The back rest 61 is supported so as to revolve in a vertical direction on a base by rotatably coupling an operation plate 66 fixed to the back face side to the base 1, the foot rest 64 is connected to the base 1 via a hinge member 69. The thigh rest 62 is connected to the base 1 via connecting rod 8, one end side of the thigh rest 62 is raised up by the connecting rod 8 and the joint of the thigh rest 62 and the lower thigh rest 63 is bent upward in a convex shape when the back rest 61 is revolved upward. The thigh rest 62 is horizontally supported by the base 1 and the foot rest 64 folded to the back side of the lower thigh rest 63 at a lower position of the thigh rest 62 in a condition where the back rest 61 is raised to a position. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
