With unmatched protection, the Spartan Advanced Protection System® (APS)[1] is an all encompassing restraint system engineered specifically for the firefighter. The APS incorporates five industry-first safety features, in addition to several industry standards, further protecting occupants to and from the scene.

Outboard sensors Industry First outboard sensors

Spartan’s state-of-the-art outboard sensors protect occupants from multi-angle impacts in the cab. These sensors are mounted at the outer perimeter of the cab providing a “zone of safety” inside the cab. Each sensor communicates back to the restraint control module that monitors which airbag should deploy and under what conditions.

Driver Curtain Airbag

Side impact protection Industry First outboard sensors

The outboard sensors allow for faster deployment of airbags and protect occupants from side impact collisions, rollovers and occupant ejection for all persons in the cab. Spartan is the first, and only, company in the industry whose airbags protect cab occupants from side impacts, unlike their competitors, whose side airbags only deploy in the case of a rollover.[3]

Full side curtain airbags

Full side curtain airbags Industry First airbag

APS full side curtain airbags protect occupants from a side impact or a rollover event. Spartan’s front side airbags are up to three times larger than their competitor’s. Each of Spartan’s rear side airbags are custom sized for the crew area of every cab they build, with the largest rear side airbag covering seven times the area of their competitor’s.[3]

Driver knee airbags

Driver knee airbags Industry First airbag

The new driver knee airbags lock the lower body in place so the upper body can be slowed by the seat belts and caught by the steering wheel airbag. This protects the driver against contact injuries resulting from hitting the instrument panel or other interior points of contact.

Steering wheel mounted driver airbag

Steering wheel mounted driver airbag airbag

In the event of a front impact collision, the upper body is slowed by the seat belt and caught by the steering wheel airbag. This protects the driver against contact injuries resulting from hitting the instrument panel or other hardware.

Officer knee airbag

Officer knee airbag airbag

The impact resulting from a front on collision could do serious damage to the lower body. The officers’ knee airbag absorbs much of the forward momentum, locking the lower body in place while the upper body is slowed by the seat belts protecting the passenger from deceleration injuries.

Advanced seat belts

Advanced seat belts Industry First seatbelt

The APS features an industry first, advanced seat belt system which pulls the occupant into the seat in the event of an impact, or rollover. These intelligent seat belts have pyrotechnic pretensioners in the retractors instead of just a buckle. Spartan validated that pretensioners in the retractor provide more force during the initial lock. After the occupant is pulled into the seat, load limiters release some of the webbing to control the occupant’s deceleration into the airbag system. These new seatbelts help control the strain on each occupant while reducing pressure on the chest and torso, reducing seatbelt related injuries.

Reinforced cab structure

Reinforced cab structure cab

Spartan Chassis custom cabs are constructed with reinforced roof structures, C-channel roof supports, reinforced engine compartments, triple reinforced box front bulkheads, and reinforced front & rear step assemblies. Spartan participates in third party testing to validate the safety our cabs including, roof crush, front impact, roll stability control, airbags, seat mounting and seat belt restrain system validation. This ensures the safest Emergency Response cabs on the market.

Electronic stability control

Electronic stability control[2] control

Electronic Stability Control (ESC) is a system that helps maintain vehicle stability and aids in reducing vehicle rollovers. ESC monitors the vehicle’s rollover threshold and activates a computerized device to slow the vehicle when the threshold is approached. The prevention of accidents not only protects individuals, but it also saves your department valuable time and money.

Interior safety lighting
