Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a vehicle seat trim cover end processing structure for fixing the end portion of the trim cover covering the pad material of the vehicle seat to the seat frame. .

<<Prior Art>> In a vehicle seat such as an automobile, force is applied to the seat cushion or seat back in a direction along its surface as the seat accelerates, decelerates, changes direction, etc. Therefore, in order to prevent the trim cover covering the surface of the seat pad material from peeling off under any force, it is necessary to fix the end of the trim cover to the seat frame. There is.

As shown in FIG. 5, for example, as an end treatment structure of such a trim cover, a metal ring 5 is attached to an end portion 4 of a trim cover 3 covering a pad material 2 supported by a substantially frame-shaped seat frame 1. A plurality of engagement holes 6 are provided with edges, and hooks 7 for hooking the engagement holes 6 of the terminal portion 4 are formed on the seat frame 1 side by cutting and raising, and the pad material 2 is pressed and compressed. It is known that the end portion 4 of the trim cover 3 is locked to the seat frame 1 at multiple locations by strongly pulling the end portion 4 of the trim cover 3 and locking the engagement hole 6 to the hook 7. .

<<Problems to be solved by the invention>> By the way, in such a conventional structure, when the end portion 4 of the trim cover 3 is locked to the hook 7 of the seat frame, the end portion 4 is held in a state where the pad material 2 is pressed and compressed. 4 with a fairly strong force to sequentially engage the plurality of engagement holes 6 with the corresponding hooks 7. For this reason, the engagement work must be performed for the number of engagement holes 6, resulting in poor workability and a heavy burden on the operator.

The present invention was developed in view of these problems, and provides a trim cover end processing structure for a vehicle seat, which has a structure that allows the end portion of the trim cover to be securely and easily fixed to the seat frame. The purpose is to provide.

<<Means for solving the problem>> In order to achieve this object, in the present invention, the pad material supported by the seat frame is covered with a trim cover, and the end part of the cover is connected to a locking part provided on the frame. A trim cover end processing structure for a vehicle seat that engages and fixes the end portion of the trim cover, the structure including a plurality of engaging members provided with locking claws that engage with the locking portion of the frame, the end portion of the trim cover is folded back to form a bag-like part, and a wire having both ends protruding from each other is rotatably attached to the bag-like part, and the plurality of wires are attached to each of the notches formed in the bag-like part. The engaging member is fixed, and the wire is rotated while the terminal portion is pulled to engage and fix the locking pawl to the locking portion.

<<Operation>> With this configuration, when the end portion is pulled to rotate the wire, the locking claw of the engagement member on the trim cover side is engaged with the locking portion on the seat frame side at once. Therefore, the work of sequentially engaging and fixing multiple engagement holes in the conventional structure is no longer required, and each end part only needs to be pulled strongly once and the wire is rotated, improving work efficiency and making the work easier. The burden on people will also be reduced.

<<Example>> Hereinafter, an example of the present invention will be described based on the drawings.

1 to 3 show an embodiment of the vehicle seat trim cover terminal processing structure according to the present invention, and FIG. 1 is an exploded perspective view of a schematic configuration of a seat cushion to which the same structure is applied FIG. 2 is a longitudinal cross-sectional view of the main parts of the seat cushion, and FIG. 3 is a perspective view showing the structure of the main parts at the end of the trim cover shown in FIGS. 1 and 2.

1 to 3, the seat cushion 10 includes a substantially frame-shaped metal seat frame 12 to which a cushion spring 11 is attached, a pad material 13 supported on this frame 12, and a pad material 13 supported on this frame 12. The trim cover 14 covers the outer surface of the trim cover 14.

The seat frame 12 has a rectangular bottom wall 16 with an opening 15 in the center, and side walls 71 bent upward on each side of the bottom wall 16. A bent end wall 18 is formed so as to be bent downward. Further, reinforcing plates 19 are provided on the inner walls of the bottom wall portion 16 and the side wall portions 71 at each portion 16,
17 in succession. Further, on the bottom wall portion 16, locking portions 20 are formed by cutting and raising a part of the bottom wall portion 16 along each side wall portion 17.
is provided. In addition, the frame 12 has a pad material 1 whose top surface and four sides are covered with a trim cover 14.
3 is placed and supported in a recessed portion 13a formed on the lower surface of this pad material 13 in a state where it is housed until the tip edge of the side wall portion 17 comes into contact with it. The trim cover 14 has a bag made by folding back and sewing a part of the terminal part 25 on each side part 21, 22, 23, 24 that covers the side surface of the pad material 13. A shaped portion 26 is formed (see FIG. 2). A relatively rigid metal wire 28 having end portions 27 protruding from both sides of the bag-like portion 26 is provided within the bag-like portion 26 . Further, an engaging member 30 is fixed to the wire 28 at each notch 29 formed in the bag-shaped portion 26, and the engaging member 30 rotates together with the wire 28. The engaging member 30 is made of a relatively hard synthetic resin such as polyvinyl chloride, and is provided with a locking pawl 31 folded back into a U-shape on the free end side.

In the vehicle seat trim cover terminal processing structure configured as described above, when the terminal portion 25 of the trim cover 14 is fixed to the frame 12, the terminal portion 2
5 as a whole to bring the bag-like part 26 close to the locking part 20 of the frame 12, then pull the bag-like part 26 downward.
The operator holds both ends of the wire 29 protruding from both sides of the wire 28 and rotates the wire 28 in the direction of arrow A (see FIGS. 2 and 3). And this wire 2
8 is rotated, all the engaging members 30 fixed to this wire 28 rotate simultaneously, and the locking claw 3
1 moves to a position where it can engage with the locking portion 20. When the pulling force of the terminal portion 25 is released in this state, the engaging member 30 moves laterally and returns to the locking claw 3.
1 is engaged and fixed to the locking part 20, and the terminal part 25 is fixed to the frame 2.

Therefore, in this structure, when the wire 28 is rotated by pulling the end portion 25, the plurality of engaging members 30 at the pulled end portion 25 are connected to the wire 28.
Since they are engaged at the same time by the rotation of , the engagement work at each end portion 25 can be easily completed only once. Moreover, after the engagement and fixation, when a person or the like sits on the seat cushion 10, the end portion 25 of the trim cover 14 is pulled, and the engagement between the locking pawl 31 and the locking portion 20 is further strengthened, so it is sure to be secure. can maintain the engagement and fixation.

In addition, in the above embodiment, each terminal portion 25 has a bag-shaped portion 2.
6 is provided, and the wire 28 is rotatably supported by the bag-like part 26. However, the wire 28 is not provided with the bag-like part 26, and the wire 28 is attached to a synthetic resin member 32, as shown in FIG. is held rotatably,
A structure may be adopted in which this member 32 is fixed to each terminal portion 25. Further, the number of engaging members 30 provided on the wire 28 is set as necessary.

<<Effects of the Invention>> As is clear from the above description, according to the present invention, when each end portion is pulled once to transfer the wire, the engaging member is engaged with the locking portion of the frame. Therefore, even if a plurality of engagement members are provided at each end portion, the plurality of engagement members can be engaged and fixed at the same time, improving work efficiency. Moreover, since it is only necessary to strongly pull each end portion once, the burden on the operator is reduced and work efficiency is improved.
