An energy absorbing structure includes a base, a loading platform, a pair of side supports, a center support, and a pair of flexible segments. The loading platform is spaced apart from the base. The side supports project from the base toward the loading platform. The center support projects from the loading platform toward the base. The flexible segments extend from the side supports to the center support and connect the side supports to the center support. The flexible segments have straight edges and curved surfaces disposed between the straight edges. The straight edges extend from the side supports to the center support and are oriented at an oblique angle relative to the base. Each of the curved surfaces faces one of the base and the loading platform.

This invention relates to a damping device for mounting two separate components for damping oscillations between the components, wherein the damping device has an axial damper that comprises a first connecting element as well as a second connecting element, wherein the first connecting element is connected to the second connecting element via a damping section by ensuring an axial relative movement of the two connecting elements with respect to one another, wherein the damping section is designed for damping the axial relative movement between the connecting elements.

The invention relates mainly to an energy absorber for an aircraft seat, notably for a helicopter seat, comprising at least one energy-absorption element having: a first anchor point and a second anchor point, an energy-absorption zone extending between the first anchor point and the second anchor point, said energy-absorption zone being able to stretch as a tensile load is applied between the first anchor point and the second anchor point, characterized in that the energy-absorption zone has a meshed structure comprising a plurality of strands connected to one another by junction portions, and in that at least one junction portion provides a junction between at least three strands of said energy-absorption zone.

An improved shock isolating mounting comprising at least three substantially U-shaped leaf spring members, each leaf spring member comprising at least two leafs arranged to define a space therebetween. In one arrangement, the respective at least three substantially U-shaped leaf spring members are arranged in an array having a substantially equal angular spacing between adjacent spring members.

A suspension system for a vehicle is provided. The suspension system includes a first chassis rail extending longitudinally in an axial direction of the vehicle. The suspension system also includes a second chassis rail extending longitudinally in the axial direction of the vehicle. The suspension system further includes a transverse beam coupled to the first chassis rail and the second chassis rail. The suspension system yet further includes at least one leaf spring extending in a transverse direction of the vehicle, the at least one leaf spring having a spring rate that is actively variable. The suspension system also includes a fulcrum locator operatively coupled to the at least one leaf spring and to the transverse beam, the fulcrum locator in a sliding relationship with the at least leaf one spring.

A hinge device for supporting a display device is provided. The hinge device comprises a supporting seat, a shaft, a bearing plate, and an elastic module. The shaft rotatably passes through the supporting seat. The bearing plate is disposed on the shaft, and the display device is disposed on the bearing plate. The elastic module includes a cam and at least one elastic plate. The cam is configured on the shaft, and the cam and the shaft rotate synchronously. A fixed end of the elastic plate is fixed to the supporting seat. The elastic plate has a deformation amount to provide a balance torque to the cam when a free end of the elastic plate abuts against the cam. When an external force is applied on the display device, the bearing plate is actuated to drive the shaft and the cam to rotate to change the deformation amount and the balance torque of the elastic plate. When the external force is removed, the display device can be stopped at once.

A device for applying an axial force includes a longitudinal axis with a first compression surface located at a first end of the longitudinal axis and a second compression surface located at a second end of the longitudinal axis. A plurality of resilient members is positioned between the first compression surface and the second compression surface. A first resilient member is oriented with a first end proximate the first compression surface and a second end proximate the second compression surface. A second resilient member is oriented with a first end proximate the first compression surface and a second end proximate the second compression surface. The device has a compressed state and an expanded state where the first compression surface and second compression surface move in a direction of the longitudinal axis between the compressed state and the expanded state.

A Belleville washer with interlocking teeth to allow one washer to firmly lock to an adjacent washer, positioned in series, allowing for assembly of a modular-type stackable spring, without need of a bolt for retention of washer alignment.

A planar spring has an outer ring, an inner ring, and two elastic components. The inner ring is disposed in the outer ring, and forms a space therebetween.
