Force-Deflection Measurements of Cushioned Components of Seats for Off-Road Work Machines

HFTC4, Operator Seating and Ride
  • Ground Vehicle Standard
  • J1051_201308
  • Current
Published 2013-08-05 by SAE International in United States
This SAE Standard provides a method to obtain consistent force-deflection data of finished (or unfinished, when specified) cushioned components of seats for off-road work machines as listed in SAE J1116. This data may be helpful in maintaining seat comfort characteristics and quality control. There is no intent to establish any acceptance criteria.

Operator Restraint System for Off-Road Work Machines

HFTC4, Operator Seating and Ride
  • Ground Vehicle Standard
  • J386_201208
  • Current
Published 2012-08-24 by SAE International in United States
This SAE Standard establishes the minimum performance requirements for pelvic restraint systems (seat belts, anchorages, and the fastening elements of seat belts) necessary to restrain an operator or rider within a roll-over protective structure (ROPS) in the event of a machine roll-over, as defined in ISO 3471, or tip-over protection structure (TOPS), in the event of a machine tip over as defined in ISO 12117. This SAE Standard applies to off-road, self-propelled work machines fitted with ROPS as specified in ISO 3471, TOPS as specified in ISO 12117 and operator restraint.

Vibration Performance Evaluation of Operator Seats

HFTC4, Operator Seating and Ride
  • Ground Vehicle Standard
  • J1384_200711
  • Current
Published 2007-11-20 by SAE International in United States
This SAE Standard describes a procedure for the evaluation of operator seats which may be fitted to agricultural wheeled tractors per SAE J1150 and/or earthmoving machines per SAE J1057. This procedure evaluates only the vertical vibration performance and should not be considered a comprehensive seat evaluation procedure.
