PURPOSE:To prevent a seat from being moved fowards or backwards at the time of a rotating operation, by a slide adjustor with a stopper interlocked with a rotation-locking mechanism. CONSTITUTION:A turning mechanism (a) for the lower surface of the seat is comprised of a seat-fitting base 40 and circular disk form rotating support members 41, 42 fixed to a ground base 26, and is locked by engaging a stopping plate 44 into stopping grooves 43, 43' of the fitting base 40 and the support member 41. The slide adjustor (b) is comprised of a fixed rail 21 and a movable rail 22 (which are fixed respectively to the base 25 and the base 26), a locking mechanism 23 and an unlocking mechanism 24. A rotatable piece 23b of the locking mechanism 23 is provided with a stopper 1, which is connected to a rotary shaft 31 of the turning mechanism (a). Simultaneously when the turning mechanism (a) is unlocked, the stopper 1 functions to disenable the operation of the unlocking mechanism 24 for the slide adjustor (b). |
