Abstract

An occupant restraint system includes a plurality of occupant residences each including a restraint assembly having a latch mechanism manually movable between a latched state and an unlatched state and an electric lock mechanism movable from an unlocked state to a locked state when the latch mechanism is in the latched state. The control console includes an electronic display of the plurality of occupant residences and a user interface for actuating the electric lock mechanism between the locked state and the unlocked state. An occupancy tabulation system is constructed and arranged to send a signal to the control console indicative of occupied residences of the plurality of occupant residences for displaying an occupied condition associated with the occupied residences on the electronic display.

Claims

1. An occupant restraint system for a vehicle comprising:

a plurality of occupant residences disposed in the vehicle, and each including a restraint assembly having a latch mechanism manually movable between a latched state and an unlatched state and an electric lock mechanism movable from an unlocked state to a locked state when the latch mechanism is in the latched state;

a control console disposed in the vehicle, and including an electronic display of the plurality of occupant residences and a user interface for actuating the electric lock mechanism between the locked state and the unlocked state; and

an occupancy tabulation system located remotely from the vehicle, and constructed and arranged to send a signal to the control console indicative of occupied residences of the plurality of occupant residences for displaying an occupied condition associated with the occupied residences on the electronic display, wherein the electric lock mechanism is integrated into the latch mechanism, the electric lock mechanism is constructed and arranged not to lock when the latch mechanism is in the unlatched state, and the occupancy tabulation system includes a plurality of occupancy sensors with each occupancy sensor associated with a respective one of the plurality of occupant residences, and each occupancy sensor is constructed to initiate an occupied signal to the control console.

2. The occupant restraint system set forth in claim 1, wherein the occupancy tabulation system includes a bar code reader constructed and arranged to identify each occupant.

3. The occupant restraint system set forth in claim 2, wherein the occupancy tabulation system includes a data store that receives input from the bar code reader and a wireless connection for downloading the data store to the control console.

4. The occupant restraint system set forth in claim 1, wherein the electric lock mechanism includes an electromagnet.

5. The occupant restraint system set forth in claim 1, wherein the restraint assembly includes a flexible belt and a latchable buckle that includes the latch mechanism and the electric lock mechanism.

6. The occupant restraint system set forth in claim 5, wherein the plurality of occupant residences is a plurality of airplane seats.

7. The occupant restraint system set forth in claim 1, wherein the user interface includes an all-unlock selector for placing all of the electric lock mechanisms in the unlocked state.

8. The occupant restraint system set forth in claim 1, wherein the occupant restraint system is generally in a vehicle and the user interface includes a clear selector for clearing all data after travel completion.

9. The occupant restraint system set forth in claim 3, wherein the user interface includes a load data selector for loading data from the data store to the control console.

10. The occupant restraint system set forth in claim 1 comprising:

a processor for receiving and sending control signals from and to the control console and from and to the electric lock mechanism of each one of the plurality of occupant residences.

11. The occupant restraint system set forth in claim 10, wherein the processor includes a router having a plurality of ports with each port associated with the electric lock mechanism of a respective one of the plurality of occupant residences.

12. The occupant restraint system set forth in claim 3 comprising:

a processor for receiving and sending control signals from and to the control console, and wherein the processor includes a router having a plurality of ports with each port associated with the electric lock mechanism of a respective one of the plurality of seats and a respective one of the plurality of occupancy sensors.

13. A method of operating an occupant restraint system in a vehicle comprising the steps of:

identifying occupied seats disposed in the vehicle via an electrical occupancy tabulation system located remotely from the vehicle;

receiving seat occupancy data from the electrical occupancy tabulation system into a control console via a computer processor;

displaying the occupied seats on an electronic display of the control console;

notifying occupants to manually place a latch mechanism of a restraint assembly into a latched state;

remotely placing a lock mechanism of the restraint assemblies in the latched state into a locked state via a user interface of the control console;

displaying occupied seats that are not in the locked state on the electronic display of the control console; and

notifying the occupant in one of the occupied seats and with a lock mechanism not in the locked state to place the latch mechanism in a latched state, wherein the electrical occupancy tabulation system includes an occupancy sensor placed in each one of the plurality of seats.

14. The method set forth in claim 13 comprising the further step of:

operating a selector on the user interface to place all lock mechanisms in an unlocked state;

manually placing the latch mechanism into an unlatched state by the occupant; and

disembarking from the occupied seat by the occupant.

15. The method set forth in claim 13, wherein the electrical occupancy tabulation system includes a bar scanner that inputs data into a data store.
