Title: Headrest stay
Inventor: MATSUMOTO SHINSUKE
IPC: B60N2/809
Filed: 2018-03-02
Abstract: To provide a headrest stay of which a strength is improved and weight saving is achieved.SOLUTION: One metallic pipe is bent into a substantially U shape. This headrest stay comprises a pair of legs, and a bridge part which connects upper ends of these legs to each other. A bent part is formed between these lags and the bridge part. A cross section of the bent part is an elliptical shape, and a long axis thereof extends in a cross direction of a seat.
