摘要:
A safety arrangement for a motor vehicle includes a pyrotechnic actuator for retracting a hinge pin of a vehicle hood. The pyrotechnic actuator includes a housing defining a longitudinal axis and further includes a first end defining an opening. The pyrotechnic actuator additionally includes a piston disposed in the housing for movement along the longitudinal axis between an extended position and a retracted position. The piston carries the pin. The pin at least partially extends from the housing in the extended position. The piston includes a base portion defining a combustion chamber. The pyrotechnic actuator further includes a pyrotechnic charge disposed in the combustion chamber for producing a combustion gas operative to move the piston from the extended position to the retracted position. The combustion chamber is defined by a thin walled member that is sealed to contain the ballistic event.
