A transport that is manually powered for transporting an injured or disabled person from one location to another. The chair is particularly useful for transporting an injured or disabled person (who is of a heavy weight) up or down a flight of stairs. The chair lift is manually driven by reciprocating hand levers operated by an attendant. A ratchet and pawl mechanism in combination with a brake system, which is continuously set / locked, allows movement of the chair only when the chair is being propelled up a flight of stairs and when an attendant purposefully actuates a hand lever to release the brakes and allow movement of the transporter.

A compact wheelchair lift mechanism utilizes a horizontal actuator to advance the vehicle doors outwardly away from the side of the vehicle together with a wheelchair user supported by a platform, and a vertical actuator which then lowers the platform with the wheelchair and user downwardly between the doors and vehicle. With the platform on the ground next to the vehicle, the user may then roll forward and away from the vehicle. The vehicle doors are also pivotably attached to the lift mechanism, such that a user may exit the vehicle by simply opening the vehicle door about its traditional door hinge, and therefore without powering the actuators. In this way, the wheel chair lift mechanism provides for safe and easy exit from the vehicle even if electrical power is lost, and facilitates use of the vehicle by both wheelchair-using drivers and drivers who do not use a wheelchair.

An automatic crossbar on a ski chair-lift for containing seated passengers and facilitating dismounting passengers. A vertically elongated bar (20) with a cross (20a) attached at its base is pivotably suspended from a passenger chair, positioning the crossbar in front of passengers. An elastic closure attachment (9), and / or an automatic locking mechanism (60), is attached between the elongated bar and the chair to retain the crossbar in a closed position and contain passengers. A blocking structure (200) is suspended proximal to the aerial cable above the landing platform. The elongated bar has an upper portion (20v) above its pivotal mount (21b) which impacts the blocking structure as the aerial cable moves the chair forward. The impact causes the upper portion to rotate back as the lower portion and crossbar are levered forward and upward. As the crossbar swings forward from the chair, passengers grasp the crossbar to balance with while standing onto the landing platform.

A wheel chair lift device includes a lift car selectively elevated above a base, along with protective skirting covering the region below the lift car. Exposed portions of the protective skirting subject to lateral inward deformation are provided with skirt deformation sensors for detecting abnormal inward deformation of such skirt portions. The skirt deformation sensors include a spring or other elongated deformable member that extends generally parallel and proximate to the portion of the skirt being sensed. A sensor detects that the elongated member has been laterally displaced from its usual longitudinal axis and generates an electrical signal. In response to such electrical signal, the lift device stops further movement of the lift car.
