Abstract
The present invention provides an airbag apparatus for a two-wheeler vehicle. The airbag apparatus includes at least one front airbag mounted near each leg of a rider of the two-wheeler vehicle, the at least one front airbag to be deployed and inflated for protecting the knees, legs and feet of the rider during emergency conditions. Further, the airbag apparatus includes at least one rear airbag mounted near each leg of a pillion rider of the two-wheeler vehicle, the at least one rear airbag to be deployed and inflated for protecting the knees, legs and feet of the pillion rider during emergency conditions. Yet further, the airbag apparatus includes at least one inflator configured to supply inflation gas to the at least one front airbag and the at least one rear airbag when activated. Finally, the airbag apparatus includes at least one sensor configured to track at least one safety parameter of the two-wheeler vehicle and activate the inflator, when a predetermined threshold of the at least one safety parameter is reached.
