An initiator suitable for use with airbag passive restraint systems and which does not use pyrotechnic materials is disclosed. The initiator provides an electrically actuated igniter which ignites an adjacently stored non-pyrotechnic fluid combustible material which may comprise a mixture of a fluid fuel and a fluid oxidizer, a fluid monopropellant or a fluid exothermically decomposable material. A sub-assembly of the non-pyrotechnic initiator with a fuel containment chamber and inflators which use the non-pyrotechnic initiator are also disclosed.

[ We claim:] [1.] An initiator and fuel supply assembly for use with an initiator for an airbag passive restraint system, comprising:a first fluid retaining chamber,an electrically actuated igniter device selected from the group consisting of spark gap and resistive bridge elements and located in said first fluid retaining chamber,electrical leads operatively connected to said igniter device,a non-pyrotechnic oxidant-containing fluid combustible material stored within said first fluid retaining chamber in direct contact with said element of said igniter device,a second fluid retaining chamber adjacent to said first fluid retaining chamber, anda fluid fuel stored within said second fluid retaining chamber, wherebythe application of an electrical signal to said leads causes said igniter device to develop sufficient energy to ignite said combustible material causing both of said first fluid retaining chamber and said second fluid retaining chamber to open dispersing said fluid fuel into the inflator.
