New Vehicle Safety SystemsVEHICLE AIRBAG Rollover Sensor ( inclinometer) 8. New Vehicle Safety SystemsVEHICLE AIRBAG Rollover Sensor ( inclinometer) Designed to measure the lateral and vertical acceleration, vehicle speed and roll rate to predict an impending rollover When the sensors detect a potential rollover, the control module triggers the curtain airbags and seat belt pretensioners 9. New Vehicle Safety SystemsVEHICLE AIRBAG New Style Curtain Airbag These sensors work in conjunction with a new style curtain airbag 10. New Vehicle Safety SystemsVEHICLE AIRBAG New Style Curtain Airbag "Safety Canopy" airbags In SUVs 3rd Row Seating Tethers located on the bottom corners of the bag, lock them in place to prevent occupants from being ejected. 11. New Vehicle Safety SystemsVEHICLE AIRBAG Safety Canopy Extrication Safety During cutting operations, rescuers should be aware that with the addition of the third row section, they may find two compressed gas inflaters on both sides of the roof rail instead of one These must be visually exposed before cutting operations begin 12. New Vehicle Safety SystemsVEHICLE AIRBAG Safety Canopy Concerns: These airbags have a controlled deployment speed and may deploy much faster than other airbags. The deployment zone is from the roof rail to the bottom of the window, the full length of the vehicle and the bag is about 5 inches thick 13. New Vehicle Safety SystemsVEHICLE AIRBAG Safety Canopy Concerns: Never lean through the window when approaching the vehicle. These deploy straight down about 18 inches, or to the bottom of the window and are capable of snapping a person's neck 14. New Vehicle Safety SystemsVEHICLE AIRBAG Safety Canopy Concerns: 15.

New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEM Roll Over Protection System (ROPS) refers to operator compartment structures (usually cabs or frames) intended to protect equipment operators and motorists from injuries caused by vehicle overturns or rolloversBackup power supply In case main power shuts off Remote Batteries in some vehicles Safety: Manual Deployment: Usually on the dash Takes approximately 4 seconds Personnel can now safely work and hold C-Spine 24. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEM 25. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMHistory One of the earliest ROPS systems was introduced by Mercedes in 1986. 26. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEM2 Types: 1. Flip-up type 2. Pop-up type 27. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMDeployment: 1. Hydraulic 2. Spring Loaded 28. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMActuator: 1. Inclinometer used to sense vehicle inclination and lateral acceleration 2. G-sensor that detects vehicle weightlessness if the vehicle becomes airborne 29. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMActuator: Sensors send information to a control module the same as SRS senors do 30. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMActuator Limitations: When the vehicle approaches a lateral angle limit of 62 degrees. When the vehicle experiences a lateral acceleration of approximately 3 Gs. When the vehicle approaches it's longitudinal angle limit at approximately 72 degrees. When a combination of longitudinal acceleration and longitudinal angle would cause the vehicle to roll over in the forward direction. When the vehicle becomes airborne and achieves weightlessness for at least 80ms. 31. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEM31 32. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMFlip-up Type: Deployable rollbars are concealed until activated. Flip up in less than three tenths of a second, much the same as a deploying airbag Example: Mercedes two seat roadster 33. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMFlip-up Type: 34.

New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMLocation: Others popup through holes behind the rear head rest. 37. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEM 38. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMExtrication Safety: The control module is just like the ones used with SRS systems. They contain capacitors that supply power to the system in case the battery is destroyed in the crash. The average capacitor drain time is 10 seconds. 39. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEM 40. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMExtrication Safety: EMS personnel should never lean over the back of a convertible as in holding C-Spine on an occupant. This would put the rescuer's head right over the undeployed roll-bar 41. New Vehicle Safety SystemsROLLOVER PROTECTION SYSTEMExtrication Safety: Rescuers must stay out of the deployment zone in these cases. The deployment zone is 20 inches straight up from the bars 42.
