Method for producing a bearing assembly and fitting for a vehicle seat having a bearing assembly produced according to said method

摘要

A method for producing a bearing assembly for a vehicle seat, which has a first bearing element (12) and a second bearing element (16) which can be moved in a movement direction (r) relative thereto, wherein the first bearing element first receives the second bearing element, with a large, undefined play in a play direction (p) which is perpendicular to the movement direction, and the first bearing element and/or the second bearing element is later deformed in a plastic manner by pressurizing in a stamping direction (x) until the first bearing element and the second bearing element contact each other without play in the play direction. Before the plastic deformation, the first bearing element elastically deforms under reduction of play and the elastic deformation is reversed after the plastic deformation, so that a defined clearance fit occurs between the first bearing element and the second bearing element.

1. A method for producing a bearing assembly for a vehicle seat, said bearing assembly having a first bearing element and a second bearing element which is movable relative thereto in a direction of movement, the method comprising the steps of:
receiving initially, by the first bearing element, the second bearing element with a large, undefined clearance in a direction of clearance which is perpendicular to the direction of movement; subsequent to the step of receiving, plastically deforming one of the first bearing element and the second bearing element by the one of the first bearing element and the second bearing element being acted upon in a stamping direction, until the first bearing element and the second bearing element bear against one another without clearance in the direction of clearance; after the step of receiving and before the step of plastically deforming, elastically deforming the first bearing element with the reduction of clearance; and reversing the elastic deformation after the plastic deformation so that a defined clearance fit is produced between the first bearing element and the second bearing element.
