| 发明名称 | Actuator and vehicle protection system | ||
| 摘要 | An actuator, especially for a vehicle protection system, comprises at least one wire (14) variable in shape depending on temperature made from a shape memory alloy and an elongate pyrotechnical element (12) connected to the shape-variable wire (14) so that upon ignition of the pyrotechnical element (12) the wire (14) is heated and experiences a change of length. The vehicle protection system is, for example, an airbag system comprising an airbag and a regulating mechanism for the internal airbag pressure, wherein the wire (14) of the actuator (10) is connected to the regulating mechanism so that a change of shape of the wire (14) exerts a force on the regulating mechanism. | ||
