This harness comes in three sizes. The small harness is used with the vehicle’s anchorage point (up to 36 kg). The harnesses are designed to be fitted to the person before entering the vehicle. Each harness requires the lap-sash seatbelt to be converted (using a gated-buckle) to a lap belt.
There is an optional pen-popper buckle (anti-escape feature) and anti-submarining strap.
