Abstract
A pneumatic fore-aft vibration isolator lock system (and method) is provided. The innovation provides a locking action through the use of pneumatically-actuated spring pressure to lock or unlock the isolation system. In one aspect, to unlock, air pressure is applied and the spring pressure is overridden by the air pressure. By overriding the spring pressure, plates are moved thereby unlocking the isolator. The system can allow for one touch, fingertip locking and unlocking of the fore/aft isolation system.
Claims20
A vibration isolation system for a seat assembly comprising:
- an air supply component;
- a vibration isolator component that receives air from the air supply component and locks or unlocks a vibration isolation device based upon an amount of air pressure.
A vibration isolation lock device for a seat assembly comprising:
- a plurality of restrictor plates;
- a spring in communication with the plurality of restrictor plates;
- and
- a pneumatic piston mechanism communicating with the spring,
- wherein the plurality of restrictor plates restricts movement of a movable seat frame with respect to a fixed seat frame based on an amount of air pressure from the piston mechanism.
A method of pneumatically operating a vibration isolator for a seat assembly comprising:
- providing pneumatic pressure to a piston mechanism;
- moving a piston in the piston mechanism as a function of the pneumatic pressure;
- compressing a spring based upon the act of moving the piston;
- and
- releasing a restrictor plate, wherein the release of the restrictor plate unlocks the isolator thereby enabling fore-aft vibration isolation to the seat assembly.
