Abstract

A passenger protection apparatus has plural kinds of passenger protectors, e.g., air bags and seat belt retractors, which are actuated when a scale of collision of a vehicle is above an actuation level. It has a memory for memorizing actuation levels which are set in advance for each kind of the passenger protectors. The apparatus has a corrector for correcting the actuation level, which is kept in the memory, of non-actuated kind of passenger protector to a lower level when at least one kind, out of the plural kinds, of passenger protectors is actuated. In case the passenger protection apparatus is made up of a gas-actuated air bag which is actuated by a plularity of gas generators, it has also a memory for memorizing actuation levels which are set in advance for each of the gas generators. An actuation level corrector corrects the actuation level, which is kept in the memory, of a non-actuated gas generator to a lower level when at least one of the plurality of gas generators is actuated.

Claims

1. A passenger protection apparatus having plural kinds of passenger protection means which are actuated when a scale of collision of a vehicle is above an actuation level,

said passenger protection apparatus comprising memory means for memorizing actuation levels which are set in advance for each kind of said passenger protection means,

wherein actuation level correction means is provided for correcting the actuation level, which is kept in memory in said memory means, of a non-actuated kind of passenger protection means to a lower level when at least one kind, out of said plural kinds, of passenger protection means is actuated.

2. A passenger protection apparatus according to claim 1, wherein said passenger protection means comprise an air bag apparatus and a seat belt retraction apparatus.

3. A passenger protection apparatus having passenger protection means which is actuated by gas pressure when a scale of collision of a vehicle is above an actuation level,

said passenger protection apparatus comprising a plurality of gas generating devices for actuating said passenger protection means, and memory means for memorizing actuation levels which are set in advance for each of said gas generating devices,

wherein actuation level correction means is provided for correcting the actuation level, which is kept in memory in said memory means, of a non-actuated gas generating device to a lower level when at least one of said plurality of gas generating devices is actuated.
