摘要

The seal (1) includes U-shaped bellows (5) covering the transition floor (10). The bellows have a flexible frame (3) on the free open end, which has a buffer (4) of yielding elastic material. The buffer can divide the bellows into two parts. The bellows may have two arms (5a) connected by a web, and can be divided in the region of both arms.
