Tensioner for window regulator

A window regulator, comprising:

• a first guide rail;
• a first cursor slidably mounted to the first guide rail;
• a second guide rail spaced from the first guide rail;
• a second cursor slidably mounted to the second guide rail;
• a housing;
• a motor mounted to the housing and operably coupled to the cursor such that operation of the motor will cause the first cursor to slide along the first guide rail and the second cursor to slide along the second guide rail;
• a cable drum rotationally mounted to the housing;
• the cable drum being operably coupled to the motor;
• a first cable secured to the cable drum at one end and the first cursor at another end;
• a second cable secured to the cable drum at one end and the second cursor at another end;
• a third cable secured to the first cursor at one end and the second cursor at another end;
• a first cable sheath surrounding the first cable, a first end of the first cable sheath extends from a first feature of the first guide rail;
• a short drop tensioner located between the housing and a second end of the second cable sheath, the short drop tensioner consisting only of three parts:
• a tensioner support, a tensioner sleeve, and a spring disposed between the tensioner support and the tensioner sleeve;
• a second cable sheath surrounding the second cable that extends from the housing to a second feature of the second guide rail;
• and
• a third cable sheath surrounding the third cable that extends from a second feature of the first guide rail to a first feature of the second guide rail, wherein the window regulator is configured for raising and lowering a window of a frameless door assembly of a sleeve;
• each of the three parts, respectively, forms a single monolithic construction.

A method of taking up slack in a first cable of a window regulator, comprising:

• slidably mounting a cursor to a guide rail;
• a motor mounted to a housing and operably coupled to the cursor such that operation of the motor will cause the cursor to slide along the guide rail;
• rotatably mounting a cable drum to the housing, the cable drum being operably coupled to the motor;
• securing a first cable to the cable drum at one end and the cursor at another end;
• securing a second cable to the cable drum at one end and the cursor at another end;
• surrounding the first cable with a first cable sheath, a first end of the first cable sheath extends from a first feature of the guide rail;
• surrounding the second cable with a second cable sheath, the second cable sheath extending from the housing to a second feature of the guide rail;
• locating a cable tensioner between the housing and a second end of the second cable sheath, the cable tensioner consisting only of three parts:
• a tensioner support, a tensioner sleeve, and a spring disposed between the tensioner support and the tensioner sleeve;
• and
• wherein the window regulator is configured for raising and lowering a window of a frameless door assembly of a sleeve;
• each of the three parts, respectively, forms a single monolithic construction.
