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 at the rear ends of the left and right sides between the lower pad and a slit that separates the upper pad and the lower pad is provided in the front direction of this bent portion. It will be.

[0005]

[Action]

 Since the upper pad and the lower pad are divided by slits except for the rear ends of the side portions, the bendability of the upper pad in the front-rear direction 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 upper and lower pads (1) and (2) are provided on both left and right side portions (11) (11) (21). The rear end of (21) is integrally connected by the bent portions (3) and (3), and is divided by the slit (4) in front of the bent portion (3).

The upper pad (1) and the lower pad (2) are composed of seating portions (12) and (22) and left and right side portions (11), (11), (21) and (21), and the upper pad (1) A back and back portion (13) is integrally formed on the back, and is molded so as to enclose upper and lower frames (5) and (6) which will be described later. A slit (4) is formed in front of the bent portions (3) and (3) as shown in FIGS. Therefore, the upper pad (1) and the lower pad (2) are completely separated except for the bent portions (3) and (3), so that the upper pad (1) is separated from the bent portion (3). Is easy to bend forward.

FIG. 6 shows a center-folded seat back (SB) used with the above pad (P). In the figure, (5) is a lower frame constituting the lower seat back (B), and (6) is a lower flap. Shown in the frame (5) are upper frames connected 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 pads (P). The pad (P) is covered with a 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. By sewing, the suspending member (73) is inserted into the slit (4) between the seating portions (12) and (22), and is attached to the trim wire (51) of the lower frame (5) with a hog ring. Suspend the trim cover (7). In addition, the other joining points of the trim cover (7) are inserted into the slit (4). 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.

[0010]

[Effect of the device]

 According to the present invention, the upper pad and the lower pad are integrally connected at the rear end bent portions on both sides, and the other portions are separated, so that the upper pad has excellent bendability in the front-back direction. become. Therefore, since the upper frame covered with the upper pad can be smoothly rotated in the front-back direction, the operability of the forward leaning operation of the upper seat back is improved and the upper seat back is tilted forward. The pad itself does not deform, and there are no wrinkles or slacks between the upper seat back and the lower seat back that deteriorate the appearance of the seat back.
