Abstract: An opening structure includes a lower door having an upper end configured to be rotated and opened with respect to a lower surface of a vehicle body, a garnish unit located on a surface of the lower door, at least a portion of a lower end of the garnish unit configured to be tilted from the lower door, a driving unit extending in a longitudinal direction and configured to apply driving force to the lower door and the garnish unit, a first driver configured to tilt the garnish unit, a second driver configured to integrally pop up the tilted garnish unit and the lower door and to apply opening force thereto, and a hinge arm connecting the first driver and the second driver to each other.

Abstract: A garnish structure includes a garnish unit configured to be located on a surface of a lower door and to perform impact absorption and load support, wherein the garnish unit includes a first layer region configured to absorb energy, and a second layer region configured to withstand a collision. The garnish unit further includes a garnish panel forming an outer surface of the garnish unit, a first impact member formed inside the garnish panel, an absorbing member located in the first layer region, a spring member located inside the absorbing member, a second impact member formed inside the first impact member, and a damping spring located in the second layer region.

Abstract: A bidirectional door opening structure includes a first door configured to be opened by rotating about a first end of a vehicle that is adjacent to a roof of the vehicle, a second door configured to be opened by rotating about a second end of the vehicle that is adjacent to the roof of the vehicle, the second end being opposite the first end, a drive unit disposed at a portion of the roof between the first door and the second door, and a controller configured to receive a door drive request with respect to the first door or the second door and to apply a driving force to at least one of the first door or the second door, wherein the drive unit comprises a spindle unit, a latching lever, and a rotation lever.

Abstract: A boarding/deboarding support structure includes a lower door having an upper end configured to be rotated and opened with respect to a bottom surface of a vehicle body, a lower trim located inside the lower door, the lower trim having an upper end configured to be rotated and opened with respect to a floor of the vehicle body, and an absorbing member having at least a portion supported by the lower door and a rear surface of the lower trim, the absorbing member being configured to absorb energy, wherein the lower trim is located between the floor of the vehicle body and an inner surface of the lower door, and wherein, when the lower door is opened, the absorbing member is deployed to be located between the lower trim and the lower door.
