Abstract
Abstract Arrangement for a lift adapted to a motor vehicle, comprising a lifting platform capable of moving between the vehicle and a floor. The invention provides a simple device for achieving a reliable and efficient lift arrangement, for example, for use by individuals in wheelchairs who wish to move between the inside and the outside of a vehicle without the help of an assistant, and without additional ramp or lift arrangements. The platform is attached via a scissor mechanism to a source of power for the platform, so that the platform, upon actuation of the power source, moves between a lower and an upper position, one of which at least is situated at a different level with respect to that of the attachment of the scissor mechanism to the source of power.
