A connector for connecting two structural components. The connector has a casing engaged and to move with a first of said structural components. The casing is of an elongate constant cross section interior within which is operative in a frictional sliding engagement a spring and damper assembly. This comprising of at least one damper to move with a second of said structural components and contacting the interior of the casing and able to slide in frictional contact with the casing. A spring is able to be elastically deformed by and between the damper and the casing when the damper and casing are in relative motion to bias the two structural components towards their initial relative position.

A steering column may include a steering spindle that is surrounded by a casing tube and is connected to a steering wheel, a guide clamp in which the casing tube is guided displaceably along a longitudinal axis of the steering spindle. The guide clamp may be mounted pivotably about a pivot axis in a holding part that is connectable to a chassis of the motor vehicle. The position of the casing tube may be adjustable relative to the holding part, and a blocking device may be arranged between the casing tube and the holding part. The blocking device may comprise a threaded rod engaged with a spindle nut. The spindle nut may be mounted in a rolling bearing. Rolling bodies of the rolling bearing may be at least partially surrounded by a magnetorheological fluid, and the blocking device may comprise an electromagnet.

A linear vibration damper and/or absorber includes a centre shaft (12) having bearing regions (18) and friction contact regions (20), and a housing (2) including finger assemblies (22) which are mounted with a small radial clearance for accurate location on the bearing regions (18) for axial displacement with respect to the centre shaft (12) along a central axis (X), the finger assemblies (22) each including resilient fingers (38) which extend axially from respective body sections (26) and have contact faces (40) which resiliently engage, i.e. are pressed by the resilience of the fingers (40) into contact with, friction surfaces (20) of the contact regions of the centre shaft (12), whereby relative linear displacement between the centre shaft (12) and the housing (2) is opposed by frictional contact between the friction surfaces (20) and the contact faces (40).

A frictional damper is designed with a tubular housing having a longitudinal axis, with a tappet, which is displaceable in the housing along the longitudinal axis and is led out at an open end of the housing, with a frictional element lying against the tappet and with a cap attached to the open end of the housing with axial prestressing relative to the longitudinal axis.

A damper includes a cylinder, a rod including a first engaging portion at a tip end thereof, and a piston formed of an elastic resin material. The piston includes a convex portion provided so as to protrude at a base end portion located on a rod base end side and always in pressure contact with an inner circumference of the cylinder. During damper braking, the first engaging portion of the rod abuts against the other end portion of the piston, and an axial compression force acts on the piston between the first engaging portion and the convex portion in pressure contact with the inner circumference of the cylinder.

A damping device with a fixing structure includes a housing and a valve stem which extends through the housing. The inner housing plate is disposed in the housing, and the inner housing plate separates a space in the housing to be a first housing chamber and a second housing chamber which are independent and communicated with each other. An end of the valve stem is in sliding and sealing fit with the first housing chamber, and the valve stem separates the first housing chamber to be two independent sub-chambers with variable volumes. A plunger rod is directly or indirectly slidably sealed on the plug hole. The powerhead assembly is configured to drive the plunger rod to move. The housing is separated to be two chambers The plunger rod is moved to communicate or block the damping liquid, which realizes two functions of damping and supporting.

A damper includes a piston provided with a rod, and a housing storing the piston, and generates a braking force by an operation of the piston. The piston includes a seal member relative to an inner wall of the housing; and a slider contacting the inner wall of the housing with a predetermined frictional force. When the braking force is generated, the slider presses against the seal member, and a portion contacting the inner wall of the housing in the seal member deforms toward an outside of the housing. At an inner side of the portion contacting the inner wall of the housing in the seal member, a deformation control portion is provided, which suppresses the seal member from deforming toward an inside of the housing.
