Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seat back (back portion) of an automobile seat (seat), and more specifically, to a foam pad for a center-folded seat back in which an upper portion of the seat back is formed to be tiltable in a front-back direction with respect to a lower portion. Regarding the structure.

[0002]

[Prior Art]

 In the conventional center-folded seat back, a lower frame that constitutes the lower seat back is connected to an upper frame that constitutes the upper seat back so as to be tiltable in the front-rear direction, and the upper and lower frames are connected to the upper seat back. In some cases, a foam pad composed of an upper pad that constitutes the upper pad and a lower pad that constitutes the lower seat back integrally with the upper pad is covered with a trim cover.

[0003]

[Problems to be solved by the device]

 In this conventional product, the pad of the upper seat back that tilts forward and backward and the pad of the lower seat back are integrally foam-molded. Then, the upper and lower pads are molded with a foam material such as urethane foam having a certain rigidity. Therefore, when the upper frame is tilted forward by the reclining device, the upper pad and the lower pad are integrally rigid, so that the upper pad is difficult to move (bend) by the upper frame. Therefore, the operability of the forward leaning operation of the upper seat back is poor, and wrinkles and sagging due to pad deformation occur at the boundary between the seating surfaces of the upper seat back and the lower seat back, and the appearance quality of the seat back is impaired. There was a problem. Therefore, the present invention aims to improve the operability of the upper seat back and prevent wrinkles and slack from occurring in the seat back when the upper seat back is tilted forward.

[0004]

Means for Solving the Problems The present invention to achieve the above object is to provide a foam pad in which an upper pad of an upper seat back and a lower pad of a lower seat back are integrated with each other. A bent portion that integrally connects the upper and lower pads is provided in the center of the seating portion between the lower pad and a slit that separates the upper pad and the lower pad from each other in the lateral direction of this bent portion. Is.

[0005]

[Action]

 Since the upper pad and the lower pad are divided by the slits except for the center of the seating portion, the bendability in the front-back direction of the upper pad is improved. Therefore, the upper frame easily tilts the upper pad forward.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a center-folded seat back (SB), which is composed of a lower seat back (A) and an upper seat back (B) connected to the lower seat back (B) so as to be tiltable in the arrow direction by a reclining device. The lower seat back (A) is tiltably connected to the seat cushion (SC) by a reclining device. In the figure, (HR) indicates a headrest attached to the upper seat back (B).

FIG. 2 shows a pad (P) made of a foam body (urethane foam, etc.) of a seat back (SB) according to the present invention, and the pad (P) is an upper part that constitutes the upper seat back (B). It is composed of a pad (1) and a lower pad (2) constituting a lower seat back (A), and the lower pads (1) and (2) are seated portions (2 1) and (22) which are front surfaces. (11) and (12) are integrally connected at the bent portion (3), and are separated by slits (41) and (42) on the left and right sides of the bent portion (3).

The seating portions (21), (22) and (22) of the upper pad (1) and the lower pad (2) have their left and right parts projecting forward with respect to the central portions (11) and (21), and the upper half of the body of the seated person. Is molded to hold the. In the figure, (12), (12), (22) and (22) are raised portions, and (13) and (23) are side portions of the pad (P).

As shown in FIGS. 3 and 4, the front surface of the bent portion (3) is formed with a groove (32), so that the bent portion (3) has a thin shape and is shown in the drawing. An insert wire (31) is embedded inside the bent portion (3). The slits (41) (42) are formed between the left and right ridges (12) (12), (22) (22) of the upper pad (1) and the lower pad (2) and the side parts (13), (23). It is provided in the lateral direction. Therefore, the upper pad (1) and the lower pad (2) are separated from each other except the bent portion (3), and the bent portion (3) is formed in a thin-walled shape. To the upper pad (1) is easy to fold forward.

5 and 6 show a center-folded seat back (SB) using the above pad (P), in which (5) is a lower frame constituting the lower seat back (B), (6) Indicates an upper frame connected to the lower frame (5) by a reclining device (not shown) so as to be tiltable in the front-rear direction, and the lower frames (5) and (6) are covered with the pad (P). The pad (P) is covered with the trim cover (7) to form a center-folded seat back (SB). The above-mentioned trim cover (7) has a conventionally well-known structure. The upper and lower members (71, 72) are joined to each other, and the suspending member (73) is integrally formed on the back side of the joined portion. The trim cover (7) is suspended by binding, and inserting the suspending material (73) into the groove (32) and binding to the insert wire (31) of the bent portion (3) with a hog ring. .. In addition, the other part of the trim cover (7) to be joined is inserted into the slit (42). The trim cover (7) may be adhered to the surface of the pad (2) with an adhesive without using the hanging method as described above.

[0011]

EFFECTS OF THE INVENTION According to the present invention, the upper pad and the lower pad are integrally connected by the bending portion at the center of the seating portion, and the other portions are separated, so that the bending of the upper pad in the front-back direction is performed. It becomes very good. Therefore, since the upper frame covered with the upper pad is smoothly rotated in the front-back direction, the operability of the forward leaning operation in the upper seat back is improved, and when the upper seat back is leaned forward, The upper pad itself does not deform, and there are no wrinkles or slacks between the upper seat back and the lower seat back that impair the appearance of the seat back.
