Division Hazards associated with moving parts

Once the chair-mounted seat is set up for normal use, there must not be any accessible compression or shear points as a result of moving the chair-mounted seat or any part of it, the child’s shifting its body weight while in the chair-mounted seat, or the application of an external force (either by another child or, unintentionally, by the carer, or by a powered mechanism).

Chair-mounted seats designed to fold must have a folding mechanism that a child cannot operate and that a carer cannot inadvertently trigger. It must not be possible to set up chair-mounted seats for normal use without activating the locking mechanism.
