The cushion of the frame 17 The frame The bolt 18 is bolted to the device bracket 34 of the rear 18 and the upper bracket 31 is rotatably connected to the lower bracket 29 with the hinge pin at the free hinge 21 The seat cushion 11 is supported so as to be adjustable in angle. Then, the center armrest 16 is supported in a foldable manner between the left and right seat backs 12 and 13 and can swing between the forward-down position and the folding position.
[0009]
As such, in the rear seat 10, the center armrest 16 is easily foldably assembled between the left and right seat backs 12 and 13 by utilizing the reclining devices 19 and 20. The number of man-hours for the assembling work is reduced, and the brackets, bolts, nuts and the like used for assembling the center armrest 16 are omitted, and the cost is reduced.
[0010]
In the rear seat 10, the center armrest 16 is disposed so as to be foldable between the left and right seat backs 12, 13, but the center back is similarly arranged on the left and right seat backs. 12 and 13 may be arranged so as to be foldable. In this case, it is desirable that the center back can be used as the center armrest 16.
[0011]
