Folding push-chair back-rest inclination adjusting device, has belts inserted into holding block, exerting pressure so that tooth surfaces are pressed together to secure belts

摘要

Diverging belt (4) sections exert pressure on a pivotable holding block (a), so that tooth surfaces are pressed together to prevent the belts being pulled through the adjusting device. When finger surfaces are pressed, the tooth surfaces are moved apart, allowing the length of the belt to be adjusted.
