  However, since the ottoman has a certain size, it can be considered that the ottoman can be effectively used by adding other functions besides the use of the ottoman.

  In the above-mentioned Patent Document 1, a ottoman is used as a center table by moving the ottoman to the side of the seat, so that the ottoman also has a function as a table and effectively uses the ottoman.

JP 2003-205778 A

  By the way, when the seat device is mounted in the vehicle interior, it is necessary to install the seat device in a limited space in the vehicle interior.

  In addition, the seat device needs to be firmly fixed to the floor surface in order to securely hold the occupant's body on the seat against acceleration and deceleration in all directions caused by traveling of the vehicle.

  In this regard, in Patent Document 1 described above, a rotation center (axis) is provided on the lower surface of the seat cushion, and an L-shaped support arm that can rotate about 90 degrees around the rotation center is used. There is a problem that the ottoman is only locked to the side tip and the ottoman has a center table function, and these requirements cannot be sufficiently satisfied.

  That is, in Patent Document 1, when switching between the ottoman and the center table, the L-shaped support arm is rotationally moved between the front and side of the seat, but the shape of the seat cushion is a square, In order to avoid the corner portion of the seat cushion, it is necessary to lengthen the arm length, and accordingly, the movement trajectory of the support arm becomes large, and the seat device cannot be arranged compactly.

  Further, in Patent Document 1, the L-shaped support arm is rotatable about 90 degrees with the rotation center of the lower surface of the seat cushion including one corner of the seat within the movable range thereof. Thus, it cannot be fixed at the four corners of the lower surface of the seat cushion, and the seat device cannot be firmly fixed to the floor surface.

  In view of this, the present invention provides a seat device for a vehicle in which a seat device provided with the ottoman can be arranged in a compact manner while effectively utilizing the ottoman by adding a function other than the ottoman function to the ottoman. Further, it is an object of the present invention to provide a vehicle seat device that can be firmly fixed to a floor surface by fixing the four corners of the lower surface of the seat cushion as in the conventional seat device.

  A vehicle seat device according to the present invention is a vehicle seat device in which a plate-like ottoman on which a foot is placed is installed on the vehicle front side of a seat cushion of a seat in a vehicle interior, and one end portion in the vehicle width direction of the ottoman is A rotation mechanism portion that supports the seat or the floor is provided near the corner portion of the seat around the one end portion, and the rotation mechanism portion is arranged in the vehicle width direction on the vehicle front side of the seat cushion. From the basic form that extends, the ottoman rotates in the vehicle width direction about the rotation axis extending in the vehicle front-rear direction, and is in an approximately inverted state in which the other end in the vehicle width direction is directed upward. From the first form and the first form, the ottoman turns to the rear of the vehicle around a turning shaft extending in the vehicle width direction, and the flat surface of the ottoman becomes a substantially horizontal state on the side of the seat cushion. Configured to form Than it is.

  According to the above-described configuration, the rotation mechanism portion that supports the one end portion in the vehicle width direction of the ottoman in the vicinity of the corner portion of the seat with respect to the seat or the floor is provided. A basic configuration extending in the vehicle width direction on the front side of the vehicle, and a substantially inverted state in which the other end portion in the vehicle width direction is directed upwards by rotating in the vehicle width direction around a rotation shaft extending in the vehicle front-rear direction. And a second form in which the flat surface of the ottoman is in a substantially horizontal state on the side of the seat cushion by turning rearward about the turning shaft extending in the vehicle width direction. .

  In other words, the rotating mechanism provided near the corner of the seat changes the ottoman form to the basic form, the first form, and the second form. It is not necessary to form a rotating shaft or the like. Therefore, the mounting rigidity of the seat to the floor surface can be improved.

  Also, when changing the ottoman's form, the ottoman's movement is changed in order to change the ottoman's form via the first form in which the other end in the vehicle width direction of the ottoman is in an approximately inverted state directed upward. The locus can be made compact in plan view.

  In addition, the specific form of the rotation mechanism is not particularly limited as long as it can change the form of the ottoman, such as those having a plurality of rotation shafts and ball joints.

  Also, the structure for supporting the ottoman may be a simple rod member or a flat plate member. Moreover, the member formed by bending the rod member into an L shape, a U shape, or a B shape may be used.

  In one embodiment of the present invention, the rotation mechanism section includes a substantially L-shaped link member comprising a vertical link section extending in the vehicle vertical direction and a horizontal link section extending in the vehicle width direction in the basic form, The lower end of the vertical link portion of the link member is constituted by a rotation support portion that rotatably supports the seat or the floor, and the ottoman is supported by the horizontal link portion of the link member, and the horizontal link The part is configured to be rotatable about the rotation center.

  According to the said structure, the rotation mechanism part is a substantially L-shaped link member which consists of a vertical link part and a horizontal link part, and the rotation support part which supports the lower end of a vertical link part with respect to a sheet | seat or a floor. And the ottoman is supported by the lateral link portion of the link member, and is rotatable about the lateral link portion.

  For this reason, the rotation mechanism portion can be configured with a simple mechanism such as a substantially L-shaped link member and a rotation support portion, and this rotation support portion is set at the lower end of the vertical link portion of the link member. Therefore, a large pivot support portion is disposed below the seat cushion, and the entire upper surface of the seat cushion can be effectively used as a seating surface.

  Therefore, while being able to comprise a rotation mechanism part compactly, the deterioration of the seating comfort of a seat cushion can also be prevented.

  In one embodiment of the present invention, when the rotation mechanism portion is shifted from the basic configuration to the first configuration, the lateral link portion of the substantially L-shaped link member is centered on the rotation support portion. By turning in the vehicle width direction, the lateral link portion is configured to be oriented in a substantially vertical direction, and when shifting from the first mode to the second mode, the vehicle width direction can be changed by changing the mode. The vertical link portion extending in the vehicle is pivoted forward of the vehicle around a pivot support portion having a pivot shaft extending in the vertical direction, so that the vertical link portion extends in the vehicle longitudinal direction. From the form and the first intermediate form, by the form change, the lateral link part extending in the up-down direction is rotated rearward of the vehicle around a turning fulcrum part having a turning shaft extending in the vehicle width direction. Thus, the lateral link portion is oriented toward the rear of the vehicle. Those configured so as to form a second intermediate form.

  According to the above configuration, when shifting from the basic form to the first form, the lateral link part of the substantially L-shaped link member is pivoted in the vehicle width direction around the pivot support part, thereby causing a substantially vertical direction. When the transition from the first form to the second form takes place, the longitudinal link portion of the substantially L-shaped link member is turned substantially parallel to the vehicle front-rear direction by turning forward in the vehicle. One intermediate form and the 2nd intermediate form used as the form which orient | assigns the vehicle back by turning the horizontal link part of a substantially L-shaped link member to the vehicle back are made | formed.

  For this reason, even if it comprises a rotation mechanism part by the substantially L-shaped link member which consists of a vertical link part and a horizontal link part, basic form-> 1st form-> 1st intermediate form-> 2nd intermediate form-> 2nd In the process of changing the form and the form of the ottoman, the relatively long lateral link part is changed in a state in which it is oriented substantially in the vertical direction, so the form of the ottoman is maintained in a state of maintaining a compact form in plan view. Can be changed.

  Therefore, the ottoman can be changed in a compact space, and the seat device can be arranged in a compact manner while improving convenience by adding other functions to the ottoman.

  In one embodiment of the present invention, the flat surface of the ottoman is formed with one surface as a cushion surface and the other surface as a storage surface, and in the case of the second embodiment, a side surface of the substantially L-shaped link member is formed. The link portion supports the flat surfaces of the ottoman so that they can be directed upward.

  According to the above configuration, the flat surface of the ottoman is formed with one surface as a cushion surface and the other surface as a storage surface, and both flat surfaces of the ottoman are directed upward by the lateral link portion in the second configuration. I will support it as I can.

  For this reason, when using the ottoman on the side of the seat cushion, it can be used by appropriately selecting it as an auxiliary seat (expansion of the seating surface) or a center table.

  Therefore, the function of the ottoman can be further increased, and one ottoman can be used more effectively.

  According to this invention, in order to change the form of the ottoman, the form of the ottoman is changed from the basic form, the first form, and the second form in the rotation mechanism provided near the corner of the seat. It is not necessary to form a rotation center or the like under the seat cushion.

  Also, when changing the ottoman's form, the ottoman's movement is changed in order to change the ottoman's form via the first form in which the other end in the vehicle width direction of the ottoman is in an approximately inverted state directed upward. The locus can be made compact in plan view.

  Therefore, by adding other functions to the ottoman in the vehicle seat device, the seat device equipped with the ottoman can be arranged in a compact manner while effectively utilizing the ottoman, and further rotated to the lower part of the seat cushion. Since the center is not formed, the seat device can be firmly fixed to the floor surface by fixing the four corners of the lower surface of the seat cushion as in the conventional general seat device.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, the overall structure of the vehicle seat device of the present embodiment will be described with reference to FIGS. FIG. 1 is a transparent perspective view of the sheet device, and FIG. 2 is a transparent plan view of the sheet device.

Among these, a locking piece 27 that engages with the above-described stopper iron pieces 28 and 29 is provided at the center of the lateral link portion 22 a that is inserted into the ottoman main body 21 and supports the ottoman main body 21.

  In addition, this L-shaped link member does not need to be a right-angled L-shape completely, and if it is a link member comprised by two link parts, it will not specifically limit.

  The L-shaped link member 22 is supported by the support bracket 24 via the rotation support portion 23 at the lower end of the vertical link portion 22b. Further, the ottoman main body 21 is supported by the lateral link portion 22a through the rotation angle change holding mechanism 25 and the sleeve portions 26 and 26.

Thus, by supporting the ottoman main body 21 with the L-shaped link member 22, the rotation support portion 23 is disposed below the seat cushion 11, so that the entire upper surface of the seat cushion 11 is effective as a seating surface. Can be used.
Therefore, it is possible to prevent the sitting comfort of the seat cushion 11 from being deteriorated.

  In this embodiment, the vertical link portion 22b of the L-shaped link member 22 is disposed at the front left end of the seat cushion 11, but the same is true if it is disposed near the front corner of the seat cushion 11. Since the function can be achieved, the vertical link portion 22b of the L-shaped link member 22 may be disposed at the front right end of the seat cushion 11.

  Further, if securing the seating surface of the seat cushion 11 is not taken into consideration, a rotation support portion or the like may be provided directly on the upper surface of the seat cushion 11 and the ottoman main body 21 may be supported by a rod-shaped link member. .

  The rotation support portion 23 has an L-shaped link member 22 and an ottoman main body 21 by two axes of a first rotation axis P extending in the vehicle front-rear direction and a second rotation axis Q extending in the vertical direction in the state of FIG. Is configured to rotate.

  Specifically, a flange portion 22c formed at the lower portion of the L-shaped link member 22 is pivotally attached to the rotation base body 23a by a pivot bolt 23b extending in the vehicle front-rear direction (first rotation axis P). A rotary base 23a is pivotally attached to a support bracket 24 (not shown in FIG. 3) with a pivot bolt (not shown) extending in the vertical direction (second rotation axis Q), so that a general radio or the like is used. It forms two orthogonal axes like a simple antenna.

  As described above, by providing the rotation support portion 23 with the rotation shaft, the ottoman main body 21 can be changed into various forms as described later.

  In addition, in addition to these two shafts, when a third rotation shaft extending in the vehicle width direction or the like is provided, it is possible to further increase variations in the form of the ottoman body 21. But in this embodiment, since the structure of the rotation support part 23 becomes complicated, the 3rd rotation axis is not employ | adopted.

  Moreover, you may comprise this rotation support part 23 with a ball joint. In this case as well, various forms of the ottoman main body 21 can be changed.

Next, changes in the configuration of the ottoman mechanism 2 configured as described above will be described with reference to each of the configuration diagrams of FIGS. 6 to 12 and the sectional views of FIGS. In addition, about the same component, a code | symbol is attached | subjected and description is abbreviate | omitted.
First, the change from the ottoman basic form to the auxiliary seat form will be described with reference to FIGS.

  As shown in FIG. 6, first, from the basic form of the ottoman using the ottoman main body 21 of FIG. 1 as the ottoman, the lower end of the ottoman main body 21 is rotated and the lateral link portion 22a of the L-shaped link member 22 is rotated. As a center, it is folded to the seat cushion 11 side and changed to the ottoman storage form. At this time, since the rotation angle of the ottoman main body 21 is only held by the rotation angle change holding mechanism 25, the ottoman main body 21 can be easily changed to the ottoman storage form by pushing the lower part of the front end of the ottoman main body 21 toward the vehicle rear side. To do.

  As shown in FIG. 7, the right end portion (left side in the drawing) of the ottoman main body 21 is 90 degrees to the vehicle upper side around the first rotation axis P extending in the vehicle front-rear direction from the storage configuration of FIG. 6. By rotating, the ottoman main body 21 is changed to an upward pointing form in which the right end portion is directed upward. In this state, the ottoman main body 21 is in an approximately inverted state in which a short side in the vertical direction extends in the vehicle width direction.

  As shown in FIG. 8, after that, the ottoman body 21 is turned 90 degrees forward of the vehicle around the second turning axis Q extending in the vertical direction from the form of FIG. It changes to the front-back direction form extended in the front-back direction. Even in this state, the substantially inverted state in which the short side of the ottoman main body 21 extends in the vehicle front-rear direction is maintained.

  As shown in FIG. 9, the first rotation axis P extending in the vehicle width direction from the configuration of FIG. 8 (the rotation support portion 23 is rotated 90 degrees in FIG. The ottoman body 21 is rotated 90 degrees toward the rear side of the vehicle, and the ottoman body 21 is laterally retracted to the side of the seat cushion 11 (folded to the side of the seat cushion 11). Change.

  As shown in FIG. 10, finally, from the configuration of FIG. 9, the ottoman main body 21 is once pulled up to the vehicle upper side, and the upper end of the ottoman main body 21 is centered on the lateral link portion 22 a of the L-shaped link member 22. By rotating the seat cushion 11 outward (in the vehicle width direction), the ottoman main body 21 can be changed to an auxiliary seat configuration that extends in the vehicle width direction at a height substantially matching the upper surface of the seat cushion 11. .

By such a series of changes in the form, the ottoman body 21 can be used as an auxiliary seat on the side of the seat cushion 11 (or in a state in which the cushion surface of the seat cushion 11 is enlarged).
In addition, the BB arrow sectional drawing of FIG. 9 is shown in FIG. 13, and the CC sectional view taken on the line of FIG. 10 is shown in FIG.

  As shown in FIG. 13, when the ottoman main body 21 is changed to the retracted form on the side of the seat cushion 11, the ottoman main body 21 has a cushion surface 21 </ b> A that faces upward in the ottoman basic form on the side of the seat cushion 11. Orientation, the table surface 21B faces outward.

  For this reason, when the ottoman body 21 is deployed on the side of the seat cushion 11, in order to turn the cushion surface 21A upward, as described with reference to FIG. 11 is required to rotate outward (clockwise in FIG. 13).

  In this way, by pulling up and rotating the ottoman main body 21, the stopper iron piece 29 provided inside the ottoman main body 21 is secured to the locking piece 27 of the lateral link portion 22a of the L-shaped link portion as shown in FIG. And further rotation (clockwise rotation in FIG. 14) is restricted, and the substantially horizontal state is maintained.

  In consideration of the use of the ottoman main body 21 as an auxiliary seat, when the cantilever support using only the L-shaped link member 22 is considered to have low support rigidity, the front side of the side portion of the adjacent seat device 101 is used. Alternatively, the support 102 of the ottoman main body 21 may be formed to support the outer end of the ottoman main body 21 so as to support both ends.

  On the other hand, the change to the center table form further requires the form change of FIG. 11 and FIG. 12 from the form of FIG. Therefore, the change to the center table form will be described with reference to FIGS.

  As shown in FIG. 11, the ottoman main body 21 is slid and moved from the lateral link portion 22 a of the L-shaped link member 22 once to the vehicle rear side from the form of FIG. 9. If the ottoman main body 21 is rotated 90 degrees in the vehicle width direction around the L-shaped link member 21 (counterclockwise rotation in FIG. 13), the locking piece 27 of the lateral link portion 22a This is because the stopper iron piece 28 interferes from the side and cannot be engaged.

  As shown in FIG. 12, the stopper iron piece 28 can be rotated while avoiding the position of the locking piece 27 by rotating the ottoman body 21 90 degrees around the lateral link portion 22a in the vehicle width direction from the form of FIG. it can. Therefore, after that, the stopper iron piece 28 can be engaged with the locking piece 27 of the lateral link portion 22a from above by sliding the ottoman main body 21 forward of the vehicle.

  FIG. 15 is a cross-sectional view of the state in which the stopper iron piece 28 is engaged with the locking piece 27 of the lateral link portion 22a.

  By holding the ottoman main body 21 in this way, the table surface 21B is directed upward, and the ottoman main body 21 can take the center table form.

  Although not shown, in this case as well, a support base for the ottoman main body 21 is formed on the side portion of the adjacent sheet apparatus 1 and the outer end of the ottoman main body 21 is supported, so that it is configured as a both-end support. May be.

  As described above, in this embodiment, the ottoman body 21 can be changed from a basic ottoman form to an auxiliary seat form or a center table form by changing the form of the ottoman body 21 into a plurality of forms. For this reason, it becomes possible to add another several function to the ottoman main body 21, and the ottoman main body 21 can be utilized effectively.

  Further, in this embodiment, since the L-shaped link member 22 and the rotation support portion 23 for such a shape change are provided in the vicinity of the corner portion of the seat cushion 11, a rotation shaft or the like is provided at the center lower portion of the seat cushion 11. The seat device 1 may not be provided, and can be firmly fixed to the passenger compartment floor F by the fixing brackets 18 at the four corners below the seat cushion 11.

  Further, as in the case where a rotating shaft or the like is provided at the center lower portion of the seat cushion 11, it is not necessary to consider the length from the center of the seat cushion 11 to the corner portion, so the seat device 1 is compactly arranged in the vehicle interior can do.

  In addition, in this embodiment, when changing the form of the ottoman main body 21, the ottoman main body 21 is changed to the substantially inverted state so that the short side of the ottoman main body 21 extends in the vehicle width direction or the vehicle front-rear direction. The movement locus of the ottoman main body 21 can be made a compact space in a plan view.

Next, an example of a form change of the ottoman body 21 in another embodiment will be described with reference to FIG.
In this embodiment, the rotation support part 123 is further provided with a third rotation shaft to increase the form change of the ottoman main body 21. Other constituent elements are denoted by the same reference numerals and description thereof is omitted.
