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 child restraint, in accordance with the present disclosure, includes a juvenile seat and a child-restraint harness. The child-restraint harness may be configured to move to make it easier for a caregiver to seat and unseat a child.

A vehicle occupant protection device includes: a three-point seatbelt designed to be worn so as to cross the body of an occupant sitting in a seat of a vehicle; a force limiter that applies tension to the three-point seatbelt; an airbag device having an airbag designed to deploy in front of the upper body of the occupant sitting in the seat so as to support the upper body and head that are going to be thrown forward, the airbag having an upper-side portion, an outer-side portion, and an inner-side portion capable of deploying at different pressure levels; a controller that activates the force limiter and the airbag device upon a collision; and an occupant identification device that identifies the physique of the occupant sitting in the seat. The controller changes deployment of each portion of the airbag in accordance with the identified physique.

A vehicle seatbelt device includes: a three-point seatbelt, a tongue having a long hole through which an intermediate portion of the seatbelt is inserted, a buckle that has a buckle main body at which the tongue is anchored and a stay that extends from the buckle main body toward a vehicle lower side and is connected to the vehicle seat, a forward tilting mechanism that tilts the stay toward a seat front side at a time of a vehicle collision or at a time a vehicle collision is predicted, and a shoulder pretensioner that pulls in a shoulder belt of the seatbelt at a time of a vehicle collision, wherein a lower end portion of the buckle main body and an upper end portion of the stay are connected rotatably around an axis along a seat transverse direction.

A seat assembly includes a seat back and a headrest adjustably coupled to the seat back. The headrest defines a first guide passage and a second guide passage, each extending through the headrest. The seat assembly includes a retractor and a belt. The belt extends continuously from a first end to a second end. The first end is engaged with the retractor. The belt has a looped portion from the first guide passage to the second guide passage. The belt extends from the looped portion through the first guide passage to the first end, and extends from the looped portion through the second guide passage to the second end.

A vehicle seat belt system is provided. The vehicle seat belt system includes a seat belt comprising a tubular seat belt webbing defining a passageway and a plurality of pressure control valves and a seat belt buckle for connecting to the seat belt. The seat belt buckle has an air delivery port for delivering air to the passenger, and an air delivery device supplies air to the seat belt, wherein the valves allow the supplied air to exit the seat belt at a first air pressure and block air from exiting at a second pressure.

A torso equipment support system, for use with a seat bucket of an aviation or ground vehicle, providing upper torso and worn equipment support to an occupant. The system includes a base, a flexible column, a support beam, and a shoulder harness assembly. The shoulder harness assembly is coupled to the support beam and configured for releasable attachment with shoulder belts worn by the occupant. The shoulder harness assembly includes a yoke and a set of restraint shoulder straps. The yoke is slideably coupled to the support beam at a first vertically oriented portion and has a second portion that is split into two horizontally projecting members for extension over the shoulders of the occupant. The set of restraint shoulder straps project inwardly for extension over the shoulders of the occupant from at least one retractor, and extend to the horizontally projecting members.

A plus-two belt system is provided. The plus-two belt system is a supplement to a traditional three-point belt system. The plus-two belt system has a longitudinal webbing anchored at a first end and coiled on a retractor at a second end. When an occupant is sensed and the vehicle engine is on, a reminder chime can sound when a magnetic strip in the webbing of the plus-two belt system is detected. The magnetic strip can be detected with a Hall effect sensor and the Hall effect sensor can be located adjacent the retractor.

A restraint system includes a first member including a first hole and fixable to a seat frame, a second member including a second hole and slidably coupled to the first member between a retracted position in which the first and second holes are aligned and an extended position in which the first and second holes are spaced from each other, a buckle housing fixed to the second member, and a tongue including a third hole and insertable into the buckle housing to an inserted position in which the second and third holes are aligned.
