PROBLEM TO BE SOLVED: To enable arrangement for comfortable sleeping by forming a side arm in such a manner as to be moved between the disposition position as an arm rest to the draw-in position for forming a seat to be wider. SOLUTION: A side arm 26 is movably arranged on a shell 30. That is, the side arm 26 is adapted to be moved forward with a seat part 20 when the seat part 20 is changed into a bed. At this time, the side arm 26 is folded to be substantially flush with the upper surface of the seat part 20. Further, it may be lowered below the seat part 20. Further, it may be drawn in at the same position without movement with the seat part 20. The alternative form is such that the effective width of the seat part 20 is enlarged by drawing in one or both of the side arms 26. Thus, the side arms 26 can be drawn in so as to optimize the effective width of the bed. |
