Abstract

Claims (25)

1. A method of adjusting

a major length of at least one strap of a fall arresting safety harness with an adjuster when said safety harness is donned by a user, 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, the adjuster including a base, a shaft rotatably operatively connected to the base 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 having a ratchet formed between the base and a knob biased axially into an engagement with the base via a spring, the spring connecting the shaft and the knob and allowing for disengagement of said engagement, wherein said engagement allows rotation of the shaft in a first direction and prevents rotation of the shaft in a second opposite direction, the method of adjusting comprising:

positioning the adjuster to a desired location on the at least one strap by sliding the adjustor along the major length of the at least one strap of the safety harness while donned by the user, wherein the at least one strap passes through the slot of the shaft of the adjuster; and

rotating the knob in the first direction to turn the shaft of the adjuster in the first direction causing a winding of the at least one strap about the shaft after said positioning in the desired location in order to reduce slack formed between two ends of the at least one strap; and

pulling the knob axially away from the base and against a bias of the spring to disengage the engagement between the knob and the base in order to disengage the ratchet which unlocks the locking mechanism in order to be able to rotate the shaft in both of said directions; and

rotating the knob in the second direction to turn the shaft of the adjuster in the second direction causing an unwinding of the at least one strap about the shaft.

2. The method of claim 1 , wherein said positioning of the adjuster at the desired location along the at least one strap further comprises:

positioning the adjuster proximate an intermediate portion of the at least one strap, wherein the at least one strap has a first portion proximate one side of the adjuster and a second portion proximate an opposing side of the adjuster; and

wherein said rotating of the knob in the first direction winds the first and second potions of the at least one strap about the shaft.

3. The method of claim 1 , wherein said positioning of the adjuster at a desired location along the at least one strap further comprises:

positioning the adjuster proximate one of the two ends of the at least one strap; and

wherein said rotating of the knob in the first direction winds a portion of the at least one strap proximate said one of the two ends about the shaft.

4. The method of claim 1 , further comprising:

interconnecting the at least one strap and a second straps of the safety harness, wherein the at least one strap is operatively connected to the shaft, and the second strap is operatively connected to the base.

5. The method of claim 4 , wherein the adjuster includes a male portion and a female portion, the male portion including the shaft, the female portion being configured and arranged to releasably engage the male portion, the at least one strap being connected to the male portion and windable about the shaft, the second strap being connected to the female portion.

6. The method of claim 1 , wherein the at least one strap is the at least one chest strap.

7. The method of claim 6 , wherein the at least one chest strap includes a first portion and a second portion, the adjuster interconnecting the first and second portions.

8. The method of claim 7 , wherein the adjuster includes a male portion and a female portion, the male portion including the shaft, the female portion being configured and arranged to releasably engage the male portion, the first portion being connected to the male portion and windable about the shaft, the second portion being connected to the female portion, the first and second portions being disconnected by disconnecting the male portion from the female portion.

9. The method of claim 1 , wherein the at least one strap is the at least one shoulder strap.

10. The method of claim 1 , wherein the at least one strap is the at least one waist strap.

11. The method of claim 10 , wherein the at least one waist strap includes a first portion and a second portion, the adjuster interconnecting the first and second portions.

12. The method of claim 11 , wherein the adjuster includes a male portion and a female portion, the male portion including the shaft, the female portion being configured and arranged to releasably engage the male portion, the first portion being connected to the male portion and windable about the shaft, the second portion being connected to the female portion, the first and second portions being disconnected by disconnecting the male portion from the female portion.

13. The method of claim 1 , wherein the at least one strap is the at least one leg strap.

14. The method of claim 13 , wherein the at least one leg strap includes a first portion and a second portion, the adjuster interconnecting the first and second portions.

15. The method of claim 14 , wherein the adjuster includes a male portion and a female portion, the male portion including the shaft, the female portion being configured and arranged to releasably engage the male portion, the first portion being connected to the male portion and windable about the shaft, the second portion being connected to the female portion, the first and second portions being disconnected by disconnecting the male portion from the female portion.
