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, in accordance with the collision or the warning of the collision of the vehicle, displace a location on the shoulder belt that is adjacent to the locking tongue in a direction away from the occupant before the change to the lock state is completed.

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.

Seatbelt assemblies for motor vehicle occupant restraint providing enhanced frontal impact restraint characteristics. Embodiments illustrated a displacement of the intersection positioned between the lap and shoulder belt portions of an active three-point type belt system. In one set of embodiments particularly useful with dual retractor systems, adaptive positioning provisions allow the point of intersection to initially occur at or near the seatbelt latch plate and when a restraint load occurs components release to allow repositioning of the intersection. In other embodiments best implemented in single retractor systems, a turning loop is provided which displaces the webbing slot separating the lap and shoulder belt sections from the buckle latch plate.

A vehicle occupant restraint system includes an occupant seat, three-point seatbelt device, and an airbag module mounted to the seat. The three-point seatbelt device has a webbing that is configured to, when the occupant is seated on the seat, extend from an upper side in a vicinity of the occupant's outboard shoulder to a lower side in a vicinity of an inboard side of the occupant's waist and obliquely across the occupant's upper body so as to restrain the upper body. The airbag module has an airbag cushion and an inflator for providing inflation gas for the airbag cushion. In a crash event the airbag cushion inflates and deploys from the seat in a vicinity of the occupant's inboard shoulder obliquely across the occupant's upper body, and in a fully deployed state the airbag cushion directly connects to the webbing extended across the occupant's upper body.

A passenger state modulation system for passenger vehicles is presented. The passenger state modulation system operates to predict events that will impact the passengers state (e.g., motion sickness) before they happen and use the prediction to implement preemptive interventions with active vehicle sub-systems.

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 seat and safety assembly includes a seat cushion, a seatback, and a wraparound seatbelt system to restrain an occupant in rear, side and rollover crashes. The seat cushion is connected to a vehicle floor. The seatback is connected to the seat cushion. The wraparound belt has a first strap end, a second strap end, and a strap, net or supporting body extending between the first strap end and the second strap end to direct restraining forces from an occupant through the seat to the vehicle floor or structure. The strap, net, or supporting body extends at least partially through or is integrated with the seatback and may incorporate pretensioning, load-limiting and other features to increase and control occupant restraint in non-frontal crashes.

An occupant restraint device for a vehicle includes a three-point seatbelt device, a shoulder cover, an attachment portion, and a hard pad provided inside the shoulder cover. The three-point seatbelt device includes a shoulder belt that extends from an upper portion at a seat width direction one end side of a seat back toward a buckle at a lower portion at the seat width direction other end side. The shoulder cover is provided at the upper portion at the seat width direction one end side of the seat back. The shoulder belt is inserted through the shoulder cover, and the shoulder cover is arranged along a restrained surface of the vehicle occupant sitting on a vehicle seat. At the attachment portion, a side of the shoulder cover at which a terminal portion thereof is disposed is attached to the upper portion at the seat width direction one end side of the seat back so as to be relatively movable in an up-and-down direction with respect to the upper portion. The hard pad is disposed between the vehicle occupant sitting on the vehicle seat and the shoulder belt in a region opposing a collarbone of the vehicle occupant.

A motor vehicle and occupant seat combination may include any one or combination of means for selectively preventing forward pivoting of at least one vehicle seat, one or more web attenuators for dampen forces applied thereby by one or more respective shoulder webs of at least one occupant restraint system, at least one sleeve received on at least one shoulder web and a corresponding sleeve adjuster for adjusting a position of the sleeve along the respective shoulder web, and one or more ratcheting web retractors for selectively tightening a lap web or a thigh web about an occupant of at least one vehicle seat.
