Abstract
A multi-directional vibration attenuator seat is capable of limited, restrained movement in any direction within a generally horizontal plane in response to vibration and other motions of the seat and the vehicle in which the seat is mounted. The limited movement is made possible by a seat arrangement in which an intermediate assembly is disposed on top of and slidable relative to a base assembly along a first axis with a seat supporting upper assembly being disposed on and slidable relative to the intermediate assembly along a second axis extending in a direction generally perpendicular to the direction of the first axis. The seat is normally maintained in and is restrained from movement out of a nominal position relative to the base assembly by a plurality of springs. A pair of shock absorbers disposed generally perpendicular to each other damp movement of the seat along the first and second axes respectively. An adjuster latch and lever arrangement is used to position the base assembly at a selected location along a pair of slidable adjusters on which the base assembly is mounted. Attenuating movement of the seat can be locked out by a manually controlled lever which drops a pin…
