An energy absorber includes a base sheet and a plurality of recovering crush lobes extending from the base sheet. The crush lobes protect an adjacent object by cushioning the blow following repeated impacts in both vehicular and non-vehicular (e.g. helmets) environments. Each crush lobe includes a side wall that is oriented to buckle or bend and then spring back after absorbing energy when impacted. At least one of the base sheet and an end wall of at least one crush lobe optionally includes a number (X) of integrally-formed protruding countermeasures where 0<=X<1000 of lower standing strength than the crush lobes. Methods related to the above are also described.

The present invention provides a flexible member having excellent load resistance and flexibility while achieving a reduction in size. This flexible member is provided with: a main body part which includes multiple wave washers that are stacked in an axial direction and are joined to one another by multiple joint parts, and which is capable of bending relative to the axial direction by elastic deformation of the wave washers; and easily deformable parts formed between the joint parts that are adjacent to one another in the circumferential direction in each wave washer. 1. A flexible member comprising:a main body part that has a plurality of wave washers stacked in an axial direction and joined to each other by a plurality of joint parts, and the main body part is able to be bent with respect to the axial direction due to elastic deformation of the wave washers; andeasily deformable parts that are formed between the joint parts adjacent to each other in a circumferential direction in each of the wave washers, and the easily deformable parts are more readily deformable than other portions in the wave washers.2. The flexible member according to claim 1 ,wherein the easily deformable parts include: portions of the wave washer having a relatively small dimension in a radial direction of the wave washer.3. The flexible member according to claim 2 ,wherein the easily deformable parts are divided by recessed parts formed in the radial direction in an inner circumference of the wave washer.4. The flexible member according to claim 1 ,wherein the easily deformable parts include: portions of the wave washer having a relatively small plate thickness.5. The flexible member according to claim 1 ,wherein each of the plurality of joint parts includes: welded parts in linear shape, being extended from an inner circumferential side toward an outer circumferential side of the wave washer.6. The flexible member according to claim 5 ,wherein each of the joint parts includes a pair of ...

Systems and methods for limiting transmission of vibrations and forces causing vibrations from one element to another are provided. A vibration isolator may include a compressible inner member and an outer member compressible with the inner member. The outer member may be positioned at least partially around the inner member to provide lateral support to the inner member. The outer member may maintain a consistent diameter and compression force when in a compressed state. The outer member may include a tube with a zero or near-zero Poisson's ratio.
