Abstract: Body restraint systems for vehicles that include buckles for latching and retaining latch plates associated with safety belts. The buckle of each system includes a pair of oppositely biased latching mechanisms that are operative in such a manner that a force applied to release one latching mechanism from a latch plate inserted within the buckle creates an opposite and equal force against the opposite latching mechanism to thereby positively retain the latch plate within the buckle in a locked position. Release of a latch plate can only occur upon the simultaneous movement of both of the oppositely biased latching mechanisms toward one another by application of manual force and thus release of the latch plate cannot occur by inertial forces that may be encountered in a vehicular accident.

Abstract: A latching fastener having cocking and triggering mechanisms is provided. The fastener has two flexible fastening latch arms each fixed at a proximal end of the arm and having a free distal end. The two arms are located relative to each other to cooperate in grasping a structure between them. A fastener cocking mechanism is connected to the fastening latch arms for retracting the distal ends of the arms when the cocking mechanism is activated, to thereby produce a latching gap between the distal ends of the arms. A trigger mechanism is located between the fastening latch arms such that a structure guided into the latching gap can activate the trigger, for deactivating the cocking mechanism, which in turn results in closing together of the distal ends of the fastening latch arms, to grasp the structure between them and latch the structure to the fastener.

Abstract: An axial locking device has locking balls which engage in a groove in a male member to lock the male member to a female member. To effect locking, a first axial movement of the male member causes it to abut an end surface on a slider and pushes slider teeth against rotor teeth, and a return movement of the male member allows the slider and rotor to return, pushed by a spring. In this way, the rotor is caused to rotate and its internal cam surface moves the locking balls. To reduce the number of parts and simplify manufacture, retaining teeth are formed by U-shaped clips on the housing of the female member, and act to prevent rotation of the slider during its axial movement, and to prevent rotation of the rotor until the rotor teeth have cleared the retaining teeth, causing a click or snap action. During the return movement of the slider and rotor, the rotor teeth cam over the ends of the retaining teeth and continue to rotate the rotor in the same direction.
