Abstract: A cooling system for a variable frequency drive (VFD) of a transport refrigeration unit (TRU) is disclosed. The system comprises a conduit disposed within the vehicle and extending between a opening provided at a first predefined position on the outer body of the vehicle and the VFD being positioned at a second predefined position within the vehicle. The opening facilitates the inflow of ambient air within the conduit that carries the ambient air towards the VFD to enable cooling of the VFD. The system includes a grill cover adapted to be removably attached to the opening and/or the first end of the conduit, which allows entry of the ambient air within the conduit and restricts entry of outside objects and/or living organisms within the conduit.

Abstract: A seating support includes a lumbar support portion having first and second lumbar supports. The lumbar support portion defines at least a portion of a channel extending between the first and second lumbar supports. The channel is sized to substantially preclude contact with an occupant of the seating support. Such a seating support also includes a coccyx support portion having first and second coccyx supports. The coccyx support portion is disposed substantially perpendicular to the lumbar support portion and is in communication therewith such that the channel extends from the lumbar support portion between the first and second coccyx supports.
