Abstract
A valve for inflation and deflation of an air bag that is operable to allow air pressure to open the valve to allow air to enter the air bag with subsequent sealing of the valve upon removal of the air pressure source. For deflation, a common coin is insertable into the valve insert which is subsequently turned into a locked-open position, allowing egress of the air within the air bag.
