The tank 42 is connected to an upper inflation line 38. When the receiver 44 receives an inflation signal from a remote control 54, the receiver 44 controls the valve control unit 50 which is powered by a power source 51. Once activated, the valve control unit 50 controls the upper release valve 46 and the lower release valve 48 to open, thereby providing the compressed air in the tanks 42 to the upper and lower inflation lines 38 and 40, respectively. The compressed air travels through the upper inflation line 38 and lower inflation line 40 to inflate the inflatable chambers of the inflatable restraint 10.
FIG. 9 is a perspective view of the remote control unit 54 of the inflatable restraint of the present invention. The remote control unit 54 has a transmitter and antenna 62 for sending signals to the receiver 44 of the inflation unit 32. The remote control has an activation button 56 for instant activation of the inflation unit 32. Instant activation of the inflation unit 32 causes compressed air to be delivered to the neck chamber 16, right arm chamber 18, left arm chamber 20, and leg chamber 22 thereby filling these chambers and causing immediate immobilization of any person outfitted with the inflatable restraint 10. The level of air which is released into the inflatable members of the inflatable restraint 10 upon activation of the activation button 56 is predetermined and is based upon the body size of the individual wearing the restraint 10. The remote control unit 54 also includes a decrease pressure button 58 and an increase pressure button 60. The increase pressure button 60 signals the valve control unit 50 to open the upper release 46 and lower release valve 48. Activation of the increase pressure button 60 allows the person activating the inflatable restraint 10 the ability to apply more pressure and further subdue a person wearing the restraint 10. The decrease pressure button 58 functions to reduce the pressure in the inflatable members when the person 14 activating the inflatable restraint 10 deems appropriate. This reduction in pressure ensures that the inflatable restraint 10 remains a non-lethal method of immobilizing a detainee and allows the person wearing the restraint 10 additional mobility.
FIG. 10 is a block diagram showing communication between the remote control unit 54 and the receiver 44 of the inflatable restraint 10 of the present invention. Shown is the remote control unit 54 including a transmitter having a button to allow for transmission of an activation command and buttons to vary the extent of inflation needed for restraint of a detainee wearing the present invention. Activation of the control buttons connects the power source to the transmitter to transmit an inflation or deflation signal to the inflatable restraint 10. Upon receipt o the transmitted signal the received signal is provided to the valve control unit 50. The valve control unit 50 analyzes the signal and controls the upper and lower release valves 46 and 48 respectively, to inflate or deflate the chambers. Once activated, the valve control unit 50 signals the upper valve release 46 and the lower valve release 48 to release the compressed air in the tanks 42. The compressed air travels through the upper inflation line 38 and lower inflation line 40 to inflate the inflatable member of the inflatable restraint 10.

The left arm chamber 20 preferably receives the left arm of the detainee 12 and is positioned at the joint between the left arm and shoulder. The lower harness 26 of the inflatable restraint 10 is preferably maintained around the waist and legs of the detainee 12 by thigh straps 21 and is secured in position by a locking mechanism 31. The lower harness a leg chamber positioned between the legs of the detainee 12 and held in position by the thigh straps 21.
When immobilization is required, a person 14, preferably a law enforcement official, activates the remote control unit 54 which transmits a signal to the inflation unit 32. The signal is received by a receiver 44 connected to the inflation unit 32 and is provided to a valve control unit 50. The valve control unit 50 controls an upper and lower release valve 46, 48 to cause the air tanks 42 to release air into the neck chamber 16, the right arm chamber 18, the left arm chamber 20, and the leg chamber 22. As a result the detainee 12 is unable to move due to the inflated chambers surrounding his appendages. The inflatable chambers restrict movement sufficiently enough to prevent any resistance attempted by the detainee 12 and also adequately prevents attempted escape by the detainee.
FIG. 12 a perspective view of the inflatable restraint of the present invention in its inflated state. The inflatable restraint 10 is attached to a detainee by an upper harness 24 and a lower harness 26. The upper harness 24 and lower harness 26 are both connected to an inflation unit 32 by an upper support member 34 and a lower support member 36 as can be seen in FIGS. 3-5. The upper harness 24 is preferably maintained around the upper torso of the detainee 12 by shoulder straps 17 and is secured in position by a locking mechanism 30. The upper harness 24 is connected to a neck chamber 16 extending around a rear side of the neck of a detainee 12. The upper harness 24 is also connected to both a right arm chamber 18 and a left arm chamber 20. The right arm chamber 18 preferably receives the right arm of the detainee 12 and is positioned at the joint between the right arm and shoulder. The left arm chamber 20 preferably receives the left arm of the detainee 12 and is positioned at the joint between the left arm and shoulder. The lower harness 26 of the inflatable restraint 10 is preferably maintained around the waist and legs of the detainee 12 by thigh straps 21 and is secured in position by a locking mechanism 31. The lower harness a leg chamber positioned between the legs of the detainee 12 and held in position by the thigh straps 21.
FIG. 13 a detailed illustrative view of the inflatable restraint of the present invention in its inflated state. Shown herein is the position of a right arm of a detainee 12 when the inflatable restraint 10 is inflated. The right arm chamber 18 of the inflatable restraint 10 positioned around a right arm of a detainee and held in position by the upper harness 24. The upper harness 24 is connected to an inflation unit 32 by an upper support member 34. The upper harness 24 is positioned around the upper torso of the detainee 12 and held in place by shoulder straps 17. A locking mechanism 30 secures the upper harness in position. The upper harness 24 is connected to a neck chamber 16 extending around a rear side of the neck of a detainee 12. In this figure, the right arm of the detainee 12 is immobilized by the inflated right arm chamber 18. Further, the detainee's 12 head is immobilized by the inflated neck member 16. This figure shows the detainee is unable to move effectively and thereby, if required, completely immobile and subdued.
From the above description it can be seen that the inflatable restraint of the present invention is able to overcome the shortcomings of prior art restraint devices by providing a non-lethal way in which to immobilize a person by inflating members around the appendages that control a persons movements. Furthermore, the present invention is simple and easy to produce and use.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
