<p>The present invention relates to an actuator (5, 11) for a hood lifting arrangement in a vehicle pedestrian safety system. The actuator (5, 11) comprises a housing (6, 12) and a piston (7, 17), the piston (7, 17) having a first end (7a, 17a) and a second end (7b, 17b), where the piston (7, 17) is adapted to at least partly be positioned in the housing (6, 12). The actuator (5, 11) further comprises a pyrotechnic charge (8, 19) arranged to exert a displacing force on the piston (7, 17) when the actuator (5, 11) is activated such that the piston (7, 17) is displaced via an opening (6a, 15) in the housing (6, 12), the first end 7a, 17a facing the direction (P) of the piston's displacement. The pyrotechnic device (8, 19) is arranged at the second end (7b, 17b) of the piston (7, 17).</p> |
