Description

Anordning ved spenne for sikkerhetsbelter o. 1. for avpasning av beltets lengde. Device at the buckle for safety belts etc. 1. for adjusting the length of the belt.

Den foreliggende oppfinnelse går ut på en lengeinnstillingsanordning ved spenner som er bestemt for sikkerhetsbelter og lignende og utført i form av en ramme i hvis åpning en bom er forskyvbar i beltets trekkretning for å klemme beltet fast mot den ene kant av rammeåpningen. The present invention is based on a length adjustment device for buckles which is intended for safety belts and the like and made in the form of a frame in the opening of which a boom is displaceable in the belt's pulling direction to clamp the belt firmly against one edge of the frame opening.

Slike spenner er alminnelig kjent og anvendt ved sikkerhetsbelter i motorkjøre-tøyer, hvor strekkpåkjenningen i beltet ved ulykker kan gå opp i meget store ver-dier. Det er således av største betydning at faren for glidning av beltet i spennen i størst mulig grad er ryddet av veien. Such buckles are commonly known and used for safety belts in motor vehicles, where the tensile stress in the belt in accidents can rise to very large values. It is thus of the greatest importance that the danger of the belt slipping in the buckle is cleared out of the way as much as possible.

Oppfinnelsen tar sikte på en kon-struksjon hvor der oppnås en effektiv fast-klemning av beltet i spennen. Konstruk-sjonen er dessuten slik at beltets innstilling på forskjellige lengder i stor utstrekning lettes. Oppfinnelsen er hovedsakelig karakterisert ved at en i tverrsnitt sylindrisk klem-skinne ligger an langsmed og omslutter bommens ene side, undersiden, samtidig som beltet danner en sløyfe som ligger rundt såvel bommen som skinnen, således at beltets endepartier befinner seg på énog samme side (oversiden) avspennen, mens skinnen på bommens klemside bevirker en utbuktning av beltesløyfen, så denne bringes til å følge en S-formet kurve, hvorved låsning finner sted langs to innbyrdes parallelle soner. The invention aims at a construction where an effective clamping of the belt in the buckle is achieved. The construction is also such that the adjustment of the belt to different lengths is greatly facilitated. The invention is mainly characterized by the fact that a cross-section cylindrical clamping rail lies longitudinally and encloses one side of the boom, the underside, at the same time that the belt forms a loop that lies around both the boom and the rail, so that the end parts of the belt are located on one and the same side (the upper side ) the tensioner, while the rail on the clamping side of the boom causes a bulge in the belt loop, so that it follows an S-shaped curve, whereby locking takes place along two mutually parallel zones.

Tegningen viser et utførelseseksempel på oppfinnelsen. The drawing shows an embodiment of the invention.

En rammeformet spenne 1 er på i og for seg kjent måte utført med en hovedsakelig rektangulær åpning 2 og forsynt med en i tverr-retningen forskyvbar bom 3, hvis endepartier er utformet med hvert sitt diametrale spor 4. Bommen er anbragt slik at to motstående kanter av åpningen griper inn i disse spor. A frame-shaped buckle 1 is made in a manner known per se with a mainly rectangular opening 2 and provided with a transversely displaceable boom 3, the end parts of which are each designed with a diametrical groove 4. The boom is arranged so that two opposite edges of the opening engages in these grooves.

Ifølge oppfinnelsen er der på bommens ene side anbragt en skinne 5 med sylindrisk tverrsnitt. Skinnen ligger an langsmed bommen og omslutter denne partielt, så bommen og skinnen sammen danner et stangformet legeme hvor to motstående sylindriske sideflater har forskjellig store radier. According to the invention, a rail 5 with a cylindrical cross-section is placed on one side of the boom. The rail lies along the boom and partially encloses it, so the boom and the rail together form a rod-shaped body where two opposite cylindrical side surfaces have different radii.

Beltets ene gren er betegnet med 6 og den annen med 7. En sløyfe av beltet er lagt omkring bommen og skinnen på en slik måte at de to beltedeler befinner seg på én og samme side av spennen og hol-des sammen av en hempe 8. One branch of the belt is designated by 6 and the other by 7. A loop of the belt is placed around the boom and the rail in such a way that the two belt parts are on one and the same side of the buckle and are held together by a loop 8.

Beltedelen 6 skal oppta strekkbelast-ningen, noe som fører til at bommen for-skyves i trekkretningen og klemmer beltedelen 7 ved sløyfen mot den ene langsgående kant av åpningen 2. Denne kant dannes i eksempelet av en U-formig bøyet be-skyttelsesplate 9 med rette ben som ligger an mot spennens rammedel 10. Beltet vil således bli klemt fast mellom bommen og et mykt avrundet ryggparti av platen 9. Skinnen 5 har slik tykkelse og bredde at den i den trykksone som fås ved hjelp av bommen, bevirker en utbuktning av beltesløy-fen, så denne bringes til å følge en S-formet kurve. Beltet blir herunder fastlåst dels mellom bommen og ryggpartiet av platen 9 og dels mellom skinnen og dette ryggparti, d.v.s. langs to innbyrdes parallelle soner. The belt part 6 must take up the tensile load, which causes the boom to be shifted in the pulling direction and clamps the belt part 7 at the loop against one longitudinal edge of the opening 2. This edge is formed in the example by a U-shaped bent protection plate 9 with straight leg that rests against the frame part 10 of the buckle. The belt will thus be clamped between the boom and a softly rounded back part of the plate 9. The rail 5 has such thickness and width that in the pressure zone obtained by the boom, it causes a bulge of the belt loop, so that it follows an S-shaped curve. The belt is then locked partly between the boom and the back part of the plate 9 and partly between the rail and this back part, i.e. along two mutually parallel zones.

Som vist på fig. 3 strekker skinnen 5 seg så langt utenfor bommens ender at der dannes et fingergrep 11 hvormed skinnen lettvint kan fjernes fra bommen et ønsket stykke uten uttrekning av belte-sløyfen for endring av beltets lengde. Skinnen føres derefter igjen til inngrep med bommen, enten ved trekk i delen 6, hvorunder beltet forlenges, eller ved trekk i delen 7, hvorved beltet innkortes. As shown in fig. 3, the rail 5 extends so far beyond the ends of the boom that a finger grip 11 is formed with which the rail can easily be removed from the boom a desired distance without pulling out the belt loop to change the length of the belt. The rail is then brought back into engagement with the boom, either by pulling in part 6, during which the belt is extended, or by pulling in part 7, whereby the belt is shortened.

For at skinnen skal kobles sammen med beltet så den kan gli langs dette, men ikke fjernes fra beltet, er skinnen ved sine endepartier fast forbundet med en skjede 12 som ligger utenom skinnen og er formet slik at den holder beltet i anlegg mot skinnen. I eksemplet er skjeden utformet med en hensiktsmessig rektangulær åpning 13, hvis lengde motsvarer beltedelens bredde, og hvis bredde er hovedsakelig lik bred-den av skinnen, mens to langsgående kantpartier 14 av skjeden følger skinnens langsgående kantpartier i en viss avstand. Åpningen 13 letter innføring av beltet rundt skinnen. Skjeden kan utføres slik at finger-grepet 11 ved skinnenes endepartier blir større og bedre. In order for the rail to be connected to the belt so that it can slide along this, but not be removed from the belt, the rail is firmly connected at its end parts to a sheath 12 which lies outside the rail and is shaped so that it holds the belt in contact with the rail. In the example, the sheath is designed with an appropriate rectangular opening 13, the length of which corresponds to the width of the belt part, and whose width is substantially equal to the width of the rail, while two longitudinal edge portions 14 of the sheath follow the longitudinal edge portions of the rail at a certain distance. The opening 13 facilitates insertion of the belt around the rail. The sheath can be made so that the finger grip 11 at the end parts of the rails becomes larger and better.

Spennen 1 kan være fast forbundet med en lengdefiksert beltedel, idet den rammedel 18 som begrenses av kanten 16, er utformet med en dertil bestemt sliss-formet åpning. The buckle 1 can be firmly connected to a length-fixed belt part, as the frame part 18 which is limited by the edge 16 is designed with a slit-shaped opening determined for that purpose.
