Abstract
A height adjustment control is provided for a retractable window shade. The window shade includes a top beam and a bottom beam with the bottom beam suspended below the top beam by at least one cord. The bottom beam can be adjusted and positioned relative to the top beam by adjustment of a length of cord extending between the top beam and the bottom beam. The height adjustment control system of this invention acts on the portions of the cord which are not suspended between the top beam and the bottom beam. A retainer is provided to gather up portions of the cord which are not in use. A retractor exerts a force on the retainer to cause the retainer to automatically gather up this excess cord. A cord brake is provided to hold the cord from passing onto the retainer and hold the bottom beam at a desired position below the top beam.
