A hook assembly for a wire type window regulator, comprising:
- a. a wire;
- and
- b. a hook body having:
- a normally cylindrical intermediate portion,
- two circular flange portions, one at each axial end of said intermediate portion, each of said flange portions having a diameter greater than the diameter of said intermediate portion and a planar end surface, and
- an axially positioned hole extending through said hook body, said wire being inserted through said hole,
- wherein said intermediate portion is crimped substantially evenly along it axial length to secure said hook body to said wire, said intermediate portion being substantially rectangular in cross section after being crimped and said flange portions remaining uncrimped.
A method of securing a hook body to a wire of a wire-type window regulator, the hook body having an intermediate portion, two flange portions at axially opposed ends of the intermediate portion and having planar end surfaces, and an axially positioned hole extending through the hook body, the method comprising the steps of:
- inserting the wire through the hole of the hook body;
- and
- crimping the intermediate portion of the hook body substantially evenly along its axial length to provide the intermediate portion with a substantially rectangular cross section and to secure the hook body to the wire while leaving the flange portions uncrimped
