Impact Energy Absorbing Boss
Designed, Developed and Manufactured by Simpact
The impact energy absorbing boss has been designed, developed and manufactured by Simpact for use by their Niche vehicle customers wanting to achieve ECE-R12 European Type Approval. The boss is retrofitted to an existing steering column assembly between the column and steering wheel.
Lightweight Aluminium Design
The lightweight aluminium design is highly innovative as the rotationally symmetric part is manufactured from a single length of aluminium extrusion. The two stage energy absorbing concept is designed to meet both the Annex 4 (body block) and the Annex 5 (headform) part of the ECE Safety Regulation No.12.
Validated by Drop Testing
The design has been developed from concept to detailed part using the appropriate CAD design and finite element tools. This includes the in-service load cases that you would expect for such a component. The complete system including steering column and steering wheel was tested experimentally by high speed drop testing.
