Stunt Industry

The air bags currently being used in the Stunt Industry are out of the dinosaur age. We have a far better bag for a great number of applications - just let us know what your requirements are. Our Krush Kushion (KK) technology allows for a far greater flexibility than the current crop of stunt air bags.




Our bags can be created in any shape. Need a 2m-wide bag that snakes between objects? No problem. And any part of that bag is safe to land on. And the top surface can undulate to create any profile or shape. This means that a very convincing large rock with a rounded top can be created and any surface of that rock would be safe to land on.


More than one person can land in the bag at the same time with almost no effect in the qualtiy of the landing and certainly no tendency for one person to bounce the other one off the bag. Depending on the height of the fall, they can be as close as 1m apart.


It is also easier to conceal the KK. Normal bags deform upon impact resulting in the ends of the bags folding up dramatically. If that bag was concealed behind objects – this leap upwards definitely ensures that it is no longer concealed! With KK the bag does not deform like this at all and would remain hidden even if the object it is concealed behind is the exact same height.


Since there are no vents to rip apart to allow the landing, as soon as the person rolls out of the bag it is ready for the next drop.



The current crop of stunt bags are effectively a 'bouncy castle' design and — to overcome the fact that this will simply bounce the impacting body off the bag upon impact — these bags have air releases to deflate the bag. But this does not make the surface ‘soft’ to land on.

The ‘Indent Response’ Principle: 

In a normal bag you have to land on your back because the surface is flat and taut and does not readily indent in a localised area. This is because the surface of the bag is under tension because it is holding in the air in the bag. In order for that flat surface to be indented by a body on impact, a large area of the top surface has to indent and an enormous amount of air has to be shifted from underneath the impacting body. This takes time and creates an ‘indent response lag’ and results in a relatively hard surface immediately upon impact.

By contrast – the Krush Kushion surface is not under tension at all. The top surface sheet  merely ‘floats’ on top of the cylindrical tube ‘fingers’ and to indent the surface sheet only requires the relatively small amount of air in the tubes immediately under the falling body to be squeezed out into the base bag below. This principle is exactly like the shock absorber in a car and the indentation is immediate. This means that protruding limbs (such as a head!) are indented into the surface of the bag far more efficiently and we have created for the first time ever an air bag where you do not have to land on your back to be safe. This is especially true if a stretchy fabric is used as the top surface in which case the KK becomes as soft as a fluffy pillow.

This means that with relatively lower drops it is possible to fall in any position in the bag even directly on the head. To illustrate this point - watch this video:



Not only are KKs softer to land in – you can also land anywhere on the bag – right up to the very edge! – without being bounced off. This problem with the current crop of airbags has caused serious injury and even death in the past. And because the KK design incorporates a multiplicity of tubes that cushion the fall – a catastrophic failure is almost impossible, unlike other bags where the explosion of the envelope would (and has) indeed cause catastrophic failure.
