The harness

How your harness holds you, protects you and connects you to the wing, and the leg-strap habit that keeps you in it.

In this lesson you will

On the training hill you will clip in and out of your harness dozens of times a day. It is your seat, seat belt and crash protection, and it carries your reserve.

The most dangerous harness mistake is not exotic. Pilots keep launching with their leg straps open, and some have died falling out minutes after launch¹. This lesson builds the habit that prevents it.

Parts of a harness

School harnesses are robust seat-plate harnesses built for training². You sit on the seat plate, held in by a leg strap round each thigh, shoulder straps and a chest strap that joins the two sides. The risers clip into two main carabiners at the hang points. Behind and under you is a back protector³, the reserve container sits under the seat, behind your back or at the front⁴, and the speed bar hangs under your feet⁵.

A reversible harness turns inside out into your rucksack². A pod harness, with a cover over the legs, comes later: pods can hinder the launch and make riser twists after collapses more likely, and the BHPA teaches them only after Club Pilot⁶.

Figure: A school harness from the side. Find the leg strap, the chest-strap buckle and the main carabiner; you check all three before every launch.

Closing it, every time

Fit a new harness by hanging in a simulator before your first flight, with the reserve fitted: a hang test. The leg straps should let you slide back into the seat after launch without using your hands, and no strap should be over-tight⁷.

Putting on your harness, with your instructor

Look the harness over before you step in.
Cue Straps untwisted, buckles undamaged, reserve handle secure, pins in place⁸⁹.
Close both leg straps before the chest strap.
Cue Each buckle clicks shut.
Why An unexpected inflation with only the chest strap done can drag you over by the throat¹⁰.
Pull each buckle apart and wiggle it.
Cue It stays shut however you tug it.
Why Buckles can wear, corrode or be faulty⁸.
Close the chest strap at its marked width, then clip in with both carabiners locked and the risers untwisted.
Why An unsecured carabiner can open in flight¹¹.
Before every launch, check again by hand. If anything interrupts you, start from the beginning.
Cue You can name every buckle you touched.
Why Distraction is a main cause of missed checks¹²¹³.

Taking it off, open the chest strap first and the leg straps last¹⁰.

Leg straps and anti-fall-out systems

With the leg straps open, nothing holds you in the seat. As the wing rises it pulls the carabiners up, and the harness slides up your body instead of lifting you by the seat¹⁴; off the ground, you would hang in a harness that is not holding you¹⁵. In a few months before July 2023 the German federation (DHV) received four reports of accidents with unclosed buckles, three of them caused by a distraction while getting ready¹.

That is why many harnesses now have an anti-fall-out system. With Mac Para’s Get-Up, the chest strap cannot be closed until the leg straps are, and an unfastened harness lifts away from you as the wing rises; Gin’s T-lock and Supair’s Safe-T-bar do the same job¹⁶. Harnesses type-tested in Germany must now make falling out impossible in any position¹⁷.

They reduce the risk but do not replace your check before every launch: pod covers and front reserve containers make open straps especially easy to miss¹⁸¹⁹.

Safety-critical Harness riding up? Abort.

If the harness is pulled unusually far up your body as the wing inflates, your leg straps are open: abort at once¹⁴. The DHV’s last resort, only if it is too late to stop, is to raise your arms above your head and slip out of the harness before your feet leave the ground¹⁵. If it ever happens in the air, see Aborts and launch accidents.

Back protection

Harnesses come with a back protector to damp the impact on your spine in a hard landing, and German rules require one on every harness³. The three types, sometimes combined, are airbags that fill in flight and vent on impact, hard foam that crushes in a controlled way, and foam inside a closed bag³. In the certification drop test a dummy of at least 50 kg111 lb falls from at least 1.65 m6 ft, and the peak deceleration must stay under 50 g²⁰.

Airbags fill through an intake, so makers add foam, springs or wire to pre-inflate them; check the intake is open before you fly²¹. A protector also floats and can hold a pilot face down after a water landing²²; see Trees, water and power lines.

That matters: in BHPA reports, most serious spinal injuries were lower-back compression injuries²³. A protector reduces them but cannot remove the risk: landing seated or on your back is dangerous even with one, and standing up before you land is your main protection²⁴.

Myth vs fact

Myth: With a big airbag I can land sitting down.
Fact: A protector only reduces injury when a landing goes wrong. Landing seated is dangerous even with one²⁴.

Plan every landing on your feet; the protector is for the landing you did not plan.

Main carabiners

Your main carabiners carry your whole weight. They are either auto-locking aluminium alloy, breaking at about 16 to 18 kN, or heavier stainless steel at about 26 to 28 kN²⁵. Check before every flight that both are fully closed and locked: a carabiner not secured as its manual describes can open in flight¹¹. In 2024 German pilots threw their reserves three times after a quick-release carabiner opened in flight²⁶.

Even screw-gates are disputed: one maker says vibration can work them open, another builds one to a paragliding connector standard²⁷. Use what your harness maker supplies or approves.

When to replace them is disputed too. Every source sets a limit of 5 years, but the flying-hour limits differ widely²⁸:

Source	Replace after
Supair, Gin	5 years or 500 h
Austrialpin	5 years or 1,500 h from first use
Woody Valley	5 years or 2,000 h

The wear is fatigue from vibration. Replace any carabiner that is damaged or has taken a hard impact, even if it looks fine, because cracks can be invisible; otherwise follow your maker’s figure²⁸.

Chest-strap width

The chest strap sets the distance between your carabiners, and that changes how the wing feels²⁹:

Wider: more feedback and easier weight shift, but less stability; in turbulence it is easier to fall towards a collapsed side.
Tighter: the wing feels more solid, but you get less feedback, weaker weight shift and a greater risk of riser twists after a violent asymmetric collapse.

Figure: The same pilot with the chest strap set tighter, as the manual says, and wider. The width is the distance between the carabiner centres.

Sources disagree on the width. Certification uses test widths by total weight: 40 cm16 in under 80 kg176 lb, 44 cm17 in for 80–100 kg175–220 lb and 48 cm19 in above, each ±2 cm±0.8 in³⁰. Makers’ recommendations differ: Ozone suggests about 42–48 cm17–19 in on its school wing, and Mac Para warns that going more than 5 cm2 in from the recommended width changes the wing’s basic character²⁹. Set it to your wing’s manual with your instructor, then leave it.

Speed bar and reserve

The speed-bar line runs through pulleys on the harness and clips to the risers with Brummel hooks. Set its length hanging in a simulator, so the released bar does not pull the front risers. Makers disagree on where the resting bar should hang, from at least 15 cm6 in below the seat front (Gin) to no more than 10 cm3.9 in (Woody Valley), and it is not a step for getting into the seat⁵.

Harness and reserve are checked as one system by a qualified person, with you hanging in a simulator⁴. The reserve parachute covers the whole chain.

Common mistakes

Common mistake Getting distracted at hook-in

Symptom: You cannot remember whether you closed your leg straps.
Cause: Someone spoke to you, the wind changed, or you rushed the restart after an aborted launch.
Fix: Start the whole check again from the beginning. A buddy check helps but does not replace your own¹²¹³.

Common mistake Fiddling with the harness straight after launch

Symptom: Near the slope you let go of a brake to wriggle into the seat or reach for the speed bar.
Cause: Leg straps set too tight, or impatience to get comfortable.
Fix: Fly away from the terrain first, then settle in. Adjust the straps in a simulator so you can sit back without your hands³¹⁷.

Instructor's note Every harness is different

Buckle layouts, front containers and leg loops vary. Treat any new or borrowed harness with extra care, and check hidden buckles by touch¹⁹.

Standards differ The harness in the pre-launch check

Common ground: Every system checks the harness connections before launch³²³³³⁴³⁵. The BHPA, DHV and SHV add that an interrupted check starts again¹². Full checks are in Setting up and the pre-flight check.

USHPA (USA): A connection check before every inflation, with risers and lines clear³².
BHPA (UK): H for harness covers both leg straps, the chest strap and both carabiners, plus speed system and reserve; leg straps go on before the chest strap³³¹⁰.
APPI (international): B.E.S.A.F.E.: B for buckles covers leg, waist and chest straps, helmet and carabiners³⁴.

Questions students ask

Does an airbag protect me during the launch?

Makers say mostly: they pre-inflate airbags with foam, springs or wire, and Gin says its bag is mostly full before you are airborne²¹.

How tight should the leg straps be?

Loose enough to slide back into the seat after launch without using your hands⁷.

My harness has a get-up system. Do I still need to check my leg straps?

Yes, every time. The check before every launch still includes your leg straps, and pod covers or front containers can hide open ones¹⁸¹⁹.

Key points

Leg straps first, then the chest strap; tug every buckle; restart the check after any interruption.
A harness riding up your body as the wing rises means open leg straps: abort at once.
Anti-fall-out systems reduce the risk but never replace your hand check.
A back protector reduces injury in a bad landing; it never makes a seated landing safe.
Check carabiners closed and locked every flight; replace them after damage, a hard impact or the maker’s limit.
Set the chest strap and speed bar to the manual with your instructor.
