Abstract

Abstract A helmet removal device for removing a helmet from a head of a wearer without applying tensile forces on the neck of the wearer. The removal device includes a bladder disposed between the helmet and the top of the head with the bladder so constructed and arranged that upon inflation from a collapsed configuration to an expanded configuration, the bladder at least partially displaces the head from within the helmet. The removal device may also include an inserting tool for inserting the bladder between the helmet and head while the helmet is being worn.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 81 words
A device for removing a helmet from about the head of a wearer, the device comprising: a bladder adapted to be disposed between the helmet and the head of the wearer, the bladder being folded into a collapsed configuration and expandable by inflation to cause the bladder to apply a force on the head and the inside of the helmet in a direction to at least partially displace the head from within the helmet to facilitate the removal of the helmet.
Claim 2
Independent Claim 81 words
A device for removing a helmet from about the head of a wearer, the device comprising: a bladder adapted to be disposed between the helmet and the head of the wearer, the bladder being folded into a collapsed configuration and expandable by inflation to cause the bladder to apply a force on the head and the inside of the helmet in a direction to at least partially displace the head from within the helmet to facilitate the removal of the helmet.
Claim 3
Dependent Claim 20 words
The device of claim 1 further including means for releasably retaining the bladder in the folded configuration prior to inflation.
Claim 4
Independent Claim 91 words
A device for removing a helmet from about the head of a wearer, the device comprising: a bladder adapted to be disposed between the helmet and the head of the wearer, and expandable by inflation to cause said bladder to apply a force on the head in a direction to at least partially displace the head from within the helmet to facilitate the removal of the helmet; and means for inserting the bladder between the head and helmet and placing the bladder in a desired location between the helmet and head.
Claim 5
Independent Claim 91 words
A device for removing a helmet from about the head of a wearer, the device comprising: a bladder adapted to be disposed between the helmet and the head of the wearer, and expandable by inflation to cause said bladder to apply a force on the head in a direction to at least partially displace the head from within the helmet to facilitate the removal of the helmet; and means for inserting the bladder between the head and helmet and placing the bladder in a desired location between the helmet and head.
Claim 6
Dependent Claim 29 words
The device of claim 3 wherein said inserting means includes an elongated member and means for releasably retaining the bladder at a forward end portion of the elongated member.
Claim 7
Dependent Claim 36 words
The device of claim 3 wherein the bladder is arranged in a folded configuration and a retaining means retains the bladder in the folded configuration during the insertion of the bladder between the helmet and head.
Claim 8
Dependent Claim 29 words
The device of claim 3 wherein the inserting means includes means for preventing the entanglement of a forward end of the inserting means in the hair of the wearer.
Claim 9
Dependent Claim 50 words
The device of claim 3 wherein said inserting means includes, a slat member having a straightened rear portion and a curved forward portion, and retaining means contacting at least one of the bladder and slat member for releasably retaining the bladder generally adjacent the curved portion of the slat member.
Claim 10
Dependent Claim 25 words
The device of claim 3 wherein the bladder defines a chamber, the device including means in fluid communication with the chamber for inflating the bladder.
Claim 11
Dependent Claim 19 words
The device of claim 8 wherein the inflating means includes a tube member in fluid communication with the chamber.
Claim 12
Dependent Claim 26 words
The device of claim 8 wherein the inflating means includes a means in fluid communication with the chamber for supplying a pressurized fluid to the chamber.
Claim 13
Dependent Claim 28 words
The device of claim 9 wherein the inflating means includes means removably connected to the tube member for providing pressurized fluid to the chamber to inflate the bladder.
Claim 14
Independent Claim 70 words
A method for removing a helmet from about the head of a wearer comprising the steps of: after the helmet is placed about the head, inserting a bladder within the helmet at a location generally corresponding to the top of the wearer's head; and inflating the bladder, said inflating step including partially displacing the head from within the helmet and facilitating the removal of the head from within the helmet.
Claim 15
Independent Claim 70 words
A method for removing a helmet from about the head of a wearer comprising the steps of: after the helmet is placed about the head, inserting a bladder within the helmet at a location generally corresponding to the top of the wearer's head; and inflating the bladder, said inflating step including partially displacing the head from within the helmet and facilitating the removal of the head from within the helmet.
Claim 16
Dependent Claim 14 words
The method of claim 12 further including folding the bladder into a collapsed configuration.
Claim 17
Dependent Claim 150 words
A kit for removing a helmet from about the head of a wearer, comprising: means for at least partially displacing the head from within the helmet, the displacing means including a bladder defining an internal chamber, the chamber being expandable by inflation to cause said bladder to apply a force on the head in a direction to at least partially displace the head from within the helmet to facilitate the removal of the helmet, the displacing means including a tube member in fluid communication with said chamber; means for inserting the bladder between the head and helmet and placing the bladder in a desired location between the helmet and head; means for releasably retaining the bladder at one end of the inserting means when the bladder is disposed adjacent said one end; and means adapted to be selectively connected to the tube member for providing compressed gas to the chamber.
Claim 18
Dependent Claim 150 words
A kit for removing a helmet from about the head of a wearer, comprising: means for at least partially displacing the head from within the helmet, the displacing means including a bladder defining an internal chamber, the chamber being expandable by inflation to cause said bladder to apply a force on the head in a direction to at least partially displace the head from within the helmet to facilitate the removal of the helmet, the displacing means including a tube member in fluid communication with said chamber; means for inserting the bladder between the head and helmet and placing the bladder in a desired location between the helmet and head; means for releasably retaining the bladder at one end of the inserting means when the bladder is disposed adjacent said one end; and means adapted to be selectively connected to the tube member for providing compressed gas to the chamber.
Claim 19
Dependent Claim 94 words
A combination helmet and helmet removal device comprising: a helmet configured to generally fit about a head of a wearer; and a foldable bladder within the helmet at a location whereby the bladder is disposed between the helmet and the head when the helmet is worn about the head, the bladder being folded into a collapsed configuration, the bladder being expandable by inflation to cause said bladder to unfold and apply a force on the head to at least partially displace the head from within the helmet to facilitate the removal of the helmet.
Claim 20
Dependent Claim 94 words
A combination helmet and helmet removal device comprising: a helmet configured to generally fit about a head of a wearer; and a foldable bladder within the helmet at a location whereby the bladder is disposed between the helmet and the head when the helmet is worn about the head, the bladder being folded into a collapsed configuration, the bladder being expandable by inflation to cause said bladder to unfold and apply a force on the head to at least partially displace the head from within the helmet to facilitate the removal of the helmet.
Claim 21
Dependent Claim 20 words
The device of claim 15 further including means for releasably retaining the bladder in the folded configuration prior to inflation.
