Abstract

An impact minimisation device for incorporation into safety belts consists of a U-form metal strip base into which an impact reducing semi-circular upward bowed flat spring is set. This spring is fixed to the U-form metal base at one end but left free at the other pressure reducing end. Two belts to fix the spring into the U-form metal strip base penetrate the upturned edge of the base and are retained by split pins. In the event of accident the safety belt which normally runs freely below the bolts and over the spring is pulled sharply against the spring which bows up further to prevent excessive movement of the belt.

Description

Betr. B E S a X R E I B U N G des zum Patent angemeldeten AUFPRALL- Minderungs- Gerät (nachträgl. einzubauen in jeden handelsübl.Sicherheitsgurt! Bei o.a. Aufprall Minderungsgerät handelt es sich um einen Shockabsorber für Auto-Sicherheitsgurte,welcher einen giossen Teil der bei einer Vollbremsung bezw. Zusammenstoss entstehenden Aufprall- Kräfte durch eine sich im Moment des Zusammenstosses sich zusammendrückende und sich wieder dehnende Blattfeder,welche in das U förmige Gerät eingepasst ist, ableitet - und somit eine im Gefahrenmoment zu strenge und meist unfallschädliche Straffung des Sicherheitsgurtes v e r m e i d e t Dadurch wird gewährleistet,dass die Wirkung des Sicherheitsgurts im Falle eines Unfalls nicht die Wirkung eines sofort einschneidende straffen Gurtes mit eventuellber gesundheitlicher Schädigung hat,-sondern im Gefahrenmoment tritt zwar die Schutz bzw. Sicherheitswirkung des Gurts v o 1 1 ein,wird jedoch durch die den sofortigen Aufprall abfangende FEDER iD ein risiko-vermeidendes sanfteres Abfangen des Aufpralls verwandelt.Re. B E S a X R E I B U N G of the patent-pending IMPACT Reduction device (to be retrofitted in every commercially available seat belt! o.a. Impact mitigation device is a shock absorber for car seat belts, which a poured part of the BEZW during an emergency stop. Collision resulting impact Forces due to a squeezing and at the moment of the collision again expanding leaf spring, which is fitted into the U-shaped device, derives - and thus a tightening that is too strict and usually harmful to accidents in the moment of danger of the seat belt avoids this ensures that the effect the seat belt in the event of an accident does not have an immediate impact taut belt with possible health damage, but in the moment of danger although the protection or safety effect of the belt v o 1 1 occurs, it will Thanks to the FEDER iD which absorbs the immediate impact, it is more gentle and risk-avoiding Intercepting the impact transformed.

Dadurch ist garantiert,dass die Schubkräfte,welche bei angelegten Sicherheitsgurten im Falle eines Zusammenstosses entstehen,durch die Wirkungsweise-wie beschrieben - abgemindert und für den Gurtanleger ungefährlicher sich auswirkenThis guarantees that the shear forces that are applied when Seat belts arise in the event of a collision, by how they work described - reduced and harmless for the belt feeder
