Abstract: An assembly kit for an aircraft seat, comprising at least one mounting unit, at least one backrest which is fixedly coupled with the mounting unit in a state when assembled and ready for flight, and at least one connection module, via which the backrest is in particular oriented rigidly in a position relative to the mounting unit in the assembled and ready-for-flight state, and the connection module comprises at least one adjusting element, by means of which the backrest is orientable respectively in at least two different backrest adjustment angles relative to the mounting unit without requiring new approval, and/or comprises at least two connection elements, by means of which the backrest can be fixedly mounted respectively in at least two different backrest adjustment angles relative to the mounting unit, the at least two connection elements being mountable without requiring new approval.

Abstract: An airplane seat device having at least one backrest, at least one seat component coupled to the backrest and a backrest impact safety device which, by partially decoupling the backrest from the seat component, is provided to at least partly reduce impact forces on the backrest at least in the event of crash. The backrest impact safety device is provided to decouple the backrest from the seat component before the impact forces takes effect.
