[0004] [Patent Document]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2020-175844 Summary of the invention

[0006] [Problems to be Solved by the Invention]

[0007] In the structure described in Patent Document 1, the seat cover is arranged to be in a tensioned state that does not cause floating or wrinkling when the leg rest is stored. Therefore, when the leg rest is unfolded, wrinkles are generated due to the reduction in the distance between the leg rest body and the fixing portion. If the wrinkles are randomly generated in a position visible to the user, the appearance of the seat may be damaged. Therefore, the present invention provides a seat cover that can limit the position of wrinkles generated by the unfolding of the leg rest to an area that is difficult for the user to see.

[0008] [Methods for solving the problem]

[0009] As means for solving the above-mentioned problems, the seat cover of the present invention adopts the following means.

[0010] That is, the first invention of the present invention is a seat cover covering a leg rest portion arranged on the front side of a seat cushion, wherein the seat cover comprises: a main cover portion, which covers the leg rest body of the leg rest in a close-fitting manner from the surface side; an extended cover portion, which extends in a manner of being introduced from the upper edge of the main cover portion to the fixed portion below the top plate of the seat cushion; and a first limiting portion, which is combined with a first portion of the extended cover portion that is closer to the leg rest body than the fixed portion from the back side of the cover, and reinforces the first portion to limit the location where wrinkles are generated to the area between the first portion and the fixed portion, and the wrinkles are generated in the extended cover portion due to the shortening of the distance between the leg rest body and the fixed portion accompanying the unfolding of the leg rest.

[0011] According to the first invention, wrinkles generated in the seat cover due to the deployment of the leg rest can be limited to the area of ​​the extended cover portion introduced below the top plate of the seat cushion, which is further back than the first limiting portion. As a result, wrinkles generated in the seat cover can be less visible to the user.

[0012] The second invention of the present invention is a seat cover, which, in the above-mentioned first invention, also has a second limiting portion, which is connected to the second part of the extended cover part from the back side of the cover, and reinforces the second part to limit the location where the wrinkles are generated to the area between the first part and the second part, that is, the third part, and the second part is between the first part of the extended cover part connected to the first limiting portion and the fixing part.

[0013] According to the second invention, the position of wrinkles generated in the seat cover can be limited to the third area between the first limiting part and the second limiting part of the extended cover portion. Thus, the position of wrinkles generated in the extended cover portion can be controlled with higher accuracy.

[0014] The third invention of the present invention is a seat cover. In the above-mentioned second invention, the extended cover portion has the following length: through the reinforcement generated by the first limiting portion and the second limiting portion, as the leg rest portion is unfolded, the first limiting portion sneaks into the lower side of the second limiting portion in a manner of reversing the front and back sides, and the third portion is bent in a manner of extending from the first portion and the second portion to the front of the seat in a folded state.

[0015] According to the third invention, as the leg rest is unfolded, the extension cover can be compactly folded so as to be difficult for the user to see.

[0016] The fourth invention of the present invention is a seat cover. In the above-mentioned second or third invention, the second part of the extended cover part combined with the second limiting part abuts against the bottom of the top plate of the seat cushion by bending, and the bending is caused by the shortening of the distance between the leg rest part main body and the fixing part accompanying the expansion of the leg rest part.

[0017] According to the fourth aspect of the present invention, wrinkles can be appropriately generated between the first portion and the second portion of the extended cover portion using the second portion abutting against the lower side of the top plate of the seat cushion as a fulcrum.

[0018] The fifth invention of the present invention is a seat cover, in the above-mentioned second or third invention, the first limiting portion and the second limiting portion are respectively composed of flat plates, and the plates are in contact with the extended cover portion in a planar shape from the back side of the cover in a manner extending over the entire area in the seat width direction.

[0019] According to the fifth invention, the first restricting portion and the second restricting portion can be compactly arranged so as to overlap in a layered manner along the surface shape of the extended cover portion.

[0020] The sixth invention of the present invention is a seat cover. In any one of the first to third inventions mentioned above, the leg rest body comprises: a base connected to the seat cushion in a manner that allows it to rotate around an axis extending in the width direction of the seat; and a top plate connected to the base in a manner that allows it to slide in the direction of the rotation radius of the axis, and the main body cover covers the base in a close contact manner from the surface side.

[0021] According to the sixth aspect of the present invention, even if the leg rest body is structured such that the top plate slides relative to the base, wrinkles generated in the seat cover can be made less visible to the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] <<First Implementation Method>>

[0054] (Schematic Structure of Seat Cover 3)

[0055] First, use Figure 1 to Figure 8 The structure of the seat cover 3 according to the first embodiment of the present invention will be described. In the following description, when directions such as front, back, up, down, left, and right are indicated, these directions are indicated in the drawings.

[0056] In addition, when "seat" is indicated in various directions such as "seat width direction", it means various directions based on the seat cushion 10 described later. In the following description, when no specific reference figure is shown or when there is no corresponding symbol in the reference figure, a reference shall be made to the reference figure as appropriate. Figure 1 to Figure 8 Any of the graphs in .

[0057] like Figure 1As shown, the seat cover 3 of this embodiment is configured as a cover of the leg rest 1 provided in front of the seat cushion 10 of the automobile seat. The automobile seat includes a seat back (not shown) serving as a backrest for a seated passenger, a seat cushion 10 serving as a seat portion, and the leg rest 1 serving as a footrest.

[0058] The surface of the leg rest 1 is covered by a leather seat cover 3. Figure 2 As shown, the leg rest 1 is configured such that a leg rest body 2 as a main body thereof includes a flat plate-shaped base 2A rotatably connected to the seat cushion 10 and a flat plate-shaped top plate 2B slidably connected to the base 2A.

[0059] The base 2A is connected to the seat cushion 10 so as to be rotatable about an axis R extending in the seat width direction. Specifically, upper ends of left and right side edges of the flat plate of the base 2A are connected to the seat cushion 10 via electric joint devices (not shown).

[0060] Thus, the base 2A moves around the axis R as each joint device is driven. Figure 1 The storage position shown is the same as Figure 2 The base 2A is deployed / stored between the deployed positions shown. The base 2A is stopped at an arbitrary position by using the braking force by stopping the driving of each joint device.

[0061] Base 2A Figure 1 The storage position shown is arranged so as to hang down to the front edge of the top plate of the seat cushion 10, that is, directly below the top plate front edge 11. Figure 2 As shown, as the base 2A is deployed forward from the above-mentioned storage position, the flat plate stands up with the axis R as the center, and the axis R is located directly below the top plate front edge 11 .

[0062] The top plate 2B is arranged to overlap the flat plate of the base 2A and is connected to the base 2A via an electric sliding device (not shown) provided between the left and right side edges thereof so as to be slidable in the longitudinal direction of the flat plate (direction of the rotation radius of the axis R).

[0063] Thus, the top plate 2B moves relative to the base 2A as the slide devices are driven. Figure 1 The storage position shown is the same as Figure 2 By stopping the driving of each slide device, the top plate portion 2B stops at an arbitrary position by the braking force thereof.

[0064] The top plate 2B is configured so that Figure 1 In the storage position shown in FIG. 1 , the seat cushion 10 is overlapped with the base 2A and hangs down directly below the top plate front edge 11 of the seat cushion 10. Figure 2As shown, the top plate 2B slides forward from the above-mentioned storage position as the base 2A is deployed, and is thereby pulled forward so that the overlap with the base 2A becomes shallow.

[0065] The leg rest body 2 is moved while the base 2A is rotated and the top plate 2B is slid simultaneously. Figure 1 The storage position shown is the same as Figure 2 In addition, the leg rest body 2 can also be opened / stored between the base 2A and the unfolded position shown. Figure 1 The storage position shown is Figure 2 The expanded position shown is the expanded position, and the expansion / storage is performed by sliding the top plate portion 2B.

[0066] Through such a structure, the leg rest body 2 can Figure 1 The storage position shown is stored in a compact posture with the top plate 2B deeply overlapped on the base 2A. Figure 2 The deployed position shown can be deployed to an expanded posture that is optimal for a footrest by pulling the top plate 2B forward from the base 2A.

[0067] The seat cover 3 includes a main body cover portion 3A covering the leg rest main body 2 and an extended cover portion 3B extending from the upper edge of the main body cover portion 3A to be introduced directly below the top plate front edge portion 11 of the seat cushion 10. The main body cover portion 3A includes a base cover portion A1 covering the base 2A from the surface side and a top plate cover portion A2 covering the top plate portion 2B from the surface side.

[0068] The base cover A1 and the top cover A2 are composed of separate cover pieces. The extended cover 3B is configured to extend seamlessly from the upper edge of the base cover A1. The end of the introduced front end of the extended cover 3B is hooked from above by a hook B4 to a front pipe 12 provided just below the top front edge 11 of the seat cushion 10. Here, the front pipe 12 corresponds to the "fixing portion" of the present invention.

[0069] like Figure 3~Figure 4 As shown, the front pipe 12 constitutes a frame extending in the seat width direction along the front edge of the seat cushion 10. The front pipe 12 is located obliquely above and rearward of the axis R which is the rotation center of the leg rest body 2. The extended cover portion 3B is formed to have a length that is extended to such an extent that tension is weakly applied between the base 2A and the front pipe 12 when the leg rest body 2 is located in the storage position.

[0070] Therefore, if Figure 5As shown in the figure, the extended cover 3B is relaxed in a manner that wrinkles are formed between the base 2A and the front tube 12 as the leg rest body 2 is unfolded, that is, the base 2A rotates forward from the storage position, and the distance between the base 2A and the front tube 12 is shortened. At this time, if wrinkles are randomly formed in a position visible to the user, there is a concern that the appearance of the seat will be damaged.

[0071] Therefore, the seat cover 3 of this embodiment has a structure that can limit the location of the wrinkles to an area that is difficult for the user to see. Specifically, the extended cover portion 3B is provided with a first limiting portion 4A that reinforces the first portion B1 close to the base 2A thereof, and a second limiting portion 4B that reinforces the second portion B2 between the first portion B1 and the hook B4.

[0072] The first limiting portion 4A and the second limiting portion 4B limit the position of wrinkles in the extension cover 3B when the leg rest body 2 is unfolded so that wrinkles are generated in the third portion B3 between the first limiting portion 4A and the second limiting portion 4B. The detailed structures of the extension cover 3B and the base cover A1 are described in detail below.

[0073] (Regarding the base cover A1 and the extension cover 3B)

[0074] like Figure 6 Specifically, the base cover A1 is bonded to the top plate surface and the left and right sides of the base 2A with double-sided tape A over substantially the entire area.

[0075] The extended cover portion 3B is formed in a shape extending from the upper edge (the edge on the inner side in the figure) of the portion of the base cover portion A1 covering the top plate surface of the base 2A with the same width as the portion. The left and right side edges of the extended cover portion 3B are seamlessly connected to the extended portions on both sides extending from the upper edge (the edge on the inner side in the figure) of the portion of the base cover portion A1 covering the left and right side surfaces of the base 2A.

[0076] The extended cover 3B has a hook B4 sewn along the edge of the front end thereof. In addition, the extended cover 3B has a first restricting portion 4A, which is composed of a horizontally long resin plate connected to a first portion B1 closer to the base cover A1 than the hook B4 from the cover back side. The first restricting portion 4A is provided at a position separated from the base cover A1.

[0077] In addition, the extended cover portion 3B has a second limiting portion 4B, which is composed of a horizontally long resin plate connected to the second portion B2 between the first portion B1 and the hook B4 from the cover back side. The first limiting portion 4A and the second limiting portion 4B are respectively horizontally long flat plate structures having a lateral width substantially the same as the lateral width of the extended cover portion 3B.

[0078] The first restricting portion 4A and the second restricting portion 4B are respectively in planar contact with the extended cover portion 3B over the entire area in the seat width direction (strictly speaking, substantially the entire area with both ends left) from the cover back side. Furthermore, the first restricting portion 4A and the second restricting portion 4B are respectively sewn to the extended cover portion 3B over the entire area in the seat width direction by two outer sewing lines extending in the seat width direction (sewing portion S).

[0079] like Figure 4 (and as a partial enlarged view thereof Figure 7 ), when the base 2A is in the storage position, the extended cover 3B is maintained in a state of being extended substantially straight between the base 2A and the front pipe 12. In this state, the extended cover 3B is in a state where the second portion B2 reinforced by the second restricting portion 4B is located directly below the top plate front edge 11 of the seat cushion 10.

[0080] like Figure 5 (and as a partial enlargement of Figure 8 ), as the base 2A rotates forward from the storage position, the extension cover 3B is pushed upward and backward by the base cover A1 formed integrally with the base 2A. As a result, the extension cover 3B is bent in such a way that the second portion B2 abuts against the bottom surface of the top plate front edge 11 of the seat cushion 10.

[0081] Along with this, the first portion B1 reinforced by the first restricting portion 4A is pressed into the extended cover portion 3B with the second portion B2 as a fulcrum so as to be embedded under the second portion B2. Furthermore, the extended cover portion 3B is further pressed into the extended cover portion 3B by the upward thrust accompanying the rotational movement of the base 2A so as to reverse the front and back of the first portion B1. As a result, the third portion B3, which is the area between the first portion B1 and the second portion B2 of the extended cover portion 3B, is bent so as to extend from the first portion B1 and the second portion B2 toward the front of the seat in a folded shape.

[0082] Specifically, the extended cover portion 3B is folded into an inverted Z-shape (a stacked shape along the surface shape of the extended cover portion 3B) with the second portion B2 as the upper side, the base cover portion A1 (first portion B1) as the bottom side, and the first portion B1 and the third portion B3 (third portion B3) as the oblique sides, and is compactly bent. By folding in this way, even if the extended cover portion 3B is bent due to the rotational movement of the base 2A, it will not cause a problem that the extended cover portion 3B deeply enters the interior of the seat cushion 10 and interferes with peripheral components such as the frame.

[0083] Furthermore, even if the user can see the third portion B3 of the extended cover 3B that extends forward in a folded shape toward the front of the seat, the folded portion extends straight in the seat width direction, and the appearance is not easily impaired. In this way, the seat cover 3 can appropriately control the deformation mode of the extended cover 3B so that the position of wrinkles generated by the unfolding of the leg rest body 2 can be limited to an area that is difficult for the user to see.

[0084] As the base 2A rotates, the cushion of the top plate front edge 11 of the seat cushion 10 is elastically deformed in a manner of being flattened from below. It should be noted that the first portion B1 of the extended cover portion 3B refers to the entire surface contact area with the first restricting portion 4A reinforced by the first restricting portion 4A contacting in a planar manner from the cover back side. Similarly, the second portion B2 refers to the entire surface contact area with the second restricting portion 4B reinforced by the second restricting portion 4B contacting in a planar manner from the cover back side.

[0085] In summary, the seat cover 3 of the present embodiment has the following structure. In addition, the reference numerals in parentheses below are reference numerals corresponding to the respective structures shown in the above-mentioned embodiment.

[0086] That is, the seat cover (3) is a cover for covering a leg rest (1) provided at the front side of a seat cushion (10). The seat cover (3) comprises: a main cover part (3A) covering a leg rest main body (2) of the leg rest (1) in a manner of being in close contact with the surface side; and an extended cover part (3B) extending from the upper edge of the main cover part (3A) to be introduced into a fixing part (12) under the top plate of the seat cushion (10).

[0087] The seat cover (3) has a first limiting portion (4A) connected from the back side of the cover to a first portion (B1) closer to the leg rest body (2) than the fixing portion (12) of the extended cover portion (3B). The first limiting portion (4A) reinforces the first portion (B1) so as to limit the position of wrinkles generated in the extended cover portion (3B) due to the reduction in the distance between the leg rest body (2) and the fixing portion (12) accompanying the expansion of the leg rest portion (1) to the area between the first portion (B1) and the fixing portion (12).

[0088] According to the above structure, the position of wrinkles generated in the seat cover (3) due to the unfolding of the leg rest portion (1) can be limited to a region further back than the first limiting portion (4A) of the extended cover portion (3B) introduced below the top plate of the seat cushion (10). As a result, the wrinkles generated in the seat cover (3) can be made difficult for a user to see.

[0089] The seat cover (3) further comprises a second limiting portion (4B) connected to a second portion (B2) from the back side of the cover, the second portion (B2) being between a first portion (B1) connected to the first limiting portion (4A) and a fixing portion (12) of the extended cover portion (3B). The second limiting portion (4B) reinforces the second portion (B2) by limiting the location of wrinkles to a third portion (B3) between the first portion (B1) and the second portion (B2).

[0090] According to the above structure, the position where wrinkles are generated in the seat cover (3) can be limited to the third portion (B3) which is the area between the first limiting portion (4A) and the second limiting portion (4B) of the extended cover portion (3B). Thus, the position where wrinkles are generated in the extended cover portion (3B) can be controlled with higher accuracy.

[0091] In addition, the extended cover portion (3B) has such a length that, by reinforcing the first restricting portion (4A) and the second restricting portion (4B), the first restricting portion (4A) is inserted under the second restricting portion (4B) in a manner of reversing the front and back sides as the leg rest portion (1) is unfolded, and the third portion (B3) is bent in a manner of extending from the first portion (B1) and the second portion (B2) toward the front of the seat in a folded shape. According to the above structure, as the leg rest portion (1) is unfolded, the extended cover portion (3B) can be compactly folded in a manner that is difficult for the user to see.

[0092] In addition, the second portion (B2) of the extended cover (3B) connected to the second limiting portion (4B) abuts against the lower portion of the top plate of the seat cushion (10) due to the deflection caused by the reduction in the distance between the leg rest body (2) and the fixing portion (12) as the leg rest (1) is unfolded. According to the above structure, wrinkles can be appropriately generated between the first portion (B1) and the second portion (B2) of the extended cover (3B) with the second portion (B2) abutting against the lower portion of the top plate of the seat cushion (10) as a fulcrum.

[0093] In addition, the first limiting portion (4A) and the second limiting portion (4B) are respectively formed of a flat plate, and the flat plate is in planar contact with the extended cover portion (3B) from the cover back side over the entire area in the seat width direction. According to the above structure, the first limiting portion (4A) and the second limiting portion (4B) can be compactly arranged in a stacked manner along the surface shape of the extended cover portion (3B).

[0094] In addition, the leg rest body (2) comprises: a base (2A) connected to the seat cushion (10) in a manner that allows rotation around an axis (R) extending in the seat width direction; and a top plate (2B) connected to the base (2A) in a manner that allows sliding along the rotation radius direction of the axis (R). The main body cover (3A) covers the base (2A) in a tightly fitting manner from the surface side. According to the above structure, even if the leg rest body (2) is a structure in which the top plate (2B) slides relative to the base (2A), it is difficult for the user to see wrinkles generated on the seat cover (3).

[0095] 《Regarding other implementation methods》

[0096] As mentioned above, although the embodiment of the present invention was described using one embodiment, the present invention can be implemented in various forms other than the above-described embodiment.

[0097] 1. The seat cover of the present invention only needs to be a cover that covers the leg rest portion provided at the front side portion of the seat cushion, and can be applied to seats mounted on vehicles other than vehicles such as automobiles and railways, as well as seats mounted on aircraft and ships. In addition, the seat cover can also be applied to seats other than vehicles.

[0098] 2. The leg rest body may be composed of a single layer structure rotatably connected to the seat cushion, in addition to a two-layer structure of a base rotatably connected to the seat cushion and a top plate slidably connected to the base.

[0099] 3. The seat cover may be made of a fabric material in addition to leather materials such as synthetic leather and natural leather. In addition, the seat cover may be made of a cover structure that combines leather materials and fabric materials.

[0100] 4. The seat cover may be configured such that the extended cover portion does not include the second restricting portion but includes only the first restricting portion. In this case, wrinkles generated in the seat cover due to the deployment of the leg rest portion are limited to a region further inward than the first restricting portion of the extended cover portion.

[0101] 5. In the above embodiment, there is no particular mention of the difference in width between the reinforcement area of ​​the first limiting portion and the second limiting portion, but the widths of the respective reinforcement areas may be the same or different. The first limiting portion and / or the second limiting portion may be provided locally or intermittently in a plurality rather than continuously over the entire area in the seat width direction relative to the extended cover portion.

[0102] If the interval between the first portion of the extended cover where the first limiting portion is coupled and the leg rest body is narrower than the interval between the second portion of the extended cover where the second limiting portion is coupled and the first portion, it is easy to limit the location where wrinkles are generated to the area between the first portion and the second portion, i.e., the third portion. The first limiting portion and / or the second limiting portion may be coupled to the extended cover by means other than sewing, such as double-sided tape or adhesive.

[0103] 6. With regard to the configuration in which the extended cover portion is bent in such a manner that the first restricting portion is embedded under the second restricting portion as the leg rest portion is deployed, the first restricting portion may be embedded under the second restricting portion and need not be embedded directly below. In addition, with regard to the configuration in which the first restricting portion is bent in such a manner that the first restricting portion is embedded under the second restricting portion, the first restricting portion may be embedded without reversing the front and back surfaces.
