Seating Recs. |
 | | If the seat is higher than this (e.g., to increase the eye height for better visibility), the ill effects may be mitigated by shortening the seat and rounding off its front edge to reduce the under-thigh pressure. |
 | | A passive (molded seat pan) or active (seat belt) occupant restraint system should also be incorporated into the seat-workstation to prevent the operator from being thrown out of the seat during a turn, hard bump, or collision. |
 | | All seat adjustment levers, knobs, or buttons should be within hand's reach by 5th-percentile female and 95th-percentile male operators, should not block ingress or egress, and should not pose impact hazards in the event that unexpected machine motions throw the operator from the seat. |
