Abstract:
A door closer is described in which transmission ratios which change in dependence on the closing angle can be realized by eccentric toothed elements. The toothed elements can have different profile offsets, moduli and flank angles along their respective pitch curves.
Abstract:
A laterally releasable toe unit has two laterally pivotable side jaws (11) which are held in a ski boot retaining position by a yoke (26) on which a release spring (30) acts and which can be pivoted laterally while pushing the yoke rearwardly against the spring force to release the ski boot. A toe plate (15) which is movable by a small amount in a vertical direction is arranged behind a laterally fixed toe restrainer (13) and generates, via a force deflection transmission, a longitudinal force which is dependent on the contact force which acts on the toe and which counteracts the spring force via a bar member (12). At least one lever (14) which is acted on by the vertically displaceably or pivotably arranged toe restrainer (13) acts on the same bar member (12) in the same sense with a release force which is dependent on the vertically upwardly directed force acting on the toe restrainer (13).
Abstract:
In a force transmission system with a wrapping spring-type wraparound element and with a frictional surface assigned to the wraparound element, a switching device is provided for switching the wraparound element between two switching states is provided. In the first switching state, the wraparound element is operatively connected in a force-transmitting manner to the frictional surface. In the second switching state, it is operatively connected thereto in a non-force-transmitting manner. In the second switching state, the wraparound element is fully lifted off the frictional surface. The force transmission system is suitable in particular for a drive system of an adjusting element of a motor vehicle.
Abstract:
A manual adjustment of a back support on a vehicle seat includes a cable pulley which is selectively rotatable in a drive direction or in a driven direction oriented counter to the drive direction, and a tensile device associated with the cable pulley, which may be rolled up onto the cable pulley by rotating the cable pulley in the drive direction. The tensile device is able to be coupled to a back support of a vehicle seat such that the rotation of the cable pulley in the drive direction and/or driven direction affects an adjustment of the back support. A pretensioning acts on the cable pulley -which produces a torque of the cable pulley in the driven direction.
Abstract:
A motor vehicle seat back structure comprising a backrest support frame which consists of a surface turned towards the seat user's back, a lordosis support which is arranged on the front part of the backrest support frame for supporting the user's back and an adjusting device for vertically adjusting the lordosis support position with respect to the extension plane of said backrest support frame. The adjusting device comprises at least one adjusting element operably connected to the lordosis support and at least one sliding element which is displaceable with respect to said adjusting element and interacts therewith in such a way that when the sliding element moves, the adjusting element is displaced with a directional component perpendicularly to the displacement direction of the sliding element and performs an action on said lordosis support in the direction.
Abstract:
A double-acting drive for adjustment devices in motor vehicles comprises: a drive element which is turnable or rotatable in the one or the other direction about a drive axis; an output wheel which is connected to the adjustment device, is adjustable in its angle and comprises a rotationally symmetric inner wall; and a band-shaped coupling element, which is arranged in the force flow between the drive element and the output wheel, is braced with the rotationally symmetric inner wall of the output wheel and carries along the output wheel in circumferential direction if the drive element is moved from a starting position in the one or the other direction. The ends of the band-shaped coupling element overlap each other and form coupling levers which run secant-shaped on both sides of the drive axis and which are carried along by the drive element in dependence on the rotational direction of the drive element for expanding and bracing the band-shaped coupling element with the rotationally symmetric inner wall of the output wheel and which abut on support noses of the band-shaped coupling element, the support noses being arranged substantially perpendicular to the coupling levers.

Abstract:
An adjusting system of a motor vehicle for the adjustment of a closing part is disclosed. The system includesa first and second casing extending oblong in a length-wise direction. The second casing has a smaller cross section than the first casing and is arranged within the first casing to be adjustable in a length-wise direction. A spindle for the relative adjustment of a first casing to the second casing is included and arranged within either or both of the first and second casings.The system also includes an electromotor and a transmission connected with either or both of the spindle and second casing. In addition, at least one spring is arranged within either or both of the first and second casings and operates length-wise, such that one of the casings is attached on the side of the motor vehicle body and another of the casings is attached to the closing side.
Abstract:
A drive which operates on both sides for use in adjusting devices, such as motor vehicle seats, includes a drive lever, a drive wheel, and coupling elements. The pivotally mounted drive lever is for, starting from an initial position, effecting a turning movement in one direction or the other as desired. The drive wheel is turned when the drive lever is moved out of the initial position. The coupling elements are arranged on the drive lever and have coupling areas for transmitting a turning movement onto the drive wheel. In order to transmit a turning movement, the coupling element can be coupled to the drive wheel via at least one positive locking element and by at least one elastic element.
Abstract:
A manual passive continuous action quick adjustment device for adjusting elements in or on motor vehicles without a separate drive unit comprises a worm rotatably disposed within a housing. The worm comprises a locking region that is configured to engage a locking element disposed within the housing. The worm comprises a toothed section that is threadably engaged with a toothed section of an oppositely oriented toothed segment lever that is connected to the particular device requiring adjustment. The locking region may comprise a circumferential groove near an end portion of the worm and the locking element may comprise a slide configured to accommodate frictional engagement with the groove. The locking region may comprise the front faces of the toothed section of the worm frictionally engaged by a slide. A second locking region may comprise front faces adjacent to ends of the worm frictionally engaged by edge portions of the housing upon radial displacement of the worm by activation of the slide. Alternatively, the toothed segment lever or worm itself may comprise an eccentric member that when activated causes either the lever or worm to be displaced towards one another to block rotational movement of the worm.
