A double-walled pipe connection for an aircraft fuel line includes a first outer pipe surrounding a first inner pipe, a second outer pipe surrounding a second inner pipe, a pipe coupling joining the inner pipes together, a securing fixture on the first inner pipe, a sleeve-shaped outer pipe bushing
A double-walled pipe connection for an aircraft fuel line includes a first outer pipe surrounding a first inner pipe, a second outer pipe surrounding a second inner pipe, a pipe coupling joining the inner pipes together, a securing fixture on the first inner pipe, a sleeve-shaped outer pipe bushing bolted to the securing fixture by bolts oriented parallel to a radial direction, and an outer pipe sleeve that is axially slidable over the second outer pipe and onto the outer pipe bushing. The first outer pipe is plugged into the outer pipe bushing, which is plugged into the outer pipe sleeve, which seals onto the second outer pipe. The inner pipe coupling is covered or exposed by axially moving the outer pipe sleeve, while the outer pipe bushing remains bolted to the first inner pipe, and mechanically secured and electrically grounded to a metal structure.

The device of claim 12, wherein the baseplate is configured to be a support for the gas generator. 14. The device of claim 12, wherein the baseplate is configured to be a support for an annular retaining element of the airbag. 15. The device of claim 1, wherein the structural element includes a predetermined breaking point which can be broken open by the inflating airbag. 16. The device of claim 1, wherein the predetermined breakpoint is located essentially opposite the gas generator. 17. The device of claim 1, wherein the structural element is a unitarily formed element. 18. The device of claim 1, wherein the airbag module is connected to and supported by the structural element. 19. A seat for a motor vehicle, comprising: a back wall formed by a structural element; an airbag module integrated into the seat and including a modular unit having an inflatable side airbag and a gas generator; wherein the modular unit is configured to be handled as a cohesive unit; wherein the structural element serves as a cover for the modular unit; and wherein the structural element is integral with the back wall and has a predetermined breaking point therein. 20. The seat of claim 19, wherein the cover extends substantially perpendicular with respects the backrest of the vehicle seat. 21. The seat of claim 19, wherein the structural element forms part of a side wall of the vehicle seat. 22. The seat of claim 19, wherein the modular unit is configured to be prefitted to the structural element prior to being attached to the vehicle seat. 23. The seat of claim 19, wherein the structural element comprises a first section forming the back wall of the vehicle seat and a second section forming the cover wherein the first and second sections extend approximately perpendicular with respect to each other. 24. The device of claim 19, wherein the predetermined breakpoint is located essentially opposite the gas generator. 25. The device of claim 19, wherein the structural element is a unitarily formed element. 26. The device of claim 19, wherein the airbag module is connected to and supported by the structural element.
