Abstract

PROBLEM TO BE SOLVED: To suppress concentration of load when the load which is other than in the rotation direction is applied to an operation member.SOLUTION: A cover 106 is fastened and fixed to a cushion frame 16 in a vehicle seat. Then, when the amount of rocking (movement) of a case 60 (engaging clutch mechanism 48) exceeds a reference value by having a load which is other than in the rotation direction applied to an operation lever 118, a bottom wall 62 of the case 60 is abutted to a bottom wall 114 of a cylinder section 107 of the cover 106 and the sidewall 63 of the case 60 is abutted to a sidewall 110 of the cylinder section 107. Therefore, the load applied (input) to the case 60 (engaging clutch mechanism 48) is dispersed on the cover 106 and transmitted to the cushion frame 16. Thus, concentration of load on a portion of a through-hole 64A of the case 60 can be suppressed.

  The present invention relates to a vehicle seat that adjusts an adjusted mechanism such as a reclining mechanism by operating an operation member.

  A seat shown in Patent Document 1 below includes a reclining plate (operation force transmission mechanism) for transmitting an operation force of an operation lever operated by a seated person to a reclining mechanism (adjusted mechanism), and the operation force. A lifter plate (operation force transmission mechanism) for transmitting to a lifter mechanism (adjusted mechanism), and a switching mechanism that can selectively take a state of transmitting the operation force to the lifter plate and a state of transmitting the operation force to the reclining plate. ing.

  The reclining mechanism and the lifter mechanism can be individually adjusted by pressing the switching knob that constitutes a part of the switching mechanism and rotating the operation lever.

JP 2007-196899 A

  However, in the above seat, the operation lever and the reclining plate are rotatably supported by the support pins, so that a load other than the rotation direction (for example, a load in the rotation axis direction of the operation lever) is temporarily inadvertently caused by carelessness. When applied to the tip, a rotational moment acts on the operation lever, and the load concentrates on the support pin.

  In view of the above fact, an object of the present invention is to provide a vehicle seat that can suppress concentration of load when a load other than the rotation direction is applied to the operation member.

  The vehicle seat according to claim 1 is provided on the seat main body, and is adjusted to be adjustable or adjustable by transmission of an operating force, and the seat main body directly or in other ways. An operation force transmission mechanism that is rotatably provided via a member and that is rotated to transmit an operation force to any of the plurality of adjusted mechanisms, and is provided to be integrally rotatable with the operation force transmission mechanism. An operation member to which a force is applied and fixed to the seat main body, a load other than a rotation direction is applied to the operation member, and the operation force transmission mechanism is moved to come into contact with the operation force transmission mechanism A load transmission member.

  In the vehicle seat according to claim 1, the operating force transmission mechanism is rotatably provided on the seat body directly or via another member, and the operating force transmission mechanism is provided with the operation member so as to be integrally rotatable. ing. The seat body is provided with a plurality of adjusted mechanisms.

  When the operation member is rotated, the operation force transmission mechanism is rotated, and the operation force is transmitted to any of the plurality of adjusted mechanisms. As a result, any of the mechanisms to be adjusted can be adjusted or adjusted.

  Here, a load transmission member is fixed to the seat body. The operation force transmission mechanism and the load transmission member are brought into contact with each other by applying a load other than the rotation direction to the operation member and moving the operation force transmission mechanism. Therefore, at this time, the load applied to the operating force transmission mechanism is distributed to the load transmission member and transmitted to the seat body. In addition, at this time, since the operation force transmission mechanism is held by the load transmission member, the movement of the operation force transmission mechanism is suppressed, and consequently the movement of the operation member is suppressed.

  The vehicle seat according to claim 2 is the vehicle seat according to claim 1, wherein the load transmission member is formed in a cylindrical shape covering the operation force transmission mechanism, and the seat is more than the operation member. The main body side is provided with a cylindrical portion whose outer width is set wider.

  In the vehicle seat according to the second aspect, the load transmission member has a cylindrical portion formed in a cylindrical shape covering the operating force transmission mechanism. Here, in the cylindrical portion, the width of the outer shape is set wider on the seat body side than the operation member. For this reason, for example, the contact portion between the load transmission member and the operation force transmission mechanism is set so that the direction of the load acting from the operation force transmission mechanism to the load transmission member coincides with the extending direction of the side wall of the cylindrical portion. By doing so, the load transmitting member can transmit the load to the seat body while suppressing deformation of the load transmitting member due to the load acting on the load transmitting member.

  According to a third aspect of the present invention, in the vehicle seat according to the second aspect, the load transmitting member includes a fixing portion that protrudes from the cylindrical portion and is fixed to the seat body.

  In the vehicle seat according to claim 3, the load transmitting member is fixed to the seat body at the fixing portion, and the fixing portion projects from the cylindrical portion, and therefore the cylinder on which the load from the operating force transmission mechanism acts. The load transmitting member can be fixed to the seat body outside the portion. Thereby, the load transmission member can receive a load stably.

  A vehicle seat according to a fourth aspect is the vehicle seat according to any one of the first to third aspects, wherein the vehicle seat is provided on the operation member and operated to prevent non-operation of the operation member. A switching member that moves from the operation position to the operation position is provided, the plurality of adjusted mechanisms are first to third adjusted mechanisms, and the operating force transmission mechanism is rotated to one side in the rotation direction. A first operating force transmitting member that transmits an operating force to the first adjusted mechanism and that transmits the operating force to the second adjusted mechanism by being rotated to the other side in the rotation direction; A second operating force transmitting member provided coaxially with the transmitting member and transmitting the operating force to the third adjusted mechanism by being rotated to one side in the rotational direction or the other side in the rotational direction; and integral with the operating member It is made rotatable, and the operation member in the non-operation position of the switching member And a connecting member that connects the operating member and the second operating force transmitting member in conjunction with the movement of the switching member from the non-operating position to the operating position. Has been.

  In the vehicle seat according to the fourth aspect, the adjusted mechanism is the first to third adjusted mechanisms. Moreover, the switching member is provided in the operation member, and when the switching member is operated, the switching member is moved from the non-operation position to the operation position with respect to the operation member. Furthermore, the operating force transmission mechanism includes a first operating force transmission member, a second operating force transmission member, and a connecting member.

  Here, when the switching member is disposed at the non-operation position, the operating member and the first operating force transmission member are connected by the connecting member. When the operating member rotates to one side in the rotational direction, the connecting member and the first operating force transmission member rotate to one side in the rotational direction, whereby the operating force is transmitted to the first adjusted mechanism. On the other hand, when the operating member rotates to the other side in the rotational direction, the connecting member and the first operating force transmission member rotate to the other side in the rotational direction, whereby the operating force is transmitted to the second adjusted mechanism. Accordingly, the first adjusted mechanism and the second adjusted mechanism can be adjusted or adjusted.

  Further, when the switching member is moved from the non-operation position to the operation position, the connection member connects the operation member and the second operation force transmission member in conjunction with the movement. In this state, when the operating member rotates to one side in the rotational direction or the other side in the rotational direction, the connecting member and the second operating force transmission member are rotated, and the operating force is transmitted to the third adjusted mechanism.

  As described above, the first to third adjustable mechanisms can be adjusted with one operation lever using the operation direction as the rotation direction.

  According to the vehicle seat of the first aspect, it is possible to suppress the concentration of the load when a load other than the rotation direction is applied to the operation member.

  According to the vehicle seat of the second aspect, it is possible to effectively suppress the concentration of loads when a load other than the rotation direction is applied to the operation member.

  According to the vehicle seat of the third aspect, the load transmitting member can receive the load stably.

  According to the vehicle seat of the fourth aspect, the first to third adjustable mechanisms can be adjusted with the operation direction as the rotation direction by one operation lever.

  Hereinafter, with reference to FIGS. 1-9, the vehicle seat 10 which concerns on embodiment of this invention is demonstrated. Note that an arrow FR appropriately shown in each drawing indicates the front of the vehicle, an arrow UP indicates the upper side of the vehicle, and an arrow IN indicates the inner side in the vehicle width direction. Further, in the present embodiment, the front direction, the upper direction, and the width direction of the vehicle seat 10 coincide with the front direction, the upper direction, and the width direction of the vehicle.

  <Configuration of Embodiment>

  As shown in FIGS. 1 and 2, the vehicle seat 10 according to the present embodiment includes a seat body 12 and a seat adjustment device 14. The seat body 12 includes a seat cushion frame 16 constituting a skeleton of the seat cushion and a seat back frame 18 constituting a skeleton of the seat back. A seat pad (not shown) is attached to each of the seat cushion frame 16 and the seat back frame 18 and the surface of each seat pad is covered with a seat skin (not shown).

  The rear end portion of the seat cushion frame 16 and the lower end portion of the seat back frame 18 are connected via a reclining mechanism 20 (first adjusted mechanism) as an angle adjusting mechanism. The reclining mechanism 20 is well known in the art, and is unlocked when the lock release lever 22 is rotated in the lock release direction (the direction of arrow A in FIG. 1), so that the seat back frame 18 moves relative to the seat cushion frame 16. The relative angle (reclining angle) can be adjusted in multiple stages.

  Further, a return spring 24 that urges the seat back frame 18 in a forward tilt direction is stretched between the seat cushion frame 16 and the seat back frame 18. Therefore, when no load is applied to the seat back frame 18 in the unlocked state of the reclining mechanism 20, the seat back frame 18 tilts forward to a predetermined position with respect to the seat cushion frame 16. On the other hand, when a backward load of a predetermined value or more is applied to the seat back frame 18 in the unlocked state of the reclining mechanism 20, the seat back frame 18 tilts backward with respect to the seat cushion frame 16. When the operation force of the lock release lever 22 is released at an arbitrary inclination angle, the reclining mechanism 20 returns to the locked state, and the seat back frame 18 is restrained from being tilted.

  The seat cushion frame 16 is connected to the lower frame 28 via a lifter mechanism 26 (third adjusted mechanism) as a height adjusting mechanism. The lifter mechanism 26 is a well-known one and includes a front link 30 and a rear link 32 (not shown except for FIG. 1) that are rotatably connected to the seat cushion frame 16 and the lower frame 28. . The front link 30 and the rear link 32 form a four-bar link together with the seat cushion frame 16 and the lower frame 28.

  The lifter mechanism 26 includes a conventionally known pump type lifter device 34 (see FIGS. 3, 5, and 6). The pump type lifter device 34 is attached to the outer side surface of the seat cushion frame 16 in the vehicle width direction, and as shown in FIGS. 5 and 6, includes an input shaft 36 whose axial direction is along the seat width direction. ing. When the input shaft 36 is rotated, the rotational force of the input shaft 36 is transmitted to the rear link 32 via the pinion 33 and the lifter gear 35 (see FIGS. 5 and 6) attached to the seat cushion frame 16. It is like that. Thereby, the rear link 32 and the front link 30 are rotated, and the arrangement height of the seat cushion frame 16 with respect to the lower frame 28 is adjusted. In this case, when the input shaft 36 is rotated to one side in the rotational direction (the direction of arrow B in FIGS. 3 and 4), the seat cushion frame 16 is displaced upward, and the input shaft 36 is moved to the other side in the rotational direction (see FIGS. 3 and 4). When rotated in the direction of arrow C in FIG. 4, the seat cushion frame 16 is displaced downward.

  As shown in FIGS. 1 and 2, below the lower frame 28, a slide rail 40 that is a constituent member of a slide mechanism 38 (second adjusted mechanism) as a front-rear position adjustment mechanism is disposed. The slide mechanism 38 is well known in the art, and an upper rail 42 fixed to the lower end portion of the lower frame 28 is supported by a lower rail 44 fixed to the vehicle body floor so as to be slidable in the front-rear direction of the seat. The slide mechanism 38 is provided with a lock mechanism (not shown) that locks (regulates) the slide of the upper rail 42 with respect to the lower rail 44. The lock mechanism is configured to release the lock when the lock release lever 46 pivotally supported by the lower frame 28 is rotated in the lock release direction (the direction of arrow D in FIG. 1). As a result, the upper rail 42 slides with respect to the lower rail 44, that is, the front and rear position of the vehicle seat 10 with respect to the vehicle body floor can be adjusted.

  Next, the sheet adjustment device 14 will be described.

  As shown in FIGS. 3 to 6, the seat adjustment device 14 includes a meshing clutch mechanism 48 as an operation force transmission mechanism. The mesh clutch mechanism 48 is disposed on the outer side in the seat width direction of the pump type lifter device 34 described above, and has a plate 50. The plate 50 is formed in a disk shape from a metal material, and is disposed coaxially with the input shaft 36 of the pump lifter device 34. A concave fitting portion (not shown) is formed on the surface of the central portion of the plate 50 on the pump lifter device 34 side, and the fitting portion is connected to the input shaft 36 of the pump lifter device 34. The provided convex fitting part 52 is fitted. The fitting portion and the fitting portion 52 are formed in a three-pronged shape when viewed from the sheet width direction, and thereby the relative rotation of the plate 50 with respect to the input shaft 36 is restricted.

  An inner clutch member 54 as a second operating force transmission member, which is a component member of the mesh clutch mechanism 48, is disposed on the opposite side of the pump lifter mechanism 26 via the plate 50. The inner clutch member 54 is formed in a disk shape from a resin material, and is disposed coaxially with the input shaft 36 of the pump lifter device 34. A plurality of (here, three) convex portions 56 projecting toward the plate 50 are provided on the surface of the inner clutch member 54 on the side of the plate 50. These convex portions 56 are arranged at equal intervals in the circumferential direction of the inner clutch member 54, and are fitted into a plurality of (here, three) cutout portions 59 formed on the outer peripheral portion of the plate 50. Yes. Accordingly, the relative rotation of the inner clutch member 54 with respect to the plate 50 is restricted, and the inner clutch member 54 is coupled to the input shaft 36 via the plate 50 so as to be integrally rotatable. In addition, clutch teeth 58 are formed on the surface of the outer peripheral portion of the inner clutch member 54 opposite to the plate 50. The clutch teeth 58 are constituted by a plurality of teeth arranged at equal intervals in the circumferential direction of the inner clutch member 54, and are provided over the entire circumference of the outer peripheral portion of the inner clutch member 54.

  A case 60 that is a constituent member of the mesh clutch mechanism 48 is disposed on the opposite side of the plate 50 via the inner plate 50. The case 60 is formed in a bottomed cylindrical shape opened inward in the sheet width direction by a resin material, and the bottom wall 62 of the case 60 is disposed along a direction orthogonal to the sheet width direction. The side wall 63 of 60 is extended | stretched by the same diameter along the sheet | seat width direction. The case 60 is disposed coaxially with the pump lifter device 34. As shown in FIGS. 5 and 6, a support portion 64 protruding toward the inner clutch member 54 is integrally and coaxially provided at the center portion of the bottom wall 62 of the case 60. The support portion 64 is formed in a bottomed cylindrical shape having an opening on the outer side in the sheet width direction, and a circular through hole 64A is formed in the bottom wall portion. A cylindrical collar 66 is coaxially inserted into the through hole 64A.

  One end of the collar 66 in the axial direction (inner side in the sheet width direction) is inserted into a circular through hole formed in the central portion of the inner clutch member 54 and a circular through hole formed in the central portion of the plate 50. The one end portion in the axial direction of the collar 66 is in contact with the one end surface in the axial direction of the input shaft 36 (the end portion on the outer side in the sheet width direction). Bolts 68 are inserted into the collar 66 from the outside in the sheet width direction, and the front end side of the bolts 68 is screwed into a female thread portion formed on the input shaft 36. As a result, the collar 66 is fastened and fixed to the input shaft 36, and the movement of the support portion 64 (that is, the case 60) with respect to the input shaft 36 to the outside in the seat width direction is restricted by the head of the bolt 68. Further, the center side of the inner clutch member 54 and the center side of the plate 50 are sandwiched between the bottom wall of the support portion 64 and the input shaft 36. Thereby, the axial movement of the plate 50 and the inner clutch member 54 with respect to the input shaft 36 is restricted, and the movement of the case 60 with respect to the input shaft 36 in the seat width direction is restricted. However, the length of the collar 66 is set so that the relative rotation of the case 60 with respect to the input shaft 36 is not restricted by the bolt 68, and the case 60 is rotatable relative to the input shaft 36. As a result, the case 60 (meshing clutch mechanism 48) is rotatably provided on the seat cushion frame 16 (seat body 12) via the input shaft 36, and rotates around one axis of the input shaft 36 (see FIG. 3 and the arrow B direction shown in FIG. 4 and the rotation direction other side (arrow C direction shown in FIG. 3 and FIG. 4).

  A plurality (three in this case) of cylindrical portions 70 projecting outward in the sheet width direction are provided on the outer surface of the bottom wall 62 of the case 60 in the sheet width direction. The cylindrical portions 70 are formed in a cylindrical shape and are arranged at equal intervals in the circumferential direction of the case 60. One side of the bottom wall 62 of the case 60 is disposed inside the cylindrical portions 70. The inside (sheet width direction inner side) and the other side (sheet width direction outer side) communicate. These cylindrical portions 70 correspond to a plurality of rod-like portions 80 provided on the moving clutch member 72 described later. A metal nut (not shown) is embedded between the plurality of cylindrical portions 70 in the bottom wall 62 of the case 60 by insert molding. These nuts correspond to an operation lever 118 described later.

  Inside the case 60 described above, a moving clutch member 72 as a connecting member, which is a constituent member of the mesh clutch mechanism 48, is accommodated. The moving clutch member 72 is formed in a cylindrical shape having a short axial dimension by a resin material, and the support portion 64 of the case 60 is inserted inside. An outer peripheral side spline portion 74 (see FIG. 5) and an inner peripheral side spline portion 76 (see FIGS. 3 and 4) that engage with each other are formed on the outer peripheral surface of the support portion 64 and the inner peripheral surface of the moving clutch member 72, respectively. Has been. That is, the outer peripheral side spline portion 74 having an uneven cross section formed along the axial direction on the outer peripheral surface of the support portion 64 and the inner surface having an uneven cross section formed along the axial direction on the inner peripheral surface of the moving clutch member 72. When the circumferential spline portion 76 is slidably engaged, the moving clutch member 72 is attached to the case 60 so as to be integrally rotatable and movable in the axial direction.

  The moving clutch member 72 is formed with an annular groove that opens inward in the seat width direction, and a metal compression coil spring 78 that is a component of the mesh clutch mechanism 48 is accommodated in the annular groove. ing. The compression coil spring 78 is disposed coaxially with the moving clutch member 72, and has one axial end contacting the inner clutch member 54 and the other axial end contacting the bottom surface of the annular groove. . Accordingly, the moving clutch member 72 is urged toward the outer side in the sheet width direction, and is normally held in a state where the end surface on the outer side in the sheet width direction is in contact with the bottom wall 62 of the case 60.

  The above-described moving clutch member 72 has a large-diameter portion on one end side in the axial direction (inner side in the sheet width direction) and a small-diameter portion on the other end side in the axial direction (outer side in the sheet width direction). A plurality (three in this case) of rod-shaped portions 80 projecting outward in the sheet width direction are provided on the end surface of the small diameter portion on the outer side in the sheet width direction. These rod-shaped portions 80 are formed in a columnar shape, and are arranged at equal intervals in the circumferential direction of the moving clutch member 72 in a state where the axial direction is along the seat width direction. These rod-shaped portions 80 are inserted into the plurality of tubular portions 70 provided on the bottom wall 62 of the case 60 described above, and the leading end side protrudes outward in the sheet width direction from the tubular portion 70. These rod-shaped portions 80 correspond to a switching member 136 described later.

  Clutch teeth 82 are formed on the inner surface of the moving clutch member 72 on the inner side in the sheet width direction over the entire circumference of the moving clutch member 72. The clutch teeth 82 are constituted by a plurality of teeth arranged at equal intervals in the circumferential direction of the moving clutch member 72 and can mesh with the clutch teeth 58 of the inner clutch member 54. In a state where the clutch teeth 58 and the clutch teeth 82 are engaged with each other, the inner clutch member 54 and the moving clutch member 72 are coupled so as to be integrally rotatable. However, normally, the moving clutch member 72 is held at a position away from the inner clutch member 54 by the urging force of the compression coil spring 78, and the engagement between the clutch teeth 58 and the clutch teeth 82 is released.

  Clutch teeth 84 are formed on the outer surface of the moving clutch member 72 on the outer side in the sheet width direction over the entire circumference of the moving clutch member 72. The clutch teeth 84 are constituted by a plurality of teeth arranged at equal intervals in the circumferential direction of the moving clutch member 72, and correspond to an outer clutch member 86 as a first operating force transmission member described later.

  The outer clutch member 86 is a component member of the meshing clutch mechanism 48 and includes a main body portion 88 formed in a ring shape. A pair of convex portions projecting radially outward are provided on the outer peripheral portion of the main body portion 88, and these convex portions are fitted into concave grooves formed on the inner peripheral surface of the side wall 63 of the case 60. . Thus, the main body 88 is connected to the case 60 so as not to move in the axial direction and to be rotatable relative to a predetermined range. The small diameter portion of the moving clutch member 72 is rotatably inserted inside the main body portion 88, and the outer clutch member 86 is rotatable relative to the moving clutch member 72. Clutch teeth 90 are formed on one end surface in the axial direction of the main body portion 88 (end surface on the inner side in the sheet width direction) over the entire periphery of the main body portion 88. The clutch teeth 90 are constituted by a plurality of teeth arranged at equal intervals in the circumferential direction of the main body portion 88, and can engage with the clutch teeth 84 of the moving clutch member 72. The clutch teeth 90 are normally engaged with the clutch teeth 84 because the moving clutch member 72 is urged outward in the seat width direction by the urging force of the compression coil spring 78. Thus, in a state where the clutch teeth 84 and the clutch gear 90 mesh with each other, the moving clutch member 72 and the outer clutch member 86 are coupled so as to be integrally rotatable.

  However, when the moving clutch member 72 is displaced inward in the seat width direction against the biasing force of the compression coil spring 78, the engagement between the clutch teeth 90 of the outer clutch member 86 and the clutch teeth 84 of the moving clutch member 72 is released. In addition, the clutch teeth 82 of the moving clutch member 72 and the clutch teeth 58 of the inner clutch member 54 are engaged with each other. In this state, as described above, the moving clutch member 72 and the inner clutch member 54 are coupled so as to be integrally rotatable.

  Further, as shown in FIGS. 3 and 4, the outer clutch member 86 is provided with a connecting portion 92 that protrudes outward in the radial direction of the main body portion 88. The connecting portion 92 projects to the outside of the case 60 through a notch formed in a part of the side wall 63 of the case 60, and extends obliquely downward to the rear of the seat. The connecting portion 92 corresponds to the link member 94 and the wire 96.

  One end of the wire 96 is locked to the lock release lever 46 of the slide mechanism 38 described above, and the other end is locked to the connecting portion 92. For this reason, when the outer clutch member 86 rotates in the direction in which the connecting portion 92 is displaced rearward of the seat (the direction of arrow C in FIGS. 3 and 4), the rotational force of the outer clutch member 86 is unlocked via the wire 96. 46, and the lock release lever 46 is rotated in the lock release direction. Thereby, the lock | rock of the slide mechanism 38 is cancelled | released.

  On the other hand, the link member 94 is formed in a long shape with a sheet metal material. As shown in FIGS. 1 and 2, one end of the link member 94 in the longitudinal direction is connected to the tip of the lock release lever 22 of the reclining mechanism 20 via a connecting shaft 95 along the seat width direction. And are rotatably connected. On the other end side in the longitudinal direction of the link member 94, a bead portion 98 that opens to the outside in the sheet width direction is formed. The bead portion 98 extends along the longitudinal direction of the link member 94. The bead portion 98 corresponds to the convex portion 100 (see FIG. 4) provided in the connecting portion 92.

  The convex part 100 protrudes inward in the sheet width direction from the front end part (lower end part) of the connecting part 92 and is inserted inside the bead part 98. Further, an L-shaped arm portion 102 extends from the base end side of the connecting portion 92, and the arm portion 102 is in contact with the inner surface of the link member 94 in the sheet width direction. Thereby, the connection part 92 is connected with the link member 94 so that relative movement within the range along the bead part 98 is possible. Further, a contact piece 104 extending outward in the seat width direction is provided at the other longitudinal end of the link member 94, and the contact piece 104 faces the connecting portion 92 from the front side of the seat. Yes.

  For this reason, when the outer clutch member 86 rotates in one direction of rotation (the direction of arrow B in FIGS. 3 and 4), the connecting portion 92 is displaced to the front side of the seat and contacts the contact piece 104. As a result, the link member 94 is pulled toward the front side of the seat. Thereby, the rotational force of the outer clutch member 86 is transmitted to the lock release lever 22 via the link member 94, and the lock release lever 22 is rotated in the lock release direction. As a result, the reclining mechanism 20 is unlocked. In this case, the wire 96 bends between the connecting portion 92 and the lock release lever 46 so that the rotational force of the outer clutch member 86 is not transmitted to the lock release lever 46.

  On the other hand, when the outer clutch member 86 rotates in the other direction of rotation (the direction of arrow C in FIGS. 3 and 4), the connecting portion 92 is displaced to the rear side of the seat, and as described above, the outer clutch member 86. Is transmitted to the lock release lever 22 of the slide mechanism 38 via the wire 96. In this case, when the convex portion 100 moves to the rear end side (upper end side) of the bead portion 98, the connecting portion 92 moves relative to the link member 94 to the rear side of the seat. As a result, the rotational force of the outer clutch member 86 is not transmitted to the lock release lever 22 of the reclining mechanism 20 via the link member 94.

  The mesh clutch mechanism 48 described above is covered with a cover 106 as a load transmission member. The cover 106 includes a cylindrical portion 107 and a pair of flange portions 108 as fixed portions.

  The cylindrical portion 107 is formed in a substantially bottomed cylindrical shape that opens to the inside in the sheet width direction, and is disposed coaxially with the pump lifter device 34. The side wall 110 of the cylindrical portion 107 extends in the sheet width direction with the same diameter from the bottom wall 114 of the cylindrical portion 107 to the intermediate portion in the sheet width direction, and increases in diameter toward the inner side in the sheet width direction from the intermediate portion in the sheet width direction. Has been stretched. That is, the width of the outer shape of the side wall 110 is set wider on the side of the seat cushion frame 16 than on the bottom wall 114. A meshing clutch mechanism 48 is disposed inside the cylinder portion 107. Thereby, the side wall 110 of the cylinder part 107 and the side wall 63 of the case 60 are arranged in parallel, and the bottom wall 114 of the cylinder part 107 and the bottom wall 62 of the case 60 are arranged in parallel. A slight gap is provided between the side wall 110 and the bottom wall 114 and the outer peripheral portion of the case 60.

  The pair of flange portions 108 extend from the seat front side portion and the sheet rear side portion of the opening portion of the cylinder portion 107 to the outside in the radial direction of the cylinder portion 107 and along a direction orthogonal to the sheet width direction. Has been placed. The flange portion 108 is fastened and fixed to the side surface of the seat cushion frame 16 on the outer side in the vehicle width direction by a plurality of bolts and nuts (not shown). In addition, a plurality of reinforcing ribs 112 are spanned between the side wall 110 and the flange portion 108 of the cylindrical portion 107, and thereby the cover 106 is reinforced against the radial load of the cylindrical portion 107. ing.

  Further, a circular through hole is coaxially formed at the center of the bottom wall 114 of the cover 106, and the bottom wall 62 of the case 60 is exposed to the outside in the sheet width direction of the cover 106 through the through hole. doing. A pair of front and rear restricting protrusions 116 is provided on the outer surface of the bottom wall 114 of the cover 106 in the seat width direction. These restricting protrusions 116 are arranged on the opposite sides through the through holes of the bottom wall 114, and protrude toward the outside in the sheet width direction. These restricting protrusions 116 correspond to a switching member 136 described later.

  An operation lever 118 as an operation member is disposed outside the cover 106 in the sheet width direction. The operation lever 118 constitutes the sheet adjustment device 14 and includes a lever main body 120 and a lid portion 122. The lever body 120 is formed in a long shape by a resin material, and has a substantially bottomed cylindrical base portion 124 having an axial dimension that is open on the outer side in the seat width direction, and an outer peripheral portion of the base portion 124 toward the seat front side. The arm portion 126 extends. The arm portion 126 is formed in a substantially U-shaped cross section that is open on the outer side in the sheet width direction. On the other hand, the lid 122 is formed in a long plate shape with a resin material and is mounted on the opening side (outer side in the sheet width direction) of the lever main body 120 to close the opening of the lever main body 120.

  In this operation lever 118, a plurality (three here) screws (not shown) penetrating the bottom wall 128 of the base portion 124 are screwed into nuts (not shown) embedded in the bottom wall 62 of the case 60 of the mesh clutch mechanism 48. By doing so, the case 60 is fastened and fixed. In addition, a plurality of convex portions provided on the bottom wall 62 of the case 60 are fitted in concave portions formed on the bottom wall 128 of the base portion 124. For this reason, the operation lever 118 rotates around the axis of the input shaft 36 integrally with the case 60. Further, the bottom wall 128 of the base portion 124 is formed with through holes for inserting the plurality of cylindrical portions 70 of the case 60 described above, and the tips of the plurality of rod-shaped portions 80 penetrating the respective cylindrical portions 70. The side projects into the operation lever 118 (in the base 124). Further, a pair of front and rear arc holes 130 are formed in the bottom wall 128 of the base portion 124. These arc holes 130 are formed in an arc shape centered on the rotation center of the operation lever 118. The pair of restricting protrusions 116 of the cover 106 described above are inserted through these arc holes 130, and the distal end side of each restricting protrusion 116 protrudes into the operation lever 118 (inside the base portion 124).

  A torsion coil spring 132 as an urging member is disposed between the operation lever 118 and the cover 106 described above. As shown in FIGS. 5 and 6, the torsion coil spring 132 is accommodated in an annular groove formed in the bottom wall 128 of the base portion 124, and one end side locking portion formed at one end portion in the torsion direction. The other end side locking portion formed at the other end in the twisting direction is locked to the locking portion 134 provided on the bottom wall 114 of the cover 106. Thereby, the operation lever 118 is normally held at the neutral position shown in FIGS. 1 and 2 by the biasing force of the torsion coil spring 132, and when the arm portion 126 is lifted above the neutral position, and The torsion coil spring 132 is elastically deformed when pushed down from the neutral position. For this reason, when the lifting force or the pushing-down force no longer acts on the arm portion 126, the operation lever 118 returns to the neutral position by the urging force of the torsion coil spring 132.

  A switching member 136 is housed inside the operation lever 118. The switching member 136 is formed in a long shape with a resin material, and is disposed along the longitudinal direction of the operation lever 118. The switching member 136 is engaged with a plurality of support portions (not shown) provided on the lever main body 120 and the cover 106, and is supported so as to be slidable in the longitudinal direction with respect to the operation lever 118. The switching member 136 has a rod-shaped rod portion 138 at one end in the longitudinal direction and a plate-like plate portion 140 at the other end in the longitudinal direction. A long rectangular shape is provided between the rod portion 138 and the plate portion 140. A frame-shaped spring accommodating portion 142 is provided. Furthermore, a columnar operation button portion 146 is provided at the tip end portion of the rod portion 138 (the end portion on the front side of the seat: the end portion on the side opposite to the spring accommodating portion 142). The operation button portion 146 is inserted through a circular opening formed at the tip end portion (the end portion on the front side of the seat) of the arm portion 126 and protrudes from the arm portion 126 toward the front side of the seat.

  The rod portion 138 extends along the arm portion 126, and a spring accommodating portion 142 is disposed near the base end portion of the arm portion 126. A compression coil spring 148 is provided in the spring accommodating portion 142. The compression coil spring 148 is arranged in a state where the axial direction is along the longitudinal direction of the operation lever 118. One end of the compression coil spring 148 in the axial direction is engaged with the spring accommodating portion 142 by fitting a cylindrical positioning portion 149 provided at the end of the rod accommodating portion 138 in the spring accommodating portion 142 to the inside. It has been stopped. The other end in the axial direction of the compression coil spring 148 is pressed against a projecting piece 151 that extends from the bottom wall of the arm portion 126 and is inserted into the spring accommodating portion 142. Thereby, the switching member 136 is urged toward the front end side of the operation lever 118. For this reason, the switching member 136 is normally held in the non-operation position shown in FIGS. 1, 2, 7 and 8, and the operation button portion 146 is pushed toward the operation lever 118 side, so that FIG. It is configured to be moved to the operation position shown in FIG. When the pushing force acting on the operation button unit 146 is released, the switching member 136 is returned to the non-operation position by the urging force of the compression coil spring 148.

  On the other hand, the plate portion 140 of the switching member 136 is accommodated in the base portion 124 in a state where the plate thickness direction is along the sheet width direction. As shown in FIGS. 5 and 6, a plurality of inclined protrusions 150 are provided on the inner surface of the plate portion 140 in the sheet width direction. These inclined projections 150 are arranged at positions facing the tip portions of the plurality of rod-like portions 80 of the moving clutch member 72 described above. The inclined protrusions 150 have flat end surfaces 150A at the ends of the plurality of rod-shaped portions 80 (inner side in the sheet width direction), and inclined side surfaces 150B. The inclined surface 150B is continuous with the flat surface 150A, and is inclined so as to go outward in the seat width direction toward the rear side of the seat.

  As shown in FIG. 5, in a state where the switching member 136 is located at the non-operation position, the plurality of inclined protrusions 150 are disposed at positions shifted forward of the seat with respect to the plurality of rod-shaped portions 80. In this state, the moving clutch member 72 is held at a position away from the inner clutch member 54 by the urging force of the compression coil spring 78, and the clutch teeth 84 of the moving clutch member 72 and the clutch teeth 90 of the outer clutch member 86 are connected. I'm engaged.

  On the other hand, as shown in FIG. 6, when the switching member 136 is slid to the operating position, the tips of the plurality of rod-shaped portions 80 are pushed inward in the sheet width direction by the inclined surfaces 150 </ b> B of the plurality of inclined protrusions 150. By riding on the surface 150 </ b> A, the moving clutch member 72 is moved inward in the seat width direction against the urging force of the compression coil spring 78. Thus, the clutch teeth 84 of the moving clutch member 72 and the clutch teeth 90 of the outer clutch member 86 are released, while the clutch teeth 82 of the moving clutch member 72 and the clutch teeth 58 of the inner clutch member 54 are engaged. It is like that.

  In addition, a pair of upper and lower restricting pieces 152 are provided at the front end portion and the rear end portion of the plate portion 140 described above. These restricting pieces 152 protrude inward in the sheet width direction and correspond to the pair of front and rear restricting protrusions 116 described above. That is, when the switching member 136 is moved between the non-operating position and the operating position, the pair of upper and lower restricting pieces 152 pass above and below the restricting protrusion 116. For this reason, in a state where the switching member 136 is located between the non-operation position and the operation position, the pair of upper and lower restricting pieces 152 engages (impacts) with the restricting protrusions 116, so that the operation lever 118 from the neutral position is moved. Rotation is restricted. In a state where the operation lever 118 is operated to the upper side or the lower side of the neutral position (including a state in the middle of operation), one of the pair of upper and lower restricting pieces 152 abuts against the restricting protrusion 116, thereby The movement of the switching member 136 from the operation position to the operation position or the movement of the switching member 136 from the operation position to the non-operation position is restricted.

  Here, when a load (for example, a load in the sheet width direction) other than one side in the rotation direction or the other side in the rotation direction is applied to the arm portion 126 of the operation lever 118, the vertical direction is used as the axis of the operation lever 118. The rotational moment in the direction of arrow E or arrow F shown in FIGS. 5 and 6 acts. Therefore, the operation lever 118 and the case 60 (meshing clutch mechanism 48) swing (move) in the direction of the arrow G or the arrow H shown in FIG. When the amount of movement exceeds a reference value, the bottom wall 62 and the side wall 63 of the case 60 are configured to come into contact with the bottom wall 114 and the side wall 110 of the cover 106, respectively.

  <Operation and Effect of Embodiment>

  Next, the operation and effect of this embodiment will be described.

  In the vehicle seat 10 configured as described above, the operation lever 118 is rotatably attached to the seat cushion frame 16. The operation lever 118 can be operated by an occupant seated on the seat body 12 by gripping the arm portion 126 and moving upward (one side in the rotational direction) or below (the other side in the rotational direction). Further, a switching member 136 having an operation button part 146 protruding from the tip of the arm part 126 is attached to the operation lever 118, and an occupant holding the arm part 126 presses the operation button part 146 with a thumb or the like. Thus, the switching member 136 is moved from the non-operation position to the operation position.

  When the switching member 136 is in the non-operating position (non-operating state), the clutch teeth 84 of the moving clutch member 72 and the clutch teeth 90 of the outer clutch member 86 are engaged with each other, whereby the moving clutch member 72 and the outer clutch member 86 are engaged. And are connected so as to be integrally rotatable. In this non-operating state, when the arm portion 126 of the operating lever 118 is operated to the upper side of the neutral position (one side in the rotational direction) as shown by a two-dot chain line in FIG. 7, the operating force is transmitted to the case 60. Then, the case 60, the moving clutch member 72, and the outer clutch member 86 are rotated in the direction of arrow B in FIGS. This operating force (rotational force) is transmitted to the lock release lever 22 of the reclining mechanism 20 via the link member 94, and the lock release lever 22 is rotated in the lock release direction. As a result, the reclining mechanism 20 is unlocked and the reclining angle of the seat back can be adjusted.

  Further, in the non-operating state, when the arm portion 126 of the operating lever 118 is operated to the lower side (the other side in the rotational direction) of the neutral position as shown by a two-dot chain line in FIG. 60, the case 60, the moving clutch member 72, and the outer clutch member 86 are rotated in the direction of arrow C in FIGS. This operating force (rotational force) is transmitted to the lock release lever 46 of the slide mechanism 38 via the wire 96, and the lock release lever 46 is rotated in the lock release direction. Thereby, the lock | rock of the slide mechanism 38 is cancelled | released and it will be in the state which can adjust the front-back position of the vehicle seat 10. FIG.

  On the other hand, in a state where the switching member 136 is moved to the operation position (operation state) by the occupant pressing the operation button unit 146, the plurality of rod-shaped portions 80 of the moving clutch member 72 are connected to the plurality of switching members 136. By being pushed by the inclined protrusion 150, the moving clutch member 72 moves inward in the sheet width direction. As a result, the engagement of the clutch teeth 84 of the moving clutch member 72 and the clutch teeth 90 of the outer clutch member 86 is released, and the clutch teeth 82 of the moving clutch member 72 and the clutch teeth 58 of the inner clutch member 54 are engaged. . Thereby, the movement clutch member 72 and the inner side clutch member 54 are connected so that integral rotation is possible. In this operation state, when the arm portion 126 of the operation lever 118 is operated to the upper side of the neutral position (one side in the rotational direction) as shown by a two-dot chain line in FIG. It is transmitted to the input shaft 36 of the pump type lifter device 34 (lifter mechanism 26) via the member 72, the inner clutch member 54 and the plate 50. As a result, the input shaft 36 is rotated in the direction of arrow B in FIGS. 3 and 4, and the rotational force of the input shaft 36 is transmitted to the rear link 32 via the pinion 33 and the lifter gear 35. It is displaced upward with respect to the lower frame 28 (the seat height is adjusted high). In FIG. 9, the illustration of the state in which the seat cushion frame 16 is displaced with respect to the lower frame 28 is omitted.

  Further, in the above operation state, when the arm portion 126 of the operation lever 118 is operated to the lower side (the other side in the rotation direction) of the neutral position as shown by a one-dot chain line in FIG. This is transmitted to the input shaft 36 of the pump lifter device 34 via the moving clutch member 72, the inner clutch member 54 and the plate 50. As a result, the input shaft 36 is rotated in the direction of arrow C in FIGS. 3 and 4, and the rotational force of the input shaft 36 is transmitted to the rear link 32 via the pinion 33 and the lifter gear 35. Is displaced downward with respect to the lower frame 28 (the seat height is adjusted low).

  As described above, in the vehicle seat 10, the reclining mechanism 20, the slide mechanism 38, and the lifter mechanism 26 can be adjusted or made adjustable by a single operation lever 118. In addition, since the operation direction of the arm portion 126 of the operation lever 118 is only the upper side and the lower side and is simple, the operability can be improved and the space can be effectively used. In particular, it is preferable in that it can be applied to a small vehicle or the like in which it is difficult to secure a wide space between the vehicle seat and the vehicle body side portion (side door or the like).

  Incidentally, the case 60 is rotatably supported by a bolt 68 (collar 66) at the portion of the through hole 64A, and the operation lever 118 is fixed to the case 60 so as to be integrally rotatable. Therefore, when a load (for example, a load in the sheet width direction) other than one side in the rotational direction or the other side in the rotational direction is applied to the arm portion 126 of the operation lever 118, the operation lever 118 is vertically moved (input shaft 36). A rotational moment acting in the direction of arrow E or arrow F shown in FIGS. For this reason, the operation lever 118 and the case 60 (meshing clutch mechanism 48) swing (move) in the arrow G direction or the arrow H direction shown in FIG.

  Here, the cover 106 is fastened and fixed to the cushion frame 16. When a load other than the rotation direction is applied to the operation lever 118 and the amount of swing (movement) of the case 60 (meshing clutch mechanism 48) exceeds a reference value, the bottom wall 62 of the case 60 is covered. The side wall 63 of the case 60 abuts against the side wall 110 of the cylinder portion 107. For this reason, the load applied (input) to the case 60 (meshing clutch mechanism 48) is dispersed in the cover 106 and transmitted to the cushion frame 16. Thereby, it can suppress that this load concentrates on the site | part of the through-hole 64A of case 60. FIG.

  In addition, in this case, the case 60 (meshing clutch mechanism 48) is held by the cover 106 by the case 60 coming into contact with the cylindrical portion 107. For this reason, the swing (movement) of the case 60 (meshing clutch mechanism 48) exceeding the reference value can be suppressed, and consequently the swing (movement) of the operation lever 118 can be suppressed. Thereby, it can also be suppressed that an excessive load is applied (input) from the operation lever 118 to the case 60 (meshing clutch mechanism 48).

  Further, when the case 60 swings around the axis orthogonal to the input shaft 36 at the portion of the through hole 64A and the bottom wall 62 of the case 60 comes into contact with the bottom wall 114 of the cylindrical portion 107, the case 60 A radially outer portion of the bottom wall 62 is in contact with the bottom wall 114 of the cylindrical portion 107. For this reason, a load in a direction intersecting the axis of the input shaft 36 (see the arrow G direction and the arrow H direction in FIG. 5) acts on the bottom wall 114 of the cylindrical portion 107 from the case 60. And the side wall 110 of the cylinder part 107 of the cover 106 is extended | stretched so that it may expand in diameter as it goes to a sheet | seat width direction inner side from a sheet | seat width direction intermediate part. As a result, the direction of the load acting on the bottom wall 114 of the cylinder part 107 and the extending direction of the side wall 110 are substantially coincided with each other, so that the cylinder part 107 receives the load along the extending direction of the side wall 110. it can. Moreover, the cylindrical portion 107 can receive the load as a tensile load. Therefore, since the cover 106 can transmit a load to the cushion frame 16 while suppressing the deformation of the cylindrical portion 107, it is possible to effectively suppress the load from being concentrated on the portion of the through hole 64A of the case 60.

  Further, the cover 106 is fastened and fixed to the cushion frame 16 at the flange portion 108, and the flange portion 108 is provided on the radially outer side of the cylindrical portion 107. For this reason, since the cover 106 can be fixed on the radially outer side of the cylindrical portion 107 to which a load from the case 60 (meshing clutch mechanism 48) acts, the cover 106 can stably receive the load.

  Further, a reinforcing rib 112 is integrally bridged between the side wall 110 of the cylindrical portion 107 of the cover 106 and the flange portion 108. Thereby, the load acting on the side wall 110 of the cylindrical portion 107 from the side wall 63 of the case 60 can also be received by the reinforcing rib 112. For this reason, the load can be transmitted to the seat cushion frame 16 while suppressing the deformation of the cylindrical portion 107 with respect to the load.

  Further, the cylindrical portion 107 of the cover 106 is formed in a substantially bottomed cylindrical shape, and the cylindrical portion 107 covers substantially the entire outer peripheral portion of the case 60. Thereby, for example, it is possible to suppress the grease applied to the moving clutch member 72 and the like from being scattered outside the cover 106.

  In addition, a regulation projection 116 is provided on the bottom wall 114 of the cylindrical portion 107 of the cover 106. For this reason, the rotation of the switching member 136 can be restricted using the cover 106 that transmits the load from the case 60 to the seat cushion frame 16. That is, the cover 106 can be provided with a load transmission function and a rotation restriction function of the switching member 136.

  In the present embodiment, when a load other than the rotation direction is applied to the operation lever 118 and the amount of swing (movement) of the case 60 (meshing clutch mechanism 48) exceeds a reference value, the case 60 The bottom wall 62 and the side wall 63 are configured to abut against the cylindrical portion 107 of the cover 106. Instead, the bottom wall 62 or the side wall 63 of the case 60 comes into contact with the cylindrical portion 107 of the cover 106 when the amount of swing (movement) of the case 60 (meshing clutch mechanism 48) exceeds a reference value. You may comprise. When the bottom wall 62 of the case 60 is configured to come into contact with the cylindrical portion 107 of the cover 106, the side wall 110 of the cover 106 is formed so as to increase in diameter from the bottom wall 114 toward the inside in the sheet width direction. May be.

  Further, when the swinging (moving) amount of the case 60 (meshing clutch mechanism 48) exceeds a reference value, the base portion 124 of the operation lever 119 is brought into contact with the bottom wall 114 of the cylindrical portion of the cover 106. It may be configured. Thereby, it can suppress further that a load concentrates on the site | part of the through-hole 64A of case 60. FIG.

  Furthermore, although the vehicle seat 10 includes the lifter mechanism 26 in the present embodiment, the lifter mechanism 26 may be omitted. In this case, for example, the case 60 may be configured to directly support the seat cushion frame 16, and the switching member 136 of the operation lever 118 and the inner clutch member 54 of the meshing clutch mechanism 48 may be omitted.
