An electric line cutter device for high voltage busbars has a two-part housing, a piston, an igniter and a busbar. The upper housing includes a cylinder, cuboid or prism chamber. The lower housing also includes a cylinder, cuboid or prism chamber. The piston is contained inside one of either the upper housing chamber or the lower housing chamber. Upon igniting the igniter, the piston breaks a portion of the busbar moving the piston and the portion of the busbar into the opposite chamber thereby stopping the electric current flow. The piston is at least partially formed as an insulator to prevent electric discharge. The piston design together with chamber design includes integrated 'squeeze areas' and 'blow channels' for the appearing arc. A channel system outside or from inside the piston allow the pyro gases to push the arc plasma into a filter system to cool down the gases.

An airbag cushion assembly () has an airbag cushion () and an inflator (). The airbag cushion has a plurality of inflatable chambers including a primary chamber () configured to receive inflation gas and one or more additional chambers () for receiving inflation gas from the primary chamber (). The inflator () is in communication with, or open to, the gas inlet of the primary chamber (). One or more of the additional chambers has one or more one-way gas flow check valves () for receiving inflation gases into the chamber and preventing the received gases from back flowing to maintain the one or more additional chambers at full inflation when the airbag cushion is inflated and loaded.

An igniteractivated blocking deviceblocks a fluid lineadapted to carry fluid. The blocking devicehas a housingdisposed about the fluid line, a pistonhoused in the housing, and an igniterthat when activated propels the pistonto block the fluid line. The ignitergenerates a shock wave to move the pistonto block the line. The pistoncrushes or squeezes a portion of the lineto close the line.

An electric fuse box or junction box assembly has a high voltage electric line cutter assembly inside an electric fuse box or junction box. The assembly has a box housing for connecting a plurality of electrical lines or connections to a power source. The housing has a pair of mounting stanchions for affixing the high voltage electric line cutter assembly with an electric current carrying busbar having a pair of stub ends. Each stub end of the busbar for carrying electric current from the power source to the plurality of electrical lines is secured to one of the mounting stanchions. Each mounting stanchion has an attachment platform for attaching and supporting the stub end of the busbar and an underlying chamber below the attachment platform for receiving exhaust gases generated when the high voltage electric line cutter assembly is activated.

A method of forming an airbag cushion (A) has the steps of providing placing the cushion in a vacuum bag () and evacuating the air shrinking the airbag cushion (A) to a compacted size; conforming the airbag cushion to a predetermined shape; placing the airbag cushion (A) in a high temperature environment between +50&#xb0; C. to +140&#xb0; for a predetermined time to thermally set the fabric material () to maintain the compacted airbag cushion (A) to the predetermined shape; and releasing the vacuum and removing the thermally set airbag cushion (A) from the vacuum bag ().

A side airbag cushion (A orB) has a front side panel (), a rear side panel (), a top panel () spaced between the upper edges of the front and rear side panels (), and a bottom panel () spaced between the lower edges of the front and rear side panels (). The top and bottom panels () are configured to create a contoured or concavity () shaped fully inflated side airbag cushion with a larger sized forward end () volume and with a smaller sized volume at the occupant mid-location () wherein the inflated airbag cushion fills the gap between the door trim () and the occupant ().

Shaped airbag

An airbag module, in particular for a side airbag, has an airbag and a fastening element, preferably having a longitudinal profile, on which the airbag is arranged directly or indirectly via an airbag module housing. The fastening element has a substantially U-shaped cross-section and is constructed in such a way as to grip in a complementary form-fitting manner around a structural element of a vehicle.
