(First embodiment)
The seat 1 includes a seat 2 that can move back and forth on the floor panel of the vehicle, and a backrest 3 that can recline relative to the seat 2. Each of the seat 2 and the backrest 3 is a seat member constituting the seat 1 and includes a cushion material 4 made of a foam. Further, a dressing cover (seat cover) 7 can be attached to and detached from the seat 2 and the backrest 3 by using a hanging structure 10. The seat 2 and the backrest 3 are provided with a plurality of line-like hanging grooves 11 constituting the hanging structure 10 (see FIG. 1).

Here, the backrest 3 will be described as an example. The cushion material 4 constituting the backrest 3 has a main cushion portion 41 for supporting the occupant's back from the rear and a side cushion portion 42 for holding the occupant's back from the side (see FIG. 2). ). A hanging groove 11 for hanging and supporting the dressing cover 7 is provided at a boundary portion between the main cushion portion 41 and the side cushion portion 42 or the like. The surface of the cushion material 4 is covered with a base cover (hereinafter referred to as a base trim cover) 6 by, for example, adhesion or integral foam molding.

The dressing cover 7 includes a main surface portion 71 placed on the main cushion portion 41 of the cushion material 4, a side surface portion 72 placed on the side cushion portion 42, and a side surface that covers the side portion of the side cushion portion 42. And a side portion 73 (see FIG. 2). The main surface portion 71 and the side surface portion 72 of the dressing cover 7 are joined together by a stitching portion 74 in a state where the surfaces of the dressing cover 7 are partially in contact with each other. Then, when the cushion member 4 and the base trim cover 6 are put on, the front portions of the stitching portion 74 and the dressing cover 7 from the stitching portion 74 are not exposed to the surface side (see FIG. 2).

Further, the hanging portion 75 of the dressing cover 7 is a portion inserted into the hanging groove 11. In the present embodiment, a portion including a region provided with a stitching portion 74 and a locking member 76 (referred to simply as “inclined pile” in the present specification) made of a cloth including a skin of the inclined pile is a suspended portion. 75 is constituted. Note that the stitching portion 74 is not an essential component for the hanging portion 75, but serves as a mark (leading edge) or a leading portion (bending edge) when the hanging portion 75 is inserted into the hanging groove 11. In some cases, 75 may play a role of increasing resistance so that it is difficult to remove 75 from the hanging groove 11.

Also, the outer cover of the dressing cover 7 is attached to the backrest 3 or the seat 2 by the outer peripheral dressing fastener 8. In addition, in this specification and drawing, only the example of arrangement | positioning (refer FIG. 1) and the simple structure (refer FIG. 4) of the outer peripheral part dressing fastener 8 are shown, and detailed description is abbreviate | omitted. Although not particularly shown, a wadding may be provided between the base trim cover 6 and the dressing cover 7.

The suspension structure 10 that suspends and supports the dressing cover 7 includes a suspension groove 11, a suspension portion 75, and an inclined pile 76 (see FIG. 2 and the like).

The hanging groove 11 is formed of a concave portion formed at a predetermined depth extending along the vertical direction or the horizontal direction (width direction) of the backrest 2 at the boundary portion between the main cushion portion 41 and the side cushion portion 42 or the like. Thus, the appearance of the seat 1 is formed, and the hanging portion 75 used for hanging the dressing cover 7 is accommodated. Normally, the hanging groove 11 is pressed and closed by the elasticity of the cushion material 4, but for convenience, FIG. 2 shows the hanging groove 11 in an expanded state for easy understanding.

The inclined pile 76 is provided in the hanging portion 75 by sewing or the like so as to be reverse hair in the drawing direction, and locks the dressing cover 7 inserted into the hanging groove 11 (FIGS. 2, 3 and the like). reference). In the present embodiment, inclined piles 76 are provided on both sides of the stitched portion (bending edge) 74 to increase the contact area with the hanging groove 11 and increase the locking force (pull-out resistance). Note that the reverse hair includes not only the reverse hair that coincides with the pulling direction but also the case where it is inclined to the left or right with respect to the pulling direction. In short, the dressing cover 7 is suspended. Any material can be used as long as it is capable of exerting a sufficient locking force.

The inclined pile 76 is made of a synthetic resin material (for example, plastic) or a fiber made of a soft linear shape in a raised state. On the other hand, as the base trim cover 6 with which the inclined pile 76 contacts, there is a base trim cover 6 that suspends and supports the dressing cover 7 when the inclined pile 76 is engaged, for example, a bolster recot or a raised tricot having a loop. Suitable. The inclined piles 76 are caught by these skins and are strongly fixed in the shearing direction to generate a resistance force (frictional force) in the tensile direction.

Further, the dressing cover 7 may be provided with another inclined pile 77 in contact with the side portion of the backrest 3 (or the seat 2) on the periphery thereof. In the present embodiment, another inclined pile 77 is sewn on the back surface of the side surface side portion 73 of the dressing cover 7, and the dressing cover 7 is covered with the surface of the brushed tricot surface on the side portion (gusset portion) of the base trim cover 6. To engage.

Further, in the dressing cover 7, a throttle portion 78 is provided in a portion around another inclined pile 77 (see FIGS. 2 and 3). The restricting portion 78 increases the degree of contact between the other inclined pile 77 and the side portion (gusset portion) of the base trim cover 6 and increases the engagement force. The restricting portion 78 is configured, for example, by sewing a rubber string 78a on the edge of the dressing cover 7 (see FIG. 3 and the like).

The other suspending groove 11 of the backrest 3 and the suspending groove 11 in the seat 2 and the suspending structure 10 constituted by these (except for the other inclined pile 77, the narrowed portion 78, etc.) are shown in FIG. Since it has the same configuration as the hanging groove 11 and the hanging structure 10 shown in FIG.

According to the suspension structure 10 of the seat 1 of the present embodiment described so far, the dressing cover 7 is mounted by inserting and inserting the suspension portion 75 provided with the inclined pile 76 into the suspension groove 11. (See FIG. 4). Also, the dressing cover 7 can be removed or easily removed by grasping an appropriate position of the dressing cover 7 and pulling it firmly and pulling the hanging part 75 out of the hanging groove 11. The attachment and detachment work is very simple so that it can be put into a state. In particular, when the dressing cover 7 is mounted, it can be mounted by a simple operation of inserting and inserting a fingertip from the front side into the hanging portion 75 (see FIG. 4). In addition, when the suspended portion 75 is suspended and supported, the inclined pile 76 is forward so that it is easy to insert, and after that, it becomes a reverse eye (reverse hair) and is difficult to come off.

Further, in this hanging structure 10, a closing pressure is applied to the hanging groove 11 using the elasticity of the cushion material 4 constituting the seat member (seat 2, backrest 3), and a frictional force (engagement) is applied to the inclined pile 77. Resultant force).

In addition, since the catching position of the inclined pile 76 can be adjusted steplessly, it is pushed in while pushing the suspension part 75 little by little into the seat member (seat 2 and backrest 3) that is a three-dimensional shape based on ergonomics. By adjusting the amount (hanging amount), it is possible to reduce wrinkles so that the skin of the dressing cover 7 is not left excessive. Therefore, unlike a hanging structure using fasteners, even if the hanging position is not strictly constant, a design error can be easily absorbed and handled easily.

Also, since the core material and insert member in the hanging structure using fasteners are not necessary, the configuration is simple and there is no sense of foreign matter. This is also advantageous in terms of storage, transportation and cleaning.

(Second Embodiment)
In the present embodiment, the inclined pile 76 is provided only on one surface of the stitched portion (bending edge) 74 and is brought into contact with the hanging groove 11. Thus, the dressing cover 7 can be suspended and fixed by exerting a predetermined locking force (pullout resistance force) also by the inclined pile 76 provided only on one side (see FIG. 5). Although not shown, similarly, the inclined pile 76 can be provided only on one side of the surface of the base trim cover 6 and inside the hanging groove 11.

(Third embodiment)
Part of the cover (base trim cover) of the seat member (seat 2 and backrest 3) can be sewn into a pocket shape to provide the hanging groove 11. As a specific example, in this embodiment, a portion of the backrest 3 that is close to the seat 2, for example, a part of the base trim cover 6 at the bottom of the backrest 3 is sewn in a pocket shape with the entrance facing forward. A hanging groove 11 extending in the direction is formed (see FIG. 6). Further, a hanging portion 75 including an inclined pile 76 is provided on the edge of the dressing cover 7, and the hanging portion 75 is locked by being pushed into the hanging groove 11 from the front, and the dressing cover 7 is suspended. Can be supported. For example, the backrest 3 is reclined around the rotation center 3 </ b> C by avoiding the suspending portion 75 from coming into contact with the other seat member (the seat 2 in this embodiment) by the pocket-shaped suspending groove 11. In this case, it is possible to avoid the suspended portion 75 from rubbing and affecting the suspended holding state of the base trim cover 6 (see FIG. 7).

The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, the seat 1 according to the present invention can be used for an aircraft seat, a passenger ship seat, and the like in addition to a vehicle seat, and further, uses other than vehicles and vehicles (furniture, office goods, etc.) It can be applied to other sheets.

In the above-described embodiment, the example in which the seat cover is the dressing cover 7 has been described. However, this is also only a preferable example. In addition, for example, the seat cover may be easily attached and detached so that the cover can be easily cleaned or the seat ground can be cleaned. In short, the seat cover is utilized by using the suspension structure 10 such as the suspension groove 11. If it is the sheet | seat 1 which suspends and supports, this invention can be applied irrespective of the specific name, main use, etc. of the said seat cover.

Further, in the above-described embodiment, the form in which the inclined pile 76 is provided on the back surface of the dressing cover 7 is illustrated, but this is only a suitable example. In addition, the suspended structure 10 can be configured by providing an inclined pile 76 on the surface of the base trim cover 6 positioned in the suspended groove 11. Alternatively, it is also possible to provide the suspended structure 10 in which the inclined piles 76 are provided on both the back surface of the dressing cover 7 and the surface of the base trim cover 6 located in the hanging groove 11 so that the inclined piles 76 are in contact with each other ( (See FIG. 4).

In the above-described embodiment, the form in which the inclined pile 76 is brought into contact with the surface of the base trim cover 6 is illustrated (see FIG. 2 and the like). For example, the inclined pile 76 may be brought into contact with the surface of the main cushion portion 41 or the surface of the side cushion portion 42 in a state where the base trim cover 6 is not covered, and in short, an aspect in which the dressing cover 7 can be locked. If it is.
