Definitions

  • the invention relates to an airbag module with a gas generator which is fixed to the housing with at least one vibration-damping elastic element.
  • the gas generator is provided with an outer circumferential flange, with which at least one element made of an elastic material, preferably rubber, is screwed and therefore vibration-damping element, which is also screwed at its opposite end to the base plate of the module housing and fastened to it.
  • the gas generator is decoupled from the module housing, so that the gas generator can act as a freely oscillating counter mass on vibrations transmitted to the steering wheel unit as the carrier of the airbag module during operation of the vehicle and can dampen these vibrations.
  • the known fastening of the vibration-damping element to the gas generator and base plate has the disadvantage that the screw connection provided is a corresponding one
  • the object of the invention is therefore to create a connection, which is both production-friendly and assembly-friendly and at the same time secure, of the vibration-damping element with the associated gas generator on the one hand and the opposite on the other hand.
  • the invention provides in its basic concept that the vibration-damping element can be clipped with the gas generator and with a housing-fixed opposite by means of clip means formed on it, and projections are arranged on the end faces adjoining the gas generator and housing-fixed opposite, which are deformed when the element is clipped on and thereby generate a bias between the element and the gas generator or the opposite fixed to the housing.
  • the invention has the advantage that due to the provided clip connection manufacture and assembly of the vibration damper are simplified.
  • a clip connection furthermore does not require any additional assembly steps, and due to the prestressing between the vibration-damping element and the opposite, that is to say the gas generator or part fixed to the housing, the vibration-damping element is also secured against slipping.
  • the vibration-damping element has the shape of a notch bearing, which is provided on its outer end faces with a larger diameter than in its slender middle region; such a shape of the vibration-damping element is known in principle from EP 1 010 589 A2, FIG. 3.
  • slotted pegs each extend from the end faces of the vibration-damping element with hooks formed at their free end for forming clip means.
  • the vibration-damping element preferably consists of an elastomer material, it being possible in an expedient manner that the projections are formed from the elastic material of the element.
  • This has the advantage that the projections provided on the end faces of the element can also be attached in one production step, because the projections consist of the same material as the vibration-damping element.
  • the clip connection of the gas generator can either be made with a housing part of the module housing or else with a diffuser connected to the module housing.
  • the single figure shows a vibration-damping element clipped onto a component on one side as a vibration damper in a schematic side view.
  • component 10 with a component is referred to, to which the vibration-damping element 11 consisting of an elastic material is to be attached, with component 10 being a component of the gas generator on the one hand or a housing part of a module housing of an airbag module or one connected to the module housing Diffuser can act.
  • the vibration-damping element 1 1 has the shape of a so-called notch bearing, which has a larger diameter on its outer end faces 12 and 13 than in its slender central region; With this shape, the vibration properties of the element 1 1 are improved.
  • Slotted pins 15 extend from the end faces 12 and 13 of the vibration-damping element 11, on the free end of which outward-pointing hooks 16 are arranged, so that this forms the clip means 14 with which the vibration-damping element can be clipped onto the component 10. by the slotted pins 1 5 in a in the component 10 engage recess 18 and hook hooks 16 under tension behind the surface of component 10.
  • projections 17 are formed, which are designed in their dimensions such that they are deformed by clipping the vibration-damping element 1 1 with the component 10, so that the deformed and then between the component 10 and the element 1 1 lying projections 17 exert a bias on the clip connection.
  • the projections 17 arranged in the region of the upper end face 12 of the element 11 are shown before assembly, while the projections 17 located on the lower end side 13 of the element 11 are compressed by the illustrated clip connection between the element 11 and the component 10 and thereby exert the desired preload.

Abstract

L'invention concerne un module sac gonflable comprenant un générateur de gaz maintenu fixe au boîtier à l'aide d'au moins un élément élastique amortissant les vibrations. L'invention est caractérisée en ce que l'élément (11) amortisseur de vibrations peut être encliqueté respectivement au générateur de gaz et à une contre-pièce fixée au boîtier par un moyen d'encliquetage (14) qui est formé sur cet élément amortisseur de vibrations. Les faces frontales (12, 13) appliquées sur le générateur de gaz et la contre-pièce fixée au boîtier présentent des saillies qui se déforment lorsque l'élément (11) est encliqueté. Une tension est générée entre l'élément (11) et le générateur de gaz ou la contre-pièce fixée au boîtier.
