Description

Technical Field

[0001] The present invention relates to a vehicle seat, and particularly to an operation lever for rotating an operation shaft of a seat adjustment mechanism.

Background Art

[0006] The operating lever in the first embodiment is an operating lever for rotating the operating shaft of a seat adjustment mechanism provided on a vehicle seat, and is mounted integrally with the operating shaft so as to be rotatable. vehicle The device comprises: a stopper having an elastically deformable locking claw that restricts the range of rotation by engaging with the frame of the seat; a lever body attached to the stopper, having a locking hole into which the locking claw is inserted, and which is locked to the stopper by the locking claw catching on the edge of the locking hole; and a cap attached to the lever body that maintains the locked state by restricting the elastic deformation of the locking claw.

[0007] According to the first embodiment, the operating lever for rotating the operating shaft of a seat adjustment mechanism provided in a vehicle seat comprises a stopper, a lever body, and a cap. The stopper is mounted integrally with the operating shaft so as to be rotatable, and its range of rotation is limited by engaging with the frame of the vehicle seat, and it has an elastically deformable locking claw. The lever body is attached to the stopper and has a locking hole into which the locking claw is inserted, and the lever body is locked to the stopper by the locking claw catching on the edge of the locking hole. The cap is attached to the lever body and maintains the above-mentioned locked state by limiting the elastic deformation of the locking claw. This prevents the lever body from falling off the stopper. In this embodiment, since the lever body is attached to the operating shaft via the stopper, the strength of the lever body can be reduced compared to the case in which the lever body is directly attached to the operating shaft.

[0008] In the second embodiment, the operating lever, in the first embodiment, has a plurality of locking claws arranged in the circumferential direction of the operating shaft, and the lever body is , multiple Number The aforementioned The cap has a plurality of locking holes into which the locking claws are inserted, and the cap is , multiple Number The aforementioned It has ribs that limit the elastic deformation of the locking claw.

[0009] According to the second embodiment, the stopper has multiple locking claws arranged in the circumferential direction of the operating shaft, and the multiple locking claws are inserted into multiple locking holes in the lever body. When a cap is attached to the lever body, the elastic deformation of the multiple locking claws is restricted by ribs formed on the cap. This makes it possible to maintain the engagement state of the return portions of the multiple locking claws with respect to the edges of the multiple locking holes.

[0010] In the third embodiment, the operating lever, in the first or second embodiment, is made of a resin with lower bending strength than the resin constituting the stopper.

[0011] In the third embodiment, the configuration is as described above, making it possible to reduce the manufacturing cost of the lever body while ensuring the strength of the stopper.

[0012] In the fourth embodiment, the operating lever, in the third embodiment, is made of a fiber-reinforced resin with a lower fiber content than the fiber-reinforced resin that constitutes the stopper.

[0013] In the fourth embodiment, since it is configured as described above, it becomes easier to set the bending strength of the lever body and the stopper.

[0014] The fifth embodiment of the vehicle seat comprises a seat body on which a vehicle occupant sits, having a seat adjustment mechanism, and an operating lever of any one of the first to fourth embodiments, on which the stopper is attached to the operating shaft of the seat adjustment mechanism.

[0015] In the fifth embodiment of the vehicle seat, a stopper for the operating lever is attached to the operating shaft of the seat adjustment mechanism provided on the seat body in which the occupant sits. Since this operating lever is one of the first to third embodiments, the aforementioned effects are obtained. [Effect of the Invention]

[0016] As described above, according to the operation lever and the vehicle seat according to the present invention, the strength of the lever body can be reduced. [Brief Description of the Drawings]

[0021] Hereinafter, a vehicle seat 10 according to one embodiment of the present invention will be described with reference to Figures 1 to 12. In each figure, some reference numerals may be omitted for the sake of clarity. Also, the arrows FR, LH, and UP indicated as appropriate in each figure indicate the front, left, and top of the vehicle seat 10, respectively. Hereafter, when simply referring to the front, back, left, right, up, and down directions, unless otherwise specified, these directions refer to the direction relative to the vehicle seat 10.

[0019] As shown in Figure 1, the vehicle seat 10 according to this embodiment is, for example, the driver's seat of a so-called right-hand drive vehicle, and comprises a seat body 12 on which the occupant sits, and a reclining lever 50 which is an operating lever. The seat body 12 comprises a seat cushion 14 that supports the occupant's buttocks and thighs, a seat back 16 that supports the occupant's back, a headrest 18 that supports the occupant's head, a slide mechanism 36 for adjusting the front-to-back position of the seat body 12 relative to the vehicle, a lifter mechanism 38 for adjusting the up-to-down position of the seat body 12 relative to the vehicle, and a reclining mechanism 40 for adjusting the reclining angle of the seat back 16 relative to the seat cushion 14. The reclining mechanism 40 corresponds to the "seat adjustment mechanism" in this invention.

[0020] As shown in Figure 2 To that end, the cushion frame 20 that constitutes the skeleton of the seat cushion 14 comprises a pair of left and right side frames 22, a front frame 24 connecting the front ends of the left and right side frames 22 in the left-right direction, a rear frame 26 connecting the rear ends of the left and right side frames 22 in the left-right direction, and a pair of left and right B brackets 28 (the left B bracket 28 is not shown) fixed to the rear ends of the left and right side frames 22. The back frame 30 that constitutes the skeleton of the seat back 16 comprises a pair of left and right side frames 32 (the left side frame 32 is not shown), a lower frame 34 connecting the lower ends of the left and right side frames 32 in the left-right direction, and an upper frame (not shown) connecting the upper ends of the left and right side frames 32 in the left-right direction.

[0021] As shown in Figures 2 to 4, the lower end of the right side frame 32 is positioned to the left (inward in the seat width direction) relative to the right B bracket 28. Between the lower end of the right side frame 32 and the right B bracket 28, the recliner 42, which constitutes the main part of the reclining mechanism 40, is positioned. Although not shown in the figures, the recliner 42 is also positioned between the left B bracket 28 and the left side frame 32. The left and right recliners 42 are connected in the left-right direction by a reclining rod 48, which is the operating shaft. A reclining lever 50 is attached to the reclining rod 48. The reclining rod 48 and the reclining lever 50 constitute a part of the reclining mechanism 40.

[0022] The left and right ends of the reclining rod 48 are flattened into a roughly triangular cross-section. The right end of the reclining rod 48 passes through the lower end of the right side frame 32, the right recliner 42, and the right B bracket 28, and protrudes to the right (outward in the seat width direction) relative to the right B bracket 28. The left end of the reclining rod 48 passes through the lower end of the left side frame 32, the left recliner 42, and the left B bracket 28, and protrudes to the left (outward in the seat width direction) relative to the left B bracket 28.

[0023] Rotating members 44 (see Figures 3 and 4) are provided at the axis of the left and right recliners 42, with the left and right ends of the reclining rod 48 fitted into them. When these rotating members 44 rotate together with the reclining rod 48, the locks on the left and right recliners 42 are released, and the reclining angle of the seat back 16 can be adjusted. In Figures 3 and 4, 17 is a torsion coil spring that biases the seat back 16 in the upright direction.

[0024] The reclining lever 50 is positioned to the right of the right-side B bracket 28 and is attached to the right end of the reclining rod 48. This reclining lever 50 is an operating lever for rotating the reclining rod 48. As shown in Figures 1 to 6, this reclining lever 50 includes a stopper 52, a lever body 74, and a cap 92.

[0025] As shown in Figures 7 and 8, the stopper 52 is a substantially bottomed cylindrical shape having a peripheral wall portion 54 and a bottom wall portion 56. This stopper 52 is made of glass fiber reinforced resin and is positioned coaxially with the reclining rod 48 with the opening of the peripheral wall portion 54 facing left (inward in the seat width direction). A substantially triangular fitting hole 58 is formed in the center of the bottom wall portion 56, and a boss portion 60 (see Figure 7) protruding to the right (outward in the seat width direction) extends from the edge of the fitting hole 58. The right end of the reclining rod 48 is press-fitted inside this boss portion 60 and the fitting hole 58. As a result, the stopper 52 is attached to the reclining rod 48 so as to be integrally rotatable.

[0026] As shown in Figure 8, a substantially cylindrical inner wall portion 62 is coaxially provided inside the peripheral wall portion 54 of the stopper 52, and a plurality of (in this case, three) fixing claws 64 are provided inside the inner wall portion 62. The inner wall portion 62 and the fixing claws 64 extend integrally from the bottom wall portion 56. The plurality of fixing claws 64 are arranged in a line in the circumferential direction of the peripheral wall portion 54. Each fixing claw 64 is elastically deformable in the radial direction of the peripheral wall portion 54. A return portion (not shown) is formed at the tip of each fixing claw 64, protruding radially inward from the peripheral wall portion 54, and this return portion is fitted into a circumferential groove 46 (see Figures 3 and 4) formed in the rotating member 44 of the right-side recliner 42. This prevents the stopper 52 from coming off the right end of the reclining rod 48.

[0027] When the stopper 52 is attached to the right end of the reclining rod 48, the return portion of each fixing claw 64 slides against the rotating member 44, causing each fixing claw 64 to elastically deform radially outward of the reclining rod 48, then elastically return to its original position, and the return portion of each fixing claw 64 fits into the circumferential groove 46.

[0028] On the outside of the boss portion 60 of the stopper 52, there is an irregularly shaped fitting wall portion 66 that extends along the circumferential direction of the peripheral wall portion 54. The fitting wall portion 66 extends integrally from the bottom wall portion 56. Multiple (in this case, three) recesses 68 are formed in the fitting wall portion 66, recessed toward the boss portion 60, and are arranged in the circumferential direction. The three recesses 68 are arranged at equal or approximately equal intervals in the circumferential direction of the peripheral wall portion 54.

[0029] Each of the multiple recesses 68 is provided with a locking claw 70. The multiple (in this case, three) locking claws 70 extend integrally from the bottom wall 56 and are arranged at equal or approximately equal intervals in the circumferential direction of the peripheral wall 54. Each locking claw 70 is elastically deformable in the radial direction of the peripheral wall 54. The tip of each locking claw 70 has a return portion 70A that protrudes toward the opposite side from the fitting wall 66 (radially outward from the peripheral wall 54).

[0030] Furthermore, the bottom wall portion 56 has multiple (in this case, three) through holes 72 formed at locations offset in the circumferential direction from the three locking claws 70 in the peripheral wall portion 54. The multiple through holes 72 are positioned between the fitting wall portion 66 and the boss portion 60 when viewed from the axial direction of the peripheral wall portion 54, and penetrate the bottom wall portion 56. When viewed from the axial direction of the peripheral wall portion 54, the multiple through holes 72 have a substantially rectangular shape with the circumferential direction of the peripheral wall portion 54 as its longitudinal side.

[0031] A rotation limiting portion 54A is formed on a part of the peripheral wall portion 54, protruding radially outward from the peripheral wall portion 54. The rotation limiting portion 54A is arc-shaped when viewed from the axial direction of the peripheral wall portion 54 and opens toward the left side (inward in the seat width direction). As shown in Figures 3, 5, and 6, a rotation limiting piece 28A, provided at the upper end of the right B bracket 28, is inserted inside the rotation limiting portion 54A. The rotation limiting piece 28A protrudes toward the right side (outward in the seat width direction) from the upper end of the right B bracket 28, and is formed with a smaller circumferential dimension of the peripheral wall portion 54 than the rotation limiting portion 54A. When the stopper 52 rotates together with the reclining rod 48, the circumferential end of the rotation limiting portion 54A comes into contact with the rotation limiting piece 28A. This configuration limits the rotation range of the stopper 52, i.e., the reclining lever 50.

[0032] As shown in Figures 9 and 10, the lever body 74 has a roughly triangular (or trapezoidal) dish shape. This lever body 74 is made of glass fiber reinforced resin, and is positioned to the right of the stopper 52 (outside in the sheet width direction) with its thickness direction aligned with the left-right direction and opening toward the left. Honeycomb-shaped reinforcing ribs (not shown) are formed on the left side surface of the lever body 74. This lever body 74 is made of glass fiber reinforced resin with a lower glass fiber content than the glass fiber reinforced resin that makes up the stopper 52. For example, the glass fiber reinforced resin that makes up the stopper 52 has a glass fiber content of 60%, while the glass fiber reinforced resin that makes up the lever body 74 has a glass fiber content of 30%. As a result, the resin that makes up the lever body 74 has a lower bending strength than the resin that makes up the stopper 52. Note that the resins that make up the stopper 52 and the lever body 74 are not limited to glass fiber reinforced resin.

[0033] The lever body 74 has a shape in which the vertical dimension increases upward as it moves towards the rear. On the lower surface of the front part of the lever body 74 (i.e., the part of the lever body 74 with a smaller vertical dimension), there is a finger rest portion 74A, which is a recess for the occupant to place their fingers on when operating the lever body 74. On the upper part of the rear part of the lever body 74 (i.e., the part of the lever body 74 with a larger vertical dimension), there is a circular through hole 76. This through hole 76 is positioned coaxially with the reclining rod 48, and the right end of the reclining rod 48 is inserted into the through hole 76. On the right side surface of the upper part of the rear of the lever body 74, there is a recessed portion 78 that is recessed to the left. The recessed portion 78 is a stepped cylindrical shape concentric with the reclining rod 48, and the central part is recessed more deeply than the outer part.

[0034] Furthermore, an outer wall portion 80 is formed on the upper rear part of the lever body 74, projecting to the left (inward in the seat width direction). The outer wall portion 80 is a roughly cylindrical shape concentric with the reclining rod 48. Multiple (three in this case) protrusions 82 are formed on the inner circumference of the outer wall portion 80, projecting radially inward. The multiple protrusions 82 are arranged at equal or approximately equal intervals in the circumferential direction of the outer wall portion 80.

[0035] Multiple (three in this case) fitting portions 84 are provided on the inside of the outer wall portion 80. The multiple fitting portions 84 extend integrally from the edge of the through hole 76 in the lever body 74 and are arranged at equal or approximately equal intervals in the circumferential direction of the outer wall portion 80. The multiple fitting portions 84 are positioned offset in the circumferential direction of the outer wall portion 80 from the multiple protrusions 82 of the outer wall portion 80. The multiple fitting portions 84 are positioned between the multiple recesses 68 formed in the fitting wall portion 66 of the stopper 52 and are fitted to the inside of the fitting wall portion 66. The multiple protrusions 82 of the outer wall portion 80 are fitted into the multiple recesses 68 of the fitting wall portion 66. As a result, the lever body 74 is mounted integrally with the stopper 52 so as to be rotatable.

[0036] As shown in Figure 9, the lever body 74 has cap locking holes 86 where multiple fitting portions 84 are formed, each recessed to the left. Also, as shown in Figure 10, anti-tipping pieces 88 extend to the left from the tip surfaces of each of the multiple fitting portions 84. Each anti-tipping piece 88 is plate-shaped with the axial direction of the reclining rod 48 as its longitudinal direction and the radial direction of the reclining rod 48 as its thickness direction. The multiple anti-tipping pieces 88 are inserted through multiple through holes 72 of the stopper 52 and are positioned between the multiple fixing claws 64 of the stopper 52 and the inner wall portion 62. As a result, the multiple fixing claws 64 are restricted from elastically deforming the reclining rod 48 radially outward, and the state in which each return portion 64A of the multiple fixing claws 64 is fitted into the circumferential groove 46 of the rotating member 44 is maintained.

[0037] Multiple (three in this case) locking holes 90 are formed around the through hole 76 in the lever body 74. The multiple locking holes 90 are arranged at equal or approximately equal intervals in the circumferential direction of the through hole 76, and when viewed from the axial direction of the through hole 76, they form a rectangular shape with the circumferential direction of the through hole 76 as the longitudinal side. The multiple locking holes 90 are positioned offset in the circumferential direction of the through hole 76 relative to the multiple fitting portions 84. Multiple locking claws 70 formed on the stopper 52 are inserted into each of the multiple locking holes 90. The tips of the multiple locking holes 90 protrude into the recessed portion 78 of the lever body 74, and the return portions 70A formed on the tips of the multiple locking claws 70 catch on the edges of the multiple locking holes 90. As a result, the lever body 74 is locked to the stopper 52.

[0038] When the lever body 74 is attached to the stopper 52, the return portion 70A of each locking claw 70 slides against the edge of the locking hole 90, causing each locking claw 70 to elastically deform radially inward of the reclining rod 48 and then elastically return to its original position, so that the return portion 70A of each locking claw 70 catches on the edge of the locking hole 90.

[0039] As shown in Figures 11 and 12, the cap 92 is disc-shaped and is positioned coaxially with the reclining rod 48. This cap 92 is made of glass fiber reinforced resin and is fitted into the recess 78 of the lever body 74. This cap 92 is made of the same glass fiber reinforced resin as the lever body 74. This eliminates any change in appearance between the lever body 74 and the cap 92.

[0040] Multiple (in this case, three) hooking claws 94 are integrally formed on the left side (inward in the seat width direction) of the cap 92. The multiple hooking claws 94 are arranged at equal or approximately equal intervals in the circumferential direction of the reclining rod 48. The multiple hooking claws 94 are inserted into multiple cap locking holes 86 formed in the lever body 74. A return portion 94A is formed at the tip of each hooking claw 94, protruding radially outward from the cap 92. The return portion 94A of each hooking claw 94 is inserted into a slit 87 (see Figures 4 and 9) formed near the opening of each cap locking hole 86. This locks the cap 92 to the lever body 74.

[0041] Furthermore, a cylindrical rib 96 is integrally formed on the left side surface of the cap 92. This rib 96 is positioned coaxially with the reclining rod 48. As shown in Figure 4, this rib 96 is positioned close to and opposite the tips of the multiple locking claws 70 of the stopper 52 from the side opposite to the return portion 70A. This rib 96 restricts the elastic deformation of the multiple locking claws 70 toward the reclining rod 48. This ensures that the engagement state of the return portions 70A of the multiple locking claws 70 with respect to the edges of the multiple locking holes 90 is maintained.

[0042] Next, the operation and effects of the present invention will be described. In the vehicle seat 10 with the above configuration, a reclining lever 50 for rotating the reclining rod 48 is attached to the reclining rod 48 of the reclining mechanism 40 provided on the seat body 12 in which the occupant sits. This reclining lever 50 comprises a stopper 52, a lever body 74, and a cap 92.

[0043] The stopper 52 is integrally rotatably mounted to the reclining rod 48 and its range of rotation is limited by engaging with a B bracket 28, which is part of the cushion frame 20 of the vehicle seat 10. The stopper 52 is provided with an elastically deformable locking claw 70. The lever body 74 is attached to the stopper 52 and has a locking hole 90 into which the locking claw 70 is inserted. The lever body 74 is locked to the stopper 52 by the locking claw 70 catching on the edge of the locking hole 90.

[0044] The cap is attached to the lever body 74 and maintains the above-mentioned locking state by limiting the elastic deformation of the locking claw 70. This prevents the lever body 74 from falling off the stopper 52. In this reclining lever 50, since the lever body 74 is attached to the reclining rod 48 via the stopper 52, the strength of the lever body 74 can be reduced compared to when the lever body 74 is directly attached to the reclining rod 48.

[0045] Specifically, in this reclining lever 50, the locking claws 70 and hooking claws 94 are provided on the stopper 52 and cap 92, and the locking holes 90 and slits 87 that are mating to the locking claws 70 and hooking claws 94 are concentrated on the lever body 74. This allows the lever body 74 to be designated as a component that does not require high strength. As a result, the manufacturing cost of the lever body 74 can be reduced.

[0046] Furthermore, in this embodiment, the multiple locking claws 70 of the stopper 52 are arranged in the circumferential direction of the reclining rod 48, and the multiple locking claws 70 are inserted into the multiple locking holes 90 of the lever body 74. When the cap 92 is attached to the lever body 74, the elastic deformation of the multiple locking claws 70 is restricted by the rib 96 formed on the cap 92. This maintains the engagement state of the return portions 70A of the multiple locking claws 70 with respect to the edges of the multiple locking holes 90. Since the rib 96 is formed in an annular shape concentric with the reclining rod 48, when attaching the cap 92 to the lever body 74, it is not necessary to align the rib 96 with respect to the multiple locking claws 70 arranged in the circumferential direction of the reclining rod 48. This makes it easier to attach the cap 92 to the lever body 74.

[0047] Furthermore, in this embodiment, the lever body 74 is made of a glass fiber reinforced resin with a lower glass fiber content than the glass fiber reinforced resin that constitutes the stopper 52. Therefore, the resin that constitutes the lever body 74 is set to have a lower bending strength than the resin that constitutes the stopper 52. This makes it possible to reduce the manufacturing cost of the lever body 74 while ensuring the strength of the stopper 52 into which the reclining rod 48 is directly fitted. Moreover, it is easy to set the strength of both the lever body 74 and the stopper 52.

[0048] In the above embodiment, the rib 96 of the cap 92 is formed in an annular shape, but the shape of the rib can be changed as appropriate, and the embodiment is not limited to this.

[0049] Furthermore, in the above embodiment, the elastic deformation of the locking claw 70 is limited by the rib 96 formed on the cap 92, but the invention is not limited to this. For example, the elastic deformation of the locking claw may be limited by a protrusion formed on the cap 92.

[0050] Furthermore, although the above embodiment describes the case in which the present invention is applied to a reclining lever 50 attached to the reclining rod 48 (operating shaft) of a reclining mechanism 40, which is a seat adjustment mechanism, the present invention is not limited to this. For example, the present invention may also be applied to a lifter lever 98 (see Figure 1), which is an operating lever attached to the operating shaft of a lifter mechanism 38, which is a seat adjustment mechanism.

[0051] Furthermore, the present invention can be implemented with various modifications without departing from its spirit. Of course, the scope of the present invention is not limited to the embodiments described above. [Explanation of Symbols]
