Abstract
A quick release restraint system comprising a restraint body that mates a harness fitting with a moveable lockpin. The lockpin is held in a closed position by a return member and can be moved to an open position when a sleeve and/or a ripcord is moved away from the lockpin. The sleeve surrounds the restraint body and mates with an internal lockpin body that may also be attached to the ripcord. The ripcord and/or sleeve engage the lockpin body in a single direction to generate a pulling force that counteracts a biasing force of the return member.
Claims20
A quick release restraint system comprising:
- a restraint body extending from an open end to a closed end, said restraint body defining a hollow interior, and said closed end defining a lockpin aperture extending from said hollow interior through said closed end;
- a harness fitting secured to said restraint body adjacent said open end;
- a lockpin body containing a lockpin, said lockpin body retained within said hollow interior and said lockpin extending from said hollow interior through said lockpin aperture;
- a return member retained between said harness fitting and a first end of said lockpin body, said return member exerting a biasing force on said lockpin body towards said closed end;
- and
- a sleeve surrounding said restraint body containing a sleeve pin that protrudes into the hollow interior adjacent a second end of said lockpin body opposite said first end;
- wherein said sleeve pin exerts a pulling force when said sleeve moves away from said closed end, and said lockpin body moves away from the closed end from a fully closed position to a fully open position when said pulling force exceeds said biasing force.
An attachment system comprising:
- a restraint body extending from an open end to a closed end, said restraint body defining a hollow interior, and said closed end defining a lockpin aperture extending from said hollow interior through said closed end;
- a harness fitting secured to said restraint body adjacent said open end;
- a lockpin body containing a lockpin, said lockpin body retained within said hollow interior and said lockpin extending from said hollow interior through said lockpin aperture;
- a return member retained between said harness fitting and a first end of said lockpin body, said return member exerting a biasing force on said lockpin body towards said closed end;
- and
- a ripcord engaging said lockpin body;
- wherein said ripcord exerts a pulling force when said ripcord moves away from said closed end, and said lockpin body moves away from the closed end to a fully open position when said pulling force exceeds said biasing force.
The attachment system of claim 14, wherein said lockpin aperture is at a first end of said ring groove and said lockpin extends through said lockpin aperture to engage said restraint body at a second end of said ring groove opposite said first end of said ring groove.
The attachment system of claim 16, wherein said restraint aperture fully penetrates said restraint body.
