Abstract:
1. A fluid-filled elastomeric bladder assembly adapted for disposition in a vehicle seat intermediate an occupant load bearing seat cushion and an underlying spring suspension structure for occupant weight estimation, said fluid-filled elastomeric bladder assembly comprising: upper and lower interface panels formed of relatively thick rigid material for occupant load distribution; a sheet of relatively thin elastomeric material disposed between said upper and lower interface panels and peripherally joined to one of said interface panels to form a closed bladder and defining a volume therebetween for filling with a fluid, said sheet of thin elastomeric material and the interface panel to which it is peripherally joined forming upper and lower load bearing surfaces; and a port extending through said bladder and adapted for establishing fluid communication between said bladder volume and a fluid pressure sensor.
