A safety belt buckle assembly includes a base, two combination pieces, and a locking member. The base has a mounting section, a belt passage section, a receiving slot, a connecting portion, and an insertion opening. The combination pieces are located at two sides of the receiving slot. Each of the combination pieces has a shaft receiving groove and an insertion hole. A shaft is mounted in the shaft receiving groove of each of the combination pieces and extends through a shaft hole of the locking member. Each of the combination pieces is provided with a resting member, an elastic member, and a covering member mounted in the insertion hole respectively. The locking member is pivotally mounted on the base and has a locking portion locked by the resting member of each of the combination pieces.

Multiple-utility release buckles used in passive restraint systems for human occupants of vehicles. These types of buckles are typically useful in one embodiment, as a buckle for a safety harness that is commonly used in racing gear, such as automobile racing.

A lever-controllable magnetic buckle includes a male member having a male engaging section, a female member having a female engaging section formed with two groups of female guide-out surface, and a control lever. The male member is magnetically attracted for moving to the female member with the male engaging section retained to the female engaging section. The control lever is pivotally connected to the male member and has an actuating cam contacting with the female member. The female member will contact with surfaces of the actuating cam at different positions thereof when the control lever is pivotally swung relative to the male member, allowing the male engaging section to disengage from the female engaging section. Then, the control lever can be further swung to move the male member in different directions to selectively contact with one of the two groups of female guide-out surface and be completely separated from the female member.

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.

Seat belts, seat belt assemblies, seat belt systems, and methods for incorporating the seat belts, seat belt assemblies, and seat belt assembly systems are disclosed, with the seat belt including a seat belt locking mechanism sensor that, in tandem with a seat belt thermal sensor provides confirmatory information as to a definitive locking condition or locking state of a seat belt.

The present invention relates to a belt buckle (10) for a length-adjustable aircraft safety belt, wherein the belt buckle (10) comprises: a main body (12) which defines a receiving space (20); a holder (14) for attaching a belt strap (16) of an aircraft safety belt; and a locking device (18) for latching a buckle tongue on the main body (12) for closing the aircraft safety belt,
wherein the main body (12) comprises a base plate (40) and side cheeks (42) projecting therefrom at two opposite sides, wherein the base plate (40) forms a substantially plane base surface (44), and
wherein the holder (14) is mounted on the side cheeks (42) in a movable manner and a clamping edge (38) of the base plate (40) facing the holder (14) projects from the base surface (44) in the direction of the holder (14), so that the holder (14) is drawn to the clamping edge (38) when a tensile load is applied to the belt strap (16) and the belt strap (16) is clamped between the clamping edge (38) and the holder (14), so that a length change of the aircraft safety belt is blocked.

Seat belts, seat belt assemblies, seat belt systems, and methods for incorporating the seat belts, seat belt assemblies, and seat belt assembly systems are disclosed, with the seat belt including a seat belt locking mechanism sensor that, in tandem with a seat belt thermal sensor provides confirmatory information as to a definitive locking condition or locking state of a seat belt.

A buckle has a main buckle body having a first side wall, a second side wall, and at least one first slot for receiving a strap, and a top bar connected to the main buckle body at the first side wall and forming a second slot with the main buckle body for receiving a second strap. The second slot is open at a distal end thereof. The top bar has a guide track extending longitudinally therethrough, with the guide track opening into the second slot. A catch is formed on the second side wall adjacent the distal end of the second slot. A spring gate is disposed in the guide track. The spring gate is placed around the catch to close the distal end of the second slot. The spring gate is releasable from the catch by pressing on the top bar until the spring gate clears the catch.
