BIOLOGICAL INFORMATION DETECTION DEVICE AND CHAIR INCLUDING BIOLOGICAL INFORMATION DETECTION DEVICE
A biological information detection device is installed in equipment including a body support portion, and detects biological information of a user of the equipment. The device includes: a detection unit including: a transmitter which transmits a radio wave toward a part of the body supported by the body support portion; and a receiver which receives a reflected wave obtained as the radio wave transmitted by the transmitter and then reflected on a part of the body; and a detection support portion which forms a part of the body support portion, and which supports a part of the body to which the transmitter transmits the radio wave. Hardness with respect to a part of the body at the detection support portion is softer than hardness with respect to a part of the body at the body support portion excluding the detection support portion.
1 . A biological information detection device which is installed in equipment comprising a body support portion which supports a body, and which detects biological information of a user of the equipment, the biological information detection device comprising:
a detection unit comprising: a transmitter which transmits a radio wave toward a part of the body supported by the body support portion; and a receiver which receives a reflected wave obtained as the radio wave transmitted by the transmitter and then reflected on a part of the body; and
a detection support portion which forms a part of the body support portion, and which supports a part of the body to which the transmitter transmits the radio wave,
wherein hardness with respect to a part of the body at the detection support portion is softer than hardness with respect to a part of the body at the body support portion excluding the detection support portion.
2 . The biological information detection device according to claim 1 ,
wherein the detection support portion comprises an elastic member.
3 . The biological information detection device according to claim 1 , further comprising:
a frame body comprising: a bottom portion on which the detection unit is disposed; and a side portion which is erected from the bottom portion to a surface on which the detection support portion supports a part of the body,
wherein the detection support portion is disposed across an inside of the side portion.
4 . A chair comprising:
the biological information detection device according to claim 1 ;
a support body that directly or indirectly supports the detection unit; and
a seat surface comprising the body support portion.
