A pretensioning lapbelt apparatus where the pretensioning of the lapbelt is performed by the rapid inflation of an airbag that is integral to the lapbelt itself. The design of the airbag, including the attachment locations of the ends of the webbing are chosen such that, upon inflation of the airbag, the free end of the webbing—the end of the webbing that is passed through the cinching latch—is pulled taught, thereby reducing the effective length of the lapbelt. The anchor is designed to be a cinching anchor such that once the airbag deploys and pulls the webbing through the anchor (thereby pretensioning the lapbelt) a sliding pin in the anchor “cinches” the webbing, effectively locking the webbing in the pretensioned state.

A seat belt for an occupant sitting on a seat in a vehicle includes a tongue part provided at a first side portion of the seat and a buckle part provided at a second side portion of the seat. The tongue part includes at least one first guide part that is operable between extended and contracted configurations, and at least one first webbing with a tongue wound therein. In addition, the tongue of the first webbing is connected with an end portion of the first guide part. The buckle part includes a second guide part that is operable between extended and contracted configurations, and the second webbing with a buckle wound therein. In addition, the buckle of the second webbing is connected with an end portion of the second guide part. The tongue of the tongue part is fastened to the buckle of the buckle part.

A seat belt system for a vehicle comprises a first seat belt buckle mounted at a first location, a second seat belt buckle mounted at a second location and a seat belt retractor mounted at a third location, a seat belt and a circuit. The third location is spaced along a seat for an occupant from the second location. The seat belt is extendable from the seat belt retractor and has a tongue. The seat belt is extendable to connect the tongue to the first seat belt buckle or the second seat belt buckle. The circuit interconnects the first seat belt buckle, the second seat belt buckle and the seat belt retractor. The circuit is configured to change an operating mode of the seat belt retractor when (1) the seat belt tongue is removed from the first seat belt buckle and/or (2) the seat belt tongue is removed from the second seat belt buckle. An optional indicator can be provided to indicate to the vehicle operator that the operating mode of the retractor has been changed.

A vehicle seat includes a seatback, a seat cushion, and a wheelchair fixing device. The seat cushion is switchable to a tip-up state where the seat cushion has been tipped up so as to extend along the seatback. The seat cushion includes a seating surface and a rear surface that is on the opposite side of the seat cushion from the seating surface. The wheelchair fixing device is provided on the rear surface-side. The wheelchair fixing device is configured to fix a wheelchair to the seat cushion.

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.

Device cooperating with a vehicle safety belt, designed for passenger transport, especially children consists of a tensioning belt (1) fixed releasably between the shoulder part (2) and the lap part (3) of the fastened safety belt. Tensioning belt is equipped with the length and tension controller (R) and has tunnels (9) on both ends formed by the rolled up and fixed ends of the belt. In the tunnels (9) there are arms of the snap fasteners (4) fixed to the fastened safety belt. Controller (R) includes a staple (7) fixing the length of the tensioning, belt (1) and a staple (8) blocking its position, and the tensioning belt (1) is composed of a fragment (1′) connected permanently with the fixing staple and a fragment (1″) connected slidingly with the fixing staple (7) and the staple (8) blocking the position of the belt (1).

A webbing height adjustment device is applied to connect to a webbing of a seat belt system. The webbing height adjustment device has a top ring member, a locking assembly, and a positioning member. The locking assembly is moveably disposed outside the top ring member. The positioning member is disposed on the side surface of the top ring member, is clutched with the locking assembly, and has a positioning element and a combining portion. The positioning element is disposed on the top ring member. The combining portion is disposed on the positioning element and selectively holds the locking assembly for positioning. The webbing height adjustment device is easy to operate and automatically locks the webbing. The webbing height adjustment device can be adjusted continuously and occupies little space when not in use.

A vehicle seat belt system includes a retractable seat belt buckle, one or more buckle sensors, and a control unit. The control unit is communicatively coupled to the one or more buckle sensors and one or more drive systems of a vehicle. The retractable seat belt buckle is movable between an extended position and a retracted position. The one or more buckle sensors are positioned to sense a position of the retractable seat belt buckle and output a signal indicative of the position of the retractable seat belt buckle. The control unit receives the signal from the one or more buckle sensors, determines the position of the retractable seat belt buckle based on the signal from the one or more buckle sensors, and transmits a stop signal to the one or more vehicle drive systems to cause the one or more vehicle drive systems to prevent motion of the vehicle when the retractable seat belt buckle is positioned in the extended position.

A pretensioning lapbelt apparatus where the pretensioning of the lapbelt is performed by the rapid inflation of an airbag that is integral to the lapbelt itself. A preferred embodiment of the pretensioning lapbelt apparatus would include a length of seatbelt webbing with a latch fixed on one end and a cinching anchor slidable on the opposite end. Integral to the lapbelt and attached to each end of the webbing is an airbag. The airbag, as is known in the art, is configured to be flat and folded in a compact uninflated state, and then quickly inflate to its inflated state upon the introduction of an inflation gas triggered by a crash event. The design of the airbag, including the attachment locations of the ends of the webbing are chosen such that, upon inflation of the airbag, the free end of the webbing—the end of the webbing that is passed through the cinching latch—is pulled taught, thereby reducing the effective length of the lapbelt (the length between the latch and the cinching anchor). The anchor is designed to be a cinching anchor such that once the airbag deploys and pulls the webbing through the anchor (thereby pretensioning the lapbelt) a sliding pin in the anchor “cinches” the webbing, effectively locking the webbing in the pretensioned state.
