Frontal Airbags
Self-Adaptive Venting Airbag
As the airbag inflates, the occupant position and distance sensors help determine the force of deployment. Then, a pyrotechnic actuator initiates a vent mechanism to adjust the performance. In some circumstances, the position of the occupant to the airbag suggests that more gas be allowed to escape from the module, allowing the energy to dissipate more quickly. This technology provides a solution for helping to meet OOP (out-of-position) requirements of FMVSS 208 while using a single-stage inflator.
PHI4 Module Integrated Concept
The PHI4 inflator technology is available as a single-or dual-stage hybrid inflator. The inflator output is varied with regard to the restraint system requirements and is used with advanced airbags. The bags can be packed to allow sequential and gentle deployment, fulfilling OOP requirements. Bag leakage and mechanical and thermal stress of the low-weight plastic housing is reduced because the bag-to-inflator and housing attachment is connected by the PHI4 inflator itself.
PPI5 Module Integrated Concept (MIC)
This concept combines effective restraint performance in a compact and low-weight package. The MIC design is based on the PPI5 inflator technology – a non-azide, single- or dual-stage pyrotechnic inflator. The system has adaptable inflator output, and adjustable gas mass onset; like the PHI4 Module, the PPI5 concept features an uncoated or coated 3D L-shaped bag. All components are packaged in a compact metal housing, using steel stamping technologies to provide design and packaging flexibility.
DI-10 Passenger Airbag Module
This passenger airbag module combines effective tailorable restraint performance with an improved package size and weight reduction. This design is a cost effective solution with four major components including the airbag assembly, plastic housing, bag retainer and the DI-10 disk inflator. The DI-10 disk inflator is a non-azide, single- or dual-stage pyrotechnic inflator.
Fixed Airbag with Asymmetric Configuration
While conventional driver airbags are generally round and rotate with the steering wheel, TRW’s fixed version has an asymmetric shape that allows changes to the deployment of the driver-side airbags. A circumferential gear wheel keeps the airbag module in a defined position. The system transmits direct forces from the steering wheel spokes to the steering column, eliminating any effects on the strength of the steering wheel. The stationary center area also allows for the integration of multi-function control switches.
Standard Concept Steering Wheel with Integrated Driver Airbag Module
Derived from a standardized design, this module allows complete system adjustment to meet customer styling requirements. In some cases, it is possible to simply replace the plastic steering wheel cover with a multifunctional item. Cushions can be adjusted to meet system requirements and are fixed in the airbag module via a retainer. This retainer can either be a ring, or a cage complete with inflator and vibration absorber. Single- or dual-stage inflators can easily be integrated into the system.
