Episode notes
Mom Solves The Puffy Coat Car Seat Problem
- Dahlia struggled each winter wrestling three kids out of puffy coats to buckle them safely in car seats.
- She sketched a side-opening coat, built a prototype with a Boston tailor, and had it crash-tested to let harnesses sit against the child without removing the coat.
Puffy Coats Create Hidden Car Seat Danger
- Puffy coats add up to about four inches of compressible bulk that can let a harness slacken in a crash.
- That compressed air reduces restraint effectiveness, meaning seemingly warm choices can create a real safety hazard.
Side Opening Coat Prototype Demonstration
- Dahlia prototyped a side-opening coat that flips the front panel to expose the harness area.
- The design lets parents buckle the harness against the child's chest, then close the coat over the strapped child for warmth.
