The present invention is directed to an anchor for anchoring to an elevated worksite. The anchor includes a shock absorbing portion configured to progressively distort under sudden loading, the shock absorbing portion having one or more serpentine shaped members each defining one or more serpentine shaped curves visible from a front view of the shock absorbing portion, the shock absorbing portion having a curved profile defining one or more curves visible from a side view of the shock absorbing portion. The curved profile is configured to progressively distort under sudden loading so as to provide a first level of shock absorption, and the serpentine shaped curves are configured to progressively distort under sudden loading to provide a second level of shock absorption.

An axially damping elastomer bearing suitable for a motor vehicle, with a crucible-formed receptacle (13) for surrounding receiving an elastomeric support spring (15). The crucible-formed receptacle (13) is manufactured through casting and can be demolded in a demolding direction (39) and has a peripheral wall (19) with at least one drainage opening (33), wherein the at least one drainage opening (33) has a clearance (43, 45, 65) extending in the demolding direction (39).

An elastic structure includes an elastic member. The elastic member includes a substantially T-shaped metal sheet that is bent to form an elastic plate presenting a successive S-shaped profile. The elastic plate has a first end formed with a planar resting portion and a second end integrally formed with a substantially U-shaped head. The U-shaped head has two symmetrically arranged limit side plates resting on two sides of the elastic plate. Each of the two limit side plates of the U-shaped head has a length at least extending to a middle position of the elastic plate.
