Abstract
The chair of the present disclosure includes a base, a seating surface positioned on the upper side of the base and seated by a user, a base and a seating surface are connected, a seating surface is maintained in a reference state, and a seating surface is inclined from the reference state in accordance with a force applied to the seating surface by the seating of the user in accordance with the reference state; an elastic support post installed on the upper side of the base and rotating about an axis in the vertical direction based on power; a plurality of support posts installed on the upper side of the rotating table and supporting the seating surface at the upper end portion when the seating surface is inclined; and a motor that generates power.
Claims6
A chair comprising:
- a base;
- a seating surface located above the base and upon which a user sits;
- an elastic post that connects the base and the seating surface, wherein the elastic post is configured to maintain the seating surface in a reference state and incline the seating surface from the reference state in response to a force applied to the seating surface when the user is seated on the seating surface;
- a power transmission mechanism;
- a disc;
- a first support post and a second support post that are installed on an upper side of the disc and that support the seating surface at an upper end portion of at least one of the first support post and the second support post in a case where the seating surface is inclined;
- a motor configured to generate power;
- a first sensor;
- and
- a second sensor, wherein:
- the power transmission mechanism is configured to transmit the power to the disc,
- the disc is installed on an upper side of the base and is configured to rotate about an axis in an up-down direction based on the power received from the power transmission mechanism,
- the first support post contacts a lower side of the seating surface,
- a length in the up-down direction of the second support post is shorter than a predetermined length of the first support post,
- the first sensor is:
- installed on the lower side of the seating surface;
- and
- configured to measure an inclination direction of the seating surface with respect to a horizontal plane and an inclination angle of the seating surface with respect to the horizontal plane in a case where the user is seated, and
- the second sensor is:
- installed on an upper side of the seating surface;
- and
- configured to measure transition of a position of center of gravity of a subject that rides on the seating surface in a case where the user is seated.
