A pneumatically supported bunk assembly is dynamically leveled using compressed air provided by the vehicle. Level sensors determine deviation from the horizontal. Extension sensors associated with the pneumatic cylinders prevent over or under extension of the pneumatic cylinders.
Claims11
A bunk assembly for a vehicle comprising:
- a mattress platform;
- a plurality of vertically adjustable support pillars disposed to support the mattress platform from underneath, the plurality of vertically adjustable support pillars being independently adjustable;
- first and second level sensors mounted with respect to the mattress platform, one level sensor being associated with each one of two axes of a plane parallel to the mattress platform;
- and
- a mattress platform position controller being coupled to receive output signals from the first and second level sensors and being responsive thereto for providing independent control of the vertical extension of each of the plurality of vertically adjustable support pillars to maintain the mattress base in a horizontally level position.
