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.

Seal means for sealing a gap between two spaced components which are relatively displaceable in three directions in space, said seal means comprising at least two seal elements extending longitudinally in the gap between two spaced components, said seal elements partially overlapping one another in the longitudinal direction, said seal elements each being of corrugated, bellows-like shape with bends extending in the longitudinal direction, means fixedly connecting each of the seal elements at a respective point of attachment to one of said components and means guidably connecting each seal element to both said components for slidable movement at least in the longitudinal direction.
