Abstract

A respiratory detection device detects a behavior of breathing of an occupant on a seat of a vehicle. A seatbelt is equipped by the occupant to retain the occupant at the seat. A detection belt is mounted to the vehicle or the seat at one-end side. The detection belt is further connected to the seatbelt at the other-end side. The detection belt is equipped by the occupant together with the seatbelt when the occupant equips the seatbelt. A sensor is connected to the detection belt to detect the behavior of breathing. The detection belt retains the sensor at a position of an abdomen of the occupant when the occupant equips the seatbelt.

First claim

What is claimed is:

1. A respiratory detection device configured to detect a behavior of breathing of an occupant on a seat of a vehicle, the respiratory detection device comprising:
a seatbelt configured to be equipped by the occupant to retain the occupant at the seat;
a detection belt mounted to the vehicle or the seat at one-end side, the detection belt connected to the seatbelt at an other-end side, the detection belt configured to be equipped by the occupant together with the seatbelt when the occupant equips the seatbelt; and
a sensor connected to the detection belt and configured to detect the behavior of breathing, wherein
the detection belt is configured to retain the sensor at a position of an abdomen of the occupant when the occupant equips the seatbelt.

2. The respiratory detection device according to claim 1 , wherein
the seatbelt is a three-point seatbelt including a shoulder belt and a waist belt,
the shoulder belt is configured to press a chest of the occupant,
the waist belt is configured to press a waist of the occupant, and
the detection belt is connected to the shoulder belt at the other-end side.

3. The respiratory detection device according to claim 1 , wherein
the detection belt is at least partially in contact with the abdomen of the occupant when the occupant equips the seatbelt,
the sensor is located at a portion of the detection belt, and
the portion of the detection belt makes contact with the abdomen of the occupant when the occupant equips the seatbelt.

4. The respiratory detection device according to claim 2 , further comprising:
a wire affixed to the detection belt or the waist belt at one end, the wire installed to extend back and forth between the detection belt and the waist belt for a plurality of times; and
a tensioning unit equipped to an other end of the wire, the tensioning unit configured to apply a tensional force onto the wire to stretch the wire between the detection belt and the waist belt, wherein
the sensor is equipped to the tensioning unit and is configured to detect a drawing amount of the wire or a change in the tensional force of the wire caused by a motion of the abdomen of the occupant.
