Seatbelt force sensor assembly with guide member
First Claim
1. A mounting assembly for a seatbelt tension sensor comprising:
- a rigid member having one end operably coupled to a seatbelt portion;
a sensor mounted on said rigid member for measuring strain exerted on said rigid member by an input force applied to the seatbelt portion; and
a bracket having a first mounting portion for attachment to said rigid member and a second mounting portion for attachment to a vehicle structure to define a guide for isolating said sensor from non-axial input forces applied to the seatbelt portion.

Abstract
A system for measuring seatbelt forces includes a guide that isolates a seatbelt force sensor 40 from input loads applied to the seatbelt at an angle. The system includes a rigid plate member 42 that supports the seatbelt force sensor 40, and which has one end attached to a portion of the seatbelt and an opposite end mounted to a guide bracket 70. The guide bracket 70 includes a pair of circular bosses 72 at one end for pivotally mounting the bracket 70 to a vehicle structure such as a B-pillar 68, for example. The bracket 70 guides the seatbelt in such a manner that input loads to the seatbelt that are applied at an angle do not affect the bending of the sensor 40.

11. A bracket for a seatbelt force sensor assembly comprising:
-
a generally flat body portion for supporting a seatbelt for sensor assembly, said body portion being defined by a first end, a second end, a first side interconnecting said first and second ends to define a first edge, and a second side interconnecting said first and second ends to define a second edge opposite from said first edge; and
a plurality of boss portions including at least a first boss portion extending outwardly along a portion of said first edge and a second boss portion extending outwardly along a portion of said second edge wherein said body portion and said boss portions define a guide. - View Dependent Claims (12, 13, 14, 15, 16, 18)

17. A method of measuring a seatbelt force comprising the steps of:
-
mounting a seatbelt force sensor to a rigid plate member;
mounting one end of the rigid plate member to a seatbelt portion;
mounting an opposite end of the rigid plate member to a vehicle structure;
applying an input force to the seatbelt portion;
guiding the seatbelt portion with a guide member to isolate the seatbelt force sensor from input forces applied at an angle; and
generating an output signal from the seatbelt force sensor representative of the force applied to the seatbelt portion.
