【発明の名称】座位姿勢の変化に追従する机・椅子セット
Document Type and Number:
Japanese Patent JP2992597
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To cope even with long hour continuous work by sensing posture changing pressure of a seating person to a seat back and both armrests by pressure elements, and making a desk and a chair follow up to a specific maximum inclining-sideways turning angle. SOLUTION: A seat back part 14 and both left and right armrests 15 are arranged in a chair part 10, and plural pressure sensitive elements 16 are embedded in both. A desk and a chair integrally incline in a range of an elevation angle of 45 degrees at its maximum with the virtual rotational center 8 as the center. A sideways turning guiding flat pipe 26 also forms a circular rail with a virtual gravity center position being the virtual rotational center 8 as the center, and exists in a position to support an elevation angle guiding pipe 7 from outside. Sideways turning is made left and right by 30 degrees with the virtual rotational center 8 as the center. Since pressure is applied to the seat back part 14 and both armrests 15 of the chair part 10 and pressure is applied to the pressure sensitive elements 16, it can cope with a postural change. Since the desk and the chair follow a free postural change of a seating person while keeping a work related position normal, they can cope even with long hour continuous work.
