The present disclosure relates to a seatbelt arrangement for a vehicle which comprises a seatbelt and a plurality of connection points, wherein a fourth connecting point is placed at a first lateral side of a vehicle seat and at an upper portion of a backrest. The disclosure also relates to a vehicle comprising a seatbelt arrangement and also to corresponding methods.

There is disclosed an energy absorption device comprising a plurality of pillars mountable to a ceiling of a hull, each pillar having a fixed portion and a movable portion, the movable portion slidable relative to the fixed portion; a deformable material disposed between the fixed portion and movable portion such that the deformable material resist the sliding movement of the movable portion in one direction; the deformable material further adapted to permanently deform when a blast energy is directed towards the ceiling; and a seat assembly attached to the movable portion, the seat assembly adapted for an occupant.

Four-point seat belt comprising two thoracic branches configured to anchor the chest of a user to a backrest of a vehicular seat; two abdominal branches configured to girdle and anchor the waist of the user to the vehicular seat; at least one damping device configured to be activated upon exceeding a first predetermined value of a tension force imparted by the user to the belt; wherein the damping device is configured to cause, upon its activation, a controlled advancement of the chest of the user while limiting the acceleration of the head of the user.

A seat restraint system includes an over-the-shoulder (OTS) restraint and a lap restraint. The lap restraint includes a lap restraint enclosure defining an interior space and having an opening through the lap restraint enclosure, a track disposed in the interior space, and a movable assembly engaged with the track and configured to move along the track. The movable assembly includes an extension from the interior space, through the opening, and to an external space outside of the lap restraint enclosure. The movable assembly also includes engagement feature coupled to the extension and configured to be coupled to the OTS restraint in an engaged configuration.

A harness includes a primary locking mechanism, at least one strap of webbing coupled to a primary locking mechanism, and a secondary locking mechanism associated with the at least one strap of webbing. The secondary locking mechanism is located downstream from the primary locking mechanism and is movable to selectively contact the at least one strap of webbing to restrict movement of the at least one strap of webbing relative to the secondary locking mechanism.

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 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 vehicle seating arrangement includes first and second seating assemblies that are each equipped with a seat and a seatback. A surface of the seat of the first seating assembly is vertically above a surface of the seat of the second seating assembly. A forward extreme of the first seating assembly is displaced rearward of a forward extreme of the second seating assembly.

A system and method for securing a child in a typical adult-sized automobile seat are provided. The system includes a plurality of straps, or webbing, removably attached to the typical adult-sized automobile seat, an optional seat pad, two optional shoulder pads, two optional shoulder buckles, a chest buckle, and a hip buckle. The system is configured to safely and conveniently secure the child into the typical adult-sized automobile seat, thereby reducing or eliminating a need for a child-sized automobile seat. During use, the system secures the child into the typical adult-sized automobile seat, thereby preventing or ameliorating injury from an automobile collision.
