Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above prior art, since the metal arm (metal lever) and the resin grip portion (resin lever) are fitted to each other, high dimensional accuracy is required for both components. If the dimensional accuracy is low, rattling occurs when operating the grip portion, which is unfavorable in terms of quality.

[0005] The present invention has been made in view of the above facts, and an object thereof is to provide an operation lever and a vehicle seat that enable simple dimensional management to prevent rattling between the metal lever and the resin lever.

Means for Solving the Problems

[0006] The operating lever according to the first embodiment is an operating lever provided on the outer side of the seat body in the width direction of the seat body and capable of operating the seat body, comprising a metal lever which serves as a skeletal member of the operating lever, and a resin lever into which the metal lever is inserted and which is integrated with the metal lever to constitute the design of the operating lever, wherein the metal lever is configured to include an insertion portion which can be inserted into the resin lever, a first convex portion formed in the insertion portion which protrudes upward from the upper end in the width direction of the insertion portion which is substantially perpendicular to the insertion direction of the insertion portion, and a second convex portion formed in the insertion portion which protrudes downward from the lower end in the width direction of the insertion portion, and the The resin lever is composed of an insertable portion into which the insertion portion can be inserted; an upper wall surface formed in the insertable portion along the insertion direction of the insertion portion, to which the first protrusion can abut when the insertion portion is inserted into the insertable portion; a lower wall surface formed in the insertable portion along the insertion direction of the insertion portion, to which the second protrusion can abut when the insertion portion is inserted into the insertable portion; a first hole formed in the inner wall portion that constitutes the inside in the sheet width direction of the insertable portion, connected to the upper wall surface, with a part of the upper wall surface exposed; and a second hole formed in the inner wall portion, connected to the lower wall surface, with a part of the lower wall surface exposed.

[0007] In the first embodiment, the operating lever is provided on the outer side of the seat body in the width direction and is capable of operating the seat body. The operating lever comprises a metal lever and a resin lever, with the metal lever serving as the skeletal member of the operating lever. On the other hand, the resin lever is integrated with the metal lever when the metal lever is inserted into it, forming the design of the operating lever.

[0008] Here, the metal lever is composed of an insertion portion, a first projection, and a second projection, with the insertion portion being inserted into the resin lever. The first projection and the second projection are formed on the insertion portion, respectively. The first projection protrudes upward from the upper end of the insertion portion in the width direction, which is substantially perpendicular to the insertion direction of the insertion portion, and the second projection protrudes downward from the lower end of the insertion portion in the width direction.

[0009] The resin lever is composed of an insertion portion, an upper wall surface, a lower wall surface, a first hole, and a second hole, with the insertion portion into which the insertion portion of the metal lever can be inserted. The upper wall surface is formed in the insertion portion of the resin lever along the insertion direction of the insertion portion of the metal lever. When the insertion portion of the metal lever is inserted into the insertion portion of the resin lever, the first protrusion formed at the upper end of the metal lever can contact the upper wall surface. The lower wall surface is formed in the insertion portion of the resin lever along the insertion direction of the insertion portion of the metal lever. When the insertion portion of the metal lever is inserted into the insertion portion of the resin lever, the second protrusion formed at the lower end of the metal lever can contact the lower wall surface.

[0010] Furthermore, the first and second holes are formed in the inner wall portion that constitutes the inner side in the sheet width direction of the insertion portion of the resin lever. The first hole is formed in connection with the upper wall surface formed in the insertion portion of the resin lever, with a portion of the upper wall surface exposed, and the second hole is formed in connection with the lower wall surface formed in the insertion portion of the resin lever, with a portion of the lower wall surface exposed.

[0011] In this configuration, the insertion portion of the metal lever is inserted into the insertion portion of the resin lever, so the inside of the insertion portion of the resin lever is not visible from the outside. In this embodiment, a first hole connecting to the upper wall surface of the insertion portion and a second hole connecting to the lower wall surface of the insertion portion are formed in the inner wall of the insertion portion of the resin lever, respectively, so that the upper wall surface and the lower wall surface can be exposed through the first hole and the second hole.

[0012] In other words, in this embodiment, the positions of the upper and lower wall surfaces can be determined through the first and second holes, respectively. Therefore, in the part of the resin lever to be inserted, it is possible to measure the distance between the upper and lower wall surfaces (dimension L1) before inserting the insertion part of the metal lever. As a result, by measuring the distance between the first and second protrusions (dimension L2) in the insertion part of the metal lever, it is possible to determine whether dimension L2 can be fitted to dimension L1.

[0013] In this way, by pre-measuring the distance between the upper and lower wall surfaces (dimension L1) of the insertion portion of the resin lever, and the distance between the first and second protrusions (dimension L2) of the insertion portion of the metal lever, it becomes possible to easily control the dimensions to prevent looseness between the metal lever and the resin lever.

[0014] In the second embodiment, the operating lever is such that, in the first embodiment, the first hole and the second hole are located at the back of the insertion portion in the insertion direction.

[0015] In the operating lever according to the second embodiment, the first hole and the second hole are provided at the rear of the insertion portion in the insertion direction, making it possible to measure the distance between the upper wall surface and the lower wall surface at the rear of the portion to be inserted into the resin lever.

[0016] In the third embodiment, the operating lever is provided such that the first and second protrusions are arranged along the width direction of the insertion portion, as in the operating lever according to the first or second embodiment.

[0017] In the operating lever according to the third embodiment, the first and second protrusions are provided along the width direction of the insertion portion of the metal lever, making it easier to measure the distance between the first and second protrusions compared to the case where the first and second protrusions are formed at different positions along the insertion direction of the metal lever.

[0018] The operating lever according to the fourth embodiment is an operating lever according to any one of the first to third embodiments, wherein the first hole and the second hole are rectangular in shape along the insertion direction of the insertion portion.

[0019] In the operation lever according to the fourth aspect, the first hole portion and the second hole portion are formed in a rectangular shape along the insertion direction of the insertion portion of the metal lever, so that, for example, compared with a case where they are formed in an arc shape along the insertion direction (comparative example), the separation distance between the upper wall surface and the lower wall surface measured through the first hole portion and the second hole portion can be made substantially the same regardless of which position along the insertion direction is measured. That is, in this aspect, the measurement accuracy can be improved as compared with the comparative example.

[0020] A vehicle seat according to a fifth aspect includes a seat cushion that supports the buttocks of a seated occupant from the seat lower side, a seat back that supports the back of the seated occupant from the seat rear side, and the operation lever according to any one of claims 1 to 4.

[0021] In the vehicle seat according to the fifth aspect, by using the operation lever according to any one of the first to fourth aspects, the dimensions between the metal lever and the resin lever can be easily managed, and the cost can be reduced accordingly.

[0022] In the vehicle seat according to a sixth aspect, in the vehicle seat according to the fifth aspect, the operation lever is applied to a lifter lever that moves the seat cushion up and down.

[0023] In the vehicle seat according to the sixth aspect, the operation lever is a lifter lever, and the seat cushion is moved up and down by the lifter lever. Effects of the Invention

[0024] As described above, the operation lever and the vehicle seat according to the present invention have an excellent effect that the dimensions can be easily managed so that no rattling occurs between the metal lever and the resin lever. Brief Description of the Drawings

[Mode for Carrying Out the Invention]

[0026] Hereinafter, the vehicle seat according to the embodiment of the present invention will be described with reference to the drawings. Note that the arrow FR appropriately shown in the following drawings indicates the front direction in the vehicle longitudinal direction (the direction the seated person faces), the arrow UP indicates the upward direction in the vehicle vertical direction, and the arrow RH indicates the right direction in the vehicle width direction. Hereinafter, when the description is made simply using the front-rear, up-down, and left-right directions, unless otherwise specified, the front and rear in the seat longitudinal direction, the up and down in the seat vertical direction, and the left and right in the seat width direction when facing the traveling direction of the vehicle are indicated.

[0027] <Configuration of Vehicle Seat> First, the configuration of the vehicle seat according to the present embodiment will be described.

[0028] As shown in FIG. 1, the vehicle seat 10 according to the present embodiment includes a seat cushion 12 for an occupant to sit on, and a seat back 14 whose lower end portion is connected to the rear end portion of the seat cushion 12 to support the upper body of the occupant, and a headrest 16 is attached to the upper end portion of the seat back 14.

[0029] Here, the vehicle seat 10 is equipped with a reclining mechanism 18 at the lower end of the seat back 14. The lower end of the seat back 14 is connected to the rear end of the seat cushion 12 via this reclining mechanism. The reclining mechanism 18 is also equipped with a reclining lever 20, and by operating the reclining lever 20, the seat back 14 can be rotated relative to the seat cushion 12.

[0030] Furthermore, the vehicle seat 10 is equipped with a seat slide mechanism 22 at the bottom of the seat cushion 12. This seat slide mechanism 22 is equipped with a slide lever 24, and by operating the slide lever 24, the vehicle seat 10 can be moved in the front-rear direction of the vehicle along a pair of left and right slide rails 26 that constitute the seat slide mechanism 22.

[0031] Furthermore, the vehicle seat 10 includes a seat cushion frame 28 which serves as the skeletal member of the seat cushion 12, and a seat lifter mechanism 30 is provided between the seat cushion frame 28 and the seat slide mechanism 22. The seat lifter mechanism 30 is equipped with a lifter lever (operating lever) 32, and by rotating the lifter lever 32, the seat cushion 12 can be moved up and down relative to the slide rail 26.

[0032] The outer portion of the seat cushion 12 is provided with elongated plate-shaped side finishers 34 that extend along the front-to-back direction of the seat. These side finishers 34 are made of, for example, a resin material and are formed into a predetermined shape by injection molding. The side finishers 34 are provided on both outer sides in the width direction of the seat cushion 12 and cover the seat side frames (not shown), which constitute both sides of the seat cushion frame 28 and extend along the front-to-back direction of the seat, from the outside.

[0033] In this embodiment, the reclining lever 20 and the lifting lever 32 are provided on the right-side side finisher 34 of the vehicle seat 10, but this is not the only configuration. For example, on the passenger side, the reclining lever 20 is provided on the left-side side finisher 34. Also, in left-hand drive vehicles, the reclining lever 20 and the lifting lever 32 are provided on the left-side side finisher 34.

[0034] Now, let's explain the lifter lever 32. As shown in Figures 1 and 2, the lifter lever 32 is composed of a resin lever 36 made of resin that constitutes the design of the lifter lever 32, and a metal lever 38 made of metal that constitutes the skeletal member of the lifter lever 32.

[0035] Figure 3 shows an exploded perspective view of the lifter lever 32, showing the resin lever 36 and metal lever 38 that constitute the lifter lever 32, viewed from the inside in the seat width direction and diagonally to the rear. Figure 4 shows a schematic side view of the lifter lever 32, viewed from the inside in the seat width direction.

[0036] As shown in Figures 3 and 4, the metal lever 38 is formed in a crank shape, and a pivot plate 40 is provided at the rear end of the metal lever 38 in the front-rear direction of the seat, and is rotatably supported around a shaft portion (not shown) provided along the width direction of the seat.

[0037] On the other hand, the front end of the metal lever 38 in the front-rear direction of the seat is an insertion portion 42, which is formed along the front-rear direction of the seat and is insertable into an insertion portion 44 provided on the resin lever 36. A round hole portion 46 is formed at the tip of the insertion portion 42, and a rectangular projection portion 48 is provided on the rear side of the round hole portion 46, on the inside in the seat width direction. Between the insertion portion 42 and the pivot plate 40, there is a bent portion 50 that bends in a roughly L shape, and a roughly L-shaped convex bead 52 is formed on the bent portion 50 along the shape of the bent portion 50. This convex bead 52 protrudes outward in the seat width direction along the plate thickness direction of the metal lever 38, and the rigidity of the bent portion 50 is improved by increasing the plate thickness.

[0038] On the other hand, the insertion portion 42 of the metal lever 38 has a protrusion (first protrusion) 54A on the rear side of the seat of the protruding portion 48, which protrudes upward toward the seat at the upper end 54 of the insertion portion 42, and a protrusion (second protrusion) 56A on the lower end 56 of the insertion portion 42, which protrudes downward toward the seat.

[0039] In other words, the protrusion 54A protrudes upward from the upper end 54 in the width direction of the insertion portion 42, which is substantially perpendicular to the insertion direction of the insertion portion 42, and the protrusion 56A protrudes downward from the lower end 56 in the width direction of the insertion portion 42. The protrusions 54A and 56A are provided along the width direction of the insertion portion 42.

[0040] On the other hand, the resin lever 36 is composed of an outer wall portion 58 positioned on the outside in the width direction of the seat, an inner wall portion 60 positioned on the inside in the width direction of the seat and positioned so as to face the outer wall portion 58, an upper wall portion 62 connecting the outer wall portion 58 and the inner wall portion 60 and forming the upper end, and a lower wall portion 64 positioned so as to face the upper wall portion 62 and connecting the outer wall portion 58 and the inner wall portion 60 and forming the lower end, and is box-shaped with an opening on the rear side of the seat. Ribs 66 are placed between the outer wall portion 58 and the inner wall portion 60, and multiple ribs are arranged along the vertical direction of the seat to suppress deformation of the resin lever 36 and improve rigidity.

[0041] Here, the inner wall portion 60 is provided with an insertion portion 44 into which the insertion portion 42 of the metal lever 38 can be inserted. The insertion portion 44 is composed of the inner wall portion 60 and an insertion portion inner wall 68 which is capable of facing the inner wall portion 60 and is positioned further inward in the sheet width direction than the inner wall portion 60.

[0042] Furthermore, the insertion portion 44 has an upper wall surface 70 that can face the upper end 54 of the insertion portion 42 of the metal lever 38 and a lower wall surface 72 that can face the lower end 56, and the insertion portion 42 of the metal lever 38 is guided inward into the insertion portion 44 by the upper wall surface 70 and the lower wall surface 72.

[0043] Furthermore, a rectangular engagement hole 74 is formed in the inner wall 68 of the insertion portion behind the insertion portion 44, and the protruding portion 48 of the metal lever 38 can engage with this engagement hole 74. In this way, the metal lever 38 is fixed to the resin lever 36 with the protruding portion 48 of the metal lever 38 engaged with the engagement hole 74.

[0044] Here, as shown in Figures 3 and 5(A), a slit 76 is formed in the inner wall 68 of the insertion portion, extending along the front-rear direction of the sheet toward the upper wall surface 70. At the far end of the slit 76, a rectangular hole (first hole) 78 is formed, protruding toward the upper side of the sheet and connecting to the upper wall surface 70. In other words, the upper wall surface 70 can be exposed through this hole 78, and the position of the upper wall surface 70 can be determined.

[0045] Furthermore, a slit 80 extending along the front-to-back direction of the sheet is formed on the lower wall surface 72 side of the inner wall 68 of the insertion portion, and a rectangular hole (second hole) 82 is formed at the far end of the slit 80, protruding downward toward the sheet and connecting to the lower wall surface 72. In other words, the lower wall surface 72 can be exposed through this hole 82, and the position of the lower wall surface 72 can be determined.

[0046] Furthermore, the inner wall portion 60 of the resin lever 36 is provided with a pair of guide ribs 84 that protrude toward the inner wall 68 of the insertion portion and are aligned with the insertion direction of the metal lever 38. The pair of guide ribs 84 improve the rigidity of the insertion portion 44.

[0047] <Function and Effects of Vehicle Seats> Next, the operation and effects of the vehicle seat according to this embodiment will be described.

[0048] As shown in Figure 2, in this embodiment, the lifter lever 32 of the vehicle seat 10 comprises a metal lever 38 and a resin lever 36. The metal lever 38 serves as the skeletal member of the lifter lever 32, and the resin lever 36 is integrated with the metal lever 38 when the metal lever 38 is inserted into it, thus forming the design of the lifter lever 32.

[0049] Here, as shown in Figures 3 and 4, the metal lever 38 is composed of an insertion portion 42, a protrusion 54A, and a protrusion 56A, with the insertion portion 42 being inserted into the insertion portion 44 of the resin lever 36. The protrusions 54A and 56A are formed on the insertion portion 42 of the metal lever 38, respectively. The protrusion 54A protrudes upward from the upper end 54 in the width direction of the insertion portion 42, which is substantially perpendicular to the insertion direction of the insertion portion 42, and the protrusion 56A protrudes downward from the lower end 56 in the width direction of the insertion portion 42.

[0050] Furthermore, the resin lever 36 is composed of an insertion portion 44, an upper wall surface 70, a lower wall surface 72, a hole 78, and a hole 82, and the insertion portion 42 of the metal lever 38 can be inserted into the insertion portion 44.

[0051] The upper wall surface 70 is formed in the insertion portion 44 of the resin lever 36 along the insertion direction of the insertion portion 42 of the metal lever 38. When the insertion portion 42 of the metal lever 38 is inserted into the insertion portion 44 of the resin lever 36, the protrusion 54A formed on the upper end 54 of the metal lever 38 comes into contact with the upper wall surface 70.

[0052] Furthermore, the lower wall surface 72 is formed in the insertion portion 44 of the resin lever 36 along the insertion direction of the insertion portion 42 of the metal lever 38. When the insertion portion 42 of the metal lever 38 is inserted into the insertion portion 44 of the resin lever 36, the protrusion 56A formed on the lower end 56 of the metal lever 38 comes into contact with the lower wall surface 72.

[0053] Furthermore, the holes 78 and 82 are formed in the inner wall 68 of the insertion portion 44 of the resin lever 36, which constitutes the inner side in the sheet width direction. The hole 78 is formed in connection with the upper wall surface 70 formed in the insertion portion 44 of the resin lever 36, with a part of the upper wall surface 70 exposed, and the hole 82 is formed in connection with the lower wall surface 72 formed in the insertion portion 44 of the resin lever 36, with a part of the lower wall surface 72 exposed.

[0054] In this embodiment, the insertion portion 42 of the metal lever 38 is inserted into the insertion portion 44 of the resin lever 36, so the inside of the insertion portion 44 of the resin lever 36 is not visible from the outside. In this embodiment, a hole 78 connecting to the upper wall surface 70 of the insertion portion 44 and a hole 82 connecting to the lower wall surface 72 of the insertion portion 44 are formed in the inner wall 68 of the insertion portion 44 of the resin lever 36, respectively, so that the upper wall surface 70 and the lower wall surface 72 can be exposed through the holes 78 and 82, respectively.

[0055] In other words, in this embodiment, as shown in Figures 3, 4, and 5(A), the positions of the upper wall surface 70 and the lower wall surface 72 can be determined through the holes 78 and 82, respectively. Therefore, in the insertion portion 44 of the resin lever 36, it is possible to measure the distance (dimension L1) between the upper wall surface 70 and the lower wall surface 72 before inserting the insertion portion 42 of the metal lever 38.

[0056] Then, by measuring the distance (dimension L2) between the protrusions 54A and 56A in the insertion portion 42 of the metal lever 38, it becomes possible to determine whether or not the insertion portion 42 of the metal lever 38 can be fitted to the insertion portion 44 of the resin lever 36.

[0057] In this way, by pre-measuring the distance between the upper wall surface 70 and the lower wall surface 72 of the insertion portion 44 of the resin lever 36 (dimension L1), and the distance between the protrusions 54A and 56A of the insertion portion 42 of the metal lever 38 (dimension L2), it becomes possible to easily control the dimensions to prevent looseness between the metal lever 38 and the resin lever 36.

[0058] Therefore, compared to checking for looseness after assembling the metal lever 38 and the resin lever 36, the work efficiency is improved, and as a result, it is possible to reduce costs for the lifter lever 32.

[0059] Furthermore, in this embodiment, by forming holes 78 and 82 in the inner wall 68 of the insertion portion 44 of the resin lever 36, it is convenient that the distance between the upper wall surface 70 and the lower wall surface 72 within the insertion portion 44 (dimension L1) can be measured.

[0060] Furthermore, in this embodiment, since the holes 78 and 82 are provided at the rear of the insertion portion 42 in the insertion direction, it becomes possible to measure the distance (dimension L1) between the upper wall surface 70 and the lower wall surface 72 at the rear of the insertion portion 44 of the resin lever 36.

[0061] Furthermore, in this embodiment, since the protrusions 54A and 56A are provided along the width direction of the insertion portion 42 of the metal lever 38, it becomes easier to measure the distance between the protrusions 54A and 56A (dimension L2) compared to the case where the protrusions 54A and 56A are formed at different positions along the insertion direction of the metal lever 38.

[0062] In this embodiment, as described above, the insertion portion 42 of the metal lever 38 is provided with a protrusion 54A at the upper end 54 and a protrusion 56A at the lower end 56, and the protrusions 54A and 56A are set to abut against the upper wall surface 70 and the lower wall surface 72 of the insertion portion 44 of the resin lever 36, respectively.

[0063] As a result, in this embodiment, the metal lever 38 only needs to ensure dimensional accuracy at the protrusions 54A and 56A. In other words, the dimensional accuracy of the upper end 54 and lower end 56 of the insertion portion 42 does not need to be precise, so the area requiring dimensional accuracy can be narrowed compared to the case where the upper end 54 and lower end 56 abut against the upper wall surface 70 and lower wall surface 72, and thus costs can be reduced.

[0064] Furthermore, in this embodiment, as shown in Figures 3 and 5(A), the holes 78 and 82 are rectangular in shape along the insertion direction of the insertion portion 42 of the metal lever 38. For example, as a comparative example, as shown in Figure 5(B), if the holes 100 and 102 are formed in an arc shape along the insertion direction of the insertion portion 42 of the metal lever 38, the distance between the holes 100 and 102 will be L3, L4, and L5, respectively, and their dimensions will differ.

[0065] In contrast, in this embodiment, as shown in Figure 5(A), the holes 78 and 82 are rectangular in shape along the insertion direction of the insertion portion 42 of the metal lever 38. Therefore, regardless of the position measured along the insertion direction of the insertion portion 42 of the metal lever 38, the distance L1 between the upper wall surface 70 and the lower wall surface 72 measured through the holes 78 and 82 can be made approximately the same. In other words, this embodiment makes it possible to improve the measurement accuracy compared to the comparative example.

[0066] In the embodiments described above, an example in which the operating lever is applied to the lifter lever 32 shown in Figure 1 was explained, but it is not limited to this. For example, it may also be applied to the reclining lever 20.

[0067] Furthermore, the present invention is not limited to the embodiments described above, and can be implemented with various modifications without departing from the spirit of the invention. It goes without saying that the scope of the rights of the present invention is not limited to the embodiments described above. [Explanation of symbols]
