Mounting Boxes & Risers

ISRI seat mounting boxes/risers are used to provide a secure, engineered base for installing ISRI seats into various vehicles, particularly heavy commercial vehicles, construction, and mining equipment.

Their primary function is to:

• Adaptation for Vehicle Specifics: Different vehicles (trucks, buses, construction equipment, trains) have varied floor pan designs and mounting points. The risers act as an adapter between the universal seat mechanism and the specific vehicle’s chassis.
• Achieving Correct Ride Height: They help position the seat at the optimal height for the driver, ensuring an ergonomic and comfortable driving posture, which is especially important in heavy-duty vehicles where operators spend long hours on the road.
• Ensuring Safety and Compliance: The risers are engineered to meet specific international safety and quality standards (e.g., ISO 6683 and ISO 7096) related to seat belt anchorages and vibration dampening. This ensures the entire assembly performs safely in the event of an accident and conforms to all relevant vehicle design rules.
• Providing a Stable Base: The riser provides a robust and stable foundation for the seat’s complex suspension system and adjustment mechanisms (like air suspension and horizontal isolators) to function correctly and absorb shocks and vibrations effectively. 

Essentially, an ISRI mounting box/riser is a vital component that allows the advanced, ergonomic ISRI seat to be seamlessly integrated into a vehicle, ensuring the driver benefits from maximum safety and comfort. 

We strongly recommend that all installations, especially in heavy machinery, conform to relevant standards, which often necessitates the use of approved mounting components like these boxes. 

Key features of the mounting box and related components include:

• Structural Integrity and Durability: The box is constructed from high-quality, heavy-duty materials designed to withstand the tough conditions and heavy use common in commercial vehicles, mining trucks, and heavy earthmoving equipment.
• Mounting Points and Compliance: It provides the necessary, structurally sound anchorage points for the entire seat assembly and, critically, for the seat belts. This design ensures compliance with stringent safety standards and Australian Design Rules (ADR 4 and ADR 5, for example) regarding seat belts and their anchorages, which is vital for safety in the event of an accident.
• Integration with Suspension System: The box is specifically designed to integrate with the seat’s suspension technology (often self-leveling air suspension), housing components like the air suspension system itself, shock absorbers, and air fittings.
• Control Mounting: Operating elements for various seat functions (e.g., height adjustment, air dump valve, backrest recline) are often intuitively positioned on or around the mounting box for easy access by the driver.
• Accessory Provisions: The design typically allows for the fitment of various accessories, such as tether straps, armrests, and even canvas or Kevlar seat covers.
• Vehicle-Specific Compatibility: Mounting boxes are often supplied with universal or specific brackets to ensure proper fitment into a wide range of vehicle cabs (e.g., Scania, Volvo, Isuzu).
• Left and Right-Hand Control Options: They are available in configurations that accommodate both left-hand and right-hand drive vehicles.
