The Thomashilfen tRide 4 Point Padded Hip Belt is designed to secure a child's hips onto the seat of the stroller more effectively than a 2 point belt. The extra contact points on the 4 point belt mean that when the belt is tightened, the securing force is directed towards the seat rather than the back corner where the seat and back meet. Especially important for children with high tone to prevent sliding forward on the seat. In German, Thomashilfen means "Thomas Helps".
