Abstract

A lap belt take-up shaft for a seat belt retractor is arranged horizontally and substantially orthogonally to the traveling direction of a vehicle, whereby damage to the lap belt due to the drawing-out and rolling-in thereof is prevented and whereby a Vehicle Inertia Sensitive type emergency engagement device can be installed so as to demonstrate its function perfectly.

Claims

1. A seat belt system comprising:

a lap belt;

a lap belt take-up device, said device including a vehicular speed-sensing type emergency lock retractor having a belt winding shaft mounted on a car body frame member horizontally and substantially orthogonal to the traveling direction of the vehicle, one end of said lap belt being connected to said shaft;
