Braking device for use in protection system for curbing distance of one element with regard to another element, has element separated from another element to exert traction longitudinally on support of part in direction of end of other part

摘要

The device (10) has a part (11) comprising a support (13) fixed on an element. A roller (23) is mounted on the support so as to define a passage zone (50) in the part. A hollow cylindrical portion (33) is arranged adjacent to the deformation unit on a side of the element in a mounted position. The element is separated from another element by a distance so as to exert traction longitudinally on the support of the part in a direction of an end (31) of another part (12) to cause crushing of a part of the cylindrical portion in the passage zone by the roller. An independent claim is also included for a protection system.
