General




SIPS bag is activated with a specific side impact against the front door and then contributes to improved protection for the occupants of the front seats.
SIPS bag were introduced as standard on some markets and as an option on others, from model year 1995.

SIPS bag placed in the front seat
The SIPS bag consists of three main parts:
- 1. Sensor unit
- 2. Igniter cable
- 3. Cushion module

Note! The pictures in the service manual only show the left-hand front seat. The SIPS bag components for the right-hand seat are identical, with the exception of the pressure plate (in front of the sensor unit) which comes in right and left-hand designs.

Sensor unit




The sensor unit is positioned in a sensor bracket in the front SIPS pipe's outer end. Placement is the most protruding part of the seat against the inside of the door.
A pressure plate is mounted in front of the sensor unit. On side impact the pressure plate captures and distributes forces from the door's inner panel to the sensor unit.

Igniter cable
The igniter cable, which is of a pyrotechnical type, is routed in the back of the seat and under the seat cushion.
The igniter cable consists of two hoses that are coated with a pyrotechnical material on the inside. On detonation the signal is effected as a detonation wave.
The outside of the hoses are coated with a common, black protective sheath, which protects the hoses against mechanical damage.

SIPS bag cushion module




The cushion module is placed on the backrest frame to contribute to protect where the driver's/passenger's chest is closest to the door's inner panel.

Cushion
The cushion, which is manufactured of silicone coated polyamide fabric , is folded under a cover. When inflated the cushion has a volume of approximately 12 liters.

Gas generators
Two gas generators are used to inflate the cushion. On activation the gas generators produce a harmless gas that inflates the cushion very quickly.
