System for providing adjustable occupant space in a vehicle

摘要

A system for varying space of a vehicle having a fixed portion with occupiable space and a number of ground engaging wheels coupled to the fixed portion. An expandable portion is coupled to the fixed portion and has a rigid floor. The expandable portion is movable relative to the fixed portion to adjust volume of a living space defined by the fixed and expandable portions. The floor is configured for planar movement along a generally horizontal plane when the expandable portion is moved. The system has a first load bearing arm engaging the floor to support the expandable portion. The first load bearing arm is pivotally anchored to the fixed portion to rotate about a generally vertical first axis to correspondingly move the expandable portion. Also, the system has an operator controlled actuator coupled to the first load bearing arm to selectively rotate the first load bearing arm and thereby control position of the expandable portion relative to the fixed portion to provide adjustment of the living space. The system may also include multiple swing arms controllably linked by a rod to facilitate tandem rotation.
