摘要:
A vehicle safety system includes a module including an airbag and an inflator. The inflator includes a housing (12) in which a combustion chamber (16) containing a pyrotechnic propellant is arranged in which hot gas is generated and which housing includes at least one escape orifice (22) toward the environment of the inflator (10), as well as a coolant reservoir (24) arranged in the housing (12) in which coolant is accommodated prior to activation of the inflator (10) and which has at least one coolant outlet orifice (28′). The coolant outlet orifice (28) is arranged in direct vicinity of the outlet orifice (22). Upon activation of the inflator (10) coolant flows out of the inflator into the protection system and wets an adjacent wall (32) of the protection system against which also the hot gas is flowing.

A device for actuating a vehicle safety system comprises a gas generator (12) having an outer housing (14) and a rigid gas deflection part provided outside the outer housing (14). The device further includes at least one elastic fastening means (18) for the gas deflection part, which presses the gas deflection part, when the gas generator (12) is not actuated, against the latter and with the escaping of gas varies the distance of the gas deflection part from the outer housing (14) depending on the gas pressure. The deflection part can be an integral portion of the fastening means (18).

摘要:
A gas generator, in particular for a vehicle occupant restraint system, has a rigid outer housing (12), a chamber (14) formed in the outer housing (12), in which a compressed gas is present at least upon activation of the gas generator (10), a component immovable (20; 34; 62), at least one outflow opening (22) formed in the component immovable (20; 34; 62) relative to the outer housing (12), and at least one substantially flat, resilient element (26), which is clamped inside the outer housing (12) and rests against the immovable component (20; 34; 62) at least in its normal position. In its normal position, the resilient element (26) closes a flow path between the chamber (14) and external surroundings of the gas generator (10) and is deformed elastically under the influence of compressed gas, whereby it clears a flow cross-section (30) whose size is increasing with increasing pressure.

A vehicle impact protection system (10) includes a vehicle outer wall (16), a vehicle inner wall (14), the vehicle outer wall (16) and the vehicle inner wall (14) defining a mounting space (18) between them, and an elongated reinforcing profile (20) housed in the mounting space (18) and having a profile longitudinal axis (A), the reinforcing profile (20) being connected with an actuator device (28), an activation of the actuator device (28) leading to a change in curvature of said profile longitudinal axis (A) such that the profile longitudinal axis (A) is curved more intensively outwards towards the vehicle outer wall (16) after the activation of the actuator device (28) than before the activation.In one embodiment, an activation of the actuator device (28) leads to a change in curvature of the profile longitudinal axis (A) such that the profile longitudinal axis (A) is curved more intensively outwards towards the vehicle outer wall (16) after the actuator device (28) has been activated than before the activation.In another embodiment, the reinforcing profile (20) has different section moduli transverse to a rotation axis (B) which runs through a first fastening point (22) and a second fastening point (24) of the reinforcing profile (20), the actuator device (28) being able to swivel the reinforcing profile (20) about the rotation axis (B) starting from an initial position, such that the section modulus of the reinforcing profile (20) from the vehicle outer wall (16) towards the vehicle inner wall (14) is greater after the activation of the actuator device than in the initial position.

摘要:
A cold gas generator, comprising a pressure chamber that is filled with pressurized gas, a diaphragm that closes the pressure chamber and that is attached at an attachment edge to a bearing wall, a propellant charge arranged outside the pressure chamber for destroying the diaphragm, and a support wall. The support wall is situated radially inwards from the attachment edge in such immediate vicinity to the interior side of the diaphragm that when an exterior-side pressure is exerted upon it, the diaphragm is deformed towards the interior and makes contact with the support wall before being destroyed.

摘要:
A gas generator comprises an outflow chamber and a freeing element. The outflow chamber contains at least briefly gas under pressure, when the gas generator is activated and at least one outflow opening is arranged in a side wall of the outflow chamber. The freeing element is arranged non-displaceably in the outflow chamber and has a peripheral wall and a base wall. The peripheral wall extends along the side wall and closes at least one outflow opening before an activation of the gas generator. The base wall is connected with the peripheral wall. The freeing element is constructed so that on exceeding a predetermined gas pressure in the outflow chamber, the base wall turns inwards under partial plastic deformation of the peripheral wall and at least one hitherto concealed outflow opening is freed by the plastic deformation of the peripheral wall.
