A barrier door for a protective enclosure includes a lower section and an upper section operably coupled with the lower section, and a ventilation system disposed within the lower section. The ventilation system includes one or more blowers and a plenum. The ventilation system is configured to direct air one or more of into or out of the protective enclosure.

A door opening and closing apparatus includes: a body defining an opening and an interior space, the opening being open toward the outside of a vehicle body and the interior space defined inside the vehicle body so as to be connected to the opening; a door configured to open and close the opening; a guide part disposed in the interior space and guiding the door such that the door moves in a first direction and a direction opposite to the first direction, the first direction being a direction from the outside of the vehicle body to the inside of the vehicle body; and a transport part disposed in the interior space and that moves the door in a second direction and a direction opposite to the second direction.

A completely transparent spherical body is surrounded externally by a plurality of leaf plates arranged in equal spacing along a main outer ring rack of the spherical body. Two rubber tires are included to wrap the spherical body. A rider inside the spherical body pedals to rotate the spherical body forward. A vehicle having the spherical body can be autonomously operated to move on land or water, and in the air. In addition, to operate this vehicle, no specific road or environmental requirement is needed, and no other obstacle, even a traffic accident can stop its movement.

One example embodiment is an armored vehicle door quick-release mechanism includes a handle, a slide lock latch, and an actuator mechanism. The handle is coupled to the slide lock latch. The movement of the handle in a first direction causes the slide lock latch to move in a first direction to a first position so that the slide lock latch is adapted to attach the vehicle door to the actuator mechanism adapted to open and close the vehicle door. A movement of the handle in a second direction causes that slide lock latch to move in a second direction to a second position to detach the vehicle door from the actuator mechanism.

An assembly for a vehicle includes a front pillar and a rear pillar spaced along a vehicle-longitudinal axis. The front pillar and the rear pillar define a door opening. The assembly includes a first track supported by the front pillar and a second track supported by the rear pillar. The assembly includes a lower bar and an upper bar movable upwardly relative to the lower bar along the first track and the second track. The upper bar is movable between a lowered position and a raised position. The assembly includes a crossmember pivotally coupled to the lower bar and the upper bar.

A connection system for a house and a vehicle, may include a vehicle door provided in the vehicle to open or close a vehicle entrance through which a passenger enters or exits the vehicle and allowing an internal space of the vehicle to be exposed into the house when authenticated by the house; and a hatch provided in a house entrance on a side wall of the house to selectively couple the house entrance and the vehicle entrance with each other so that an internal space of the vehicle and an internal space of the house are connected to each other in a state that the vehicle door is open when the authenticated vehicle is parked on a side of the house entrance.

A restraint system operating method includes, among other things, when a detachable door is attached to a vehicle, operating a restraint system of a vehicle at least in part in response to a signal from a door sensor of the detachable door. When the detachable door is detached from the vehicle, the method operates the restraint system of the vehicle without relying on the signal from the door sensor.

A stowable check strap assembly for a vehicle having a body and a removable door. The assembly includes a bracket configured to rotatably couple to the vehicle body, and a check strap rotatably coupled to the bracket and configured to be operably and removably coupled with a door detent coupled to the removable door. The bracket is rotatable between a deployed position where the check strap is positioned to extend outwardly from the vehicle body and engage the door detent, and a stowed position where the check strap is positioned to be and is rotated toward the vehicle body for stowage thereof.

A utility task vehicle includes a vehicle body including an opening. A door is positioned adjacent the opening. The door is configured to pivot about a first axis between an open position and a closed position. A window assembly is positioned adjacent and operably coupled to the door. The window assembly is configured to pivot about a second axis between an open position and a closed position. Rotation of the window assembly about the second axis is driven by rotation of said door about the first axis. In combination, the door and the window assembly substantially seal the opening of the vehicle body.

This invention is directed to a removable insulation curtain for a vehicle. The removable insulation curtain is made of a multi-layered flexible cover and can be used to cover openings in the vehicle, such as side and rear doors. The curtain is secured to the vehicle with removable fasteners around the perimeter of the door openings. The removable insulation curtain has a slot for people to enter and exit the vehicles without taking the curtain off and a window to let in outside light. The slot of removable insulation curtain enables side and rear doors of a vehicle to be used for ingress and egress while the tight fitment around vehicle doors reduces fluctuation of interior temperature relative to ambient temperature.
