An adjuster adjusts a length of at least one strap of a safety harness. The at least one strap is selected from the group consisting of at least one shoulder strap, at least one chest strap, at least one waist strap, at least one seat strap, and at least one leg strap. The adjuster comprises a base, a shaft rotatably operatively connected to the shaft and defining a slot configured and arranged to receive the at least one strap, and a locking mechanism interconnecting the base and the shaft. The locking mechanism allows rotation of the shaft in a first direction and prevents rotation of the shaft in a second opposite direction. |

1. An adjustment system for adjusting a length of at least one strap of a fall protection safety harness, the adjustment system comprising:
the fall protection safety harness configured to arrest a user wearing said safety harness during a fall, the safety harness including the at least one strap being selected from the group consisting of: at least one shoulder strap, at least one chest strap, at least one waist strap, at least one seat strap, and at least one leg strap; and an adjuster including: a base; a shaft rotatably operatively connected to the base, the shaft defining a slot configured and arranged to receive the at least one strap of the safety harness to adjust the length of the at least one strap while the user is wearing the safety harness; a locking mechanism interconnecting the base and the shaft, the locking mechanism being capable of moving between an engaged position and a disengaged position, the locking mechanism including a knob operatively connected to an end of the shaft, the knob and the shaft configured to rotate in a first direction and an opposite second direction, a spring operatively connected to the end of the shaft and to the knob to bias the knob toward the base into the engaged position, one of the base and the knob having at least one inclined ramp and the other of the base and the knob having at least one notch, wherein the at least one notch receives the at least one inclined ramp when in the engaged position, and wherein the shaft is rotatable relative to the base in the first direction while prevented from rotation in the second direction when the at least one ramp is positioned in the at least one notch in the engaged position, and wherein the shaft is rotatable relative to the base in the first and second directions when the locking mechanism in the disengaged position, wherein the locking mechanism is in the disengaged position when the at least one ramp is removed from the at least one notch as a direct result of the knob having been pulled axially away from the base and against the bias of the spring. |
