Description

  The present invention relates to a vehicle seat. More specifically, the present invention relates to a vehicle seat in which a seat body serving as a seating portion is raised from a use position on a floor to a storage position.

  2. Description of the Related Art Conventionally, there is a vehicle seat that can be stowed from a floor and stored in a folded posture. Here, the following Patent Document 1 discloses a seat structure of a type in which a seat body in a folded posture is flipped up and stored to the side of the vehicle. In this disclosure, the seat body is hinged so that one side of the seat cushion serving as a seating portion can be rotated up and down with respect to the floor by a hinge mechanism.

  In the seat body, the other side of the seat cushion described above is supported by the lock device so as to be detachable from the floor. As a result, the seat body is normally held in a posture of lying on the floor by engagement with the floor. When the seat body is stored, the seat body is disengaged from the floor so that the seat body is raised from the floor by the urging force of the spring member assembled in the hinge mechanism and stored.

JP 2007-283963 A

  However, in the related art disclosed above, the seat body is raised to the retracted position by the urging force of the spring member when retracted. Therefore, since the seat body is in the retracted state even if it is not locked at the retracted position, the user may forget the operation of locking the seat body at the retracted position.

  The present invention has been devised as a solution to the above-described problem, and the problem to be solved by the present invention is to perform a tilting rotation that rotates the seat body between the use position and the storage position. It is intended to be temporarily stopped at a position in the middle of the rotation without performing the operation.

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 a seat body serving as a seating portion is raised from a use position on a floor to a storage position, and includes a hinge mechanism, leg members, and an operation cable. The hinge mechanism hinges the seat body so that the seat body can be rotated upside down. The leg member is provided on the lower side of the seat body so that it can be folded and unfolded. The operation cable pulls the leg member with the rotation of the seat body in the standing direction or the lying down direction, and pulls the leg member against the rotational biasing force applied in the unfolding direction or the folding direction. The operation cable is connected to the leg member and the floor, and the route of the operation cable is hung on a guide provided on the seat body. The operation cable is constantly tensioned by receiving a rotational urging force applied to the leg member in the deployment direction or the folding direction. It is assumed that it was in the state of routing. Between the operation cable and the guide, the operation cable is attached to the guide by the movement of the operation cable sliding on the guide as the seat body is rotated up and down, so that the operation cable slides in at least one direction. Sliding regulating means for regulating is provided. The sliding restriction state of the operation cable by the sliding restricting means is released when an operation force is applied to the operation cable in the direction in which the sliding is restricted.

  According to the first aspect of the invention, when the seat body rotates in the standing direction or the lying down direction, the operation cable is pulled, and the leg member is pulled in the direction opposite to the unfolding direction or the folding direction in which the leg member is rotationally biased. Operated. At this time, the pulling movement of the operation cable is performed while sliding on the guide, and is stopped at a position where the sliding with respect to the guide is regulated by the sliding regulating means. As a result, the rotational movement of the seat body in the standing direction or the lying down direction is stopped at an intermediate position. Then, the rotation prevention state of the seat body is released by, for example, pressing the seat body in the rotation-stopped direction and applying an operation force to the operation cable in a direction in which sliding is restricted. In this way, the up-and-down rotation that rotates the seat body between the use position and the storage position can be temporarily stopped at a position in the middle of the rotation without performing any operation.

  Next, according to a second aspect, in the first aspect described above, the seat body is normally urged in an upright rotational direction by an urging force of an urging member hooked between the seat body and the floor. . The urging force of the urging member is set to a magnitude that can overcome the weight of the seat body and raise the seat body from the use position to the retracted position. The sliding restriction state of the operation cable by the sliding restriction means is maintained by the urging force by the urging means, but is released by applying a separate operating force in the direction to rotate the seat body upright. Is done.

  According to the second aspect of the present invention, the urging rotation that raises the seat body from the use position on the floor to the storage position is temporarily stopped at the position where the slide restriction with respect to the guide of the operation cable is performed by the slide restriction means. And this rotation stop state is cancelled | released by applying the separate operation force of the direction which raises a sheet | seat main body. As a result, the standing rotation due to the urging of the seat body can be temporarily stopped at a stage before reaching the storage position, and the operation of raising the seat body from the position to the storage position is continuously performed by a simple operation such as pressing. be able to.

  Next, a third invention is the above-described first or second invention, wherein the operation restriction of the operation cable by the slide restriction means is such that the protrusion formed on the operation cable has a tension in which the operation cable is tensioned. Thus, the structure is such that it enters into the recess formed in the guide and is hooked.

  According to the third aspect of the present invention, the sliding restricting means for restricting the sliding of the operation cable is formed as an engagement structure between the protrusion formed on the operation cable and the recess formed on the guide. It can be formed simply and in a small size. Then, by adjusting the shape and size of the protrusions and recesses, the sliding restriction force of the operation cable can be adjusted relatively easily.

Next, according to a fourth aspect, in the third aspect described above, the protrusion formed on the operation cable is formed as a spherical body passing through the center of the axis of the operation cable.
According to the fourth aspect of the present invention, since the protrusion formed on the operation cable is a spherical body, the protrusion always remains in the guide recess in a constant manner even when the operation cable slides in a twisted state. Enter and hang. Therefore, the sliding restriction of the operation cable by the sliding restriction means can be stably performed.

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

  First, the configuration of the vehicle seat according to the first embodiment will be described with reference to FIGS. Here, in FIG. 2, the overall structure of the vehicle seat is represented by a perspective view. In this vehicle seat, a seat body 1 serving as a seating portion includes a seat back 2 serving as a backrest and a seat cushion 3 serving as a seating portion. Here, the seat back 2 is connected to the rear end portion of the seat cushion 3 via reclining devices 4 and 4 that function as a rotation-retaining device at the lower ends of both sides thereof.

  The reclining devices 4 and 4 are normally held in a locked state in which the backrest angle of the seat back 2 is fixed. And each reclining device 4 and 4 performs the operation which pulls the operation lever L provided in the position of the bottom rear end side of seat cushion 3 to the back side, and those lock states are canceled all at once. As a result, the fixed state of the backrest angle of the seat back 2 is released, so that the seat back 2 can be folded forward around the axis of each reclining device 4, 4 and folded into the upper surface of the seat cushion 3.

  In addition, since the basic structure of each reclining apparatus 4 and 4 is a well-known structure disclosed by literature, such as Unexamined-Japanese-Patent No. 2002-360368, these detailed description shall be abbreviate | omitted. By the way, the seat body 1 is hinge-connected so that the right side portion of the seat cushion 3 (left side portion in the drawing in FIG. 2) can be rotated up and down with respect to the floor F by the hinge mechanism 10.

  Accordingly, as shown in FIGS. 1 and 3 to 4, the seat main body 1 is rotated upside down between the use position on the floor F and the storage position raised to the side of the vehicle by the hinge mechanism 10. It is in a state that can be done. Here, the hinge mechanism 10 is pivotally supported so that the movable member 12 integrally fixed to the seat cushion 3 can be rotated by the connecting shaft 13 with respect to the fixed member 11 integrally fixed to the floor F. It is a connected structure.

  A torsion spring 14 wound around the connecting shaft 13 is hooked between the fixed member 11 and the movable member 12. Here, the torsion spring 14 corresponds to the biasing member of the present invention. The torsion spring 14 is assembled in a state in which it is pre-twisted, and the movable member 12 is always urged to rotate with respect to the fixed member 11 in a direction in which the seat cushion 3 is raised from the floor F. . Specifically, the rotational biasing force of the torsion spring 14 is set to a magnitude that can overcome the weight of the seat body 1 and raise the seat body 1 from the use position to the retracted position.

  Returning to FIG. 2, the seat body 1 is supported from the lower side by a plate-like leg member 5 in which the left side portion (the right side portion toward the paper surface) of the seat cushion 3 is erected toward the floor F. Has been. Here, the lower edge portion of the leg member 5 is provided with locking devices 20 and 20 which are detachably operated with respect to the strikers S and S fixedly installed on the floor F at two positions in the front and rear sides thereof. It has been. Here, the lock structure of each locking device 20 will be described in detail with reference to FIGS.

  That is, as shown in FIG. 7, the locking device 20 includes a base plate 21 integrally connected to the leg member 5, a latch 22 and a pole 23 rotatably supported by the base plate 21, The tension spring 24 is hooked between the latch 22 and the pole 23. The locking device 20 is configured to engage and lock the latch 22 with the striker S when the striker S is pushed into a receiving port 21 </ b> A formed in the base plate 21.

  Here, the base plate 21 is composed of a set of two sheets, and components such as a latch 22 are assembled between the two plates. Next, the latch 22 is rotatably connected to the base plate 21 by a support shaft 22E. Then, the latch 22 receives a biasing force of the tension spring 24 that is normally hooked between the hook portion 22C and the hook portion 23C of the pole 23, and is in a state of being rotationally biased counterclockwise in the figure. The posture of the initial position that is in contact with the stopper 21B formed on the base plate 21 is maintained.

  The latch 22 includes an upper jaw 22A that protrudes into the mouth of the receiving port 21A formed in the base plate 21 and a receiving port 21A when the latch 22 rotates clockwise from the initial position. The lower jaw 22 </ b> B (see FIG. 8) that moves so as to close the mouth is formed. Further, the latch 22 is formed with a corner portion 22D that engages with the claw portion 23B formed on the pole 23 when the latch 22 rotates clockwise from the initial position.

  On the other hand, the pole 23 is rotatably connected to the base plate 21 by a support shaft 23E. The pole 23 is normally pushed by the corner 22D of the latch 22 in a state of being urged by rotation in the clockwise direction in the figure by receiving the urging force of the tension spring 24 that is hooked between the pawl 23 and the latch 22 described above. It is held in the posture state of the applied initial position. The pawl 23 has an operating arm 23A connected to the end of the release cable CA that is connected to the operating lever L and is pulled, and a corner of the pawl 23 when the latch 22 rotates clockwise from the initial position. A claw portion 23B that engages with the portion 22D is formed.

  Accordingly, as shown in FIG. 7, the lock device 20 having the above-described configuration has the latch 22 that exposes the upper jaw 22A in the mouth by the movement of the striker S being pushed into the receiving port 21A of the base plate 21. It is pushed around. As a result, as shown in FIG. 8, the latch 22 is brought into a state in which the claw portion 23B of the pole 23 is attracted to the corner portion 22D by the urging force of the tension spring 24 and is locked to each other. Is locked. Then, along with this clockwise rotation, the lower jaw 22B moves in the form of wrapping behind the striker S and closes the receiving port 21A. As a result, the striker S is held in an engagement locked state by the latch 22 inside the receiving port 21A.

  That is, the lock device 20 having the above-described configuration is in a lockable state in which the striker S can be engaged and locked by the movement of the striker S being relatively pushed before the release cable CA is pulled. Then, when the release cable CA is pulled, the locking device 20 is operated by operating the operating arm 23A and rotating the pole 23 counterclockwise as shown in FIG. Thereby, the latching state of the claw part 23B of the pole 23 and the corner part 22D of the latch 22 is released, and the latch 22 rotates counterclockwise by the urging force of the tension spring 24.

  As a result, the striker S is discharged from the receiving port 21A so as to be pushed out by the upper jaw 22A of the latch 22, and the engagement locked state of both is released. Then, when the pulling operation of the release cable CA is released, the pole 23 is again pressed against the corner portion 22D of the latch 22, and the lock device 20 can be engaged and locked with the striker S again. Returned to

  Therefore, as shown in FIG. 2, the seat body 1 always has the floor F by the engagement lock between the lock devices 20, 20 and the strikers S, S before the operation of releasing the operation lever L. It is held in the upper use position. The seat body 1 is operated to release the operation lever L, the reclining devices 4 and 4 are unlocked, the seat back 2 is moved forward, and the locking devices 20 and 20 are engaged. When the lock is released, as shown in FIGS. 3 to 4, it is raised toward the vehicle side about the connecting shaft 13 by the urging force of the winding spring incorporated in the hinge mechanism 10. .

  Here, the seat body 1 is provided with a mechanism for operating the leg member 5 so as to be folded into the bottom surface portion of the seat cushion 3 in conjunction with the movement raised from the floor F described above. With this operation mechanism, the seat body 1 is temporarily stopped in its raising rotation at a midway position before reaching the storage position shown in FIG. Next, the configuration of this operation mechanism will be described in detail.

  That is, as shown in FIG. 1, the leg member 5 is pivotally connected to the frame portion of the seat cushion 3 by the connecting shaft 5 </ b> R so that the upper edge portion of the standing plate shape is rotatably supported. As a result, the leg member 5 has an unfolded position in which the plate shape is erected downward from the bottom surface of the seat cushion 3 as shown in the figure, and as shown in FIG. The plate shape can be folded and rotated between the folding position where the plate shape is folded in accordance with the shape of the bottom surface portion of the seat cushion 3.

  A torsion spring 5S wound around the connecting shaft 5R is hooked between the leg member 5 and the seat cushion 3. The torsion spring 5S is assembled in a pre-twisted state, and is urged in a direction in which the leg member 5 is always deployed and rotated to the deployed position. As shown in FIG. 1, a flexible wire-shaped operation cable 7 is connected between the leg member 5 and the fixing member 11 of the hinge mechanism 10.

  The operation cable 7 has one end 7 </ b> A on the right side shown in the figure connected to the fixing member 11 and the other end 7 </ b> B on the left side shown in the figure connected to the leg member 5. Specifically, one end 7 </ b> A of the operation cable 7 is arranged and set at a position spaced apart from the connecting shaft 13 of the hinge mechanism 10 on the lower side in the figure. The operation cable 7 is routed through the inside of the bottom side of the seat cushion 3, and two guide paths 8 are made of resin guides 8 fixedly installed on the skeleton of the seat cushion 3, 9 is routed in a state where the route is guided by 9.

  Here, as shown in FIG. 5, the guides 8 and 9 are formed in the same shape as each other, and are arranged so as to be reversed up and down. The guides 8 and 9 are formed on the upper or lower surface with concave guide path surfaces 8A and 9A on which the operation cable 7 can be hooked so as to be received from the upper or lower surface side. The guide path surfaces 8A and 9A are configured to guide the operation cable 7 so that the operation cable 7 does not come off sideways due to the concave shape. The guide path surfaces 8A and 9A are formed in curved curved shapes having no protrusions for guiding so that the operation cable 7 can smoothly slide in the longitudinal direction (axial direction).

  As shown in FIG. 1, the operation cable 7 described above is always guided by the guide path surface of each of the guides 8 and 9 due to the biasing force of the leg member 5 rotating in the deployment direction by the biasing force of the torsion spring 5S. It is set as the tensioned wiring state pressed by 8A and 9A. Therefore, as shown in FIG. 3, the operation cable 7 slides on the guide path surfaces 8A and 9A of the guides 8 and 9 by the movement of the seat body 1 raised from the floor F. Then, the leg member 5 is pulled by the other end 7B so as to be pulled in the folding direction against the bias.

  The biasing force of the torsion spring 5S that biases the leg member 5 in the deploying direction is set to be sufficiently smaller than that of the torsion spring 14 assembled to the hinge mechanism 10. Therefore, even if the urging force of the torsion spring 5S is applied, the seat body 1 is smoothly raised from the floor F only by the urging force of the torsion spring 14 assembled to the hinge mechanism 10. The operation cable 7 holds the leg member 5 in the retracted position along the bottom surface of the seat cushion 3 by raising the seat body 1 to the retracted position shown in FIG.

  Incidentally, as shown in FIG. 5, the above-described operation cable 7 is integrally formed with a protrusion 7 </ b> C that protrudes partially from the wire shape into a spherical shape. Further, in the guide 9 shown on the right back side in the figure, a concave portion 9B capable of receiving the above-described spherical protrusion 7C is partially formed on the guide path surface 9A. The recess 9B is formed at the end position on the receiving side of the guide path surface 9A.

  Here, the protrusion 7C of the operation cable 7 described above is positioned between the guides 8 and 9 when the seat body 1 is in the initial position in the use position on the floor F as shown in FIG. Is formed and arranged. Then, the position of the protrusion 7 </ b> C varies as the operation cable 7 is pulled by the standing rotation of the seat body 1. As shown in FIG. 3, the protrusion 7 </ b> C enters the recess 9 </ b> B formed in the guide 9 described above at a midway position before the seat body 1 reaches the storage position, and hooks with the recess 9 </ b> B. To wear.

  The hooking force that the projection 7C enters into the recess 9B and hooks is applied so that the operation cable 7 is strongly hooked by the action of a tensile force that receives the unfolding biasing force of the leg member 5 and is tensioned. 7 acts as a resistance force that regulates sliding in the traveling direction with respect to the guide 9. As a result, the seat body 1 is temporarily stopped from being erected and rotated at the position where the projection 7C and the recess 9B are engaged. Then, the rotationally stopped state of the seat body 1 is released by applying a forcing operation force in the forward direction to the operation cable 7 by, for example, applying a pressing force in the standing rotation direction to the seat body 1. Can do.

  Specifically, as shown in FIG. 6, the projecting portion 7 </ b> C has a spherical shape by applying an operation force in the traveling direction (in the illustrated arrow direction) to which the sliding of the operation cable 7 is restricted. The concave surface 9B is overcome by the curved surface, and the hooked state of both is released. As a result, as shown in FIG. 4, the seat body 1 resumes the standing rotation due to the urging of the torsion spring 14 and is raised to the retracted position.

  When the seat body 1 is raised to the retracted position, for example, a hook provided at the tip of a strap (not shown) provided on the seat body 1 is hooked on the assist grip on the side wall of the vehicle. To fix. Thereby, even if the seat body 1 is subjected to a load action such as vibration during traveling of the vehicle or the like, it is possible to prevent the seat body 1 from being overturned on the floor F.

  Note that the above-described rotation stopping function of the seat body 1 does not work during the overturning rotation in which the seat body 1 is brought down on the floor F from the storage position. That is, as can be seen with reference to FIG. 6, the recess 9B formed in the guide 9 is pulled in the direction opposite to the arrow direction in which the operation cable 7 is illustrated, so that the projection 7C is recessed from the right side in the drawing. This is because the protrusion 7C is formed in a shape that allows the protrusion 7C to escape from the recess 9B as it is.

  As described above, according to the vehicle seat of the present embodiment, when the seat body 1 rotates in the standing direction, the operation cable 7 is pulled and the leg member 5 is rotated and biased, which is opposite to the deployed direction. Pulled in the direction. At this time, the pulling movement of the operation cable 7 is performed while sliding on the guide 9, and the sliding with respect to the guide 9 is regulated by the sliding regulating means formed by the hooking structure of the projection 7C and the recess 9B. (See FIG. 3).

  As a result, the rotational movement of the seat body 1 in the standing direction is stopped at an intermediate position. The rotation stop state of the seat body 1 is released by, for example, pressing the seat body 1 in the rotation-stopped direction and applying an operation force to the operation cable 7 in a direction in which sliding is restricted. . In this manner, the upside-down rotation for rotating the seat body 1 between the use position and the storage position can be temporarily stopped at a position in the middle of the rotation without any operation.

  Therefore, since the seat body 1 is not lifted up to the retracted position in a single operation by the release operation of the operation lever L, the user cannot seat the seat body 1 at the retracted position. Can be recognized as being not fixed at the storage position. Then, the sheet main body 1 that is prevented from rotating at this midway position can be raised to the storage position by a simple operation that applies an operating force in the direction in which the sheet main body 1 is raised. Accordingly, when a separate fixing operation is required after the seat body 1 is raised to the storage position, the seat body 1 can be raised from the storage intermediate position to the storage position without requiring a troublesome operation. Forgetting to perform the fixing operation can be prevented.

  In addition, since the sliding restricting means for restricting the sliding of the operation cable 7 is formed as an engagement structure between the protrusion 7C formed on the operation cable 7 and the recess 9B formed on the guide 9, this structure is simplified. And it can be formed small. Then, by adjusting the shape and size of the protrusion 7C and the recess 9B, the adjustment of the sliding restriction force of the operation cable 7 can be performed relatively easily.

  Since the protrusion 7C formed on the operation cable 7 is a spherical body, even if the operation cable 7 slides in a twisted state, the protrusion 7C always enters the recess 9B of the guide 9 in a certain manner. Hang on. Therefore, the sliding regulation of the operation cable 7 by the sliding regulation means can be performed stably.

  Although the embodiment of the present invention has been described with one example, the present invention can be implemented in various forms in addition to the above example. For example, as shown in FIG. 9, a hooking structure of a recess 9 </ b> C formed on the guide 9 and a protrusion 7 </ b> C formed on the operation cable 7 is formed so as to restrict bidirectional sliding of the operation cable 7. May be. Further, the projection 7C formed on the operation cable 7 does not necessarily have to be formed in a spherical shape, and may be formed in a shape having an inclined surface or a curved surface such as a triangular body or a cylindrical body. Good.

  In addition, the structure in which the movement of the seat body 1 raised from the floor F is stopped halfway as the sliding restriction means is shown. However, the movement of the seat body being pushed down from the storage position onto the floor is stopped halfway. You may comprise as follows. In this case, for example, the leg member is always urged in the folding direction, and the operation cable is pulled by the movement in which the seat body is collapsed, and the leg member is expanded and rotated. Thus, the sliding restriction means can be made to function.
