US12503073 - Triggerable holding apparatus

The invention relates to a triggerable holding device ( 10 ) for a tensioning means ( 12 ) of an airbag, comprising a holder ( 14 ), a locking member ( 16 ) that is movably supported in the holder ( 14 ) and that is shiftable between a locking position in which it keeps the tensioning means ( 12 ) locked and a release position in which the tensioning means ( 12 ) is released, a pyrotechnical device ( 22 ) which is coupled to the locking member ( 16 ) so that, when the pyrotechnical device ( 22 ) is activated, it is shifted from the locking position to the release position, and a restraining device ( 38 ) which is tightly connected to the locking member ( 16 ) and which, in the release position of the locking member ( 16 ), interacts with a restraining geometry ( 40 ) within the holder ( 14 ) to hold the locking member ( 16 ) in its release position within the holder ( 14 ).

The patent describes a triggerable holding device for an airbag’s tensioning means, featuring a movable locking member that can shift between locked and released positions through activation of a pyrotechnical device. Additionally, a restraining device ensures the locking member remains in the release position once activated, enhancing the safety mechanism of the airbag system.

Claim 1

1 . A triggerable holding device for a tensioning means of an airbag, comprising a holder, a locking member that is movably supported in the holder and that is shiftable between a locking position in which it keeps the tensioning means blocked and a release position in which the tensioning means is released, a pyrotechnical device that is coupled to the locking member so that, when the pyrotechnical device is activated, it is shifted from the locking position to the release position, and a restraining device that is tightly connected to the locking member and that interacts, in the release position of the locking member, with a restraining geometry in the holder to hold the locking member in its release position in the holder, wherein the restraining device is formed on a base in which the locking member is held, the restraining device projecting laterally from the base. a holder, a locking member that is movably supported in the holder and that is shiftable between a locking position in which it keeps the tensioning means blocked and a release position in which the tensioning means is released, a pyrotechnical device that is coupled to the locking member so that, when the pyrotechnical device is activated, it is shifted from the locking position to the release position, and a restraining device that is tightly connected to the locking member and that interacts, in the release position of the locking member, with a restraining geometry in the holder to hold the locking member in its release position in the holder, wherein the restraining device is formed on a base in which the locking member is held, the restraining device projecting laterally from the base.
