ABSTRACT:
A motion-restraining device for dissipating at a controlled rate the force of a moving body. The device is characterized by a drive shaft adapted to be driven in rotation by a moving body connected thereto through a tape wound about a reel mounted on the drive shaft, oscillatable mass, a crankshaft connected with the drive shaft, and an elongated pitman link having one end pivotally connected to the crankshaft and the opposite end thereof connected with the mass through an energy dissipating linkage including a shuttle disposed within a slot and guided thereby for rectilinear motion between a pair of spaced impact surfaces so configured that reaction forces applied at impact of the shuttle with the impact surfaces include oppositely projected force components angularly related to the direction of the applied impact forces, whereby a cancellation of components of reaction forces is achieved.
