Embodiment Construction

[0056] FIG. 1 shows an embodiment according to the invention of an ignition device 11 for a pyrotechnic protective device, in particular an airbag or a belt pretensioner, in an axial section in a schematically simplified illustration. The device comprises a current conducting bushing, in particular a metal-fixing material bushing 2, in particular in the form of a glass-metal bushing 3 for electronic ignition, and a metal-fixing material bushing 2 connected A cover 4 encloses a propellant charge 5 between the glass-metal insulating sleeve 2 and the cover 4 . The glass-metal insulating bushing 2 , in particular in the form of a glass-metal insulating bushing 2 , surrounds at least one metal pin 6 , which is melted in the base body 8 in the passage opening 7 in the fixing material 9 . The base body 3 here preferably has a disk-shaped basic shape and forms, with its end sides 10 and 11 , a front side 12 and a rear side 13 . The base body preferably has a thickness of from 0.1 mm...

Abstract

The invention relates to an apparatus, in particular a firing apparatus (1) for a pyrotechnic protection apparatus, in particular an airbag or belt pretensioner, comprising: a power leadthrough, in particular a metal fixing material leadthrough (2), comprising a base body (8) which is provided with a passage opening (7), and at least one metal pin (6) which is arranged in the passage opening (7) in the base body (8) in a fixing material (6); a housing part (19, 4) which at least partially accommodates the power leadthrough so as to form a space for accommodating a propellant charge (5); a casing (22) which at least partially surrounds the power leadthrough (2), the metal pin (6) and the housing part (19, 4); wherein the base body (8) has a thickness D in the range of from 2.0 mm to 0.1 mm, preferably in the range of from less than 1.0 mm to 0.1 mm, in particular less than 0.8 mm to 0.5 mm, and means (27) are provided on the metal pin (6) in such a way that the casing (22) engages with the metal pin, wherein the casing and the base body together absorb a pull-out force of the metal pin which is greater than 150 N, in particular greater than 165 N, preferably greater than 200 N, in particular greater than 250 N, in particular greater than 300 N.

Description

technical field [0001] The invention relates to a hermetically sealed ignition device for a pyrotechnic protective device, in particular to a hermetically sealed ignition device for a pyrotechnic protective device according to the preamble of claim 1; the invention It also relates to a pyrotechnic protective device, in particular an airbag and a seat belt pretensioner with such an ignition device, and a method of manufacturing a metal-fixing material insulating sleeve for a pyrotechnic protective device. Background technique [0002] Ignition devices for pyrotechnic protective devices are known in various embodiments from the prior art. In automobiles, these ignition devices are mainly used in seat belt pretensioners or air bags. The ignition device comprises a metal-fixed-material insulating bushing for the current-conducting insulating bushing and a cover which is designed to be open on one side and which, in the open area, accommodates the fixed metal-material insulating...
