About Custom Restraints

Working with military OEM customers, IMMI® designs, develops and manufactures restraint systems that are easy to use and comfortable to wear. Thorough testing and durable construction mean a longer field life and better endurance in the harshest conditions.

IMMI offers extensive options for customizing restraint harness components, including buckles, switches, wiring harnesses, retractors and connectors, to meet the requirements of each military vehicle design. If the application requires upper torso restraint or integration with vehicle safety systems, IMMI engineering teams can develop systems to meet customer needs.
