<p>The device (1) has a bottom arm (4) connected to a top arm (5) by a pivot joint (7), where the top arm rotates around a horizontal axis relative to the bottom arm. The top arm has an L shaped end piece connected and rotatively cooperating with an approach ramp (7). The ramp rotates around another horizontal axis of the end piece, so that an articulated arm (2) guides the ramp to pass from storage position inside a vehicle to deployed position outside the vehicle. The ramp is supported on and connected to the articulated arm by the end piece in the storage and deployed positions.</p> |
