Load limiter for strain gauge occupant classification sensor
First Claim
1. An over-travel protection device comprising:
- a first seat mounting portion;
a second seat mounting portion spaced apart from said first seat mounting portion;
an occupant classification sensor having a pair of deflecting members mounted to said second seat mounting portion, said occupant classification sensor having an upper surface and a lower surface;
a sensor plate attached to said lower surface of said occupant classification sensor;
a spacer having a land mounted to said first seat mounting portion, said spacer being positioned adjacent to said upper surface of said occupant classification sensor; and
a compliant element located between said occupant classification sensor and said second seat mounting portion, said land being spaced from said second mounting portion until said deflecting members and said compliant element deflect a predetermined amount, causing the land to abut said second seat mounting portion and thereby preventing further displacement of the deflecting members and compliant element.

Abstract
An over-travel protection device for mounting an occupant classification sensor having a deflecting member, the sensor being mounted between first and second seat mounting portions, is described. The device has a sensor plate positioned adjacent the occupant classification sensor and a spacer having a land. The spacer is positioned adjacent to the occupant classification sensor. A compliant element is located between the sensor plate and the second seat mounting portion. The land is spaced from the first mounting portion until the deflecting member deflects a predetermined amount, causing the land to abut the first seat mounting portion and thereby preventing further displacement of the deflecting member.

7. An over-travel protection device, comprising:
-
a seat rail; a seat riser separated from said seat rail; an occupant classification sensor including a pair of deflecting members mounted to a side of said seat riser opposite said seat rail, said occupant classification sensor mounted to said seat riser via a pair of fasteners attached to said seat riser via a pair of deflectable grommets; a sensor plate mounted to said occupant classification sensor on a side of said occupant classification sensor opposite said seat riser; a spacer having a land mounted between said seat rail and said seat riser; and a washer disposed between said occupant classification sensor and said seat riser, wherein upon deflection of said deflecting members and said deflectable grommets in a first direction, said land will abut said seat riser, and upon deflection of said deflecting members and said deflectable grommets in a second direction, said washer will abut said seat riser. - View Dependent Claims (8, 9, 10, 11, 12)
