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.
