Section 5 Backrest Strength Test – Static- Type I Test Procedure:
A force of 667N (150lbf) or 1001 N (225 lbf) shall be applied to the backrest at the backstop position for 0ne minute. Angle 70 ± 10 degrees, If the backrest/tilt lock mechanism will not accept the load due to gradual silpping of the adjustment mechanism during the load application, set the backrest to its most rearward(stopped) position, then apply the specified load(s). Remove the load
