Abstract: A wind deflector for a motor vehicle roof which is movable between a rest position and an operating position, the bearing means containing a spring arrangement which pretensions the wind deflector into the raised operating position. The spring arrangement has a first range of motion of low spring force and a second range of motion of higher spring force, which are assigned to a first adjustment region of the wind deflector out of its raised operating position and a second adjustment region of the wind deflector into its lowered rest position. The wind deflector is lowerable in the range of motion of low spring force by the force of the head wind and in the second range of motion of higher spring force the actuating means with an adjustment force which exceeds the force of the head wind is active for lowering the wind deflector.

Abstract: To prevent soiling of a hearing aid, the latter is provided with an exchangeable ear wax guard which, in the area of the sound outlet opening of the hearing aid, can be inserted into a sound tube. The ear wax guard is characterized in that, in order to improve its securing in the sound channel, it is provided with elevations at least in a subarea of its surface. On the surface of the ear wax guard, the density or size of the elevations preferably increases counter to the direction of insertion of the ear wax guard.

Abstract: An extension spring strut comprises a pre-loaded extension spring with a damper disposed therein. An operating element is disposed inside the extension spring, having an actuating tappet that is joined to an end of the extension spring. The actuating tappet is displaceable over a total range of travel that includes a damping range of the piston rod of the damper and a no-load range of the actuating tappet.

Abstract: A damper comprises a piston rod which is disposed along a central longitudinal axis and extended out of an end of a casing through a guide and seal unit. A piston assembly on the end, inside the casing, of the piston rod divides the interior of the casing into two sectional casing chambers. A pressure-piston member and a traction-piston member of the piston assembly respectively comprise an flexibly deformable valve disk at a distance from their respective front walls. The piston assembly there-between comprises an annular piston which is movable relative to the piston rod along the axis between the valve disks in such a way that, by deformation conferred to the valve disk by the annular piston bearing against one of the valve disks, the valve disk rests on the associated piston member in such a way that a by-pass channel between the sectional casing chamber is at least narrowed.

Abstract: An adjustable-length gas spring comprises a housing and a piston rod led out of the latter, on which a piston is disposed, dividing the housing into two partial housing chambers. Provision is made for a valve for the partial housing chambers to be connected with each other, the valve comprising a valve-operating lever, which is arranged pivotably at right angles to its longitudinal direction and a valve seat of which, when the lever is pivoted out of a position of rest into a position of opening of the valve, can be lifted off a seal, while forming a gap that connects the partial housing chambers with each other.

Abstract: An adjustable-length column for chairs or the like has an upright tube and a pneumatic or hydropneumatic length-adjusting element arranged in the latter, the housing of the element being radially supported in the upright tube and displaceably guided in the direction of a common axis. A profile guarding against twisting is tightly arranged on the housing in particular by shrinking and has at least one radially projecting web which extends parallel to the axis and engages with a groove-like recess of a guide which is non-rotatably connected with the upright tube.

Abstract: In the case of a longitudinally adjustable gas spring with two tubes enclosing each other concentrically and with a valve at one end and with a relief channel at the end where the piston rod exits the inner tube consists of plastics material. It has groove-like channels on its external wall which connect the relief channel with the valve. The webs between adjacent channels bear against the internal wall of the outer tube. The result is a cost-saving structure of the inner tube, which at the same time becomes very stable and is easy to manufacture.
