Device for accelerating a person supported on rolling or sliding devices

摘要

The draw cable (3) comprises at least over a part area an expansion-elastic material and is fixed on one side to a fixture point (7). The draw cable is connected via a releasable coupling (12) with tension devices (4) which stretch it. The coupling has a brake device (21) limiting the acceleration of the person (2). The tension devices consist of a tension cable (8) connected to a vehicle or a winch. The releasable coupling can comprise a figure of eight fixed to the tension cable and a start cable (20) fixed to the draw cable. The start cable may penetrate several times a loop of the figure of eight.
