Title: Seat belt mechanism
IPC: B60R22/185
Filed: 1980-09-04
Abstract: A seat belt for a vehicle passes over a roller 1 rotatably mounted within a housing which swivels on vehicle structure such as a door post. A sensing unit mounted above the housing includes a circular pendular mass 17. The mass is supported by a stalk having a part spherical upper end 15 carried in a vertical tubular guide 14. The mass sits on an inverted cone 18 located within an oppositely tapered recess in the under part of the mass, the tip of the cone seating in a "dimple" in the housing. Displacement of the mass as by acceleration due to impact of the vehicle causes it to rock about the upper edge of the cone which will raise the stalk upper end in the tubular guide. This in turn lifts a rod 21 connected to a pivoted quadrant 22 to trap the belt by engagement with serrations 24 in the quadrant surface pressing it into contact with a surface of the housing 4. <IMAGE>
