The present invention provides in particular a device for reinforcing a hollow motor vehicle bodywork element () of closed right section, the device being characterized by the fact that said element () has means () suitable for subjecting its inside space (E) to a shock wave or pressure wave on detecting an impact, such that the energy generated by said wave is sufficient to deform the element by increasing its section.

Device for reinforcing a hollow structural element

The present invention relates to a gas generator device used in automobile safety to inflate an airbag. This device is characterized in that it comprises at least one gas source for inflating the airbag and at least one gas outlet orifice, called the first orifice, for gas to flow into the airbag, characterized in that it includes means for making the gas pass through other gas outlet orifices, called second orifices, which are distributed over the device so that it is given a neutral-thrust configuration when it is initiated, although not in service, the device also including means for closing off these second orifices when the device is in service, so that when the device is initiated, the gas passes via the first outlet orifice.

Gas generating device

The present invention relates to a hybrid gas generator (), used for motor vehicle safety to inflate an airbag, comprising a body () containing an ignition device () and a reservoir () connected to the body and containing a pressurized gas (), together with initially closed-off discharge orifices (). The body possesses a first pyrotechnic charge () capable of generating a quantity of gas which, coupled to the volume of gas () contained in the reservoir, allows the airbag to be inflated in a time period of less than 50 milliseconds, and a second pyrotechnic charge () capable of generating, after combustion of the first pyrotechnic charge, a quantity of gas sufficient to keep the airbag inflated for a time period of several seconds.

Hybrid gas generator for a side airbag applied to motor vehicle safety

A hybrid gas generator unit ( ) may be used to inflate at least one side airbag. The hybrid gas generator contains a pyrotechnic gas generator ( ) produced using a body ( ), which contains an igniter ( ) and which is provided with first and second ends ( ), and a flexible element ( ), which contains a pyrotechnic charge ( ) and which is attached to the second end of the body; and a pressurized gas ( ) reservoir ( ) attached to the pyrotechnic gas generator at the first end of the body. In the hybrid gas generator, the igniter is capable during operation of initiating the combustion of the pyrotechnic charge contained in the flexible element and of causing the pressurized gas contained in the reservoir to be released.

There is disclosed an electropyrotechnic igniter which contains two ignition heads each having a body containing a resisitive heating element and a pyrotechnic ignition composition. The two ignition heads also include a means of dialogue and of triggering coded information and a means of storing electrical energy. The igniter also includes external connection means intended to be connected electrically to an electronic control unit. The igniter is intended to be used in motor vehicle safety, particular to constitute the ignition device of a gas generator associated with an airbag.

Electropyrotechnic igniter with two ignition heads and use in motor vehicle safety

A safety device housed in a motor vehicle and used in the field of automobile safety has an impervious inflatable metal bag fixed to a support, a pyrotechnic charge, and an ignition device intended to be connected to a source of electrical current. The bag includes a first metal sheet which has a central orifice, an intermediate fixing zone attached to the support and a peripheral fixing zone and a solid domed second metal sheet which has a peripheral fixing zone. The two metal sheets are fixed together at their peripheral fixing zones. The pyrotechnic charge is contained in the bag.

The invention relates to an initiator for a pyrotechnic gas generator intended for motor vehicle safety. The initiator ( ) is built from a circuit support ( ) on which conductive strips are printed which include electromagnetic protection and the ends of which are joined together by a resistive element covered with a thermosensitive charge ( ). The conductive strips are connected to an electric cable ( ). The support ( ) is coated in a cylindrical overmoulded insulation ( ). A fragmentable cylindrical cap ( ) containing an igniter composition ( ) forms, together with the initiator ( ), an igniter ( ) for pyrotechnic generators intended for motor vehicle safety.
