Toyota RAV4>> Electric equipment>> Safety cushions



All models are equipped with an auxiliary security system (SRS — Supplemental Restrain System) better known as safety cushions. The system consists of the sensors of blow installed from the forward party of the car, safety cushions and the control unit and diagnostics located about the central console.
During collision the pyrotechnic gas generator inflates a safety cushion the emergency explosive process, providing full filling before contact with the driver or the forward passenger. Then the safety cushion reacts to contact with the driver or the forward passenger partial reduction of pressure of the operation calculated according to physiologically acceptable pressure and by the braking forces operating on the driver or the forward passenger. It is as a result warned or considerably the probability and weight of wounds of the head and thorax decreases.
The safety cushion of the driver is established in the center of a steering wheel. For signal transmission from the control unit to a safety cushion the spiral wire established on a steering column is used. The spiral wire transmits a signal irrespective of the provision of a steering wheel. The pyrotechnic gas generator will transform the operating electric signal to an arson signal therefore powder decays, inflating a safety cushion bag.

Fig. 15.65. A safety cushion of the forward passenger on models since 2001: 1 – safety cushion of the forward passenger; 2 – electric socket of a safety cushion of the forward passenger; 3 – ware box


The safety cushion of the forward passenger is established over a ware box and closed by a decorative cover (fig. 15.64, 15.65) . Safety cushion volume considerably bigger, than volume of a safety cushion of the driver. The decorative cover is painted in color of the dashboard and has a seam which is broken off at operation of a safety cushion.
The block of indication and diagnostics gives the operating tension to safety cushions at collision even if the rechargeable battery is disconnected as a result of blow. The block of diagnostics controls a security system every time at launch of the engine, at the same time in a combination of devices the signaling device which in several seconds dies away if the system is serviceable is lit. If in system there are malfunctions, the signaling device will blink and the sound signal will be distributed. In this case it is necessary to address as soon as possible on service station.

       PREVENTION
Before work about sensors of blow, the dashboard and a steering column establish forward wheels for the movement directly forward, switch off ignition, disconnect at first negative, and then positive plugs from the rechargeable battery and wait 2 min. It will exclude unauthorized disclosure of safety cushions and operation of natyazhitel of seat belts which can put injuries.
