a rail-shaped lower rail 25B that is integrally fixed to the floor F, and a rail-shaped rail that is slidably fitted in the rail extending direction with respect to the lower rail 25B. And an upper rail 25A. The lower rail 25B and the upper rail 25A are arranged and formed so that the rail shape extends in the front-rear direction of the vehicle. Specifically, as shown in FIG. 2, the lower rail 25 </ b> B has a length in the front-rear direction in which the second seat 20 can be slid to a position in the accommodation space 34 formed in the lower portion of the third seat 30.

  Here, as shown in FIGS. 6 and 7, the slider device 25 has a through hole H... In which a lock claw 25C provided on the upper rail 25A penetrates the upper rail 25A and the lower rail 25B. It is the structure which regulates the sliding movement of the upper rail 25A with respect to the lower rail 25B. The lock claw 25C is normally urged in the operating direction to enter the through hole H by a biasing force of a spring member (not shown).

  The locking claw 25C is not shown in the figure, but the above-described urging is achieved by the release operation of the operation mechanism that moves in conjunction with the movement of the second seat 20 to be described later in FIG. Therefore, it is removed from the through hole H. Thereby, the restriction | limiting state of the slide movement of the upper rail 25A is maintained in the released state.

  Therefore, the second seat 20 in the posture dropped onto the floor F is slid as it is to the rear of the vehicle, so that the second seat 20 can be accommodated in the accommodation space 34 below the third seat 30. The above-described through holes H are formed over a wide range in the longitudinal direction of the lower rail 25B. Thereby, the sliding movement of the upper rail 25A can be regulated in a wide range in the front-rear direction of the lower rail 25B.

  As shown in FIG. 5, for the above-described upper rails 25 </ b> A, the pair of left and right link arms 24 </ b> A described above are attached to the side plate portions of the L-shaped bracket L fixedly installed on the upper surface portions thereof. Each lower end of 24B is pivotally connected so as to be rotatable. The upper ends of the link arms 24A and 24B are pivotally coupled to the side plate portion of the cushion frame 22F that forms the skeleton of the seat cushion 22 so as to be rotatable. Accordingly, as shown in FIG. 1, the seating height position of the seat cushion 22 can be changed between the seat cushion 22 and the upper rail 25A as the link arms 24A and 24B are turned up and down. A knot link mechanism is configured.

  The above-described link arms 24A, 24B change the position between the use position where the seat cushion 22 is seated and used and the fall position dropped on the floor F by its up-and-down rotation. The link arms 24A and 24B are turned up and down by a locking operation of a rotation stopper (not shown) provided at the upper end connecting portion of each link arm 24A on the front side when the seat cushion 22 is in the illustrated seating use position. It is supposed to be locked.

  Here, the basic configuration of the above-described rotation locking device is substantially the same as the above-described reclining device 23. That is, the rotation retaining device also fixes the link arms 24A and 24B in the upright posture state by switching between the locked state and the released state, or releases the fixed state so that the entire second seat 20 is floored. It can be dropped onto F. And the operation of releasing the lock state of the rotation securing device can be performed by the operation of depressing the operation lever 21A provided at the shoulder of the seat back 21 described above.

  Specifically, the operation lever 21A first releases the lock state of each reclining device 23 by performing the release operation. Then, the operation lever 21A releases the lock state of each rotation locking device (not shown) by performing a release operation to a position deeper than the rotation position where the lock state of the reclining device 23 is released. Yes. Therefore, when the second seat 20 is in a seatable posture, the release operation of the operation lever 21A is performed, so that the locked state of the reclining device 23 is first released and the seat back 21 is moved forward.

  If the release operation of the operation lever 21A is stopped in this state, the second seat 20 can be held in the folded posture. However, when the operation lever 21A is released to a deep position again from this state, the locked state of the rotation retaining device is released. Thereby, the entire second seat 20 in the folded posture state is dropped onto the floor F. At this time, the movement of the second seat 20 being dropped onto the floor F is restricted at a position where each stopper 26 fixedly installed on the upper surface of each upper rail 25A comes into contact with the cushion frame 22F. Here, the stopper 26 corresponds to the transmission structure of the present invention.

  As shown in FIG. 5, these stoppers 26 are integrally fixed and installed on the upper surface portion of each upper rail 25 </ b> A described above. These stoppers 26 may be deformed or damaged even when the second sheet 20 receives a force that is pressed downward by a relatively large force in a state in which the sinking of the second sheet 20 is restricted by the contact thereof. It has a configuration with no rigidity and strength.

  Therefore, the downward load applied to the second seat 20 is directly transmitted from the cushion frame 22F to the slider device 25 fixedly installed on the floor F by the stoppers 26 without using the link arms 24A and 24B. Is done. Therefore, the load applied to each link arm 24A, 24B can be reduced compared to the configuration in which the sinking of the second seat 20 is regulated by contact with each link arm 24A, 24B, and the second seat can be reduced. 20 can be supported from the lower side with a stable and strong supporting force.

  Next, returning to FIG. 3, the third sheet 30 will be described. The third seat 30 also includes a seat back 31 that serves as a backrest and a seat cushion 32 that serves as a seating portion. The third seat 30 is fixedly supported on the floor F by a support 33 provided at the lower portion of the seat cushion 32. The support 33 is constituted by a side frame 33A assembled in a frame shape standing on both sides under the seat cushion 32, and a top plate 33B connecting the both side frames 33A.

  The top plate 33B is integrally coupled to a frame (not shown) that forms the skeleton of the seat cushion 32. Thus, a space surrounded by the side frames 33A and the top plate 33B is formed as a housing space 34 that opens in the vehicle front-rear direction. The accommodating space 34 is formed in a size that allows the second seat 20 in the folded posture state described above to be accommodated therein. As shown in FIG. 1, the reinforcing structure 1 for reinforcing the support strength of the third sheet 30 described above is disposed in the accommodation space 34.

  The reinforcing structure 1 includes a front frame 2 that is arm-shaped in a side view, a rear frame 3, and a connecting arm 4 that connects these upper end sides. Specifically, as shown in FIG. 4, the front frame 2 is formed in a gate shape when viewed from the front. And the lower end part of the both legs of the front frame 2 is pivotally connected with respect to the floor F by the connection pin 7A. Returning to FIG. 1, the rear frame 3 is also formed in a gate shape in a front view like the front frame 2 although the illustration is omitted. The rear frame 3 is also pivotally connected to the floor F at the lower ends of both legs by a connecting pin 7B.

  The front frame 2 and the rear frame 3 are connected to each other by connecting arms 4 at the upper ends of both legs. Specifically, the connecting arm 4 is pivotally connected to the front frame 2 at its left end in the figure by a connecting pin 7C. The right end of the connecting arm 4 is pivotally connected to the rear frame 3 by a connecting pin 7D. As a result, the reinforcing structure 1 is configured as a four-bar linkage mechanism in which the front frame 2 and the rear frame 3 rotate up and down in conjunction with each other.

  The reinforcing structure 1 always rotates the front frame 2 and the rear frame 3 counterclockwise by the urging force of the tension spring 5 hooked between the lower end portion of the rear frame 3 and the floor F. Is actively energized. The rotation of the front frame 2 and the rear frame 3 by the urging force is restricted at a position where the lower end portion of the front frame 2 contacts the stopper 6 fixed to the floor F. Accordingly, the reinforcing structure 1 is held in a posture position in which the front frame 2 and the rear frame 3 stand up with respect to the floor F at all times before the second seat 20 enters the accommodation space 34.

  And in the attitude | position state in which this reinforcement structure 1 stood, the reinforcement structure 1 will be in the state which supported the top plate 33B of the support body 33 with respect to the floor F from the downward side. As a result, for example, a load that the third seat 30 tends to sink greatly downward due to a bounce when a vehicle collision occurs is supported by the reinforcing structure 1 from the lower side. However, as shown in FIG. 2, the reinforcing structure 1 is pushed back and pushed down by the movement of the second seat 20 entering the accommodation space 34 under the third seat 30.

  The retraction movement structure of the reinforcing structure 1 allows the second sheet 20 to move into the accommodation space 34. However, when the second sheet 20 enters the accommodation space 34, the reinforcing state of the third sheet 30 by the reinforcing structure 1 described above is released. However, when the second sheet 20 enters the accommodation space 34, the second sheet 20 can support the third sheet 30 from the lower side instead of the reinforcing structure 1.

  Specifically, as shown in FIG. 5, the second seat 20 is in a state in which the back portion of the seat back 21 in the folded posture is positioned below the top plate 33 </ b> B of the third seat 30. Thereby, the downward load applied to the third seat 30 is received from the lower side by the back portion of the seat back 21 of the second seat 20. Specifically, the downward load applied to the second seat 20 is received and supported by a stopper 26 provided between the cushion frame 22F and the slider device 25.

  As described above, according to the vehicle seat structure of the present embodiment, the second seat 20 is accommodated and moved into the accommodation space 34 of the third seat 30, so that the reinforcing structure 1 in the accommodation space 34 is retreated. be able to. As a result, the reinforcing state of the third sheet 30 by the reinforcing structure 1 is released, but instead, the second seat 20 that has entered the accommodation space 34 has a reinforcing posture capable of supporting the third sheet 30 from the lower side with respect to the floor F. Take. Therefore, the second sheet 20 can ensure the supporting strength of the third sheet 30 with respect to the floor F.

  Next, the vehicle seat structure of the second embodiment will be described with reference to FIG. In the present embodiment, portions that are substantially the same in configuration and operation as the vehicle seat structure described in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different portions are described in detail. .

  In the present embodiment, a reinforcing structure 40 having two cylinder-type viscous dampers 41 and 42 is disposed in an accommodation space 34 formed under the third sheet 30. Although not shown, the reinforcing structures 40 are disposed in pairs on the left and right sides under the third seat 30. More specifically, the upper ends of the respective viscous dampers 41 and 42 are hingedly connected to each other by a connecting end 43A. And this connection end part 43A is engage | inserted by the rail 33R extended in the front-back direction formed in the upper frame inner surface of the side frame 33A of the support body 33 so that a slide movement is possible.

  And the lower end part of the viscous damper 41 arrange | positioned at the front side is turnable with respect to the rail 33R extended in the front-back direction formed in the lower frame inner surface of the side frame 33A by the connection end part 43B, and slide-moves. It has been fitted. Moreover, the lower end part of the viscous damper 42 arrange | positioned at the rear side is pivotally connected by the connection end part 43C so that rotation with respect to the lower frame of the side frame 33A is possible.

  Although the illustration of the reinforcing structure 40 having the above configuration is omitted, the connection ends 43A and 43B are moved forward by the biasing force of a spring member (not shown) at all times before the second seat 20 enters the accommodating space 34. It is held in an open posture after sliding. As a result, for example, if the third seat 30 tends to sink greatly downward at a high speed due to the bounce when a vehicle collision occurs, the acting force in the contraction direction is applied to the viscous dampers 41 and 42, and the viscous resistance against these contraction movements. The third sheet 30 is supported from below by the action of force.

  And although illustration is abbreviate | omitted, this reinforcement structure 40 is pushed away to the back side by the movement which the 2nd sheet | seat 20 enters in the accommodation space 34. FIG. Specifically, when the viscous damper 41 on the front side is pressed rearward by the second seat 20, the connecting end portions 43 </ b> A and 43 </ b> B slide and move rearward, and the viscous dampers 41 and 42 contract and move. However, it will be in the standing posture state gathered to the rear side. Therefore, the retracting movement of the reinforcing structure 40 allows the second sheet 20 to be accommodated.

Although the embodiment of the present invention has been described with reference to two examples, the present invention can be implemented in various forms in addition to the above-described example.
For example, the second seat (first seat) and the third seat (second seat) may be separately formed in a shape for seating each seated person.
Further, the spring biasing that biases the reinforcing structure to the reinforcing posture may not be provided. That is, the reinforcing structure may be configured to be retracted and moved to a position that does not hinder the accommodation of the second sheet by manual operation when the second sheet is accommodated.
Further, the transmission structure as a stopper set in the second seat (first seat) may be provided on the cushion frame side instead of the slider device side.
Further, the first sheet may be set as a third sheet, and the second sheet may be set as a second sheet. In other words, the first sheet to be accommodated and the second sheet to be accommodated only have to be arranged side by side with each other, and the arrangement position is not particularly limited.
