Seat Occupant Sensor: Locations

Occupant Classification Sensor (OCS) Components:

Index
1. Topper Board: Provide stable and smooth reaction surface for Bladder,together with Felt Pad.

2. Bladder: Sense occupant weight and provide fluid pressure input to Pressure Sensor.

3. Push pins: Use to secure the Bladder assembly on the seat pan and maintain the correct Bladder position during seat assembly.

4. Backer Board: Provide stable and smooth reaction surface for Bladder, together with Felt Pad.

5. Felt Pad: Provide stable reaction surface for Bladder, together with Backer Board, and protect Bladder Assembly from the seat frame environment.

6. ECU: Utilizing data from the Pressure Sensor, BTS (Belt Tension sensor), and Compensation Tables, determine if PAB (Passenger Airbag) will be suppressed.

7. Pressure Sensor: Sense pressure input from Bladder and convert the pressure input to a voltage signal for ECU.
