Abstract
A buckle assembly includes at least one socket to receive and retain at least one lug therein, and an emergency release arrangement. The emergency release arrangement is operable to release the at least one lug from the socket in response to a predetermined trigger signal. The assembly also includes a manually operable resetting arrangement that is operable to retain the lug(s) re-inserted into the socket(s), following the triggering of the emergency release arrangement.
Claims17
A buckle assembly comprising:
- a base plate having at least one socket to receive and retain at least one lug therein;
- a face plate translatable with respect to the base plate;
- an emergency release arrangement configured to release the at least one lug from the socket in response to a predetermined trigger signal by translating the face plate away from the base plate to transition the buckle assembly from a pre-triggered state to a triggered state;
- and
- a manually operable resetting arrangement configured to retain the at least one lug re-inserted into the at least one socket when the buckle assembly is in the triggered state, the resetting arrangement having a reset plate, the reset plate configured to rotate with respect to the base plate to cause the face plate to translate toward the base plate, thereby allowing the buckle assembly to retain the at least one lug within the at least one socket when in the triggered state.

- an emergency release arrangement configured to release the at least one lug from the socket in response to a predetermined trigger signal by translating the face plate away from the base plate to transition the buckle assembly from a pre-triggered state to a triggered state;
- a water sensor having a plurality of water sensing modules, the water sensor configured to send the trigger signal to the emergency release arrangement only when at least two of the water sensor modules indicates the detection of water;
- and
- a manually operable resetting arrangement configured to retain the at least one lug re-inserted into the at least one socket when the buckle assembly is in the triggered state, the resetting arrangement having a reset plate, the reset plate configured to rotate with respect to the base plate to cause the face plate to translate toward the base plate, thereby allowing the buckle assembly to retain the at least one lug within the at least one socket when in the triggered state.
