Abstract
An airbag module for a motor vehicle includes a gas sack that can be inflated with gas to protect an occupant, a gas generator for generating the gas provided for inflating the gas sack, and an additional cooling device comprising an openable reservoir for storing a coolant. The reservoir is opened when the gas sack is inflated, so that the coolant for cooling the gas used to inflate the gas sack can come into contact with the gas. The cooling device comprises a movement generating device that opens the reservoir to release the coolant.
Claims13
A method for restraining an occupant of a motor vehicle with an airbag module, comprising the steps of:
- inflating a gas sack of the airbag module to protect the occupant, and
- releasing a coolant into an interior space of the gas sack with a cooling device of the airbag module to reduce the temperature prevailing in the interior space of the gas sack,
- wherein the time of the release of the coolant is calculated by an electronic control unit as a function of at least one parameter from a sensor unit assigned to the airbag module.
The method as claimed in 1, wherein the at least one parameter is sensed multiple times.
