Vehicle occupant sensing system having a contamination barrier member
First Claim
1. A vehicle occupant sensing system for detecting a condition of a vehicle seat assembly having a seat cushion defining an upper surface and a lower surface disposed spaced from the upper surface, said vehicle occupant sensing system comprising:
- at least one sensor;
at least one sensor assembly disposed adjacent the lower surface of the seat cushion, said sensor assembly having a base and an upper slide member slidably attached to said base for movement toward and away from said base wherein said sensor is operable to detect movement of said upper slide member toward and away from said base in response to movement of the upper surface toward and away from the lower surface of the seat cushion; and
at least one contamination barrier member operatively attached to said upper slide member and at least partially shielding said sensor assembly to decrease contamination of said sensor assembly.

Abstract
A vehicle occupant sensing system that includes at least one sensor and at least one sensor assembly. The sensor assembly has a base and an upper slide member supported for movement toward and away from the base wherein the sensor is operable to detect movement of the upper slide member toward and away from the base. The vehicle occupant sensing system also includes at least one contamination barrier member operatively attached to the upper slide member and at least partially shielding the sensor assembly to decrease contamination of the sensor assembly. The vehicle occupant sensing system may be employed in a vehicle seat to detect a condition of the vehicle seat.
