<p>The invention concerns a device for controlling forces. It concerns a controlling device comprising a body defining a non rectilinear path for passing a strap (18) between two support members (14) arranged on one first side and a support member (16) arranged on the second side, and provided with a sensor of forces experienced during an impact test, each support member (14) being separable from the body. An additional support member geometrically interchangeable with a separable support member (14) is provided with a second force sensor having a measuring range covering the prior working stress of the strap, the controlling device having two different configurations depending on whether a separable member comprises the second force sensor or not. The invention is useful for testing safety belts during impact tests.</p> |
