Αερόσακος 25 ετών...

[BILL007]

Ο αερόσακος κλείνει 25 χρόνια ως πατέντα. Η εταιρία που τον προτοέβαλε ήταν μια αγαπημένη μας γερμανική,αλλά δυστυχώς όχι η BMW.
H Mercedes λοιπόν έφτιαξε ένα σύστημα που μετά απο τόσα χρόνια θεωρείται πλέον must ακόμα και στο πιο φτηνό αυτοκίνητο παραγωγής.

αερόσακε!

To 1987 - πριν από 25 χρόνια - η Mercedes παρουσίασε για πρώτη φορά τον αερόσακο οδηγού. Η παρουσίαση πραγματοποιήθηκε το φθινόπωρο του 1987 στο Σαλόνι Αυτοκινήτου της Φρανκφούρτης. Ο πρώτος αερόσακος τοποθετήθηκε στη σειρά S-Class. Ηταν μια καινοτομία η οποία εξελίχθηκε και υιοθετήθηκε πολύ γρήγορα και από άλλες αυτοκινητοβιομηχανίες. Ο αερόσακος οδηγού τοποθετήθηκε πολύ γρήγορα και σε άλλα μοντέλα της γερμανικής φίρμας, ενώ λίγο αργότερα παρουσιάστηκε και ο αερόσακος συνοδηγού. Ο τελευταίος στην αρχική μορφή του και λόγω του μεγάλου όγκου του θυσίασε τα ντουλαπάκια του συνοδηγού, που για χάρη του αερόσακου έλειπαν από τα μοντέλα της εποχής.
Η πρώτη S-Class με αερόσακο οδηγού προσφερόταν στάνταρ και με τη ζώνη ασφαλείας με προεντατήρα. Σήμερα δεν υπάρχει αυτοκίνητο χωρίς αερόσακους, ενώ από την εμφάνισή του έως και σήμερα χάρη στον αερόσακο έχουν σωθεί αμέτρητες ζωές. Αργότερα εμφανίστηκαν οι πλευρικοί αερόσακοι ώστε να προστατεύουν τους επιβάτες από τις πλευρικές συγκρούσεις, οι αερόσακοι γονάτων και οι αερόσακοι κεφαλής.
Σε λίγο καιρό θα κάνουν την εμφάνισή τους και οι αερόσακοι που θα είναι ενσωματωμένοι στις ζώνες ασφαλείας.
Η Ford είναι από τις πρώτες εταιρείες που έχει επενδύσει σημαντικά στον αερόσακο στη ζώνη ασφαλείας.

Και το δελτίο τύπου της Mercedes:

• The protective air cushion for the front passenger celebrated its debut in 1987 in the 126 model series
• An evolution of the airbag technology introduced by Mercedes-Benz in series production in 1981
• The optional equipment of that time is an industry standard in safety technology today
  
  Stuttgart – 25 years ago Mercedes-Benz was the first automobile manufacturer in the world to introduce the front passenger airbag in a series-production car. The technology debuted in the S-Class (model series 126) at the Frankfurt International Motor Show in September 1987. It elevated the safety standards in Mercedes-Benz passenger cars to a new level and thus represented yet another logical step by the pioneer in passive vehicle safety in a long line of outstanding innovations.
  
  Mercedes-Benz had already introduced the worldΆs first fully operational driver airbag in a production vehicle in 1981 – also in a 126 model series S-Class. The Supplemental Restraint System (SRS), consisting of driver airbag and belt tensioner, was available as an option for DM 1525.50. It was the result of the rigorous work undertaken by corporate research that had started in the mid-1960s. When sensors detect a collision, a propellant charge is ignited and within a few milliseconds the nitrogen produced by this process inflates a bag made out of a special woven material. The resulting cushion protects people against impacting the dashboard. While the driver airbag is housed in the steering wheel, the front passenger airbag in its early manifestations occupied the spot where the glove compartment would normally have been. Thanks to refined and smaller airbag modules vehicles later regained the glove compartment.
  
  The front passenger airbag introduced in 1987 utilised the same technology as the innovative driver protection system. It went on sale as an option on S-Class saloons and coupés in February 1988. Soon afterwards Mercedes-Benz also offered the front passenger airbag as an option in the mid-size model series 124. As early as 1994 the front passenger airbag became standard on all Mercedes-Benz passenger cars; the driver airbag had already been part of the standard equipment of all passenger car models since 1992. To further improve the protective effect afforded by airbags, the Mercedes-Benz engineers went on to develop additional systems such as the side airbag and the side curtain airbag in the years that followed.
  
  Research in the interest of safety
  
  Mercedes-Benz has shaped not only the history of the modern airbag to a significant extent, but the development of vehicle safety in general: this includes such pioneering innovations as the safety body shell with rigid passenger cell, front and rear crumple zones as well as the safety steering column. Airbag technology expanded the arsenal of passive safety by another powerful tool. Mercedes-Benz research on the airbag began in 1966, with initial practical trials starting in 1967.
  
  Mercedes-BenzΆs fundamental goal was to further increase vehicle safety. The development of the airbag was also driven by plans in the United States of America to prescribe an automatic occupant protection system for all cars from 1969. Airbags that inflate during an accident were seen as a very promising technology. The principle had already been patented in the 1950s. The principal pioneers were the German Walter Linderer (Patent DE 896312 of 6 October 1951) and the American John W. Hedrik (U.S. Patent 2649311 of 18 August 1953).
  
  But it was a rocky road from the concept to production-ready technology. Particularly the necessary sensor systems and gas generation continued to present major challenges to the developers. This was evident in the solutions from American manufacturers, which equipped their first test fleets with compressed-air operated airbags as an alternative to seat belts: this concept led to serious injuries and in a few cases even fatalities. For this reason the engineers at Mercedes-Benz chose a different approach to arrive at the “inflatable container in a folded state, which automatically inflates in the event of danger” (LindererΆs description of his invention in the patent application): the airbag was not to replace the restraining effect of the seat belt, rather it was to supplement it. Tests showed that the airbag only achieved maximum effectiveness in combination with the safety belt. In addition, the gas was not stored under high pressure, but generated on demand by igniting a propellant charge.
  
  The findings of Mercedes-Benz research were formulated in patent no. DE 2152902 C 2, which former Daimler-Benz AG filed on 23 October 1971. This patent application was the key document for all subsequent airbag development at Mercedes-Benz. It already described the operating principle of the new technology as it was to be implemented in series production ten years later: sensors register the particularly severe deceleration common to collisions and activate the airbag mechanism. This ignites a propellant charge (at the time consisting of sodium azide, potassium nitrate, and sand), which deflagrates instantaneously to form mainly gaseous nitrogen and every a little water and oxygen.
  
  The airbags for driver and front passenger quickly caught on in the entire industry as a life-saving technology. As airbag modules became smaller and smaller thanks to the rigorous work of the engineers, it was possible to incorporate them in other areas of a vehicle to also provide comprehensive protection in the event of a side impact: in 1993, Mercedes-Benz presented a study of a side airbag; in 1995 the side airbag became available as an option, initially in the E-Class. Further innovative steps were the side curtain airbag, the head-thorax sidebag and adaptive airbags that operate in different stages depending on the expected severity of the accident and provide optimal protection for the occupants.
  
  Did you know…?
  
  Mercedes-Benz Classic will be at the Goodwood Revival (14 to 16 September 2012) with five original Silver Arrows of the 1930s – and will compete in a demonstration run with racing cars of Auto Union. It will be the biggest assembly of Silver Arrows since decades.

A Short History of the Airbag

An accident during a Sunday afternoon trip to the Pennsylvania countryside inspired John W. Hetrick to design one of the most important advances in automobile safety.
Hetrick, a retired industrial engineering technician, received a patent in 1953 for what he called a "safety cushion assembly for automotive vehicles." His U.S. Patent No. 2,649,311 was the first prototype for today's modern airbags.

Hetrick designed the system to reduce injuries during emergency braking and frontal collisions, according to a story in American Heritage about his invention.

In that story, Hetrick recalled the inspiration for his invention: "In the spring of '52, my wife, my seven-year-old daughter, Joan, and I were out for a Sunday drive in our 1948 Chrysler Windsor. About three miles outside Newport, we were watching for deer bounding across the road. Suddenly, there was a large rock in our path, just past the crest of a hill. I remember hitting the brakes and veering the car to the right. We went into the ditch but avoided hitting both a tree and a wooden fence.


"As I applied the brakes, both my wife and I threw our hands up to keep our daughter from hitting the dashboard ... during the ride home, I couldn't stop thinking about the accident. I asked myself: 'Why couldn't some object come out to stop you from striking the inside of the car?'"

When he returned home, Hetrick started sketching designs for his "safety cushion."


On August 5, 1952, he filed his disclosures and waited more than a year for his patent. The process cost him about $250.

German inventor Walter Linderer also received a patent in 1953 for an "inflatable cushion" to protect drivers in accidents.

Their early airbag designs inspired others in the automotive industry to work on this safety feature. Ford and General Motors, for example, started experimenting with inflatable restraints in the late 1950's.


The companies quickly discovered several challenges associated with this safety feature: it must be able to quickly and accurately sense a collision and it must inflate in 40 milliseconds or less.
Car makers also faced another challenge with airbags: They could cause secondary injuries when passengers came in contact with them.


In 1967, carmaker Mercedes-Benz started to develop airbags for its vehicles. Two developments prompted that move: the rapid increase of accidents during the 1960s, and a new federal law that mandated 'automatic occupant protection systems' for every car in the USA starting in 1969.

"We can no longer tolerate unsafe automobiles," then President Lyndon B. Johnson said.

In the late 1960's, a New Jersey mechanical engineer named Allen K. Breed invented a device that many say gave birth to the airbag industry.

Breed invented a reliable, five dollar crash sensor. His crash sensing technology -- the only one of its kind -- is considered the world's first electromechanical automotive airbag system.

Breed's role in automotive safety didn't stop there. He helped designed more than two dozen other car safety inventions, including an airbag that vents air as it inflates. This 1991 invention -- patent No. 5,071,161 -- was designed to "reduce the risk of secondary injuries by reducing the inflated bag's rigidity."

Breed later started his own company, which became the world's top manufacturer of crash-sensor supplies and inflator-modules.

Today his company, Key Safety Systems, Inc., designs and produces airbags, seatbelts, steering wheels, and other safety systems.

Τον αερόσακο τον έχει εφεύρει ο Αλκιμένης ο Στούκιος, τον 5ο Π.Χ αιώνα και τον είχε εγκαταστήσει στην αμαξά του με ειδικά μηχανισμό στον κώλο του αλόγου του.
Οταν το άλογο τράκαρε με άλλο αλογο ή τούμπαρε η άμαξα, ενας άξονας ασκούσε πίεση στην κοιλιά του αλόγου, το οποίο αμόλαγε μια παληκαρίσια και γέμιζε ο αερόσακος.

Μόνο πρόβλημα ήταν πως αν ταυτόχρονα είχε τουρμποκλανιέρα ή πάταγε καρότα άδειαζε το άλογο απο αέριο και δεν φούσκωνε καλά ο αερόσακος.

Αυτά τα έχω αναλύσει στο παρελθόν σε ΑΥΤΟ το θρεντ.

Τα πάντα έχουν ξεκινήσει απο την αρχαία ελλάδα.

οταν εμείς φτιάχναμε αερόσακους, αυτοί δεν είχαν ανακαλύψει τον τροχό ακόμα.
