<p>The retro-tautener has a pyrotechnic propellant and is for an automatic winding mechanism for a safety belt. The explosion pressure generated by the propellant, in the event of an emergency acts on a retrotautening element which tightens the safety belt round the body of the person to be protected. A liquid which transmits the explosion pressure of the propellant is provided between the propellant and the retro-tautening element.</p> |
