A buckle for a vehicle safety restraint for use with a pretensioner has an actuating button (1) for operating a latch for the tongue of the safety restraint. The button (1) is connected eg. via pulleys (17, 18) to a counterbalancing mass to cause the mass to move in an opposite direction to the button. When the pretensioner is operated, and the buckle is retracted, the inertia of the mass (20) counteracts the inertia of the button (1). Thus the button (1) is prevented from moving in relation to the buckle, in a direction which would tend to unlatch the tongue of the safety restraint. |
