DESCRIPTION OF SPECIFIC EXAMPLES Hereinafter, the seat back used for the rear seat of the automobile of the present invention will be described with reference to the specified and illustrated specific examples. FIGS. Partially showing a specific example 10 of a seat back used for a rear seat of an automobile of the present invention, which is applied to a seat.
The left and right brackets 15 and 16 have bearing holes 17 and 19,
Arcuate guide groove 18 centered on the bearing holes 17 and 19,
20 and is screwed to the center of the seat back frame (not shown) at a predetermined interval in the left-right direction, and the armrest 14 preliminarily supports the support pin 27 and the headed guide pin 28. The support pin 27 is fitted into the bearing holes 17 and 19, and the guide pin 28 is fitted into the arcuate guide grooves 18 and 20, respectively, and is supported by the left and right brackets 15 and 16, and is forwarded to the storage position. Further, one of the left and right brackets 15, 16 forms an enlarged opening 21 in the middle of the arc-shaped guide groove 18, and the head 29 of the guide pin 28 of the enlarged opening 21 is formed. The guide pin 28 can be fitted into the arc-shaped guide groove 18 through the enlarged opening 21.

The armrest 14 has its support pins 27 and guide pins 28 pre-assembled between the side brackets 25 and 26 of the frame 22, and then the cushion 23 is assembled to the frame 22 and the outer skin 24 is covered. It is assembled into a retrofit structure where it is finished.

Further, in the seat back 10,
11 is a seat back cushion, 12 is an outer skin, and 13 is a center pocket.

Next, the assembling of the armrest will be described. First, the seat back 10 is finished except for the armrests 14, and the armrests 14 are also finished by themselves. As such, they are finished separately so that, as shown in FIG. 3, the armrest 14 is then held by its support pin 27 and head 29 in the bearing hole 18 of its left bracket 15.
And the corresponding armrest 14 is moved to the left bracket 15 so as to fit the support pin 27 into the bearing hole 17, and at the same time, the head 29 is passed through the enlargement opening 21 to guide the pin. 28
Is fitted into the enlarged opening 21. Then, the armrest 14 is moved slightly toward the right bracket 16 to fit the support pin 27 into the bearing hole 19, and at the same time,
The guide pin 28 is fitted into the arcuate guide groove 20.

As described above, since the enlarged opening 21 is formed in the middle of the arc-shaped guide groove 18, the bearing hole 17, the enlarged opening 21, the support pin 27 and the guide pin 28 are visually recognizable.
The support pin 27 is fitted in the bearing hole 17 and the guide pin 28 is fitted in the arcuate guide groove 18 while checking the positional relationship of the armrest 14 and the armrest 14 is easily retrofitted to the seat back frame. It That is, the armrest 14 corresponds to the seat back 1
It can be retrofitted to zero with a simple operation. The guide pin 28 is prevented from slipping out of the arcuate guide groove 18 by the head 29 in the retracted position shown in FIG. 4 and the forward position shown in FIG. 5, and as a result, the armrest 14 is The left and right brackets 15 and 16 are prevented from coming off and supported by the seat back frame. That is, the armrest 14 is supported by the seat back 10 while being prevented from coming off in the storage position and the forward tilted position.

As will be apparent from the specific embodiments of the present invention described above with reference to the drawings, those of ordinary skill in the art to which the present invention pertains have the subject matter of the present invention. Is the nature of the invention (na
), and are readily embodied in other aspects that are objectively perceived as inherent in them. Of course, the content of the present invention corresponds to the subject of the invention (be commensu).
