fig1 is a side view of a bullet proof jacket with a mounting assembly formed in accordance with an embodiment . the mounting assembly includes a back plate 1 mounted by molle straps 2 to a body armour jacket 3 . the jacket 3 has horizontal webbing straps 4 which extend around the jacket 3 . the webbing straps 4 are fastened to the jacket 3 at aligned intervals , forming aligned points or gaps at which the molle straps 2 may be fed vertically through the webbing straps 4 between each strap and the jacket 3 . referring now to fig2 , the molle straps 2 are attached to the back plate 1 at the top and bottom by press studs 5 . the press studs 5 enable the user to easily detach the top and / or bottom of each molle strap 2 from the back plate 1 to release the back plate 1 and any equipment mounted thereon from the jacket 3 while wearing the jacket 3 . although press studs 5 are shown in fig2 , it is understood that other releasable fasteners for fastening the molle straps 2 to the back plate 1 may be used . referring now to both fig2 and fig3 , the back plate 1 has apertures 6 formed therein . the molle straps 2 may be weaved through the apertures 6 in order to fasten the back plate 1 to the jacket 3 . each molle strap 2 may be secured in place by a buckle 7 to facilitate quick attachment and removal of the back plate 1 from the jacket 3 if required or desired . with reference now back to fig1 and 2 , the back plate 1 also has a tank strap 10 that is mounted towards the top of the back plate 1 . in addition , the back plate 1 has an air supply valve mount 11 that is provided towards the bottom of the back plate 1 . the tank strap 10 and / or the valve mount 11 may have a quick release mechanism or operation . in an embodiment , the valve mount 11 includes a bayonet type coupling configured to interface with an air supply valve 12 to attach the air supply valve 12 to the back plate 1 . the bayonet type coupling may require a 90 degree turn of the air supply valve 12 in one direction relative to the back plate 1 to secure the air supply valve 12 to the back plate 1 , and a 90 degree turn in the opposite direction to release the air supply valve 12 from the plate 1 . the details of the bayonet type coupling are known in the art and will not be described in further detail herein . the valve mount 11 secures the air supply valve 12 to the back plate 1 . the valve mount 11 is configured to be located in a position on the back plate 1 that allows the air supply valve 12 coupled thereto to automatically locate or align with an air valve or outlet disposed on the top of an air tank ( not shown ) that is mounted onto the back plate 1 and secured in place with the tank strap 10 . the air supply valve 12 may include a fastener for coupling or sealing the air supply valve 12 to the air outlet of the air tank . the back plate 1 may also include pipe retainers 15 . the pipe retainers 15 are configured to route supply tubes or pipes from the air supply valve 12 to one or more designated operational positions , such as positions that are accessible to the user while the user is wearing the jacket . fig4 is a rear view of a mounting assembly according to another embodiment . fig5 is a rear view of a back plate which forms part of the mounting assembly of fig4 . in the embodiment of the mounting assembly shown in fig4 and 5 , like features are identified using the same reference numerals as the embodiment of the mounting assembly shown in fig1 - 3 . the mounting assembly in fig4 and 5 includes a back plate 20 that is configured in a similar manner to that of the back plate 1 shown in fig1 - 3 except that the shape has been changed to provide potentially a more comfortable fit for the wearer . the back plate 20 has apertures 6 arranged in two columns , with one column extending down each side edge of the back plate 20 . molle straps 2 may be woven through the apertures 6 ( or through the columns of apertures 6 ) in order to secure the back plate 20 to webbing straps of a carry jacket . each molle strap 2 may be secured to the back plate 20 at top and bottom ends by press studs 5 . the press studs 5 enable quick release of the molle straps 2 , such as when it is required to dump the back plate 20 and any apparatus mounted thereon . the back plate 1 , 20 ( according to either embodiment ) is configured to be used with a jacket having horizontally extending webbing straps distributed vertically down the jacket . each webbing strap may have portions that are not connected to the jacket , defining slots or gaps , which enables vertical straps to be threaded between the webbing straps and the jacket . the back plate 1 , 20 may be connected to the jacket by : threading a first connecting end of a molle strap 2 to the top press stud 5 on the respective plate 1 , 20 ; passing the molle strap 2 through one aperture 6 of one of the columns on the respective plate 1 , 20 : feeding the molle strap 2 between one of the webbing straps and the jacket ; feeding the molle strap 2 up through the next aperture 6 in the column and back down the subsequent aperture 6 in the column ; feeding the molle strap 2 between another of the webbing straps and the jacket ; and continuing on until the molle strap 2 has been fed through the last aperture 6 . once the molle strap 2 has been fed through the last aperture 6 , a second end is fastened to a lower press stud 5 . the process is repeated with a second molle strap 2 being fed through the apertures 6 of the second column . the back plates 1 , 20 thus may be secured to the jacket using the molle straps 2 . in an embodiment , after securing the back plate 1 , 20 to the jacket , an air supply valve 12 ( shown in fig2 ) may be secured to the valve mount 11 by engaging the coupling parts and turning the supply valve 12 through 90 degrees to lock the supply valve 12 to the valve mount 11 . supply pipes , configured to convey air to and / or from the user , may be fed through pipe retainers 15 to hold the supply pipes in place . finally , an air tank may be inserted through the tank strap 10 such that an air outlet of the air tank engages the supply valve 12 . the tank strap 10 is subsequently tightened to lock or secure the air tank to the back plate 1 , 20 . optionally , each of these steps may be performed by the user before donning the jacket or may be performed by a helper while the user is wearing the jacket . in an embodiment , the user has at least three options for removing equipment during use . first , the air tank may be removed by disconnecting the air outlet from the air supply valve 12 ( shown in fig2 ) and then releasing the tank strap 10 . the air tank may then be lifted off of the back plate 1 , 20 , leaving the back plate 1 , 20 , with the supply valve 12 coupled thereto , in place attached to the jacket . this option may be performed by the wearer on his or her own after first removing the jacket or may be performed with assistance from another person while the jacket is still being worn by the wearer . a second option is to remove both the air tank and the air supply valve 12 ( shown in fig2 ) together . the supply valve 12 is released by rotating the supply valve 12 a 90 degree turn relative to the valve mount 11 to disconnect it from the valve mount 11 . then , the tank strap 10 may be released to disconnect the air tank from the back plate 1 , 20 . the air tank with the supply valve 12 still attached may then be removed from the back plate 1 , 20 , leaving the plate 1 , 20 attached to the jacket . again , this second option may be performed by the wearer on his or her own by first removing the jacket or with assistance of another person while the jacket is still being worn by the wearer . this second option may be quicker than the first option and / or may relieve more weight than the first option . in an emergency situation , a third option for the user is to dump or remove the back plate 1 , 20 from the jacket while the air tank and air supply valve 12 ( shown in fig2 ) are both still attached to the back plate 1 , 20 so as to completely remove all of the equipment from the jacket . this option may be performed by the wearer without removing the jacket and without third party assistance by simply reaching behind and releasing the press studs 5 at either the top or the bottom of each molle strap 2 . once the molle straps 2 are released , the weight of the air tank causes the molle straps 2 to pull out of the apertures 6 and webbing straps , dropping the back plate 1 , 20 off of the jacket . it is to be understood that the above description is intended to be illustrative , and not restrictive . for example , the above - described embodiments ( and / or aspects thereof ) may be used in combination with each other . in addition , many modifications may be made to adapt a particular situation or material to the teachings of the invention without
