Belt retractor for high class motor vehicle, has impact sound-insulating blocking mass coupling noise-damping acceleration sensor to retractor, where blocking mass has density higher than support element of acceleration sensor

摘要

The retractor (1) has an impact sound-insulating blocking mass (5) coupling a noise-damping acceleration sensor (2) to the retractor. The blocking mass has density higher than density of a support element (6) of the sensor, where the component rests against the blocking mass. The blocking mass is a part of a frame (7) that couples the sensor to the retractor. The sensor is arranged in a housing flap of the retractor, where the blocking mass is arranged between the housing flap and the sensor. The blocking mass has a mass amounts to 5 g, and is made of die-cast zinc or steel.
