Child car seat buckles take a surprising amount of thumb force to release, a real barrier for parents and caregivers with arthritis, joint pain, or limited hand strength. This printed aid fits over the buckle and adds leverage so the release button can be pressed without straining a thumb.

The Child Car Seat Unbuckle Aid is part of WATAP’s free 3D-printed assistive technology catalog. Washington state residents can request a printed copy for free, and anyone can download and print their own from the links above.

A more ergonomic redesign is in progress; see the Ergonomic Child Car Seat Unbuckler v2 and v3 prototypes.
