ABSTRACT:
An automatically disengagable safety buckle assembly utilizes a rod-like element having two free ends. The rod-like element is secured to one end of the flexible safety strap. A plate having a hook-like end is secured to one end of another flexible safety strap. The rod-like element is introduced between a spring-like sheet secured to the plate and another sheet that is spaced non-uniformly outwardly from the side of the plate carrying the hook. The rod-like element is permitted to slide along the spring-like sheet, after entry, to a dwell position which is defined by an outwardly disposed arcuate excursion in the surface of the other sheet. The apparatus is employed prior to impact with the rod-like element reposing in the dwell position. Upon impact, the rod-like element is displaced towards the hook of the plate and continues to restrain the user from unlimited forward travel. After the body finishes its rebound, the rod-like element is forced upwardly and outwardly from the hook of the plate by a ramp-like end of the spring-like sheet that is secured to the plate, causing the rod-like element to become disengaged from between the spring-like sheet, the other sheet and the plate, thus decoupling the rod-like element from the apparatus. An adjustment screw engaging the other sheet and the plate, may be utilized for reducing the tension in the other sheet, so that children may manually disengage the buckle assembly at will, thereby controlling the amount of force required to permit the C-shaped element to become disengaged from its dwell position.
