A reel assembly for controlling the displacement of webbing comprising: a webbing shaft with a geared end plate, the webbing being wound about the webbing shaft; and a locking dog (48, 70) having first and second locking teeth (74, 76), each locking tooth (74, 76) configured to selectively lockingly engage a respective first and second engagement surface (80, 84, 86, 88) on the geared end plate to prevent displacement of the webbing upon rotation of the locking ring when the webbing shaft experiences a force having a predetermined magnitude, wherein, when the webbing shaft experiences the force having the predetermined magnitude, rotation of the webbing shaft is first partially arrested by the engagement of the first locking tooth of the locking dog (48, 70) with the first engagement surface (80, 86) on the geared end plate and subsequently completely arrested by the combined engagements of the first and second locking teeth (74, 76) with their respective first and second engagement surfaces (80, 84, 86, 88), wherein a gap is initially defined between the second locking tooth and the second engagement surface (84, 88) when the first locking tooth is engaged with the first engagement surface (80, 86), wherein the gap is subsequently closed by either: a) deflection of the first engagement surface (80, 86) until the second locking tooth engages the second engagement surface (84, 88), or b) deflection of the first locking tooth until the second locking tooth engages the second engagement surface (84, 88). a webbing shaft with a geared end plate, the webbing being wound about the webbing shaft; and a locking dog (48, 70) having first and second locking teeth (74, 76), each locking tooth (74, 76) configured to selectively lockingly engage a respective first and second engagement surface (80, 84, 86, 88) on the geared end plate to prevent displacement of the webbing upon rotation of the locking ring when the webbing shaft experiences a force having a predetermined magnitude, wherein, when the webbing shaft experiences the force having the predetermined magnitude, rotation of the webbing shaft is first partially arrested by the engagement of the first locking tooth of the locking dog (48, 70) with the first engagement surface (80, 86) on the geared end plate and subsequently completely arrested by the combined engagements of the first and second locking teeth (74, 76) with their respective first and second engagement surfaces (80, 84, 86, 88), wherein a gap is initially defined between the second locking tooth and the second engagement surface (84, 88) when the first locking tooth is engaged with the first engagement surface (80, 86), wherein the gap is subsequently closed by either: a) deflection of the first engagement surface (80, 86) until the second locking tooth engages the second engagement surface (84, 88), or b) deflection of the first locking tooth until the second locking tooth engages the second engagement surface (84, 88). a) deflection of the first engagement surface (80, 86) until the second locking tooth engages the second engagement surface (84, 88), or b) deflection of the first locking tooth until the second locking tooth engages the second engagement surface (84, 88).
