DEFINITION

Classification: 242/382.1

Material responsive (e.g., automatic lock):

(under subclass 382) Subject matter in which the unwinding lock includes an actuator operated in response to the completion of a predetermined cycle of material unwinding, which cycle may be a set time period, a length of unwound material, change in direction of spool movement, termination of unwinding, or similar condition, but excludes actuation responsive to unwinding speed or acceleration, per se.

(1) Note. Typically these devices permit initial unwinding (e.g., for seatbelt placement) that completes the unwinding cycle and actuates the unwinding lock.
