Definitions
- the invention relates to a cover for an airbag restraint system with an attached tether embedded in the airbag cover.
- the invention provides a simple to manufacture, inexpensive cover, the kinetic energy of which is largely reduced when torn out of its anchoring and unfolding of the gas bag before the cover hits the windshield. This will be the case with a
- Coverage of the type mentioned is achieved in that the embedding of the tether is carried out in such a way that the cover tears open in the case of retention, when it is retained by the tether, in the area around the exit point of the tether and fastened to the tether by an untorn area remains.
- a large part of the kinetic energy of the cover can be dissipated by tearing open the cover.
- the strain on the tether is significantly lower, and the energy with which the cover hits the windscreen is reduced.
- the cover is torn open only to a certain extent, so that a complete
- the tether is preferably embedded in the cover by extrusion coating or foaming.
- the defined tearing open can take place in that the cover has an inner surface and the tether has a first section embedded in the cover, in which it has an ever decreasing distance from the inner surface up to its exit point.
- the force required to tear open the cover increases continuously with increasing tear-open distance.
- a second embedded extending between the free, embedded end of the tether and the first section
- Section in which the tether has a constant section from the inner surface serves to fasten the cover to the tether after the cover is partially torn open.
- the tether is embedded in such a way that it peels off the cover up to a predetermined point.
- a device for locally limiting the tearing process can be formed, for example, by a molded projection provided on the inside of the cover.
- Figure 1 shows a cross section through part of the invention
- FIG. 2 is a view corresponding to Figure 1 of the cover, which is partially torn after activation of the gas bag restraint system.
- a two-component cover 1 is shown, which has an inner carrier layer 3 and an outer cover layer 5.
- a tether 7 is embedded at one end in the cover 1 by injection molding. From its exit point 9 from the cover 1, the tether 7 extends with a constantly increasing distance from the
- Section B is characterized by a constant distance from the inner surface 11.
- a device 13 in the form of a bead-like projection 13 formed on the inside of the cover by injection molding extends transversely to the longitudinal extent of the tether 7.
- the width of the device 13 corresponds to that of the tether 7, but it can also be wider.
- the device 13 serves for local limitation of the defined partial tearing of the cover 1 which occurs in the case of retention when the cover is torn out of the anchoring.
- the tether 7 limits the movement of the cover 1. As soon as the tether 7 is sufficiently subjected to tension by the flung cover 1, the carrier layer 3 tears, as in FIG Figure 2 shown, starting from the exit point 9 in the area of the first section A of the tether 7 and approximately over the tether. As a result, part of the kinetic energy of the cover 1 is reduced. The tether 7 peels the cover 1 over the length of section A until the
- Device 13 is reached, which is arranged at the transition between sections A and B.
- the device 13 thus limits the tearing process. Since the tether 7 in section A is increasingly at a greater distance from the inner surface 11, the force required to tear open the cover 1 also increases continuously. The cover 1 is therefore not abruptly, but steadily braked, which can reduce the tether load.
- the embedding of the tether 7 in section B in connection with the device 13 is selected so that a complete tearing of the tether 7 from the cover 1 is excluded.
