Description

[Technical field]

[0001] The present invention relates to a vehicle seat structure. [Background technology]

[0002] Vehicles are sometimes equipped with a seat belt reminder function that uses a detection device to detect whether the vehicle's seat belt is fastened or undone, and alerts the occupant in the vehicle seat with an alarm or other means if they are not fastening their seat belt.

[0003] For example, in Patent Document 1, the above-mentioned detection is performed by transmitting a signal from a buckle switch installed in a lap-side buckle to an ECU (Electronic Control Unit) via a wire harness.

[0004] On the other hand, in order to secure a large space behind the front seat, there is a technique for moving the position of the seat cushion forward and downward when the seat back of the rear seat is tilted forward. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2011-126358 A Summary of the Invention [Problem to be solved by the invention]

[0006] When a buckle to which a cord-like object such as a wire harness for detecting fastening or unfastening of a seat belt is connected is provided on a seat cushion that moves as described above, the following problem occurs: The wire harness may come into contact with surrounding members as the seat cushion moves, resulting in damage or deterioration.

[0007] In addition, the buckle on the seat cushion is naturally displaced as the seat cushion moves, and there is a possibility that the buckle may move from its fixed position on the seat cushion, resulting in an unexpected displacement of the buckle. In such a case, the wire harness or other cord-like member may come into contact with surrounding members and be damaged, or may be deteriorated due to localized stress concentration on the cord-like member.

[0008] In view of such problems, the present invention aims to provide a vehicle seat structure that can more fully protect a cord-like body routed from a buckle provided on a seat cushion that moves forward and downward when the seat back is tilted forward. [Means for solving the problem]

[0009] In order to solve the above problems, a typical configuration of the present invention is a vehicle seat structure comprising a seat having a seat portion on which a vehicle occupant sits and a seat back that stands up from the rear end of the seat portion and serves as a backrest for the occupant, a moving mechanism that tilts the seat back forward and moves the seat portion forward and downward, and a buckle that is located on the side of the seat portion and to which the tongue of the occupant's seat belt is attached, the vehicle seat structure further comprising a cord-like body that is arranged from the buckle to the floor panel, and a flexible guide portion that extends adjacent to the cord-like body from the buckle to the floor panel and guides the path of the cord-like body.

[0010] In order to solve the above problems, another representative configuration of the present invention includes a seat having a seat portion on which a vehicle occupant sits and a seat back that stands up from the rear end of the seat portion and serves as a backrest for the occupant, a moving mechanism that tilts the seat back forward and moves the seat portion forward and downward, a buckle that is located on the side of the seat portion and to which the tongue of the occupant's seat belt is attached, and the vehicle seat structure further includes a cord-like body that is routed from the buckle toward a floor panel, the vehicle seat structure further comprising a restraining portion that is a belt-like flexible member that covers the buckle from front to rear and is fixed to the side of the seat portion at the front and rear of the buckle, thereby restraining the buckle to the side of the seat portion. Effect of the Invention

[0011] According to the present invention, it is possible to provide a vehicle seat structure that can more completely protect a cord-like body routed from a buckle provided on the seat portion, which moves forward and downward when the seat back is tilted forward.

[0013] One embodiment of the present invention is a vehicle seat structure comprising a seat having a seat portion on which a vehicle occupant sits and a seat back that stands up from the rear end of the seat portion and serves as a backrest for the occupant, a moving mechanism that tilts the seat back forward and moves the seat portion forward and downward, and a buckle that is disposed on the side of the seat portion and to which the tongue of the occupant's seat belt is attached, the vehicle seat structure being characterized in that it further comprises a cord-like body that is routed from the buckle to a floor panel, and a flexible guide portion that extends adjacent to the cord-like body from the buckle to the floor panel and guides the path of the cord-like body.

[0014] According to the present invention, by locating a flexible guide portion adjacent to the cord-like body from the buckle to the floor panel, it is possible to prevent the cord-like body from coming into contact with surrounding members and being deteriorated when the seat portion moves.

[0015] When the moving mechanism moves the seat portion forward and downward, at least a portion of the guide portion may be adjacent to the underside of the cord-like body.

[0016] With this configuration, when the seat portion moves forward and downward, the cord-like body can be prevented from coming into contact with, and being deteriorated by, the floor panel located below it.

[0017] The guide portion may be formed of a band-like member that is wider than the cord-like body. If the guide portion is a band-like member, it is easily deformed in response to the movement of the seat portion, and the range over which the cord-like body is covered is increased, thereby improving the effect of protecting the cord-like body.

[0018] The vehicle seat structure further includes a vehicle body fixing portion that fixes the guide portion to the floor panel at a position away from the buckle in the fore-and-aft direction, and the guide portion has a width along the vehicle width direction from the floor panel to a predetermined position just before the buckle, and twists from that position to have a width along the vehicle fore-and-aft direction when it reaches the buckle.

[0019] The reason for this configuration is that the belt-shaped guide part needs to be twisted midway. That is, in the vicinity of the floor panel, the guide part needs to be in a horizontal position with a width along the vehicle width direction in order to be adjacent to the underside of the rope-like body and protect the rope-like body from the floor panel, particularly when the seat part moves forward and downward. On the other hand, when the guide part is connected to the buckle, the guide part needs to be in a position with a width along the vehicle front-rear direction, that is, parallel to the side surface of the seat part, so that the guide part needs to be twisted at the above-mentioned predetermined position.

[0020] The vehicle body fixing portion may have an engagement portion with which the guide portion engages, and the engagement portion may extend obliquely from the floor panel side toward the buckle side.

[0021] According to this configuration, since the engaging portion is inclined, even if the seat portion moves forward and downward, the guide portion is floating above the floor panel, and the cord-like body is therefore kept floating above the floor panel and more completely protected.

[0022] Furthermore, since the engaging portion is inclined, the guide portion does not bend significantly before and after the movement of the seat portion, and the displacement of the cord-like body can also be suppressed.

[0023] The cord-like body may be adjacent to the vehicle body fixing portion side of the guide portion having a width along the vehicle front-rear direction when it reaches the buckle.

[0024] According to this configuration, the length of the cord-like body can be shortened while preventing the upper part of the cord-like body from coming into contact with the surroundings.

[0025] Another embodiment of the present invention is a vehicle seat structure comprising a seat having a seat portion on which a vehicle occupant sits and a seat back that stands up from the rear end of the seat portion and serves as a backrest for the occupant, a moving mechanism that tilts the seat back forward and moves the seat portion forward and downward, a buckle that is located on the side of the seat portion and to which a tongue of a seat belt for the occupant is attached, and a cord-like body that is routed from the buckle toward a floor panel, the vehicle seat structure further comprising a restraining portion that is a belt-like flexible member that covers the buckle from front to rear and is fixed to the side of the seat portion at the front and rear of the buckle, thereby restraining the buckle to the side of the seat portion.

[0026] According to the present invention, the restraining portion prevents the buckle from being accidentally displaced from its fixed position on the side surface of the seat, thereby more completely protecting the cord-like body.

[0027] The vehicle seat structure may further include a recess formed in a side surface of the seat portion, and the buckle may be restrained by the restraint portion while being inserted into the recess. With this configuration, the recess can further restrict the displacement of the buckle.

[0028] A seat frame member constituting the seat portion may be disposed below the buckle. With this configuration, the buckle can be supported by the seat frame member having a high rigidity, and the displacement of the cord-like body can be suppressed by limiting the displacement of the buckle in the up-down direction.

[0029] By arranging the seat frame member so as to be recessed below the side surface of the seat portion, a passage for the cord-like body routed from the buckle is preferably formed between the seat frame member and the side surface of the seat portion.

[0030] According to this configuration, the cord-like body can be pulled downward from the lower part of the buckle, thereby maintaining the effect of the seat frame member of suppressing displacement of the cord-like body by limiting the displacement of the buckle in the vertical direction, and further suppressing deformation and displacement of the cord-like body, thereby suppressing deterioration of the cord-like body.

[0031] The buckle is restrained by the restraining part with a part of it protruding above the seat surface of the seat, and when the seat back is tilted forward to the maximum extent by the moving mechanism, it comes into contact with the buckle or is spaced a predetermined distance from the buckle.

[0032] According to this configuration, by protruding the buckle, it is possible to easily fasten the tongue of the seat belt to the buckle, and also to prevent the buckle from being displaced downward when the seat back is tilted forward. EXAMPLES

[0033] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0034] Fig. 1 is a perspective view showing an embodiment of a vehicle seat structure according to the present invention. In Fig. 1 and all other drawings, the front-rear direction of the vehicle is indicated by arrows F (Forward) and B (Backward), the left and right directions in the vehicle width direction are indicated by arrows L (Leftward) and R (Rightward), and the up-down direction is indicated by arrows U (Upward) and D (Downward).

[0035] (Vehicle seats) As shown in Fig. 1, an embodiment of the present invention will be described using the rearmost seats 100, 102 of a three-row seating arrangement. The front two rows of seats are not shown in Fig. 1. Since the structures of the seats 100, 102 are substantially symmetrical, the present embodiment will be described hereinafter using the seat 100 as a representative unless otherwise specified. The seat 100 is placed on a floor panel 104 and has a seat portion 106 on which a vehicle occupant sits and a seat back 108 that stands upright from the rear end of the seat portion 106 and serves as a backrest for the occupant.

[0036] The seat 100 is actually covered with a seat cover 109 made of leather or cloth, but the seat cover 109 is not shown in the figures except in FIG. 4 described later.

[0037] (moving mechanism) Fig. 2 is a side view showing the states before and after the seat back 108 of the seat 100 in Fig. 1 is tilted forward. As indicated by arrow 110 in Fig. 2, the right and left views respectively show the states before and after the seat back 108 is tilted forward. The movement mechanism 112 that tilts the seat back 108 forward is a link mechanism having four links (rods) shown imaginarily by dashed and dotted lines.

[0038] The movement mechanism 112 has four joints 112a, 112b, 112c, and 112d that serve as rotation starting points, and two of these, the joints 112a and 112b, do not change their positions in the front-rear direction when the seat back 108 tilts forward. On the other hand, when the seat back 108 tilts forward, as shown in the left figure, the joint 112c that is integral with the seat portion 106 moves forward and downward. In this way, when the seat back 108 tilts forward, the seat portion 106 moves forward and downward.

[0039] Fig. 3 is a perspective view and a partially enlarged view of the seat 100 in Fig. 1. As shown in the partially enlarged view, a recess 114 recessed in the vehicle width direction is formed on the side of the seat portion 106. This recess 114 is made of resin and is fitted into the seat portion 106. A buckle 120 is inserted into the recess 114, as shown in the overall view of the seat 100 on the left side of Fig. 3. Note that in the partially enlarged view on the right side of Fig. 3, the buckle 120 is omitted for convenience of illustrating the recess 114. The buckle 120 is a device for restraining an occupant with a seat belt by fastening a tongue (not shown) of the occupant's seat belt.

[0040] Since the buckle 120 is inserted into the recess 114 provided on the side of the seat portion 106 as shown in FIG. 3, when the seat portion 106 moves forward and downward as shown in FIG. 2, the buckle 120 also moves forward and downward.

[0041] (Wire harness) Fig. 4 is a perspective view and a partially enlarged view of the seat 100 in a state in which the seat portion 106 has moved forward and downward, as shown in the left diagram in Fig. 2. Unlike the other diagrams, Fig. 4 shows the seat 100 in a state in which it is covered with a seat cover 109 made of leather or cloth. In other words, the seat portion 106 and the seat back 108 are covered with the seat cover 109. In particular, the seat portion 106 is covered with the seat cover 109, including the recess 114 provided on the side surface thereof.

[0042] As shown in Figs. 2 to 4, a wire harness 122, which is a cord-like body, is routed from the buckle 120 toward the floor panel 104. The wire harness 122 is a transmission wiring that transmits a signal that detects whether the seat belt is fastened or detached. However, the wire harness 122 is not limited to such a transmission wiring, and may be, for example, a power transmission wiring that supplies power to an electric locking mechanism that automatically locks the tongue attached to the buckle 120. Furthermore, the present embodiment is not limited to a cord-like body such as the wire harness 122, and may be applied to, for example, a cylindrical member such as a flow passage member (tube) for blowing a fluid (air / conditioned air) to the seat portion 106, or a string-like member.

[0043] 2 to 4, a guide portion 124 is provided extending adjacent to the wire harness 122 from the buckle 120 to the floor panel 104. The guide portion 124 is a flexible member that guides the path of the wire harness 122. The guide portion 124 is a strip-shaped member and has a width wider than the wire harness.

[0044] Fig. 5 is a cross-sectional view taken along line AA of the seat 100 in Fig. 4. As shown in Fig. 4 and Fig. 5, the buckle 120, the wire harness 122, and the guide portion 124 are integrally bound together by a binding portion 126 that surrounds and covers them.

[0045] (Restraint part) As shown in Figures 4 and 5, the buckle 120 bound by the binding portion 126 is restrained by a belt-like flexible restraining portion 130 that covers the front and rear of the buckle 120. This restraining portion 130 is fixed to the side of the seat cushion in front of and behind the buckle 120. More specifically, the restraining portion 130 is actually fixed to a seat cover 109 (Figure 4; not shown in Figure 5) made of leather or the like that covers the seat portion 106. In this way, the restraining portion 130 restrains the buckle 120 to the side of the seat portion 106.

[0046] As already mentioned, the buckle 120 moves forward and downward in accordance with the forward and downward movement of the seat portion 106 shown in Fig. 2. However, if the buckle 120 is unexpectedly displaced from its fixed position on the side of the seat portion 106, the wire harness 122 may also be pulled in an unexpected direction and come into contact with surrounding members, resulting in damage or deterioration. Therefore, in this embodiment, the buckle 120 is restrained by the restraining portion 130, which restricts the buckle 120 from moving from its fixed position on the side of the seat portion 106, thereby more thoroughly protecting the wire harness 122.

[0047] (recess) 4 and 5, the buckle 120 is restrained by the restraining portion 130 while being inserted into the recess 114. In this embodiment, the recess 114 can further restrict the displacement of the buckle 120 in the front-rear direction.

[0048] If the restraining portion 130 can sufficiently restrain the buckle 120 to the side surface of the seat portion 106, the recess 114 is not essential. Conversely, if the recess 114 can sufficiently hold the buckle 120 to the side surface of the seat portion 106, the restraining portion 130 is not essential.

[0049] In this embodiment, the buckle 120 is accommodated in the recess 114 so as not to protrude in the vehicle width direction from the side surface of the seat portion 106. However, the vehicle width direction dimension of the buckle accommodating space in the recess 114 may be made smaller than that of the buckle 120 so that the buckle 120 protrudes in the vehicle width direction from the side surface of the seat portion 106. In that case, the buckle 120 may be accommodated in the recess 114 by pressing down the buckle 120 with the restraint portion 130 to elastically deform the wall surface that forms the recess 114.

[0050] Fig. 6 is a perspective view showing the internal structure of the seat 100 in Fig. 3. Fig. 6(a) is an external view of the seat 100, Fig. 6(b) is a view of the internal structure with the seat cushion 106A removed from the sitting portion 106 of the seat 100 in Fig. 6(a) and the seat back cushion 108A removed from the seat back 108, and Fig. 6(c) is a view of the internal structure with the frame cover 132 in Fig. 6(b) further removed.

[0051] The seat portion 106 has a seat cushion 106A covered with a seat cover 109 (see FIG. 4; not shown in FIG. 6) and a seat pipe 136 that supports the seat cushion 106A. The seat back 108 has a seat back cushion 108A covered with the seat cover 109 and a seat back pipe 108B that supports the seat back cushion 108A.

[0052] (Seat frame parts) 6(b) and (c), the frame cover 132 covers a seat frame 134 that extends from the seat back 108 to the seat 106. The seat frame 134 covers a seat pipe 136, and both are framework members that constitute the seat 100. The seat frame 134 has a lower portion joined to the seat pipe 136, and an upper portion supported rotatably by the seat back pipe 108B. In this way, the seat frame 134 constitutes a joint 112b that is a part of the movement mechanism 112.

[0053] As shown in FIG. 3, the frame cover 132 and the seat frame 134 are located in the lower half of the recess 114 and are recessed to the right side of the vehicle based on the side of the seat 106, but not as far to the right as the recess 114.

[0054] 5, the seat framework members constituting the seat 106, i.e., the seat frame 134 and the seat pipe 136, are disposed below the buckle 120. With this configuration, the buckle 120 can be supported by the rigid seat frame 134 and the seat pipe 136 (seat framework members), and by limiting the displacement of the buckle 120 in the up-down direction, the displacement of the wire harness 122 can be suppressed.

[0055] 5, the seat frame 134 and the seat pipe 136 (seat framework member) are disposed to be recessed to the right of the vehicle from the side surface of the seat 106. As a result, a passage 138 for the wire harness 122 routed from the buckle 120 is formed between the seat frame 134 and the seat pipe 136 and the side surface of the seat 106.

[0056] 5, the wire harness 122 can be pulled out downward from the lower part of the buckle 120. Therefore, it is possible to maintain the effect of the seat frame 134 and the seat pipe 136 (seat framework member) of suppressing the displacement of the wire harness 122 by limiting the displacement of the buckle 120 in the up-down direction. Furthermore, it is possible to suppress the deformation and displacement of the wire harness 122, and thus the deterioration of the wire harness 122.

[0057] (The positional relationship between the upward protruding buckle and the seat back) 5, the buckle 120 is restrained by the restraint portion 130 in a state in which a part of the buckle 120 protrudes above the seat surface 106B of the seat portion 106. On the other hand, when the seat back 108 is tilted forward to the maximum extent by the movement mechanism 112, the seat back 108 maintains a predetermined distance α from the buckle 120.

[0058] According to this configuration, the buckle 120 protrudes upward from the seat surface 106B of the seat portion 106, making it easier to fasten the tongue of the seat belt to the buckle 120. At the same time, by maintaining the gap α, the buckle 120 is prevented from displacing downward when the seat back 108 is tilted forward. Note that it is not essential to provide the gap α, and the seat back 108 may just abut against the buckle 120.

[0059] (Guide part) Fig. 7 is a perspective view showing the guide portion 124 corresponding to the states before and after the seat portion 106 in Fig. 2 moves forward and downward. Unlike Fig. 2, Fig. 7 shows the guide portion 124 as seen from the left rear side of the vehicle. Figs. 7(a) and (b) respectively correspond to the states before and after the seat portion 106 moves forward and downward as shown in Fig. 2. Fig. 7(c) is a BB end view of the guide portion 124 and wire harness 122 in Fig. 7(a).

[0060] As shown in FIG. 7, the guide portion 124 is fixed to the floor panel 104 by a vehicle body fixing portion 140.

[0061] 7, according to this embodiment, a flexible guide portion 124 is provided adjacent to the wire harness 122 from the buckle 120 to the floor panel 104. This makes it possible to prevent the wire harness 122 from coming into contact with surrounding components and being deteriorated when the seat portion 106 moves.

[0062] In particular, a portion 122A of the wire harness 122 excluding the portion directly below the buckle 120 and the portion subsequent to the vehicle body fixing portion 140 for the guide portion 124 extends upright as shown in FIG. 7(a) before the seat portion 106 moves forward and downward, but assumes a nearly horizontal position as shown in FIG. 7(b) after the seat portion 106 moves.

[0063] Then, part 124A of guide portion 124 is adjacent to the underside of part 122A of wire harness 122 that is in this nearly horizontal position. In this way, when part 122A of wire harness 122, which has the greatest displacement, is closest to floor panel 104, guide portion 124 is adjacent to the underside thereof, thereby preventing wire harness 122 from contacting and deteriorating floor panel 104 located below.

[0064] In addition, since the guide portion 124 is a belt-shaped member, it is easily deformed in response to the movement of the seat portion 106, and further, the range over which the wire harness 122 is covered is large, so that the effect of protecting the wire harness 122 is high.

[0065] 2 and 7, the vehicle body fixing portion 140 fixes the guide portion 124 to the floor panel 104 at a position away from the buckle 120 toward the rear of the vehicle. The guide portion 124 has a width along the vehicle width direction from the floor panel 104 to a position 124B or 124C in front of the buckle 120, and is twisted from the position 124B or 124C so that it has a width along the vehicle front-rear direction when it reaches the buckle 120. The position that is the starting point of this twisting changes slightly before and after the seat portion 106 moves forward and downward, such as to the position 124B or the position 124C.

[0066] The belt-shaped guide portion is twisted in this manner because it is necessary. That is, in the vicinity of the floor panel 104, especially after the seat portion 106 moves forward and downward, the guide portion 124 is adjacent to the underside of the wire harness 122 to protect the wire harness 122 from the floor panel 104. Therefore, the guide portion 124 needs to be in a horizontal position having a width along the vehicle width direction. On the other hand, when the guide portion 124 is connected to the buckle 120, the guide portion 124 needs to be in a position having a width along the vehicle front-rear direction, that is, parallel to the side surface of the seat portion 106, so that the guide portion 124 needs to be twisted at the above-mentioned position 124B or 124C.

[0067] (Vehicle body fixing part and engagement part) 7, the vehicle body fixing portion 140 has an engagement portion 140A that engages with the guide portion 124. The engagement portion 140A extends at an angle from the floor panel 104 side toward the buckle 120 side so as to rise toward the front of the vehicle.

[0068] Since the engaging portion 140A is inclined in this manner, as shown in Fig. 7(b), even if the seat portion 106 moves forward and downward, the guide portion 124 is raised above the floor panel 104. Therefore, the wire harness 122 is kept raised above the floor panel 104 and is more completely protected.

[0069] Furthermore, since the engaging portion 140A is inclined, the guide portion 124 does not bend significantly before and after the movement of the seat portion 106 shown in FIG. 7(a), and the displacement of the wire harness 122 can also be suppressed.

[0070] Fig. 8 is a plan view of the wire harness 122 and the guide portion 124 of Fig. 7(a) viewed from above. Fig. 9 is a perspective view of the wire harness 122 and the guide portion 124 of Fig. 8 viewed from a different direction. Figs. 8 and 9 also show the buckle 150, wire harness 152, and guide portion 154 for the seat 102 of Fig. 1, but as their configurations are similar to those for the seat 100, their description will be omitted.

[0071] As shown in Fig. 7(c), when the wire harness 122 reaches the buckle 120, it is adjacent to the vehicle body fixing part 140 side of the guide part 124 having a width along the vehicle front-rear direction, that is, the rear side in this embodiment. This is true not only before the seat part 106 moves in Fig. 7(a) but also after the seat part 106 moves in Fig. 7(b).

[0072] According to this configuration, the length of the wire harness 122 can be shortened, while preventing the upper part of the wire harness 122, which is protected by the upper part of the guide portion 124 having a width along the vehicle front-rear direction, from coming into contact with surrounding components.

[0073] 8 and 9, the wire harness 122 is also pulled rearward by the seat support bracket 160 and fixed to the floor panel 104, so it does not sag in front of the guide portion 124. In addition, the seat support bracket 160 keeps the wire harness 122 floating above the floor panel 104, preventing it from coming into contact with the floor panel 104. In this respect as well, the wire harness 122 is protected.

[0074] 8 and 9, a support member 162 that supports the seat 102 is fixed to the floor panel 104 via a seat support bracket 160. An upper portion of the support member 162 constitutes a joint 112b that is a part of the movement mechanism 112.

[0075] A harness support bracket (cord-like body support bracket) 164 for supporting the wire harness 122 is provided on the outer side of the support member 162 and the seat support bracket 160 in the vehicle width direction.

[0076] The wire harness 122 is supported by the front surface of the harness support bracket 164, which supports the harness 122 forward of a wire harness support point 160A of the seat support bracket 160 when viewed from above, as shown in FIG.

[0077] With this configuration, when the seat portion 106 is moved forward and downward from the initial position, the seat support bracket 160 and the harness support bracket 164 can suppress the displacement of the wire harness 122 on the floor panel 104 side. In addition, the wire harness 122 can be prevented from contacting vehicle components, luggage, and the like arranged behind the seat portion 106.

[0078] Moreover, the wire harness support point 160A of the seat support bracket 160 and the support point 164A of the harness support bracket 164 are set at a position higher than the floor panel 104. Therefore, at least a portion of the wire harness 122 can be raised above the floor panel 104, and contact and sliding between the wire harness 122 and the floor panel 104 can be suppressed.

[0079] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the above-described embodiment. It is clear that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

[0080] Furthermore, the present invention can be implemented by freely combining the inventions described in the claims and examples, regardless of the dependent relationships of the claims. [Industrial Applicability]
