A crash box may include one or more layers arranged to absorb crash energy. In some embodiments, the crash box includes a first layer having an outer skin defining a periphery of the first layer and at least one of: 1) a rib and web structure, and 2) an array of tubes disposed within the outer skin for absorbing crash energy, and a second layer adjacent to the first layer, the second layer having an outer skin defining a periphery of the second layer and at least one of: 1) a rib and web structure, and 2) an array of tubes disposed within the outer skin for absorbing crash energy.

The invention relates to a hydropneumatic suspension component such as a gas charged damper. The invention further relates to a floating piston for a hydropneumatic suspension component. Uses of adsorbent material and/or open-cell foam are also disclosed.

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 invention concerns a suspension thrust bearing for use with a suspension spring in an automotive suspension strut. The suspension thrust bearing provides a bearing with an annular upper part and a annular lower part in relative rotation one to the other, a lower support surface being provided by the lower part that axially supports an upper end of a suspension spring by the intermediate of a damping device made from resilient material. The resilient material of the damping device is molten in its preformed state with gas. After being molded, the molten material of the damping device provides an outer skinny layer and an inner foam body, the density of the outer skinny layer being strictly greater than the density of the inner foam body.

Disclosed herein is a haptic device having at least one vibration motor, such as a linear vibration motor, configured to selectively generate a vibration at least partially along an actuator axis. An interfacing plate is configured to transmit the vibration and is at least partially composed of a compliant material. The linear vibration motor and the interfacing plate are embedded in a host. The host defines a first surface with a recessed zone extending from the first surface. The interfacing plate is configured to fit in the recessed zone. The host includes a chamber contiguous with the recessed zone, with the linear vibration motor being positioned in the chamber. The chamber may include respective walls having a plurality of protrusions configured to at least partially absorb the vibration. The haptic device may be part of a seat assembly.

An apparatus for supporting a flexible conduit which includes a flexible member and a rigid member in fluid communication with the flexible member. The apparatus has a releasable connector and a shock absorber. The releasable connector has a first member and a second member. When a releasing force is applied to the flexible conduit, the releasable connector separates. The shock absorber is configured to absorb a load when the releasable connector separates. The shock absorber may include a compressible material that includes a metal, such as a metal foam or a corrugated metal sheet. The releasable connector and the shock absorber may be integrally formed together.

A shock-absorbing face guard connector for an athletic helmet such as a helmet worn in American football, ice hockey, cricket, and baseball and softball, among other possible applications. The shock-absorbing face guard connector couples a face guard to the athletic helmet, and can absorb some of the forces resulting from a strike or impact to the face guard amid play and at other times. The shock-absorbing face guard connector includes a compressible piece that can compressibly yield when the face guard is struck or otherwise impacted.

A force damper arranged to progressively arrest a first force imparted by an object moving in a first direction is disclosed. The force damper includes a housing enclosure having a first housing end and a second housing end. The first housing end includes a first connection point, and the second housing end includes an opening. A driving member is disposed within the housing enclosure and includes a first shaft end, a second shaft end, and a shaft therebetween. The first shaft end includes a stop and the second shaft end includes a second connection point. A compressible member is disposed within the housing enclosure between the stop and the opening. The compressible member is formed from a material that at least partially undergoes plastic deformation when the first force is arrested and imparts a second force on the stop toward first housing end.

A machine includes a section that defines a target vibrational mode to dampen and a nanocellular foam damper that includes interconnected ligaments in a cellular structure. The interconnected ligaments have an average ligament size defined with respect to a vibrational loss modulus of the nanocellular foam damper and the target vibrational mode. Also disclosed is a method of damping vibration.

The invention relates, inter alia, to an inflatable shock-absorbing cellular structure (1) which consists of two sealed sheets (10, 11) welded together along weld lines (100) that define inflatable cells (2), said inflatable cells (2) being arranged according to at least one two-dimensional matrix (MA) of n rows (L1-L6) and m columns (C1-C6) of cells (2), n and m being the same or different integers, each greater than or equal to 2, a peripheral cell (2) of the matrix (MA) being connected to an inflation nozzle (4). Said structure is characterised in particular in that: —the cells (2) are not contiguous; —the cells (2) of the row and/or column to which the peripheral cell (2) connected to the inflation nozzle (4) belongs communicate with one another through a channel (3) forming a constriction, while each remaining cell (2) of the matrix (MA) is also connected to at least one of the neighbouring cells (2) of the same row and/or the same column through a communication channel (3) forming a constriction.
