The present invention relates to a safety belt buckle, and more specifically, to a safety belt buckle which can stably detect whether a driver's safety belt is fastened even when foreign materials or water is introduced into the buckle in the case of being fastened with a tongue of a safety belt. In the safety belt buckle according to the present invention, a switch that detects whether a tongue of a safety belt is fastened is blocked from coming into direct contact with water or foreign materials, which are introduced from the outside, so as to stably detect fastening or unfastening of the tongue of the safety belt, and thus the safety belt buckle can be stably operated even when mounted in a seat exposed to the outside such as a seat of a forklift or a tractor.

A closure device for releasably connecting two parts with each other includes a first closure member having a rigid first locking protrusion and a second closure member which is attachable to the first closure member and in a closed position is held on the first closure member. The second closure member has a rigid second locking protrusion. The second locking protrusion can be brought into engagement with the first locking protrusion in an engagement direction and in the closed position engages the first locking protrusion in a positive locking manner. The first closure member includes a first magnetic member and the second closure member includes a second magnetic member, the first magnetic member and the second magnetic member being constituted to magnetically attract each other when the second closure member is attached to the first closure member for closing the closure device.

A buckle assembly includes a frame, a latch plate, and a tongue. The frame includes a latch opening and a slot for receiving the tongue. The latch plate is configured to be linearly displaced within the frame between a locked position and an unlocked position and includes a latch portion. The tongue includes a tongue opening having an angled leading end. When the tongue is inserted into the frame slot, the latch plate is biased to the locked position such that the latch portion of the latch plate traverses the angled leading end of the tongue opening until the angled leading end of the latch portion of the latch plate is secured in the latch opening in the locked position. In preferred embodiments, the buckle assembly includes a seat belt connected to the tongue for securing a user to a seat of a vehicle.

A seatbelt buckle device includes a housing, a frame, a latching arrangement and a release button. The frame includes a bottom wall and first and second laterally spaced walls. The latching arrangement selectively retains a latch plate within the housing. The release button is movable between a latched position and an unlatched position. A proximal end, a distal end and first and second laterally spaced apart legs of the release button cooperate to define an opening into which a projecting portion distally from the proximal end. At least one shield member laterally extends from the projection portion toward the first and second laterally spaced apart legs. Each shield member includes an outboard side spaced from an adjacent leg of the first and second legs by a gap. Each gap slidingly receives one of the first and second laterally spaced walls of the frame.

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 buckle assembly includes a buckle member that is configured to removably connect to a reciprocal buckle member. A retaining guard couples to the buckle member. The retaining guard is configured to reduce a potential of pinching as the buckle member connects to and disconnects from the reciprocal buckle member by providing a barrier where the buckle member and reciprocal buckle member connect.

A harness system with a buckle restraining function includes an upper buckle, an upper strap and a restraining assembly. The upper strap slidably passes through the upper buckle, and the upper strap includes a shoulder portion and a waist portion divided by the upper buckle. The restraining assembly utilizes an anti-sliding structure having a higher coefficient of friction to engage with the upper strap and further utilizes a stopping component to abut against the upper buckle. Therefore, the present invention can effectively restrain a sliding movement of the upper buckle relative to the upper strap and toward the shoulder portion by engagement of the anti-sliding structure and the upper strap and abutment of the stopping component and the upper buckle, which prevents an excessive decrease of a length of the shoulder portion of the upper strap and prevents a potential risk of injury of the passenger's upper body.

A locking device 1 includes a main body 2, a locking member 3 for locking a tongue 200, a lock releasing operation member 22 operated for releasing the lock of the tongue 200, a tongue guiding and discharging member 41 slid along an insertion direction of the tongue 200 in the main body 2 to guide the tongue 200 until the locking member 3 locks the tongue 200 and discharge the tongue 200 from the main body 2 when the lock of the tongue 200 is released, a power generator 5 having an operation member 53 pushed by the tongue guiding and discharging member 41 and pivotally moved in a plane parallel to the insertion direction of the tongue 200 when the tongue 200 is inserted into the main body 2 and generating electric power by utilizing external force applied through the operation member 53 and a wireless transmitting part 7 driven by the electric power generated by the power generator 5.

A safety harness comprises at least one strap, at least one attachment member for connecting the safety harness and a system for closing and adjusting the strap provided with a stationary fastening buckle secured to a first strand of the strap and a movable fastening buckle secured in such a way as to be adjustable along a second strand of the strap. The movable fastening buckle can cooperate with the stationary fastening buckle in an interlocking configuration in which the strap is closed on itself so as to form a closed loop having a perimeter that can be adjusted by adjusting the position occupied by the movable fastening buckle along the second stand. The safety harness comprises a locking part separate from the stationary and movable fastening buckles, secured to the first strand or the second strand of the strap and capable of varying between an active state urging the two, stationary and movable, fastening buckles relative to each other so as to positively immobilise the stationary and movable fastening buckles in the interlocking configuration, and an inactive state in which the two, stationary and movable, fastening buckles can freely adopt and come out of the interlocking configuration.

A stored energy release comprises an actuatable member slidably received within a housing. The actuatable member has an extended orientation wherein a portion of the actuatable member extends outwardly from the housing and a retracted orientation wherein the actuatable member resides within the housing. A biasing member is located between the actuatable member and the housing biases the actuatable member to the retracted orientation. A shaft is within the housing with the actuatable member configured for sliding movement along the shaft. A retaining member is located between the actuatable member and the shaft. The retaining member maintains the actuatable member in the extended orientation whereby potential energy is stored within the biasing member. A piezoelectric element selectively engages the retaining member to disable the retaining member and release the stored potential energy within the biasing member to place the actuatable member in the retracted orientation.
