Abstract: A vehicle cab is described, which includes a plastic molded cab housing (16) that is securely held to a steel chassis (12), without concentrated stresses on the plastic housing that could damage it. The plastic cab housing (16) has vertical side walls (34) and a horizontally-extending flange (36) at the bottom. A metal frame (22) includes a beam that extends along the periphery of the housing and that lies under the plastic housing flange. A rubber spacer (24) has a top wall (42) lying over the housing flange, a bottom wall (44) sandwiched between the housing flange and the frame, and a connecting wall (48) connecting the top and bottom walls and lying beside the outer edge of the flange. A metal clamp (26) has a top part lying on the top of the spacer top wall, and a side clamp part that is fastened to the metal frame.

Abstract: A system is described for use in a truck cabin having a primary doorway (16, FIG. 2) at the rear of the cabin, which facilitates movement of the driver out of and into the driver's seat (20) when he leaves or enters by the rear doorway, by avoiding the restrictions of a steering wheel (26) that lies closely over the lap of the driver when he is driving. The system includes a mount (32) that supports the seat for rotation about a vertical axis, and an actuator (38, FIG. 4) connected to the mount to turn the seat between forward and sideward positions (20f, 20s) at which the seat respectively faces forwardly and largely sidewardly. A control coupled to the transmission (43, FIG. 2) of the vehicle, forcibly holds the seat in the forward position when the transmission is in a drive setting, to avoid unexpected turning of the seat while driving the vehicle.
