A vehicle cab has an airflow deflector (9) pivotally mounted on it for movement between a lowered position and a raised position in which the deflector is inclined upwardly and rearwardly from a front upper portion of the cab, and the deflector has, or is associated with, side and rear walls which together with the deflector define a compartment above the cab when the deflector is in a raised position. Access can be gained into the compartment from inside the cab. A bunk (11) can be provided in the compartment for a person to sleep in the compartment. Seats in the cab have back rests (4) which fold down on to the seats, or can be removed, so that a bunk, which is stowed at the back of the seats when not in use, can also be erected in the cab over the seats. In one embodiment the deflector (9) is pivoted to a frame (8) mounted around the top of the cab, and the side and rear walls are provided by a cover (26) of flexible material which is secured to the deflector, frame and cab roof structure and folds in concertina fashion when the deflector is lowered. In another embodiment the deflector is formed by an upper part of a pod mounted on the cab, the upper part being hinged to a lower part to enable the deflector to be pivoted between raised and lowered positions. The upper part may be raised at the front relative to the lower part to increase the capacity of the compartment formed by the interior of the pod.
A vehicle cab in which is a driver's seat and which has an airflow deflector on a roof thereof of generally plate form extending over substantially the same width as the cab, pivotal connecting means between said deflector adjacent a front edge thereof and a front upper portion of the cab whereby said deflector can be swung about a horizontal axis between raised and lowered positions relative to the cab, side walls and a rear wall extensibly connected between said deflector and the cab, means for swinging said deflector upwardly about said pivotal connecting means and means to retain said deflector in a raised position at which said deflector and said side and rear walls define a compartment above the cab, an opening in the roof of the cab providing access to said compartment from the cab, and a bunk extending transversely of the cab in an elevated position within the envelope defined by the cab and said compartment and substantially directly above said driver's seat, said bunk being accessible by way of said opening when said deflector is in a raised position.
