A damper is disposed in a holding hole that passes through, in a passing-through direction, a supported member that is supported by a supporting member. The dumper includes a tubular body defining therein a through hole extending in the passing-through direction. The tubular body is elastically deformable between a first form and a second form. The tubular body in the first form has an outer shape that is smaller than the holding hole. The tubular body in the second form has an outer shape that is equal to or greater than the holding hole.

Composite springs, composite spring assemblies, medical devices including the same, and methods of making and using the same are disclosed. The composite springs may comprise alternating layers of carbon fiber and fiberglass materials. A strengthening adhesive, such as an epoxy, may be used to bind the carbon fiber and fiberglass materials. A dampening member may be attached to the composite spring, thereby at least partially defining a composite spring assembly. The dampening member may dampen elastic/spring forces of the composite spring. The composite spring assembly may be attached to an orthotic device to provide a non-linear spring response during movement of the device.

A vehicle seat assembly includes a seat frame, a seat pan, and a plurality of vibration isolators interposed between the seat frame and the seat pan for limiting transmission of vibrations from the seat frame to the seat pan.

A vibration isolator includes a first conical disc spring member having a first end and a second end. A first-end spacer in contact with the first spring member first end, and a second-end spacer in contact with the first spring member second end. A second conical disc spring member has a first end and a second end. The second spring member first end is in contact with the first-end spacer. Another second-end spacer is in contact with the second spring member second end. A flexible housing of the isolator defines an interior. The housing is in contact with and extends between the second-end spacer and the other second-end spacer so that the first-end spacer and the first and second spring members are received in the housing interior. The housing includes a plurality of spaced-apart through holes formed therealong between the second-end spacer and the other second-end spacer.

Gas spring assemblies include a flexible spring member and a restraining cylinder. The flexible spring member includes a flexible wall extending longitudinally between first and second ends as well as peripherally about a longitudinal axis. The flexible wall includes an inside surface and an outside surface with the inside surface at least partially defining a spring chamber. The restraining cylinder includes a cylinder wall that extends longitudinally between first and second open ends as well as peripherally about the longitudinal axis. The cylinder wall includes an inside surface and an outside surface. The restraining cylinder is disposed longitudinally along the flexible spring member between the first and second ends thereof with at least a portion of the inside surface of the restraining cylinder permanently attached to the flexible wall along the outside surface thereof by way of a chemically-bonded joint. Methods of assembly are also included.

A stabilizer adhesive bearing for a vehicle stabilizer may comprise an annular sleeve having a resilient inner contour for coaxial arrangement on the vehicle stabilizer. The resilient inner contour of the annular sleeve may comprise on a side facing the vehicle stabilizer a three-dimensionally structured surface with an adhesive receiving volume. The three-dimensionally structured surface has a maximum roughness depth (R.sub.max) greater than 45 μm and a core roughness depth (R.sub.K) of at least 65% relative to the maximum roughness depth (R.sub.max) of the three-dimensionally structured surface. The maximum roughness depth (R.sub.max) is a total of the reduced tip height (R.sub.pk), the core roughness depth (R.sub.K), and the reduced groove depth (R.sub.vk). Further, the reduced tip height (R.sub.pk), the reduced groove depth (R.sub.vk), and the core roughness depth (R.sub.K) may be determined in accordance with EN ISO 13565-2: December 1997.

This spring used for a suspension device for a vehicle is provided with: a metal wire material which constitutes a spring section and which has a cover layer provided on the surface thereof; and a seat section which is subjected to a load acting on the spring section, is formed from an elastically deformable material, has a groove section into which the wire material fits, and is bonded to the wire material by an adhesive. The minimum thickness of the portion of the adhesive, which protrudes from the groove section, is greater than or equal to the thickness of an adhesion layer formed in the groove section.

A motor vehicle has a housing for an energy store arranged on a bottom side of a floor assembly of the motor vehicle such that the vibrations of the floor assembly are reduced. A damping component id provided as an elastomeric spring, the material properties of which exhibit, under dynamic loading, dynamic hardening, so that the stiffness under dynamic loading starting from a frequency of greater than 0.1 Hz is greater by a dynamic hardening factor, which is greater than 2, than the stiffness which is present under quasi-static loading, such as when fitted for example.

A damper unit for use in a vibration-reducing assembly for a steering wheel is disclosed. An elastomeric damper element is molded on an inner sleeve and includes a plurality of elastomeric ribs forming a radially outer engagement surface, and a plurality of elastomeric support studs, which are mutually spaced in a circumferential direction are flexible in all directions transverse to said axis. Methods for making a damper unit and a damper assembly are also disclosed.

A shock absorber having a metal damper tube and base assembly is provided. The base assembly, which includes a composite mounting attachment made of a composite material, such as a recyclable thermoplastic, is fixed to an external surface of the metal damper tube, which may be a finished product. A cavity in the composite mounting attachment houses at least a portion of the metal damper tube and thus defines an overlapping region where the composite mounting attachment and the metal damper tube are co-extensive with each other. One or more windows are provided in the overlapping region of the composite mounting attachment where the metal damper tube is left exposed. This helps to promote heat dissipation away from the metal damper tube while reducing weight and heat transmission from the metal damper tube to the composite mounting attachment to reduce overheating of the composite material.
