The invention relates to an unlocking device (), especially for a vehicle protection device, comprising a locking bar () which in a locked position establishes a connection positive at least in portions between a first component () to be unlocked and a second component () and permits relative motion of the two components () in an open position. The unlocking device () further comprises a pyrotechnical actuator () including a pyrotechnical element () having a propelling charge and a piston-cylinder unit () having a piston () and a cylinder (), wherein motion of the piston () or the cylinder () can be generated due to activation of the propelling charge upon ignition thereof and wherein the piston-cylinder unit () is connected to the locking bar () without redirection so that upon motion of the piston () or the cylinder () the locking bar is movable from its locked position into its open position.

Unlocking device

A gas generator for a vehicle occupant restraint system a rigid outer housing (), a chamber () formed in the outer housing (), in which a compressed gas is present at least upon activation of the gas generator (), a component immovable () relative to the outer housing (12), at least one outflow opening () formed in the immovable component (), and a least one resilient element (), which is clamped inside the outer housing () and rests against the immovable component () at least in its normal position. In its normal position, the resilient element () closes a flow path between the chamber () and external surroundings of the gas generator () and is deformed elastically under the influence of compressed gas, whereby it clears a flow cross-section () whose size is increasing with increasing pressure.

Gas generator

A gas generator has a cylindrical gas generator housing () and a connecting piece () which is welded to the gas generator housing (). The connecting piece () has extensions () spaced apart in peripheral direction on the side facing the gas generator housing () and has a recess () between the extensions (). The connecting piece () is welded to the gas generator housing () at the extensions ().

Gas generator and a gas bag module

A hybrid gas generator for use in a vehicle occupant restraint device comprises at least one combustion chamber containing a pyrotechnic charge, and at least one fluid chamber containing a fluid. Several movable pistons are provided which push the fluid out from the at least one fluid chamber. The pistons are able to be set in motion independently of each other and/or in any activation sequence desired.

Hybrid gas generator

A gas generator with a housing (,), and outflow opening (,) in the housing (,), via which gas can emerge, and with a bursting membrane (,) which closes the outflow opening in the non-activated state of the gas generator and which is destroyed on activation, the bursting member (,) having an outer edge at which it is permanently fastened to a wall (,) which defines at least one axial section of the outflow opening (,), is characterized in that the wall (,) is rounded or extends inwards and obliquely in the outflow direction downstream immediately after the fastening region (,) of the bursting membrane (,).
