Abstract

Disclosed is a seat including: sensors which includes a first cushion sensor provided at a seat cushion in a position corresponding to buttocks of an occupant, a second cushion sensor provided at the seat cushion and located farther frontward than the first cushion sensor, a first back sensor provided at a seat back and located in a lower position thereof, and a second back sensor provided at the seat back and located above the first back sensor; and a controller connected to the sensors and thereby allowed to acquire pressure values from the respective sensors. The controller is configured to identify the motion of the occupant based on outputs of at least two sensors of the first cushion sensor, the second cushion sensor, the first back sensor, and the second back sensor.

First claim

1 . A seat comprising:
a seat body; sensors configured to acquire measurement values for use in identifying motion of an occupant seated on the seat body; and a controller connected to the sensors and thereby allowed to acquire the measurement values from the sensors, wherein the seat body comprises a seat cushion and a seat back, wherein the sensors comprise a first cushion sensor provided at the seat cushion in a position thereof corresponding to buttocks of the occupant, a second cushion sensor provided at the seat cushion and located farther frontward than the first cushion sensor, a first back sensor provided at the seat back and located in a lower position thereof, and a second back sensor provided at the seat back and located above the first back sensor, and wherein the controller is configured to:
identify the motion of the occupant based on outputs of at least two sensors of the first cushion sensor, the second cushion sensor, the first back sensor, and the second back sensor.
