Seat angle change equipment

The smart chair guides user's posture and prevents excessive physical load

Overview

　It is known that if a person’s posture is maintained in a sitting position for an excessively long period of time, it can be harmful to his/her health. For example, it is known that there is a correlation between abovementioned period of time and the probability of suffering from diseases such as musculoskeletal disorder, heart failure, or lifestyle-related disease.

　In this invention, the chair seat is slightly inclined in order to guide the person to standing position naturally. Another key feature is the realization of a tilt method that does not interfere with the user's original task, such as desk work.

　In addition, various applications can be envisioned by linking with functions provided by smartdevices such as reminder function, etc.
