Market Trend
- To realize comfort and intelligent in-cabin requirement, more OEMS plan to used ZGS seat in the cockpit.
- Safety for ZGS seating position is the challenge that to be faced immediately.
ZGS Seating Position Safety Challenge
- High possibility of submarining
- High spine load
- Unfavorable belt-neck interaction
- High abdomen pressure
Active System
- Active occupant repositioning during pre-crash phase
- Using vehicle based external sensor set and our occupant monitoring system
- Dedicated algorithm to trigger pre-crash repositioning
- Using powerful seat integrated motor as actuator for repositioning
Passive System
- Key safety Seat Energy Management (SEM) components include SEM-C, SEM-B, SEM-U
- SRAB, ABTS, AP3
- Ignition strategy during crash
ZGS Safety Solution helps to achieve C-IASI demand
- SEM-U works as key control unit for ZGS with E-locking algorithm, pre-crash safety algorithm and ignition strategy
- SEM-B&C enable controllable energy absorption during seat passive reposition with flexible integrated approach
- E-locking SBS can be used for various seatback angle
- APT ensure high webbing pull-in for pelvis control
- SRAB support to absorb energy during crash
SEM-C (Seat Energy Management Module for Cushion)
SEM-B (Seat Energy Management Module for Seatback)
SEM-U (SEM Control Unit)
