Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a seat skin hanging clip that suspends and fixes a seat skin terminal between a listing wire attached to the terminal of the seat skin and a cushion pad insert wire or a cushion spring for receiving a cushion pad. It is.
[0002]
[Prior art]
Conventionally, in a terminal where a skin material covering a seat surface and a skin material covering a bank surface are stitched together, a hanging bag is sewn and a listing wire is provided, and an axis of an insert wire embedded in a cushion pad The end of the seat skin is suspended and fixed by interposing a C-shaped ring in between, or hooking a coil spring between the cushion spring and the axis of the cushion spring that receives the cushion pad.
[0003]
In the structure in which the end of the seat skin is suspended, when a large tension is applied to the seat skin, the axis is opened and deformed in the case of a C-shaped ring, and in the case of a coil spring, the hook portion is opened and deformed, thereby causing an insert wire or cushion. In the case of a coil spring, the coil portion is fully extended, and the sheet skin is lifted or stretched.
[0004]
In particular, when the terminal of the skin material covering the bank surface and the skin material covering the side surface is sewn with the seat skin containing the airbag module, and when the seam is a rupture portion accompanying the expansion and expansion of the airbag, In order to effectively form the fractured portion by the inflation pressure of the airbag, it is necessary to suspend and fix each skin material so as to withstand the inflation pressure of the airbag.
[0005]
Of the skin material for sewing the broken portion, the end of the skin material covering the side surface can be firmly suspended and fixed by the seat back frame. On the other hand, since the C-shaped ring and the coil spring are used as described above in the terminal where the skin material covering the seat surface and the skin material covering the bank surface are sewn together, the suspended portion is air There is a possibility that it will be stretched by the expansion pressure of the back and will support the breaking of the fractured portion.
[0006]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to provide a seat skin hanging clip capable of firmly hanging and fixing a seat skin terminal by a simple operation so that the sheet skin does not float or stretch.
[0007]
[Means for Solving the Problems]
The suspension clip for a seat skin according to the present invention includes a substantially downward C-shaped base ring portion, a phase extending obliquely outward from each end of the base ring portion, and a free end crossing in a substantially X shape. It consists of a reverse J-shaped spring arm, and the axis of the listing wire is received inside the free end of the spring arm so that the base ring is hooked on the axis of the listing wire, and the axis of the insert wire or cushion spring is connected to the spring arm. It is configured as a clip that is received inside from the free end of and held by both spring arms.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, with reference to the accompanying drawings, FIG. 1 shows a case in which a terminal 1c stitched together between a skin material 1a covering a seating surface of a seat back and a skin material 1b covering a bank surface is suspended and fixed. Indicates. A suspension bag 2 is sewn to the terminal 1c of the seat skin, a listing wire 3 is provided in the bag, and a clip 6 is hooked between the cushion spring 5 and the axis of the cushion spring 5 to receive the cushion 1 of the seat skin 1. The terminal 1c is suspended and fixed.
[0009]
The hanging clip 6 extends in a substantially downward C-shaped base ring portion 6a as shown in FIGS. 2 and 3 and obliquely outward from each end of the base ring portion 6a as shown in FIGS. In addition, the free ends are formed of spring arms 6b and 6c having a substantially J-shape opposite to each other and crossing in a substantially X-shape. Further, it can be formed as a bent metal product or a resin molded product of a metal wire or metal plate material having a spring property that the free end side is phase-separated or phase-matched.
[0010]
The clip 6 first hangs the clip 6 by receiving the axis of the listing wire 3 inward from the slightly opened free ends of the spring arms 6b and 6c and hooking the base ring portion 6a on the axis of the listing wire 3. Attach to hang down to 2.
[0011]
When attaching the clip 6, as shown in FIG. 1, it passes through the punched hole 4a of the cushion pad 4 together with the hanging bag 2, and as shown in FIG. 5, the free ends of the spring arms 6b and 6c are widened to expand the cushion spring 5. Press against the axis. As a result, the clip 6 receives the axis of the cushion spring 5 inside the free ends of the spring arms 6b and 6c as shown in FIG. 6, and receives the axis of the cushion spring 5 as shown in FIG. 7 between the spring arms 6b and 6c. The terminal 1c of the seat skin 1 can be easily hung and fixed by being held inside and supported by the bent portion.
[0012]
When the seat cover is suspended by the clip, the restoring force of both spring arms 6b and 6c is also applied, and the axis of the cushion spring 5 can be strongly held and supported by the bent portions of both spring arms 6b and 6c. For this reason, even if a large tension is applied to the seat skin 1, the spring arms 6b and 6c can be prevented from opening and deforming or extending, and the seat skin 1 can be lifted and stretched without being detached from the cushion spring 5. The terminal 1c can be firmly suspended and fixed so as not to exist.
[0013]
As shown in FIG. 8, the suspension of the seat skin by the clip is a seat back in which the airbag module E is incorporated, and the skin material 1b that encloses the bank surface on the airbag module incorporation side and the skin material that encapsulates the side surface. This is suitable for forming the stitched portion with 1d as a rupture portion 1e accompanying the inflation and deployment of the airbag.
[0014]
In the case of the seat skin, the terminal 1 f of the skin material 1 d enclosing the side surface can be firmly suspended and fixed by the bracket plate 7 a of the seat back frame 7. At the same time, the above-described suspension may be applied to the terminal 1c stitched together between the skin material 1a encapsulating the seat surface and the skin material 1b encapsulating the bank surface. Since both can be suspended and fixed so as to counter the inflation pressure of the airbag, the inflation pressure can be concentrated on the breaking portion 1e as the airbag is inflated and deployed, so that the breaking portion 1e can be effectively cleaved.
[0015]
The above-described embodiment has been described based on the case of being suspended and fixed between the listing wire attached to the terminal of the seat skin and the cushion spring for receiving the cushion pad. The same can be applied to the suspension between the two.
[0016]
【The invention's effect】
As described above, according to the clip for hanging the seat skin according to the present invention, the base ring portion is hooked on the axis of the listing wire, and the spring arm is simply hooked on the insert wire or the axis of the cushion spring. The terminal of the seat cover can be suspended and fixed with a simple operation. In addition, because the cushion spring or insert wire axis is held and supported by both spring arms, even if a large tension is applied to the seat cover, the spring arm can be prevented from opening and deforming or extending, causing the seat cover to float or stretch. The terminal can be firmly suspended and fixed so that there is not.
[0017]
In particular, in a seat back with a built-in airbag module, the stitched portion of the skin material covering the bank surface on the side where the airbag module is built and the skin material covering the side surface is formed as a fractured portion due to the expansion and deployment of the airbag. When applied to the device, the inflation pressure of the airbag can be concentrated on the rupture portion as the airbag is inflated and deployed, so that the rupture portion can be effectively cleaved.
