Title:
BIOLOGICAL INFORMATION DETECTION DEVICE AND SEATING ASSESSMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/215645
Kind Code:
A1
Abstract:
This biological information detection device is provided with: a bag-shaped first member which is filled with air and which has a first surface and a second surface facing one another; a bag-shaped second member which is filled with air and which has a third surface and a fourth surface facing one another, the third surface facing the second surface; a module provided with a first pusher that is located at the center of the first surface as seen from the direction of stacking of the first member and the second member, and a second pusher that is in contact with at least the center of the fourth surface; and a detector for detecting the difference between the gas pressure inside the first member and the gas pressure inside the second member. The distance between the first surface and a fifth surface, which is a surface of the first pusher and faces the first surface, decreases going from the peripheral edge toward the center. Vibrations can be transmitted between the first surface and the fifth surface.
