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 lumber area of a person in human body supporting means, and an output signal of the sensor is transmitted to state analyzing means which analyzes a state of the person,wherein an 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.

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.
