  • Patent number: 5497578
    Abstract: A cross-arm window regulator for moving a window between raised, intermediate and lowered positions in a vehicle door, includes a resilient stop cushion housed in the lift channel mounted on the glass. Sliders mounted on the ends of the lift and cross arms engage the ends of the cushion as the window nears raised position, gradually compressing it to cushion window movement to raised position. If the geometry is the same for raised and lowered positions, the same cushioning will also occur in the window lowered position. The spring rate increases as compression occurs. The cushion can be a foam butyl rubber strip or a metal spring of various types. The spring rate can be tailored by making the cushion a dual density foam strip, a foam strip with holes of varying sizes to provide a variable cross-section, or a coated foam strip. An integral stop can be included in the form of a hard plastic shell for the foam strip or spring.
