ABSTRACT:
A pressure vessel (12) contains a source of inflation fluid for inflating an inflatable vehicle occupant protection device (11). The pressure vessel (12) includes a surface (52) which defines a passage (54) for inflation fluid to flow from the pressure vessel (12) into the inflatable vehicle occupant protection device. A device (68 and/or 96) inside the pressure vessel (12) sends or receives electrical signals. An energy transmitting device (70) transmits energy into or out of the pressure vessel (12) through a wall portion (24) of the pressure vessel (12). The energy transmitting device (70) includes a first portion (72) outside the pressure vessel (12) and a second portion (74) inside the pressure vessel (12). One of the first and second portions (72, 74) of the energy transmitting device (70) converts the energy into electrical current. The second portion (74) of the energy transmitting device (70) is electrically connected with the device inside the pressure vessel (12). In one embodiment, the device inside the pressure vessel (12) is a squib (68) which is actuated by electrical current to cause inflation fluid to flow from the pressure vessel (12).
