A safety belt is adapted to be applied to a person who occupies a seat. Belt-fixing means are adapted to releasably hold said belt in position for retaining such person on said seat when said belt is applied to such person. First and second control elements are movable relative to each other in a predetermined direction to an enabling position in response to a tensile load on said belt in excess of a predetermined value. Detent means are arranged to prevent a movement of said first and second control elements relative to each other out of said enabling position opposite to said predetermined direction. A drive spring is connected to said first and second control elements and arranged to be stressed as they move in said predetermined direction. A retarding mechanism is adapted to perform a predetermined stroke under the action of said spring when said first and second control elements are in said enabling position. Belt-releasing means are arranged to release said belt from said belt-fixing means when said retarding mechanism has completed said predetermined stroke.
