The basic configuration of the second sheet 13 is substantially the same as the first sheet 11.

First sheet 11 and second sheet 13
Is provided with a slide guide mechanism for expanding and storing the second sheet 13 with respect to the first sheet 11 as shown by a double-headed arrow A in FIG. The slide guide mechanism is provided on the side of the first and second seat cushions 14 and 18, preferably on both sides, and the first seat 11 and the second seat 1 are provided via the slide guide mechanism.
3 are linked.

As shown in FIG. 4, the slide guide mechanism includes a guide rail 22 formed by a part of the frame of the first seat 11, and a slide rail formed by a part of the frame of the second seat 13. As shown in FIG. 3, the slide rail 23 is slidably inserted into the guide rail 22. The guide rail 22 is formed so as to extend substantially horizontally forward on the side of the seat cushion 14 of the first seat.

The slide guide mechanism is provided with locking means for locking the slide guide mechanism and fixing the first sheet 11 and the second sheet 13 at predetermined positions. In this embodiment, a lock knob 24 is provided on the guide rail 22 side of the first seat 11. The lock knob 24 is fixed to an end of a shaft 26 attached to the guide rail 22 via a spring 25 as shown in FIG. The shaft 26 is movable in its axial direction. The shaft 26 engages with lock holes 27 (two in the front and rear in this example) provided in the slide rail 23. In this manner, the first seat 11 and the second seat 13 can be fixed at predetermined positions by operating the lock knob 24.
