ABSTRACT:
A vehicle cab structure design providing air circulation through the cab compartment wherein the rear wall of the cab structure forms air flow passage defining a portion of the air flow circulation path. Suitable apparatus for controlling the temperature of the circulated air may be provided. The circulation may be effected by a suitable air moving device, such as a fan, which may be associated with the temperature controlling apparatus. In the illustrated embodiment, a forced air fan is utilized for effecting the desired circulation of the cab air. A fresh air inlet may be provided for introducing a preselected amount of fresh air into the circulating air. A filter may be provided for filtering the circulated air. The filter may be arranged to filter the incoming fresh air also. The filter may be arranged horizontally to permit self-cleaning with the debris therefrom being collected on a subjacent duct wall. The rear wall structure may form a structural support portion of the cab suitable to support the top wall of the cab.
