  However, in the conventional technology as described above, when storing the seat or when deploying the stored seat to be usable, it is necessary to perform an operation of sliding the seat backward and an operation of standing up with respect to the vehicle body, There was room for improvement in operability.

  An object of the present invention is to obtain a seat storage structure in which switching operability between a use posture and a storage posture of a seat cushion is favorable in consideration of the above fact.

  In order to achieve the above object, the seat storage structure according to the first aspect of the invention is supported by the slide support means so as to be slidable in the longitudinal direction of the vehicle body, and is rotated around an axis along the longitudinal direction of the vehicle body by the rotation support means. A seat cushion that is supported in a movable manner so that an occupant can be seated, a seat cushion that slides in the front-rear direction of the vehicle body with respect to the use posture, and that can be stood up with respect to the vehicle body, and the seat cushion is used or retracted When switching to a posture, the seat cushion is provided with interlocking means for interlocking the slide operation guided by the slide support means and the rotation operation guided by the rotation support means.

  In the seat storage structure according to claim 1, when the seat cushion is switched from the use state in which the occupant can be seated to the storage state, for example, the seat cushion is slid to the storage side in the vehicle longitudinal direction, or the seat cushion is It turns to the storage (standup) side around the axis along the direction. Then, the interlocking means acts, and the seat cushion rises by rotating to the storage side with respect to the vehicle body along with the sliding to the storage side in the longitudinal direction of the vehicle body, or the vehicle body according to the rotation to the storage side with respect to the vehicle body. Slide to the storage side in the front-rear direction and switch to the storage state. Further, for example, the storage state is switched to the use state by the reverse operation.

  In this seat storage structure, the sliding movement in the longitudinal direction of the vehicle body in which the seat cushion is guided by the sliding support means and the rotational movement in the longitudinal direction along the longitudinal direction of the vehicle body in which the seat cushion is guided by the rotational support means are linked. Since they are interlocked by the action of the means, the use state and the retracted state of the seat cushion can be switched without independently performing the two operations of sliding and rotating.

  Thus, in the seat storage structure according to the first aspect, the operability of switching between the use state and the storage state of the seat cushion is good. The present invention includes a configuration for operating and driving the interlocking means in addition to a configuration for applying an operating force to the seat cushion exemplified above (the seat cushion side of the slide support means or the rotation support means).

  The seat storage structure according to a second aspect of the present invention is the seat storage structure according to the first aspect, wherein the interlocking means supports a part of a sliding operation force in the vehicle body front-rear direction input to the seat cushion.

A connecting member to be obtained.

  In the seat storage structure according to claim 3, the connecting member is slid as described above by changing the posture so that the projection length in the longitudinal direction of the vehicle body changes in accordance with switching between the use posture and the storage posture. A part of the force or the turning operation force is converted into a turning force or a sliding force. As a result, the seat cushion slides in the longitudinal direction of the vehicle body by the difference in the projection length, and rotates around the axis along the longitudinal direction of the vehicle body due to the posture change of the connecting member, so that the use posture and the retracted posture are switched. By using this connecting member, the slide operation and the rotation operation having a large operation range can be linked in a compact configuration.

  A seat storage structure according to a fourth aspect of the present invention is the seat storage structure according to the second or third aspect, wherein one end side of the seat cushion in the seat width direction is the slide support means via the rotation support means. It is supported by.

  In the seat storage structure according to claim 4, since the rotation support means is provided on the seat cushion side of the slide support means located on one end side of the seat cushion in the seat width direction (vehicle width direction), the structure as a whole is provided. It can be configured simply and compactly.

  The sheet storage structure according to a fifth aspect of the present invention is the seat storage structure according to any one of the second to fourth aspects, wherein the interlocking means is located on a side of the wheel house in a use posture. When a rotational operation force about an axis in the longitudinal direction of the vehicle body is input to the cushion, the seat cushion is switched to the retracted posture in which the seat cushion is turned to the side of the vehicle interior at the rear of the wheel house. The slide operation guided by the rotation and the rotation operation guided by the rotation support means are interlocked.

  In the seat storage structure according to claim 5, when the rotational force is applied around the longitudinal axis of the vehicle body so that the seat cushion stands up toward the side of the vehicle interior, the seat cushion is supported by the action of the interlocking means. It is guided by the means and is guided by the slide while rotating around the longitudinal axis of the vehicle body, and slides backward in the longitudinal direction of the vehicle body. From the lateral use posture of the wheel house to the retracted posture behind the wheel house. Accordingly, the sheet can be stored at a position avoiding the wheel house with a simple operation (work).

  The sheet storage structure according to a sixth aspect of the present invention is the seat storage structure according to any one of the second to fourth aspects, wherein the interlocking means is located on a side of the wheel house in a use posture. When a sliding operation force in the longitudinal direction of the vehicle body is input to the cushion, the seat cushion is guided to the slide support means so that the seat cushion is switched to a retracted posture facing the vehicle interior side behind the wheel house. The slide operation and the rotation operation guided by the rotation support means are interlocked.

  In the seat storage structure according to claim 6, when a sliding force is applied backward in the vehicle longitudinal direction so that the seat cushion slides backward, the seat cushion is guided by the action of the interlocking means and is moved in the vehicle longitudinal direction. While being slid rearwardly, it is guided by the rotation support means and is rotated about the longitudinal axis of the vehicle body, and from the side use position of the wheel house to the retracted position behind the wheel house.

Therefore, it is easy to switch the seat cushion usage posture to the retracted posture. Here, since the seat storage structure has interlocking means, the seat cushion can be slid and rotated by one driving means, and the structure is simplified. Note that, for example, the driving force of the driving unit may be used only when switching from one of the use posture and the storage posture to the other.

  As described above, the seat storage structure according to the present invention has an excellent effect that the switching operability between the use posture and the storage posture of the seat cushion is good.

  A vehicle seat 10 to which a seat storage structure according to a first embodiment of the present invention is applied will be described with reference to FIGS. 1 to 4. It should be noted that arrows FR and UP appropriately shown in the drawings respectively indicate the forward direction (traveling direction) and the upward direction of the vehicle to which the vehicle seat 10 is applied, and the arrow OUT indicates the vehicle width that matches the seat width direction. The outside of the direction is shown.

  FIG. 4A shows a schematic overall configuration of the vehicle seat 10 in a perspective view. As shown in this figure, the vehicle seat 10 supports a seat cushion 12 on which an occupant of a mounted automobile is seated, and an upper body of the seated occupant connected to the rear end of the seat cushion 12 from behind. The seat back 14 is provided. The vehicle seat 10 is a rear seat, and the posture that allows the occupant to sit on the side of the rear wheel house 16 (inner side in the vehicle width direction) that protrudes into the passenger compartment is the use posture (seat state). It is said that.

  The vehicle seat 10 can be switched from the use posture described above to the retracted posture shown in FIG. In the vehicular seat 10 in the retracted position, the seat back 14 is superimposed on the seat cushion 12, and the inner end portions 12A and 14A, which are located in the vehicle width direction in the use posture, are located above the outer end portions 12B and 14B. Standing up (bounced up) to be located at. Thereby, in the motor vehicle to which the vehicle seat 10 is applied, a space-up state in which the cargo space is enlarged can be taken. Hereinafter, the switching structure between the use posture (seat state) and the storage posture (space-up state) will be specifically described.

  The seat back 14 is connected at its lower end to the rear end of the seat cushion 12 via a reclining mechanism (not shown). Although a detailed description is omitted, the reclining mechanism is configured to be able to move the seat back 14 forward to a position where it substantially comes into contact with the seat cushion 12 in the unlocked state and to maintain this forward tilted posture.

  As shown in FIG. 1, the seat cushion 12 is configured by providing a cushion material 20 on a seat cushion frame 18. The seat cushion frame 18 has an outer end portion 18A in the width seat direction that coincides with the vehicle width direction and is supported by the vehicle body via a seat hinge 22 as a rotation support means and a seat slider 24 as a slide support means. Yes. The seat slider 24 includes a lower rail 26 fixed to the vehicle body floor F, and an upper rail 28 provided on the lower rail 26 so as to be slidable in the vehicle longitudinal direction. In the seat slider 24, the use posture described above is the front side movement limit (in the vicinity thereof), and the retracted posture is the rear side movement limit (in the vicinity thereof).

  The seat hinge 22 includes a hinge bracket 30 fixed to the upper rail 28, and a hinge arm 34 rotatably connected to the hinge bracket 30 via a hinge shaft 32 having an axis along the vehicle body longitudinal direction. ing. The end of the hinge arm 34 opposite to the hinge shaft 32 side is fixed to the outer end 18 </ b> A of the seat cushion frame 18. In this embodiment, a pair of front and rear seat hinges 22 having a coaxial hinge shaft 32 are provided, and the seat cushion frame 18 is supported by the seat slider 24 via these seat hinges 22.

  In addition, a pair of front and rear leg support brackets 36 are fixed to the inner side in the vehicle width direction by the seat hinge 22 (hinge shaft 32) of the seat cushion frame 18, and the pair of front and rear leg support brackets 36 are respectively paired with the vehicle body. The leg plate 40 is swingably supported via a swing shaft 38 disposed coaxially along the front-rear direction. The leg plate 40 is engaged with a striker 42 provided on the vehicle body floor F in a substantially upright posture with respect to the vehicle body floor F. In this engaged state, the vehicle seat 10 (seat cushion 12) is prohibited from rotating around the hinge shaft 32 and sliding in the longitudinal direction of the vehicle body.

  The leg plate 40 is configured to support the seat cushion 12 (seater) with respect to the vehicle body together with the seat hinge 22 in a state of being substantially upright with respect to the vehicle body floor F. Further, the vehicle seat 10 is provided with a lock mechanism (not shown) for maintaining the engagement between the leg plate 40 and the striker 42 when taking a use posture. Therefore, in order to switch the vehicle seat 10 to the retracted posture, an unlock operation unit (not shown) is operated. The leg plate 40 is folded along the upright seat cushion 12 in the retracted position. Further, the leg plate 40 is configured to engage with the striker 42 as the seat cushion 12 is switched from the retracted position to the used position and is automatically locked by the lock mechanism.

  As described above, in the vehicle seat 10, the seat back 14 is moved forward with respect to the use posture until the seat back 14 abuts (overlaps) with the seat cushion 12, and the seat cushion frame 18 is moved to the arrow A around the hinge shaft 32 (FIG. 1). The position (posture) that is caused to rotate to a substantially vertical position with respect to the vehicle body floor F and move to the rearward movement limit of the seat slider 24 is the retracted posture. In this retracted position, as shown in FIG. 4B, the folded vehicle seat 10 is positioned behind the wheel house 16 and faces the deck side trim 44 that forms the side of the vehicle interior. .

  The vehicle seat 10 serves as an interlocking means and a connecting member for interlocking the pivoting motion around the hinge shaft 32 guided by the seat hinge 22 and the sliding motion in the longitudinal direction of the vehicle body guided by the seat slider 24. The damper stay 46 is provided. The damper stay 46 has a rear end 46A, which is one end in the longitudinal direction, connected to a floor anchor bracket 48 fixed to the vehicle body floor F in a ball joint shape, and can be rotated in each direction with respect to the floor anchor bracket 48. It is said that. A front end 46B of the damper stay 46 is connected to a damper bracket 50 fixed to the front portion 18B of the seat cushion frame 18 in a ball joint shape, and can be rotated in each direction with respect to the damper bracket 50. ing. The damper stay bracket 50 is disposed so as to be separated from the hinge shaft 32 inward in the vehicle width direction.

  As a result, the front end 46B of the damper stay 46 is located on the upper side in the vehicle vertical direction and on the inner side in the vehicle width direction when the vehicle seat 10 is in the retracted position (see solid line) as shown in FIG. It is supposed to be located in. Specifically, the vertical projection dimension H2 (vertical distance from the rear end 46A) in the retracted posture of the vehicle seat 10 is larger than the vertical projection dimension H1 in the usage posture. (H2> H1), the projected dimension W2 in the seat width direction (the distance in the vehicle width direction from the rear end 46A) in the retracted position of the vehicle seat 10 is smaller than the projected dimension W1 in the seat width direction in the usage position. (W2 <W1).

  The damper stay 46 has a longitudinal projection length L2 (a distance in the longitudinal direction from the rear end 46A) in the retracted posture of the vehicle seat 10 that is smaller than a longitudinal projection length L1 in the usage posture. (L2> L1), the support position of the rear end 46A with respect to the floor anchor bracket 48 is set. Further, the damper stay 46 has the front end 46B always above the rear end 46A in the vertical direction of the vehicle body and the center side in the seat width direction (inner side in the vehicle width direction) regardless of the posture change between the use posture and the retracted posture. It is supposed to be located in. That is, in the damper stay 46, the rotation angle in front view around the rear end 46A between the use posture and the retracted posture of the front end 46B is set to be smaller than 90 °, so that the projection length described above is set. L2 <L1 is realized.

  Thereby, in the vehicle seat 10, when the seat cushion 12 in the use posture is rotated in the direction of the arrow A, the difference (L1-L2) between the projection length L1 in the use posture of the damper stay 46 and the projection length L2 in the retracted posture. Therefore, the seat cushion 12 slides backward to reach the retracted position. Further, in the vehicle seat 10, the damper stay 46 is in the use posture of the damper stay 46 when the vehicle seat 10 taking the retracted posture is rotated in the direction of the arrow B (see FIGS. 1 and 2) opposite to the arrow A. The seat cushion 12 slides forward and shifts to the use posture by the difference (L1-L2) between the projection length L1 and the projection length L2 in the retracted posture.

  In other words, the damper stay 46 is configured to convert a part of the turning force in the arrow A direction or the arrow B direction input to the seat cushion 12 into a sliding force in the longitudinal direction of the vehicle body. It is also possible to push the seat cushion 12 backward from the use posture and rotate it in the direction of arrow A, and push the seat cushion 12 forward from the retracted posture and rotate it in the direction of arrow B.

  The damper stay 46 described above can be expanded and contracted in the longitudinal direction by a slight amount by deformation of a built-in elastic member such as rubber, and absorbs dimensional errors, assembly errors, rattling, and the like. This expansion / contraction amount is sufficiently small with respect to the difference in projection length in the front-rear direction (L1-L2). Such dimension absorbing portions are provided between the damper stay 46 and the floor anchor bracket 48 or the damper bracket 50, between the floor anchor bracket 48 and the vehicle body floor F, and between the damper bracket 50 and the seat cushion frame 18. In these cases, a simple rod can be used as the interlocking means or the connecting member in place of the damper stay 46.

  Next, the operation of the first embodiment will be described.

  In the vehicle seat 10 having the above-described configuration, the occupant can be seated in the seat state in the usage posture shown in FIGS. 1 and 4A. When the vehicle seat 10 is stored, first, the reclining mechanism is unlocked and the seat back 14 is moved forward and brought into contact with (overlapping) the seat cushion 12. Next, the lock release operation portion is operated to release the engagement lock state between the leg plate 40 and the striker 42, and the vehicle width direction inner end portion 12A of the seat cushion 12 on which the seat back 14 is superimposed is lifted upward.

  Then, the seat cushion 12 is guided in the rotational direction around the hinge shaft 32 together with the seat back 14 and is rotated in the arrow A direction. At this time, the damper stay 46 changes its posture while displacing the front end 46B upward and outward in the vehicle width direction, and moves the front end 46B rearward in the vehicle longitudinal direction. As a result, the seat cushion 12 slides backward while rotating in the direction of arrow A, and as shown in FIG. 4 (B), the seat cushion 12 takes a stowed upright position along the deck side trim 44 behind the wheel house 16. Transition to the up state. Thereby, in the automobile on which the vehicle seat 10 is mounted, it is possible to secure a wide cargo space and obtain a good rear view in a space-up state.

  Specifically, as shown in FIG. 7A, in the comparative example seat 100 that is stood and stored inside the wheel house 16 in the vehicle width direction, the cargo compartment width becomes narrow, and FIG. As shown in FIG. 7, in the comparative example sheet 110 stored above the wheel house 16, the side window 52 is blocked as shown in FIG. On the other hand, in the vehicle seat 10, as shown in FIG. 4 (B), in the retracted position, the vehicle seat 10 is positioned behind the wheel house 16 and close to the deck side trim 44. Therefore, a wide cargo space is secured as described above. In addition, a good rear view can be obtained. Note that switching of the vehicle seat 10 from the retracted position to the used position is performed by an operation opposite to the above operation (operation).

  On the other hand, when the vehicle seat 10 is switched from the retracted position to the used position, the seat cushion 12 is rotated together with the seat back 14 in the arrow B direction. Then, the seat cushion 12 moves forward while rotating in the direction of arrow B due to the posture change of the damper stay 46, and shifts to the use posture. Next, when the seat back 14 is raised, the vehicle seat 10 is switched to the use posture, that is, the seat state.

  Here, the vehicle seat 10 includes a damper 46 that links the sliding motion of the seat cushion 12 along the longitudinal direction of the vehicle body with the rotational motion around the hinge shaft 32, and therefore the inner end 12A of the seat cushion 12 is lifted (arrow). The vehicle seat 10 can be moved to the rear of the wheel house 16 by the operation of turning to A). That is, in the vehicle seat 10, the operation of moving the seat cushion 12 backward and the operation of rotating in the direction of the arrow A can be switched to the retracted posture with one operation without being independently performed. Further, switching from the retracted position to the used position can be performed simply by rotating the seat cushion 12 in the arrow B direction.

  Thus, in the vehicle seat 10 to which the seat storage structure according to the first embodiment is applied, the switching operability between the use state and the storage state of the seat cushion 12 is good.

  The damper stay 46 has a structure that converts a part of the rotational force in the direction of arrow A or arrow B into a sliding force to the rear or front (regulates force transmission in the other direction), so only the operation force by the occupant is used. Thus, the sliding motion of the seat cushion 12 along the longitudinal direction of the vehicle body and the pivoting motion around the hinge shaft 32 can be interlocked. Further, since the damper stay 46 constituting the interlocking means is not operated, the seat cushion 12 can be stored by a natural operation of lifting the seat cushion 12.

  In addition, since the damper stay 46 using the difference in projection length is used as the interlocking means, the sliding motion of the seat cushion 12 along the longitudinal direction of the vehicle body and the rotational motion around the hinge shaft 32 are interlocked with a simple and compact structure. Was realized. That is, since switching between the use posture and the storage posture of the vehicle seat 10 has a wide operation range, the use of a cam, a link, or the like as the interlocking means complicates or enlarges the structure. In the working sheet 10, the interlocking means can be realized with a simple and compact structure as described above. In particular, since the seat cushion 12 is supported by the seat slider 24 via the seat hinge 22 on the outer end portion 12B side, the seat storage structure is configured to be compact as a whole in combination with the adoption of the above described damper stay 46. .

(Second Embodiment)
FIG. 5 is a perspective view of a switching mechanism portion (main part) between the use posture and the storage posture constituting the vehicle seat 60 according to the second embodiment of the present invention. As shown in this figure, the vehicle seat 60 includes a drive mechanism 62 as drive means for automatically switching between the use posture and the storage posture, and the vehicle seat 10 according to the first embodiment.

  The drive mechanism 62 includes a feed screw mechanism (not shown). The slide screw constituting the feed screw mechanism is aligned with the upper rail 28 in the longitudinal direction, and is rotatable about the axis and relative to the upper rail 28 in the longitudinal direction. It is supported impossible. A slide nut screwed to the slide screw is fixed to the lower rail 26. The drive mechanism 62 includes a motor actuator 64 capable of rotating in the forward and reverse directions for rotationally driving the slide screw of the feed screw mechanism. The motor actuator 64 is attached to the upper rail 28.

  The drive mechanism 62 described above is configured such that the upper rail 28 slides backward with respect to the lower rail 26 when the motor actuator 64 rotates forward, and the upper rail 28 slides forward with respect to the lower rail 26 when the motor actuator 64 rotates reversely. It is said that. The motor actuator 64 rotates forward when the occupant operates a storage switch (not shown), and rotates reversely when the occupant operates a use switch (not shown). Other configurations of the vehicle seat 60 are the same as the corresponding configurations of the vehicle seat 10.

  In the vehicle seat 60 having the above-described configuration, the occupant can be seated in a seat state where the use posture is taken. When storing the vehicle seat 60, first, the reclining mechanism is unlocked, the seat back 14 is moved forward and brought into contact with (overlapping) the seat cushion 12. Next, the lock release operation unit is operated to release the engagement lock state between the leg plate 40 and the striker 42, and the storage switch (not shown) is turned ON.

  Then, the seat cushion 12 automatically slides back together with the seat back 14 by the power of the motor actuator 64. At this time, the damper stay 46 changes its posture while displacing the front end 46B rearward, and moves the front end 46B upward in the vehicle longitudinal direction and outward in the vehicle width direction. As a result, the seat cushion 12 rotates in the direction of the arrow A while sliding backward, and shifts to a space-up state in which the seat cushion 12 is stood up along the deck side trim 44 behind the wheel house 16. As a result, in the automobile on which the vehicle seat 60 is mounted, as in the first embodiment, in the space-up state, it is possible to secure a wide cargo space and obtain a good rear view.

  Further, when the vehicle seat 60 taking the retracted posture is switched to the use posture, a use switch (not shown) is turned on. Then, the vehicle seat 60 rotates in the direction of arrow B while the seat cushion 12 moves forward together with the seat back 14 by an operation opposite to that at the time of storage, and the seat cushion 12 is switched to the use posture. Next, by causing the seat back 14, the vehicle seat 60 is switched to the use posture, that is, the seat state.

  Here, since the vehicle seat 60 includes the drive mechanism 62 for electrically driving the seat cushion 12, the use posture and the storage posture of the vehicle seat 60 can be switched simply by operating the operation switch. Good properties.

  Further, since the vehicle seat 60 includes a damper 46 that interlocks the pivoting motion around the hinge shaft 32 with the sliding motion of the seat cushion 12 along the longitudinal direction of the vehicle body, the seat cushion 12 is configured using a single motor actuator 64. The drive mechanism 62 that switches between the use posture and the storage posture can be configured. Furthermore, by using the damper stay 46, the structure in which the pivoting movement around the hinge shaft 32 and the sliding movement of the seat cushion 12 along the longitudinal direction of the vehicle body are configured in a simple and compact manner is the first embodiment. It is the same.

(Third embodiment)

As shown in this figure, the vehicle seat 70 is provided with a drive mechanism 72 as drive means for automatically switching between the use posture and the retracted posture, and the structure of the drive mechanism 72 is the second embodiment. This is different from the drive mechanism 62 of the vehicle seat 60 according to the above. The drive mechanism 72 is configured as a linear actuator that also functions as a slide support means, and supports the seat cushion 12 so as to be slidable in the longitudinal direction of the vehicle body with respect to the vehicle body floor F without using the seat slider 24.

  Specifically, the drive mechanism 72 includes a slider shaft 74 that is elongated in the longitudinal direction of the vehicle body. The slider shaft 74 has a front end fixed to the vehicle body floor F via a floor anchor bracket 76 and a rear end fixed to the vehicle body floor F via a floor anchor bracket 48. An intermediate portion excluding the front and rear ends. Is separated from the vehicle body floor F. The front portion of the slider shaft 74 is a slide screw 74A having a feed screw formed on the outer periphery, and the rear portion thereof is a substantially cylindrical slide guide 74B. Further, a slide nut 78 is screwed into the slide screw 74 A of the slider shaft 74, and the slide nut 78 is rotated forward or reverse by a motor actuator 80.

  Further, the seat hinge 22 located on the front side includes a hinge bracket 82 fixed to the motor actuator 80 instead of the hinge bracket 30. The hinge bracket 82 supports the hinge arm 34 (seat cushion frame 18) via the hinge shaft 32, and is movable in the longitudinal direction of the vehicle body through the slide screw 74A. On the other hand, the rear seat hinge 22 includes a hinge bracket 84 instead of the hinge bracket 30.
