Abstract
An apparatus (10) comprises a vehicle occupant protection device (14), and an actuator (10) for the vehicle occupant protection device (14). The actuator (10) includes a gas generating material (18) or both a gas generating material (18) and an autoignition material (66). The gas generating material (18), the autoignition material (66), or both the gas generating material (18) and the autoignition material (66) comprise a plasticized cyclodextrin nitrate ester. The plasticized cyclodextrin nitrate ester has an autoignition temperature in the range of about 150° C. to about 180° C. and is resistant to thermal decomposition at a temperature less than 150° C.
Claims37
An apparatus comprising;
- a vehicle occupant protection device;
- and
- an actuator for actuating said vehicle occupant protection device, said actuator including a gas generating material or both a gas generating material and an autoignition material, said gas generating material, said autoignition material, or both said gas generating material and said autoignition material comprising a plasticized cyclodextrin nitrate ester that has an autoignition temperature in the range of about 150° C. to about 180° C. and is resistant to thermal decomposition at a temperature less than 150° C.
An apparatus comprising;
- a vehicle occupant protection device;
- and
- an inflator for inflating said vehicle occupant protection device, said inflator including a gas generating material for producing gas for inflating said vehicle occupant protection device, said gas generating material comprising a plasticized cyclodextrin nitrate ester that has an autoignition temperature in the range of about 150° C. to about 180° C. and is resistant to thermal decomposition at a temperature less than 150° C. and an oxidizer.
An apparatus comprising;
- an inflatable vehicle occupant protection device;
- an inflator housing;
- a gas generating material within said inflator housing, said gas generating material, when ignited, generating gas for inflating the vehicle occupant protection device;
- and
- an autoignition material for igniting said gas generating material, said autoignition material comprising a plasticized cyclodextrin nitrate ester that has an autoignition temperature in the range of about 150° C. to about 180° C. and is resistant to thermal decomposition at a temperature less than 150° C.
An apparatus comprising:
- an inflatable vehicle occupant protection device;
- an inflator housing;
- a gas generating material within said inflator housing, said gas generating material, when ignited, generating gas for inflating the vehicle occupant protection device;
- and
- an autoignition material for igniting said gas generating material, said autoignition material comprising a plasticized cyclodextrin nitrate ester that has an autoignition temperature in the range of about 150° C. to about 180° C. and is resistant to thermal decomposition at a temperature less than 150° C., wherein the ratio of cyclodextrin nitrate ester to plasticizer is from about 9:1 to about 1:1.5.
