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 assembly that includes a tongue assembly having a weblock mounted to a tongue selectively securable to a buckle; a webbing extends through the weblock between a torso portion and a lap portion; and with the weblock allowing for the webbing to slide between the torso and lap portions when in an unlocked position and pivoting relative to the tongue when in a locked position to reorient the torso portion extending from the tongue.

A buckle assembly includes a female buckle body that interchangeably mates with either one of a male buckle body or a retainer ring defining a leading bar. The female buckle body has a receptacle to receive an extension portion of the male buckle body slidable therein. A biased lever body is pivotally supported on the female buckle body for cooperating with a catch on the male buckle body between a blocking position retaining the extension portion in the receptacle and a released position allowing removal of the extension portion. The female buckle body also has a slot aligned with the receptacle to receive the leading bar of the retainer ring therein so that the lever body can also selectively retain the retainer ring mated with the female buckle body.

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 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.

At a present tongue, a vertical rib is provided between a first elastic piece and a second elastic piece of a cover. When a guide bar is displaced toward a vehicle rear side, and the guide bar abuts the first elastic piece and the second elastic piece, the guide bar abuts the vertical rib. Due thereto, imparting of load to the first elastic piece and the second elastic piece by the guide bar can be suppressed, and elastic deformation of the first elastic piece and the second elastic piece can be suppressed.

A seatbelt assembly and method of operating a seatbelt includes allowing webbing to slide between a lap portion and a torso portion through an unlocked weblock of a tongue assembly; and upon forces exerted by an occupant on the webbing, the weblock locking the webbing from movement between the lap and torso portions while increasing tension in the lap portion via the tongue assembly.

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 seatbelt assembly and method of operating that includes a tongue assembly having a weblock and a secondary weblock mounted to a tongue selectively securable to a buckle; a webbing extending adjacent to the weblock and secondary weblock between a torso portion and a lap portion; and the weblock and secondary weblock allowing for the webbing to slide between the torso and lap portions when in unlocked positions and pivoting relative to the tongue such that the weblock and secondary weblock prevent the webbing from sliding between lap and torso portions in locked positions.

A seat belt assembly including a seat belt webbing, a buckle, and a connector tongue assembly. The tongue assembly includes a body, a slot in the body for receiving a seat belt webbing, a locking mechanism located proximate the slot, and a spring biasing the locking mechanism towards the slot to frictionally engage the webbing to prevent freefall of the assembly.
