摘要： A detector for sensing a leaking of fluid pressures. The detector is characterized by an hermetically sealed housing confining therewithin a first or normalized pressure, a connector for coupling the housing in direct communication with a suspected leak established within a substantially sealed body, an electrical circuit having a first or normalized configuration and including a pair of circuit-completing electrical contacts and means mounting at least one contact of said pair of contacts on a flexible wall of the housing supporting the contact for movement from a first position along a linear path to a second position in response to an altering of the pressure confined within the housing for thereby altering the configuration of the circuit.

摘要： A pressure sensing means responsive to gas pressure within a gas containing vessel of a motor vehicle''s inflatable bag restraint system is connected in parallel with a signal means located within the passenger compartment of the vehicle. The connection is such that the signal means receives and becomes energized with power from an electrical power source when the sensing means shifts from a conductive to a non-conductive mode. Normal gas pressures within the vessel maintain the pressure sensing means in the conductive mode. If gas pressure in the vessel falls below a preselected pressure, the pressure sensing means shifts to its non-conductive mode, whereby the signal means becomes energized and serves to inform passengers of the vehicle that the gas pressure is dangerously low.
