Embodiment Construction

[0019] To aid understanding, this document is organized as follows. First, refer to figure 1 A brief introduction depicts an exemplary use case of a polarization deceleration module (PDM). Second, refer to Figure 2A and Figure 2B , the discussion turns to an exemplary embodiment illustrating the operation of the PDM. specifically, Figure 2A shows movement with resistance in the retracted mode, while Figure 2B Free movement in extraction mode is shown. Next, refer to Figure 3A and Figure 3B , presents an exemplary PDM applied to a self-retracting device (SRD). Next, refer to Figure 4 and Figure 5 , the discussion turns to exemplary friction locations. Next, Figure 6A to Figure 6F Various exemplary surface shapes implemented on various exemplary shuttles are presented. Next, Figure 7A to Figure 7F Exemplary dynamic braking members (DBMs) having various shapes are presented. Next, refer to Figure 8A and Figure 8B , a further discussion of an exemplary...

Abstract

An apparatus and associated method involves a directional polarization deceleration module (PDM) including a shuttle (125) fixedly coupled to a spring biased spool (120) that can Rotationally coupled to the module housing (115), a dynamic braking member (DBM) (130), and a shuttle (125) configured to travel within a channel anchored to the module housing (115). A tether may be anchored to spool (120) on the proximal end. The DBM (130) may be pushed by the angled distal end of the shuttle (125) when the tether is retracted. The DBM (130) may be forced between the angled distal end of the shuttle (125) and the inner channel wall, thereby providing resistance to movement of the tether. When the tether is withdrawn, the DBM (130) can be pushed substantially perpendicular to the proximal end of the shuttle (125), thereby providing minimal resistance to motion for the tether. Various PDMs can decelerate the safety lanyard in one direction to substantially avoid entanglement and / or damage.

Description

technical field [0001] Various embodiments relate generally to personal protective equipment (PPE), and more specifically to safety lanyards and self-retracting devices (SRDs). Background technique [0002] All over the world, everyone is engaged in various jobs in order to survive. Many jobs involve hazards ranging from minor cuts and abrasions to more serious hazards such as loss of life. In some examples, highway construction workers may miss a speeding car. Welders may be exposed to intense light that may cause eye damage. Construction workers can be hit by falling objects. In some instances, trash and recycling collectors may be exposed to abrasive, sharp or corrosive waste. [0003] In hazardous environments, workers may wear personal protective equipment (PPE). PPE protects workers from the harmful effects of various hazards. For example, highway construction workers could wear brightly colored vests to make them highly visible to motorists. Welders may wear fa...
