Side Impact Protection System: Description and Operation
General Information
The SIPS bag is activated by certain side impact collisions and is designed to help increase protection to front seat passengers.
The SIPS bag is being introduced as standard equipment in some markets and as an option in others, beginning with model year 1995.
SIPS bag installed in front seat
The SIPS.bag system consists of three main components:
1. Sensor unit
2. Firing circuit
3. Cushion module
NOTE: Illustrations in service manual show left front seat. SIPS-bag components for right front seat are identical, except that the pressure plate (at
the front of the sensor unit) is specific to left or right side.
Sensor unit
The sensor unit is located in a sensor mount at the outer end of the forward SIPS tube. The mount is the part of the chair that protrudes the most
toward the inside of the door.
A pressure plate is mounted forward of the sensor unit. In the event of a collision, the pressure plate transfers the force from the inside door panel to
the sensor unit.
Firing circuit
The pyrotechnic firing circuit runs through the seat back and under the seat cushion.
The firing circuit consists of two tubes coated on the inside with a pyrotechnic material. When triggered, the signal is transmitted as a shock wave.
The tubes are covered with a black protective sleeve to protect them from mechanical damage.
