Patent ID: 8136836

Claim:
An airbag module for a motor vehicle, comprising: a gas sack, that can be inflated in order to protect a person by feeding gas into the gas sack; an openable reservoir for storing a coolant, wherein the reservoir comprises a first and a second portion, the second portion connected to the first portion; at least one outflow opening of the reservoir formed in the second portion, through which the coolant, for cooling the gas fed into the gas sack, can leave the reservoir; a closure element for preventing the coolant from escaping the reservoir, wherein the closure element divides the reservoir into the two portions, and in that the coolant is arranged in the first portion, wherein the closure element seals the first portion of the reservoir with respect to the second portion of the reservoir, and wherein the closure element can be moved along a movement direction out of an initial position in which the closure element divides the reservoir into the two portions into a final position in which the coolant can leave the reservoir from the first section via the second section through the at least one outflow opening; and a movement generating device that is configured and provided to act on the coolant with a pressure, so that the coolant presses the closure element out of the initial position into the final position.
