Rotor Fixed Wing Restraints


Military Vehicle Restraints


These qualified fixed and rotary wing restraint systems include two, three, four and five-point harnesses as well as inertia reels including the Mobile Aircrew Restraint System (MARS) and the MA-16 inertia reel system – the industry standard for pilot and co-pilot safety.

The recently developed Integrated Mobile Aircrew Restraint System (IMARS), which allows for greater range over the MARS system through the use of a “track and trolley” system.  Continuously innovating, Cobham’s Pretensioning Aircrew Restraint System (PARS) exemplifies the next generation in occupant survivability.  Providing maximum protection without sacrificing comfort, these restraints increase occupant survivability for pilots, co-pilots, troops, and gunners.  These restraint systems can be found on many platforms in the world including H-1, H-60, CH-47, CH-53, V-22 Tiltrotor, OH-58, and Apache helicopters.

The IMARS system, utilising Cobham’s inertia reel technology, enables aircrew members to complete a full range of required mission tasks by allowing freedom of movement and full access throughout the aft cabin and the ramp area.  As an evolution of Cobham Life Support’s Mobile Aircrew Restraint System (MARS), the Integrated Mobile Aircrew System (IMARS), originally designed for the CH-53K, interfaces directly with the airframe and consists of a “track and trolley” system.  This mobile inertia reel can be fixed to multiple set positions along the track, allowing for a greater range of mobility throughout larger airframe cabins.  During a crash event or hard landing, the inertia reel locks the webbing in place enhancing occupant survivability.

Key features of the IMARS include:

  • Allows for greater movement throughout the entire aft cabin and ramp area
  • Prevents occupant ejection from the aircraft
  • Reduces the likelihood of injury due to contact with interior surfaces
  • Restrains crew, limits motion and displacement during survivable aircraft crashes or hard landings
  • Automatically locks within one inch of webbing displacement

Cobham’s Ejection Seat Restraints, from Lap Belts to the Ballistic Powered Inertia Reel keep ejection seat aircraft pilots safe around the world.

Ejection Seat Lap Belts

Cobham’s lap belts, specifically designed for ejection seat applications, are constructed in two connectable sub-assemblies.  The sub-assemblies, one each for left and right hand, include the Cobham’s webbing adjusters which are integral to the buckle, providing tension adjustment and securing loads up to 5,000lbs.  All buckles have a low profile, eliminating the potential of snagging during an ejection.

Ballistic Powered Inertia Reel

Cobham Life Support’s Ballistic Powered Inertia Reel (BPIR) for ejection seats improves performance over legacy systems.  The modernized Cobham BPIR repositions the pilot’s back firmly against the seat to properly position the body during an ejection.

Key benefits of the Ballistic Powered Inertia Reel include:

  • Ideally suited for expanded aircrew population
  • Reduces the risk of spinal injury during an ejection sequence
  • Designed to fit all ACES II and ACES V ejection seats

The MA-16 Inertia Reel System, setting the industry standard in pilot and co-pilot safety, is found on all military rotary and fixed-wing platforms.

The MA-16 inertia reel system is the choice of all the U.S. Armed Services, Australian forces, and most NATO countries for non-ejection seat aircrew restraint systems. It can be configured for pilot, co-pilot, gunner, medic and crew chief restraint applications.

Eliminating the relatively high failure rate of legacy inertia reels, the dual sensing MA-16 inertia reel is a significant and innovative safety enhancement during a hard landing or crash impact.  The MA-16 has the capability to lock by sensing strap acceleration and omnidirectional impact forces reducing occupant flail and associated cockpit structure strike injuries during a crash.

Key benefits of the MA-16 Inertia Reel System include:

  • Dual sensing lock capability
  • Qualification to MIL-R-8236F
  • Zero failure rate during hundreds of tests and aircraft crash impacts
  • Significantly reduces occupant flail due to impact sensing capability
  • Reduces cockpit structure strike injuries

Demonstrated service life of at least 10 years

The Mobile Aircrew Vest Interface (MAVI) is designed to integrate with various aircrew vests currently in use by the US Department of Defense (DoD), law enforcement and search and rescue personnel.  The MAVI system provides a greater level of occupant protection during a crash event or hard landing than that of traditional safety equipment, including the Crewmember Safety Belt (CSB), used by US DoD personnel.

The Mobile Aircrew Restraint System (MARS) is the ideal safety solution for highly mobile military aircrew, law enforcement personnel and search and rescue teams.

To prevent highly mobile aircrew from being ejected during a crash event, hard landing or rough weather when working near open aircraft doors, Cobham Life Support developed the Mobile Aircrew Restraint System (MARS).  The MARS increases crew comfort and safety, replacing antiquated legacy systems by introducing inertia reel technology to mobile aircrew.

A derivative of the highly successful MA-16 Gunner’s Reel, an inertia reel with dual-mode locking capability qualified to the rigorous MIL-R-8236F specification, the MARS system significantly increases mission effectiveness and enhances occupant safety and survivability.

Cobham’s next generation Pretensioning Aircrew Restraint System (PARS) effectively improves occupant survivability during crash impact or hard landing.

Cobham has developed next generation inertia reel technology with the Pretensioning Aircrew Restraint System, designed to improve occupant safety by significantly reducing upper torso, head and neck flail during a crash event or hard landing.

Benefits over traditional restraint systems

With traditional restraint and inertia reel systems, occupant flail envelope can increase due to elongation of the restraint webbing, compression or “pack down” of inertia reel webbing which creates extra webbing payout. The Pretensioning Aircrew Restraint System (PARS) significantly reduces webbing slack immediately prior to a crash impact by sensing the impending impact and tensioning the restraint system. Functioning similarly to airbag deployment, a Crash Recognition Module (CRM) sends a signal to actuate the PARS prior to impact, removing harness slack and quickly securing the aircrew upper torso.  This pretensioning sequence limits forward motion of the upper torso, head, and neck, significantly reducing the opportunity for head/torso contact with the cyclic stick or other cockpit structure.

Completely modular system

The PARS system can be purchased as a new component with Cobham’s current MA-16 Inertia Reel System or as an upgrade to an existing, fielded MA-16 Inertia Reel System.


With the use of Cobham is an industry innovator enhancing soldier safety and survivability for military combat vehicles with its range of Combat Vehicle Restraint Systems.

Through our OEM Cobham Life Support has the capability to cost-effectively incorporate multiple design configurations to meet any ground vehicle requirement. We can offer two, three, four and five-point buckle restraint configurations as well as gun turret restraint systems that are designed to MIL-SPEC, FMVSS and OEM Specifications.

The Combat Restraints System was developed to enhance soldier
safety during mission accomplishment and in crash situations. They
are also intended to be used in various “off-road” vehicles as well.
Designed to withstand harsh environments, the restraint system
uses a rugged military style buckle and metal components which
offer easy cleaning and maintainability. The two-piece breakaway
will not snag on gear or present an issue with an occupant’s arm
getting caught in the “V” of a typical three-point harness. These
restraints are a derivative of the highly successful Improved
HMMWV Restraint System (IHRS) developed for the U.S. Army.
They address the occupant safety needs of personnel operating and
being transported within military tactical and combat vehicles as
well as off-road vehicles by:

  • Rapid donning and egress design.
  • Easy to find and use even while wearing gloves.
  • No snag hazards.
  • Remove and stow straps quickly.
  • Higher strap retraction spring rates.
  • Longer straps fit outsized occupants and over extra gear.
  • Easy open buckle with either hand or with hand injuries.
  • Buckle rotation limiters.
