Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a trim cover for a vehicle seat, and more particularly to a structure that includes a strip-shaped pulling member along the covering direction of the trim cover.

Generally, for vehicle seats, a molded cushioning material made of synthetic resin is attached to the frame, and a trim cover with a designed structure is placed over this cushioning material. If you just leave it uncovered,
The trim cover lifts up from the cushioning material, and the decorative design that can be formed on the seating surface cannot be effectively exhibited.

For this reason, a pull member is provided inside the trim cover, and when the trim cover is put on, the pull member is housed in the cushioning material and is clipped to the wavy spring passed between the frames.

By the way, the trim cover for the seat back is sewn into a bag shape with an opening on the lower end side of the seed back, and it has to be covered from the top of the seat back after being turned over, so the drawing member cannot be made into a line-drawing configuration. It has no choice but to have a pull configuration.

For this reason, the trim cover is only attracted locally, and if the seating surface of the cushioning material is formed into an uneven surface to improve the holding ability of the seating surface, the pulling force will not be uniform and the appearance will deteriorate. It often gets significantly worse.

In order to solve the above-mentioned drawbacks, the present invention adds a strip-shaped pulling member to the inside of the trim cover in the vertical direction along the covering direction of the trim cover, and a notch or The present invention provides a trim cover that can be fitted with a trim cover in the same manner as in the past by forming a notch, and can have a line-drawing configuration.

Hereinafter, details of embodiments of the trim cover according to the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the process of covering the seat back of an automobile seat with the trim cover of the present invention. In this seat, the seat back C is attached to the rear of the seat cushion D by the stay B extending from the frame A. Two insertion grooves F are formed in the seating surface of the cushioning material E attached to the frame A of the seat cushion C at a predetermined distance from each other in the left and right directions.

A plurality of mounting holes G are drilled in these insertion grooves F at predetermined intervals in the vertical direction, and the bottom of each of these mounting holes G has a hole horizontally attached to the frame A as shown in FIG. A part of the wavy spring H that is suspended and constitutes the latching member is exposed.

On the other hand, the trim cover 1 is sewn into a bag-like shape with an opening at the lower end of the seat back C, and on the back side of the seating surface 2 of the trim cover 1, two strip-shaped pulling members 3 are provided in the insertion grooves F, respectively. It is sewn in the corresponding position with sewing thread 4.

These pulling members 3 are made of synthetic resin material,
The substrate 3a on the side to be sewn onto the seating surface 2 is made of a soft material.

Through holes 5, 5... are bored in this soft substrate 3a at positions corresponding to the mounting holes G, respectively, and holes 5, 5, . V-shaped notches 6, 6, . . .

Due to the presence of the notches 6, 6, . . . , the substrate 3a can be bent relatively easily in the longitudinal direction from both sides of each notch 6.

Furthermore, a reinforcing member 8 made of hard synthetic resin is integrally attached to each longitudinal edge of the substrate 3a located between the V-shaped notches 6, 6, . . . .

This reinforcing member 8 is formed into a belt shape having a U-shape in cross section, and is fixed so as to sandwich the leading edge of the substrate 3a from both sides.

According to the embodiment configured as described above, after the trim cover 1 is sewn, the trim cover 1 is turned over as in the conventional case and is placed over the seat back C from the top.

That is, as shown in FIG. 3, with the opening side of the flipped trim cover 1 facing upward, the side circumferential portion 1b of the trim cover 1 is sequentially pushed downward while pressing the top portion 1a of the dead end against the top Ca of the seat back C. Slide it down and cover it.

At this time, the pulling member 3 is pushed into the insertion groove F, and since the pulling member 3 is formed with a notch 6, the uppermost through hole 5 is positioned in the uppermost mounting hole G. In this state, the pulling member 3 is folded in half in the opposite direction across the notch 6, so that the work of putting the trim cover 1 on is not hindered in any way.

After the clip I is hooked to the wavy spring H and the through hole 5 by the meeting of the uppermost through hole 5 and the mounting hole G, The member 3 is pushed into the insertion groove F in the same manner as described above, and the clip I is sequentially latched to the through hole 5 and the wavy spring H.

Finally, the end pieces extending before and after the opening 1a of the trim cover 1 are clipped to the lower end of the seat back C in an overlapping state, thereby completing the work of putting the trim cover 1 on.

FIG. 4 is a sectional view of the other side corresponding to FIG. 3, and the same members as those in the embodiment described above are given the same reference numerals and detailed description thereof will be omitted.

A pulling member 3A corresponding to the pulling member 3 of the above embodiment includes a soft strip-shaped substrate 3a and a strip-shaped reinforcing member 7 with a U-shaped cross section that is integrally attached to the tip edge of the substrate 3a. A diagonal cut 8 is formed in the vicinity of 5 from the distal end of the pulling member 3 toward the proximal end.

Therefore, in this embodiment, when the pull member 3A is folded back from the notch 8 in the opposite direction while the trim cover 1 is covered, this folded portion is inserted into the through hole 5 as shown in the fourth figure.
Since the clip I is located higher than the clip I, the clip I can be easily latched.

In each of the embodiments described above, the trim cover of a seat back is illustrated, but the present invention is not limited thereto, and can be similarly applied to a trim cover of a seat cushion.

That is, as shown in FIGS. 5 and 6, the seat cushion D has an insert II F B extending in the front-back direction of the seat cushion D (the direction in which the trim cover is placed) on the seating surface of the cushioning material EB. It is engraved and the trim cover I
A strip-shaped pulling member 3B is attached to the back surface of B. The pull member 3B is fitted into the insertion groove F8 and is latched to the latching member HB with a clip (not shown).

This pulling member 3B has notches 6B or notches between the through holes 5B of the clip as in the previous embodiment.
It is engraved from the tip to the base.

Therefore, when covering the cushioning material EB with the trim cover IB from the rear to the front, the pulling member 3B is bent and clipped from the notch 6B or notch in the same manner as in the above embodiment, and the trim cover IB is placed on the cushioning material EB. covered.

In FIG. 6, reference numeral J denotes a strip-shaped horizontal pulling member stretched laterally at approximately the center of the seating surface of the seat cushion D, and through-holes K are bored at both left and right ends of the horizontal pulling member J. ing.

This horizontal pulling member J is attached to the trim cover IB as shown in FIG.
When the vertical pulling member 3B is folded back at the notch 6B, the horizontal pulling hook embedded in the buffer material EB is clipped to the member through the through hole K.

As explained above, according to the present invention, a notch or notch is formed in the strip-like member attached in the vertical direction of the trim cover at each upper and lower space to be latched. The member can be easily folded back.

Therefore, even if a strip-shaped pulling member is provided along the direction in which the trim cover is covered, the work of putting the trim cover on can be performed in the same manner as in the past, and a trim cover that can have a drawing structure similar to that of steel wire can be provided.
