A seat belt device includes a webbing, a locking tongue, and a guide. The webbing includes a lap belt and a shoulder belt. The locking tongue is configured to undergo a change from a free state, in which the webbing is capable of passing between a side of the lap belt and a side of the shoulder belt, to a lock state, in which the webbing is not capable of passing between the side of the lap belt and the side of the shoulder belt, in accordance with a collision or a warning of the collision of a vehicle. The guide is configured to displace a location on the shoulder belt that is adjacent to the locking tongue in a direction away from the occupant in response to the change from the free state to the lock state.

A plug-in tongue for a seatbelt includes a plug-in tongue component (10) and a clamping member (12) mounted thereto, wherein a belt guide passage (30) is delimited between the plug-in tongue component (10) and the clamping member (12), and the clamping member (12) comprises a center part (18) and two lateral parts (20) extending from the two ends of the center part (18) transversely to the latter. The plug-in tongue is characterized in that the center part (18) includes a central guide surface (32) located between the two lateral parts (20), and the two lateral parts (20) include lateral guide surfaces (34) facing each other, the guide surfaces (32, 34) constituting limitations of the belt guide passage (30).

A seat belt device includes a webbing and a tongue. The webbing includes a lap belt and a shoulder belt. At least a portion of the lap belt is configured to be disposed to extend in a vehicle-width direction along a front of an abdomen of an occupant. At least a portion of the shoulder belt is configured to be disposed obliquely along a front of a chest of the occupant. The tongue is provided between the lap belt and the shoulder belt of the webbing and is configured to be coupled to a vehicle body when the tongue is to be mounted. The tongue rotates in accordance with a collision or a warning of the collision of a vehicle in a direction in which the shoulder belt is twisted with respect to the vehicle body.

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 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 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.

A seat adjustment assembly, and a seat and vehicle including same, are described. The seat adjustment assembly includes an assembly frame being adapted for connecting to a seat; at least one first roller rotatably connected to the at least one wall; and at least one second roller rotatably connected to the at least one wall, the assembly frame and the rollers defining a cavity, the at least one first roller being disposed generally above the cavity, the at least one second roller being disposed generally below the cavity, for each roller, when contact surfaces of the roller are in contact with a rail disposed in the cavity, the contact surfaces of the roller being offset from a lateral center of the roller, the roller and the rail defining a passage between the rail and the lateral center of the roller.

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.

The present invention relates to a deflector 1 for guiding a belt strap in a vehicle, at least comprising a metal body 2 having a fastening opening 3 attachable to the vehicle and having a belt slot 4, and an adapter 5 made of plastic and connected to the metal body 2, wherein the metal body 2 comprises a receptacle 6 and an engagement section 7 corresponding to the receptacle 6 is formed on the adapter 5 so that the engagement section 7 engages in the receptacle 6, and wherein the receptacle 6 has a receptacle inner surface 8 facing the engagement section 7 and the engagement section 7 has an engagement surface 9 facing the receptacle 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).
