couvre-chef

Ce casque «antichute» ou «Bolli», selon le vieux terme en dialecte bâlois, est un couvre-chef que les enfants qui apprenaient à marcher portaient en cas de chute.

A helmet like this one worn by a toddler learning to walk would normally be called a Fallhaube – which translates literally as “crash helmet” – or Bolli, to use the old dialect word.
