U.S. Pat. No. 3,841,328:  Airplane Hijacking Injector.

 hijackinjector1

Having described my invention, I claim:

1. Injector apparatus comprising, a general frame; a rigid sheet having an opening extending therethrough; means to secure said rigid sheet to said frame; a door; means to moveably secure said door to said rigid sheet; a resilient cushion supported by said rigid sheet; link means pivotally secured relative to the frame; bumper means on said link means to move said door relative to said rigid sheet; a hypodermic syringe having a plunger slidably disposed therein; a hollow needle attached to said hypodermic syringe, said plunger being arranged to force fluid through said hollow needle; means securing the syringe to said link means; means to pivot the link means relative to the frame such that the bumper engages the door and the needle is urged through the resilient cushion; and means to move the plunger to eject fluid through the hollow needle.

2. The combination called for in claim 1 wherein the link means comprising first and second links of substantially equal lengths arranged to form a parallel linkage such that upon movement of said links the needle on the syringe is maintained in a substantially vertical orientation.

3. The combination called for in claim 1 wherein the means securing the syringe to the link means comprises, a tubular body pivotally secured to the link means, said tubular body having a bore formed therein in which the syringe is disposed; and wherein the means to move the plunger comprises means secured to the tubular body and to the plunger of the syringe.

4. In combination with a seat, hypodermic injector means arranged to inject fluid into a person occupying the seat; means securing the hypodermic injector means relative to the seat; actuated means associated with the hypodermic injector means adapted to dispense fluid from the injector means; actuating means located remotely from the injector means, said actuating means being adapted to actuate the actuated means to inject fluid; an inflatable bag secured to the seat; a source of pressurized fluid; and means actuated by the actuating means to deliver fluid from said source to the bag.

5. In combination with a seat; hypodermic injector means arranged to inject fluid into a person occupying the seat; means securing the hypodermic injector means relative to the seat; actuated means associated with the hypodermic injector means adapted to dispense fluid from the injector means; actuating means located remotely from the injector means, said actuating means being adapted to actuate the actuated means to inject fluid; a seat belt having sections secured to said seat; a buckle arranged to connect said sections; and means actuated by said actuating means to lock said buckle to prevent disconnecting of said sections.

6. Injector apparatus comprising, a general frame; a cushion supported by said frame; link means pivotally secured relative to the frame; a hypodermic syringe having a plunger slidably disposed therein; a hollow needle attached to said hypodermic syringe, said plunger being arranged to force fluid through said hollow needle; resilient means initially mounted in compression associated with the syringe arranged to urge the plunger through the syringe; a tubular body pivotally secured to the link means, said tubular body having a bore formed therein in which the syringe is disposed; means to pivot the link means relative to the frame such that the needle is urged through the cushion; solenoid means having a moveable core; means to secure said solenoid means to said tubular body; and means detachably securing the plunger to the core such that the plunger is disengaged permitting movement thereof by the resilient means when the solenoid is energized.

7. Injector apparatus comprising, a general frame; a cushion supported by said frame; link means pivotally secured relative to the frame; a hypodermic syringe; a hollow needle secured to said syringe; a plunger slidably disposed in said syringe, said plunger being arranged to force fluid through said hollow needle; a tubular body pivotally secured to the link means, said tubular body having a bore formed therein; a hollow sleeve slidably disposed in the bore of the tubular body, said syringe being slidably disposed in the hollow portion of the sleeve; resilient means associated with the syringe arranged to move plunger through the syringe; means on said sleeve arranged to detachably secure the plunger to the sleeve; means to pivot the link means relative to the frame such that the needle is urged through the cushion; means secured to the tubular body arranged to move the sleeve through the bore in the tubular body until movement thereof is restricted at which time the plunger is disconnected from the sleeve permitting movement of the plunger by the resilient means for discharging fluid from the needle.

8. The combination called for in claim 7 wherein the means to detachably secure the plunger relative to the sleeve comprises solenoid means having a movable core; and hook means pivotally secured to the sleeve and engaging the plunger such that movement of the core against the hook means moves the sleeve until movement is restrained causing the hook means to pivot out of engagement with the plunger.
