First Claim
Patent Images
1. A sensor assembly for use in a vehicle seat cushion for detecting the presence of an occupant, said assembly comprising:
- a first member defining an opening;
a second member having a portion slidably disposed in said opening such that said second member is movably mounted relative to said first member along a predetermined path;
a spring housed at least in part in said opening, said spring biasing said first member relative to said second member; and
a sensor device mounted to detect relative movement between said first and second members.

Abstract
A sensor assembly for use in a vehicle seat cushion for detecting the presence of an occupant includes a first member defining an internal bore. A second member has a portion slidably disposed in the bore of the first member. The first member is movably mounted relative to the first member about an axis. A spring biases the first member relative to the second member. A sensor device is mounted in one of the first and second members.
