PROBLEM TO BE SOLVED: To provide a seat belt and a sensor unit capable of obtaining a seat belt shape accurately as compared with a case of obtaining the seat belt shape from an observation image, and an occupant protection device capable of performing proper protection according to a state of an occupant by using the seat belt or the sensor unit.SOLUTION: An occupant protection device comprises: at least one sensor for detecting a physical quantity applied to an installation position, which is installed on a surface or an inside of a seat belt along a lengthwise direction of the seat belt; measurement means for measuring a curvature of the installation position of each sensor on the basis of the physical quantity detected by each sensor; shape acquisition means for acquiring a seat belt shape when it is worn based on the curvature of the installation position of each sensor measured when an occupant wears the seat belt; and control means for controlling occupant protection means to optimize an operation state of the occupant protection means on the basis of a seat belt wearing state of the occupant which is grasped from the acquired seat belt shape.SELECTED DRAWING: Figure 2

    【課題】観察映像からシートベルト形状を得る場合に比べて正確にシートベルト形状を得ることができるシートベルト及びセンサユニットと、前記シートベルト又は前記センサユニットを用いて乗員の状況に応じた適切な保護を行うことができる乗員保護装置とを提供する。【解決手段】シートベルトの長さ方向に沿って前記シートベルトの表面又は内部に設置され、設置位置に作用する物理量を検出する少なくとも1つのセンサと、センサの各々で検出された物理量に基づいてセンサの設置位置の各々の曲率を測定する測定手段と、乗員がシートベルトを装着した状態で測定されたセンサの設置位置の各々の曲率に基づいて装着時のシートベルト形状を取得する形状取得手段と、取得されたシートベルト形状から把握される乗員のシートベルト着用状態に基づいて乗員保護手段の作動状態が適正化されるよう乗員保護手段を制御する制御手段と、を備えた乗員保護装置とする。【選択図】図2
