Abstract
A seal for a gap between two components which are displaceable relative to each other through limited distances in three spatial directions, the seal being formed by at least two partially overlapping corrugated, bellows-like seal elements which are arranged one after the other in the longitudinal direction of the gap. Each seal element is connected to one of the components at a fixed point of attachment and is slidably and guidably connected to both components. Adjacent seal elements can also be slidably and guidably connected to one another. The seal provides sealing action for comparatively large relative movements of the two components and, thus for greatly varying widths and shapes of the gap.
