SEAT BELT SYSTEM WITH BUCKLE LATCH AND TENSION SENSOR
First Claim
1. A seat belt buckle assembly configured for use in a vehicle seat belt system, wherein the assembly comprises:
- a magnet; and
a magnetic sensor configured to determine displacement of the magnet relative to the magnetic sensor, wherein the seat belt buckle assembly is configured to cause a first displacement in response to engagement of a seat belt tongue with the assembly and cause a second displacement in response to tension on a seat belt webbing, wherein the second displacement is distinct from the first displacement.

Abstract
A seat belt system configured for use in a vehicle includes a seat belt buckle assembly that is configured to determine the both the latch condition of the seat belt buckle assembly with the seat belt tongue, and the tension applied to the seat belt webbing in a seat belt system. The seat belt buckle assembly includes a latch configured to receive and engage the seat belt tongue, a magnet, and a magnetic sensor configured to determine relative displacement of the magnet. The seat belt buckle assembly is configured to cause a first displacement between the magnet and the magnetic sensor in response to engagement of the seat belt tongue with the latch and cause a second displacement between the magnet and the magnetic sensor in response to tension on the seat belt webbing via the seat belt tongue. The first displacement is distinct from the second displacement.
