Pneumatic operated fore/aft vibration isolator locking device

摘要

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.

1. 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, the vibration isolator component including:
a plurality of restrictor plates,a spring in communication with a plurality of restrictor plates; anda 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, andwherein a plurality of spacers are disposed between the plurality of restrictor plates,wherein when the pneumatic piston mechanism is not actuated, the spring is biased away from the plurality of restrictor plates such that the spring clamps the plurality of spacers to the plurality of restrictor plates thereby locking the restrictor plates.
