Fall protection device and adjustment mechanism therefor

An adjustment mechanism for adjusting a length of a line that is paid out from a fall protection device, comprising:

• (i) a central gear configured to rotate with a hub about a central rotation axis;
• (ii) at least one gear attached to a housing of the fall protection device and configured to interact with the central gear;
• (iii) a pivot having a track configured to interact with the at least one gear and pivot as the at least one gear rotates;
• and (iv) an arm configured to urge at least a portion of an engagement mechanism causing it to move into an engagement position, to thereby prevent further rotation of the hub and payout of the line from the fall protection device.

A fall protection device, comprising:

• a housing;
• a rotatable hub having a body and a central rotation axis around which the body rotates with respect to the housing;
• a line wrapped around the hub and configured to pay out from and retract into the housing, the line having a first end attached to the hub and a second end having a connector attached thereto and configured for attachment to a harness of a user;
• an engagement mechanism configured to prevent rotation of the hub and further payout of the line;
• and
• an adjustment mechanism configured to adjust a predetermined length of the line paid out from the housing between a maximum length and a minimum length, the adjustment mechanism comprising:
• (i) at least one gear attached to the housing;
• (ii) a pivot having a track configured to interact with the at least one gear and pivot as the at least one gear rotates;
• and (iii) an arm on the pivot configured to urge at least a portion of the engagement mechanism into an engagement position after the predetermined length of the line is paid out from the housing to thereby prevent further rotation of the hub and payout of the line from the fall protection device.
