A closure device for closing and locking a restraint system, such as a restraint system for an amusement vehicle, includes a blocking device, and a locking device having a first connecting member and a second connecting member. The locking device and the blocking device interact in such a way that, in at least a first position of the locking device relative to the blocking device, the first connecting member is releasable coupled to the second connecting member. Furthermore, in at least a second position of the locking device relative to the blocking device, the blocking device prevents release of the first connecting member from the second connecting member. In some examples, the second position includes the locking device being inserted at least partially into the blocking device.

The present invention provides a buckle lock includes a lock member and a buckle base which are able to be inserted and locked to each other. The buckle base includes a lock portion and a release button, and the lock portion includes at least one locking mechanism. It is characterized in that when the locking mechanism is in a locked state, the lock member can still be inserted into the buckle base and the lock connection is completed immediately after completing the locking action.

A safety belt buckle includes a base and a latch. The base includes a chamber with at least one positioning member disposed therein, and an opening communicating with the chamber. The latch includes a tongue with at least one recess with one open side, is adapted to be inserted into the chamber through the opening. The at least one positioning member is introduced into the at least one recess through the open side thereof to be engaged with the at least one recess when the tongue is inserted into the chamber. By the design mentioned above, the latch could be engaged with the positioning member of the base through the recess. Whereby, the latch still could be engaged with the base securely and would not be released easily and accidentally when any one of the latch and the base is laterally pushed or pulled.

A system and method for a locking mechanism that includes an ability to indicate proper engagement via a signal cable coupled through a harness. The locking mechanism may include electronic components including three magnetic actuators and corresponding electronic switches that signal change of state. Locking tabs and a leading edge of the insert respectively include the three magnetic actuators. The electronic switches, which may be magnetically activated reed switches, signal status change to an external controller and, optionally, an external computer. Further, status signals and power signals may be routed through a steel cable or woven nylon harness that coupled the locking mechanism to a local anchor point. Change of status notification may be important on critical safety worksites where lack of mechanical and electronic connection can be life threatening.

A seatbelt buckle that includes a housing, an attracting member, an attractable element, and a plate adapted to retain a seatbelt clip within the housing. The member, the element, and the plate may be carried by the housing. The buckle is adapted so that when the member is electronically actuated, the element causes the plate to move toward the member and thereby release the clip.

A harness buckle locking assembly for a buckle of for a car seat includes an On-Board Diagnostics (OBD) device, comprises a first transceiver and is configured to operationally engage an OBD II port of a vehicle, and a housing, which is positionable over a release button of a buckle of a car seat. A depressible button is attached to a pin and can be depressed to actuate the release button. A lock unit selectively locks the pin within the housing. An electronics unit is operationally engaged to the lock unit and communicates with the OBD device and with an electronic device of a user. The electronics unit can signal the user of occupancy of the car seat, when the vehicle has been turned off for a preset time, and also can selectively actuate the lock unit to unlock the pin.

A device and system that can be used to assist actuation of a buckle release is disclosed. A device can comprise a first arm and a second arm joined by a U-shaped connecting portion. The device can also comprise a button contact feature. The device can be inserted over a buckle with the button contact feature over a buckle release button, and the device used to assist engagement of the buckle release button by a person operating the device. A system can comprise a device and various additional features or accessories.

A seatbelt buckle that includes a housing, an attracting member, an attractable element, and a plate adapted to retain a seatbelt clip within the housing. The member, the element, and the plate may be carried by the housing. The buckle is adapted so that when the member is electronically actuated, the element causes the plate to move toward the member and thereby release the clip.

A seat buckle that accommodates different types and styles of child seats. The standard platform can be used across a variety of baby to child seats. The belt has a button on the front, with a safety mechanism on the back that must be articulated to enable activation of the belt buckle. The buckle may take the configuration of an adapter allows a parent to install the safety buckle for a child seat. Adapter on a pre-existing seat. The belt ideally configured for a Y style buckle where straps extend over each shoulder and a single strap passes between the legs of the child. This allows the safety to pass or be blocked between the two belt buckle components of the shoulder straps. This also accommodates most of the buckles that are being produced.

A buckle assembly includes a first buckle member having an insertion member, a second buckle member, a first buckle latch, a second buckle latch, a plurality of resilient elements, and a locking arrangement. The locking arrangement includes at least two locking protrusions and at least one guiding member. The locking protrusions are extended from one of the insertion member and the second buckle body, and are arranged to form a locking channel between the two locking protrusions. The guiding member is extended from the remaining one of the insertion member and the second buckle body, and is arranged to be inserted in the locking channel formed by the locking protrusions so as to retain the first buckle member to be locked with the second buckle member when the first buckle latch and the second buckle latch are in the locked position.
