If the car is equipped with seat belts with an intermediate bracket regulated on height, it is necessary to extend a belt, to press the bracket case from two parties, as is shown in fig. 1.37
, and to shift a bracket in demanded situation. The humeral branch of a belt should settle down on a shoulder as it is possible closer to a neck, but at all on a neck or a hand. The wrong provision of a belt leads to decrease in its efficiency as means of passive protection at a road accident and increases probability of a travmirovaniye.
