Abstract:
A passenger occupancy detection system and method are provided for detecting occupancy of a vehicle seat. The system includes a pressure sensor for monitoring pressure of the seat. Routines are employed to monitor the pressure and to determine the occupancy of the seat based upon one or more of vehicle acceleration, vehicle deceleration and variances in inertia experienced during driving of the vehicle. A supervisory routine may combine outputs from the multiple routines to process the outputs and provide an output indicative of a detected occupancy of the seat.
Abstract:
A mounting anchor for a motor vehicle includes a locking bar, a first switch, a first movable plate, a second switch and a second movable plate. The first switch is positioned adjacent a first side of the locking bar and the first movable plate is positioned to slidably engage a groove on the first side of the locking bar. The first movable plate includes a first activation area for receiving a portion of the first switch and a first aperture for receiving a first rotatable arm. The second switch is positioned adjacent a second side of the locking bar, which is opposite the first side of the locking bar. The second movable plate is positioned to slidably engage a groove on the second side of the locking bar and includes a second activation area for receiving a portion of the second switch and a second aperture for receiving a second rotatable arm.
Abstract:
A seat bladder weight estimation apparatus includes an interface panel having multiple regions of substantial rigidity separated by regions of insubstantial rigidity. The regions of substantial rigidity limit sensitivity to seat foam variations, and the regions of insubstantial rigidity permit differential movement and angulation of the rigid regions for regional transfer of occupant weight to the bladder. The regional transfer of occupant weight to the bladder allows regional variation of the bladder sensitivity to occupant weight through various bladder geometry design features.
