Tension limiting mechanisms for closure devices and methods therefor

A reel for use with a lacing system for tightening an article comprising:

• a housing having an interior region;
• a spool positioned within the interior region of the housing and rotatable relative thereto, the spool having an annular channel formed therein;
• a knob rotatable relative to the housing and operably coupled with the spool to cause the spool to rotate within the interior region of the housing;
• a tension member coupled with the spool so as to be tensioned by winding the tension member around the spool's annular channel upon rotation of the knob;
• a tension control mechanism that is configured to enable tensioning of the tension member by rotation of the knob until a tension threshold is achieved, after which further rotation of the knob does not cause further tensioning of the tension member;
• and
• an adjustment mechanism that is operably coupled with the tension control mechanism and that is adjustable by a user to adjust the tension threshold upon which further rotation of the knob does not cause further tensioning of the tension member.
