The invention relates to a structural element () of a motor vehicle, in particular of a motor vehicle seat, wherein the structural element () comprises a first component () and a second component (). In an overlap region (), the first component () and the second component () have a formed-closed connection, or a form-closed and form-closed connection, wherein the connection in the overlap region () can be produced by an electromagnetic pulse shaping method, wherein the first component comprises at least one form-closed molding (), wherein the second component can be molded into the at least one form-closed molding ().

Structural element for a motor vehicle

The invention relates to a fitting () for the seat of a vehicle, particularly a motor vehicle, comprising a first fitting part (), a second fitting part () which is mechanically linked to the first fitting part (), a locking eccentric, and a running eccentric (), wherein the running eccentric () is mounted in relation to the first fitting part () and second fitting part () by way of a rolling bearing or sliding bearing bushing (), wherein friction between the running eccentric () and the sliding bearing bushings () or between at least one sliding bearing bushing () and the associated fitting part () is lower than the friction between the locking eccentric and at least one of the fitting parts ().

Fitting for a vehicle seat

In a lever drive () for a vehicle seat adjuster, in particular in a motor vehicle seat, having a drive lever () which can be manually moved, at least one driven lever () operatively connected to the adjuster, and at least one transmission means (), which transmits a torque acting on the drive lever () to the driven lever () with a transmission ratio, the transmission ratio changes as a function of the transmitted torque.

Lever drive for a vehicle seat adjuster

A manual lever drive for an adjusting device on a seat for converting a lifting movement into a discontinuous rotational movement has a support arm and a step-by step mechanism having an output member and an input member. The output member is configured to be coupled with a rotatingly moveable control member of the adjusting device. A transmission member is connected to the input member for torque transmission onto the input member. A manual lever is connected to the support arm so as to pivot about a first axis of rotation. The manual lever is configured to actuate the transmission member. The transmission member is arranged on the input member providing a second axis of rotation. A pivot angle of the manual lever imparts to the transmission member a pivot movement increasing a corresponding pivot angle of the second axis of rotation.

Manual lever drive for adjusting devices on seats, in particular, motor vehicles seats

The articulated fitting has a stationary articulated part associated with the seat part and a swivelable articulated part associated with the backrest. These articulated parts are connected with one another via an adjusting shaft. An adjusting and locking device which is constructed as a gear unit and determines the position of the two articulated parts relative to one another is provided. The adjusting shaft has an eccentric portion for supporting one articulated part, this eccentric portion being formed by two wedge segments which are inclined relative to one another and engage regions of a driver of the adjusting shaft, by a driver arm engaging between the narrow sides of the wedge segments, and by a torsion spring which spreads apart the broad sides of the wedge segments with its spring legs. Therefore, the invention minimizes the play occurring between the driver arm and wedge segments as a result of operation and manufacture.

Articulated fitting for seats with adjustable backrest in particular for

Articulated fitting for seats having an adjustable backrest, in particular motor vehicle seats. The articulated fitting has an articulated part which is stationary with respect to the seat part and a swivelable articulated part associated with the backrest, these articulated parts being connected with one another via a swivel axle. The position of the two articulated parts relative to one another is determined by an adjusting and fixing device constructed as a gear unit. The swivel axle has an eccentric portion which is formed by two wedge segments which embrace a driver of the swivel axle, by a driver arm engaging between the narrow sides of the wedge segments, by an energy accumulator which presses apart the wide sides of the wedge segments and possibly by a centering segment arranged adjacent to the latter. The swivel axle has a central receptacle serving to connect with a transmission rod so as to be fixed with respect to rotation relative thereto. In order to achieve a reduction in structural component parts and an angular movability between the swivel axles of the articulated fittings on both sides and the transmission rod so as to compensate for alignment defects, the driver is constructed as a bushing which is connected with the driver arm integrated in the driver and with a cover disk covering the outer side of the articulated region and has a torque-transmitting receptacle for the transmission rod, this receptacle being constructed as a conical bore hole.

Articulated fitting for seats with adjustable backrest, in particular

Articulated fitting for seats having an adjustable backrest, in particular motor vehicle seats. The articulated fitting arranged on each longitudinal side of a seat has a stationary articulated part associated with the seat part and a swivelable articulated part associated with the backrest, these articulated parts being connected with one another via a swivel axle. The position of the two articulated parts relative to one another is determined by an adjusting and fixing device constructed as a gear unit. The swivel axle has an eccentric portion for supporting one articulated part and the swivel axle of each articulated fitting has a central receptacle serving to connect with a transmission rod so as to be fixed with respect to rotation relative thereto, which transmission rod couples the two articulated fittings of a seat with one another. In order to eliminate faulty assembly by means of determining visually whether or not the angular positions of the articulated parts of the two articulated fittings conform to one another, these articulated parts being connectable with the backrest, the transmission rod and the recess of the swivel axle which receives the transmission rod so as to be fixed with respect to rotation relative thereto have a profile cross section in the shape of a polygonal or toothed circumference having a missing corner or tooth, as the case may be, at a location on the circumference, this location being reduced to the core cross section of the transmission rod so that the transmission rod may be inserted into the recess of the swivel axle after a complete revolution of 360 degrees.

The connection of structural component parts in adjusting devices for seats, in particular for motor vehicle seats, is disclosed. In connecting structural component parts for adjusting devices for seats, the structural component parts to be rigidly connected with one another are welded in their connecting region. In order to prevent distortion of these structural component parts caused by the welding process, one structural component part has at least one bevel which projects toward the connection side and can be pressed into at least one recess of the other structural component part during a capacitor impulse welding process, this recess substantially conforming to the bevel with respect to shape and dimensions.

Connection of structural component parts in adjusting devices for seats,

A hinge joint which can be installed, for example, between the body supporting portion and the back rest of the seat in a motor vehicle has a first leaf affixed to the body supporting portion, a second leaf affixed to the back rest and a horizontal pintle which pivotally connects the second leaf to the first leaf. The actuating mechanism for pivoting the second leaf comprises a pair of wedge-like sections which are biased apart to bear against the balls and/or needles of one or more antifriction bearings between the first leaf and the sections. The sections flank a motion transmitting member which is moved about the axis of the pintle in order to release the second leaf for angular movement relative to the first leaf. A centering element can be installed next to the sections between the first leaf and a sleeve of the second leaf, and the bearing or bearings can extend between such centering element and the first leaf.
