Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the technique described in Patent Document 1 above, it is necessary to engage the J-hooks while pulling the epidermis. Therefore, the operation of engaging the J-hooks is difficult and requires a great deal of time when the skill level of the operator is low. Thus, there is room for improvement in easily attaching the epidermis to the seat pad.

[0005] In consideration of the above facts, an object of the present invention is to obtain an epidermal attachment structure and an epidermal attachment method capable of easily attaching an epidermis to a seat pad.

Means for Solving the Problems

[0006] The surface attachment structure according to claim 1 comprises a base portion disposed on the inside of a vehicle seat and having an insertion hole formed therein; a first clip component fixed to the end of a first surface material covering a portion of the seat pad; a second clip component fixed to the end of a second surface material covering the other portion of the seat pad and configured to be engageable with the first clip component; and a clip inserted into the insertion hole from the outside of the seat and locked to the base portion, with the first clip component and the second clip component engaged with each other.

[0007] According to the present invention as described in claim 1, a portion of the seat pad is covered with a first surface material. The other portion of the seat pad is covered with a second surface material. A first clip component is fixed to the end of the first surface material, and a second clip component is fixed to the end of the second surface material.

[0008] When attaching the upholstery to the seat pad, first, the first and second upholstery materials are placed over the seat pad. Next, the first and second clip components engage with each other near the base to form a clip. Then, the clip, with the first and second clip components engaged, is inserted into the insertion hole in the base. This locks the clip into the base.

[0009] In this way, the first clip component and the second clip component are engaged, connecting the first and second surface materials, and the clip is inserted into the insertion hole. Therefore, before inserting the clip, the first and second surface materials can be easily connected at a position away from the seat pad. After inserting the clip, the first and second surface materials can be stretched along the seat pad.

[0010] The skin attachment structure according to claim 2 is the invention according to claim 1, wherein the clip comprises a first claw component formed on the first clip component and a second claw component formed on the second clip component, and is equipped with a claw that is locked into the insertion hole.

[0011] According to the present invention as described in claim 2, the clip is provided with a claw portion that engages with an insertion hole, and the claw portion is composed of a first claw portion formed on the first clip component and a second claw portion formed on the second clip component. Therefore, since the first clip component and the second clip component are each engaged with the insertion hole, the clip is stably engaged with the base portion compared to a structure in which only one of the first clip component or the second clip component is engaged.

[0012] The surface attachment structure according to claim 3 is the invention according to claim 2, wherein the insertion hole is formed through the base portion, the clip has the claw portion at its tip in the insertion direction, and the claw portion is locked to the inner edge of the insertion hole in the base portion.

[0013] According to the present invention as described in claim 3, the claw portion is locked to the inner edge of the hole in the insert hole, so the clip is locked to the base portion more stably.

[0014] The skin attachment structure according to claim 4 is the invention according to claim 2, wherein the clip has a gap between the first claw component and the second claw component.

[0015] According to the present invention as described in claim 4, when the clip is inserted into the insertion hole, the first clip component and the second clip component bend so that the first claw component and the second claw component are close to each other. As a result, the width of the claw portion is reduced, and the resistance when inserting the clip into the insertion hole is decreased.

[0016] The surface attachment structure according to claim 5 is the invention according to claim 1, wherein the clip has a flange portion that is locked to the outer edge of the insertion hole on the sheet side.

[0017] According to the present invention as described in claim 5, the clip is secured at the flange portion to the outer edge of the insertion hole on the sheet side. Therefore, it is possible to prevent the worker from pushing the clip too far when inserting it into the insertion hole.

[0018] The skin attachment structure according to claim 6 is the invention according to claim 5, wherein the insertion holes are formed in a plurality of the base portion, and the clip comprises a plurality of insertion portions inserted into the plurality of insertion holes, and a flange portion connecting the plurality of insertion portions.

[0019] According to the present invention as described in claim 6, an operator can grasp the flange portion and insert multiple insertion portions into multiple insertion holes at once. However, if the insertion hole is a single elongated hole, the center of the insertion hole tends to bulge, making it easy for the insertion portion to come out. In contrast, according to the present invention, since the insertion hole is divided into multiple sections, the dimension of each insertion hole in the direction along the sheet surface can be reduced. Therefore, bulging of the insertion hole can be suppressed, and the insertion portion can be made less likely to come out.

[0020] The skin attachment structure according to claim 7 is the skin attachment structure according to claim 1, wherein the end of the first skin material is fixed to the surface opposite to the surface facing the second clip component at the tip in the insertion direction of the first clip component, and the end of the second skin material is fixed to the surface opposite to the surface facing the first clip component at the tip in the insertion direction of the second clip component.

[0021] According to the present invention as described in claim 7, each end of the first and second skin material is fixed to the tip of the first and second clip component on the opposite side from the faces of each other and in the insertion direction. Therefore, when the clip is inserted into the insertion hole, the areas around each end of the first and second skin material are inserted deeply into the insertion hole together with the clip. This allows the first and second skin material to have excess length in the state before insertion, compared to the case where each end of the first and second skin material is fixed to the base end of the first and second clip component in the insertion direction, or where each end of the first and second skin material is provided on the faces of each other in the first and second clip component. Therefore, the first and second clip component can be easily engaged with the first and second skin material with excess length.

[0022] The surface attachment method according to claim 8 of the present invention comprises an engagement step of engaging a first clip component fixed to the end of a first surface material covering a portion of a seat pad with a second clip component fixed to the end of a second surface material covering the other portion of the seat pad to form a clip, and an insertion step of inserting the clip into an insertion hole formed in a base portion located on the inside of a vehicle seat and locking it to the base portion.

[0023] According to the present invention as described in claim 8, in the engagement step, a first clip component fixed to the end of the first surface material and a second clip component fixed to the end of the second surface material are engaged with each other. This constitutes the clip. In the insertion step, the clip is inserted into the insertion hole of the base portion. This locks the clip into the base portion.

[0024] According to the present invention, after engaging the first clip component and the second clip component to connect the first and second surface materials, the clips can be inserted into the insertion holes to stretch the first and second surface materials along the seat pad. [Effects of the Invention]

[0025] 2>As described above, the skin mounting structure according to the present invention described in claim 1 has an excellent effect that the skin can be easily attached to the seat pad while maintaining the appearance design of the sheet.

[0026] The skin mounting structure according to the present invention described in claim 2 has an excellent effect that the clip can be stably fastened to the base portion.

[0027] The skin mounting structure according to the present invention described in claim 3 has an excellent effect that the base portion can be easily formed and the clip can be more stably fastened to the base portion.

[0028] The skin mounting structure according to the present invention described in claim 4 has an excellent effect that the clip can be easily inserted into the insertion hole.

[0029] The skin mounting structure according to the present invention described in claim 5 has an excellent effect that the workability can be further improved.

[0030] The skin mounting structure according to the present invention described in claim 6 has an excellent effect that the clip can be more stably fastened to the base portion.

[0031] The skin mounting structure according to the present invention described in claim 7 has an excellent effect that the engagement between the first clip component and the second clip component can be made easier.

[0032] The skin mounting method according to the present invention described in claim 8 has an excellent effect that the skin can be easily attached to the seat pad while maintaining the appearance design of the sheet.

[Figure 7] This is an enlarged cross-sectional view of the main part corresponding to Figure 2, showing the skin attachment structure related to a modified example. [Modes for carrying out the invention]

[0034] The upholstery attachment structure 10 according to the first embodiment of the present invention will be described below with reference to Figures 1 to 6. The arrows FR, UP, LH, and RH shown in each figure as appropriate indicate the front side of the seat, the upper side of the seat, the left side in the seat width direction, and the right side in the seat width direction of the vehicle seat 12 equipped with a seat back 16 to which the upholstery attachment structure 10 is employed. Furthermore, when the directions front / back, up / down, and left / right are used in the following description without special specification, they refer to the front / back direction of the seat, the up / down direction of the seat, and the left / right direction of the seat width direction, respectively.

[0035] Figure 1 shows a rear perspective view of the vehicle seat 12. The vehicle seat 12 comprises a seat cushion 14 capable of supporting the buttocks and thighs of the seated occupant, and a seat back 16 capable of supporting the back of the seated occupant. The seat back 16 is tiltably connected to the rear end of the seat cushion 14 via a reclining mechanism 18.

[0036] The seat back 16 comprises a seat back frame (not shown) that constitutes the frame, a seat back pad 20 (see Figure 2) which is attached to the seat back frame as a seat pad, and a cover 22 that covers the seat back pad 20. The cover 22 is made of polyvinyl chloride as an example, but any material such as cloth, knit material, synthetic leather, and leather can be used.

[0037] The upholstery 22 is composed of a design surface trim 24 as a first upholstery material that covers the front, top, left and right sides, and upper back of the seat back 16, and a back trim 26 as a second upholstery material that covers the lower back of the seat back 16. The design surface trim 24 is formed three-dimensionally to conform to the shape of the front, top, left and right sides, and upper back of the seat back 16. On the other hand, the back trim 26 is formed in a substantially rectangular shape along the lower back of the seat back 16.

[0038] Furthermore, a seam 27 is provided in the center of the back trim 26 in the vertical direction of the seat, extending along the width direction of the seat. The upper end of a roughly rectangular skirt (not shown) is sewn to this seam 27. The skirt is positioned to cover the lower part of the seat back 16 and the upper part of the seat cushion 14. Note that the upholstery does not necessarily have to have a skirt.

[0039] Here, the design surface trim 24 and the back trim 26 are sewn together, so that the outer skin 22 is configured as a bag-like structure with the bottom open. In other words, the outer skin 22 has an opening 22A (see Figure 5) before being attached to the seat back pad 20 (see Figure 2), and the seat back pad 20 is inserted through this opening 22A to cover the seat back pad 20. Note that the method of joining the design surface trim 24 and the back trim 26 is not limited to sewing; they may also be joined by fasteners, for example.

[0040] Figure 2 shows a cross-sectional view taken along line 2-2 in Figure 1. The seat back pad 20 is made of a foamed resin, such as polyurethane foam. At the lower end of the seat back 16, a roughly rectangular parallelepiped base portion 28 is provided adjacent to the rear side of the lower end of the seat back pad 20. The base portion 28 is molded from a foamed resin that is harder than the seat back pad 20, such as lightweight and versatile foamed polypropylene. The base portion may be molded from a resin material other than foamed resin. Furthermore, the material of the base portion is not limited to resin, but may be other materials such as metal.

[0041] As shown in Figure 3, the base portion 28 extends along the width direction of the sheet. A recess 30 is formed on the lower surface of the base portion 28, which is recessed toward the upper side of the sheet. The recess 30 is formed in a substantially rectangular shape, with the sheet width direction as the longitudinal direction when viewed from the underside of the sheet.

[0042] Furthermore, the base portion 28 has three through-holes 32 formed therein, which serve as insertion holes that penetrate the sheet in the vertical direction. Each through-hole 32 is a roughly rectangular elongated hole with the sheet width direction as its longitudinal direction. The three through-holes 32 are formed at intervals in the sheet width direction and are each formed in the center of the base portion 28 in the front-to-back direction of the sheet. The outer ends of the through-holes 32 at both the left and right ends in the sheet width direction coincide with both ends of the recess 30 in the sheet width direction. Note that the number of insertion holes is not limited to three.

[0043] The base portion 28 is foam-molded in a base portion foam molding die (not shown). The seat back pad 20 is integrally molded with the base portion 28 by pouring a foaming agent into a pad foam molding die (not shown) with the base portion 28 set in it and allowing it to foam. Note that the method of joining the base portion and the seat pad is not limited to this; for example, the base portion may be fixed to the seat pad by adhesive or other methods. Alternatively, the seat pad and the base portion may be placed adjacent to each other by attaching them to the seat frame separately, without joining them.

[0044] As shown in Figure 2, a clip 34 is inserted into the through hole 32 of the base portion 28. The clip 34 is composed of a front resin member 36, which is a first clip component fixed to the lower end portion 24A of the design surface trim 24, and a rear resin member 38, which is a second clip component fixed to the lower end portion 26A of the back trim 26, which are engaged with each other. The front resin member 36 and the rear resin member 38 are made of resin such as polypropylene as an example, but are not limited to this and may be made of other materials.

[0045] The clip 34 is inserted from the underside of the sheet into the through hole 32 of the base portion 28, with the front resin member 36 and the rear resin member 38 engaged with each other. The clip 34 is composed of three insertion portions 40 inserted into each through hole 32, and a flange portion 42 that is locked in the recess 30 to the underside edge 32A of the through hole 32. A claw portion 44 is provided at the tip (upper end) of each insertion portion 40 in the insertion direction. The claw portion 44 is locked to the upper side edge 32B of the through hole 32. Note that the number of insertion portions is not limited to three, but can be appropriately provided according to the number of insertion holes.

[0046] As shown in Figure 4, the front resin member 36 comprises an elongated front flange 46 extending in the sheet width direction and three front insertion pieces 50 erected from the front flange 46. Similarly, the rear resin member 38 comprises an elongated rear flange 48 extending in the sheet width direction and three rear insertion pieces 52 erected from the rear flange 48. Each front insertion piece 50 and each rear insertion piece 52 has a continuous cross-sectional shape in the sheet width direction.

[0047] For example, the front resin member 36 and the rear resin member 38 are formed by extrusion molding and then cutting out the space between the front insertion piece 50 and the rear insertion piece 52, respectively. However, the first clip component and the second clip component may be formed by other methods, such as injection molding.

[0048] Each front insertion piece 50 of the front resin member 36 comprises a substantially rectangular plate-shaped front wall portion 50A erected upward from the rear end of the front flange 46 toward the seat, and a front claw portion 50B as a first claw portion component that is bent toward the front of the seat at the upper end of the front wall portion 50A. The front insertion piece 50 further comprises a pair of upper and lower front hooks 50C formed to protrude toward the rear and downward of the seat from the rear surface of the front wall portion 50A. The pair of upper and lower front hooks 50C are formed in a substantially L-shape that points downward when viewed in side cross-section.

[0049] Similarly, each rear insertion piece 52 of the rear resin member 38 includes a substantially rectangular plate-shaped rear wall portion 52A erected upward from the front end of the rear flange 48 toward the seat, and a rear claw portion 52B as a second claw portion component that is bent toward the rear of the seat at the upper end of the rear wall portion 52A. The rear insertion piece 52 further includes a pair of upper and lower rear hooks 52C formed to protrude toward the front and upper sides of the seat from the front surface of the rear wall portion 52A. The pair of upper and lower rear hooks 52C are formed in a substantially L-shape that faces upward in a side cross-section view so as to be able to engage with a pair of upper and lower front hooks 50C of the front resin member 36. Except for the upper and lower rear hooks 52C portions, the rear resin member 38 is formed symmetrically with the front resin member 36.

[0050] In this embodiment, the front hook 50C and the rear hook 52C, which are formed in a substantially L-shape in a side cross-sectional view, are described as engaging with each other. However, the first clip component and the second clip component may engage in other shapes and manners. Also, although the front insertion piece 50 and the rear insertion piece 52 are described as having a continuous cross-sectional shape, the embodiment is not limited to this. For example, the first clip component and the second clip component may be engaged by forming a concave shape on one part of the first clip component and a convex shape on the other part of the other.

[0051] As shown in Figure 2, the clip 34 is formed by the engagement of a pair of upper and lower front hooks 50C on the front resin member 36 and a pair of upper and lower rear hooks 52C on the rear resin member 38, thereby integrating the front resin member 36 and the rear resin member 38 into a single unit.

[0052] Furthermore, the lower end portion 24A of the design surface trim 24 is cut out, leaving portions corresponding to the three front insertion pieces 50. The front resin member 36 is sewn to the lower end portion 24A of the design surface trim 24 along the sheet width direction at each front insertion piece 50. Specifically, it is sewn to the design surface trim 24 on the sheet front side surface of the front wall portion 50A between the lower and upper front hooks 50C of the front claw portion 50B.

[0053] The lower end portion 26A of the rear trim 26 is cut out, leaving portions corresponding to the three rear insertion pieces 52. The rear resin member 38 is sewn to the lower end portion 26A of the rear trim 26 along the width direction of the seat at each rear insertion piece 52. Specifically, it is sewn to the rear trim 26 on the rear side of the rear wall portion 52A between the lower and upper rear hooks 52C of the rear claw portion 52B. Note that the front resin member 36 and the rear resin member 38 may be fixed to the design surface trim 24 and the rear trim 26, respectively, by methods other than sewing.

[0054] Here, the flange portion 42, which includes the front flange 46 and the rear flange 48, is formed to be slightly smaller than the recess 30 when viewed from the underside of the seat. As a result, the flange portion 42 is housed in the recess.

[0055] (Operation of this embodiment) Next, a method for attaching the cover 22 of the cover attachment structure 10 according to this embodiment to the seat back pad 20 will be described, and the operation of this embodiment will be explained through this description. Here, the process after the seat back pad 20, which is integrated with the base portion 28, is attached to a seat back frame (not shown), and the bag-shaped cover 22 is placed over the seat back pad 20 will be described.

[0056] (Engagement process) As shown in Figure 5, the upholstery 22 has an opening 22A at its lower end when placed over the seat back pad 20. The opening 22A is composed of the lower end 24A of the design surface trim 24 and the lower end 26A of the back trim 26.

[0057] As shown in Figure 6, during the engagement process, the front resin member 36 sewn to the lower end 24A of the design surface trim 24 and the rear resin member 38 sewn to the lower end 26A of the back trim 26 engage with each other. More specifically, the upper and lower pair of front hooks 50C of each front insertion piece 50 and the upper and lower pair of rear hooks 52C of each rear insertion piece 52 engage with each other. This forms a clip 34 and closes the opening 22A (see Figure 5). During the engagement process, the lower end 24A of the design surface trim 24 and the lower end 26A of the back trim 26 are bent.

[0058] (Insertion process) Furthermore, as shown in Figure 2, the clip 34 is inserted into the through hole 32 of the base portion 28. This causes the claw portion 44 to engage with the upper edge 32B of the through hole 32, and the flange portion 42 to engage with the lower edge 32A of the through hole 32. At this time, the lower end portion 24A of the design surface trim 24 and the lower end portion 26A of the back trim 26 enter the through hole 32 together with the clip 34, and are fixed in place by being sandwiched between the through hole 32 and the clip 34.

[0059] According to the surface attachment structure 10 and surface attachment method of this embodiment, the front resin member 36 and the rear resin member 38 are engaged to connect the lower end portion 24A of the design surface trim 24 and the lower end portion 26A of the back trim 26, after which the clip 34 is inserted into the through hole 32. Therefore, before inserting the clip 34, the design surface trim 24 and the back trim 26 can be easily connected at a position away from the seat back pad 20. Furthermore, after inserting the clip 34, the design surface trim 24 and the back trim 26 can be stretched along the seat back pad 20.

[0060] Furthermore, according to the skin attachment structure 10 and skin attachment method of this embodiment, the clip 34 is locked into the through hole 32 at the claw portion 44. Here, the claw portion 44 comprises a front claw portion 50B formed on the front resin member 36 and a rear claw portion 52B formed on the rear resin member 38. Therefore, since the front resin member 36 and the rear resin member 38 are locked into the through hole 32, the clip 34 is stably locked to the base portion 28.

[0061] Furthermore, according to the surface attachment structure 10 and surface attachment method of this embodiment, since the through hole 32 is formed to penetrate the base portion 28, the base portion 28 can be easily molded. In addition, since the claw portion 44 is locked to the upper edge portion 32B of the through hole 32 on the sheet side, the clip 34 is locked to the base portion 28 more stably.

[0062] Furthermore, according to the skin attachment structure 10 and skin attachment method of this embodiment, when the clip 34 is inserted through the through hole 32, the front resin member 36 and the rear resin member 38 bend so that the front claw portion 50B and the rear claw portion 52B are close to each other. As a result, the width of the claw portion 44 becomes narrower, and the resistance when inserting the clip 34 into the through hole 32 is reduced.

[0063] Furthermore, according to the surface attachment structure 10 and surface attachment method of this embodiment, the clip 34 is locked to the lower edge 32A of the through hole 32 at the flange portion 42. Therefore, it is possible to prevent the worker from pushing the clip 34 in too far when inserting it into the through hole 32.

[0064] Furthermore, according to the surface attachment structure 10 and surface attachment method of this embodiment, the worker can grasp the flange portion 42 and insert multiple insertion portions 40 into multiple through holes 32 at once. If the insertion hole were a single elongated hole, the center of the insertion hole would tend to bulge, making it easy for the insertion portion to come out. In contrast, according to the present invention, since the through hole 32 is divided into multiple portions, the dimension of each through hole 32 in the direction along the sheet surface can be reduced. Therefore, bulging of the through hole 32 can be suppressed, and the insertion portion 40 can be made less likely to come out.

[0065] Furthermore, according to the surface attachment structure 10 and surface attachment method of this embodiment, the design surface trim 24 and the back trim 26 are provided on the front resin member 36 and the rear resin member 38 at the ends opposite to each other's opposing surfaces and in the insertion direction. Therefore, when the clip 34 is inserted into the through hole 32, the area around the lower end 24A of the design surface trim 24 and the area around the lower end 26A of the back trim 26 are inserted deeply into the through hole 32 together with the clip 34. As a result, compared to the case where each end of the design surface trim and the back trim is fixed to the base end in the insertion direction of the front resin member and the rear resin member, respectively, or the case where the lower end 24A of the design surface trim 24 and the lower end 26A of the back trim 26 are fixed to opposing surfaces of the front resin member 36 and the rear resin member 38, respectively, the design surface trim 24 and the back trim 26 can be given excess length in their pre-insertion state. Therefore, the front resin member 36 and the rear resin member 38 can be easily engaged with the design surface trim 24 and the rear trim 26 while leaving excess length.

[0066] [Supplementary explanation of the above embodiment] In the above embodiment, the upholstery attachment structure 10 was described as being used in the seat back 16, but it is not limited to this. For example, the upholstery attachment structure may be used in the headrest or armrest.

[0067] Furthermore, in the above embodiment, the clip 34 was described as having a claw portion 44 comprising a front claw portion 50B formed on the front resin member 36 and a rear claw portion 52B formed on the rear resin member 38, which is engaged with the upper edge portion 32B of the through hole 32 on the sheet side, but the invention is not limited to this. For example, the clip may have a claw portion on only one of the first clip component and the second clip component.

[0068] Furthermore, although the above embodiment was described as having a through hole 32 in the base portion 28 that penetrates through the sheet in the vertical direction, the invention is not limited to this, and the insertion hole does not have to be formed through.

[0069] Furthermore, although the clip 34 has been described as having a claw portion 44 at its tip in the insertion direction, and the claw portion 44 is locked to the upper edge portion 32B of the through hole 32, it is not limited to this. For example, the modified structure shown in Figure 7 may be adopted. In the following modifications, components identical to those in this embodiment are denoted by the same reference numerals and their descriptions are omitted as appropriate.

[0070] (modified version) As shown in Figure 7, the modified skin attachment structure 60 is used on the seat back 62 and comprises a clip 68 which includes a base portion 28, a front resin member 64 sewn to the design surface trim 24, and a rear resin member 66 sewn to the back trim 26. Each front insertion piece 70 of the front resin member 64 comprises a front wall portion 70A, a front claw portion 70B, and a pair of upper and lower front hooks 70C. Each rear insertion piece 72 of the rear resin member 66 comprises a rear wall portion 72A, a rear claw portion 72B, and a pair of upper and lower rear hooks 72C.

[0071] Here, in the front wall portion 70A and the rear wall portion 72A, the upper front hook 70C and the rear hook 72C are provided at the tip in the insertion direction. The front claw portion 70B and the rear claw portion 72B are provided between the upper and lower pair of front hooks 70C and the upper and lower pair of rear hooks 72C in the front resin member 64 and the rear resin member 66, respectively. In Figure 7, the solid line represents the state before the clip 68 is inserted through the through hole 32, and the dashed line represents the state after the clip 68 is inserted through the through hole 32 and the skin 22 is attached.

[0072] According to the modified skin attachment structure 60, the claw portion 74, which is composed of the front claw portion 70B and the rear claw portion 72B, bites into and locks into the base portion 28 at the vertical center of the through hole 32.

[0073] Furthermore, according to the modified surface attachment structure 60, since the tip of the clip 68 is engaged with the upper front hook 70C and the upper rear hook 72C, even if the lower end 24A of the design surface trim 24 is pulled towards the front of the seat and the lower end 26A of the back trim 26 is pulled towards the rear of the seat before the clip 68 is inserted, it is possible to prevent the tips of the front resin member 64 and the rear resin member 66 from separating and the tip of the clip 68 from opening. Therefore, insertion of the clip 68 into the through hole 32 can be made even easier. Note that the clip 68 may be inserted into an insertion hole that is not a through hole, not just the through hole 32. Even in this case, the claw portion 74 is locked into the insertion hole, so the surface 22 can be attached to the seat back pad 20.
