Description

  The present invention relates to a vehicle seat including a seat cushion and a seat back, which can be moved between a seating position where an occupant can sit and a loading space position where a loading space can be formed in a vehicle body.

  For example, a vehicle that can be folded to form a luggage compartment for storing luggage or the like between a front row seat and a back door, such as a rear row seat of a hatchback type vehicle having two rows of front and rear rows Seats are known.

  As a vehicle seat of this type, for example, Japanese Patent Laid-Open No. 2005-306357 proposes a so-called folding structure in which the seat back can be turned forward and superimposed on the seat cushion. Further, for example, in Japanese Patent Application Laid-Open No. 2006-21747, after the seat back is turned forward and superimposed on the seat cushion, the front end side of the seat cushion is centered on a pivot axis extending along the vehicle width direction. A so-called double-folding structure has been proposed in which the seat back and the seat cushion can be raised so that the surface direction of the overlapping surface is along the vertical direction.

  When the above-described folding structure is adopted, a loading space is formed above the seatback superimposed on the seat cushion, and the space below the seatback can not be used as the loading space. For this reason, it is difficult to secure a sufficient size in the height direction of the cargo space.

  In addition, when the above-mentioned double folding structure is adopted, a load space is formed between the seat cushion raised in a state where the seat backs are stacked and the back door, and a space in front of the seat cushion is a load space. It can not be used as For this reason, it is difficult to secure a sufficient size in the front-rear direction of the loading space.

  Therefore, for example, a so-called side-bounce folding structure is proposed in Japanese Patent Laid-Open No. 11-208334. In this structure, after the seat back is turned forward and superimposed on the seat cushion, the seat back is overlapped about the pivot axis extending along the front-rear direction between the lower side of the seat cushion and the side door on the rear row side. The seat back and the seat cushion can be flipped up so that the surface direction of the mating surface is along the side door.

  By adopting such a structure, for example, the space between the floor surface and the ceiling surface in the vehicle body and the space between the back door and the front row seat can be used as a loading space. For this reason, it is possible to secure a sufficient size in the height direction and the front-rear direction of the loading space.

  However, in the above-described sideways-bounce type folding structure, in the state where the loading space is formed, the folded vehicle seat is stored at a position along the rear row side door, so the side door is opened and closed. It is difficult to access

  The present invention has been made in consideration of such problems, and when stored at a cargo space position, it is possible to form a cargo space having a sufficient size in the height direction and the front and back direction, and the side It is an object of the present invention to provide a vehicle seat which allows easy access to a luggage compartment through a door.

  In order to achieve the above object, the present invention is provided with a seat cushion and a seat back, and can be moved between a seating position where an occupant can sit and a loading space where a loading space can be formed in the vehicle body A first hinge portion which allows the seatback to fall forward of the vehicle body, and a foldable body formed by overlapping the seatback which is fallen forward of the vehicle body on the seat cushion, And a second hinge portion movable to the loading space position, wherein, at the loading space position, at least a part of the foldable body is located rearward of the rear end of the seat cushion in the seating position. And the surface direction of the overlapping surface of the folded body is along the side surface in the vehicle body.

  In the vehicle seat according to the present invention, when moving from the seating position to the loading space position, as described above, it is possible to form the folding body by overlapping the seat back on the seat cushion by the first hinge portion. Then, the vehicle seat can be stored at the loading space position by moving the folding body by the second hinge portion. In this luggage compartment position, at least a part of the folding body is located rearward of the rear end of the seat cushion in the seating position, and the plane direction of the overlapping surface of the folding body is along the side surface in the vehicle body. That is, when the vehicle seat is stored in the loading space position, at least a portion of the folding body is located rearward of the side door on the side of the seat cushion in the sitting position, and the plane of the overlapping surface of the folding body The direction is flipped up along the side in the car body.

  By storing the vehicle seat at the loading space position in this manner, the loading space formed in the vehicle body is sufficient because the space occupied by the vehicle seat is not formed in the height direction and the front-back direction. The area can be secured. In addition, since the vehicle seat stored at the loading space position can be prevented from blocking the side door, the loading door can be easily accessed by opening and closing the side door.

  In the vehicle seat described above, it is preferable that the vehicle seat be stored above the rear wheel house at the loading space position. In this case, since the vehicle seat can be stored above the rear wheel house which is likely to be a dead space in the vehicle body, it is possible to effectively utilize the space in the vehicle body to form a luggage compartment of a sufficient size. Become.

  In the vehicle seat described above, it is preferable that the vehicle seat further includes a support bar that is interposed between the foldable body at the luggage compartment position and a floor surface in the vehicle body to support the foldable body. In this case, with the simple configuration, it is possible to stably maintain the vehicle seat stored in the luggage compartment position.

  Hereinafter, preferred embodiments of the vehicle seat according to the present invention will be described in detail with reference to the attached drawings.

  As shown in FIGS. 1 to 3, the vehicle seat 10 according to the present embodiment is used, for example, as a rear row seat of a hatchback type vehicle 12 having two rows of front and rear rows, and a seating position where an occupant can sit It is possible to move between (see FIG. 1) and a loading space position (see FIG. 3) which can form a loading space in the vehicle body. In the following, front, rear, upper and lower, and left and right directions will be described with reference to the direction viewed from the occupant seated on the vehicle seat 10.

  The vehicle seat 10 is composed of a pair of left and right having substantially similar components. When these are distinguished from each other, one of the right side is also referred to as the right rear sheet 10a, and the other of the left side is also referred to as the left rear sheet 10b. The right rear seat 10a and the left rear seat 10b are also collectively referred to as a vehicle seat 10.

  As shown in FIG. 1, when the right rear seat 10a is in the sitting position, the right side door 14 is located on the right side thereof and the left rear seat 10b is located on the left side. When the left rear seat 10b is in the sitting position, the left side door 16 is located on the left side and the right rear seat 10a is located on the right side.

  When changing the right rear seat 10a from the sitting position to the loading space position, as shown in FIG. 2, the right rear seat 10a is folded. By jumping up the right rear seat 10a in the folded state to the side 18 on the right side in the vehicle body, specifically above the rear wheel house 19, the right rear seat 10a is positioned at the loading space as shown in FIG. Moving.

  Next, the configuration for performing this movement will be described in detail. In addition, although the front and rear, right and left, upper and lower in each component of the right rear seat 10a changes with the movement of the right rear seat 10a between the sitting position and the luggage compartment position, hereinafter, unless otherwise specified Description will be made with reference to the direction when in the sitting position.

  FIGS. 4 and 5 are a schematic overall front view and a schematic overall perspective view of the right rear seat 10a in the sitting position, respectively. The right rear seat 10 a mainly includes a seat cushion 20, a seat back 22, a first hinge portion 24, a second hinge portion 26, and a support bar 28.

  In the seat cushion 20, for example, a shock absorbing material (not shown) and a first skin material 32 covering the shock absorbing material are attached to a first base material 30 made of synthetic resin or the like, whereby the occupant is seated. Construct a possible seating surface. On the other hand, in the seat back 22, a shock absorbing material (not shown) and a second skin material 36 covering the shock absorbing material are attached to a second base material 34 made of, for example, a synthetic resin or the like. A backrest surface of an occupant seated on the cushion 20 is configured. At the upper end of the seat back 22, a headrest 38 for supporting the head of the occupant is provided. In order to facilitate understanding of the configuration and the like of the first hinge portion 24 and the second hinge portion 26, in FIG. 5, illustration of the buffer material, the first surface material 32, the second surface material 36 and the like is omitted. There is.

  The first hinge portion 24 is a connecting means for enabling the seat back 22 to rotate (tilt) with respect to the seat cushion 20. Specifically, the first hinge portion 24 includes a first axis support portion 40 attached to the first base member 30, a second axis support portion 42 attached to the second base member 34, and a first axis support portion 40. And a first pivot shaft portion 44 rotatably connecting the second shaft support portion 42.

  The first shaft support portion 40 includes a first outer shaft support member 46 attached to the right rear end portion of the upper surface of the first base member 30 and a first rear end portion attached to the upper surface of the first base member 30. It consists of an inner shaft support member 48. Reinforcing pillars 50 extending in the left-right direction between each other are attached to the first outer shaft support member 46 and the first inner shaft support member 48.

  The first outer shaft support member 46 includes a mounting portion 52, a shaft support portion 56 that rises up so as to be slightly inclined rearward from the mounting portion 52, and a curve slightly rightward from the shaft support portion 56. And the rotation base 58 integrally. The mounting portion 52 in the housing faces the upper right end and the rear end of the first base member 30 and is fixed by, for example, bolting or the like in a state where it is stacked on the upper surface.

  In the attachment portion 52, the lower end position and the upper end position are different. For this reason, the step part 59 opened toward the side which faces the side surface 18 in a vehicle body is formed in the lower part and the upper part. The support bar 28 is accommodated in the step 59. That is, the stepped portion 59 forms an accommodation space for accommodating the support bar 28 between the upper surface of the first base member 30 and the shaft support portion 56. The housing space extends, for example, in the front-rear direction, and its rear end is inclined so as to be separated from the side surface 18 with respect to the front end.

  The support bar 28 is in the shape of a rod that can be accommodated in the accommodation space, and the rear end side thereof is mounted in the step 59. Further, the support bar 28 is pivotable along the surface direction of the upper surface of the first base material 30 about the rear end side mounted in the step portion 59. The support bar 28 is accommodated in the accommodation space when the seat cushion 20 is in the sitting position. On the other hand, when the right rear seat 10a is moved to the loading space position, the support bar 28 is pivoted by its own weight and protrudes from the storage space and extends along the vertical direction (see FIGS. 8 and 9). .

  The shaft support portion 56 rises from the upper portion of the mounting portion 52, and as described above, is slightly inclined rearward. The first shaft member 80 constituting the first pivot shaft portion 44 is supported by the shaft support portion 56.

  The pivot base 58 extends toward the side shaft support member 60 and constitutes a second hinge portion 26 together with the side shaft support member 60. This point will be described later.

  The first inner shaft support member 48 extends along the upper surface of the first base member 30, and in the state of being stacked on the upper surface, the attachment portion 62 fixed by, for example, bolting, and the attachment portion 62 And a shaft support 64 which rises from the The shaft support portion 64 supports a second shaft member 82 that constitutes the first rotation shaft portion 44 together with the first shaft member 80. The second shaft member 82 is slightly shorter than the first shaft member 80.

  On the other hand, the second shaft support portion 42 is a first outer shaft support member 70 attached to the lower right end portion of the front surface of the second base material 34 and a second lower end portion attached to the front surface of the second base material 34 And an inner shaft support member 72. Reinforcing pillars 74 extending in the left-right direction between each other are attached to the first outer shaft support member 70 and the second inner shaft support member 72.

  The first outer shaft support member 70 and the second inner shaft support member 72 are configured substantially similarly to each other, extend along the front surface of the second base material 34, and are stacked on the front surface, for example, bolts It has the attaching parts 76a and 76b fixed by a stopper etc., and the axial penetration parts 78a and 78b which stand up from this attaching parts 76a and 76b, respectively. Insertion holes are formed in each of the shaft insertion portions 78a and 78b.

  The first pivot shaft portion 44 is composed of the first shaft member 80 and the second shaft member 82 as described above. The first shaft member 80 is supported by the shaft support portion 56 of the first outer shaft support member 46, and passes through the insertion hole formed in the shaft insertion portion 78 a of the first outer shaft support member 70. Further, the second shaft member 82 is supported by the shaft support portion 64 of the first inner shaft support member 48, and is passed through the insertion hole formed in the shaft insertion portion 78b of the second inner shaft support member 72. . Thus, the first hinge portion 24 is configured, and the seat back 22 is rotatably coupled to the seat cushion 20 via the first hinge portion 24.

  That is, by adjusting the rotation angle of the second shaft support portion 42 with respect to the first shaft support portion 40 via the first hinge portion 24, the angle of the backrest surface of the seatback 22 with respect to the seat surface of the seat cushion 20 is adjusted. can do. That is, the right back seat 10a is in a state where the occupant seated on the seat cushion 20 can use the seat back 22 as a backrest by the first hinge portion 24 (see FIGS. 1, 4 and 5); By falling to the front of the vehicle body and being superimposed on the seat cushion 20, it is possible to switch between the state where the foldable body 90 is formed (see FIG. 2).

  The second hinge portion 26 allows the folding body 90 to be pivotable about the third shaft member 92 constituting the second shaft support portion 42. The third shaft member 92 extends in the longitudinal direction along the side surface 18 in the vehicle body above the rear end side of the seat cushion 20, and the rear end thereof extends from the side surface 18 in the vehicle body relative to the front end. Inclined to be spaced apart and down.

  The second hinge portion 26 is configured of a first outer side shaft support member 46, a side surface side shaft support member 60, and a third shaft member 92. That is, the first outer shaft support member 46 doubles as a component of the first hinge portion 24 and a component of the second hinge portion 26.

  Specifically, the side shaft support member 60 is, for example, attached to the upper portion of the rear wheel house 19 by, for example, bolting or the like in the side surface 18 (see FIG. 2) in the vehicle body. And a pair of shaft support portions 104 which rise from the mounting portion 102. Further, a pair of annular portions 106 are formed to project from the pivot base 58 of the first outer shaft support member 46. The pair of annular portions 106 intervenes between the pair of shaft support portions 104.

  Through holes are formed in the shaft support portion 104 and the annular portion 106. The third shaft member 92 passes through all the through holes. Thus, the third shaft member 92 is supported by the shaft support portion 104, and the foldable body 90 can be rotated via the second hinge portion 26.

  Therefore, the rotation direction of the first outer shaft support member 46 with respect to the side shaft support member 60 is adjusted by the second hinge portion 26, and the plane direction of the overlapping surface of the foldable body 90 is the floor surface 108 in the vehicle body. When the seat cushion 20 is placed along the seat cushion 20, the seat cushion 20 is in the seating position (see FIGS. 1, 4 and 5). Further, when the plane direction of the overlapping surface of the folding body 90 is made to follow the side surface 18 in the vehicle body by adjusting the above-mentioned turning angle by the second hinge portion 26, the folding body 90 is at the loading chamber position It becomes a state (refer FIG. 3, FIG. 8 and FIG. 9).

  Since the third shaft member 92 of the second hinge portion 26 is disposed inclined as described above, at least a part of the back surface of the seat back 22 is a car by moving the folding body 90 to the loading chamber position. In the side surface 18 of the body, the upper part of the rear wheel house 19 is to be faced. That is, in the vehicle seat 10 stored at the luggage compartment position, at least a part of the folding body 90 is further to the vehicle body rear than the right side door 14 than the rear end of the seat cushion 20 in the sitting position. To position.

  In addition, in order to facilitate movement of the folding body 90 by the second hinge portion 26, for example, a strap (not shown) for gripping may be attached to the front lower end portion or the like of the seat cushion 20. Further, as described above, the right rear end of the seat cushion 20 and the right lower end of the seat back 22 are prevented so that the rotation of the seat cushion 20 and the seat back 22 by the first hinge portion 24 and the second hinge portion 26 is not impeded. Preferably, each of the parts is provided with a notch for avoiding contact with the shaft support 56 and the like.

  The right rear seat 10a according to the present embodiment is basically configured as described above. Further, in the left rear seat 10b, the components disposed on the right end side and the left end side of the right rear seat 10a are disposed on the left end side and the right end side, respectively. The right rear seat 10a and the left rear seat 10b are configured similarly to each other except this point. Therefore, detailed description of the components of the left rear seat 10b will be omitted.

  Hereinafter, an operation of moving the vehicle seat 10 according to the present embodiment between the seating position and the luggage compartment position will be described.

  First, when the right rear seat 10a is in the sitting position, the surface direction of the seat surface of the seat cushion 20 is adjusted along the floor surface 108 in the vehicle body by the second hinge portion 26. Further, the first hinge portion 24 adjusts the angle of the backrest surface of the seatback 22 with respect to the seat surface so that the occupant seated on the seat surface can be used as a backrest. As a result, as shown in FIG. 1, FIG. 4 and FIG. 5, the right rear seat 10a becomes the sitting position, and the occupant can be seated on the right rear seat 10a.

  At this time, the housing space formed by the step portion 59 extends in the front-rear direction as shown in FIG. 5 and is opened toward the right side of the support bar 28. Therefore, the support bar 28 is housed in the housing space.

  In order to move the right rear seat 10a located at the above-mentioned seating position to the loading space position, first, the seatback 22 is turned forward by the first hinge portion 24. That is, it is pivoted forward. As a result, the seat back 22 is superimposed on the seat cushion 20 to form a folded body 90 as shown in FIG. 2, FIG. 6 and FIG.

  Next, the folding body 90 is pivoted about the third shaft member 92 by the second hinge portion 26. With this rotation, as shown in FIGS. 8 and 9, the folding body 90 moves to the loading space position, and at least a part of the back surface of the seatback 22 is above the rear wheel house 19 in the side surface 18 in the vehicle body. Come to

  In this manner, as the right rear seat 10a is stored at the loading space position, as shown in FIGS. 8 and 9, the storage space formed by the step 59 is opened downward in the vertical direction. By this, the support bar 28 accommodated in the accommodation space is pivoted by its own weight and protrudes from the accommodation space. As a result, the support bar 28 intervenes between the lower end of the foldable body 90 and the floor surface 108 in the vehicle body. That is, the folding bar 90 can be supported from below by the support bar 28. Therefore, it is possible to stably maintain the state in which the right rear seat 10a is stored at the loading space position.

  Similarly, the left rear seat 10b can be moved from the seating position and stored at the luggage compartment position. By storing the right rear seat 10a and the left rear seat 10b at the loading space position in this manner, a large loading space is formed at the rear of the front row seat 110 of the vehicle 12 in which the trunk room and the rear riding room are connected. Ru. Of course, it is also possible to move the vehicle seat 10 stored at the loading space position to the sitting position by passing the above steps in reverse.

  From the above, when the vehicle seat 10 is in the luggage compartment position, the plane direction of the overlapping surface of the foldable body 90 is in the vehicle body above the rear wheel house 19 behind the right side door 14 or the left side door 16. It is stored while being flipped up along the side surface 18. As a result, a space occupied by the vehicle seat 10 is not formed in the height direction and the front-rear direction of the luggage compartment formed in the vehicle body, and a sufficient size can be ensured. In addition, since the vehicle seat 10 can be stored utilizing the upper part of the rear wheel house 19 which is likely to be a dead space, a space inside the vehicle body can be effectively used to form a luggage compartment of a sufficient size. .

  As described above, the vehicle seat 10 stored at the luggage compartment position blocks the right side door 14 and the left side door 16 even when the luggage compartment having a sufficient size in the height direction and the front-rear direction is formed. Can be suppressed. Therefore, the cargo compartment can be easily accessed by opening and closing the right side door 14 and the left side door 16.

  Further, the support bar 28 may be protruded from the lower end of the foldable body 90 by its own weight only when the vehicle seat 10 is in the loading space position, and may be interposed between the foldable body 90 and the floor surface 108 in the vehicle body. it can. Therefore, for example, it is possible to stably maintain the state in which the right rear seat 10a is stored at the loading space position without requiring a step of manually arranging the support bar 28 or the like. Also, the space for providing the support bar 28 does not increase.

  Although the present invention has been described above by way of preferred embodiments, the present invention is not limited to the above embodiments, and it goes without saying that various modifications can be made without departing from the scope of the present invention. Yes.

  Although the vehicle seat 10 according to the above embodiment is used as the rear row seat of the hatchback type vehicle 12 having the front and rear two rows of seats, it is not particularly limited thereto. For example, it is also possible to use the vehicle seat 10 as a seat or the like in the last row of a vehicle having three or more rows of seats.

  In addition, although the vehicle seat 10 according to the above-described embodiment is stored above the rear wheel house 19 when the vehicle seat 10 is at the luggage compartment position, it is not particularly limited thereto. When the vehicle seat 10 is in the loading position, at least a portion of the folding body 90 is rearward of the rear end of the seat cushion 20 in the sitting position, in other words, from the right side door 14 or the left side door 16 Also, it should be located in the rear. Even in this case, since the vehicle seat 10 stored at the luggage compartment position does not block the right side door 14 or the left side door 16, the vehicle seat 10 can not be closed via the right side door 14 or the left side door 16. You can access the luggage compartment.

  Furthermore, although the vehicle seat 10 according to the above-described embodiment includes the support bar 28 that can protrude from the lower end of the foldable body 90 by its own weight as described above, the present invention is not particularly limited thereto. The support bar 28 may be configured to be able to support the folded body 90 from below while being interposed between the lower end of the folded body 90 and the floor surface 108 in the vehicle body. The vehicle seat 10 may not have the support bar 28.
