Abstract: A cabin purification system for a vehicle includes an air inlet in communication with a fan, a light source emitting ultraviolet C light at a wavelength of from 100 nanometers to 280 nanometers, a photocatalytic oxidizer element, and an air outlet. The photocatalytic oxidizer element has a surface coating comprising anatase and rutile forms of TiO2. The surface coating is illuminated by the light source. The fan generates an air flow from outside the air inlet to the air outlet. The air flow passes the light source and the photocatalytic oxidizer where the surface coating converts H2O O3 and O2 in the air flow into H2O2 which is distributed into the vehicle cabin to purify it.

Abstract: A tailgate can include first and second frames, doors and sets of touchpads. The frames can be coupled to the vehicle to selectively pivot about a first axis, and can be selectively coupled to the vehicle via respective frame latches. The doors can be coupled to the respective frames to selectively pivot about a second axis perpendicular to the first axis and relative to the frames, and can be selectively coupled to the frames via respective door latches. The sets of touchpads can be operably connected with the respective doors and frame and door latches. Actuation of one or both sets of touchpads in different configurations can facilitate opening one or both of the doors independent of or with each other in a first configuration pivoting about the first axis with the respective frames, or in a second configuration pivoting about the second axis relative to the respective frames.
