Abstract

PROBLEM TO BE SOLVED: To allow a side air bag to expand out from an arbitrary position of a gusset part of a seat, by providing a seam to be split by an expansion of the air bag and opened to the gusset part of a back rest on a side gusset cover part. SOLUTION: A side gusset cover part 33 is split into two of right and left halves 33a and 33b which are sewn together to constitute a seam part 4. As the sewing thread, thin and weak-to-pressure one, for instance, monofilament of cotton, hemp, acrylate, etc., or shin and weak, i.e., hollow thread, is used. As the sewing system, abutting sides of right and left halves 33a and 33b are folded inward and folded end abutting parts are sewn together. A usually used back in sewing method is not used in this sewing. Thus the seam part 4 comes to be in so-called tacks which is easily broken by an extent of the pressure of the side air bag expansion. Expanding-out of the side air bag is enabled by opening of only a part of the side gusset part as a cover fitting condition is kept.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called half cover for covering only an upper portion of a backrest of a seat, and a seat cover for covering a seat, which is used for an automobile seat having a side airbag. About.

[0002]

2. Description of the Related Art Conventional automobile seat covers include a so-called seat cover that covers substantially the entire surface of a seat backrest, and a so-called half cover that covers only the upper peripheral portion of the seatback. Each seat cover is formed in a bag shape with a lower opening, and a seat backrest 62 is provided.
Front surface 63, upper surface 64, rear surface 65, and both side surfaces (gore portion) 6
6 (see FIGS. 7 and 8). At the time of mounting on the seat, the seat backrest 62 is externally fitted onto the seatback 62 with the lower opening of the cover body down from above the upper surface 64 of the seatback.

[0003]

In recent years, the front seats (the driver's seat 6A and the passenger seat 6 provided via the console box 67) of the automobile have side airbags attached to the backrest gore portions 66 on the door side, respectively. (Impact buffer device that jumps out by impact) 2 is built in. The side airbag 2 is housed in a cover plate 21 which is normally opened and closed by an applied impact (see FIG. 7). On the other hand, the conventional seat cover has a bag shape with a lower opening as described above, and is configured to cover at least the entire upper surface of the seat backrest 62. That is, the cover is formed so as to cover the gore portion 66 of the seat backrest 62. Therefore, the conventional seat cover (seat cover, half cover) hinders the side airbag 2 from jumping out of the backrest gore portion 66 and cannot be used.

[0004] It is an object of the present invention to solve the above-mentioned problems and to provide an automobile seat cover that allows a side airbag disposed at an arbitrary position of a seat gore portion to protrude.

[0005]

In order to achieve this object, a vehicle seat cover according to the present invention has the following configuration. An automobile seat cover is a cover for covering an automobile seat in which a side airbag is incorporated in a side gore portion of a seat backrest. It is characterized in that a cover portion is provided with a sewn portion that opens to the backrest gore portion.

In a vehicle seat cover having such a configuration, for example, a side gore cover portion is divided into two right and left sheets.
The folded overlapped ends of the left and right halves are sewn with a suture to form a sewn portion. The sewn portion is not subjected to so-called reverse sewing (back sewing), and is sewn in a temporary sewing shape with a thread that is weak to pressure. In other words, the sewn portion is arranged in the plane of the side gore cover portion, for example, from the front side. When a large impact is applied to the vehicle, the side airbag incorporated in the backrest gore portion protrudes outward from the gore portion. At this time, the seam of the corresponding side gore cover is torn by a large popping pressure of the side airbag. As a result, the two left and right halves forming the side gore cover portion are opened at the same time as the side airbag jumps out. Therefore, the side gore cover portion allows the side airbag to jump out and does not hinder the jumping out.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an automobile seat cover according to the present invention.
FIG. 1 is a perspective view showing the first embodiment, and FIG. 2 is a partially enlarged sectional view.

The automobile seat cover includes a so-called seat cover that covers the entire backrest 62 of the seat and a so-called half cover that covers only the upper part of the seat backrest 62. In the present embodiment, an example is shown in which a side seam portion 33 of the seat cover is torn by the side airbag jumping out and the stitching portion 4 is provided to open the side gore cover portion 33 to the backrest gore portion 66.

The seat cover (seat cover) includes a seat cover 5 that covers the upper surface and the peripheral gore of the seat 61 of the front seat, and a backrest cover 3 that covers the seat backrest 62. The backrest cover 3 includes a front cover portion 31 that covers the front surface 63 of the seat backrest 62, an upper surface cover portion 32 that is continuous with the upper side of the front cover portion 31 and covers the upper surface 64 of the backrest, and a tip side of the upper surface cover portion 32. And a side gore cover portion 33 that covers the backrest gore portion 66. The peripheral edges of the side gore cover 33 are a front cover 31, an upper cover 32, and a back cover 34.
Is sewn to one end.

In the first embodiment, the side gore cover 3
3 is divided into two right and left halves 33a and 33b, and the left and right halves 33a and 33b are sewn with a suture 41 to form a suturing portion 4. The suture thread 41 is a thin thread that is weak to pressure, for example, a single fiber such as cotton thread, hemp thread, acrylic thread,
Alternatively, a thin and weak so-called hollow fiber is used. In addition, as shown in FIG.
The abutting portion side of 3b is bent inward, respectively, and this bent joint end is sewn with a suture thread 41. Further, in this suturing, back sawing (reverse stitching) performed in normal sewing is not performed. As a result, the stitching portion 4 becomes a so-called temporary stitching (temporary fixing) stitching that is easily torn by a large pressure when the side airbag 2 jumps out. Further, the distal ends of the bent joint ends of the left and right halves 33a, 33b are bent inward, respectively, and sewn to prevent bending (stitching stitching lines 42). The suturing line 42 has no relation to the sewing strength (tear strength) of the sewn portion 4, but maintains the folded state.

FIG. 3 is a side view showing another embodiment. In this embodiment, one side of the back cover 34 is extended to form the side gore cover 33 integrally and continuously, and the stitching portion 4 is attached to the joint between the side gore cover 33 and the front cover 31. Make up. The suture 41 and the suturing method are performed in exactly the same manner as in the previous embodiment (FIG. 1). In this embodiment, the sewn portion 4 is not provided in the surface of the side gore cover portion 33, but is sewn to the front side (front portion) of the side gore cover portion 33, that is, the overlapped end with the front cover portion 31. A part 4 is provided. Therefore, the side gore cover portion 33 is moved forward by the side airbag 2 protruding.
Is torn open.

FIG. 4 is a side view showing still another embodiment. In this embodiment, a single side gore cover 3
The suturing portion 4 is provided on the entire periphery of the sewn portion 3. The suture 41 and the suturing method are performed in exactly the same manner as in the previous embodiment (FIG. 1). In this embodiment, the side gore cover 3
A seam 4 is formed at a joint between the front cover 3, the front cover 31, the top cover 32, and the back cover 34.
Therefore, the entire periphery of the side gore cover portion 33 is torn by the protrusion of the side airbag 2, and the entire side gore cover portion 33 is separated from the backrest cover 3.

FIG. 5 is a side view showing another embodiment. In this embodiment, the stitching portion 4 is provided only on the upper peripheral portion of the side gore cover portion 33. The suture 41 and the suturing method are implemented in exactly the same manner as in the previous embodiment (FIG. 1). In this embodiment, the stitching portion 4 is formed at an upper portion of the side gore cover portion 33 and at a joint portion with the front cover portion 31, the upper surface cover 32, and the back cover portion 34. Therefore, when the side airbag 2 jumps out, the lower part of the side gore cover portion 33 is not torn, but only the upper portion is torn, allowing the side airbag 2 to jump out.

In the automobile seat cover having such a configuration, as shown in FIG. 1, the cover plate 2 of the gore portion 66 containing the side airbag 2 in a normal state with the cover attached.
1 is a side gore cover portion (left and right halves 33a, 33b) 33
And cannot be seen.

When a large impact is applied to the vehicle, the side airbag 2 incorporated in the backrest gore portion 66 jumps out of the gore portion 66 when the open / close lid plate 21 is opened. At this time,
The stitching portion 4 of the side gore cover 33 is torn by the popping pressure of the opening / closing lid plate 21 and the side airbag 2, and the side gore cover 33 is opened at the same time as the side airbag 2 pops out (see FIG. 6). That is, the suture 41 of the suture portion 4 is
A thread that is extremely thin and weak against pressure is used, and a so-called reverse stitch is not adopted as a sewing method, and a so-called temporary sewing state is set. Therefore, the suture portion 4 is very easily torn by the large pop-out pressure of the side airbag 2.

More specifically, in the first embodiment (FIG. 1), the suturing portion 4 for sewing the left and right halves 33a and 33b is torn, and the surface of the side gore cover portion 33 is opened in a divided manner. The backrest gore 66 is opened. Further, the second embodiment (FIG. 3)
Then, the sewn portion 4 arranged at the front part (front side) of the side face gore cover part 33 is torn, the front part of the side face gore cover part 33 is opened, and the entire backrest gore part 66 is opened. Further, in the third embodiment (FIG. 4), the sewn portion 4 provided on the entire peripheral edge of the side gore cover portion 33 is torn, and the entire side gore cover portion 33 is detached from the backrest cover 3 and The gore portion 66 is opened. In the fourth embodiment (FIG. 5), the side gore cover 3
The sewn portion 4 arranged on the upper peripheral portion 3 is torn, and only the upper portion of the side gore cover portion 33 is opened to open the backrest gore portion 66.

Thus, the side gore cover portion 33 completely covers the gore portion 66 of the seat backrest 62 in a normal state similarly to the conventional seat cover, and covers the side airbag 2 of the backrest gore portion 66 normally. Cannot be seen.
However, when a large impact is applied, the side airbag 2 is allowed to jump out, and does not hinder the jumping out.

[0018]

According to the present invention, as described above, a cover for covering an automobile seat in which a side airbag is incorporated in a side gore portion of a seat backrest, and a side airbag is provided on a side gore cover portion of the backrest cover. Since the bag is torn out, the side gore cover section is provided with a sewn portion that opens to the backrest gore section, so that in a so-called seat cover that covers the entire backrest or a so-called half cover that covers only the upper part of the backrest, By opening only the side gore cover portion with the cover attached, the side airbag can pop out. Therefore, unlike the conventional cover, there is no possibility that the side gore cover portion hinders the side airbag from protruding from the backrest gore portion. In addition, the arrangement position of the side airbag provided in the backrest gore part, particularly the vertical position, is slightly different depending on each automobile maker and various types of vehicles. Since it is open, it has excellent effects that achieve the object of the invention, such as being able to be universally mounted and used in various types of vehicles.
