Biological signal measuring device and biological state analyzing system
First Claim
1. A biological signal measuring device comprising:
- an air cushion provided with an airbag and a sensor which detects air pressure fluctuation of the airbag according to load fluctuation, wherein the air cushion is assembled between a skin member and a cushion supporting member arranged on a back face side of the skin member at a site supporting at least the vicinity of a lumbar area of a person, whereinan elastic member made of expanded resin beads which has a size covering the air cushion is disposed between the skin member and the air cushion and is configured by stacking a first elastic member made of expanded resin beads and a second elastic member made of expanded resin beads to each other, and each of the first elastic member made of expanded resin beads and the second elastic member made of expanded resin beads comprises an expanded bead body and a covering material covering an outer face of the expanded bead body.

Abstract
A configuration is adopted where elastic members made of expanded rein beads and having a size covering air cushions are disposed between a skin member and the air cushions of a human body supporting device. By arranging a plurality of elastic members made of expanded rein beads and in a stacking manner, preferably, arranging two elastic members made of expanded resin beads, spring constants of the elastic members obtained from load-deflection characteristics when they are pressed to a deflection amount of 1 mm by a pressing plate with a diameter of 30 mm being higher than that of the air cushion and being different from each other, a biological signal can be transmitted to the air cushions without damping the biological signal, though the elastic members made of expanded rein beads and are provided.
