An impact absorber absorbs impact energy when receiving an impact load. The impact absorber includes a fibrous structure. The fibrous structure includes a tube of which a center axis extends in a direction in which the impact load is applied and a rib that connects opposing inner surfaces of the tube. The fibrous structure is impregnated with a matrix resin. The direction in which the impact load is applied is referred to as an X direction, and a direction in which the rib connects the opposing inner surfaces of the tube is referred to as a Y direction. The tube includes a fiber layer including load direction yarns extending in the X direction and intersecting direction yarns intersecting the load direction yarns. The rib includes yarns extending only in a direction orthogonal to the X direction.

An energy-absorbing member includes a fiber structure. The fiber structure includes a first end face configured to first receive a load and a second end face opposite to the first end face in the direction that the load is applied. The fiber structure includes a shape retention section including the first end face, a main section that includes the second end face and hinders propagation of breakage of the fiber structure, and a trigger section that is located between the shape retention section and the main section and serves as a starting point of breakage when receiving an impact load. The shape retention section and the main section each have a woven structure that allows the shape retention section and the main section to have a higher interlayer bonding strength than the trigger section.

These teachings relate to a device that includes a base having an axis that is centered and perpendicular relative to the base and two or more arms each connected to the base at a base hinge The base hinge rotates the two or more arms away from the axis, and one or more expandable bands are connected with distal ends of the two or more arms. The one or more expandable bands absorb energy from rotating of the two or more arms. The device absorbs energy when an external force is applied along the axis of the base.

A system for amplifying haptic effects provided by a push-pull actuator includes a housing component, a push-pull actuator coupled to the housing component and configured to provide a force and a displacement, a lever component including a lever arm and a fulcrum, and a haptic touch surface coupled to the lever arm via an output interface. The push-pull actuator is via an actuator mount. The amount of displacement transferred to the haptic touch surface from the push-pull actuator is reduced by the lever component and the amount of force transferred to the haptic touch surface from the push-pull actuator is increased by the lever component. The system may include a material stop coupled to the housing component that when compressed by the haptic touch surface exhibits hysteresis to dampen the haptic touch surface.

Implementation described and claimed herein include a cushioning structure and method for manufacturing a cellular cushioning system, which allows for maximum comfort through the compression and shock cycle. Specifically, a cushioning structure comprises void cells formed in an array, which comprise multiple outwardly curved surfaces, with varying radius measurements. Stiffness in the void cells can vary by varying the Radii. Outwardly curved surfaces prevent buckling and provide support for high impact by absorbing energy.
