Fall arrest lanyard
An improved fall arrest lanyard apparatus and method for decelerating and arresting a user from impacting the ground after a fall, along with an integrated, deployable etrier. After the fall sequence has ended, the user may orient himself in a comfortable position using the deployed etrier so as to prevent or relieve the effects of suspension trauma while the user awaits rescue.
1. A fall arrest system, comprising:
a harness for supporting a user after a fall;
a fall arrest lanyard comprising a first strap with a first connector secured to a proximal end of said first strap for connecting said fall arrest lanyard to said harness;
a second connector secured to a distal end of said first strap for connecting said fall arrest lanyard to a secure point capable of supporting said user, wherein said second connector comprises a second strap with a first terminal end secured to said distal end of said first strap and a second terminal end configured for attachment to said secure point;
a deployable etrier attached to said first strap at a first location spaced from said first connector, said etrier having at least one stirrup that is high enough when said etrier is deployed to allow said user to stand in said stirrup to relieve tension in a section of said first strap below said first location such that said user can disconnect said first connector from said harness after said fall, wherein said first terminal end of said second strap is secured to said distal end of said first strap by a sewn loop through which said distal end of said first strap is looped to allow said first strap to slide through said sewn loop to deploy said etrier during said fall wherein said deployable etrier is attached to said first strap in a manner such that tension applied to said first strap during said fall causes said etrier to be automatically deployed; wherein said deployable etrier is stored inside a first sheathing that breaks away during a deployment of said deployable etrier, said etrier is stored in a folded state with the first strap folded around and enclosing the etrier within the sheathing; further comprising a shock pack attached to said first strap at a second location between said etrier and said first connector; wherein said etrier deploys prior to deployment of said shock pack;
a rescue line comprising a third connector attached to a distal end of said rescue line for connecting said rescue line to an anchor point located above said first location, said rescue line configured to allow said user to escape in a controlled descent from a suspended position after a fall upon disconnecting said fall arrest lanyard from said harness, wherein said harness comprises a connection point for receiving said rescue line to support said user during said controlled descent.
2. The fall arrest system of claim 1 wherein said first connector comprises a first lobster style connection clamp and wherein said second terminal end comprises a second lobster style connection clamp.
3. The fall arrest system of claim 1 wherein said first connector comprises a first load bearing ring and wherein said second terminal end comprises a second load bearing ring.
4. The fall arrest system of claim 2 wherein said etrier comprises a length of nylon material which includes at least one sewn loop.
5. The fall arrest system of claim 1 wherein said secure point comprises a self-retracting life line.
