3.4 front handlebar
frontally located bar provided for partially supporting the user’s weight with the user’s arm(s) and enhancing stability whilst exercising and to assist in emergency dismounts
EXAMPLE At low speed and high inclines.
3.5 side handrail
rail(s) located at the sides of the running surface provided for partially supporting the user’s weight with the user’s arm(s) and enhancing stability whilst exercising and to assist in emergency dismounts
3.6 foot rail
area beside the running surface intended for the user to stand on when mounting, dismounting or during a pause in the exercise
3.7 emergency dismount
act of the user quickly interrupting the exercise by getting off the running surface
Note ito entry: Emergency dismount can be done e.g. by grabbing the front handlebar or both side handrails and jumping with both feet on the foot rails.
3.8 heart rate control mode
programme that allows the user to train maintaining a predetermined pulse level by adjusting the speed and/or incline automatically according to the actual pulse of the user
3.9 display
device that provides information to the user
3.10 protective cover
cover provided to protect the user from inadvertent access to hazardous parts
EXAMPLE Moving parts, gear systems or hot surfaces.ISO 20957-6 pdf download.
