Document Type and Number:

Japanese Patent JP3770546

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To restrain dislocation of the body and pressure to the body at back lifting time by bringing the rotational center of the bottom near to a large rotary piece.
SOLUTION: This back lifting mechanism has a back lifting link 6 for rotatably installing the base end side vicinity on an intermediate floor 4, and allowing the tip side to movably abut to a back frame member 3 via a rolling member 5, a back frame support link 7 for fastening an upper end part by a shaft to the base end side of the back frame member 3, a back lifting auxiliary link 8 for rotatably installing one end side on the lower end side of this back frame support link 7, and a parallel link 9 arranged in parallel in the length equal to this back lifting auxiliary link 8, and is constituted by rotatably installing the other end side of these back lifting auxiliary link 8 and parallel link 9 in an installing part 10 of the intermediate floor 4. The base end side of the back lifting link 6 and a starting arm 11 installed on the other end side of the back lifting auxiliary link 8 are connected by an interlocking rod 12, and a linearly moving driving means 13 is connected to this interlocking rod 12. The back frame member 3 is slantingly displaced by starting this linearly moving driving means 13.
