    [0001] BACKGROUND OF THE INVENTION The present disclosure relates to a seat cover of a vehicle seat and the vehicle seat. Background A vehicle seat (to which reference is simply hereinafter referred to as "seat"), such as a car seat, comprises a seat frame constituting a seat structure and seat padding defining an outer shape of the seat. seat. In addition, a complete outer surface of the seat padding is covered with a seat cover to improve the design. At present, the seat cover must be brought into close contact with a three-dimensional shape (irregular shape) of the seat padding. In the associated art, as indicated for example in JP-A-2012-187 254, the seat cover comprising a portion covering a seating surface is configured by a large number of small subdivision pieces to correspond to to the three-dimensional shape of the seat upholstery. Peripheral edges of each piece are sutured to one another to form a seat cover part. Nevertheless, in the case in which the seat cover is configured by a large number of small subdivision parts as in the related art, a number of components is increased and therefore a great effort is required to suture each piece. In general, the seat cover is connected to the seat padding. At present, the portion of the seat cover connected to the seat padding becomes stiff due to an adhesive and, therefore, the extensibility and flexibility thereof is lost. Depending on the location of the connection or the range of the connection, there is a problem that a great deal of effort is required to cover the seat upholstery with the seat cover where it is difficult to bring about. the seat cover to follow the irregular shape of the seat padding, which commonly causes folds. Aspects of the present disclosure provide for a seat cover in which the number of components is reduced to reduce suture effort and easily follows a three-dimensional shape of a seat pad, and a vehicle seat comprising the seat cover. seat. According to one aspect of the disclosure, there is provided a seat cover of a vehicle seat configured to cover an outer surface of a seat pad, wherein a portion of the seat cover that is configured to overlap at least a seating surface of the seat pad consists of a seat surface part consisting of a piece of fabric, and in which, when the outer surface of the seat pad is covered, the seat cover is connected only to the seating surface. It is therefore proposed a seat cover of a vehicle seat to cover an outer surface of a seat padding. The seat cover has a portion configured to cover at least one seating surface of the seat padding. The part of the seat cover consists only of a seat surface part consisting of a piece of fabric. This means that the seating surface of the upholstery is only covered by one piece. Here, the term "seating surface" refers to a surface on which the body of an occupant and the seat are in contact when the occupant sits in a normal posture. Specifically, a front surface in the case of a seatback or headrest corresponds to the seating surface, and an upper surface in the case of a seat cushion corresponds to the seating surface. . Further, in the case where side support portions are provided to provide bulges on both sides of the seat, an inner surface (a center surface in plane relative to a reference seating surface) with 3 portions upper lateral support portions as borders corresponds to the seating surface. When the outer surface of the seat pad is covered with the seat cover, the seat cover is connected only to the seat surface.
    [0002] In the seat cover described above, it is preferable that one part of the seat cover other than the seat surface part consists of a non-seating surface part consisting of a part. fabric, so that a complete seat cover is configured by two pieces of fabric. Provided that at least the seating surface is covered with a piece, the portion of the seat cover other than the seat surface piece can be configured by several pieces. Nevertheless, it is preferable that the part of the seat cover other than the seat surface part also consists of a non-seating surface part consisting of a piece of fabric. This means that it is preferable that the complete seat cover is configured by two pieces of fabric. In the seat cover described above, it is preferred that a head restraint portion configured to support an occupant's head be integrally provided to an upper portion of the seat pad and, when covering the surface In the outer seat padding, the seat cover is not connected to a seat surface of the head restraint portion. In the case where the seat padding is used as a seat back and a portion of the headrest configured to support the head of an occupant is integrally provided to a top portion of the seat padding, the seat padding and the seat cover may also be connected to a front surface (seating surface) of the headrest portion. However, in the case where the headrest portion is integrally provided to the upper portion of the seat padding, it is preferable that the seat cover is not connected to the seating surface of the seat portion. headrest so that the seat cover is easily assembled with the seat padding 3036668 when the outer surface of the seat padding is covered by the seat cover. According to the seat cover of the present disclosure, at least the seating surface is covered with a workpiece and, therefore, the number of parts of the complete seat cover can be reduced. In this way, a suture effort of each piece can be reduced. In addition, the portion, which is not connected to the seat pad, can be easily stretched or deformed. Therefore, in the case where the seat cover is connected only to the seating surface when the seat pad is covered by the seat cover, the portion of the seat cover other than the connected portion may follow. enough to avoid a problem such as the deformation of the shape of the seat or the occurrence of folds, when the portion of the seat cover other than the portion of the part 15 of the seat seat surface also consists of only one piece of non-sitting surface consisting of a piece of fabric, the complete seat cover can be configured by two pieces.This way, a suture effort of each piece can be In the case where the headrest portion is integrally provided to the upper portion of the seat padding, the seat cover may accurately follow an irregular shape. peciale the portion of the headrest when the seat cover is not connected to the seat surface of the portion of the headrest. According to another aspect of the disclosure, there is provided a vehicle seat comprising: a seat pad having a seating surface; and a seat cover covering an outer surface of the seat padding and comprising: a first piece of fabric entirely covering the seating surface of the seat pad; and a second piece of fabric covering a portion of the outer surface of the seat pad that is not covered by the first piece of fabric, wherein the seat cover is connected only to the seating surface. In the vehicle seat described above, it is preferable that the seat cover consists of the first piece of fabric and the second piece of fabric.
    [0003] In the vehicle seat described above, it is preferable for the seat pad to comprise a seat portion and a headrest portion integrally connected to the seat portion and configured to support the head of an occupant, each of the seat portion and the headrest portion having a seating surface, and the seat cover is connected to the seating surface of the seat portion and is not connected to the surface the seat portion of the headrest portion.

The front piece 22f and the back piece 22r are sutured at their peripheral edges. The front piece 22f corresponds to the seating surface part of the present disclosure. The back piece 22r corresponds to the non-seating surface piece of the present disclosure. The back cover 22 corresponds to the seat cover of the present disclosure. As also shown in FIG. 3, the front piece 22f is cut into a shape to cover a lateral surface of the seat back 2 extending from the top of the two side support portions 2S to the portion of the seat. headrest 2H and an upper surface of the seat back 2 (headrest portions 2H), in addition to the seating surface. The back piece 22r is cut into a shape to completely cover the portion other than the portion covered by the front piece 22f. As the material of the backrest cover 22, a fabric having excellent extensibility on an associated backrest cover is used. Specifically, in the associated backrest cover, a force of about 100 N is required to obtain a 10% circular module. Nevertheless, in the back cover 22 of the present embodiment, a force of about 20 N or less is sufficient to obtain a 10% circular module. To express the excellent extensibility, the back cover 22 of the present embodiment is configured so that a weave yarn is roughly 20% to 30% woven on the back cover in the associated art and a normal thread. made of PP or the like and a crimped yarn having high extensibility are mixed in a ratio of 1: 1. Referring to FIG. 2, the seat cushion 3 also includes a cushion frame 30 constituting a structure of the seat cushion 3, a cushion cushion 31 as a cushion material, and a cushion cover 32 for covering a cushion. upper surface and a side surface of the cushion padding 31. The cushion frame 30 is made of a metal. A basic configuration of the cushion frame 30 is not particularly limited. The cushion frame 30 may have a basic configuration that is known in the art for this type of vehicle seat. Specifically, the cushion frame 30 has two left and right side frames 30a, a front panel 30b connecting front end portions of the two side frames 30a, and a rear pipe 30c connecting rear end portions. two side frames 30a, or similar elements. Two left and right guides 33 are arranged on a lower surface of the seat cushion 3 and are attached to a vehicle floor (not shown). In this way, the seat 1 is movable in the longitudinal direction of the vehicle. The cushion frame 31 is made of resin foam, such as a polyurethane foam, of a predetermined shape and defines a three-dimensional shape of the seat cushion 3. Therefore, the seat surface 3A, the two portions of 3S side support and the seating surface of the seat cushion 3 are defined by the cushion padding 31. The seating surface is configured by the seat surface 3A and an inner surface (center surface 10 in the width direction ) of the two lateral support portions 35. The cushion padding 31 also corresponds to the seat padding of the present disclosure. The cushion cover 32 is configured as two pieces comprising a seat surface piece 32u to cover the seating surface and a side surface piece 32s to cover a side surface of the cushion pad 31. The surface piece The seat 32u and the lateral surface piece 32s are sutured at their peripheral edges. The seat surface piece 32u is cut into a substantially quadrangular shape so as to cover the entire seating surface. The side surface piece 32s is cut into a band-like shape so as to cover the side surface of the cushion liner 31. Here, as the material of the cushion cover 32, a normal fabric, which is woven by a fiber similar to PP fiber in the related art is used. The side surface piece 32s corresponds to the non-seating surface piece of the present disclosure. The cushion cover 32 corresponds to the seat cover of the present disclosure. A method of covering an outer surface of the back upholstery 21 with the back cover 22 will be described hereinafter. As shown in Fig. 4, the front piece 22f and the back piece 22r are sutured in the state in which the back cover 22 is turned over. The reference number 3036668 22i indicates a sutured portion. As shown in Fig. 5, an adhesive W is applied to predetermined regions of the back upholstery 21, and the back upholstery 21 and the back cover 22 are thermofixed together. At present, the adhesive W is applied only to the seating surface other than the headrest portion 2H. This means that the adhesive W is applied only to the seat surface 2A and the inner surface of the two side support portions 2S. In Figure 5, an application range (a connecting range of the back pad 21 and the back cover 22) of the adhesive W is represented by a dotted line.
    [0006] As shown in FIG. 6, the back cover 22 covers the back upholstery 21 and is returned to a non-linking portion. At present, the back upholstery 21 and the backrest cover 22 are connected to each other only to the seating surface except outside the headrest portion 2H, so that the Portions other than the connected portion have a high degree of freedom of deformation. As shown in FIG. 7, there is no case in which the back upholstery 21 deforms or folds form in the back cover 22. In addition, the back cover 22 may cover precise and smooth backrest upholstery 21 following the irregularities of the file upholstery 21.
    [0007] Similarly, in the seat cushion 3, the cushion pad 31 and the cushion cover 32 are connected to each other only to the seating surface. Since the cushion cover 32 covers only the upper surface and the side surface of the cushion pad 31, it is sufficient for the cushion pad 31 to be covered by the cushion cover 32 from above.
