Divisible shell for a seat

A shell for a seat, particularly for a simulator, includes a seat surface, a backrest and side parts. The shell includes two or more shell parts connected releasably to each other. The shell parts are connectable to each other along a dividing plane. The dividing plane can run substantially parallel to or enclose a small angle with a plane which connects a front side of the seat surface to an upper side of the backrest, and the shell parts can extend substantially equally far from the dividing plane in a direction transversely thereof. A method for transporting a shell for a seat includes: providing two shell parts which can be connected releasably to each other to form the shell; placing the shell parts in each other; and placing the shell parts which are placed in each other in a packaging.
