A vehicular wheelchair lift with a power controlled safety barrier for physically blocking a wheelchair from inadvertently rolling off a platform of the wheelchair lift during use. The power safety barrier utilizes a linkage mechanism to open or close a roll stop. The linkage mechanism includes a pair of linkage bars and a flexible linkage member to mechanically connect the roll stop to a power actuating device. The roll stop is pivotably mounted to an outer end of the platform. The roll stop is required to open and close relative to the platform according to the relative platform positions. When the platform is in the ground position, the roll stop is opened substantially in a horizontal plane and is an extension of the platform for unloading the wheelchair. In the powered control aspects, during the wheelchair lift transition period when platform is off the ground position, the roll stop is actuated to the closed position before the wheelchair lift can be operated. Reversely, during the wheelchair lift transition period when the platform is lowered to the ground, the roll stop cannot be actuated to the open position until the platform has reached the ground position.

Power safety barrier for wheelchair lift

A wheelchair lift for use in conjunction with a vehicle having a door opening and a floor. The wheelchair lift includes a foldable platform assembly having two platform plates hingeably connected along their adjacent edges which are automatically foldable and stowed at one side of the vehicle door opening.

Foldable platform wheelchair lift

A wheelchair lift, as for use with a vehicle, includes a platform for receiving a wheelchair carried as a pivot mechanism including two pairs of cooperating parallelogram structures adopted to be affixed to a vehicle for moving the platform between loading, entry and stowed positions by hydraulic actuation. A bridge plate structure is actuated by the pivot mechanism to be positioned as a bridge into the vehicle in the entry position, as a roll stop when a wheelchair is being carried and as a latch unit in the stowed position. A cam-cable mechanism actuates the bridge plate and the parallelogram structures of each pair are interlocked in moving between the stowed and entry positions.
