A boarding system for a vehicle for transporting people includes a retractable step that has a lifting function and a ramp function. An extendable front edge of the retractable step and a rear edge of the retractable step are arranged behind in the direction of travel and are adjustable in terms of height.

A height adjustable loading ramp installed at a tail of a car, for loading or unloading goods, includes: a slope plane and a supporter. The two ends of the slope plane are respectively supported on the ground and the supporter. The supporter includes: two supporting legs adjustable in length, a beam horizontally provided between lower portions of the two supporting legs, wheels for making the loading ramp move conveniently, and a scissor jack for adjusting the height. The scissor jack includes: four scissor jack arms equal in length, and an adjusting-locking device for adjusting and locking the height of the height adjustable loading ramp. In addition, the supporting leg comprises an auxiliary fixing unit for fixing the relative position between the upper and the lower supporting legs and providing an extra security protection, in such a manner that the height of the height adjustable loading ramp is locked.

A vehicle step device includes: a movable step that is provided in a door opening of a vehicle; and a drive controller that drives the movable step so that the movable step operates in deployment and storage directions. The drive controller includes a sidewalk detection unit that detects a sidewalk provided in parallel with a traveling road surface of the vehicle, a separation distance detecting unit that detects a separation distance between a side edge portion of the vehicle in which the movable step is stored and the sidewalk, and a deployment amount setting unit that sets a deployment amount of the movable step extending in a width direction of the traveling road surface from the side edge portion of the vehicle based on the separation distance. The deployment amount setting unit sets a deployment amount of the movable step to be larger as the separation distance increases.

A foldable ramp for wheelchair access to a passenger car door, can include an entry platform which can be arranged an entry positon where the ramp is folded out of the car to allow wheelchair access to the car, a transport position where the entry platform is arranged in the car in an upright position, and a passive position where the entry platform is arranged in the car in a lying positon. The ramp can include a pivoting mechanism to mount the platform to the car, and can include an interlock configured to allow movement of the platform relative to the car and fix the platform relative to at least a section of the car.

An operating mechanism for a ramp door includes a door actuation system and a limit stop system. The actuation system is connected between the door and a frame or the vehicular structure directly and is operable to pivot the door between closed, deck, and ramp positions. The limit stop system selectively limits the pivoting of the door to a range between the closed and deck portion or to a range between the closed and ramp positions.

An electric vehicle includes: a box-shaped base frame in which a battery is stored in an internal space, with a vehicle drive unit using an in-wheel motor attached to a side surface; and a floor panel that is separately arranged from the base frame at a position above the base frame in the vehicle. In the electric vehicle, a slope device that feeds out a slope board toward a sidewalk or a road is provided in a clearance between the base frame and the floor panel.

A tonneau cover for a vehicle has a topside and an underside. The tonneau cover also includes a rail system attached to the underside. The tonneau cover also includes a ramp system. The ramp system is slidably engaged with the rail system and is configured to slide out from the underside along the rail system such that a rear end of the ramp system engages a ground surface to create a rampway between the topside and the ground surface. The ramp system can be used to load large cargo onto the topside of the tonneau cover. The ramp system is also removable from the rail system and attachable to an end of a truck bed of the vehicle such that the ramp system can be used to load cargo into the truck bed.

An operating mechanism for a ramp door includes a door actuation system and a limit stop system. The actuation system is connected between the door and a frame or the vehicular structure directly and is operable to pivot the door between closed, deck, and ramp positions. The limit stop system selectively limits the pivoting of the door to a range between the closed and deck portion or to a range between the closed and ramp positions.
