Abstract: A foldable ramp assembly for providing wheelchair and patient trolley access from ground level to the interior of a vehicle cabin whose floor includes a pan which is configured to receive and retain the ramp assembly when not deployed. The ramp assembly comprises an elongate section which, when the assembly is deployed, engages at one end with the ground and at its other end through a hinge mechanism with the vehicle pan. The elongate section of the ramp assembly includes along each side edge an upstanding rigid flange member of a height sufficient to prevent a wheel or wheels of a wheelchair or trolley travelling along the ramp assembly inadvertently passing over one or other side edge of the ramp assembly. The pan includes side channels which are inclined downwardly towards openings formed in an external surface of the vehicle cabin and which are dimensioned to receive said flange members when the ramp assembly is located within the inclined pan.

Abstract: A deployment mechanism for a bariatric ramp which has a drive motor pivotally secured to one side of the ramp platform. The deployment mechanism includes a lever located in a housing on the opposing side of the platform ramp. One end of the lever being connected to a platform pivot bar and the other end being connected to a traction gas spring secured within the housing. The spring mechanism comprises a drive shaft having a first and second torque levers located either end of the drive shaft. The drive shaft being rotatable as the platform is deployed such that the torque levers move between a first position whereby only the first torque lever acts on the spring and to a second position whereby neither first nor second torque levers act on the spring and to a third position whereby only the second torque lever acts on the spring.
