Securing device for locking inclination=adjustable back rest of road vehicle seat

摘要

One link part is connected to the seat and the other to the back rest and through the two parts runs a horizontal pivot axis. This pivot axis (8) is non-rotatably located and has a threaded section (14), on which a disc-shaped, eccentric fly weight (15) is fitted with a corresponding inner thread. The fly weight at normal acceleration values is held in position by a spring (19). On one or both sides, a pressure plate (20) is arranged axially displaceably on the pivot axis, which on its side facing the fly weight is provided with spaced apart projections (21), which engage through the link part (6) between the fly weight and the pressure plate.
