DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat back of an automobile seat, and more particularly, to a seat back structure in which a backrest and an armrest stored in a storage portion are arranged side by side on a back frame.

[0002]

2. Description of the Related Art A storage portion of a conventional seat back in which a backrest portion and an armrest stored in a storage portion when not in use are arranged on a back frame, a foam pad is supported on the back frame. Is covered with the epidermis.

[0003] An insert wire is buried in the above pad, this insert wire is locked on the back frame side, and the skin is attached to an insert wire provided separately from the insert wire.

[0004]

Therefore, in the conventional product, the pad is supported on the back frame, and the pad is covered with the outer skin to form the storage portion of the armrest. Cost.

[0005] This is because the pad has soft elasticity and is locally compressed by the adhesion of the skin.

In the case where the shape of the storage section is not accurately determined, the state in which the armrest is stored in the storage section is as follows.
The outer surface of the armrest did not match the outer surface of the backrest, and the appearance quality of the seat back was impaired.

Therefore, an object of the present invention is to eliminate such disadvantages of the conventional product.

[0008]

In order to achieve the above object, according to the present invention, the storage portion covers a panel supported by a back frame, and covers the panel and is integrally connected to a skin of a backrest portion. It is characterized by comprising a storage section skin for locking the terminal to the back frame side.

With the above configuration, since the panel is hard and has no elasticity, the storage portion is formed in a predetermined shape.

[0010] Further, a tilting portion is provided at the lower portion of the backrest so as to be tiltably connected to the back frame, and the armrest is rotatably mounted on the movable frame of the tilting portion in a cantilever manner so as to be rotatable. Can be simplified, and the shape of the storage section can be more accurately determined.

Further, by providing a hook portion for hooking on a locking wire fixed to the back frame on the back abutment side of the panel, the panel can be easily and accurately attached to the back frame side.

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 back frame (2), a panel (1), and an armrest (3) of a seatback with an armrest according to the present invention.

The back frame (2) is formed by welding a pipe assembled in a frame shape to a metal plate (27). The back frame (2) is attached to hinge brackets (50) (51) fixed to a vehicle body. It is pivoted forward. In the figure, (29A) is an operation knob mounting portion for unlocking, (2)
Reference numeral 9) denotes a housing portion for housing a latch engaged with a striker (not shown) of the vehicle body. By operating an operation knob, the latch engaged with the striker is released from the striker and unlocked, and the back frame ( 2) is configured to be able to fall forward.

The upper frame portion (25A), the right frame portion (25B) of the back frame (2),
Lower frame part (25C), left frame part (25
D) and the vertical support frame portion (25F) are each formed of a pipe, and these are welded to the inside of a metal plate (27) having flanges (27E).

The vertical support frame portion (25F) and the left frame portion (25D) of the back frame (2).
The movable frame (26A)
The upper portions of (26B), (26C) and (26D) are pivotally attached by hinge brackets (28C) and (28C) so as to be tiltable.

Brackets (28A) and (28B) are welded to the lower left and right sides of the movable frame (26A)... An arm having one end connected to the bracket (28A) (28B) to a seat cushion (not shown). The other end of the movable frame (26A) is tilted by pushing the lower part of the movable frame (26A) forward by the arm being pulled by the seat cushion advancing by the seat cushion slide device (not shown). It is configured as follows.

In the drawing, (26E) and (26F) are the tilting portions (1C) (1) shown in FIG. 3 integrally with the movable frame (26A).
The wire for pad support of E) is shown.

As shown in FIG. 2, the panel (1) is made of synthetic resin to have a slightly larger outer shape than the armrest (3), and reinforcing ribs (13A) arranged vertically and horizontally on the back side.
(13B), a hook portion (11), a protrusion (12), a flange (14), and an engaging portion (13A ') of the back frame provided in the vertical direction.

The above-mentioned hook portion (11) comprises a pair of left and right hook-shaped pieces (11A) and (11B) having elasticity in the left-right direction, and these hook-shaped pieces (11A) and (11B) are locked at the center. It is formed so that it may face so that a storage part (11C) may be formed.

The armrest (3) is connected to the bracket (2).
A support shaft (30) is rotatably inserted into a through hole (23) provided in the upper part of 8A), and is used by a stopper shaft (31) inserted into an arc-shaped long hole (24) provided in a bracket (28A). State and non-use state are maintained. In the figure (30
A) shows a protective cap provided at the end of the support shaft (30). Therefore, the armrest (3) is, as shown in FIG.
Cantilever movable frame (26B) with support shaft (30)
Supported on the side. In FIG. 5, (32) indicates a foam pad of the armrest (3), and (33) indicates the same epidermis.

The vertical support frame portion (2) of the back frame
On one side of 5F), a trim wire (22) and a locking wire (21) for locking the locking portion (11) of the panel (1) are welded.

In FIG. 1, (A) shows a panel (1).
(B) is a fixing part (1B) of the backrest shown in FIG.
(C) is a support portion for supporting the tilting portion (1C) of the backrest shown in FIG. 3, and is formed by the movable frame portions (26A).

(D) is a fixed projection (1D) provided above the storage section (1A) of the armrest (3) shown in FIG.
(E) is located below the storage section (1A), and rotates with the movable frame (26A).
Are respectively shown.

FIG. 3 shows a state of use of the armrest (3). The armrest (3) is, as described above, tilted (1C).
Since the movable frame (26A) is supported in a cantilever manner on the side of the movable frame (26A), the movable frame (26A) moves forward with the tilting of the tilting portion (1C), thereby improving usability.

The armrest (3) is stored in the storage section (1A) by rotating, and in this stored state, is configured to be used as a part of the backrest together with the movable section (1E).

As shown in FIGS. 4 and 5, the storage section (1A) is supported by the back frame (25D) on one side and the panel (1) on the other side hooked on the locking wire (21). And a storage section skin (41) for covering the panel (1).

The skin (41) for the storage part is joined to the skin (61) of the fixing part (1B) of the backrest and the skin (51) of the tilting part (1C). A hook (41B) made of resin is sewn, and the hook (41B) is engaged with the locking projection (12) of the panel (1). (1C) is fixed.

Then, the resin plate (41A) sewn to the end of the storage portion skin (41) is inserted and locked in the engagement groove provided in the metal plate (27) of the back frame, thereby storing the storage plate. The terminal of the epidermis (41) is fixed.

The side of the storage section (1A) in the skin (51) of the tilting section (1C) is hooked to a trim wire (22) by a hook.

Thus, since both ends of the storage section skin (41) covering the panel (1) are fixed as described above, the storage section (1A) stretches the panel (1) without wrinkles or bulges. Is established.

[0031]

According to the first aspect of the present invention, since the storage portion for storing the armrest is integrally connected to the panel and the skin of the backrest portion, and is constituted by the storage portion skin for covering the panel. , The shape of the storage section can be accurately determined,
The appearance quality of the seat back with the armrest storage section can be improved. In addition, pads unlike conventional products are not required, and can be provided at low cost.

According to the second aspect of the present invention, since the armrest is supported in a cantilever manner, the storage section can be easily and accurately formed into a predetermined shape.

According to the third aspect of the present invention, it is possible to easily and accurately perform the panel assembling operation, and to provide a seat back having further excellent appearance quality.
