FIELD: transport engineering; safety seat belts. SUBSTANCE: proposed seat belt tension adjuster has tension spring whose effort is taken up by lever at normal driving. Additional end lever is used to decrease indicated effort which acts on roller, then on stop member, then on other roller and at last on support. Stop member is included into pusher which, at deceleration of automobile, is brought out by inertia mass from zone between rollers, overcoming resistance of control spring, and, if preset deceleration value is exceeded, roller moves away from side surface of stop member, system of levers turns and releases drive cable of tension spring. Tension spring entrains seat belt lock downwards through return stop, thus providing tensioning of seat belt. EFFECT: improved safety. |
