Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a hanging structure applied to shape a hanging pattern on a seat surface portion of a seat back, and is particularly suitable for shaping a hanging pattern near a lower portion of the seat surface portion. The present invention relates to a structure for suspending a seat back seat surface portion.

[0002]

[Prior Art]

 In some automobile seats, for example, a hanging pattern 1 as shown in FIG. 2 is shaped along the boundary line between the seat surface portion 2a of the seat back 2 and the bank portion 2b.

Conventionally, in order to shape the hanging pattern 1, as shown in FIG. 3, a plurality of bracket plates 4 are welded and fixed to the main frame of the seat frame 3 and then, as shown in FIG. As shown in the figure, it is usually carried out by suspending suspending springs 7a and 7b, which are required to be suspended vertically and horizontally, between suspending cords 6a and 6b mounted inside the front part of the seat skin 5.

It is desired to reduce the weight of a vehicle seat, and from this viewpoint, the structure of each part of the seat was examined. As a result, the bracket plate 4 was made of metal and was heavy, and It was found that it could be replaced by other members due to the structure of the grate, and that welding would have to be applied for its attachment, which made the work time-consuming and costly.

[0005]

[Problems to be solved by the device]

 From the above viewpoint, the present invention reduces the number of parts by omitting the bracket plate, contributes to the weight reduction of the entire sheet, simplifies the assembling workability, and reduces the cost. It is an object to provide an embedded structure.

[0006]

[Means for Solving the Problems]

 In the hanging structure of the seat back seat surface according to the present invention, a hanging cord attached to the front inside of the seat skin according to the hanging pattern formed on the seat back surface portion of the seat back. The suspension spring is suspended via a cushion pad held by the seat back frame between the seat and the trim plate attached to the rear end of the seat skin for fastening the end of the seat skin. It is composed by.

[0007]

[Action]

 In this structure for suspending the seat back seat surface, the suspending springs are suspended on the front side and the rear side of the seat skin through the cushion pad held by the seat back frame, so that the suspending pattern is formed. In addition to being able to hold the shape of the seat in a predetermined shape, the number of parts can be reduced by also using the trim plate for fastening the end of the seat skin as the suspension of the suspension spring, thus reducing the weight of the entire seat. It is possible to reduce the manufacturing cost and the assembly process.

【Example】

 FIG. 1 shows a structure for suspending a seat back seat surface portion which can be placed on the lower side of the seat back. In the figure, 10 is a seat skin, 11 is a seat back frame, 12 is a cushion pad, and 13a. , 13b are suspending cords, 14 is a trim plate for attaching a seat skin terminal, and 15a, 15b are suspending springs.

The hanging cords 13a and 13b are arranged inside the front portion 10a of the seat skin 10 according to a hanging pattern formed on the seat surface side of the seat back similar to that shown in FIG. Is attached to. When attaching the sheet, the sheet cover 10 can be sewn together with the sewing allowance when the sheet cover 10 is sewn into a three-dimensional bag.

The trim plate 14 for fixing the end of the seat epidermis is attached to the end of the seat epidermis 10 wound from the lower side of the cushion pad 12 to the back side and the upper side of the cushion pad 12 to the back side. The seat surface 10 is attached to the cushion pad 12 by connecting the end of the rear part 10b of the seat surface 10 to the cushion pad 12. The trim plate 14 is made of a horizontally long resin having a predetermined length, and is attached by sewing on the inside of the end of the seat skin 10 that is wound from the lower side of the cushion pad 12 to the back side. There is. The trim plate 14 is integrally formed with a hook-shaped hooking portion 14a for fitting and fixing the end of the rear portion 10b of the seat skin 10, and a rigid resin attached to the end of the rear portion 10b. By fitting together with the plate 16 into the hooking portion 14a of the trim plate 14, both ends of the seat surface 10 are connected. The trim plate 14 may be integrally formed by raising a necessary number of projections 14b having opening holes for retaining one end of the hanging springs 15a and 15b upward at desired intervals.

The cushion pad 12 is formed of a foamed resin such as urethane, and is attached to the seat back frame 11 so as to be maintained in a predetermined standing state. The cushion pad 12 is provided with through holes 11a necessary for suspending the suspension springs 15a and 15b in the front portion 10a and the rear portion 10b of the seat skin 10, and also, the seat back frame 11 and the seat skin terminal stop wear. A relatively hard support block 11b made of urethane or the like is integrally mounted so as to be located between the trim plate 14 and the trim plate 14.

In order to assemble the suspension structure of the seat back seating surface portion from these parts, the cushion pad 12 held by the seat back frame 11 is covered with the bag-shaped seat skin 10, and then the terminals of the seat skin 10 are connected and sealed. Before stopping, hook each spring end of the hanging springs 15a, 15b through the through hole 11b of the cushion pad 12 from the hanging cords 13a, 13b so as to suspend it on the trim plate 14 for fastening the seat skin terminal. Just do it. At this time, if the protrusion 14b having the above-described stop hole is provided on the trim plate 14, the spring end can be easily hooked to the trim plate 14. After the suspension structure is assembled, the end of the rear portion 10b of the seat skin 10 is fitted and fixed to the hooking portion 14a of the trim plate 14, so that the entire seat can be assembled.

[0013]

As described above, according to the suspending structure of the seat back seat surface portion according to the present invention, the trim plate for fastening the seat skin terminal is configured as a member for locking one spring end of the suspending spring. As a result, it is possible to reduce the number of parts required to lock the spring end and reduce the number of parts, resulting in weight reduction and improvement in assembly workability as well as cost reduction. Further, the suspension line shaped on the seat surface portion of the seat back can also be shaped and maintained in a predetermined pattern by suspending the suspension spring on the front portion and the rear portion of the seat skin through the cushion pad.
