Embodiment Construction

[0020] figure 1 A blocking and tilting adjustment device with latching pawls according to the invention is shown schematically. The fitting 1 is composed of a first fitting part 2 and a second fitting part 3 , which are rotatable relative to each other about an axis of rotation 4 . The second fitting part 3 is for example arranged on the seat part and the fitting part 2 is arranged on the backrest of the vehicle seat, or vice versa. The locking takes place by engaging the cooperating teeth 15 of the latch pawl 5 into the teeth 6 of the second fitting part 3 . The latch pawl 5 is arranged on the fitting part 2 so as to be rotatable about the axis 7 and is clamped in the tooth 6 by the blocking cam 8 and is fixed in this position. A blocking cam 8 resting on the periphery of the latch pawl 5 rotates relative to the fitting part 2 about an axis of rotation 9 and meshes via partial peripheral teeth 10 with a pinion 11 having a direction along the latch pawl 5 . The directionall...

Abstract

The invention relates to a method for producing components of an adjustment device for a vehicle seat, wherein in a first step the workpiece is machined such that it is harder in the first region than in the second region and / or such that it is harder in the third region. The region has a larger geometry than in the fourth region, wherein in the second step the workpiece is deformed by moving the tool over the workpiece at a speed greater than 1 m / s.

Description

technical field [0001] The invention relates to a method for producing a part of an adjustment device for a vehicle seat, wherein in a first step the workpiece is machined in such a way that it is harder in the first region than in the second region and / or in such a way that it is harder in the third region. The zone has a larger geometry than the fourth zone, wherein in a second step the workpiece is shaped by moving the tool over the workpiece at a speed greater than 1 m / s. Background technique [0002] Methods of producing components are well known. Furthermore, documents EP 1 516 717 A1, WO 2007 / 026091 A1 and WO 2007 / 026090 A1 disclose methods and devices using the principle of adiabatic separation. In the principle of adiabatic separation, the tool is moved at high speed over the workpiece so that the part is punched out as heat develops at the separating edge. A disadvantage of the known methods and devices is that, after the stamping operation, further processing, e...
