A buckle tongue having a tongue body extending in an insertion direction and forms a belt slot that extends across the insertion direction and is provided for guiding a belt strap through it, and has a contact section in which the belt strap rests in a load position, and the contact section has several recesses that in the load position minimize slipping of the belt strap; and a blocking element movably arranged in the tongue body, wherein the strap can move through the belt slot in a pass-through position of the blocking element and is inhibited in its mobility by the blocking element in the load position by a tensile force introduced into the belt strap, wherein in the pass-through position, the blocking element is arranged between the strap and the contact section, so that the belt strap does not rest against the recesses in the pass-through position.

A safety belt latch assembly includes an adjusting section, a snap-fit piece, and a strap winding bar. The adjusting section is provided with an opening and two side plates. Each of the side plates of the adjusting section is provided with an elongate slot. The snap-fit piece has a first end provided with a torsion portion twisted from the adjusting section, with a torsion angle of ninety degrees (90°) being defined between the snap-fit piece and the adjusting section. The snap-fit piece has a second end provided with a fastening portion having a fastening hole. The strap winding bar is provided with two contact portions. Each of the contact portions of the strap winding bar is inserted into the elongate slot of one of the side plates of the adjusting section.

A harness system is provided and includes an upper buckle, an upper strap and a restraining assembly. The upper strap includes shoulder portion and a waist portion divided by the upper buckle. A through slot is formed on the upper buckle. The restraining assembly includes an anti-sliding structure, a beam structure disposed on the upper buckle and a stopping component. The through slot includes a first portion and a second portion divided by the beam structure and respectively adjacent to the shoulder portion and the waist portion. The upper strap passes through the first portion of the through slot from bottom to top and passes through the second portion of the through slot from top to bottom. The stopping component is detachably disposed on the shoulder portion and configured to abut against the upper buckle for restraining a sliding movement of the upper buckle relative to the upper strap.

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.

A harness system includes an upper buckle, an upper strap and a restraining assembly including an anti-sliding structure and a beam structure. A through slot is formed on the upper buckle. The upper strap passes through the through slot. The beam structure is slidably disposed on the upper buckle. The anti-sliding structure is disposed on at least one of the beam structure and a wall of the through slot. The upper strap is engaged by the anti-sliding structure for restraining a sliding movement of the upper buckle relative to the upper strap and toward a shoulder portion when the upper strap is forced to drive the beam structure to slide relative to the upper buckle and toward the wall of the through slot.

A harness system includes one or more harness assemblies. Each harness assembly includes a flexible restraint formed of a coated fabric. An adjuster is provided to adjust an effective length of the flexible restraint. The adjuster includes a frame, a restraint guide, and a cam.

Adjustable connectors disclosed herein are adapted to connect webbing, e.g., urethane coated webbing, to a buckle. The adjustable connector includes a baseplate, a tongue at a front end of the baseplate, a webbing aperture within the baseplate, and first and second walls extending perpendicularly from the baseplate. In certain embodiments, the adjustable connector includes a rotatable lock bar including a central portion having an outer surface and first and second tabs. In certain embodiments, a front edge of the webbing aperture comprises an arced front edge extending between side edges of the webbing aperture such that a distance between a center of the arced front edge of the webbing aperture and a back edge of the webbing aperture is greater than a respective distance between each of the ends of the arced front edge and the back edge of the webbing aperture.

Adjustable connectors disclosed herein are adapted to connect webbing to a buckle. The webbing can be, e.g., a urethane coated webbing, some other type of coated webbing, or a non-coated webbing. The adjustable connector includes a baseplate, a tongue at a front end of the baseplate, a webbing aperture within the baseplate, first and second walls extending perpendicularly from the baseplate, and first and second slots respectively within the first and second walls. In certain embodiments, the slots are tapered. In certain embodiments, the adjustable connector includes a rotatable lock bar including a central portion having an outer surface and first and second tabs. In certain embodiments, each of the tabs has a cross-section with a major-axis that is greater than a minor-axis that is orthogonal to the major-axis. In certain embodiments, a front edge of the webbing aperture comprises an arced front edge.
