The explosion beneath a vehicle creates shock waves more destructive than dropping it 30 metres.
Although the armour stops shrapnel penetrating the vehicle the occupants are at risk from the devastating effects of the extreme shock from a mine blast.
Vital Seating & Systems Limited (VSS) has been manufacturing its modular lightweight crew seats for many years. At around 17kg the seat can be wall, ceiling or bracket mounted and either forward or side facing. The high specification includes options such as adjustable back rack, foot rest, adjustable head support, side restraints and a choice of a 2, 4 or 5 point harness. The quick release and seat folding systems aid fitment and provide added space saving, change of use and maintenance benefits.
The VSS Lightweight Crew Seat is custom made from high duty aluminium alloys, laser cut and precision welded to form an exceptionally robust seat. Each seat is fitted with award winning MouleTec® pressure relief cushions for extra comfort and wellbeing.
New Features Added
The company’s new range of lightweight crew seats keeps the best of the original seat. New features have been added to take account of changing threats, new requirements and customers specific needs. All VSS seats have been specifically designed to protect users against energy pulses from improvised explosive devices (IEDs), mines, and accidents.
The VSS ECD-Tech seat uses Energy Controlled Deformation Technology to supply extra blast deflection and decelerate occupants to safe levels. The unique ECD-Tech system permits the seat architecture to collapse in a controlled way. What’s more, unlike other technologies, there are no columns that could buckle under side loading so that the technology offers better protection during multi- directional blast events.

Custom Made Solutions
The very modular ECD-Tech seat can be easily adapted for any vehicle or application. This allows for the rapid development of affordable bespoke designs with minimum effects on performance levels. VSS provides a concept to in-service solutions for your seating requirements. The latest 3D CAD and finite element analysis software is used to design and prove the seat in full co-operation with the customer’s engineering team.
Whether your requirements are military, security or commercial contact us as soon as the project is conceived. Engaging our engineers early can make huge savings in time, re-design and overall project costs.
