VIBRATION ATTENUATOR SEAT Abstract of the Disclosure A vibration attenuator seat includes a seat assembly with a pair of paralleled shafts slidable in horizontally positioned, ultra low friction, linear bearings mounted in a base assembly. A seat adjustment assembly has a bottom part which is a part of the base assembly and a latch in its top part for engaging the bottom part to lock the top and bottom parts in a plurality of positions. A pin secured to the top part of the assembly centers the seat assembly relative to the top part by being connected by one preloaded, closed-coil spring to one end of the seat assembly and by a second preloaded, closed-coil spring to the other end. The body of a shock absorber positioned parallel to the shafts is secured to the pin and the rod is secured to the seat assembly. The latch allows positioning adjustment of the seat assembly relative to the base assembly and the shock absorber attenuates shocks and vibrations between the base and seat assemblies while the springs provide preloaded biasing towards the adjusted posi- tion.
