Inflator for inflating an air bag having magnetically coupled internal ignition
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).
Abstract(Chinese):

压力容器（12）包含用于使充气车辆乘员保护装置（11）充气的充气流体源。 压力容器（12）包括限定用于充气流体从压力容器（12）流入充气车辆乘员保护装置的通道（54）的表面（52）。 压力容器（12）内部的装置（68和/或96）发送或接收电信号。 能量传输装置（70）通过压力容器（12）的壁部分（24）将能量传递到压力容器（12）中或从压力容器（12）传出）。 能量传输装置（70）包括在压力容器（12）外部的第一部分（72）和压力容器（12）内的第二部分（74）。 能量传输装置（70）的第一和第二部分（72,74）中的一个将能量转换成电流。 能量传输装置（70）的第二部分（74）与压力容器（12）内部的装置电连接。 在一个实施例中，压力容器（12）内的装置是由电流致动以引起充气流体从压力容器（12）流动的爆管（68）。
