Abstract
An inflation device for storing and releasing pressurized fluid includes a substantially donut shaped cylinder (2) containing the pressurized fluid. An activation system (4) includes a trigger mechanism (6) positioned within a cavity (8) formed by the donut shaped cylinder (2). The cylinder (2) includes at least one puncturing zone (3) in contact with the pressurized fluid, the puncturing zone (3) including a sealing element (33) seated on a valve member inside the puncturing zone (3), the sealing element (33) connected to a puncturing rod (31). When activated, the trigger mechanism (6) actuates the puncturing rod (31), driving the sealing element (33) off the valve member thereby allowing the pressurized fluid to flow out of the cylinder (2) past the sealing element (33) and through the puncturing zone (3).
Claims33
An inflation device including:
- a cylinder containing a pressurised fluid;
- an activation system including a trigger mechanism positioned within a cavity formed by the cylinder;
- at least one puncturing zone in contact with said pressurised fluid, the puncturing zone including a sealing means seated on a valve member, the scaling means connected to a puncturing rod a distal end of which is substantially adjacent said trigger mechanism;
- wherein, when activated, said trigger mechanism actuates said puncturing rod, driving said sealing means off said valve member, thereby allowing said pressurised fluid to flow out of said cylinder past said valve member and through said puncturing zone.
The inflation device of any one of the previous claims wherein said pressurised fluid is substantially air.
The inflation device of any one of the previous claims wherein said valve member is in fluid contact with an inflatable member.
A mechanical air bag device including;
- a cylinder;
- at least one puncturing zone on the surface of the cylinder;
- an activation system positioned within a cavity formed by the cylinder, and which is responsible to a pre-selected acceleration or deceleration;
- wherein the activation system includes a trigger mechanism which is adapted to stimulate a puncturing mechanism when the pre-selected acceleration or deceleration is detected or met, the puncturing mechanism, being adapted to release the cylinder's content via the puncturing zone.
A mechanical air bag inflation system including;
- a cylinder;
- at least one puncturing zone adjacent to the surface of the cylinder;
- an activation system including a trigger mechanism and a puncturing mechanism positioned within a cavity formed by the cylinder, and which is responsive to a pre-selected acceleration or deceleration;
- an air bag in fluid communication with the puncturing zone;
- wherein when the pre-selected acceleration or deceleration is selected or met, the trigger mechanism is activated to stimulate the puncturing mechanism which releases the content of the cylinder through the puncturing zone to substantially inflate said air bag.
A mechanical air bag inflation device including;
- a cylinder,
- at least one puncturing zone on the surface of the cylinder,
- an activation system which is responsive to a pre-selected acceleration or deceleration and wherein the activation system includes a puncturing rod which requires only one movement to puncture the puncturing 7,one and release the content of the cylinder.
An inflation device substantially as herein described and with reference to the accompanying drawings.
