Abstract
Abstract A safety seat belt system for use in a vehicle in which an upper end section of its webbing is made narrower to allow the use of a compact retractor that can be placed in the center pillar of the vehicle. In order to prevent the narrower upper section to be extended over the torso of the occupant when worn by the occupant and to safely restrain the torso by the remaining broader webbing section, at least two guide members are provided to guide the webbing between the retractor and relevant shoulder of the occupant. Owing to the compact structure of the retractor, it is suitable particularly for small cars.
