Occupant protecting apparatus
First Claim
1. An occupant protecting apparatus comprising:
- infrared beam emitting means disposed on an upper portion of an occupant room of a vehicle at a position diagonally rearward of a position of a passenger seat for emitting a flat infrared beam, infrared beam detecting means disposed on a position offset from said infrared beam emitting means for detecting a position of a light spot generated in such a manner that said infrared beam impinges on an occupant on a seat and scatters, and control means for obtaining a size of said occupant or a three-dimensional shape of a sitting position from output of said infrared beam detecting means to control motion of an air bag protecting apparatus.

Abstract
An occupant protecting apparatus capable of safely controlling the operation method with a simple structure. The occupant protecting apparatus comprises infrared beam emitting device (11) disposed on an upper portion of an occupant room of a vehicle at a position diagonally rearward of a position of a passenger seat for emitting an infrared beam, an infrared beam detecting device (16) disposed on a position offset from the infrared beam emitting device for detecting a position of a light spot generated in such a manner that flat infrared beam impinges an occupant on a seat and scatters, and a control device for obtaining a size of the occupant or a three-dimensional shape of sitting position or the like from output of the infrared beam detecting device to control motion of a protecting apparatus such as an air bag (3).
