Abstract:
A method for producing an adjustment fitting, particularly for a vehicle seat is provided, whereby an outer wheel is associated with a first fitting part, the wheel having inner toothing, and having an inner wheel that can be associated with a second fitting part, the wheel having outer toothing, wherein the inner wheel having the outer toothing is inserted into the outer wheel having the inner toothing eccentrically to a rotational axis in the manner of a wobble mechanism, wherein partial eccentric elements are inserted rotatably with respect to each other in an eccentric receiving chamber formed between the rotational axis and the inner wheel so as to produce variable eccentricity, wherein a transmission element having an engagement element for actuating the partial eccentric element is inserted such that the engagement elements interacts with a catch of the partial eccentric element. In spite of the production tolerances of the components, overall higher quality and higher operational safety of the produced adjustment fitting are to be achieved. For this purpose, the geometry of the partial eccentric element is measured, and the geometry of the transmission element is individually adapted according to the data of the measurement before inserting the transmission element.
Abstract:
A decoupling element for a conduit includes an interior hose made of metal and a corrugated exterior hose surrounding the interior hose, with a hollow-cylindrical gap formed between the corrugated exterior hose and the interior hose. At least one damping element is arranged in the gap, with the damping element(s) constructed of a woven fabric made of a high-temperature-resistant material and having an outside surface with at least one bulge, wherein the bulge positively engages with a corrugation of the exterior hose. The exterior hose may be a membrane bellows. The woven fabric may be a metallic material. The at least one damping element covers, along the rotation axis, preferably a proportional length of at least 20% of the hollow-cylindrical gap and has preferably a static stiffness in the radial direction of less than 100 N/mm.
Abstract:
Adjustment fitting, in particular for a vehicle seat, comprising a first fitting part and a second fitting part that can be rotationally adjusted relative to the first fitting part about an axis of rotation. An external gear, which has internal teeth and into which an internal gear that is associated with the second fitting part and has external teeth is inserted like an eccentric gear, is associated with the first fitting part. The internal gear forms an eccentric receiving space towards the axis of rotation. The adjustment fitting further comprises an eccentric member that is rotatably inserted into the eccentric receiving space and is equipped with a drive shaft for driving the eccentric member, and a cap for covering the open receiving space. The cap is eccentrically designed relative to the axis of rotation, penetrates into the eccentric receiving space by means of an axially downward-pulled sealing edge, and seals the receiving space as the sealing edge is preloaded in a radially outward direction. The adjustment fitting is easy to mount, while the cap ensures a secure sealing action regardless of the axial height of the adjustment fitting.
Abstract:
A power switch includes switch contacts that are opened via a switch shaft, which, when the switch is triggered, is actuated by way of the trigger slider of a trigger unit, in particular a working current trigger unit. The trigger slider moves the switch shaft by way of the trigger shaft of a switch latch, the trigger unit including electric coil into which an armature extends that is drawn into the coil by electromagnetic forces of attraction when the switch is triggered. A stationary counter armature is disposed in the coil, which counter armature serves as a stop for the armature, so as to increase the forces of attraction. The movement of the armature is transmitted by way of a mechanism to the movement of the trigger slider so as to increase the displacement path of the trigger slider.
Abstract:
The fluorine surfactant-free, long-term-stable and biodegradable additive for chromium electrolytes lowers the surface tension and hence improves the chromium deposition process, especially in the application for the electrolytical chromium-plating. Preferred additives are CH3(CH2)nSO3H and the salts thereof with n from 10 to 18. These additives are also useful as component in polymer mordants as pretreatments for polymer metallizations.

The external gear is designed as a ring gear that has a bottom and an external wall which axially extends beyond the internal teeth. Furthermore, a holding element is provided which can be axially slid against the internal gear in the external wall, is mounted on the external wall, and secures the internal gear against the bottom of the ring gear. The holding element allows the axial tolerance between the internal gear and the external gear to be adjusted.

In addition, the internal gear comprises an internal wall which axially extends beyond the external teeth and axially penetrates the collar. The fitting parts are thus securely fastened in the axial direction while access is made easy, especially for mounting the adjustment fitting on a vehicle seat or a seat adapter.
Abstract:
A diaphragm bellows includes a spiral-wound, pre-profiled metal strip having neighboring turns which are connected by a continuous welding seam in an area of an outer diameter or inner diameter of the metal strip. Neighboring flanks of the metal strip enter a region of the welding seam at an angle of less than 60°.
Abstract:
A tube is made of profiled metal strip which includes an end leg extending in parallel relationship to a tube axis, an inner leg extending in parallel relationship to the tube axis at a first distance, and an outer leg extending in parallel relationship to the tube axis at a second distance which is greater than the first distance. The inner leg is connected with the outer leg by a transition. A double-folded loop hook extends radially for connecting the end leg with one member from the group consisting of the inner leg and the outer leg, and an end hook extends radially and is connected to the other member of this group.
Abstract:
The invention relates to a method for producing a pipe element (1) for pipes that are subject to vibrating stress, especially for exhaust pipes in motor vehicles. Said pipe element consists of a preprofiled strip (2; 3), especially a metal strip, that is wound in convolutions with bellow-shaped windings (4; 22). The wound layers produced by a strip width are interlinked in a single-hooked or multi-layer clasp-type bond (9; 19) by positive locking, welding or similar joining methods. The Strip (2; 3) is preprofiled with at least one stitch that is off-set from the plane by deflection into a kind of circuit with web heights (h1, h2) of the bellows (4; 22) that are multiples of the strip thickness.
