Seat belt retraction device has energy absorbent cover attached to base with main body part covering sensor mechanism with elastically deformable arms for absorbing impact energy

摘要

The safety belt system has a base, a spool on the base able to rotate about an axis in a belt retraction direction and an opposite deployment direction, a long seat belt strap (16) wound on the spool to protect a vehicle occupant, a spool locking mechanism, a sensor mechanism on the base and a cover attached to the base with a main body part covering the sensor mechanism with a number of elastically deformable arms for absorbing impact energy.
