Retractor with both emergency and automatic locking mechanisms |
摘要 |
A retractor with both emergency and automatic locking mechanisms is provided. The retractor has take-up spindle means; a ratchet wheel; a pawl member engageable with the ratchet wheel and displaceable between a first position, where the pawl member prevents any further rotation of the take-up spindle means in the webbing-releasing direction, and a second position where the pawl member is maintained out of engagement with the ratchet wheel, said pawl member normally assuming the second position; control means for bringing the pawl member to the first position when the webbing is wound on the take-up spindle means after release of the webbing over at least a predetermined first length from the take-up spindle means and then to the second position when the webbing has been taken up over at least a predetermined second length; and an emergency locking mechanism for sensing an emergency state to prevent any further rotation of the take-up spindle means in the webbing-releasing direction.
