Seat suspension for underground mining machines

摘要

A compact seat suspension for an underground mining machine is disclosed in which a vertical suspension is operably connected between a fixed bracket and a sliding bracket for supporting a seat and for reducing and dampening vibration and shock transmitted from the mining machine to the seat. The fixed bracket is attached to a side wall of the mining machine and includes one or more vertical guide members. The sliding bracket is movably mounted on the vertical guide members for relative vertical movement with respect to the fixed bracket. The sliding bracket is attached to the back portion of a seat provided within the mining machine. The entire compact assembly is adapted to be positioned entirely behind rather than beneath the seat, making it possible to utilize the suspension in areas of reduced height. The fixed bracket may be adjustably attached to the mining machine by a pair of hanger members which include recesses adapted to receive and retain pins which extend outwardly from opposite edges of the fixed bracket.
