SafeBalloon / warning triangle


prevent rear-end collisions after a car accident or break-down, Safe Balloon is a large-format combined warning triangle and airbag that other road users would find impossible to overlook. Safe Balloon is a warning triangle that
functions in much the same way as an airbag.
In the case of an accident, a crash sensor
activates gas injection and the balloon is
inflated. It can also be inflated by hand and as
such can also be used during a breakdown.
Its size and roof-top position make it highly
visible, even from a distance. The gas injection
mechanism is solar-powered so there’s no
need to change a battery.
