ABSTRACT:
A seat belt for a pilot seat or flight attendant seat in an aircraft includes a belt tightener with a reversible energy storage member in the form of a helical compression spring and a rod-shaped energy converter coupled to the energy storage member. The energy converter is at least indirectly connected to a belt member of the seat belt. After the belt member has been tightened and the energy converter has been displaced as a result with an at least partial regeneration of the energy storage member, a cutting chisel penetrates the surface of the energy converter and dampens the movement of the belt member. A renewed activation of the energy storage member after the deceleration phase is prevented by the penetration of a clamping edge of a clamping member in the surface of the energy converter.
