1.2.2.6. Conditions of operation of safety cushions

Face-to-face safety cushions work under mentioned below conditions.

– Force of front blow of the car exceeds the set size.

– The direct head-on collision of the car with a rigid not deformable wall at speed of the car is higher than 22 km/h.

– Arrival on a border, the curb or a firm strong subject.

– A rigid landing after a jump or car falling.

– Slanting blow in a forward part of the car, directed within 60-degree sector.

– Hit in a deep hole or collision with a hole wall.

Conditions at which face-to-face safety cushions can not work, are listed below.

– Collision with a tree or column. Despite strong damages of a body to similar failures, longitudinal delay of the car can not exceed the set size at which should work face-to-face safety cushions.

Slanting blow forward part of the car. In this case the longitudinal delay tested by the car, can not exceed the set size at which should work face-to-face safety cushions.

– Collision with a back part of the car or with back protivopodkatny protection of the lorry. The longitudinal delay tested by the car at similar collisions, can not exceed the set size at which should work face-to-face safety cushions.

Further conditions at which face-to-face safety cushions usually do not work are listed.

– Car blow behind.

– Lateral blow of the car. However, the lateral safety cushion and an inflatable shtorka thus can work.

– Car capsizing. Thus can work lateral pillows and inflatable shtorka, but not face-to-face safety cushions.

Lateral safety cushions and inflatable shtorka work, if force of lateral blow (on the right or at the left) exceeds the set level. However, face-to-face safety cushions thus, as a rule, do not work.

Conditions at which lateral safety cushions and inflatable shtorka can not work, are given below.

– Slanting blow forward part of the car. In this case the lateral delay tested by the car, can not exceed the set size at which should work lateral safety cushions and inflatable shtorka.

– Lateral collision with a tree or column. Despite strong damages of a body to similar failures, lateral delay of the car can not exceed the set size at which should work lateral safety cushions and inflatable shtorka.

– Car capsizing. In this case the lateral overloads tested by the car, can not exceed the set size at which should work lateral safety cushions and inflatable shtorka.

– Lateral collision with a two-wheeled vehicle. At similar collisions the lateral overloads tested by the car, can not exceed the set size at which should work lateral safety cushions and inflatable shtorka.

Lateral safety cushions and inflatable shtorka, as a rule, do not reveal in the following cases.

– Car blow behind.

– Front blow of the car. However, in this case can work face-to-face safety cushions.
