Abstract
An airbag tether separation system includes an airbag tether separator having an explosive and a housing including a wall with at least one space formed in the wall. The tether separator is structured so that, when the explosive is activated, the explosive produces shockwaves causing separation of a portion of a tether extending between the explosive and the wall. At least a portion of the shockwaves also pass into the at least one space, from where they may pass through the space away from a separation region of the tether and to an exterior of the housing, or be reflected in a direction away from the separation region of the tether.
Claims20
An airbag tether separation system, comprising an airbag tether separator including an explosive and a housing having a front wall with a plurality of grooves formed therein, the tether separator being structured so that, when the explosive is activated, the explosive produces shockwaves causing separation of a portion of a tether extending between the explosive and the front wall, at least a portion of the shockwaves also passing into at least one groove of the plurality of grooves.

The airbag tether separation system of claim 17, wherein the front wall includes a space formed therein and defined by a pair of surfaces intersecting so as to form an obtuse and concave angle therebetween.
An airbag tether separation system, comprising an airbag tether separator including an explosive and a housing having a front wall with at least one space formed in the front wall, the tether separator being structured so that, when the explosive is activated, the explosive produces shockwaves causing separation of a portion of a tether extending between the explosive and the front wall, at least a portion of the shockwaves also passing into the at least one space, wherein the at least one space comprises a through-hole formed in the front wall.
An airbag tether separation system, comprising:
- an airbag tether separator including an explosive and a housing, the housing having a front wall and a slot;
- and
- a tether extending through an interior of the housing between the explosive and the front wall and out of the housing interior through the slot to a securement location along an exterior of the housing,
- the tether wrapping over a portion of the housing between the slot and the securement location, the tether separation system being structured so that, when the explosive is activated, the explosive produces shockwaves, and wherein the tether separator further comprises a focus sleeve configured to direct the shockwaves and the heat energy produced by the explosive toward the tether to cause separation of the tether in the housing interior.
