Abstract: A semi-ambulatory companion seating system including a base unit assembly, a carriage assembly, and a pivotable seat support assembly. The base unit assembly includes spaced apart side rails, each having an external and an internal track. Each of the internal tracks are generally horizontal throughout, and each of the external tracks has a generally horizontal section terminating in an inclined section. The carriage subassembly includes a generally rectangular framework having six rollers to move the carriage on the internal and external tracks. Four rollers are guided in the internal tracks. Two rollers, mounted on an outrigger disposed along the inboard end of the carriage assembly, are guided in the external tracks. The outboard end of the carriage assembly includes an axle bushing for receiving an axle of the pivotable seat support assembly mounted thereon. The seat assembly includes a seat base box-plate assembly having holes aligned to receive the bolts of a standard vehicle seat.

Abstract: Passive rotary wheelchair lift that is retrofittable in transit vehicles on either the forward or rearward edge of a side double-door step well. The lift employs in its preferred embodiment a double slide tube having a box frame with a cross header. A hydraulic cylinder actuates a pair of chains, one descending down each lift tube to operate the vertical lift. A manual hand pump is provided in the case of power failure. Secured to the bottom of inner telescoping lift tubes is a plate carrying a power actuator for rotating the lift platform from a deployed horizontal position to a vertical stowed position. In the stowed position the platform is approximately 26 inches in length and 36 inches in width. The platform has one or more slide-mounted extension sections which permit the platform to extend out to a full 51 inches. Manual or power-actuated wheel stops are provided at the rear entry and the forward end, for either one way or two way entry/exit onto the platform.

Abstract: A rotary wheelchair lift comprising a hydraulic lift having a vertically telescoping slide tube and a horizontal wheelchair platform support arm attached to the lower end thereof. The arm supports a wheelchair platform having a front safety barrier, a rear entry ramp which folds up to become a rear wheel safety barrier, and a platform extension horizontally movable to accomodate wheelchairs of various sizes and types. A switch box and safety handrail assembly is mounted on the upper end of the slide tube. An UP/DOWN swtich causes the platform to be raised or lowered. An IN/OUT switch causes the platform to be rotated into or out of the van around a vertical axis offset from, but parallel to, the slide tube. A latching lever releases the handrail into a vertically downward position where it folds back the front safety barrier which interlocks the extension against horizontal motion preventing falls by able-bodied users traversing the platform.
