[Prior Art]

 2. Description of the Related Art Conventionally, a seat back shown in FIG. 6 is known as a seat back that is equipped in a passenger compartment of a vehicle such as a passenger car and functions as a backrest of a passenger. FIG. 6 is an enlarged perspective view showing a corner of a rear seat of a passenger compartment of a passenger car or the like. In the drawing, the seat back 1 is used as a backrest formed by molding a predetermined cushion material, for example. It is a thing. This seat back 1 is provided with a seat frame 2 in which, for example, steel wires are arranged in a grid pattern in an exposed state on the back side of the seat back 1 as a clue for structurally reinforcing the cushion material and fixing it to the vehicle side.

By the way, in order to fix the seat back 1 in the vehicle compartment, as shown in FIG. 7, the back side of the seat back 1 is opposed to the vehicle side fixing surface 3, and the seat back 1 is projected on the fixing surface 3. The upward hook 3a is used. That is, the seat back 1 is lifted slightly upward and then pressed against the vehicle-side fixed surface 3, and is lowered to move in the direction of arrow A, so that the horizontal frame 2b of the seat frame 2 is moved upward. A fixing structure is adopted in which the vertical frame 2a is screwed to the fixing surface 3 and is hooked to the fixing surface 3a.

[0004]

[Problems to be solved by the device]

 By the way, in the seat back 1, the horizontal frame 2b of the lattice-shaped seat frame 2 provided on the back surface of the seat back 1 is hooked on the upward hook 3a projecting from the vehicle body side fixing surface 3. Therefore, it is necessary to bring the seat back 1 to a position slightly above the fixed position in advance. For this reason, when fixing the seat back 1, it is necessary to temporarily lift the heavy seat back 1 to a position slightly above the fixed position, which is a difficult work. Further, for example, when the seat back 1 is attached to the rear seat of the passenger car as shown in FIG. 6, the roof side inner garnish 4 which is the interior material of the rear roof side provided inside the passenger car is used. Was getting in the way, causing the problem shown in Figure 8. That is, FIG. 8 is a schematic view showing the vicinity of the upper corner of the seat back of the rear seat of the passenger car from the front. In this area, the roof side inner garnish 4 overhangs toward the roof portion above it as shown. Is extended. Therefore, when the seat back 1 is fixed, when the seat back 1 is brought to a position slightly higher than the position where it should be fixed, the upper corner portion 1a of the seat back 1 has a roof side inner portion. Since it collides with the overhanging part of the garnish 4, it is impossible to perform the fixing work. Therefore, conventionally, the corners of the upper end of the seat back 1 are chamfered in an R shape so as to avoid collision with the roof side inner garnish 4 during fixing work. As shown in FIG. 8, it was moved down from the chain line position and moved to the fixed position shown by the solid line. However, since the seat back 1 fixed in this way has a chamfered upper corner portion 1a in advance, when the seat back is fixedly arranged at a predetermined position, a gap S is formed between the seat side 1 and the roof side inner garnish 4. The interior design is extremely unfavorable in determining the commercial value of passenger cars.

The present invention has been devised in view of the above problems, and provides a vehicle seat back which is easy to fix the seat back and which has an excellent appearance in the fixed state. The purpose is to

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a vehicle seat back according to the present invention is provided with a seat frame that extends vertically and horizontally in a lattice pattern on the back side of the seat back, and a seat frame that is vertically movable with respect to the horizontal frame of the seat frame. The movable frame is provided with a hooking portion, and the rear side of the seat back and the vehicle-side fixed surface are arranged so as to face each other, and the movable frame is advanced downward, so that the hooked portion of the movable frame is stopped. And a hooking portion provided on the vehicle-side fixing surface so as to lock and fix the vehicle.

[0007]

[Action]

 According to the above configuration, the seat frame is exposed on the back surface of the vehicle seat back, and the movable frame is provided which moves forward and backward with respect to the lateral frame of the seat frame. Therefore, only the movable frame is raised slightly, the back side of the seat back is pressed against the vehicle body side fixed surface, and the movable frame is lowered. As a result, the hooked portion provided on the movable frame descends and is hooked and fixed to the hooking portion formed on the vehicle body side fixing surface.

【Example】

 Hereinafter, a preferred embodiment to which the present invention is applied will be described in detail with reference to FIGS. FIG. 1 is a schematic perspective view showing a vehicle seat back according to this embodiment. In the drawings, a seat back 10 is arranged in a lattice pattern on the back side thereof as a clue for structurally reinforcing the seat back main body 11 which is a backrest of a vehicle seat and for fixing the seat back main body 11 to the vehicle side. The seat frame 12 is provided.

The seat back main body 11 is formed by molding a foam material of synthetic resin or the like into a shape suitable for a passenger's back, and in the embodiment shown in FIG. 1, the rear portion of the passenger car. An example formed for a seat is shown. The seat frame 12 is made of, for example, a durable steel wire rod and is exposed vertically and horizontally like a vertical frame 12a and a horizontal frame 12b on the back side of the seat back main body 11.

The above structure is similar to that of the conventional seat back, but in the present embodiment, the movable frame 13 as shown in the drawing is provided. The movable frame 13 is formed of, for example, a steel wire rod similar to the seat frame 12, and the single steel wire rod is formed in a closed loop shape as shown in the drawing, and will be described later at an upper end portion which is a folded portion. The hooked portion 13a is provided with a fixed portion 13b at the lower end. For example, as shown in FIG. 2, the movable frame 13 is inserted into hollow pipes 12c, 12c which are aligned vertically with respect to the horizontal frame 12b and fixed by welding or the like. The horizontal frame 12b is vertically movable.

The seat back 10 according to the present embodiment is configured as described above, and the mounting method thereof will be described next. As shown in FIG. 3, the rear surface side of the seat back 10 is opposed to the vehicle body side mounting surface 14 which is slightly inclined and is pressed rearward as indicated by an arrow B. An upward hook 14a is formed at a predetermined position on the vehicle body side mounting surface 14. At this time, the movable frame 13 provided through the hollow pipe 12c to the horizontal frame 12b of the seat frame formed vertically and horizontally on the back side of the seat back has its hooked portion 13a from the hook 14a. Is also located above. Next, the movable frame is lowered by pulling it in the direction of arrow A, that is, downward, and as shown in FIG. 4, the hooked portion 13a at the upper end is lowered to hook with the upward hook 14a. In this state, the fixed portion 13b at the lower end of the movable frame is advanced downward, so at its lowered position, the fixed portion 13b is screwed to the vehicle body side mounting surface 14, and the fixing work of the seat back 10 is completed.

As described above, the seat back 10 according to the present embodiment, like the conventional seat back, raises the seat back itself from the position to be fixed in advance during the fixing work, and then lowers it. Since it is not necessary to fix it and fix it, and just press the back side against the mounting surface on the vehicle body side, it is possible to fix it without the difficult work of lifting or lowering heavy objects. Moreover, since it is not necessary to lift the seat back 10, the upper corner portion 10a of the seat back 10 does not come into contact with the overhang portion of the roof side inner garnish 14 as in the conventional case. Therefore, as shown in FIG. 5, it is not necessary to chamfer the upper corner portion 10a in an R shape, and the seat back 10 is fixed, and the upper corner portion 10a and the roof side inner garnish 14 are fixed between the upper corner portion 10a and the roof side inner garnish 14. It is possible to effectively avoid the situation of creating a gap, and to provide a preferable appearance in terms of design.
