Abstract

A cabin system to be mounted on a vehicle body includes a driver'"'"'s seat, an air conditioner body for indoor air conditioning disposed downwardly of the drive'"'"'s seat, a plurality of support pillars constituting a cabin framework, a ceiling portion, and a main duct having a hollow tubular construction, the main duct forming therein an air passageway for the indoor air conditioning. The main duct includes, at a lower portion thereof, a duct connecting opening to be connected to the air conditioner body and also includes, at a lateral portion thereof, a support pillar engaging face. The main duct is attached through the support pillar engaging face to one of the support pillars along an indoor side peripheral face of the one support pillar. The support pillar engaging face of the main duct and the indoor side peripheral face of the one support pillar have profiles complementary with each other.

Claims

1. A cabin system to be mounted on a fore/aft elongated vehicle body, the cabin system comprising:

a pair of right/left front support pillars;

a pair of right/left rear support pillars;

a front upper beam joining upper portions of the pair of right/left front support pillars, the front upper beam being an angular pipe having an upper face, a bottom face, a front side face and a rear side face, each of the upper face and the bottom face being inclined forward and upward, wherein the front upper beam is curved in form of an arch such that a longitudinal center portion of the front upper beam is positioned forwardly of opposed ends of the front upper beam;

a rear upper beam joining upper portions of the pair of right/left rear support pillars; and

a driver'"'"'s seat provided within an inner space defined by the pair of right/left front support pillars, the pair of right/left rear support pillars, the front upper beam and the rear upper beam.

2. The cabin system according to claim 1, wherein

each of the pair of right/left front support pillars is profiled to have a first recess for receiving a right/left end of the front upper beam.

3. The cabin system according to claim 2, further comprising:

a side upper beam interconnecting the respective upper portions of the right/left front support pillar and the right/left rear support pillar;

wherein each of the pair of right/left front support pillars is profiled to have a second recess for receiving a front end of the side upper beam.
