This coil spring has a part of high hardness and a part of lower hardness than the part. Also, it is preferable that the hardness of the part that comes into contact with other members is lower than the hardness of the part other than the part that comes into contact with the other members. Moreover, it is preferable that the hardness of an end turn part of the coil spring is lower than the hardness of the part other than the end turn part. Furthermore, it is preferable that the hardness of the part that comes into contact with a receiving member adapted to receive the end turn part of the coil spring is lower than the hardness of the part other than the part that comes into contact with the receiving member.

Extension for a cylinder of a vibration damper comprising a base and a tube portion adjoining the latter. The base and the tube portion are formed in one piece. The tube portion has a circumferential bend pleat with respect to the base.

Disclosed is a method of manufacturing a final piece including several materials, the final piece being produced at least according to the steps of: inserting an elastomer (5) in at least one insertion cavity (6) of an initial piece (2) so that the elastomer (5) is in contact and fixed with the initial piece (2); then cutting the initial piece (2) in at least two distinct parts (3, 4), so that the at least two distinct parts (3, 4) are fixed together but not in contact with each other, the at least two distinct parts (3, 4) being connected together by the elastomer (5). This may be applied to manufacturing a final piece including several parts, of various natures, connected together.

The flocked helical spring includes a spring body, a cationic electrodeposition coating layer disposed on the surface of the spring body, an adhesive layer disposed on the surface of the cationic electrodeposition coating layer, and a flocking layer composed of flocking fillers fixed to the adhesive layer. The surface roughness Rz of the cationic electrodeposition coating layer is 19.6 ?m or greater. The method for producing a flocked helical spring includes a cationic electrodeposition coating process of performing a cationic electrodeposition coating treatment on a spring body to form a film of an electrodeposition coating material on the surface of the spring body; an adhesive coating process of coating an adhesive containing a surface roughening solvent on the surface of the film; a flocking process of bonding flocking fillers to the surface coated with the adhesive; and a baking process of heating the spring body adhered with the flocking fillers.

The invention relates to a damper bearing comprising a hollow housing (1) for receiving a damping element (5) and a cover (3) for fixing the damping element (5) in the housing (1), wherein the housing (1) and the cover (3) are manufactured from plastic and the connection between the housing (1) and the cover (3) is produced integrally by a welding process, which is based on a relative movement between the housing (1) and the cover (3). The invention furthermore relates to a method for producing a damper bearing according to the invention, in which the housing and the cover are brought into contact at contact surfaces provided for this purpose, and a relative movement between the housing and the cover is then generated, which causes the housing and the cover to be integrally welded as a result of the energy input into the contact surfaces.

Provided is a plate spring fixing structure and the like which do not necessitate complex assembling processes and thus can reduce production cost and can be reduced in size, and which enable adjustment, during a production process, of the extent to which the plate spring is bent. A holding structure (1A) includes a first plate spring (12) that has: a fixed portion (12a) embedded in and fixed to a first molded resin part (11); and a spring portion (12b) which is not fixed and which has a spring property. The fixed portion (12a) has a face that is not in contact with the first molded resin part (11).

An axially damping elastomer bearing suitable for a motor vehicle, with a crucible-formed receptacle (13) for surrounding receiving an elastomeric support spring (15). The crucible-formed receptacle (13) is manufactured through casting and can be demolded in a demolding direction (39) and has a peripheral wall (19) with at least one drainage opening (33), wherein the at least one drainage opening (33) has a clearance (43, 45, 65) extending in the demolding direction (39).

A sole structure for an article of footwear includes an impact-attenuation support member. The impact-attenuation support member includes a first impact-attenuation element and a second-impact-attenuation element. The first and second impact-attenuation elements include one or more portions that are interlinked and that are movable with respect to one another in at least one direction.

This invention relates to a support pad formed of a shock absorbing material capable of absorbing energy resulting from vibration and gravitational forces acting on a battery disposed in engagement with the support pad and, correspondingly, transferring gravitational forces that occur along a z-axis resulting from up and down movement of the battery and dispersing these gravitation forces along an x-axis, a y-axis and the z-axis so as to reduce the impact shock on the battery by between about 65% to about 80% and, in doing so, prolonging the performance and life-cycle of the battery.

A vibration reduction damper is disposed inside a center vent tube having vent holes which pass therethrough in the radial direction, and has a sliding portion which comes slidably into contact with the inner wall surface of the center vent tube while avoiding the region in which the vent holes are formed.
