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.

A tongue (7) includes a plate (20) having a longitudinal portion (21) that is insertable into a buckle (8), and a broader portion (22) that is located on an opposite side from a tip end (24) of the longitudinal portion (21) and is formed wider than the longitudinal portion (21). The broader portion (22) is covered at least in part. The broader portion (22) has a base (23) that is connected to the longitudinal portion (21), a beam (25) that extends in a long-side direction of the broader portion (22), a connecting portion (39) that connects the base (23) to the beam (25), and a through hole (71) that is defined by the base (23), the beam (25), and the connecting portion (39) and through which a seat belt is inserted. An edge, located at the side portion (35, 36) of the beam (25) forming the through hole (71), is subjected to a beveling press or is chamfered. The edge faces one side of the seat belt (4) passing through the through hole to a shoulder anchor (6).

The invention relates to a belt deflector with a main element (100) that can be attached to the structure of a vehicle, and with a belt support element (200) that is movable relative to the main element (100) and forms a support surface (231) or support edge for a safety belt (20) to be deflected.

According to the invention, the belt deflector comprises an intermediate element (300, 400) that is deformed when the movable belt support element (200) is moved relative to the main element (100), in the direction of the intermediate element (300, 400), and because of this deformation is pressed against the safety belt (20).

A tongue mechanism for use in an occupant restraint system also having a buckle mechanism and a webbing. The tongue mechanism includes a tongue member configured to selectively engage the buckle mechanism, a body formed over a portion of the tongue member, a slider, and a biasing member configured to laterally bias the slider. The body includes a body contact surface. The slider includes a slider contact surface and is configured to travel along a track between a first free position and a second locking position. When the slider is positioned in the first free position the tongue mechanism is free to slide along the length of the webbing, and when the slider is positioned in the second locking position a portion of the webbing is clamped between the slider contact surface and the body contact surface thereby preventing the tongue mechanism from sliding along the length of the webbing.

A webbing-buckling device of a multi-point seat belt system has a buckle assembly and a tongue assembly. The buckle assembly has a buckle base having a first frame portion and a webbing-locking member slidably inserted through the first frame portion. The tongue assembly is disposed on the buckle assembly and has a tongue base having a second frame portion and a webbing-fixing member slidably inserted through the second frame portion. One of two webbings is inserted between the first frame portion and the webbing-locking member, and the other webbing is inserted between the second frame portion and the webbing-fixing member. Alternatively, the webbing-buckling device has a buckle assembly and two tongue assemblies disposed on the buckle assembly. Each tongue assembly has a tongue base having a second frame portion and a webbing-fixing member inserted through the second frame portion. The webbings are inserted through the tongue assemblies.

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 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.

An extension unit includes a buckle member, a first coupling member, a second coupling member, and a webbing belt. The buckle member is engaged with a first tongue plate of a seat belt apparatus, includes a first holder holding the webbing belt, and a fixing member fixing an end of the webbing belt. The second coupling member is disposed between the buckle member and the first coupling member and coupled to the first coupling member. The webbing belt joins the buckle member and the first coupling member. The second coupling member is so disposed that a projected region extending inward in a vehicle width direction is defined. The projected region has a size corresponding to a thickness of an operator's hand and is not overlapped with the buckle member. The second coupling member includes a second holder holding the webbing belt extending from the first holder to the fixing member.

A seatbelt latch plate assembly includes a latch plate, a D-ring, and a pivot stop. The D-ring is pivotably connected to the latch plate. The pivot stop is disposed between and rotatably fixes the latch plate to the D-ring. The pivot stop includes a deformable element. The deformable element is deformable at a predetermined pivot torque between the D-ring and the plate.

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.
