In-floor ramp assembly with overhead rail, lateral guides, and energy absorbing end stops

Abstract

A ramp assembly includes a guide rail at least partially disposed in a void space between ramp platform edge guards, above a ramp platform, and below a ramp cover to reduce the overall height/thickness of the ramp assembly as compared to prior art ramp assemblies that locate guide rails below the ramp platform. A transition flap assembly provides lateral guidance for the ramp platform and carriage assembly. The transition flap assembly and ramp platform assembly engage to ensure at least approximate contact between the transition flap and ramp platform when the ramp platform is deployed and to maintain a spaced relationship between the two when the ramp platform is between the deployed and stowed positions. A sliding door track is configured to provide structural reinforcement to a track pan area of a floor. The guide rail may include an enhanced end stop to decelerate the ramp platform over a distance.
