  However, since the above-described conventional technology requires a plurality of links, the number of parts is large, and an operation space for rotating each link is widely required. The present invention has been created as a solution to the above-described problems, and the problem to be solved by the present invention is to rationally configure a configuration for storing and deploying an ottoman with a small number of parts.

In order to solve the above problems, the vehicle seat of the present invention takes the following means.
A first invention is a vehicle seat in which an ottoman serving as a footrest is disposed at a front portion of a seat cushion so that the ottoman can be stored and deployed, and a base cushion that supports the ottoman, and a posture change of the seat cushion or the seat back And a transmission member that transmits the amount of motion movement associated with the movement. The connection between the ottoman and the base is such that a slide pin provided on one of them is slidably fitted in a long hole formed on the other, so that the ottoman is in a predetermined storage position and a predetermined expansion with respect to the base. The connection is supported in such a manner that it can be stored and unfolded in the front-rear direction. The transmission member changes the posture of the seat cushion or the seat back from the normal use position to a predetermined comfort posture position, thereby deploying the ottoman from the predetermined storage position to the predetermined deployment position, and the seat cushion or the seat back is predetermined. By returning from the comfortable posture position to the normal use position, the ottoman is stored from the predetermined deployment position to the predetermined storage position.

  According to the first aspect of the present invention, the ottoman is connected to the base by the connecting structure of the long hole and the slide pin, and the transmission member for transmitting the movement amount accompanying the posture change of the seat back or the seat cushion is set to the ottoman. With such a simple configuration, the seat cushion or the seat back can be deployed and stored in conjunction with the ottoman by changing the posture from the normal use position to the predetermined comfortable posture position and vice versa. Can do. In this way, the configuration for storing and deploying the ottoman can be rationally configured with a small number of parts.

  The second invention is the following structure in the first invention described above. The transmission member is configured as a skeleton member that connects the seat back and the ottoman to form the skeleton of the seat cushion. The seat cushion slides forward and the ottoman moves forward by tilting the backrest angle of the seat back from the position of standing up, which is the normal use position, to the position of tilting backward to the predetermined comfort posture position. It is deployed to a predetermined deployment position.

  According to the second aspect of the invention, the seat cushion can be slid to the front position corresponding to the comfort posture in accordance with the operation of tilting the seat back backward and switching to the comfort posture. Thus, the entire posture of the vehicle seat including the ottoman can be switched between the normal posture and the comfortable posture.

  A third invention has the following configuration in the first or second invention described above. The ottoman is provided in a state where it is hinged to the front part of the transmission member so as to be rotatable up and down. The transmission member supports the base so that the front part of the transmission member moves diagonally forward and upward by receiving the movement of changing the posture of the seat cushion or the seat back from the normal use position to the predetermined comfortable posture position. Has been. By moving the front portion of the transmission member obliquely upward to the front, the ottoman rotates from the state of the hanging position with respect to the base upward to the predetermined deployment position according to the guide shape of the slide pin and the long hole. It is configured to be pushed.

  According to the third aspect of the invention, the transmission member is supported with respect to the base so that the front portion thereof moves forward and obliquely upward by the operation of switching the seat cushion or the seat back to the comfortable posture. By the operation in which the transmission member is pushed forward, the connecting portion between the transmission member and the ottoman is efficiently pushed forward and obliquely upward. Therefore, even if the shape of the long hole is not raised, it is possible to rotate the ottoman upward while efficiently moving the ottoman diagonally forward (in the direction of raising the footrest position) by the movement of the transmission member. Can do.

Each reclining device 6 is returned to the state in which the backrest angle of the seat back 2 is locked again by releasing the operation of the release lever. In addition, since the basic structure of each reclining apparatus 6 is the same as what was disclosed by literature, such as Unexamined-Japanese-Patent No. 2011-116303, the specific description shall be abbreviate | omitted.

  In the seat cushion 3, the side frames 3 </ b> A that are long in the front-rear direction forming the left and right side skeletons are connected to the lateral walls 5 (base plates 5 </ b> B) located on both outer sides in the middle part thereof, At the rear end portions thereof, they are provided as being connected to the side frames 2A of the seat back 2 described above. Specifically, the side frames 3A of the seat cushion 3 are coupled so that their intermediate portions can slide obliquely in the forward upward direction with respect to the lateral walls 5 (base plate 5B). Specifically, as shown in FIG. 3, slide pins 3 </ b> P <b> 2 projecting outward are provided at intermediate portions of the side frames 3 </ b> A of the seat cushion 3, and these slide pins 3 </ b> P <b> 2 are connected to the horizontal walls 5. By being fitted in each of the long holes 5C that are curved in the upward direction formed on the (base plate 5B), the base plate 5B is connected so that it can slide along these hole shapes. .

  As shown in FIGS. 4 to 6, each side frame 3 </ b> A of the seat cushion 3 swings back and forth with respect to the rear end of each side frame 2 </ b> A of the seat back 2. It is axially connected so that it can rotate. Specifically, an extension part 3B extending rearward from the outer shape of the seat cushion 3 is formed at the rear end part of each side frame 3A of the seat cushion 3, and these extension parts 3B are The extension portions 2B formed at the lower ends of the side frames 2A of the seat back 2 and extending downward from the outer shape of the seat back 2 are axially connected to each other by connecting pins 3P1. It becomes the composition.

  As shown in FIG. 4, the seat cushion 3 has slides provided at intermediate portions of the side frames 3 </ b> A in a state where the backrest angle of the seatback 2 is at an angle position close to the normal use position. As the pin 3P2 is located at the rear lower end of the long hole 5C of each lateral wall 5 (base plate 5B), a normal use position closer to the rear that is an appropriate seating position with respect to the backrest angle position of the seat back 2 It is set as the state hold | maintained in this state. However, as shown in FIGS. 5 to 6, the seat cushion 3 is tilted toward the rear side where the backrest angle of the seat back 2 becomes the comfortable posture from the normal use position, so that the connecting pin 3 </ b> P <b> 1. It is pushed and moved through. As a result, the seat cushion 3 is configured such that the front part 3F is pushed forward and obliquely upward while the posture of the slide pin 3P2 is changed along the shape of the long hole 5C and the posture is changed obliquely upward. It has come to be.

  As a result of the above movement, the seat cushion 3 is lowered to the position of the comfort posture shown in FIG. 6 so that the front part 3F moves forward and the thigh of the seated occupant is raised to a high position. It will be in a lifted state so that it can be supported by. As a result, the seat cushion 3 moves the thigh to the front so that the angle of the thigh (hip angle) with respect to the pelvis does not become too wide. It becomes a state supported by a comfortable posture lifted by 3F (a comfortable posture state). The position of the seat cushion 3 is also fixed when the backrest angle of the seat back 2 is fixed by the lock of each reclining device 6 described above.

  As shown in FIG. 3, the ottoman 4 includes a plate-like ottoman main body 4A serving as a footrest, a side frame 4B coupled to both left and right sides of the ottoman main body 4A, and a rear side on the upper end of each side frame 4B. And a slide plate 4D assembled in a state of being slid in the surface direction on the plate surface of the ottoman body 4A. In the ottoman main body 4A, the upper end portions of the side frames 4B coupled to the left and right side portions thereof are axially coupled to the front end portions of the side frames 3A of the seat cushion 3 by the coupling pins 3P3 so as to be rotatable. Is provided. Here, each side frame 3A of the seat cushion 3 corresponds to a “transmission member” of the present invention. The front end portions of the side frames 3A of the seat cushion 3 are rigidly coupled to each other by bridging the front frame 3Fa constituting the skeleton of the front portion 3F of the seat cushion 3 therebetween. It is assumed that it is connected.

  When the vehicle seat 1 is in the normal use position shown in FIG. 4, the ottoman body 4 </ b> A is held in a storage state in which the ottoman body 4 </ b> A is compactly folded so as to overlap the front side portion of the seat cushion 3. The In this state, each arm portion 4C extending from the upper end portion of each side frame 4B of the ottoman 4 to the rear side has a shape extending in a curved shape in the backward upward direction in a concave shape on the upper side. These arm portions 4C have a slight rise in the shape extending to the rear side, and are almost horizontal, so that they do not protrude upward from the outer shape of the seat cushion 3 and are within the shape of the seat cushion 3. It is supposed to be in a compact state. These arm portions 4C are formed with long holes 4C1 having a slightly curved shape that is concave on the upper side, the same as the shape of each arm portion 4C, penetrating in the axial direction (sheet width direction).

  As shown in FIG. 3, each of the arm portions 4C described above is fitted with the slide pins 5P protruding inwardly provided in the base plate 5B of each lateral wall 5 in the long holes 4C1. The rotational posture with respect to each lateral wall 5 (base plate 5B) is determined by the shape of each elongated hole 4C1. That is, as shown in FIG. 4, each of the long holes 4C1 described above does not have an arc shape around the rotation center (connecting pin 3P3) of the ottoman body 4A, and the rotation of each arm portion 4C (ottoman body 4A). The posture is restricted by the shape of each long hole 4C1 with which each slide pin 5P is engaged. Therefore, due to the engagement structure between the long holes 4C1 and the slide pins 5P, the rotational position of the ottoman body 4A in a normal state is in a storage position that is compactly folded so as to overlap the front side portion of the seat cushion 3. It is held as a regulated state. Here, each of the long holes 4C1 corresponds to a “long hole” of the present invention, and each slide pin 5P corresponds to a “slide pin” of the present invention.

  As shown in FIG. 5, the ottoman main body 4A pushes the seat cushion 3 (each side frame 3A) obliquely upward in the forward direction by the operation of the seat back 2 (each side frame 2A) being tilted backward. When it is moved, the upper end of each side frame 4B is pushed and moved diagonally forward and upward in a manner that it is pushed by each side frame 3A of the seat cushion 3 via the connecting pin 3P3. At this time, the ottoman main body 4A slides forward with respect to the slide pins 5P fixed to the respective lateral walls 5 (base plate 5B) by the pushing operation of the long holes 4C1 of the respective arm portions 4C. To move. Thereby, the posture of the ottoman main body 4A (arm portion 4C) is raised to the front side while being guided by the shape of each elongated hole 4C1 in accordance with the operation of being pushed and moved.

  The movement in which the ottoman body 4A is raised to the front side is accompanied by the movement in which the front portion 3F of the seat cushion 3 is lifted upward, so that the shape of each elongated hole 4C1 is almost horizontal at the initial stage. Nevertheless, the movement is guided so as to be efficiently lifted upward. Further, since each long hole 4C1 is not a straight shape but has a curved shape that is slightly concave on the upper side, each slide pin 5P is pressed against the inner peripheral surface of each long hole 4C1 during the movement. The power is reduced, so that the slide movement can be performed smoothly without getting stuck. Therefore, when the seat back 2 is brought down to the position of the comfort posture as shown in FIG. 6, the position of the ottoman body 4A is moved obliquely upward and the angle thereof is changed upward. Thus, the lower crus of the seated occupant can be placed in a deployed position.

  In the state of the unfolded position, the ottoman main body 4A is restricted in its rotational posture by the engagement structure of the long holes 4C1 and the slide pins 5P even if the lower leg of the seated occupant is placed thereon. It is kept in the state that was done. Therefore, the ottoman body 4A is supported by the engagement structure between the long holes 4C1 and the slide pins 5P at a distant position spaced rearward and downward from the center of rotation (the connecting pin 3P3). The load on the lower leg is supported with a strong force. The rotation posture of the ottoman main body 4A is fixed by fixing the backrest angle of the seat back 2 by the lock of each reclining device 6 described above. The ottoman body 4A is moved in the direction opposite to the above by raising the seat back 2 from the rearward tilt position to the normal standing position, and is again folded into the front lower portion of the seat cushion 3. Returned to the stored position (see FIG. 4).

  By the way, as shown in FIG. 6, by raising the ottoman body 4A to the deployed position as described above, the cushion pad 3C disposed on the upper surface thereof is also raised to the front side. The cushion pad 3C is formed by extending a part of the cushion pad 3C set on the seating surface portion of the seat cushion 3 to the front side, and the ottoman body 4A is expanded and lifted as described above. Due to the difference in the height of the center of rotation from the ottoman body 4A due to its thickness, the tip end (lower end) moves relative to the front side of the ottoman body 4A. Therefore, a slide plate 4D that moves following the movement of the cushion pad 3C is attached to the ottoman body 4A so that the portion that protrudes toward the front side of the cushion pad 3C can be supported.

  As shown in FIG. 3, the slide plate 4 </ b> D is attached in a state in which the slide plate 4 </ b> D can slide in the surface direction on the footrest surface (front surface) of the ottoman body 4 </ b> A. Specifically, sliders 4D1 are attached to the left and right positions of the back surface of the slide plate 4D, and the sliders 4D1 are attached to the slide rails 4A1 attached on the leg placing surface of the ottoman body 4A. It is the state assembled | attached so that sliding was possible. As a result, the slide plate 4D is attached to the ottoman body 4A so as to be guided so as to be slidable back and forth. As shown in FIGS. 4 to 6, the slide plate 4D is integrally attached to the back surface of the cushion pad 3C, and the ottoman together with the cushion pad 3C according to the movement in which the ottoman body 4A is deployed and stored. By sliding with respect to the main body 4A, as shown in FIG. 6, the portion of the cushion pad 3C that protrudes from the ottoman main body 4A to the front side can be placed and supported from below.

  A skin material 3D is stretched on the surface portion of the cushion pad 3C described above. This skin material 3D is also formed by extending a part of the skin material 3D stretched on the seating surface of the seat cushion 3 to the front side, and continuously covers the seat cushion 3 to the ottoman 4. It is provided in a state.

  Thus, according to the configuration of the vehicle seat 1 of the present embodiment, the ottoman 4 is connected to the lateral wall 5 (base) by the connecting structure of the long hole 4C1 and the slide pin 5P, and the seatback 2 is connected to the ottoman 4 The seat cushion 3 is normally used with a simple configuration in which a transmission member (in this embodiment, each side frame 3A of the seat cushion 3 serves as a transmission member) for transmitting the movement amount associated with the posture change of the seat is used. By obtaining a configuration in which the ottoman 4 can be deployed and stored in conjunction with each other by changing the posture from the position (the state shown in FIG. 4) to the predetermined comfortable posture position (the state shown in FIG. 6) and vice versa. Can do. In this manner, the configuration for storing and deploying the ottoman 4 can be rationally configured with a small number of parts.

  Further, as described above, the transmission member is constituted by the skeletal member (side frame 3A) that connects the seat back 2 and the ottoman 4 to form the skeleton of the seat cushion 3, so that the backrest angle of the seat back 2 is increased. The seat cushion 3 can be slid forward and the ottoman 4 can be deployed to a predetermined deployment position by tilting the seat cushion from the normal use position to the comfort posture position. Accordingly, the seat cushion 3 can be slid to the front position corresponding to the comfort posture in accordance with the operation of switching the seat back 2 to the comfort posture, and the vehicle including the ottoman 4 with a more rational configuration. The entire posture of the medical seat 1 can be switched between a normal posture and an easy posture.

  Further, the transmission member (each side frame 3A of the seat cushion 3) moves the seat back 2 to the comfortable posture so that the front portion (3F) moves forward obliquely upward with respect to the lateral wall 5 (base). As a result, the connecting portion between the transmission member (each side frame 3A) and the ottoman 4 is efficiently pushed diagonally forward and upward by the action of the transmission member (each side frame 3A) being pushed forward. Be moved. Therefore, even if the shape of the long hole 4C1 is not raised, the ottoman 4 is efficiently moved diagonally forward (in the direction of raising the footrest position) by the movement of the transmission member (each side frame 3A of the seat cushion 3). ) Can be rotated upward while moving.

  Then, the structure of the vehicle seat 1 of Example 2 is demonstrated using FIGS. In addition, in a present Example, about the location which becomes the substantially same structure and effect | action as the vehicle seat 1 shown in Example 1, the same code | symbol is attached | subjected to these, description is abbreviate | omitted, and a different location is explained in detail. I will explain. In this embodiment, as shown in FIGS. 7 to 8, the unfolding and storing operation of the ottoman 4 is performed in conjunction with the operation of moving the seat cushion 3 back and forth regardless of the movement of the seat back 2. It has become. That is, in this embodiment, the operation of tilting the seat back 2 from the normal use position to the comfort posture position and the operation of moving the seat cushion 3 from the normal use position to the comfort posture position are performed separately. Thus, the ottoman 4 is deployed in conjunction with the movement of the seat cushion 3 to the comfort posture position.

  Specifically, the seat cushion 3 is moved back and forth by the electric motor 8 provided between the side frame 3A on the vehicle outer side (or inside) of the seat cushion 3 and the lateral wall 5 (base plate 5B) on the same side. This is done by driving. The electric motor 8 is provided in a state in which the electric motor 8 is rotatably connected to the horizontal wall 5 (base plate 5B) by a connecting pin 8P1, and the feed screwed to a feed screw 8A that rotates by driving of the electric motor 8 is provided. The nut 8B is axially coupled to the rear portion of the side frame 3A of the seat cushion 3 by a coupling pin 8P2. With the above configuration, when the electric motor 8 is driven and the feed screw 8A rotates, the feed nut 8B is fed back and forth, and the side frame 3A of the seat cushion 3 moves back and forth in the same manner as described in the first embodiment. . The tilting operation of the seat back 2 performed separately from the driving may be performed together with the operation of the seat cushion 3 by using another driving device.

  As mentioned above, although embodiment of this invention was described using two Examples, this invention can be implemented with various forms other than the said Example. For example, in the first embodiment, the transmission member that transmits the movement of the seat back 2 to the ottoman 4 is illustrated as a skeleton of the seat cushion 3 (side frame 3A). May be set as a transmission member. However, in this case, the operation of switching the seat cushion to the comfort posture is not interlocked with the movement of the seat back. Further, the transmission member may be a member set separately from the skeleton of the seat cushion as a member for transmitting the movement of the seat cushion to the ottoman.

  In the above embodiment, the long hole 4C1 is formed in the ottoman 4 and the slide pin 5P is provided in the base plate 5B (base). However, a configuration in which a slide pin is set in the ottoman and a long hole is set in the base may be used. Further, in the above-described embodiment, the transmission member (the side frame 3A of the seat cushion 3) is configured such that its front portion (3F) moves obliquely upward and forward in conjunction with the operation of tilting the seat back 2 backward. However, the transmission member may be configured to be moved straight forward. However, in this case, the shape of the long hole that slides the slide pin must be made to rise upward so that the ottoman can be rotated upward in conjunction with the above movement. Note that the space in the height direction becomes bulky.

  In addition, the ottoman may be hingedly connected to the base at a position (for example, a high position) different from the connection point with the transmission member. Even in such a case, the transmission member is pushed forward, whereby the ottoman can be lifted forward from the connection point with the base.
