A stabilizer bushing installed on a stabilizer bar is made of two divided parts of rubber or the like to prevent or decrease generation of a gap in a bonding surface. The stabilizer bushing installed on an outer periphery of the stabilizer bar by adhesion includes divided rubber bushings of an upper rubber bushing and a lower rubber bushing. Before adhesion, both end portions of the upper and lower rubber bushings, respectively, in a circumferential direction are tapered so that an overlapping amount between the upper and lower rubber bushings increases toward the outer periphery side of the bushings. After adhesion, a bonding surface is bonded by pressure.

A constant force spring system to achieve a substantially constant force curve, includes top and bottom load surfaces separated by a load compression distance therebetween; a main spring; at least one auxiliary linear spring acting on a last portion of the load compression distance to prevent load compression; a spreading linkage acting between the top load surface and the bottom load surface to prevent load compression thereof; and link hinges connecting the links, wherein the spreading linkage.

Provided is a vehicle seat that facilitates setting of a starting load of a movable member. The vehicle seat includes a movable mechanism including: first and second springs coupled to a frame; a movable member displaceable relative to the frame; a first passive member and a second passive member coupled with the respective first and second springs; and a restriction member configured to restrict displacement of the first and second passive members. The movable member displaces the first passive member in a first direction when the movable member is displaced in the first direction, and displaces the second passive member in a second direction when the movable member is displaced in the second direction. The restriction member restricts displacement of the first passive member from a first-passive-member initial position in the second direction and displacement of the second passive member from a second-passive-member initial position in the first direction.

The present invention is a vibration damping device (1, 2) that includes an external member (11, 21) attached to one of a vibration-generating portion and a vibration-receiving portion; a tubular member (40) attached to the other of the vibration-generating portion and the vibration-receiving portion; and an elastic body (30) which connects the external member (11, 21) and the tubular member (40). The external member (11, 21) includes a frame-like member (11, 21) having a rectangular shape when viewed from the top. In the elastic body (30), a long-side portion (32a) forming a long side of a rectangular shape when viewed from the top adheres to an inner circumferential surface of the long-side portion (12a, 12b) of the frame-like member (11, 21), and a short-side portion (32b) forming a short side of the rectangular shape when viewed from the top comes into contact with the external member (11, 21) in a long-side direction (X) in which the long-side portion (12a, 12b) extends when viewed from the top, in a non-adhering state.

A damper device (100), for damping the movement of a component, has a device housing (110) and a spring (120) which is fastened by a first end (121) to the device housing (110) and by a second end (122) to a driver element (140). The spring, in a tensioned state, pretensions the driver element (140) in terms of rotation. The driver element (140) is designed such that, during a rotational movement about an axis of rotation, it carries along a pivoting element (150) and, in the process, sets the latter into a rotational movement about the axis of rotation relative to the device housing. The pivoting element is connected to a damper (130). The damper device has a stop element (111) which is designed such that it restricts or limits the rotational movement of the driver element without restricting or limiting the rotational movement of the pivoting element.

A turnbuckle-style support strut with tunable stiffness, wherein the turnbuckle-style support strut uses opposing stacks comprised of one or more Belleville spring washers to provide the tunable stiffness to support a given application.

Methods and apparatus of a system for vehicles comprising a vehicle suspension, a sensor operable to measure an operational characteristic of the vehicle suspension, and a processor in communication with the sensor that is operable to suggest an operational setting of the vehicle suspension in response to an input from the sensor corresponding to the operational characteristic. A method for adjusting a suspension of a vehicle may comprise receiving suspension data with a processor, calculating a suspension setting suggestion with the processor, communicating the suspension setting suggestion to a user interface device, and adjusting the suspension based on the suspension setting suggestion.

The present invention relates to a return system (10) intended to equip a hooking device comprising a housing and a load hook (30) mounted so as to be able to pivot relative to the housing, the return system being mounted between a rod (21) secured to said housing, and comprising at least one tension spring (11), a device for adjusting the force of each tension spring with a plate (12) and a connecting rod (13) adjustably attached to the plate, and a crank pin (14) situated at a free end of the connecting rod, each tension spring links the rod to said plate, the crank pin is attached to the load hook, and the return system exerts a return force on the load hook that allows said load hook to close. The present invention also relates to a hooking device equipped with such a return system.

A spring system that includes an adjustable spring system that is operated by a motor.

A passive variable negative stiffness device (passive VNSD) configured to facilitate a transition to zero stiffness by using elastic devices (e.g., springs) combined with translating and rotating components. An exemplary embodiment of a passive VNSD may comprise at least one pretensioned and/or precompressed elastic device to produce the desired force-displacement profiles. For instance, an exemplary embodiment of a passive VNSD may be adapted to produce force-displacement profiles that transition from zero stiffness, to negative stiffness, and then to positive stiffness (ZNP) and from zero stiffness, to negative stiffness, and then back to zero stiffness (ZNZ).
