Abstract

Disclosed is a biosensor arrangement structure, including: a plurality of biosensors that is disposed in a seat for supporting an occupant and that measures a health condition of the occupant. The seat includes: a seat body for holding the occupant; and an auxiliary supporter for supporting a body part of the occupant except for a torso and thighs. At least one of the plurality of biosensors is disposed at the auxiliary supporter.

First claim

The invention claimed is:

1. A biosensor arrangement structure, comprising:

wherein the seat includes: a seat body for holding the occupant; and an auxiliary supporter for supporting a body part of the occupant except for a torso and thighs,
wherein at least a first sensor of the plurality of biosensors is disposed at the auxiliary supporter,
wherein at least a second sensor of the plurality of biosensors is disposed at the seat body, and
wherein the first sensor of the plurality of biosensors is covered with a cover when the measurement is not performed.

2. The biosensor arrangement structure according to claim 1 ,
wherein the auxiliary supporter includes an arm rest for supporting an arm of the occupant, and
wherein a front upper end of the arm rest is a part where the first sensor of the plurality of biosensors is installed, and
wherein the part where the first sensor of the plurality of biosensors is installed includes a housing in the part, and the first sensor of the plurality of biosensors is housed in the housing when the measurement is not performed.

3. The biosensor arrangement structure according to claim 1 ,
wherein the auxiliary supporter includes a head rest for supporting a head of the occupant, and
wherein a front part of the head rest is a part where the first sensor of the plurality of biosensors is installed.

4. The biosensor arrangement structure according to claim 1 ,
wherein the auxiliary supporter includes a neck rest for supporting a neck of the occupant, and
wherein a front part of the neck rest is a part where the first sensor of the plurality of biosensors is installed.

5. The biosensor arrangement structure according to claim 1 ,
wherein the auxiliary supporter includes an ottoman for supporting legs of the occupant, and
wherein a right and/or left part of the ottoman is a part where the first sensor of the plurality of biosensors is installed, and
the ottoman is retracted and is not used while the occupant is driving a vehicle.

6. The biosensor arrangement structure according to claim 5 ,
wherein the auxiliary supporter includes a foot rest for supporting feet of the occupant,
wherein a right and/or left part of the foot rest is a part where the at least one of the plurality of biosensors is installed, and
wherein the foot rest and the ottoman are connected together to form a L shape to support the legs and the feet of the occupant.

7. The biosensor arrangement structure according to claim 1 ,
wherein the seat is installed in a vehicle with a driving controller for switching between autonomous driving and manual driving, and the seat is transformable into different forms between in the autonomous driving and in the manual driving, and
wherein the plurality of biosensors measure the health condition in the manual driving, and in response to deterioration of the health condition being detected, the driving controller switches a driving mode to the autonomous driving.

8. The biosensor arrangement structure according to claim 1 ,
wherein the second sensor of the plurality of biosensors is arranged at the seat body in a position that does not interfere with an air pathway for air conditioning.

9. A biosensor arrangement structure, comprising:
a plurality of biosensors that is disposed in a seat for supporting an occupant and that measures a health condition of the occupant,
wherein the seat includes: a seat body for holding the occupant; and an auxiliary supporter for supporting a body part of the occupant except for a torso and thighs,
wherein at least a first sensor of the plurality of biosensors is disposed at the auxiliary supporter,
wherein at least a second sensor of the plurality of biosensors is disposed at the seat body,
wherein the plurality of biosensors includes a photoelectric pulse wave sensor that uses light to measure a pulse wave of the occupant,
wherein the photoelectric pulse wave sensor is disposed under a covering material, and measures the pulse wave through a hole in the covering material,
wherein the photoelectric pulse wave sensor includes a light emitting part and a light receiving part, and
wherein only the light emitting part and the light receiving part are exposed on the covering material forming a surface of the seat body or the auxiliary supporter, and a part other than the light emitting part and the light receiving part of the photoelectric pulse wave sensor is covered with the covering material.

10. The biosensor arrangement structure according to claim 9 ,
wherein the auxiliary supporter includes an arm rest for supporting an arm of the occupant, and
wherein a front upper end of the arm rest is a part where the first sensor of the plurality of biosensors is installed, and
wherein the part where the first sensor of the plurality of biosensors is installed includes a housing in the part, and the first sensor of the plurality of biosensors is housed in the housing when the measurement is not performed.

11. The biosensor arrangement structure according to claim 9 ,
wherein the auxiliary supporter includes a head rest for supporting a head of the occupant, and
wherein a front part of the head rest is a part where the first sensor of the plurality of biosensors is installed.

12. The biosensor arrangement structure according to claim 9 ,
wherein the pulse wave sensor is a piezoelectric pulse wave sensor that measures a pressure wave on a body surface of the occupant to measure the pulse wave of the occupant.

13. The biosensor arrangement structure according to claim 9 ,
wherein the pulse wave sensor is an electromagnetic pulse wave sensor that uses an electromagnetic wave to measure a pulse wave of the occupant.

14. The biosensor arrangement structure according to claim 9 , wherein the seat is installed in a vehicle with a driving controller for switching between autonomous driving and manual driving, and the seat is transformable into different forms between in the autonomous driving and in the manual driving, and
wherein the plurality of biosensors measure the health condition in the manual driving, and in response to deterioration of the health condition being detected, the driving controller switches a driving mode to the autonomous driving.

15. The biosensor arrangement structure according to claim 9 ,
wherein the second sensor of the plurality of biosensors is arranged at the seat body in a position that does not interfere with an air pathway for air conditioning.

16. A biosensor arrangement structure, comprising:
a plurality of biosensors that is disposed in a seat for supporting an occupant and that measures a health condition of the occupant,
wherein the seat includes: a seat body for holding the occupant; and an auxiliary supporter for supporting a body part of the occupant except for a torso and thighs,
wherein at least a first sensor of the plurality of biosensors is disposed at the auxiliary supporter,
