Self aligning window regulator

Abstract

A self-aligning window regulator for raising and lowering a windowpane in a motor vehicle door, having a mounting assembly fixed to the door comprising at least a mounting bracket, and a self-aligning assembly slidably attached to the mounting assembly at the mounting bracket. In certain preferred embodiments the self-aligning assembly includes a rail, a glider slidable over the rail, and attachment for connecting the glider to the windowpane. Connection element positioned between the rail and the mounting bracket allows the rail and the rest of the self-aligning assembly to float relative the mounting bracket. Preferably the connection element comprises a rivet extending from either the mounting bracket or the rail into a slot. The rivet can slide relative the slot and allow the self-aligning assembly to move relative the mounting bracket to accommodate stack-up tolerances or misalignments of the regulator componentry. To reduce potential rattle between the rivet and the slot, an elastomeric grommet may be positioned around the rivet. To reduce potential rattle between the mounting bracket and the rail, biasing members such as cup washers may be used, urging these components of the window regulator out of contact with one another.
