Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein stufenlos arbeitendes Schrittschaltwerk, welches insbesondere zur Verstellung eines Kraftfahrzeugsitzes geeignet ist.The The invention relates to a continuously variable indexing mechanism, which is particularly suitable for the adjustment of a motor vehicle seat is.
Hintergrund der ErfindungBackground of the invention

Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein stufenlos arbeitendes Schrittschaltwerk mit einem besonders robusten, kompakten und montagefreundlichen Aufbau anzugeben.Of the Invention is based on the object, a continuously working Stepping mechanism with a particularly robust, compact and easy to install Structure to specify.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Schrittschaltwerk mit den Merkmalen des Anspruchs 1. Dieses insbesondere für einen Verstellmechanismus eines Fahrzeugsitzes geeignete Schrittschaltwerk umfasst einen begrenzt schwenkbaren Außenring und einen Innenring, welche einen Ringraum begrenzen, in dem Klemmelemente, insbesondere Klemmrollen, angeordnet sind. Der Außenring ist in beide Drehrichtungen verschwenkbar, wobei er durch Federkraft mit einem Drehmoment in Richtung zu einer zwischen zwei Extrempositionen liegenden Neutralposition belastet ist. Die Rückstellung des Außenrings, mit welchem typischerweise ein Schwenkhebel drehfest verbunden ist, in die Neutralstellung wird bewerkstelligt durch ein Federelement, welches als um den Außenring gewickelte Drehfeder ausgebildet ist, wobei die Enden der Drehfeder in den Ringraum eingreifen und dabei mit einem die Klemmelemente führenden Käfig zusammenwirken. Jedes Klemmelement ist vorzugsweise in beiden Drehrichtungen wirksam, wobei das Klemmelement in Neutralstellung des Außenrings mittig in einer Doppelklemmrampe angeordnet ist. Die Klemmrampenkontur ist bevorzugt an der inneren Oberfläche des spanabhebend aus Metall hergestellten Außenrings gebildet, während der Innenring eine durchgehend zylindrische Außenoberfläche aufweist. Der Innenring ist besonders rationell als spanlos umgeformtes Blechteil herstellbar und kann einstückig mit nach innen gerichteten Mitnahmeelementen, beispielsweise für einen Schaltkäfig, ausgebildet sein.These The object is achieved by a stepper with the features of claim 1. This in particular for an adjustment mechanism of a vehicle seat suitable stepping mechanism comprises a limited pivoting Outer ring and an inner ring, which define an annulus, in the clamping elements, in particular clamping rollers are arranged. The outer ring is pivotable in both directions, wherein he by spring force with a torque towards one between two extreme positions lying neutral position is loaded. The Resetting the outer ring, with which typically a Swivel lever is rotatably connected, is in the neutral position accomplished by a spring element, which as to the outer ring wound torsion spring is formed, wherein the ends of the torsion spring engage in the annulus and doing one with the clamping elements interacting leading cage. Each clamping element is preferably effective in both directions of rotation, wherein the clamping element in neutral position of the outer ring in the middle in a double clamping ramp is arranged. The clamping ramp contour is preferably on the inner surface formed of the machined metal outer ring, while the inner ring has a continuous cylindrical outer surface having. The inner ring is particularly efficient as a non-cutting reshaped Sheet metal part can be produced and can be integrated with the inside directed entrainment elements, for example for a Switch cage, be formed.
In bevorzugter Ausgestaltung sind im Käfig zusätzlich zu den Klemmelementen Wälzkörper geführt, welche der radialen Lagerung des Innenrings relativ zum Außenring dienen. Die Wälzkörper sind ebenso wie die Klemmelemente vorzugsweise als Rollen ausgebildet und werden in diesem Fall als Stützrollen bezeichnet. Jedes Klemmelement ist vorzugsweise in einer gesonderten Tasche des Käfigs geführt und wird dabei derart durch die Kraft zweier in entgegengesetzte Richtungen wirkender Zentrierfedern beaufschlagt, dass sich das Klemmelement in der Neutralstellung des Außenrings exakt mittig in der Klemmrampenkontur befindet, wobei das Klemmelement von demjenigen Ring, der keine Rampenkontur aufweist, insbesondere vom Innenring, abgehoben ist.In preferred embodiment are in addition in the cage guided to the clamping elements rolling elements, which of the radial bearing of the inner ring relative to the outer ring serve. The rolling elements are just like the clamping elements preferably formed as rollers and are in this case as support rollers designated. Each clamping element is preferably in a separate Pocket of the cage and is doing so by the power of two persons acting in opposite directions Centering biased that the clamping element in the neutral position of the outer ring is located exactly in the center of the clamping ramp contour, wherein the clamping member of the ring, the no ramp contour has, in particular from the inner ring, lifted off.
Der Schwenkwinkel des Außenrings ist bevorzugt dadurch indirekt begrenzt, dass die sich beim Verschwenken zuziehende Drehfeder einerseits an einem gehäusefesten Anschlag anliegt und andererseits, mit ihrem zweiten Federende, durch den zusammen mit dem Außenring verschwenkten Käfig mitgenommen wird. Der gehäusefeste Anschlag, an welchem in Neutralstellung des Außenrings beide Federenden anliegen, ist vorzugsweise als Anschlagzunge ausgebildet, welche radial zwischen den Windungen der Feder und dem Außenring angeordnet ist. Die Drehbeweglichkeit des Käfigs relativ zu den einzelnen Federenden ist bevorzugt dadurch begrenzt, dass jedes Federende in eine schlitzförmige, sich in Umfangsrichtung erstreckende Ausnehmung des Käfigs eingreift.Of the Pivoting angle of the outer ring is preferably characterized indirectly limited that the torsion spring to be tightened during pivoting on the one hand rests against a housing-fixed stop and on the other hand, with its second spring end, through which together with the outer ring pivoted cage is taken. The housing fixed Stop at which in neutral position of the outer ring abut both spring ends, is preferably designed as a stop tongue, which radially between the turns of the spring and the outer ring is arranged. The rotational mobility of the cage relative to the individual spring ends is preferably limited by the fact that each Spring end in a slot-shaped, in the circumferential direction extending recess of the cage engages.
