摘要： A safety barrier for wheelchair lifts is disclosed, and more particularly a safety barrier assembly (10) which can be used singly or in opposed pairs to open automatically and mechanically in cafe-style, rotating 90° from a first closed or barrier position to a second, open, pass-through position. More particularly, these barriers may be used as barriers on wheelchair lift platforms (24) or at the door opening of a van or transit vehicles on which a wheelchair lift is mounted. The barriers (32) typically are shaped like the letter P with the lower most barrier member being spaced from twelve inches to two feet above the floor, and which are designed to prevent wheelchairs from rolling out of the van when the platform (24) has left the transfer level (vehicle floor), and as a safety barrier in the case of runaway wheelchair events. The preferred embodiment of the gate is mounted to a pivotal cam slot/bias spring assembly (14) which provides for stable open and shut positions with spring/gravity assisted closure. The preferred embodiment also includes a safety interlock switch circuit which prevents lift platform motion when the gate barrier is open.

摘要： The present invention incorporates a fluid pressure sensing switch (18) in fluid communication with a hydraulic fluid outlet (12) of a hydraulic pump (10) driving a platform lift (4). The pressure switch is calibrated to activate at a pump outlet pressure created when the pump attempts to fold the platform into the stow position when it carries a load. The switch is calibrated not to activate at a pump outlet pressure created when the pump attempts to fold the platform into the stow position when the platform is unloaded. Activation of the pressure switch disables the hydraulic pump, thereby preventing a loaded platform from being folded into the stow position.

摘要： A vehicle access system for moving a passenger between the vehicle and ground. Some embodiments have an electrical system, a motive source (12) coupled to the electrical system, an arm (14) coupled to the motive source (12), a platform (22) coupled to the arm (14), and a safety restraint system (202) coupled to the electrical system and the platform (22). The vehicle access system has at least a vehicle access position and a ground access position, wherein the passenger can safely access the platform (22) at either access position. The platform (22) is unable to move from either access position until the safety restraint system (202) is in place. Once operation of the access system has begun, it can continue to operate and move the passenger to one of the access positions even if the safety restraint system (202) is subsequently removed.
