Deformable structure for a child safety seat

摘要

An energy-absorbing deformable structure 26 to secure a child seat 12 to a mounting portion 16 of a vehicle 14 comprises a metal wire coupled between the seat and the mounting portion. The wire is formed to fit within a space having a predetermined perimeter 32 and curves inwardly on itself from the perimeter in at least one location so that the circumference of the metal wire is longer than the length of the perimeter. The metal wire may be a loop of metal rod having a base end 20 configured to be coupled to the mounting portion, a distal end 22 configured to be coupled to the seat, and a plurality of sinuous deformable portions 30 positioned between the base end and the distal end. The sinuous deformable portions may be configured to be deformed when the base end and distal end are pulled in tension thereby absorbing energy. Also disclosed are an attachment assembly 10 comprising such a deformable structure and a motor vehicle comprising a child safety seat fastened to a mounting portion by such an attachment assembly.
