Abstract
A safety device in conjunction with a tensioning mechanism or a force-limiting device of a safety belt system of motor vehicles. The safety device includes a signal device for indicating actuation of the tensioning mechanism or force-limiting device, and after actuation, a signal device extends into a path of movement of a functional component of the safety device so that upon subsequent operation of the safety device, the signal device generates an audible signal.
Claims3
A safety device in the form of a self-blocking belt roll-up mechanism having a blocking mechanism that is adapted to be activated by vehicle-sensitive and/or safety belt-sensitive means, said roll-up mechanism being provided with a force-limiting means for limiting belt withdrawal, said force-limiting means becoming effective, in the event that the roll-up mechanism is blocked, via a belt withdrawal force that, in a belt unwinding direction, acts on an associated safety belt shaft, said safety device further comprising:
- signal means that is released by said limited belt withdrawal in said belt unwinding direction, wherein upon further rotation of said shaft, said signal means generates an audible signal.
