Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above prior art, when screwing the outer cover to the seat cushion frame, the outer cover may rotate. In this case, the inner cover assembled to the outer cover via the claws and the claw receivers also rotates. That is, the side finisher may rotate and deviate from the target position of the design.

[0005] In consideration of the above facts, an object of the present invention is to provide a vehicle seat capable of preventing or suppressing the rotation of the side finisher with respect to the target position of the design.

Means for Solving the Problems

[0006] The vehicle seat according to the first embodiment includes an inside finisher which is screwed inward in the seat width direction to the rear end in the seat front-rear direction of a side frame provided along the seat front-rear direction on the outside in the seat width direction of the seat cushion frame which constitutes the frame of the seat cushion on which an occupant can sit, and which has a rotation stopper portion formed thereon which receives resistance from the side frame against the rotation direction of the screw fastening, and an outside finisher which is attachable to the inside finisher from the outside in the seat width direction to the rear end in the seat front-rear direction of the side frame, and which constitutes a design surface.

[0007] The vehicle seat according to the first embodiment includes an inside finisher and an outside finisher. A side frame is provided along the front-rear direction of the seat on the outside of the seat cushion frame, which constitutes the frame of the seat cushion on which an occupant can sit, in the seat width direction. The inside finisher is screwed to the rear end of this side frame in the seat width direction, on the inside in the seat width direction.

[0008] In this embodiment, a rotation-preventing portion is formed on the inside finisher. When the inside finisher is screwed in, if the screw head comes into contact with the inside finisher, the inside finisher may rotate along the direction of rotation of the screw due to frictional force.

[0009] Therefore, in this embodiment, the rotation-preventing part is configured to receive a counterforce from the side frame against the rotation direction of the inside finisher when it is screwed in. As a result, in this embodiment, it is possible to prevent the inside finisher from rotating when it is screwed in.

[0010] Furthermore, in this embodiment, the outside finisher is attached to the inside finisher from the outside in the seat width direction, relative to the rear end of the side frame in the seat front-rear direction, and constitutes a design surface. As mentioned above, by suppressing the rotation of the inside finisher when screwing it in, it becomes possible to secure the intended design position for the outside finisher attached to the inside finisher.

[0011] The vehicle seat according to the second embodiment is configured such that, in the vehicle seat according to the first embodiment, the rotation stopper portion includes a locking piece that can be locked so as to cover the upper end of the side frame from above in the vertical direction of the seat.

[0012] In the vehicle seat according to the second embodiment, the rotation stopper is configured to include a locking piece, which can be locked to the upper end of the side frame from above in the vertical direction of the seat. As a result, when the inside finisher is screwed to the side frame, the locking piece receives resistance from the side frame against the rotation direction of the inside finisher.

[0013] Therefore, in this embodiment, the locking piece suppresses the rotation of the inside finisher, and the locking piece allows the inside finisher to be temporarily fixed to the side frame, thereby improving work efficiency.

[0014] The third embodiment of the vehicle seat is a vehicle seat according to the first or second embodiment, wherein the rotation stopper is formed on the opposite side of the locking piece along the front-rear direction of the seat, with a fixing portion screwed to the inside of the side frame in the seat width direction, and includes a contact rib that can contact the side frame.

[0015] In the third embodiment of the vehicle seat, the rotation-preventing portion is configured to include a contact rib, which is formed on the opposite side of the locking piece along the front-rear direction of the seat, with a fixing portion that is screwed to the inside of the seat in the width direction of the side frame in between, and contacts the side frame to prevent rotation.

[0016] Generally, side finishers are installed on the side frames of the seat cushion frame, but the side frames are located on the right and left sides of the vehicle seat. Therefore, when screwing the inside finisher to the side frame, the direction of rotation is opposite on the right and left sides of the vehicle seat.

[0017] In this embodiment, a contact rib is formed on the opposite side of the locking piece along the front-rear direction of the seat, with the fixing portion of the inside finisher in between. As a result, the locking piece or the contact rib receives a resistive force from the side frame depending on the rotation direction of the screw fastening of the inside finisher.

[0018] In other words, in this embodiment, it is possible to prevent the inside finisher from rotating regardless of the direction of rotation due to the screw fastening of the inside finisher, and the configuration of the inside finisher can be applied to the right and left sides of a vehicle seat.

[0019] A vehicle seat according to the fourth embodiment is a vehicle seat according to any one of the first to third embodiments, wherein the inside finisher comprises a first main body on which the fixing portion is formed, and an engaged portion provided outside the first main body in the seat width direction and into which the outside finisher engages, and the outside finisher comprises a second main body that can face the side frame, and an engaging portion provided inside the second main body in the seat width direction and into which the engaged portion engages.

[0020] In the vehicle seat according to the fourth embodiment, the inside finisher comprises a first main body and an engaged portion. The first main body has a fixing portion that is screwed to the side frame. The engaged portion is provided outside the first main body in the seat width direction, and the outside finisher can engage with it.

[0021] On the other hand, the outside finisher is composed of a second main body and an engaging portion. The second main body is designed to face the side frame, and the engaging portion is provided further inward in the seat width direction than the second main body and is designed to engage with the engaged portion.

[0022] In other words, the inside finisher is screwed to the side frame, and the engaging portion formed on the outside finisher is engaged with the engaging portion formed on the inside finisher. This makes it possible to integrate the inside finisher and the outside finisher into a single unit.

[0023] A vehicle seat according to the fifth embodiment is a vehicle seat according to any one of the first to fourth embodiments, wherein the engaged portion comprises at least a part thereof and includes a plurality of engaged holes formed along the outer shape of the inside finisher, and the engaged portion comprises at least a part thereof and includes a plurality of engaged claws that protrude from the inside of a flange portion that extends inward in the seat width direction from the outer edge of the second main body and engage with the plurality of engaged holes, respectively.

[0024] In the vehicle seat according to the fifth aspect, at least a part of the engaged portion is constituted by a plurality of engaged holes, and the plurality of engaged holes are formed along the outer shape of the inside finisher. On the other hand, at least a part of the engaging portion is constituted by a plurality of engaging claws, and the plurality of engaging claws project from the inside of a flange portion that projects from the outer edge of the second main body portion of the outside finisher toward the inside in the seat width direction, and are respectively engaged with the plurality of engaged holes. Thus, since the engaging claws project from the inside of the flange portion, for example, compared with the case where they project from the tip of the flange portion, the breakage of the engaging claws is suppressed because they are not exposed to the outside.

[0025] The vehicle seat according to the sixth aspect is the vehicle seat according to any one of the first aspect to the fifth aspect, wherein inside the flange portion, between the adjacent engaging claws, a holding portion that holds the tip portion of the engaged portion between the holding portion and the flange portion projects.

[0026] In the vehicle seat according to the sixth aspect, in the outside finisher, a holding portion projects from the inside of the flange portion, and the holding portion holds the tip portion of the engaged portion between the holding portion and the flange portion between the adjacent engaging claws.

[0027] That is, in this aspect, in a state where the engaged portion of the inside finisher and the engaging portion of the outside finisher are engaged, the tip portion of the engaged portion is set to be held between the flange portion and the holding portion of the outside finisher so that the tip portion of the engaged portion of the inside finisher is held. Thereby, the outside finisher is prevented from coming off with respect to the inside finisher, the engaging force between the inside finisher and the outside finisher is improved, and it becomes possible to improve the rigidity of the side finisher.

Effect of the Invention

[0028] As described above, according to the vehicle seat according to the present invention, the rotation of the side finisher can be prevented or suppressed with respect to the target position of the design. [Brief explanation of the drawing]

[0030] Hereinafter, a vehicle seat according to an embodiment of the present invention will be described with reference to the drawings. In the following figures, arrows FR, as appropriate, indicate the forward direction in the vehicle's longitudinal direction (the direction the seated person faces), arrows UP indicate the upward direction in the vehicle's vertical direction, and arrows RH indicate the rightward direction in the vehicle's width direction. Hereafter, when simply referring to the longitudinal, vertical, and left-right directions, unless otherwise specified, they refer to the longitudinal direction of the seat, the vertical direction of the seat, and the left-right direction in the seat's width direction when facing the direction of travel of the vehicle.

[0031] <Vehicle seat configuration> First, the configuration of the vehicle seat according to this embodiment will be described.

[0032] As shown in Figure 1, the vehicle seat 10 according to this embodiment comprises a seat cushion 12 for the occupant to sit on, and a seat back 14 whose lower end is connected to the rear end of the seat cushion 12 to support the occupant's upper body. A headrest 16 is attached to the upper end of the seat back 14. The front-rear, left-right, up-down directions of the vehicle seat 10 coincide with the front-rear, left-right, up-down directions of the vehicle, and this vehicle seat 10 is the right front seat of the vehicle. If this vehicle seat 10 is the left front seat of the vehicle, the configuration will be symmetrical to that of this embodiment.

[0033] The lower part of the seat cushion 12 is equipped with a well-known seat sliding mechanism, which connects the vehicle seat 10 to the floor of the vehicle body, and also allows the vehicle seat 10 to move in the front-rear direction of the vehicle.

[0034] Furthermore, the seat cushion 12 is equipped with a seat cushion frame 18 that constitutes the framework of the seat cushion 12. This seat cushion frame 18 has a substantially rectangular shape in plan view and is made of, for example, steel plate, aluminum alloy, etc. A seat cushion pad 20 made of a foamed material such as urethane foam is provided on the upper side of the seat cushion frame 18, and the surface of the seat cushion pad 20 is covered with a seat cushion surface 22 made of, for example, fabric, leather, synthetic leather, or PVC, etc.

[0035] On the other hand, the seat back 14 is equipped with a seat back frame 30 (see Figure 2) that constitutes the skeleton of the seat back 14. The seat back frame 30 is roughly rectangular in shape when viewed from the front, and a seat back pad 26 is provided on the front side of the seat back frame 30, similar to the seat cushion 12, and the surface of the seat back pad 26 is covered with a seat back surface 28.

[0036] On the outer side of the seat back frame 30 in the seat width direction, a seat back side frame 32 (see Figure 2) extends along the vertical direction of the seat. Although not shown, a reclining mechanism 34, including a well-known recliner, is provided at the lower right end of the seat back side frame 32. The seat back frame 30 is connected to the seat cushion frame 18 via this reclining mechanism 34.

[0037] The reclining mechanism 34 is equipped with a reclining lever (not shown), and by rotating this reclining lever, the seat back 14 can be tilted relative to the seat cushion 12. In this embodiment, the recliner is provided on the right side of the vehicle seat 10, but it is not limited to this and may be provided on the left side, or on both the right and left sides.

[0038] Here, as mentioned above, the seat cushion frame 18 shown in Figure 2 has a roughly rectangular shape in plan view, and the outer side of the seat cushion frame 18 in the seat width direction is provided with a seat side frame 36 that extends along the front-rear direction of the seat. Side finishers 40 are provided on the left and right sides of the vehicle seat 10 at the rear end 37 of this seat side frame 36 so as to cover the hinge portion 38 which constitutes part of the reclining mechanism 34.

[0039] As shown in Figures 2 and 3, this side finisher 40 is composed of an inner side finisher (hereinafter referred to as "inner finisher") 42 and an outer side finisher (hereinafter referred to as "outer finisher") 44.

[0040] The inner finisher 42 and the outer finisher 44 are molded from resin, respectively. The inner finisher 42 is attached to the seat side frame 36, which constitutes the outer side of the seat cushion frame 18 in the seat width direction and extends along the front-rear direction of the seat, on the inside in the seat width direction. On the other hand, the outer finisher 44 engages with the inner finisher 42 from the outside in the seat width direction and is attached to the seat side frame 36 on the outside in the seat width direction.

[0041] (Inner finisher) Now, let's explain the inner finisher 42.

[0042] As shown in Figures 2 and 3, the inner finisher 42 is formed in a curved shape that bulges upward toward the seat, and includes a main body portion (first main body portion) 46 that covers the inner surface 36A (see Figure 5) in the seat width direction of the seat side frame 36, and a flange portion (engaged portion) 48 that extends outward from the outer edge of the main body portion 46 in the seat width direction and covers the upper end of the seat side frame 36.

[0043] Furthermore, the inner finisher 42 is composed of an inclined portion (engaged portion) 50, an arc portion 52, and a hanging portion 54, in that order from the front side in the front-rear direction of the seat. The inclined portion 50 is inclined toward the upper side of the seat as the flange portion 48 moves toward the rear side in the front-rear direction of the seat, and the arc portion 52 is formed by curving so as to bulge toward the upper side of the seat. The hanging portion 54 is formed by hanging down toward the lower side of the seat from the rear end of the arc portion 52.

[0044] The main body portion 46 of the inner finisher 42 has a triangular shape in the inclined portion 50, with the flange portion 48 forming the slope when viewed from the side of the sheet. A locking piece (rotation stopper) 66 is formed at the front end portion 50A of the inclined portion 50 of the main body portion 46. The locking piece 66 extends outward from the main body portion 46 in the sheet width direction and is formed to curve downward toward the sheet, allowing it to lock onto the upper end portion 36C (see Figure 5) of the sheet side frame 36 by covering it from above the sheet.

[0045] Furthermore, a boss (fixing part) 56, which is substantially cylindrical and protrudes outward in the seat width direction, is provided at the rear end of the inclined portion 50 of the main body 46. The top surface 56A of this boss 56 is made capable of contacting the inner surface 36A (see Figure 5) of the seat side frame 36, although it is not shown in the figures. With the top surface 56A of the boss 56 in contact with the seat side frame 36, the boss 56 is screwed to the seat side frame 36 using tapping screws (not shown). This allows the inner finisher 42 to be fixed to the seat side frame 36.

[0046] Furthermore, a pair of inclined ribs (rotation stoppers) 58 are provided projecting outward in the sheet width direction from the inclined portion 50 side of the arc portion 52 of the main body portion 46. These inclined ribs 58 are formed to be inclined downward towards the sheet as they are directed towards the rear of the sheet, and these inclined ribs 58 are capable of contacting the inner surface 36A (see Figure 5) of the sheet side frame 36.

[0047] Furthermore, a hook-shaped locking rib 60 protrudes toward the front of the seat from the arc-shaped portion 52 side of the hanging portion 54 of the main body 46, and this locking rib 60 can be locked to the inner surface 36A (see Figure 5) of the seat side frame 36.

[0048] On the other hand, the flange portion 48 has multiple substantially rectangular engagement holes 62 formed at predetermined intervals on the outer side in the sheet width direction, extending from the inclined portion 50 to the hanging portion 54. The engagement claws (engagement parts) 64 (see Figure 4), which will be described later, formed on the outer finisher 44 (see Figure 4) can engage with these engagement holes 62. In addition, a guide portion 62A is formed on the outer side in the sheet width direction of the engagement holes 62, and the guide portion 62A is inclined toward the main body portion 46 as it extends outward in the sheet width direction, so that the engagement claws 64 are easily guided into the engagement holes 62.

[0049] Furthermore, a claw portion (engaged portion) 68 protrudes downward from the rear side of the seat of the locking piece 66 in the flange portion 48. This claw portion 68 is capable of engaging with a rectangular hole 96 (engaged portion), which will be described later, formed in the outer finisher 44 (see Figure 4).

[0050] Furthermore, a substantially cylindrical boss 70 is provided on the hanging portion 54 of the flange portion 48, projecting toward the front of the seat. The top surface 70A of this boss 70 is made capable of contacting the rear end surface (not shown) of the seat side frame 36, and with the top surface 70A of the boss 70 in contact with the seat side frame 36, the boss 70 is screwed to the seat side frame 36 by tapping screws (not shown).

[0051] This allows the inner finisher 42 to be fixed to the seat side frame 36. A bottom wall portion 72 is formed at the lower end of the flange portion 48, which connects to the main body portion 46, and this bottom wall portion 72 is set to cover the rear end of the seat side frame 36 from the lower side of the seat.

[0052] (Outer finisher) Next, we will explain the outer finisher 44.

[0053] As shown in Figures 2 and 4, the outer finisher 44 is designed to engage with the inner finisher 42 from the outside in the sheet width direction, and the outer shape of the outer finisher 44 is formed to match the outer shape of the inner finisher 42.

[0054] Therefore, the outer finisher 44 is formed in a curved shape that bulges upward toward the seat, and includes a main body portion (second main body portion) 74 that covers the outer surface 36B (see Figure 5) in the seat width direction of the seat side frame 36, and a flange portion (engaging portion) 76 that protrudes inward from the outer edge of the main body portion 74 in the seat width direction and covers the upper end of the seat side frame 36.

[0055] Furthermore, the outer finisher 44 is composed of a front portion 78 and a rear portion 80, and the rear portion 80 is formed to protrude more outward in the sheet width direction than the front portion 78. For this reason, an inclined wall 82 is provided between the front portion 78 and the rear portion 80 to connect the difference in the sheet width direction. The front portion 78 of the outer finisher 44 is capable of engaging with the inclined portion 50 of the inner finisher 42, and the rear portion 80 of the outer finisher 44 is capable of engaging with the arc portion 52 and the hanging portion 54 of the inner finisher 42.

[0056] As shown in Figure 4, a rectangular tubular base 84 is provided projecting inward in the seat width direction from the lower end of the front portion 78 of the main body 74. As shown in Figure 2, a through hole (not shown) is formed in the seat side frame 36, and a clip 85 is attached to this through hole. The base 84 is designed to accommodate this clip 85, and the outer finisher 44 is fixed to the outer surface 36B (see Figure 5) of the seat side frame 36 via the clip 85 and the base 84.

[0057] Furthermore, as shown in Figure 4, the main body 74 has multiple ribs 86 (three in this case) protruding in the vertical direction of the sheet, extending from the rear 80 side of the front 78 to the inclined wall 82, thereby ensuring rigidity in the inclined wall 82.

[0058] Furthermore, a boss 88 and a base 90 are provided protruding from the center of the rear portion 80 of the main body 74 in the vertical direction of the seat. The boss 88 abuts against a bracket 92 provided on the hinge portion 38 (see Figure 2), and the base 90, although not shown, is engaged with a clip that is engaged with the bracket 92 (see Figure 2), and is fixed to the bracket 92 via the clip. In other words, the boss 88 and the base 90 are each capable of abutting against the bracket 92, and the rigidity of the main body 74 is also ensured by these.

[0059] On the other hand, an extension piece 94 protrudes inward in the sheet width direction from the front portion 78 of the flange portion 76, and a rectangular hole 96 (engagement portion) is formed in the center of the extension piece 94, into which a claw portion 68 formed on the inner finisher 42 can engage, as shown in Figure 6. A guide portion 96A is formed on the inside of the rectangular hole 96 in the sheet width direction, and is inclined toward the downward side of the sheet as it moves inward in the sheet width direction, so that the claw portion 68 is easily guided into the rectangular hole 96 when the extension piece 94 moves inward in the sheet width direction relative to the claw portion 68.

[0060] Furthermore, as shown in Figure 4, the rear portion 80 of the flange portion 76 has multiple engaging claws 64 which engage with multiple engaging holes 62 formed in the inner finisher 42. Between the engaging claws 64, a retaining portion 98 is provided that protrudes toward the main body portion 74 (inward). In this embodiment, two retaining portions 98 are provided between the engaging claws 64, but this is not the only configuration.

[0061] A gap is provided between the tip portion 98A of the retaining portion 98 and the flange portion 76. As shown in Figure 7, with the engaging claw 64 engaged in the engaging hole 62 formed in the inner finisher 42, the tip portion of the flange portion 48 of the inner finisher 42 can be accommodated in the gap.

[0062] <Function and Effects of Vehicle Seats> Next, the operation and effects of the vehicle seat according to this embodiment will be described.

[0063] First, the method of attaching the side finisher 40 will be described. In this embodiment, as shown in Figure 2, an inner finisher 42 is attached to the inside of the seat side frame 36 in the seat width direction, and then an outer finisher 44 is engaged with the inner finisher 42 from the outside in the seat width direction.

[0064] In this embodiment, as shown in Figures 2 and 3, a locking piece 66 is formed on the front end portion 50A of the flange portion 48 of the inner finisher 42, and this locking piece 66 can be locked to the upper end portion 36C of the seat side frame 36. In addition, a locking rib 60 is formed on the hanging portion 54 of the main body portion 46 of the inner finisher 42, and this locking rib 60 can be locked to the inner surface 36A (see Figure 5) of the seat side frame 36.

[0065] With the locking piece 66 locked to the upper end portion 36C of the seat side frame 36 and the locking rib 60 locked to the inner surface 36A (see Figure 5) of the seat side frame 36, the top surface 56A of the boss 56 provided on the inclined portion 50 of the main body portion 46 of the inner finisher 42 is brought into contact with the inner surface 36A of the seat side frame 36, and the boss 56 is screwed to the seat side frame 36 with a tapping screw (not shown).

[0066] On the other hand, the top surface 70A of the boss 70 is designed to contact the rear end surface (not shown) of the seat side frame 36, although this is not shown. With the top surface 70A of the boss 70 in contact with the seat side frame 36, the boss 70 is screwed to the seat side frame 36 using tapping screws (not shown). In this way, the inner finisher 42 is fixed to the seat side frame 36.

[0067] Next, the outer finisher 44 is attached to the inner finisher 42 and the seat side frame 36.

[0068] As shown in Figures 2 and 4, a base 84 is formed on the front portion 78 of the outer finisher 44, and the outer finisher 44 is fixed to the outer surface 36B of the seat side frame 36 via a clip attached to the seat side frame 36 and the base 84.

[0069] Furthermore, a base 90 is provided at the rear 80 of the outer finisher 44, and the outer finisher 44 is fixed to the bracket 92 (see Figure 2) provided on the hinge portion 38 via a clip (not shown) and the base 90.

[0070] As shown in Figures 2 and 4, in this embodiment, the inner finisher 42 is provided with claws 68 and a plurality of engagement holes 62. On the other hand, the outer finisher 44 is provided with a rectangular hole 96 and a plurality of engagement claws 64. The claws 68 engage with the rectangular hole 96, and a guide portion 62A is formed on the outside of the engagement hole 62 in the sheet width direction, so that when the engagement claw 64 (see Figure 4) moves inward in the sheet width direction, the engagement claw 64 is smoothly guided into the engagement hole 62.

[0071] Furthermore, a guide portion 96A is formed on the inside of the rectangular hole 96 in the sheet width direction, so that when the extension piece 94 moves inward in the sheet width direction relative to the claw portion 68, the claw portion 68 is smoothly guided into the rectangular hole 96.

[0072] In other words, the rectangular holes 96 and multiple engaging claws 64 of the outer finisher 44 can be easily engaged (attached) to the inner finisher 42 simply by moving the outer finisher 44 from the outside to the inside in the sheet width direction, with respect to the claws 68 and multiple engaging holes 62 of the inner finisher 42.

[0073] Here, the operation and effects of the vehicle seat 10 according to this embodiment will be described. As shown in Figures 2 to 4, in this embodiment, a side finisher 40 is provided at the rear end 37 of the seat side frame 36. The side finisher 40 comprises an inner finisher 42 and an outer finisher 44, and the inner finisher 42 is screwed inward in the seat width direction to the rear end 37 of the seat side frame 36.

[0074] In this embodiment, the inner finisher 42 is provided with a locking piece 66 and an inclined rib 58 as anti-rotation parts. Although not shown in the figures, when the inner finisher 42 is screwed in, if the screw head comes into contact with the inner finisher 42, the inner finisher 42 may rotate along the direction of rotation of the screw due to frictional force. Therefore, in this embodiment, the locking piece 66 and the inclined rib 58 are configured to receive a resistive force from the seat side frame 36 against the direction of rotation of the inner finisher 42 when screwing it in.

[0075] As a result, in this embodiment, when the inner finisher 42 is screwed in, the locking piece 66 and the inclined rib 58 prevent the inner finisher 42 from rotating. In other words, according to this embodiment, the rotation of the side finisher 40 can be prevented or suppressed.

[0076] Furthermore, in this embodiment, the outer finisher 44 is attached to the inner finisher 42 from the outside in the seat width direction, relative to the rear end 37 of the seat side frame 36, and constitutes a design surface. As described above, by suppressing the rotation of the inner finisher 42 when screwing it in, it is possible to secure the intended design position of the outer finisher 44 attached to the inner finisher 42.

[0077] Furthermore, since the locking piece 66 can be locked to the upper end of the seat side frame 36 from above in the vertical direction of the seat, the inner finisher 42 can be temporarily fixed to the seat side frame 36 via the locking piece 66 when screwing the inner finisher 42 to the seat side frame 36, thereby improving work efficiency.

[0078] Here, the inclined rib 58 is formed on the opposite side of the locking piece 66 along the front-rear direction of the seat, with a boss 56 screwed to the seat side frame 36 in between, and contacts the seat side frame 36 to prevent rotation.

[0079] Generally, the side finisher 40 is installed on the seat side frame 36 of the seat cushion frame 18, but the seat side frame 36 is installed on the right and left sides of the vehicle seat 10. Therefore, the side finisher 40 is installed on the right and left sides of the vehicle seat 10, but when screwing the side finisher 40 to the seat side frame 36, the direction of rotation is opposite on the right and left sides of the vehicle seat 10.

[0080] In this embodiment, an inclined rib 58 is formed on the opposite side of the locking piece 66 along the front-rear direction of the seat, with a boss 56 formed on the inner finisher 42 in between. As a result, the locking piece 66 or the inclined rib 58 receives a resistive force from the seat side frame 36 depending on the rotation direction of the screw fastening of the inner finisher 42.

[0081] In other words, in this embodiment, it is possible to prevent the inner finisher 42 from rotating regardless of the direction of rotation due to the screw fastening of the inner finisher 42. Therefore, the configuration of the inner finisher 42 can be applied to the right and left sides of the vehicle seat 10.

[0082] In this embodiment, the inner finisher 42 is composed of a main body portion 46 and a flange portion 48. The main body portion 46 has a boss 56 that is screwed to the seat side frame 36. The flange portion 48 is provided on the outside in the seat width direction of the main body portion 46, and the outer finisher 44 can engage with the flange portion 48.

[0083] On the other hand, the outer finisher 44 is composed of a main body portion 74 and a flange portion 76. The main body portion 74 is designed to face the seat side frame 36, and the flange portion 76 is provided further inward in the seat width direction than the main body portion 74 and is designed to engage with the flange portion 48.

[0084] In other words, the inner finisher 42 is screwed to the seat side frame 36, and the flange portion 76 formed on the outer finisher 44 is engaged with the flange portion 48 formed on the inner finisher 42. This makes it possible to integrate the inner finisher 42 and the outer finisher 44.

[0085] Furthermore, in this embodiment, the flange portion 48 provided on the inner finisher 42 is configured to include a plurality of engagement holes 62 arranged along the outer shape of the inner finisher 42. On the other hand, the flange portion 76 provided on the outer finisher 44 has a plurality of engagement claws 64 protruding from the inside of the flange portion 76 which extends inward in the sheet width direction from the outer edge of the main body portion 74, and each of the plurality of engagement claws 64 is capable of engaging with a plurality of engagement holes 62. Since the engagement claws 64 protrude from the inside of the flange portion 76, for example, compared to the case where they protrude from the tip of the flange portion 76, the breakage of the engagement claws 64 is suppressed because they are not exposed to the outside.

[0086] Furthermore, in this embodiment, the outer finisher 44 is provided with a retaining portion 98 on the flange portion 76. The retaining portion 98 is formed between adjacent engaging claws 64, and the retaining portion 98 holds the tip portion 48A (see Figure 7) of the flange portion 48 of the inner finisher 42 between itself and the flange portion 76 of the inner finisher 42.

[0087] In other words, in this embodiment, with the flange portion 48 of the inner finisher 42 and the flange portion 76 of the outer finisher 44 engaged, the tip portion 48A of the flange portion 48 of the inner finisher 42 is positioned to be held between the flange portion 76 of the outer finisher 44 and the retaining portion 98. This prevents the inner finisher 42 from coming off, improves the engagement force between the inner finisher 42 and the outer finisher 44, and improves the rigidity of the side finisher 40.

[0088] It should be noted that 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. Furthermore, 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]
