    • A wheelchair lift apparatus which may be adapted for use in an existing motor vehicle in lieu of a seat structure removably coupled to the floor pan. The lift apparatus includes a motor driven horizontal screw for laterally moving a platform across the vehicle to exit the rear passenger compartment through a side door opening. The platform has a vertical side extension and carries a foldable wheelchair, for example, whose two sides collapse inwardly. The lift apparatus further includes motor driven linkage members for pivoting the platform and folded wheelchair from outside the rear passenger compartment toward the front of the vehicle. The platform and folded wheelchair are next vertically adjusted alongside either the driver or a front seat passenger door opening, depending upon whether the side door opening is on the right or left side of the vehicle. An additional motor driven linkage member is operative for downwardly pivoting the vertical side extension to a coplanar position with the platform so as to extend its effective surface for supporting the unfolded wheelchair, ready to receive the driver or front seat passenger; and a motor driven vertical screw for lowering and raising the platform and wheelchair.
    • 一种可适用于现有机动车辆的轮椅升降装置,代替可拆卸地联接在地板上的座椅结构。 提升装置包括用于使平台横过车辆横向移动的马达驱动的水平螺钉,以通过侧门开口离开后乘客舱。 该平台具有垂直的侧面延伸并且例如携带折叠的轮椅,其两侧向内折叠。 提升装置还包括用于使平台和折叠轮椅从后乘客舱的外部朝向车辆前部枢转的马达驱动的连接构件。 接下来,平台和折叠的轮椅与驾驶员或前排乘客门开口一起垂直调节,这取决于侧门开口是否在车辆的右侧或左侧。 附加的马达驱动的连接构件用于向下枢转垂直侧延伸部到与平台的共面位置,以便延伸其有效表面以支撑展开的轮椅,准备接收驾驶员或前座乘客; 以及用于降低和升高平台和轮椅的电机驱动的垂直螺丝。
