EMERGENCY LOCKING RETRACTOR

摘要

The present disclosure describes a dual mode emergency locking retractor (ELR) employing a mechanical strap acceleration sensing and locking mechanism in conjunction with an omni-directional housing acceleration sensing and strap locking system. The ELR utilizes a locking means responsive to the strap payout acceleration rate once a threshold rate of acceleration has been exceeded. The locking means terminates shaft rotation with a locking force which is proportional to the strap payout acceleration rate.
