A shock absorbing apparatus (suppressor) for a vibratory pile driver includes three suppressor sections, including a first section adapted and arranged to absorb a load up to a selected amount. A second suppressor section is adapted to absorb a load above the first shock-absorbing section, with a third suppressor system providing a transition between first and second suppressor action as load increases.

The disclosure is directed to a single layer including a plurality of unit cells. Each unit cell includes a first bowling pin structure interlocked with a second bowling pin structure arranged in an opposite orientation to the first bowling pin structure. The first bowling pin structure has a first sidewall, a first wide end, and an opposing first narrow or equal size end. Likewise, the second bowling pin structure has a second sidewall, a second wide end. Each of the bowling pin structures has a center axis along a longitudinal axis of the single layer structure. The first and second sidewalls are configured to have a 3D “S” shape along the longitudinal or vertical axis such that each of the first wide end and the second wide end has a convex shape and each of the first narrow or equal size end and the second narrow or equal size end has a concave shape.

The present invention relates to a thermoplastic spring, comprising a lower spring base portion (1) and an upper spring base portion (2), a female spring die (3) and a male spring die (4), wherein the female spring die (3) and the male spring die (4) are located between the lower spring base portion (1) and the upper spring base portion (2), wherein a pin is located on the male spring die (4) and a hole is located on the female spring die (3), wherein an installation process of the thermoplastic spring is performed by placing the placing the pin through the hole.

The shock absorber includes: a base portion fixed to the attachment target; a shock absorbing portion having flexibility and attached to the base portion so as to be reversibly switchable between a housed state in which the shock absorbing portion is retracted toward the base portion and a protruding state in which the shock absorbing portion protrudes from the base portion; and a drive unit driving the shock absorbing portion to reversibly switch between the housed state and the protruding state. The drive unit, when operating the shock absorbing portion, at least switches the shock absorbing portion from the housed state to the protruding state.

A shock absorber includes a first end fitting connected to a first telescoping member, a second end fitting connected to a second telescoping member, the first and second telescoping members being telescopically mounted relative to each other. An elastomeric spring/damper is disposed between the first telescoping member and the second telescoping member.

A shock isolation cushion has two basal components and at least one shock isolation tier. The two basal components are disposed at an interval. The at least one shock isolation tier is disposed between the two basal components and is sequentially stacked from one of the two basal components to the other one of the two basal components. Wherein each of the at least one shock isolation tier has multiple shock isolation units. Each of the multiple shock isolation units has a supporting section and at least two buffering sections. The at least two buffering sections respectively extend from two opposite ends of the supporting section. Each of the at least two buffering sections is curved to form an opening between the buffering section and the supporting section.

A damper unit for use in a vibration-reducing assembly for a steering wheel is disclosed. The damper unit includes a slider configured, upon horn activation, to slide on a guide shaft. A damper element made from an elastomeric material is arranged on a first part of the slider. A molded horn spring element is molded directly on a second part of the slider and is configured to exert a spring force on the slider. The damper unit provides a unitary structure providing both a vibration damping function and a horn spring function in one single assembly unit, reducing the number of components to assemble. A vibration-reducing damper assembly including one or more such damper units is also disclosed, as well as a method of making such a damper unit.

A bearing having at least two rubber bushings, each having a vertical axis of rotation, the rubber bushings being functionally connected in parallel.

A bracket-equipped vibration-damping device including: a vibration-damping device main body including vertically-separated, elastically-connected first and second mounting members; a bracket receiving the device main body inserted laterally thereinto; a connection-insert section provided for the second mounting member; a connection groove provided for the bracket extending in an insertion direction of the device main body; at least one up-down urging rubber fixed on an outer surface of the connection-insert section on an upper-lower first side; and a lock protrusion formed on an inner surface of the connection groove on an upper-lower second side, with a smaller protrusion dimension than an up-down thickness of the up-down urging rubber such that the connection-insert section is laterally inserted into the connection groove beyond the lock protrusion before being urged to the second side by the up-down urging rubber to be positioned to the connection groove.

A compressible liner for a helmet or other apparatus subject to shock loading comprises three substantially co-extensive layers mutually engaged by respective cone-like protuberances and cone-like recesses. The intermediate layer is of a different compressibility and provides for de-coupling of the layers in an oblique impact.
