<p>Subject of the invention is an automatic device for unbuckling or release of the safety belt upon impact, which enables the automatic unbuckling or release of the safety belt after completed sudden or jerky stress of the safety belt, which is for example the result of an impact, rolling etc. of the vehicle as well as in the case that the vehicle after the event which caused the stress of the safety belt has already been standing still for a certain period of time. The solution of the given task is provided by the submitted automatic device for unbuckling the safety belt upon impact, which is represented by a chamber (5) located on one point of the three-point safety belt (e.g. attachment to the ground), where a piston (11) is moving, where the centrally controlled electromagnetic valve (8), operating depending on the vibration of the complete device operates in opening (6) inside the piston, while the piston (11) movement depends on the open or locked openings (6) inside the piston (11).</p> |
