Abstract
A ramp structure for a mobile platform includes a housing structured to be mounted on the mobile platform, and a ramp member coupled to the housing so as to be movable with respect to the housing. At least one airbag is operably coupled to the housing and is configured to be inflatable to move the ramp member from a retracted position to an extended position in which the ramp member defines a ramp structured to guide a wheel of a subject vehicle onto an exterior surface of the housing.
