Abstract

PURPOSE:To decrease the number of parts and to improve workability by covering a frame and a seat pad with a sheet cover in the state of mounting the seat pad on this frame, setting a core material at the end and detaining clips to clip detaining parts. CONSTITUTION:Screws 33 are passed through screw through-holes 31 of a rear surface board 30 and are screwed into the screw holes 3a of the frame 3 at the time of mounting the seat cover 7, by which the rear surface board 30 is screwed to the frame 3. The frame pad 6 is then mounted at the frame 3 by inserting the frame 3 into its recessed part 6a. The seat pad 6 and the frame 3 are covered and compressed by the seat cover 7 and the core material 20A is set at the rear surface board 30 in the parallel state to face the board from behind. The seat parts 22 of the respective clips 20 are successively pressed to the peripheral surfaces of long holes 32 in the tense state of the seat cover 7, by which a head part 21 is pressed and detained. As a result, the seat cover 7 is mounted at the frame 3.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable type in which a rear board is attached to a frame whose lower end portion is hinged so as to be tilted forward, a seat pad is mounted from the front, and a seat cover is covered from the front. The present invention relates to a seat cover mounting structure for a seat back.

[0002]

2. Description of the Related Art A seat cover mounting structure of this type is applied to, for example, a vehicle seat in which a seat back 2 is tilted forward on a seat 1 as shown in FIG. FIG. 3 shows the detailed structure. Reference numeral 3 denotes a substantially rectangular frame which can be tilted forward by being hinged to a hinge bracket 5 whose lower end is attached to the floor, and serves as a skeleton of the seat back 2. Soft resin plate-shaped core members 7 a and 7 b are sewn to the free ends of the upper surface of the seat cover 7 and the back surfaces of the free ends of both side surfaces. A panel 4 is welded to the rear surface of the frame 3, and this panel is welded to an upper end portion of a rear board 8 to which a floor carpet 9 is attached and a U-shaped insertion bracket 4a for engaging a core material 7a. The insertion brackets 4b on both sides for engaging the core material 7b are press-molded. Further, a hook 4c for locking a ring (not shown) loosely fitted to the wire attached to the free end of the lower surface of the seat cover 7 is formed in the lower portion of this panel.

When the seat cover 7 is attached, the seat pad 6 is attached to the frame 3 and the frame 3 is attached to the recess 6a.
The seat cover 7 and the core member 7a is engaged with the bracket 4a, the core member 7b is engaged with the bracket 4b, and the lower surface of the seat cover 7 is engaged with the hook 4c. Stop it. Next, as shown in FIG. 4, the upper end portion of the back board 8 is engaged with the core material 7a to cover the bracket 4b. In addition, clip 1
0 through the mounting holes 11 of the rear board 8 to the panel 4
It is attached to the mounting hole 12 of. The seat back 2 with the seat cover 7 attached in this manner is a retractable type in which the frame 3 is screwed to the hinge bracket 5 fixed to the floor.

[0004]

However, in such a mounting structure, it is necessary to insert the core material of the seat cover, and the number of parts is increased.

In view of the above points, an object of the present invention is to provide a seat cover mounting structure for a retractable seat back which can reduce the number of parts and improve workability.

[0006]

In order to achieve this object, the present invention attaches a rear board to a substantially rectangular frame whose lower end portion is hinged to be able to tilt forward and mounts a seat pad from the front. , In a seat cover mounting structure of a retractable seat back configured by being covered with a seat cover from the front side, the front face is separated from the upper and lower faces and both side faces of the rectangular seat cover and extended from each other. On the back surface of the free end, attach a resin-made plate-shaped core material integrally formed with a plurality of clips, and at the top and bottom and both ends of the back board, clip locking parts that lock the clips. By forming, by mounting the seat pad by screwing the back board to the frame, cover the seat pad and the frame with the seat cover,
Further, it is characterized in that the core member is set at the end portion and the clip is locked to the clip locking portion.

[0007]

The seat pad and the frame are covered with the seat cover from the front while the back board is screwed to the frame and the seat pad is attached. Next, the free ends cover the upper and lower ends of the back board from behind, and the core material on the back surface is set at the ends to lock the clip to the clip locking portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A seat cover mounting structure for a retractable seat back according to an embodiment of the present invention will be described with reference to FIGS. The same reference numerals are used for the same or equivalent parts as those described above.

A plurality of clips 20 are provided on the rear surface of the free end portion, which is separated from the upper and lower surfaces and the both side surfaces of the rectangular seat cover 7 so as to surround the seat pad 6 on the front surface. 20A of resin-made plate-shaped core materials integrally formed with each are sewn. Clip 20
Is a rectangular shape having a head portion 21 protruding inward in the orthogonal direction from the tip end portion of the plate-shaped core material 20A, bulging in an inverted triangular shape at the tip end portion, and having a long side in the longitudinal direction of the core material 20A. Formed as a plate. A seat portion 22 is similarly formed integrally with the head portion 21 so as to project closer to the base end than the head portion 21. Three such clips 20 are intermittently formed on each core member 20A.

At the upper and lower ends of the rear board 30, screw through holes 31 for screwing into the screw holes 3a of the substantially rectangular frame 3 are formed, and the upper end of the floor carpet 9 is attached. Further, elongated holes 32 as clip engaging portions corresponding to the cross-sectional shape of the clip 20 are formed at the upper and lower ends of the rear board 30.

When the seat cover 7 is attached, the rear board 30 is fixed to the frame 3 by screwing the screw through hole 31 of the rear board 30 into the screw hole 3a of the frame 3 through the screw 33. Next, the seat pad 6 is mounted on the frame 3 by inserting the frame 3 into the recess 6a. Further, the seat cover 7 covers and compresses the seat pad 6 and the frame 3, and the core material 20A is set on the rear board 30 from the rear side in parallel and face-to-face with each other. The seat portion 22 is applied to the peripheral surface of the elongated hole 32, and the head portion 21 is pressed and locked. As a result, the back board 3 is formed by the head 21 and the seat 22.
0 is sandwiched, and the area of the slot 32 is covered by the free end of the seat cover 7, and the seat cover 7 is attached to the frame 3 in the state shown in FIG.

[0012]

According to the invention of claim 1, in a retractable seat back in which the appearance is particularly problematic, it is locked in the process of setting the core material provided with the clip toward the rear board from behind. The seat cover can be installed easily. Therefore, not only is workability improved,
The number of attached parts can be reduced and the weight can be reduced, which is advantageous in terms of cost.

According to the second aspect of the present invention, since the clip is formed as a rectangular plate elongated in the core material direction, it can be securely attached with a small number of clips, and the attachment portion is also seated via the core material. It is covered with a cover and looks good.
