Passenger safety belt buckles are disclosed. In embodiments, a safety belt buckle includes a base member and a release member coupled to the base member. The release member is configured to release a tongue held between the release member and the base member when the release member is pulled away from the base member. In an example embodiment, the release member is formed by a plurality of printed device layers and a metal coating disposed over the plurality of printed device layers. In another example embodiment, the release member is formed by a plurality of printed metal layers. In yet another example embodiment, the release member includes a recess with an in-mold feature disposed within the recess.

A safety belt latch structure includes a base, a locking hook member, a positioning shaft, and a press switch. The locking hook member is provided with a first locking portion. The press switch includes a push knob, a covering member, and an elastic member. The push knob has a pressing portion, a resting portion, a depression, and a second locking portion. The first locking portion is locked with the second locking portion, and received in the depression. Thus, the user only needs to press the push knob to unlock the locking hook member and to release the safety belt latch structure, such that the safety belt is released quickly. In addition, the press switch is surrounded by the base, such that the push knob will not be contacted due to impact, thereby preventing the locking hook member from being unlocked from the press switch.

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.

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.

Passenger safety belt buckles are disclosed. In embodiments, a safety belt buckle includes a base member and a release member coupled to the base member. The release member is configured to release a tongue held between the release member and the base member when the release member is pulled away from the base member. In an example embodiment, the release member is formed by a plurality of printed device layers and a metal coating disposed over the plurality of printed device layers. In another example embodiment, the release member is formed by a plurality of printed metal layers. In yet another example embodiment, the release member includes a recess with an in-mold feature disposed within the recess.

The present application includes embodiments for a belt adjustment system. The belt adjustment system can be configured to engage a belt comprising a plurality of belt teeth. The belt engagement system can include a buckle portion that includes a belt clamp configured to couple the belt to the buckle, a lever pivotally movable between a first position and a second position, and a belt-engaging tab, the tooth-engaging tab positionable between a tooth-engaging position and a tooth-disengaging position responsive to the position of the lever on. The belt adjustment system can include a tool housing having a first wall and a second wall that form a slot. A tool comprising a distal end and a proximal end can be coupled to the tool housing, the tool positionable within the slot between a closed position and an open position.

A connection arrangement for use with a wearable body harness has a first connector with a first fixed buckle configured to connect to a first portion of a first shoulder strap of the harness, and a first adjustable buckle configured to connect to a second portion of the first shoulder strap. The connection arrangement further has a second connector removably connectable to the first connector. The second connector has a second fixed buckle configured to connect to a first portion of a second shoulder strap of the harness, and a second adjustable buckle configured to connect to a second portion of the second shoulder strap. Each of the first adjustable buckle and the second adjustable buckle has an adjustment mechanism configured for adjusting a length of the second portion of the first and second shoulder straps by selective frictional engagement with the second portion of the first and second shoulder straps.

A buckle assembly including a first portion, a second portion, an actuator and a lever. The first portion includes a hollow body, an open top, a locking slot extending through the hollow body and a fulcrum. A second portion of the buckle includes a base opposite of a locking leg, the locking leg including a cavity, and a channel. Inserting the second portion into the hollow body through the open top of the first portion causes the locking leg to engage the locking slot and to lock the first portion to the second portion. An actuator slideably engaged to the channel and includes an arm slideably connected to the cavity. Applying a force to the actuator causes the arm to withdraw the locking leg, disengaging the locking leg from the locking slot. A lever is mounted on the fulcrum to apply the force to the actuator when the lever is pulled.

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.
