In a lift-up buckle device, a worm wheel is engaged with a screw drive. When a worm is rotated in a forward direction and causes the screw drive to move downward, the worm moves the worm wheel downward. On the other hand, when the worm is rotated in a reverse direction and causes the screw drive to move upward, the worm moves the worm wheel upward. Consequently, the worm wheel may be stably engaged with the screw drive, and the worm wheel and worm may be stably mated.

A belt buckle feeder comprises a stationary base (12) adapted to be fixedly mounted to the vehicle and a carriage (14) movable to a retracted position and to an extended position vis--vis the base (12), which carriage is connected to a belt buckle (20) via an intermediate plate (22) provided between the belt buckle (20) and the carriage (14). The intermediate plate (22) is tightly connected to the belt buckle (20) and there is provided a positive guidance by which the intermediate plate (22) is pivoted during traversing to the extended position by a predetermined degree vis--vis the carriage (14) so that in addition to the traversing movement of the carriage (14) along a tilting direction (N) the belt buckle (20) reversibly tilts from a home position to an inclined position.

Provided is a belt assist device having a compact configuration and being configured to move a seatbelt to an easily reachable position. A vehicle seat includes a belt assist device attached to a lateral portion of a seat back and configured to move a portion of a seatbelt placed on the lateral portion to the easily reachable position. The belt assist device includes a rotary member attached to a recessed housing portion of the lateral portion via a rotary shaft and configured to rotate up and down between a housing position at which the rotary member is housed in the seat back and a protruding position at which the rotary member rotates to protrude forward of the seat back to push out a portion of the seatbelt. The rotary member is disposed forward of a belt guide provided at the periphery of an upper end of the seat back.

An adjusting device for a safety belt in a vehicle comprises at least one extendable belt guiding element which is provided for guiding a portion of the safety belt and at least one supporting element which is connected to the belt guiding element and which is able to be at least partially extended together with the belt guiding element. The belt guiding element is able to be extended from a resting position in a direction of extension in order to facilitate the grasping of the safety belt by a vehicle occupant when fastening the safety belt. The supporting element is flexible but in the extended state of the belt guiding element is sufficiently rigid at least in one portion transversely to the direction of extension such that the belt guiding element is held in an extended position via the now rigid portion of the supporting element.
