Patent Images
1. A seat belt tension-sensing device, comprising:
- a housing configured to be operably coupled to a portion of a seat belt webbing and to receive the seat belt webbing therethrough; and
a tension sensor mounted to the housing, the tension sensor having a deflectable substrate that is disposed adjacent a portion of the seat belt webbing, the deflectable substrate configured to be displaced by the portion of the seat belt webbing relative to the housing in response to tension being applied to the seat belt webbing, the tension sensor being configured to generate a signal in response to displacement of the flexible substrate that is indicative of an amount of tension being applied to the seat belt webbing.

8. A method of determining an amount of tension being applied to a seat belt webbing utilizing a seat belt tension-sensing device, the seat belt tension-sensing device having a housing and a tension sensor, the housing being configured to be operably coupled to a portion of the seat belt webbing so as to receive the belt webbing therethrough, the tension sensor being mounted to the housing and having a flexible substrate disposed against a portion of the seat belt webbing, the method comprising:
-
applying tension to the seat belt webbing such that the flexible substrate of the tension sensor is displaced relative to the housing; and generating a signal from the tension sensor in response to the flexible substrate being displaced, the signal being indicative of an amount of tension being applied to the seat belt webbing. - View Dependent Claims (9)
