Personal Airbag Vests


Q: If a rider forgets to release the coiled wire when dismounting the horse, will the airbag activate?

A: Quite a strong pulling force is required to activate the airbag.
When dismounting, the rider may feel a strong tug and realizes that he/she has forgotten to disconnect the one-touch release.
However, be careful not to dismount a horse forcibly to avoid unnecessary activation.
Always disconnect the one-touch connector before dismounting a horse

A force of up to 30 kg. (66 lbs.) is required to detach the key and to activate the airbag. The dismounting rider will feel a strong tug well before deployment.

Q: What are the differences between vest models?

A: The Advantage offers the most hip protection, since it has dual telescoping airbags that deploy. It also has added padding behind the cartridge to minimize sound and the quickest (.09 sec) gas release mechanism. The new HLV-C, MLV-C and MLV-YC models have the largest side airbag and rear drop down bag. The MLV models are designed for both motorcycle and equestrian riders; there is a longer coiled wire option for the motorcycle. The LV and SV2 models were the original models that will probably be phased out; they have the smallest rear drop-down airbag. Additionally, the LV and SV2 do not have a heavy-duty keybox and keyball mechanism. The smaller 48cc cartridge for the LV and SV2 is located behind the airbag next to the rider unlike the other models, where the airbag is behind the Key Box.

Q: How much does an Hit-Air vest/jacket weigh?


Advantage Model About 34oz
SV-2 Model About 29oz
LV Model About 32oz
MLV and HLV Models MLV About 39oz; HLV 36oz (small) to 40oz (large)

Q: If an airbag is activated and inflated, can it be reused?

A: Yes, it can be reused over and over again provided it has not been damaged. Simply replace the gas cartridge using the handy tool attached to the vest.

How to replace a cartridge in the Advantage model

Q: If an inflated airbag is damaged by friction with the road surface in an accident, will it still be effective?
A: Yes, in fact the job of the airbag will already have been done - that is it will have dissipated the shock well before it is torn or damaged.
Q: How long will gas cartridge last?
A: Indefinitely, but it should be replaced if the surface shows any signs of deterioration or rust. (Of course, activated cartridges must be replaced.)
Q: Can I wear a light backpack or something similar overtop an Hit-Air jacket or vest?
A: Yes, just be careful that the straps do not press against the airbag interfering with its ability to inflate freely.
Q: How Mugen Denko developed the Hit-air?

Mugen Denko, LTD manufacturer of the Hit-air brand of Safety apparel is the world’s oldest manufacturer of airbag safety apparel. Mugen Denko began research and development work on an airbag system in 1995. The airbag jacket was invented and patented by Mr. Kenji Takeuchi. Three years later in 1998, Mugen Denko presented the world’s first airbag jacket for motorcyclists.

The U.S. lags behind Europe in its establishment of legislation that requires standards for all Personal Protective Equipment such as safety apparel. The European Directive on Personal Protective Equipment was made law in 1989. The U.S. still has not established this type of legislation that has been in effect in Europe for more than 20 years!

Under the European Directive on Personal Protective Equipment CEC 1989, any clothing claiming to provide protection from injury must be tested and labeled as complying with the relevant standard. This applies to all safety equipment not just motorcycle apparel.

Under this directive, a product can only be described as "protective" if it provides protection from injury, the term cannot be applied to products that provide protection from weather.

In 1999, Mugen Denko launched its airbag jacket in Europe where the safety standards are the highest in the world. In that same year Mugen Denko supplied some of the top apparel manufacturers’ in Europe with airbag systems, including world famous S P I D I of Italy, I X S of Switzerland and LOUIS of Germany.

These are the among the achievements of Mugen Denko over the past decade:

2000 Awarded Gold Trophy at the "Salon du Cheval" in Paris with the HP model.

2001 Launched the Hit-air jacket.

2003 Supplied the Police Headquarters in Japan with the airbag vests for the motorcycle police.

Obtained the CE* Marking approval by the EU for our airbag vest of MC Model. Launched the airbag vest for horse riding.

• 2009 S-System: Introduction of an improved key box (a device to activate the airbag system) cutting the deployment time in half. Commissioned the world famous Japanese Automobile Research Institute (JARI) to conduct an Airbag Jacket Deployment Test. Of the 20 tests the fastest deployment speed test T-09* was 120msec.

*The CE marking certifies that a product has met EU consumer safety, health or environmental requirements CE stands for " Conformité Européenne ".
