Emergency opening device for a closure
An integrated system for releasing trapped persons in a vehicle (PARIS) includes a central management unit (CPU) to which sensors (D 1 , D 2 , . . . Dn), an input-output socket (S) for connecting a service computer and control switches or buttons, and at least the following are connected at an output of the central management unit: an automatic seatbelt cutting system (SBC), a system for automatically opening door locks and bolts and locking them in the open position (LOB), and a system for automatically swinging doors and locking them in the open position (DOB).
1. A system for emergency opening of a movable closure ( 42 ) inserted in an immovable element ( 47 ) and which constitutes a barrier between two spaces, wherein the system comprises an actuator ( 1 ) able to move the closure ( 42 ) from a closed position into an open position, wherein the actuator ( 1 ) comprises:
a casing ( 88 ),
at least one sliding-out element ( 2 , 3 , 4 , 82 , 86 ), placed at least partially in the casing ( 88 ), and
at least one gas generator ( 11 , 12 ) able to drive the at least one sliding-out element ( 2 , 3 , 4 , 82 , 86 ) away from the casing, wherein the casing ( 88 ) is fixed in an opening in one of the immovable element ( 47 ) and the closure ( 42 ) and the at least one sliding-out element is fixed to the other one of the immovable element and the closure,
wherein the at least one gas generator ( 11 , 12 ) is placed in the casing ( 88 ) of the actuator ( 1 ), wherein the at least one gas generator ( 11 , 12 ) at least partially or in total enters the at least one sliding-out element ( 2 , 3 , 4 , 82 , 86 ), and
wherein the at least one sliding-out element is inflatable and made from a flexible material.
2. The system according to claim 1 , wherein the at least one gas generator ( 11 , 12 ) is mounted to a mounting head of the casing ( 88 ).
3. The system according to claim 1 , wherein a volume of the at least one sliding-out element ( 82 , 86 ) increases in response to the gas generated by the at least one gas generator ( 11 , 12 ).
4. The system according to claim 1 , wherein the gas generator comprises compressed gas.
5. A system for emergency opening of a movable closure ( 42 ) inserted in an immovable element ( 47 ) and which constitutes a barrier between two spaces wherein the system comprises an actuator ( 1 ) able to move the closure ( 42 ) from a closed position into an open position, wherein the actuator ( 1 ) comprises:
a casing ( 88 ),
at least one sliding-out element ( 2 , 3 , 4 , 82 , 86 ), placed at least partially in the casing ( 88 ), and
at least one gas generator ( 12 ) able to drive the at least one sliding-out element ( 2 , 3 , 4 , 82 , 86 ) away from the casing, wherein the casing ( 88 ) is fixed in an opening in the movable closure ( 42 ) and the at least one sliding-out element is fixed to the immovable element,
wherein the at least one gas generator ( 12 ) is placed in the casing ( 88 ) of the actuator ( 1 ) in parallel with an axis of operation of the actuator ( 1 ), wherein the at least one gas generator ( 12 ) at least partially or in total enters the at least one sliding-out element ( 2 , 3 , 4 , 82 , 86 ), and
wherein the at least one sliding-out element is inflatable and made from a flexible material.
