Abstract

PURPOSE:To provide a chair whose shape can be easily changed and fixed by only one action to be comfortable for everyone. CONSTITUTION:The mechanical devices are controlled by making the hydraulic pressure cylinder mobile or fixed by opening or closing the push side and the pulling side of the cylinder. For the purpose, 'open' and 'close' operation is made with many shift valves 35, and this operation is done by hand at a time using the levers 1, 2, or 3 which have pumps inside. By only one action of a pump lever, it is possible to 'open' or 'close' the devices for; movement for the chair height control; forward/backward movement of the chair; flection movement of the back; movement to change the width between the thighs; up/down or forward/backward movement under the lap; movement to change the width between the arms; up/down movement of the seat; up/down movement of the headrest; and forward/backward movement of the headrest. And in addition, the number of selection of the mechanical devices can be freely decided.
