<p>The present invention relates to a device for quick, safe and easy uncoupling a safety belt of a vehicle in a state of emergency.</p><p>The effect of the invention is based on the usage of an extra uncoupling mechanism, mounted between a standard safety belt release device and the chassis or other logic mounting part of the vehicle. This so called emergency release mechanism has been provided with a seal, which after breaking the seal, in case of an emergency, will start a slackening release of the safety belt.
The above mentioned uncoupling has a predefined releasing distance, which will have the effect that occupants can free themselves from critical positions and at the end of this releasing distance there will be a perceptible acceleration in the movement as a signal for definite uncoupling. The distance and the time of this uncoupling moment will be variable and predetermined by the producer. The purpose of the so called perceptible acceleration will have its effect on the occupants by tighten there grip on the safety belt, preventing them from spontaneously falling down or side wards and becoming injured with possible unconsciousness.
