<p>A tethering apparatus (14) including a harness (15), an anchor (16) and a line member (17) wherein said line member (17) connects said harness (15) to said anchor (16), further including a spool (19) about which the line member (17) is wound, said spool (19) having an inertia lock (18) for arresting the spool (19) when the line member (17) is unwound from the spool (19) at a rate above a predetermined value. The inertia lock (18) preferably includes a housing having an inner surface in the form of a ratchet (32), and a pawl (37) mounted for rotation about an axis substantially parallel to and offset from the axis about which the spool (19) rotates and wherein said pawl (37) is biased to a disengaged condition where the pawl (37) is disengaged from the ratchet (32) and wherein said pawl (37) engages the ratchet (32) and arrests the spool (19) when the line member (17) is unwound from the spool (19) at a rate above a predetermined value.</p> |
