FIG. 5 shows a state in which the child seat CRS described later is operated by operating the child seat / armrest 3. The child seat CRS constituted by the cushion part 6 and the two auxiliary cushion parts 7, 7 has the above-described structure. Is wider than a width W6 of an armrest A described later.

Next, the operation of operating the child seat / armrest 3 to configure the armrest, the central seat SC of the rear seat RS, and the child seat 3 will be described. 1 and 3, the operation for configuring the armrest A is performed as follows. First, the cushion portion 6 is placed on the seat cushion 1 by rotating the cushion portion 6 with respect to the seat cushion 1 to fall down, and the cushion portion 6 occupies the second position. Shoulder belts 44a,
The chest pad 4 is placed on the front of the cushion 6 with the chest pad 41 facing down while the 44b is being fed out. While the chest pad 4 is placed on the front part of the cushion part 6 in this manner, the auxiliary cushion parts 7, 7 are folded inward toward the center of the upper surface of the cushion part 6 with the shoulder belts 44a, 44b sandwiched under the chest pad 4. Is configured. The positioning of the chest pad 4 on the upper front portion of the cushion portion 6 may be performed by attaching a magic fastener (trade name) to a predetermined portion of the cushion portion 6 or the chest pad 4.

In FIG. 4, the operation for forming the central seat SC of the rear seat RS is performed as follows. First, the cushion portion 6 with respect to the seat cushion 1
Is turned upright, so that the cushion portion 6
By pressing the back portion 5 against the urging force of the compression coil spring 86 through the chest pad 4 and the auxiliary cushion pads 7, 7, the back portion 5 is moved in the storage space S in the backward direction by the parallel link mechanism 80. Following the movement, the cushion portion 6 occupies the first position. By operating the stopper (not shown) to hold the cushion portion 6 stored in the storage space S of the seat back 2 in the same state as shown in the drawing, the central seat SC of the rear seat RS is configured.

In FIG. 2, FIG. 3, and FIG. 7, the operation for constructing the child seat CRS is performed as follows. First, the auxiliary cushion portions 7 and 7 are rotated and deployed with respect to the cushion portion 6 from the armrest A state in FIG. 3, and the chest pad 4 is opened as shown in FIG. The child seat CRS is constructed by connecting the tongue 91 and the buckle 92 of the 90 and then closing the chest pad 4 to the state shown in FIG. In addition, when the infant is sitting on the seat, an auxiliary cushion body 78 (see FIG.
(Indicated by phantom lines) to fill the groove 65 to the extent that it does not interfere with the seating,
Safety measures are taken to avoid touching.

In the above embodiment, the rear end of the cushion 6 is attached to the lower end of the seat back 2 by the pivot 26.
The seat cushion 1 is rotatably provided to the seat cushion 1 via a pivot, but the present invention is not limited to this. You may.

In the above embodiment, the auxiliary cushion 7
Is provided on the upper surface of the cushion portion 6 of the child seat, but is not limited to this. As shown in FIG. 8, an auxiliary cushion portion 7a is provided on the lower surface of the seat cushion portion 6a.
