Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to an automobile seat (seat).
More specifically, the present invention relates to a back-side structure of a center-folded seat back in which an upper portion of the seat back is formed to be tiltable in a front-rear direction with respect to a lower portion of the seat back.

[0002]

2. Description of the Related Art In a conventional folded seatback, an upper frame constituting an upper seatback is connected to a lower frame constituting a lower seatback so as to be tiltable in a front-rear direction. There is a type in which an upper pad constituting the upper seat back and a lower pad constituting the lower seat back integrally with the upper pad are covered with a foam pad, which is covered with a trim cover.

[0003]

When the upper seat back is tilted forward, a gap is formed at the boundary between the upper seat back and the lower seat back on the back back side. Parts inside the seat back were visually perceived, and there was a problem with very poor appearance quality. In order to eliminate such inconvenience, there is a type in which a bellows-like shielding curtain is provided on the back side of the upper seat back and the lower seat back in a vertical direction for connecting the upper and lower seat backs.

[0004] However, the one using this shielding curtain,
When the back of the upper and lower seatbacks is covered with a trim cover, the upper and lower seatbacks can be sewn between the trim covers.However, when the backboard is attached to the back of the lower seatback, the lower There is a defect that sewing cannot be performed on the seat back side. Therefore, an object of the present invention is to prevent a gap from being generated on the back side of the upper seatback when the upper seatback is tilted forward without using the shielding curtain.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, a trim wire is fixed to the inside of a back board at an upper portion of a lower frame of the conventional product, and the trim wire is attached to the upper seat back. It is characterized in that a lower terminal of a trim cover constituting the back is attached.

[0006]

The trim cover that forms the back and back side of the upper seat back that tilts in the front-back direction is connected to the trim wire on the lower seat back side. Therefore, when the upper seat back is tilted forward, the upper seat back and the lower seat are tilted. There is no gap between the back and the back.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a state before the upper seat back (B) leans forward with respect to the lower seat back (A), and FIG. 2 shows a state where the upper seat back (B) leans forward. The horizontal rod (10) suspended on the upper part of the lower frame (a) so that the trim wire shown in (1) in the figure protrudes in the upper direction of the backboard (8) of the lower seat back (A).
It is fixed to. The lower frame (a) and the reclining devices (22) (2)
The structure of the upper frame (b), which is connected by 3) so as to be tiltable in the front-rear direction, is configured as shown in FIGS.

The illustrated lower frame (a) includes left and right side plates (13) and (14), a pipe horizontal rod (10) suspended above the side plates (13) and (14), and a side plate (13). )
It consists of brackets (15), (16) and the like welded upright from the top of (14).

The illustrated upper frame (b) comprises a main body (20) obtained by bending a pipe into a U-shape, and an upper rod (21) welded to the top of the main body (20). At both free ends of the body (20), mounting brackets (24)
(25) is fixed, and the left and right mounting brackets (2
4) and (25) are pivotally attached to the brackets (15) and (16) of the lower frame (a) so as to be rotatable in the front-rear direction, and are tilted to the upper and lower mounting brackets (24) and (25). Reclining device (22) (2)
3) is mounted, and both reclining devices (2)
2) (23) is connected by an interlocking shaft (26),
One reclining device (23) is a motor (M)
Operated by In the figure, (27) and (27) indicate the main body (2).
It is a stay insertion holder for the headrest fixed to 0).

The horizontal rod (10) of the lower frame (a) described above.
As shown in FIG. 4, a trim wire (1), a front wire (12), and a rear wire (11) are welded in parallel with the horizontal rod (10), respectively. ) (1
1) is bent in a U-shape. Therefore, the trim wire (1) is located inside the back board (8) mounted on the back of the lower seat back (A).

The frame structure shown in FIG. 3 is covered with foam pads (5) and (6) and trim wires (3) and (4), and a backboard (8) is provided on the back side of the lower frame (14). Is fixed. An L-shaped claw (61) is integrally fixed on the left and right inside the upper part of the backboard (8), and the claw (61) is inserted into the inside of the trim wire (1) and hooked. The upper part of the back board (8) is fixed to the lower frame (a) side.

The upper pad (5) and the lower pad (6) constituting the upper seat back (B) and the lower seat back (A) are integrally molded, and a slit (51) is provided on the seat side thereof. A hole is opened, and a joint portion of the trim cover (3) of the upper seat back (B) and the trim cover (4) of the lower seat back (A) is inserted into the slit (51). A hanging material (31) is integrally sewn on the back surface, and the hanging material (31) is
Are integrally joined to the trim wire (1) by a hog ring (72).

The rear side of the upper frame (b) is covered by a rear portion (50) of the upper pad (5), and a trim that covers the rear portion (50) and constitutes the back of the upper seat back (B). The lower end (30a) of the rear town (30) of the cover (3) is connected to the trim wire (1) by a hog ring (71). The front wire (1
2) Supports the inner surface of the upper pad (5) on the seating portion side, and the rear wire (12) supports the inner surface of the back portion (50) of the upper pad (5), thereby preventing deformation of the upper pad (5) due to external force. ing.

Thus, when the upper seat back (B) is tilted forward by the reclining device from the state shown in FIG. 1, the lower terminal of the rear gusset (30) in the trim cover (3) of the upper seat back (B). Since (30a) is fixed to the trim wire (1) on the lower seat back (A) side, as shown in FIG. 2, the rear portion (50) of the upper pad (5) is pulled by the tension of the rear gusset (30). Although pressed, there is no gap between the upper board (B) and the backboard (8) of the lower seat back (A).

[0015]

According to the present invention, the lower end of the trim cover that forms the back of the upper seat back is connected to the trim wire of the lower seat back. There is no gap at the boundary between the back of the seat back and the lower seat back. Therefore, since there is no need to separately mount the shielding curtain as in the above-described conventional product, the structure is simplified and the assembling property is improved.
