WEAR-PROOF DÉTENTE FOR FOLDING MIRRORS

摘要

A folding assembly for a vehicle side mirror that employs specialized ramped détentes. The folding assembly includes a pivot tube and a pivot spring rotatably coupled to a case frame and rigidly coupled to a base frame. The base frame includes a series of ramped détentes that are seated within corresponding recesses in the case frame. The inside angle (beta1) of the ramps of the détentes is steeper than the outside angle (beta2) of the ramps of the détentes according to a predetermined formula so that when the case frame is rotated relative to the base frame, and the détentes move out of their recesses, the force of the rotation is distributed along the entire length of the ramp to increase the durability performance of the mirror and thus its longevity.
