Description

  The present invention relates to a vehicle seat, and more particularly to a high-back type vehicle seat.

  Conventionally, a vehicle seat in which a seat back pad constituting a seat back and a head rest pad constituting a headrest are integrally formed and the surfaces of both pads are integrally covered by a seat cover, a so-called high back type Vehicle seats (hereinafter simply referred to as “high-back seats”) are already known. Here, in Patent Document 1 below, a notch groove is provided in the boundary portion between the seat back pad and the headrest pad among the surfaces of both pads, and a high back in which a part of the seat cover is bitten into the notch groove. A sheet is disclosed. Thereby, since a feeling of suspension can be given to the boundary portion between the seat back pad and the headrest pad, even if it is a high back seat, the seat back and the headrest can be shown as being formed separately.

JP 11-47465 A

  However, in the above-described prior art, since a feeling of suspension is obtained by biting a part of the seat cover into the notch groove on the pad surface, there has been a problem that a firm feeling of suspension cannot be obtained. In order to solve this problem, a wire is inserted into the notch groove of the pad like a suspension applied to a seat cover of a general vehicle seat, and this wire and the inner surface of the seat cover are ringed. It was also conceived that a feeling of hanging was produced by joining (for example, hogging). However, this idea requires a wire, and thus a new problem has occurred in that the number of parts increases.

  The present invention is intended to solve such problems, and its purpose is to secure a feeling of suspension at the boundary between the seat back and the headrest without requiring a large number of parts even in the high back type. It is providing the vehicle seat which can be taken out.

The present invention is for achieving the above object, and is configured as follows.
According to the first aspect of the present invention, there is provided a seat back pad that constitutes a seat back, a head rest pad that constitutes a headrest, and a seat cover that integrally covers the surfaces of both pads assembled to a frame of the seat back. The vehicle seat is provided, and at the boundary between these two pads, the inner surface on the front side and the inner surface on the rear side of the seat cover are fastened along the boundary in a tensioned state. The seat cover is integrally covered on the surfaces of both pads.
According to this configuration, in the state where the upper edge portion of the seat back pad in the seat cover and the lower edge portion of the headrest pad in the seat cover are respectively drawn toward the inside of the seat back 3, the seat cover and the seat back pad Covering can be performed integrally with the surface of the headrest pad. Therefore, as described in the related art, a feeling of hanging at the boundary between the seat back and the headrest can be obtained firmly without requiring a large number of parts (without requiring a wire).

The invention according to claim 2 is the vehicle seat according to claim 1, wherein the headrest pad has an insertion hole for receiving the front end of the frame for assembling the headrest pad to the frame of the seat back. It is formed, and the insertion hole is provided with a stopper that holds about half the degree of reception of the front end of the frame.
According to this structure, when inserting the front-end | tip of a back frame in a headrest pad, the insertion can be hold | maintained (temporarily fixed) in the state performed about half. Thereby, since a work space can be secured between the seat back pad and the headrest pad, it is possible to easily perform hooking using the space.

According to a third aspect of the present invention, there is provided a vehicle seat comprising: a seat pad that constitutes a seat back and a headrest; and a seat cover that covers a surface of the seat pad assembled to a frame of the seat back. In addition, a through hole penetrating in the thickness direction is formed at the boundary between the seat back and the headrest in the seat pad, and the seat is formed along the boundary between the seat back and the headrest through the through hole. The inner surface on the front side and the inner surface on the rear side of the cover are fastened in a tensioned state, and the seat cover in the hooked state is covered on the surface of the seat pad.
According to this configuration, not only the same effects as those of the first aspect can be obtained, but also the seat back pad can be made into one configuration. Therefore, the effect that this pad can be manufactured simply can be acquired.

  Hereinafter, the form for implementing this invention is demonstrated using FIGS. In the following description, as described in the related art, the high back seat 1 will be described as an example of the vehicle seat. Further, in the following description, the terms “up”, “down”, “front”, “back”, “left”, and “right” refer to the directions of “up”, “down”, “front”, “back”, “left”, and “right” described in the above-described drawings. When up, down, front, back, left, right are shown.

  First, with reference to FIGS. 1-3, the structure of the high back seat | sheet 1 which concerns on the Example of this invention is demonstrated. The high back seat 1 includes a seat cushion 2 and a seat back 3 having a headrest 4. Of these seat cushion 2 and seat back 3, the detailed configuration of the seat back 3 will be described. Since the seat cushion 2 may have a known configuration, a detailed description thereof will be omitted.

  The seat back 3 includes a back frame 10, a seat back pad 20, a headrest pad 30, and a seat cover 40. Below, these structural members 10, 20, 30, and 40 are demonstrated separately.

  First, the back frame 10 will be described. The back frame 10 is formed so that its tip (upper end) is tapered so as to form a skeleton of the seat back 3 and the headrest 4.

  Next, the seat back pad 20 will be described. The seat back pad 20 is a pad member that constitutes the seat back 3. The seat back pad 20 is formed in an enveloping manner with respect to the back frame 10 so as to be able to receive a backrest load of an occupant seated on the seat cushion 2.

  Next, the headrest pad 30 will be described. The headrest pad 30 is a pad member that constitutes the headrest 4. The headrest pad 30 is formed so as to be able to be inserted into a tapered portion of the tip (occupant) of the back frame 10 so as to receive a load from the back of the occupant seated on the seat cushion 2.

  Therefore, the headrest pad 30 is formed with an insertion hole 32 that can receive the tapered portion at the tip of the back frame 10. The insertion hole 32 is formed so that the inner wall surface on the back side rises from the inner wall surface on the inlet side. This description corresponds to “the insertion hole is provided with a stopper that holds about half the degree of reception of the end of the frame” described in the claims. Thereby, when inserting the tapering site | part of the front-end | tip of the back frame 10 in the headrest pad 30, it can hold | maintain (temporarily fix | stop) in the state where about the insertion was performed.

  Finally, the seat cover 40 will be described. The seat cover 40 includes a seat back cover 42 that can cover the surface of the seat back pad 20, and a headrest cover 44 that can cover the surface of the headrest pad 30. These covers 42 and 44 are sewn before and after the boundary portion between the seat back 3 and the headrest 4 (the upper surface portion of the seat back pad 20 and the lower surface portion of the headrest pad 30) (N in FIG. 2). , N indicates sewing locations).

  At these sewing locations N and N, the sides 48a and 48a of the substantially rectangular resin plates 48 and 48 are also sewn along the longitudinal direction (left and right direction). On the other sides 48b and 48b facing the sides 48a and 48a of the both resin plates 48 and 48, shaft-shaped shafts 48c and 48c are formed so as to rise along the other sides 48b and 48b themselves. The shaft bodies 48c and 48c are formed in a size that is separated from each other (in a state having a gap F between the shaft bodies 48c and 48c in FIG. 3) when the shaft bodies 48c are in a state before performing a hogling operation described later. Has been.

  Next, a procedure for assembling the high-back seat 1 from the back frame 10, the seat back pad 20, the headrest pad 30, and the seat cover 40 will be described with reference to FIGS.

  First, as shown in FIG. 3, only the seat back cover 42 of the seat cover 40 is turned upside down, and the headrest pad 30 is inserted into the headrest cover 44 of the seat cover 40 in this inverted state, so that the surface of the headrest pad 30 is Covering is performed by the headrest cover 44. Next, as shown in FIGS. 4 and 5, the seat back pad 20 is assembled to the back frame 10 in the inverted state, and the headrest pad 30 is inserted into the front end of the back frame 10 in the assembled state. At this time, the headrest pad 30 is inserted only about half without being completely inserted into the tip of the back frame 10.

  Then, as shown in FIG. 6, the shaft bodies 48c and 48c of the resin plates 48 and 48 sewn to the seat cover 40 are brought close to each other in the inserted state, and the shafts 48c and 48c are brought close to each other via the jig 60. The bodies 48c and 48c are tightened (hoggled) by the C-ring 50. This description corresponds to “the fastening of the inner surface on the front side and the inner surface on the rear side of the seat cover in a state in which tension is applied along the boundary at the boundary between both pads” in the claims. . As a result, the two resin plates 48 and 48 are drawn toward each other (because the gap F between the two shaft bodies 48c and 48c is filled), so the upper edge of the seat back cover 42 and the lower edge of the headrest cover 44 Are drawn inward toward each of these.

  Finally, the headrest pad 30 is completely inserted into the front end of the back frame 10, the seat back cover 42 turned over is returned, and the surface of the seat back pad 20 is covered by the seat back cover 42 (see FIG. 2). In addition, since the structure which latches the covered seat back cover 42 on the seat back pad 20 is a known structure, the detailed description thereof will be omitted. In this way, the assembly of the high back sheet 1 is completed.

  The high back sheet 1 according to the embodiment of the present invention is configured as described above. According to this configuration, in the state where the upper edge of the seat back cover 42 and the lower edge of the headrest cover 44 are retracted toward the inside of the seat back 3, the seat cover 40 is attached to the seat back pad 20 and the headrest pad 30. It is possible to cover the surface integrally. Therefore, as described in the prior art, a feeling of hanging at the boundary between the seat back 3 and the headrest 4 can be firmly obtained without requiring a large number of parts (without requiring wires).

  Further, according to this configuration, the insertion hole 32 of the headrest pad 30 is formed so that the inner wall surface on the back side rises from the inner wall surface on the entrance side. Therefore, when the tapered portion at the tip of the back frame 10 is inserted into the headrest pad 30, it can be held (temporarily fixed) in a state in which about half of the insertion has been performed. Therefore, since a work space can be secured between the seat back pad 20 and the headrest pad 30, hogging can be easily performed using this space.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In the embodiment, the example in which the seat back pad 20 and the headrest pad 30 are configured separately has been described. However, the present invention is not limited to this, and the seat back pad 120 and the headrest pad 130 may be integrally formed (see FIG. 7). In this case, a through-hole 122 that penetrates in the thickness direction (front-rear direction) must be formed at the boundary between the seat back 3 and the headrest 4 in both the pads 120 and 130. Then, the above-described hoggling may be performed through the through hole 122.

  These descriptions are described in the claims, “A through hole penetrating in the thickness direction is formed at the boundary between the seat back and the headrest in the seat pad, and the seat back is formed through the through hole. The front cover's inner surface and the rear surface's inner surface are fastened along the boundary between the headrest and the headrest, and this seat cover is covered on the surface of the seat pad. '' It corresponds to. Note that, with this integrated configuration, the seat back pad 120 and the headrest pad 130 can be configured with one pad as compared with the case of the separate configuration. Therefore, the effect that these both pads 120 and 130 can be manufactured simply can be acquired.
