Description

[Technical field]

[0001] The present invention relates to a sheet, and more particularly to a sheet having openings formed in its surface. [Background technology]

[0002] Some vehicle seats have openings such as a seat belt outlet and an air vent formed in the seat back or head rest. In order to maintain the shape of these openings, some have shape-retaining members attached to the openings formed in the skin (for example, Patent Documents 1 and 2). In Patent Document 1, a belt guide serving as a shape-retaining member is attached to the opening formed in the skin in order to form a seat belt outlet in the seat back. The belt guide is connected to the skin via a frame attached to the opening in the skin. A hook hole is provided on the periphery of the opening in the skin, and the frame is attached to the skin by hooking the hole onto a protrusion provided on the frame.

[0003] In Patent Document 2, a vent hole penetrating from front to rear is formed in the headrest, and a garnish acting as a shape-retaining member is attached to the opening in the skin. A hook hole is provided on the periphery of the opening in the skin, and the hook hole is hooked to a protrusion provided on the side of the garnish, thereby joining the garnish to the skin. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-181524 [Patent Document 2] JP 2006-43000 A Summary of the Invention [Problem to be solved by the invention]

[0005] The shape-retaining member may be made of a resin harder than the pad or the skin. In this case, when a pressure load is applied to the periphery of the opening, the pad or the skin deforms more than the shape-retaining member. This may cause a gap between the shape-retaining member and the skin, which may easily trap foreign objects. In addition, in Patent Documents 1 and 2, the hook holes provided in the skin are hooked onto protrusions provided on the garnish or the frame. Therefore, when a tensile force is applied to the skin, cracks may occur from the holes, which may damage the skin.

[0006] In view of the above background, an object of the present invention is to provide a seat having an opening formed in a cover and a garnish attached to the opening, the cover being resistant to damage. [Means for solving the problem]

[0007] In order to solve the above problem, a seat (S) is provided which has a frame (F3), a pad (36) supported by the frame, a skin (37) having a first opening (38) covering a surface of the pad, a plate-like plate (46) connected to the edge of the first opening on the back surface of the skin and having a second opening (47) facing the first opening, and a garnish (40) which has a body (41) passing through the first opening and the second opening, an extension (42) extending in a ring shape from the body to the edge surface of the first opening, and a locking portion provided on the body for locking the plate.

[0008] With this configuration, the plate connected to the skin is engaged with the garnish, so that even if a pressing load is applied to the peripheral edge of the first opening, the relative position of the plate to the garnish does not change, and gaps are less likely to occur between the skin and the garnish.

[0009] In the above configuration, the plate and the skin may be sandwiched between the extension and the locking portion.

[0010] According to this configuration, the configuration for locking the plate in the first opening can be simplified.

[0011] Furthermore, in the above configuration, the pad is connected to the front side of the frame, the front surface of the pad is covered by the skin, a third opening (39) is formed in the pad extending rearward from the first opening and penetrating from front to rear, a back cover covering the rear surface of the frame is connected to the rear side of the frame, and the body is connected to the back cover through the third opening.

[0012] According to this configuration, the pad is connected to the frame, and the garnish is connected to the frame via the back cover, so that the garnish is less likely to come off the pad.

[0013] Furthermore, in the above configuration, it is preferable that the front surface of the back cover has a connection portion (63) extending forward, the body portion is connected to the connection portion, an engagement hole (66) penetrating the wall surface is provided at the front end of the connection portion, and a locking claw (44A, 44C) is provided at the rear end of the body portion protruding from the body portion and engaging with the engagement hole.

[0014] According to this configuration, the rigidity of the seat is increased by joining the connecting portion and the trunk portion.

[0015] In addition, in the above configuration, a protrusion (45) protruding from an outer wall surface of the body is formed on the body, and the protrusion abuts against a wall surface of the third opening and restricts movement of the connection portion.

[0016] According to this configuration, since the connection portion is sandwiched between the protrusion and the body portion, distortion of the connection portion can be corrected.

[0017] In the above configuration, preferably, an outwardly extending notch (47C) is formed in the outer periphery of the second opening of the plate at a position corresponding to the protruding portion.

[0018] With this configuration, the protrusion passes through the notch, making it easier to move the plate along the body to between the extension and the engagement portion, and also making it easier to position the plate and garnish in the correct positions relative to each other.

[0019] In the above configuration, the garnish may be formed in a cylindrical shape with both ends open, and the connecting portion may be formed in a cylindrical shape with a rear end open at the back cover and a front end open.

[0020] According to this configuration, an air vent is formed penetrating the seat from front to rear.

[0021] In the above configuration, the plate may be sewn to the first opening.

[0022] According to this configuration, the plate and the skin can be strongly and easily bonded to each other.

[0023] In the above configuration, the plate may be sewn along a circumferential direction of the first opening.

[0024] According to this configuration, since the plate and the skin are joined at multiple points by the sutures, even if a tensile load is applied to the skin, the load is dispersed, making the skin less likely to break. Also, the plate and the skin can be joined more strongly.

[0025] In the above configuration, the plate may be formed with a cut portion (48) connecting an outer periphery and the second opening.

[0026] With this configuration, the plate can be deformed by widening the cut portion, making it easier to assemble the plate to the garnish. Furthermore, the cut portion makes it easier to move the sewing needle to the location where sewing begins.

[0027] In the above configuration, preferably, a mark (37C) is formed on the outer periphery of the first opening, and a notch (46C) recessed inward is formed on the outer periphery of the plate at a position corresponding to the mark.

[0028] According to this configuration, it becomes easy to join the plate and the skin so as to be in the appropriate position, and to join the plate and the garnish so as to be in the appropriate position. Effect of the Invention

[0029] According to the above-mentioned configuration, a seat is provided in which an opening is formed in the cover and a garnish is attached to the opening, and the cover is less likely to be damaged. [Brief description of the drawings]

[0031] An embodiment in which the seat according to the present invention is applied to a vehicle seat installed in an automobile will be described below with reference to Figs. 1 to 9. In the following description, left and right, and inside and outside are defined based on an occupant seated in the vehicle seat. A common number is given to a pair of left and right components, and when specifying the left and right, the letters left or right are added to the name of the component.

[0032] As shown in Fig. 1, the vehicle seat S is a so-called full bucket seat, and includes a seat cushion S1 and a seat back S2 in which a backrest S3 and a headrest portion S4 are integrally formed. The seat cushion S1 includes a seat cushion frame, and a pad and a cover covering the upper side of the seat cushion frame, and supports the buttocks and thighs of an occupant. The seat cushion frame is formed in a frame shape by a pair of left and right cushion side frames F2 extending in the front-rear direction, and a plurality of frames connecting the inner side surfaces of both cushion side frames F2. A pair of left and right ventilation openings S5 penetrating in the front-rear direction are formed in the seat back S2 at positions roughly corresponding to the occupant's shoulders.

[0033] 2, the seat back S2 has a seat back frame F3, a pad unit C1 that covers the front side of the seat back frame F3, and a back cover C2 that is provided behind the seat back frame F3. As shown in Fig. 2 and Fig. 3, the seat back frame F3 has a pair of opposing left and right back side frames 1L and 1R, a back upper frame 3 and a back lower frame 5 that connect the back side frames 1L and 1R, and a headrest frame 7 that is coupled to the back upper frame 3.

[0034] Each backside frame 1L, 1R is formed of a metal plate material so as to extend substantially vertically, and each has a U-shape facing inward in a horizontal cross-sectional view. The lower end of each backside frame 1L, 1R is rotatably connected to the rear end of each cushion side frame F2 via a reclining mechanism R. The reclining mechanism R selectively holds the tilt angle of each backside frame 1L, 1R relative to the cushion side frame F2 at any angle. The left backside frame 1L and the right backside frame 1R are arranged to be spaced apart in the left-right direction, forming the width of the seat back S2. A plate-shaped installation member 8 is provided between the left and right backside frames 1L, 1R. A predetermined elastic member 9 is hung between the left and right backside frames 1L, 1R to connect them, and the installation member 8 is connected to the left and right backside frames 1L, 1R via the elastic member 9. The installation member 8 can be displaced forward and backward with respect to the back side frames 1L, 1R by the elastic members 9, and supports the back of the occupant with elastic force. In this embodiment, the installation member 8 is formed using a plate-shaped member, but is not limited to a plate-shaped member and may be a known structure formed by a structure (e.g., a spring, etc.) that provides a lumbar support function.

[0035] The back upper frame 3 is formed of a metal pipe-like member having an inverted U-shape when viewed from the front. Both ends of the back upper frame 3 are joined by welding or the like to the upper parts of the inner surfaces of the corresponding back side frames 1L, 1R with some parts overlapping, and the back upper frame 3 connects the upper ends of both the back side frames 1L, 1R. The back lower frame 5 is also formed of a metal pipe-like member and extends in the left-right direction between the lower parts of both the back side frames 1L, 1R, and both left and right ends of the back lower frame 5 are joined to the inner surfaces of the back side frames 1L, 1R by welding or the like.

[0036] The headrest frame 7 has a first support part 50 which is joined to the upper rear surface of the back upper frame 3, and a second support part 52 and a third support part 54 which are joined to the upper front side of the first support part 50. The first support part 50 is formed of a pipe member which is inverted U-shaped in front view, and its lower end part is joined to the upper front surface of the back upper frame 3. The first support part 50 forms the shape of the headrest part S4 and also functions as a headrest pillar. The second support part 52 is formed to be approximately inverted U-shaped in front view and approximately L-shaped in side view, and its lower end part is joined to the first support part 50. The third support part 54 is also approximately inverted U-shaped in front view, and is formed to extend forward and upward in side view, and its lower end part is joined to the first support part 50. The first support part 50, the second support part 52, and the third support part 54 form the framework of the headrest part S4.

[0037] Furthermore, shoulder frames 6, which are metal pipe-shaped members for forming portions of the seat back S2 that come into contact with the shoulders of an occupant, are provided at both left and right ends of the upper portion of the back upper frame 3. One end of the shoulder frame 6 is joined by welding to the upper outer end of the back upper frame 3. The shoulder frame 6 extends upward from the one end, bends inward, and is fixed at the other end to the first support portion 50 by welding.

[0038] 3, a connecting member 10 is connected to the rear wall of the lower end of each of the left and right back side frames 1L, 1R by welding or the like. The connecting member 10 has a screw hole for connecting the back side frames 1L, 1R to the back cover C2.

[0039] Sub-side frames 30LU, 30RU are provided on the inside of the left and right back side frames 1L, 1R and on the outside of the installation member 8 in the left-right direction, connecting the back upper frame 3 to the left and right back side frames 1L, 1R. The sub-side frames 30LU, 30RU are both formed of bent metal linear members, and a pair of frame side locking portions 32 are provided on the left and right at predetermined positions in the up-down direction. In this embodiment, the frame side locking portions 32 are formed as parts of the sub-side frames 30LU, 30RU that extend linearly downward. Furthermore, below the left and right sub-side frames 30LU, 30RU, sub-side frames 30LD, 30RD are provided that are formed of metal linear members bent into an annular shape and have both ends connected to the left back side frames 1L, 1R. The sub-side frames 30LD, 30RD are also provided with frame side locking portions 32 in the same manner. All of the frame side locking portions 32 are disposed above the connecting member 10.

[0040] As shown in Figs. 2 and 4, the pad unit C1 has a pad 36, which is a cushioning material that connects the seat back frame F3 from the front, and a skin 37 that covers the front side of the pad 36. The skin 37 is a cloth-like member that is shaped to cover the front side of the pad 36, and has a skin opening 38 (first opening) that opens in a substantially rectangular shape at a position corresponding to the ventilation hole S5. The pad 36 is formed in a shape that covers the front side of the seat back frame F3, and has a pad opening 39 (third opening) that has a cross-sectional shape substantially the same as that of the skin opening 38 and penetrates from front to rear at a position corresponding to the ventilation hole S5. As shown in Fig. 8, a plurality of marks 37C are provided on the edge of the skin opening 38 of the skin 37 for positioning during assembly. In this embodiment, the marks 37C are formed by printing on the back side of the skin 37.

[0041] As shown in FIG. 4, a garnish 40 is attached to the vent S5. As shown in FIG. 5, the garnish 40 has a garnish opening 40H that is a hole that penetrates from the front to the rear and opens at both ends, and has a body 41 formed in a substantially rectangular tube shape and an extension portion 42 that extends in an annular shape in the radially outward direction from the front end edge of the body 41. The outer peripheral wall surface of the body 41 is defined by a first surface 41A facing upward and outward, a second surface 41B facing outward, a third surface 41C facing downward, and a fourth surface 41D facing inward. The garnish 40 further has a plurality of locking portions 43 that protrude from each wall surface on the outer peripheral wall surface (41A to 41D) of the body 41. The locking portions 43 are spaced rearward from the extension portion 42 and are arranged in a line along the extension portion 42. In this embodiment, three locking portions 43 are provided in a row on the first surface 41A at approximately equal intervals in the left-right direction, and two locking portions 43 are provided in a row on the third surface 41C in the left-right direction. Furthermore, three first surface locking claws 44A protruding in the radially outward direction (upward) of the body 41 are provided on the first surface 41A behind the respective locking portions 43. Similarly to the first surface 41A, two third surface locking claws 44C protruding in the radially outward direction (upward) of the body 41 are provided on the third surface 41C behind the respective locking portions 43. One fourth surface locking claw 44D is provided on the fourth surface 41D, which has a support extending rearward from the fourth surface 41D and a protrusion protruding outward from the outer peripheral wall surface from the rear end of the support.

[0042] Between two adjacent first surface locking claws 44A, a protrusion 45 is provided that protrudes upward and rearward from the first surface 41A. A protrusion 45 that protrudes downward and rearward from the third surface 41C is also provided on the fourth surface 41D side of the third surface locking claw 44C, similar to the first surface 41A. As shown in FIG. 4, the protrusion 45 provided on the first surface 41A protrudes radially outward from the first surface locking claw 44A, and the protrusion 45 provided on the third surface 41C protrudes radially outward from the third surface locking claw 44C. Therefore, when the garnish 40 is attached, the protrusions 45 each abut against the wall surface of the pad opening 39 at their radially outward protruding ends.

[0043] As shown in FIG. 4, a plate 46 is sandwiched between the extension portion 42 and the locking portion 43 of the garnish 40. The plate 46 is formed in a substantially rectangular plate shape, and a plate opening 47 (second opening) which is a through hole is formed in the substantially center thereof as shown in FIG. 6. Therefore, the plate 46 is substantially annular. The plate opening 47 is defined in a substantially rectangular shape by sides corresponding to the first surface 41A, the second surface 41B, the third surface 41C, and the fourth surface 41D which are the side surfaces of the garnish 40, and its outer periphery has substantially the same shape as the outer periphery of the body portion 41. The plate 46 is made of a resin which is more flexible than the garnish 40 and less flexible than the pad 36. The plate 46 further has a cut portion 48 which connects its outer periphery to the plate opening 47. Furthermore, a notch 47C recessed outwardly in a substantially rectangular shape is formed on the outer periphery of the plate opening 47 at a position corresponding to the protrusion 45 and the fourth surface locking claw 44D. Also, a notch 46C recessed inwardly in a wedge shape is formed on the outer periphery of the plate 46 at a position corresponding to the mark 37C formed on the skin 37.

[0044] As shown in Fig. 4 and Fig. 8, the plate 46 is disposed so that its front side surface abuts against the back surface of the skin 37, the skin opening 38 and the plate opening 47 overlap, and is sewn to the skin opening 38 of the skin 37. Therefore, as shown in Fig. 4, when the plate 46 is sandwiched between the extension portion 42 and the locking portion 43, the skin 37 is also sandwiched between the extension portion 42 and the locking portion 43 of the garnish 40. In addition, the extension portion 42 extends along the edge surface of the skin opening 38 of the skin 37, and covers the edge of the skin opening 38 from the surface. Therefore, around the periphery of the ventilation opening S5, the extension portion 42 of the garnish 40, the skin 37, the plate 46, and the pad 36 are disposed in the order described from the front.

[0045] 2, the back cover C2 is a resin plate-like member disposed along the rear surface of the seat back S2 and is formed symmetrically. The back cover C2 has a substantially rectangular base 60 and a head 61 extending upward from the upper edge of the base 60.

[0046] A pair of left and right connection parts 63 are formed on the upper part of the base 60, protruding forward from positions corresponding to the ventilation openings S5. As shown in FIG. 7, the connection parts 63 are formed with a connection part through hole 64 that opens at the front end, extends rearward from the front end, and reaches the rear surface of the back cover C2. Therefore, the connection parts 63 are cylindrical. The rear end of the connection part through hole 64 opens at an opening 62 formed on the rear surface of the back cover C2. As shown in FIG. 4, the body part 41 of the garnish 40 is inserted into the connection part through hole 64, whereby the garnish 40 and the connection parts 63 are joined together. At this time, the connection parts 63 are disposed between the body part 41 and the protruding part 45.

[0047] In order to prevent the garnish 40 from coming off the connecting portion 63, the connecting portion 63 has a plurality of engagement holes 66 formed along its front edge, penetrating the cylindrical wall. As shown in Fig. 8, when the garnish 40 and the connecting portion 63 are joined, the first surface locking claws 44A and the third surface locking claws 44C of the garnish 40 fit into the engagement holes 66, respectively. The engagement of the first surface locking claws 44A and the third surface locking claws 44C with the engagement holes 66 makes it difficult for the garnish 40 to come off the connecting portion 63.

[0048] Furthermore, an engagement portion 67 is formed on the outer peripheral surface of the connection portion 63 at a position corresponding to the fourth surface locking claw 44D when the body portion 41 of the garnish 40 is inserted into the connection portion through hole 64. As shown in FIG. 7, the engagement portion 67 has an engagement wall 67A that is a substantially rectangular plate-like shape and has a main surface that faces approximately in the front-rear direction and an engagement portion through hole 67B that penetrates the engagement wall 67A in the front-rear direction. When the body portion 41 of the garnish 40 is inserted into the connection portion through hole 64, the rear end of the fourth surface locking claw 44D abuts against the engagement wall 67A. When the garnish 40 is then moved rearward, the fourth surface locking claw 44D elastically deforms so that its rear end moves away from the outer peripheral surface of the connection portion 63, and the support post of the fourth surface locking claw 44D is inserted into the engagement portion through hole 67B. After the insertion, the fourth surface locking claw 44D is restored, and the protrusion of the fourth surface locking claw 44D is locked to the opening edge of the engagement portion through hole 67B. The protrusion of the fourth surface locking claw 44D is locked to the engagement portion through hole 67B, and the garnish 40 is connected to the connection portion 63. In this embodiment, in order to strengthen the connection between the garnish 40 and the connection portion 63, the upper and lower edges of the engagement wall 67A are connected to the wall surface of the connection portion 63 via a plate-shaped support member 67C, and the rigidity of the engagement wall 67A is increased. Two pairs of cover side locking portions 68 are provided on the upper portion of the back cover C2 and approximately in the center in the vertical direction. A predetermined locking claw is provided at the upper end of the head 61 to be connected to the headrest frame 7, and a predetermined locking claw is provided at the lower side of the connection portion 63 to be connected to the shoulder frame 6.

[0049] A through hole 72 penetrating the back cover C2 from front to rear is provided in the lower part of the base 60 of the back cover C2, below the cover side locking part 68, and at a position corresponding to the connecting member 10.

[0050] Next, a method of assembling the seat back S2 of the vehicle seat S will be described. As shown in FIG. 8, the plate 46 is placed in a position where the front surface of the plate 46 abuts against the rear surface of the skin 37 and where the skin opening 38 and the plate opening 47 overlap and align. At this time, the plate 46 may be positioned relative to the skin 37 by aligning the position of the notch 46C formed on the outer periphery of the plate 46 with the mark 37C provided on the edge of the skin opening 38. After positioning, the plate 46 and the skin 37 are sewn together over at least one circumference of the skin opening 38. A sewing machine is used for sewing, and when starting sewing, the sewing needle is moved along the cutting portion 48 to a position approximately midway between the plate opening 47 and the outer periphery of the plate 46. Then, the plate 46 and the skin 37 may be sewn together along a line (for example, the dashed line in FIG. 6) that traces approximately the midpoint between the outer periphery and the inner periphery of the plate 46.

[0051] Thereafter, the pad 36 having the pad opening 39 formed therein is prepared, the skin opening 38 is opposed to the pad opening 39, and the skin 37 is attached to the front surface of the pad 36. When the attachment is completed, the plate 46 is sandwiched between the skin 37 and the pad 36. The attachment may be performed using an adhesive or by providing hooks on the outer periphery of the skin 37 and hooking them onto a wire provided on the pad 36. Alternatively, the pad 36 may be formed by foaming polyurethane or the like, and at the same time, the pad 36 may be bonded to the skin 37.

[0052] After the skin 37 is joined to the front surface of the pad 36, the body 41 of the garnish 40 is inserted into the skin opening 38, the plate opening 47, and the pad opening 39. When inserting, the garnish 40 is first positioned so that the protrusion 45 and the fourth surface locking claw 44D face the notch 47C formed on the outer periphery of the plate opening 47. Then, the garnish 40 is inserted rearward from the skin opening 38, and the body 41 passes through the skin opening 38 and the plate opening 47, and is pushed in until it reaches the pad opening 39. The garnish 40 is further inserted rearward until the plate 46 is fitted between the extension 42 and the locking portion 43, completing the pad unit C1. At this time, as shown in FIG. 4, the front end of the connection portion 63 is sandwiched between the protrusion 45 and the first surface 41A, and the protrusion 45 cooperates with the first surface 41A to restrict the vertical movement of the connection portion 63.

[0053] Next, the back cover C2 is joined to the seat back frame F3. As shown in FIG. 2, the back cover C2 is positioned so that the base 60 is located behind the sub-side frames 30L and 30R and the head 61 is located behind the headrest frame 7. After that, the back cover C2 is moved forward of the seat back frame F3, and the connection portion 63 is passed between the shoulder frame 6 and the back upper frame 3. Furthermore, the back cover C2 is pressed against the seat back frame F3 from behind, and the cover side locking portion 68 is engaged with the frame side locking portion 32, and the locking claws provided on the base 60 and the head 61 are respectively joined to the headrest frame 7 and the shoulder frame 6. The cover side locking portion 68 is engaged with the frame side locking portion 32, and the locking claws provided on the back cover C2 are joined to the headrest frame 7 and the shoulder frame 6, whereby the back cover C2 is locked to the seat back frame F3. Thereafter, screws are passed through the through holes 72 and the back cover C2 is screwed to the connecting member 10, thereby fixing the back cover C2 to the seat back frame F3.

[0054] Then, the pad unit C1 is joined to the seat back frame F3. First, the pad unit C1 is placed in front of the seat back frame F3. Then, the pad unit C1 is moved backward, and the body 41 of the garnish 40 is inserted into the connection part through hole 64 of the connection part 63. At this time, as shown by the dashed line in FIG. 8, the first surface locking claw 44A and the third surface locking claw 44C of the garnish 40 are fitted into the corresponding engagement holes 66 of the connection part 63. At the same time, the fourth surface locking claw 44D is inserted into the engagement part through hole 67B of the engagement part 67, and the protrusion of the fourth surface locking claw 44D is hooked onto the edge of the engagement part through hole 67B. As a result, the pad unit C1 is fixed to the back cover C2 and joined to the seat back frame F3. Furthermore, the left and right edges of the pad unit C1 are placed so as to cover both the left and right ends of the seat back frame F3, thereby completing the seat back S2. 4, the garnish opening 40H communicates with the connection portion through-hole 64 of the connection portion 63 and opens at the opening 62 of the back cover C2. As a result, the seat back S2 is formed with a vent hole S5 penetrating from front to rear.

[0055] Next, the effects of the vehicle seat S will be described. The plate 46 is sandwiched between the extension portion 42 and the locking portion 43 of the garnish 40. Therefore, even if a pressing load is applied to the periphery of the skin opening 38, the relative position of the plate 46 with respect to the garnish 40 is unlikely to change. In addition, since the skin 37 is bonded to the plate 46, a gap is unlikely to occur between the skin 37 and the garnish 40.

[0056] In addition, the skin 37, the plate 46, and the pad 36 are arranged in the order described above from the front at the periphery of the skin opening 38. The plate 46 is made of a resin that is more flexible than the garnish 40 and less flexible than the pad 36. The pressing load applied to the periphery of the skin opening 38 is distributed over the entire plate 46. Therefore, local deformation of the pad 36 is unlikely to occur, and local gaps are unlikely to occur between the skin 37 and the garnish 40. Since gaps are unlikely to occur between the skin 37 and the garnish 40, the beauty of the periphery of the ventilation opening S5 is maintained. Furthermore, it is unlikely that an object will be caught in the gap between the extension portion 42 and the skin 37, or in the opening of the skin opening 38 and the pad opening 39. In addition, the end of the skin 37 is not exposed at the skin opening 38, and the skin 37 is unlikely to be damaged.

[0057] A plate-like plate 46 is sewn to the skin 37 along the edge of the skin opening 38. Therefore, compared to the case where a hole is provided in the skin 37 and the plate 46 is hooked to the hole, there is no need to form a hole to connect the plate 46 to the skin 37. Even if a tensile force is applied to the skin 37, there is no risk of cracks occurring from the hole.

[0058] In addition, the skin 37 and the plate 46 are sandwiched between the extension portion 42 and the locking portion 43. Therefore, even if a tensile force is applied to the skin 37, the plate 46 is unlikely to come off from between the extension portion 42 and the locking portion 43, and the end of the skin opening 38 will not be exposed. Since the locking portion 43 can be formed by providing a protrusion that protrudes from the body portion 41, the configuration of the locking portion 43 is simple.

[0059] The plate 46 has a cut portion 48 that connects the outer periphery and the plate opening 47. Therefore, the sewing needle can be moved along the cut portion 48 to a position roughly halfway between the plate opening 47 and the outer periphery of the plate 46, making it easier to start sewing. In addition, since the plate 46 is sewn to the skin 37 all around, the plate 46 is connected to holes provided at multiple locations on the skin 37 via a suture. Therefore, even if a tensile load is applied to the skin 37, the load is distributed to multiple locations, making it difficult for the skin to break. In addition, the plate 46 and the skin 37 can be firmly and easily connected by sewing.

[0060] 4, the connection portion 63 is formed in a cylindrical shape with openings at the front and rear ends. A garnish opening 40H that opens in the front and rear directions is formed in the body portion 41 of the garnish 40, and the body portion 41 is inserted from the front end of the connection portion 63. Therefore, the connection portion 63 and the body portion 41 are joined together, and the rigidity of the vehicle seat S is increased. Furthermore, by joining the connection portion 63 and the body portion 41, the garnish opening 40H and the connection portion through-hole 64 are communicated with each other, and a vent hole S5 that penetrates the seat back S2 in the front and rear directions can be formed.

[0061] Since the plate 46 is provided with the cutting portion 48, when the garnish 40 is inserted rearward from the skin opening 38, the cutting portion 48 opens, making it easy to pass the body 41 of the garnish 40 through the plate opening 47. In addition, since the plate 46 is more flexible than the garnish 40, the plate 46 is more easily deformed during assembly, making the assembly of the plate 46 easier.

[0062] The mark 37C formed on the edge of the skin opening 38 and the notch 46C formed on the outer periphery of the plate 46 allow the plate 46 to be easily positioned in a proper position relative to the skin 37. Also, the protrusion 45 formed on the outer periphery wall surface of the garnish 40 and the notch 47C formed on the inner periphery of the plate 46 allow the plate 46 to be easily positioned in a proper position relative to the garnish 40. The protrusion 45 can pass through the notch 47C, so the plate 46 can be easily joined to the garnish 40.

[0063] 4, the rear end of the garnish 40 is connected to the connection portion 63 of the back cover C2, and the back cover C2 is connected to the seat back frame F3. Therefore, the garnish 40 is unlikely to come off the pad 36 and is unlikely to shift from the correct position.

[0064] The connection portion 63 is disposed between the body portion 41 and the protruding portion 45. Therefore, when the body portion 41 is connected to the connection portion 63, the outward movement of the outer peripheral wall surface of the connection portion 63 is restricted by the protruding portion 45, and the inward movement of the outer peripheral wall surface is restricted by the body portion 41. Even if the connection portion 63 or the like is distorted due to a temperature change or an external impact, the connection portion 63 is pressed from the inside and outside, so that the distortion of the connection portion 63 is corrected during assembly. In addition, by correcting the distortion of the left and right connection portions 63, the distortion of the entire back cover C2 can also be corrected, and the design of the entire vehicle seat S can be improved.

[0065] Although the description of the specific embodiment is finished above, the present invention is not limited to the above embodiment and can be widely modified. In this embodiment, the plate 46 is sewn to the skin opening 38, but it is not limited to sewing and may be attached with an adhesive, double-sided tape, etc. The garnish 40 is made of resin, but it may be made of metal, wood, etc.

[0066] In this embodiment, the garnish 40 is configured to be unlikely to shift from the correct position by being coupled to the back cover C2 fixed to the seatback frame F3, but the present invention is not limited to this embodiment. For example, the rear end of the garnish 40 may be directly fixed to the seatback frame F3. The rear end of the garnish 40 may be coupled to a mounting member provided on the seatback frame F3. The garnish 40 may be inserted from both the front and back sides of the seatback frame F3, and the ends of the garnish 40 may be coupled to each other.

[0067] Moreover, the mark 37C is formed by printing on the back surface of the cover 37, but this is not limiting and the mark 37C may be formed in any visible manner, such as a protrusion provided on the cover 37.

[0068] The garnish 40 is used as a member forming the vent S5 formed in the seat back S2, but is not limited thereto and may be any member provided on the periphery of the skin opening 38 provided in the skin 37. The present invention can be applied, for example, to a belt guide provided on the periphery of a seat belt through hole provided in the seat cushion S1.

[0069] In this embodiment, a pair of left and right pad openings 39 are formed in the pad 36, and a pair of left and right garnishes 40 are fitted into the pad openings 39, but as shown in Fig. 9, a frame member 102 formed by joining the extensions 42 of the pair of left and right garnishes 40 of the above embodiment to each other via a joining portion 100 may be attached to the two pad openings 39. In this case, since the space between the two pad openings 39 is covered from the front by the joining portion 100, there is no need to cover the space between the two pad openings 39 with the skin 37, and the area of ​​the skin 37 can be reduced.

[0070] In addition, although the present invention has been described in the above embodiment as being applied to a vehicle seat, the present invention is not limited to being applied to a vehicle seat. For example, the present invention may be applied to a seat chair, a sofa, or the like. [Explanation of symbols]
