Aspects of the disclosure relate to reducing the likelihood of injury to a passenger in a collision. In one example, a system for reducing the likelihood of a passenger submarining, may include a restraining device for restraining the passenger. A second restraining device for further restraining the passenger may also be included in the system. A locking mechanism may be configured to prevent a seat back from reclining when the second restraining device is not activated.

A restraint system includes a seatback and a waist restraint. The waist restraint includes a housing having a middle portion fixed to the seatback and two arms extending outwardly from the middle portion. The waist restraint includes an extension deployable from each arm to a deployed position. The extensions are engaged with each other in the deployed position. Each arm is hinged to the middle portion and is pivotable towards the other arm.

A multi-point seat belt system is applied to a seat of a vehicle and has a webbing locking device, an emergency locking-retracting mechanism, and two automatic locking retractors. The webbing locking device has a buckle assembly and a tongue assembly detachably disposed on the buckle assembly. The emergency locking-retracting mechanism is disposed on the seat and has two shoulder webbings connected to the buckle assembly and the tongue assembly respectively. The two automatic locking retractors are disposed on two sides of the seat and have two lower webbings connected to the buckle assembly and the tongue assembly respectively. The two shoulder webbings locked by the two emergency locking retractors and the two lower webbings tightened by the two automatic locking retractors are distributed around the body of the occupant and can fasten the occupant on the seat steadily for promoting the safety protection performance.

A motor vehicle belt restraint system combining a three-point active seatbelt system with a two-point seatbelt system. The webbing of the three-point seatbelt is allowed to slide through a latch plate releasably attached to a seatbelt buckle. The webbing of the two-point belt system is affixed to the latch plate. When in use, the belt systems combine to provide two lap belt segments extending across the lower torso of a vehicle seat occupant with a single diagonal shoulder belt section. Additional embodiments incorporate the use of an anchor mechanism for the three-point belt system having additional capabilities including a webbing release and a load limiting function. Further embodiments provide different arrangements for the two lap belt sections.

A modular vehicle seat is disclosed that includes one or more safety measures incorporated into the seat such that the seat can be pre-assembled in a modular unit that can be incorporated into a variety of vehicle designs. The safety measures may include an airbag deployment system that deploys an airbag from a seat back and extends around a shoulder portion of the occupant restraint system. The airbag deployment system includes an airbag that extends coaxially around the shoulder web of the restraint system of the vehicle seat. The safety measures may include a device for pre-tensioning a lap portion of an occupant restraint harness coupled to a seat portion of the vehicle seat. Illustratively, the pre-tensioning device may be activated just prior to activation of the airbag deployment system.

A restraint system includes a seat defining a centerline and including a seat bottom and a seatback. A pair of upper retractors are disposed on the seatback, a pair of lower retractors are disposed on the seat bottom, and a pair of middle retractors are disposed on the seat between the pairs of upper and lower retractors. Each pair of retractors includes one retractor disposed on each side of the centerline.

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 restraint system includes a seatback and a waist restraint. The waist restraint includes a housing having a middle portion fixed to the seatback and two arms extending outwardly from the middle portion. The waist restraint includes an extension deployable from each arm to a deployed position. The extensions are engaged with each other in the deployed position. Each arm is hinged to the middle portion and is pivotable towards the other arm.

A seat assembly for a vehicle includes a seat, and a first seatbelt having a first end and a second end. The first end of the first seatbelt is coupled to the seat. The seat assembly includes a latch plate and a second seatbelt. The latch plate is fixed to the second end of the first seatbelt, and the second seatbelt is slideably coupled to the latch plate. The first seatbelt and the second seatbelt increase lateral support of the occupant during, e.g., a rollover event, oblique or side impacts.
