Abstract
A wheelchair lift system having a stacking platform for use in conjunction with a vehicle. The wheelchair lift platform includes a first portion with an elongated support having fixed and moveable platform sections and a linear actuator powerable for moving between outboard and inboard positions. When stored in an upright, vertical orientation, one section of the platform is stored in a stacking or overlapping fashion behind the other section and stored upright inside the vehicle. Upon deploying the platform to its horizontal orientation, the two sections of the platform form one continuously coplanar lifting platform with the moveable platform section moving relative to the fixed platform section. A linkage system couples the moveable platform section for linear movement with the linear actuator for an orientation with the moveable platform section stowed as being stacked or overlapping with the fixed platform section. The actuator may further employ a pulley with a connector coupled to turn the pulley and a drive to move the platform.
