Abstract: A vehicle of the "Volkswagen" minibus type with sliding side doors and rear engine drive has a tray-like subframe affixed centrally in a cut out portion of the main frame. The subframe has a front wall, a rear wall, one side wall and a planar bottom at a level well below the conventional floor level. A normally upstanding wheel chair ramp is pivoted to the bottom, on a fixed axis at the level thereof, in an opening in the opposite side wall of the rectangular subframe. The track for the side door has a section along the ramp. The lowered floor level brings the eyes of the patient down to window level.
