The invention relates to 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, and a closure element for closing the outflow opening. According to the invention it is provided that the closure element divides the reservoir into the two portions, and 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. Further, the invention relates to a method for producing an airbag module.

1. 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; anda 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. 2. The airbag module as claimed in claim 1, wherein the closure element is movable in the reservoir in order to allow the coolant to escape out of the reservoir and is also arranged in the reservoir after said movement. 3. The airbag module as claimed in claim 1, wherein the reservoir comprises a wall extending longitudinally along the movement direction, that circulates across the movement direction, wherein said wall is particularly formed hollow-cylindrical at least in sections. 4. The airbag module as claimed in claim 3, wherein the outflow opening is formed at the wall, so that the coolant is discharged out of the reservoir through said outflow opening across the movement direction. 5. The airbag module as claimed in claim 1, wherein the closure element is formed deformable, particularly elastically deformable. 6. The airbag module as claimed in claim 1, wherein the movement generating device is formed by a gas generator that is particularly crimped with a free end of the first portion of the reservoir. 7. The airbag module as claimed in claim 1, wherein the reservoir is formed tubular. 8. The airbag module as claimed in claim 1, wherein the reservoir is arranged at a retaining element of the airbag module, that serves for fastening the gas sack in the airbag module, wherein the reservoir is particularly integrated into the retaining element. 9. The airbag module as claimed in claim 8, wherein the reservoir is arranged at a flange of the retaining element of the airbag module, particularly integrated into the flange. 10. The airbag module as claimed in claim 1, wherein the reservoir is angled in a way that the reservoir protrudes, with a portion that comprises the movement generating device in particular, out of the gas sack, wherein said portion extends in particular perpendicular to the flange. 11. 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; anda 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, andwherein a further closure element is provided, that can be moved out of an initial position, in which the further closure element is arranged such that the coolant is enclosed between the two closure means, into in a final position, wherein the further closure means, upon its movement into its final position, takes along the coolant and the one closure means in order to set free the coolant. 12. The airbag module as claimed in claim 11, wherein a movement generating device is configured and provided to act on the coolant with a pressure via the further closure means, so that the further closure means presses the coolant out of the reservoir and thereby presses the one closure element out of its initial position into its final position. 13. A method for producing an airbag module, comprising the steps of: providing a tube extending longitudinally along an extension direction, that is divided into a first and a second portion along the extension direction;forming at least one outflow opening merely at the second portion; andinserting a closure element into the tube, so that the closure element divides the tube into the first and the second portion,wherein a further closure means is inserted into the first portion, particularly through an opening of the first portion, which is delimited by a free end of the first portion, so that the two closure means enclose a coolant, andwherein, as the closure element, a deformable, particularly elastically deformable element is inserted into the tube, that seals the first portion with respect to the second portion, so that coolant residing in the first portion cannot escape through the at least one outflow opening formed at the second portion. 14. The method as claimed in claim 13, wherein a free end of the second portion that faces the free end of the first portion along the extension direction, is narrowed, in order to avoid that the closure element can be pressed out of the tube along the extension direction. 15. The method as claimed in claim 14, wherein a movement generating device is inserted into the first portion of the tube, particularly through said free end of the first portion, wherein particularly the movement generating device is fastened to said first portion after insertion into the first portion. 16. The method as claimed in claim 13, wherein the coolant is filled in the first portion, particularly through the opening of the first portion.
