The disclosure provides for a system that includes a seat mounted in a vehicle. The seat includes a base, a back support, a hinge, and a seat belt integrated into the seat. The back support is capable of rotating relative to the base and thereby reclining. The hinge is between the base and the back support and is configured to lock the back support in positions in relation to the base. The seat belt has a shoulder portion and a lap portion and is attached to the seat at a shoulder anchor in the back support and a base anchor in the base. When a generated torque, created from a forward force applied by the shoulder portion of the seat belt, exceeds a threshold amount of torque, the hinge is configured to unlock and back support is configured to rotate forward from a reclined position towards an upright position.

A motor vehicle and occupant seat combination may include any one or combination of means for selectively preventing forward pivoting of at least one vehicle seat, one or more web attenuators for dampen forces applied thereby by one or more respective shoulder webs of at least one occupant restraint system, at least one sleeve received on at least one shoulder web and a corresponding sleeve adjuster for adjusting a position of the sleeve along the respective shoulder web, and one or more ratcheting web retractors for selectively tightening a lap web or a thigh web about an occupant of at least one vehicle seat.

In this buckle device, a base end portion of a belt is folded back on itself to form a ring-shaped portion, and the belt is wound onto a spool in a state in which the ring-shaped portion of the belt has been inserted through an insertion hole in the spool. This enables a winding radius of the belt to be increased by the base end portion of the belt and enables a load at which the belt is permitted to be pulled out to be reduced, when the belt is pulled out from the spool.

In this buckle device, when a second wind of a belt is pulled out from a spool, a load at which the belt is permitted to be pulled out is small, whereas slide resistance of the belt with respect to a slide face is large. When a first wind of the belt is then pulled out from the spool, the belt pull-out permitting load is large, whereas the slide resistance of the belt with respect to the slide face is small. This enables variation in a load at which extending of a buckle body is permitted to be suppressed.

A seat belt system for a vehicle comprising a seat (16) that includes a seat frame (26) with a seat frame side part (28), a seat belt (18) associated with the seat (16) and having a webbing (40), and a belt tensioner associated with the seat belt (18). The seat frame side part (28) includes a lateral opening (36) facing the vehicle interior. The seat (16) includes a seat cross tube that opens into the vehicle interior via the opening (36). The belt tensioner is accommodated in the seat cross tube. The seat belt system further includes a belt guide (54) and a webbing deflector (56) for the webbing (40), the belt guide (54) being provided at the opening (36). Moreover, a vehicle comprising such a seat belt system is provided.
