Summary of the Invention

Problems to be Solved by the Invention

[0005] In the above prior art, since the hole covering portion is configured to be pushed into the inside of the hole of the pad through hole by the insertion of the locking portion, sagging is likely to occur. When the hole covering portion sags, the frame structure on the hole inner side from the pad through hole may be exposed, and the appearance of the seat may be impaired. Therefore, the present invention provides a seat cover capable of appropriately suppressing the exposure of the frame structure on the hole inner side from the pad through hole of a seat pad through which a lower anchor of the ISO-FIX system is passed.

Means for Solving the Problems

[0006] As means for solving the above problems, the seat cover of the present invention takes the following means.

[0007] That is, a first invention of the present invention is a seat cover to be placed on a seat pad having a pad through hole through which a lower anchor of the ISO-FIX system is passed, the seat cover including a top plate cover portion that covers a top plate portion of the seat pad excluding the pad through hole, a cylindrical cover portion that extends from the top plate cover portion so as to cover an inner peripheral surface of the pad through hole in a cylindrical shape along the inner peripheral surface of the hole, and a bottom cover portion that extends from the cylindrical cover portion so as to close a cylindrical opening on the bottom side of the cylinder and includes a slit-shaped anchor passing hole through which the lower anchor can be passed into the cylinder.

[0008] According to the first invention, by passing the lower anchor through the anchor passing hole of the bottom cover portion, the lower anchor can be passed through the pad through hole so that it can be visually recognized from the outside. In addition, the inside of the hole of the pad through hole can be covered by the bottom cover portion so that the frame structure on the hole inner side is not exposed.

[0009] A second invention of the present invention is a seat cover further having a drawing portion that draws the cylindrical cover portion and / or the bottom cover portion toward the back side of the pad in the first invention.

[0010] According to the second invention, it is possible to appropriately suppress the cylindrical cover portion and the bottom cover portion from rising from the pad through hole to the front side of the pad.

[0011] The third invention of the present invention is the second invention described above, wherein the anchor through-hole is in the shape of a slit extending longitudinally in the sheet width direction, and the drawing-in part is a sheet cover that draws the bottom cover part of the cylinder inward toward the back side of the pad so as to pull both sides of the bottom cover part of the cylinder in the sheet width direction.

[0012] According to the third invention, due to the tension that pulls the drawing-in part to the back side of the pad, the slit-shaped anchor through-hole extending longitudinally in the sheet width direction can be pulled from both sides so that the opening does not open. Thereby, the inside of the hole of the pad through-hole can be more appropriately covered by the bottom cover part of the cylinder.

[0013] The fourth invention of the present invention is the second or third invention described above, wherein the pair of cylindrical cover parts are provided in a pair so as to cover the inner peripheral surfaces of the holes of the pair of pad through-holes provided in a pair in the sheet width direction on the sheet pad, and the pair of bottom cover parts of the cylinder are provided in a pair so as to cover the inside of the cylinders of the pair of cylindrical cover parts, and the drawing-in part is a pair of sheet covers that are drawn inward in the sheet width direction so as to pass through the back side of the pad from the pair of bottom cover parts of the cylinder and are connected to each other.

[0014] According to the fourth invention, the pair of drawing-in parts can be reasonably drawn to the back side of the pad.

Embodiments for Carrying out the Invention

[0016] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

[0017] 《First Embodiment》 (Schematic Configuration of Seat Cover 5) First, the configuration of the seat cover 5 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 9. In the following description, when indicating directions such as front, back, up, down, left, and right, the respective directions shown in each figure shall be referred to.

[0018] Also, when indicating each direction with "sheet" such as "sheet width direction", the respective directions based on the sheet 1 to be described later shall be referred to. Further, in the following description, when no specific reference figure is shown, or when there is no reference numeral corresponding to the reference figure, any one of FIGS. 1 to 9 shall be appropriately referred to.

[0019] As shown in FIG. 1, the seat cover 5 according to the present embodiment is applied to the seat 1 mounted on an automobile. The seat 1 has a seat back 2 that serves as the backrest portion of the seated occupant and a seat cushion 3 that serves as the seating portion. The lower end portions on both the left and right sides of the seat back 2 are connected to the rear end portions on both the left and right sides of the seat cushion 3 via a recliner (not shown). Thereby, the seat back 2 can adjust the backrest angle with respect to the seat cushion 3.

[0020] The seat back 2 is disposed directly above the rear end portion of the seat cushion 3. At the rear end portion of the seat cushion 3, a rising portion 3A that rises upward is formed so as to fill the gap between the lower end portion of the seat back 2. At two positions in the seat width direction of the rising portion 3A, the ISO-FIX type lower anchors LA are passed through from the back side so as to be exposed on the seat front side.

[0021] Each lower anchor LA serves as a fixture for fixing a child seat (not shown). Each lower anchor LA is coupled to a lower pipe 2A that extends in the seat width direction in the seat back side region of the rising portion 3A. Each lower anchor LA is composed of a single wire member bent in a U shape in plan view.

[0022] Specifically, each lower anchor LA is welded to the lower pipe 2A such that both legs of their U shape are arranged in the seat width direction. Each lower anchor LA is bent in a bent shape in side view such that both legs of their U shape extend obliquely upward in front of the seat from the joint portion with the lower pipe 2A.

[0023] The rising portion 3A has a seat pad 4 made of foamed urethane that covers the lower pipe 2A from the seat front side, and a seat cover 5 made of synthetic leather that is placed on the seat pad 4 from the seat front side. Note that the seat cover 5 may be made of fabric.

[0024] In the seat pad 4, at two positions in the seat width direction, pad through holes 4A that penetrate in a rectangular hole shape through which the corresponding lower anchor LA can be passed from the back side of the pad to the front side are formed. These pad through holes 4A are configured such that the corresponding lower anchor LA is passed to near the opening on the seat front side. Thereby, each lower anchor LA can be easily visually recognized when the user attaches a child seat (not shown).

[0025] The seat cover 5 has a top plate cover portion 5A that covers the top plate portion 4B excluding each pad through hole 4A of the seat pad 4. As shown in Figs. 2 to 5, the seat cover 5 has a pair of cylindrical cover portions 5B that extend in a rectangular cylindrical shape from the top plate cover portion 5A to the back side of the cover so as to cover the inner peripheral surfaces of each pad through hole 4A.

[0026] The seat cover 5 also has a pair of tube bottom cover pieces 5D extending from each of the tube cover parts 5B to close the tube opening on the tube bottom side. As shown in Figures 6 to 7, each of the pair of tube bottom cover pieces 5D is made of a single strip-shaped member. Each tube bottom cover piece 5D has a tube bottom cover part D1 that closes the tube opening on the tube bottom side of each of the tube cover parts 5B, and a retracted part D2 that extends from both edges of the tube bottom cover part D1 in the sheet width direction.

[0027] Each tube bottom cover portion D1 has an anchor through-hole D3 in the form of a slit extending in the seat width direction at a position near the rear edge thereof. As shown in Fig. 8, each anchor through-hole D3 is a through-hole for passing a corresponding lower anchor LA from the back side to the front side of the seat.

[0028] As shown in Fig. 7, the tube bottom cover portion D1 of each tube bottom cover piece 5D is sewn along all four edges of the tube bottom side of the corresponding tubular cover portion 5B. Also, as shown in Fig. 8, the tube bottom cover pieces 5D have their retracted portions D2 extending inward in the seat width direction from the tube bottom cover portion D1 retracted inward in the seat width direction so as to pass through the back side of the pad and overlap each other.

[0029] Furthermore, the retraction portion D2 extending outward in the seat width direction of each tube bottom cover piece 5D is also retracted outward in the seat width direction so as to pass through the back side of the pad and is engaged with each end of the seat cover 5 (see Figure 9) which is retracted to the back side of the pad through the gusset (peripheral side surface) of the seat pad 4.

[0030] As shown in Fig. 9, by these draw-ins, each bottom cylinder cover piece 5D is held in a state of being pulled from both sides so that the anchor through-holes D3 (see Fig. 7) formed in their bottom cylinder cover portions D1 do not open. Further, each bottom cylinder cover piece 5D is held so as not to float up to the front side of the pad from the corresponding pad through-hole 4A.

[0031] As shown in Fig. 7, specifically, the draw-in portions D2 extending inside in the sheet width direction of each bottom cylinder cover piece 5D are engaged with each other as follows. That is, the resin plate D4 sewn to the tip of one of these draw-in portions D2 is passed through the slit D5 formed in the other, and they are engaged with each other like a snap button. Thereby, the draw-in portions D2 are connected to each other. Note that the coupling method for connecting the draw-in portions D2 may be a coupling using male and female surface fasteners or a hooking using a hook.

[0032] Also, the engagement between each draw-in portion D2 extending outside in the sheet width direction described above and each terminal of the sheet cover 5 drawn to the back side of the pad through the flange (peripheral side surface) of the sheet pad 4 is performed in the same manner. As shown in Fig. 9, specifically, the engagement between each draw-in portion D2 and each terminal of the sheet cover 5 is such that the resin plate D4 sewn to the tip of one of these is passed through the slit D5 formed in the other, and they are engaged with each other like a snap button. The coupling method for connecting these may also be a coupling using male and female surface fasteners or a hooking using a hook.

[0033] As shown in Figs. 2 and 4, each cylindrical cover portion 5B is sewn into a square cylinder shape by a first inner cylinder cover piece B1 bent in a U shape in plan view covering the front side and the inner peripheral surfaces of the holes on the left and right sides of the corresponding pad through-hole 4A, and a second inner cylinder cover piece B2 covering the inner peripheral surface of the hole on the rear side. Three sides forming the upper edge of the U shape of the first inner cylinder cover piece B1 are sewn to the edge facing the corresponding pad through-hole 4A of the top plate cover portion 5A.

[0034] Further, the second inner cylinder cover piece B2 is overlapped on the back side of the cover of the top plate cover portion 5A and is stitched to the edge facing the corresponding pad through-hole 4A of the top plate cover portion 5A. And, for the second inner cylinder cover piece B2, both left and right side edges that are joined to the left and right rear edges of the U-shape of the first inner cylinder cover piece B1 are stitched to these. By these stitches, each cylindrical cover portion 5B is provided so as to extend in a rectangular tube shape from the top plate cover portion 5A toward the back side of the cover.

[0035] Each bottom cylinder cover portion D1 is disposed at a position that closes the bottom of the corresponding pad through-hole 4A. Therefore, the corresponding lower anchor LA passed through each pad through-hole 4A can be widely exposed inside the hole of each pad through-hole 4A. Each pad through-hole 4A is configured to be locked to the corresponding lower anchor LA inside the hole by fitting the corresponding lock portions protruding from two positions on the left and right at the lower end of the rear surface of a child seat (not shown) into the holes.

[0036] At that time, since each bottom cylinder cover portion D1 is at a position that closes the bottom of the corresponding pad through-hole 4A, it is difficult to push in each bottom cylinder cover portion D1 and it is difficult to cause sagging. Therefore, it is possible to appropriately suppress each bottom cylinder cover portion D1 from sagging in such a way as to open the mouth of the anchor through-hole D3 and the frame structure such as the lower pipe 2A on the inner side of the hole from the corresponding pad through-hole 4A from being exposed.

[0037] Summarizing the above, the seat cover 5 according to the present embodiment is configured as follows. Note that the reference numerals in parentheses below correspond to the respective configurations shown in the above embodiment.

[0038] That is, the seat cover (5) is a cover that is placed on a seat pad (4) having a pad through-hole (4A) through which a lower anchor (LA) of the ISO-FIX system passes. The seat cover (5) has a top plate cover portion (5A), a cylindrical cover portion (5B), and a bottom cover portion (D1). The top plate cover portion (5A) covers the top plate portion (4B) of the seat pad (4) excluding the pad through-hole (4A). The cylindrical cover portion (5B) extends from the top plate cover portion (5A) so as to cover the inner peripheral surface of the hole of the pad through-hole (4A) in a cylindrical shape along the inner peripheral surface of the hole. The bottom cover portion (D1) extends from the cylindrical cover portion (5B) so as to close the bottom opening of the cylinder, and has a slit-shaped anchor passage hole (D3) through which the lower anchor (LA) can pass through the cylinder.

[0039] According to the above configuration, when the lower anchor (LA) is passed through the anchor passage hole (D3) of the bottom cover portion (D1), it can be passed through the pad through-hole (4A) so that the lower anchor (LA) can be visually recognized from the outside. In addition, the inner part of the hole of the pad through-hole (4A) can be covered by the bottom cover portion (D1) so that the frame structure on the back side of the hole is not exposed.

[0040] Further, the seat cover (5) further has a drawing-in portion (D2) that draws in the cylindrical cover portion (5B) and / or the bottom cover portion (D1) toward the back side of the pad. According to the above configuration, it is possible to appropriately suppress the cylindrical cover portion (5B) and the bottom cover portion (D1) from rising from the pad through-hole (4A) to the front side of the pad.

[0041] Further, the anchor passage hole (D3) is in a slit shape that extends longitudinally in the seat width direction. The drawing-in portion (D2) draws in the bottom cover portion (D1) toward the back side of the pad so as to pull it in both directions in the seat width direction. According to the above configuration, due to the tension of drawing in the drawing-in portion (D2) to the back side of the pad, the slit-shaped anchor passage hole (D3) that extends longitudinally in the seat width direction can be pulled from both sides so that the opening does not open. Thereby, the inner part of the hole of the pad through-hole (4A) can be covered more appropriately by the bottom cover portion (D1).

[0042] Further, a pair of cylindrical cover portions (5B) are provided so as to cover the inner peripheral surfaces of the pad through-holes (4A) provided in pairs in the sheet width direction of the seat pad (4). Also, a pair of bottom cover portions (D1) are provided so as to cover the inside of the cylinders of the pair of cylindrical cover portions (5B) respectively. The drawing-in portions (D2) are configured as a pair that are drawn inward in the sheet width direction so as to pass through the back side of the pad from the pair of bottom cover portions (D1) and are connected to each other. According to the above configuration, the pair of drawing-in portions (D2) can be reasonably drawn into the back side of the pad.

[0043] 《Regarding Other Embodiments》 As described above, the embodiments of the present invention have been described using one embodiment, but the present invention can be implemented in various forms in addition to the above embodiments.

[0044] 1. The seat cover of the present invention may be configured by a single cover piece in which a part of the cylindrical cover portion and the bottom cover portion are seamless with each other. The pad through-hole may penetrate in a rectangular hole shape, or may be in a round hole shape, a polygonal hole shape other than a rectangle, or an irregular hole shape. The cylindrical cover portion may extend from the top plate cover portion so as to cover the inner peripheral surface of the pad through-hole in a cylindrical shape along the inner peripheral surface of the hole, and may have a cylindrical shape corresponding to the hole shape of the pad through-hole.

[0045] 2. The drawing-in portion may be configured by a single cover piece that is seamless with the bottom cover portion, or may be configured by another cover piece that is sewn to the bottom cover portion. Also, the drawing-in portion may be configured to extend seamlessly from the cylindrical cover portion. Further, the drawing-in portion may be sewn to the bottom cover portion and / or the cylindrical cover portion to draw one or both of them toward the back side of the pad.

[0046] The leading-in part may be fixed to the back surface of the pad or the frame by a coupling means such as a hook-and-loop fastener or a hog ring at the end drawn into the back side of the pad. The leading-in part may be configured to be drawn in only to either the inside or the outside in the sheet width direction. Further, the leading-in direction of the leading-in part may be either both or one of the sheet width direction and the sheet front-rear direction in addition to the sheet width direction.
