A buckle assembly includes a first buckle, a second buckle, an operating portion, a locking component and a resilient portion. The first buckle includes an inserting end whereon an engaging portion is formed. An installation slot is formed on the second buckle for receiving the inserting end. The operating portion is disposed on the second buckle, and the locking component is fixedly connected to the operating portion. The locking component can be locked with or released from the engaging portion. The resilient portion is biased to separate the inserting end from the installation slot. The operating portion is operated to drive the locking component to release from the engaging portion. The inserting end can be separated from the installation slot by the resilient portion, so as to unlock the first buckle and the second buckle. The buckle assembly has advantages of easy operation and simplified structure.

A multi-point seat belt assembly has a buckle assembly, two webbing-locking mechanisms, two main webbings, and at least one retractor. The buckle assembly has a buckle member and a tongue member detachably inserted into the buckle member. The webbing-locking mechanisms are mounted on the buckle assembly, and each webbing-locking mechanism has a connecting member and a movable member mounted moveably on the connecting member. The connecting members of the two webbing-locking mechanisms are connected respectively with the buckle member and the tongue member. The main webbings are mounted respectively through the webbing-locking mechanisms and each main webbing has an end. The at least one retractor is connected with the ends of the two main webbings.

A vehicle seat belt assembly that ensures proper lap belt and shoulder belt restraint even when an occupant substantially reclines his or her seat. A primary shoulder belt that runs from a buckle member across the chest and shoulder of the occupant and engages a routing device and/or retraction/tensioning device coupled to a pillar, such as a B-pillar, of the body of the vehicle is coupled with a substantially coincident secondary shoulder belt that also runs from the buckle member across the chest and (same) shoulder of the occupant and engages a secondary routing device and/or secondary retraction/tensioning device coupled to a top portion of the seat back, adjacent to the heat rest of the seat and head of the occupant, on the same side of the seat as an anchor point associated with the lap belt.

A vehicle seatbelt assembly includes a load limiter having a seatbelt attachment portion and a seatbelt tension control mechanism that is configured to increase the length of a shoulder portion of a seatbelt in response to rapid or sudden deceleration of a vehicle, thereby reducing a level of tension experience by a seatbelt.

The invention relates to a belt deflector (10) having a main element (20) which is fastenable to a vehicle structure, and a belt contact element (30) which is movable in relation to the main element (20) and forms a belt contact face (SA30) or belt contact edge for a seat belt (40) that is to be deflected, wherein the belt deflector (10) has a deformable intermediate element (50) which, during a relative movement of the movable belt contact element (30) relative to the main element (20) in the direction of the intermediate element (50), is deformed and is pressed against the seat belt (40) by this deformation.

According to the invention, provision is made that the belt contact element (30) forms a mating clamping face (G30), and a belt strap portion (41) of the seat belt (40) is arranged between the intermediate element (50) and the mating clamping face (G30), and, during said relative movement, the intermediate element (50) presses the belt strap portion (41) onto the mating clamping face (G30).

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.

An airbag apparatus includes a longitudinal webbing guide configured to guide movement in a longitudinal direction of webbing, an inflatable airbag disposed along an outer side of the webbing guide, a bag cover configured to cover the airbag, and an upper side coupling member configured to couple a guide upper end of the webbing guide to a cover upper end of the bag cover, and move upward along the webbing together with the airbag when the airbag is inflated and deployed. A seatbelt apparatus includes the airbag apparatus.

A seat belt buckle tongue (1) with a tongue body (3) extending in the direction of plug-in (2), in which a strap slot (4) is formed for the passage of a strap (5), and a deflection element (6) movably the tongue body (3), The strap (5), in an unloaded passage position of the deflection element (6), is movable through the strap slot (4), and is at least prevented from moving by the deflection element (6) in the loading position of the deflection element (6) induced by a tensile force to the strap (5). The deflection element (6) is movable from the passage position into the loading position with a constriction portion (18) along the contact surface (19) of the tongue body (3), so that the strap (5) in the loading position with a strap portion is flat in contact with both the contact surface (19) of the tongue body (3) and with the constriction portion (18) of the deflection element (6). In the loading position, the tongue body (3) engages with a region having the contact surface (19), through at least the portion of the deflection element (6).
