  • Patent number: 9090349
    Abstract: The invention relates to a bearing application for staircases in an aircraft with at least two decks. According to the invention at least two bearings, each with at least partially different possibilities of movement about and along or parallel to the x-axis, y-axis and z-axis of a system of coordinates, are arranged on each staircase at the lower and upper staircase end (rotatory and/or translational movements). Due to the presence of at least four bearings on each staircase, the relative movements between decks can be compensated for. Consequently the static design of the staircases can be limited to the intrinsic weight and operation-related loads by the mass of the users, thereby providing weight savings.
