Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention mainly relates to improvement of a seat back mounted on a front side of an automobile.

[0002]

[Prior Art]

 Conventionally, in the case of seat backs for automobiles, the cushion pad that is assembled to the seat back frame is covered with the back cover-shaped seat skin, and is fixed to the seat back frame in a position corresponding to the back skin removal part of the seat skin. There is one that gives a high-class feeling by attaching a backboard.

The backboard assembled to the seat back has a large weight, and it is desired to omit the mounting because it takes time and effort to mount and fix it on the seat back frame. However, simply removing the backboard and encapsulating the entire cushioning pad with only the bag-shaped seat skin will result in an extremely cheesy appearance with no crispness or texture. Even if a bead or the like is sewn on the back side of the seat skin according to the contour shape of the backboard, the sharpness and texture are still lacking, and a high-class feeling cannot be produced.

[0004]

[Problems to be solved by the device]

 It is an object of the present invention to provide a seat back which has been improved so as to be easily assembled by omitting a separate attachment of a backboard and to have a high-class feeling such as having a backboard.

[0005]

[Means for Solving the Problems]

 In the seat back according to the present invention, a back board part having a frame-shaped rising part is integrally formed on the back side of the seat back frame, the cushion pad is assembled to the seat back frame, and the seat pad is seated together with the cushion pad. The back frame is covered with a dorsal sheet-like skin, and the edges of the back and back skins are wrapped around and fastened to the rising edge of the backboard to secure the backboard. It is configured by encapsulating the part.

[0006]

[Action]

 In this seat back, the back board part is formed integrally with the seat back frame, and the frame edge where the end of the back and back skin is wound and fixed is inserted into the back board part and fixed to fix the seat back Since the whole is encased together, the bolts and other fastening means required for mounting and fixing the backboard and the labor required for mounting are eliminated, facilitating assembly, and the back skin is made up of the seat skin by the rising width of the backboard. Since it has a higher step than the main body side, the back side of the seat back can be given a sharp texture to give a sense of luxury.

【Example】

 FIG. 1 shows an automobile seat back from the upper side, and the seat back is assembled from a seat back frame 1 using a frame structure in which a back board portion 2 is integrally resin-molded. The backboard portion 2 is formed so as to be continuous from the peripheral side surface of the seat back frame 1 to the rear side via a curved concave portion 2a, and to have a high rear surface portion 2c with a rising portion 2b from the curved concave portion 2a. Has been done. This frame structure can also be formed by integrating the backboard portion 2 with the seat back frame 1 using a relatively flexible material such as urethane, and at least is formed as a hollow body with the bottom side open. .

In order to assemble a seat back using this frame structure, the cushion pad 3 is assembled to the seat back frame 1, and the seat pad is formed into a three-dimensional shape with a side portion and a back upper portion from the seat surface side. The seat cover 4 and the cushion pad 3 are attached so as to be attached to the seat back frame 1. The seat cover 4 can be pre-deposited by integrally molding it with the cushion pad 3, and as shown in FIG. 2, the terminals around the spine can be fixed with tackers, C-rings, fastening means such as adhesive. It is attached to the seat back frame 1.

The backboard portion 2 exposed from the seat surface 4 is separately encapsulated with the back and back surface skin 5. The back-and-back skin 5 is stretched and held by the edge frame 6 by winding and fixing the back end around the edge frame 6 made of a frame plate or a frame wire member. The back and back skin 5 is attached to the backboard portion 2 by fitting the edge frame 6 to the rising portion 2b of the backboard portion 2 and fixing and fixing the circumference of the edge frame 6 with a clip or a bonding fastener. ing. FIG. 4 shows a case where the clip 7 is fastened and fixed, and the clip 7 is fitted from inside the edge frame 6 into the curved concave portion 2a of the backboard part 2 into which the edge frame 6 is fitted. The terminal of 5 is stopped.

In the seat back configured as described above, since the back board portion 2 is integrally provided in advance at the stage of forming the seat back frame 1, it is possible to use a fastening means such as a bolt necessary for fastening the board or an assembly process. The time and effort required can be saved. The backboard portion 2 is covered with the back and back skin 5 by fitting and fastening the edge frame 6 for holding the back and back skin 5 on the rising portion 2b of the backboard portion 2. It does not take time to attach the to the backboard part 2. Also, since the back and back skin 5 is positioned higher than the skin surface of the seat skin 4 which is wound and fastened on the back side of the backboard portion 2 at the rising portion 2b of the backboard portion 2, it is a separate backpack. By giving the appearance as if the board is attached, the texture and texture can be added to the back side of the seat back, creating a high-class feeling.

[Effect of the device]

 As described above, according to the seat back according to the present invention, the seat back can be easily assembled, is lightweight, and has a high-class appearance.
