摘要： A combination access stairstep and elevator means for use in a passenger vehicle entryway. In its retracted normal position a passenger elevator platform member projects freely into the entryway part of its width below passenger deck level to serve as an access step for passengers who can ascend and descend on foot. Such platform member is mounted as part of a dual-arm parallelogram linkage mechanism on a guided, horizontally reciprocative carriage, the various parts of which in normal position are compactly stowed at a common level out of the entryway passage beneath the passenger deck. In order to accommodate disabled persons, the platform member may be fully extended outward in the entryway for use in elevating crippled persons and passengers in wheelchairs between deck level and curb or ground level. Grab rails with rail posts mounted on the normally projecting portion of the platform member can serve as a steadying aid to passengers in all positions of the platform member.
