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.

An airbag apparatus is configured to be used for a vehicle seat including an accommodation portion. The airbag apparatus includes an airbag. The airbag is configured such that a portion of the airbag ejected from the accommodation portion to the position beside the headrest is deployed and inflated in a position rearward of the seat back, and is inflated and deployed away from the accommodation portion in the width direction in a position rearward of the headrest, and that another portion of the airbag ejected from the accommodation portion to the position beside the headrest is deployed and inflated in a position forward of the seat back, and is deployed and inflated in a position forward of a head of an occupant seated in the vehicle seat and away from the accommodation portion in the width direction, so as to wrap around the head.

The present invention relates to accessory systems for enhancing the security of restraint system used in a vehicle with a lap seatbelt system. A plurality of straps can placed on the upper surface of a vehicle seat and configured to provide a secure connection between the shoulders of the restraint system and an upper portion of the vehicle seat, the anchoring system securing the torso of the individual to the seat back. An optional plurality of straps are configured to provide a supplemental connection between the anchoring system and a rear portion of the seat, tethering the anchoring system to the vehicle to anchoring structures in the floor of the vehicle or the bottom portion of the seat. The straps can be adjusted to accommodate different heights in wearers, seats backs, and vehicle seats, making the restraint user adjustable for use by different wearers and in different vehicles.

An occupant protection device includes: a collision prediction unit configured to predict a collision state including a collision direction in a vehicle; a seat direction detection unit configured to detect a direction of a seat that is rotatable around a vertical axis of the vehicle with respect to the vehicle; a driving unit configured to adjust a degree of tension of a seatbelt; and a control unit configured to control the driving unit in accordance with the collision direction with respect to the vehicle predicted by the collision prediction unit and the direction of the seat with respect to the vehicle detected by the seat direction detection unit to change the degree of tension of the seatbelt.

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.

Disclosed is a retrofitting seatbelt system for a motor coach, the system including: a base plate, the base plate configured to connect to a floor rail of the motor coach; a longitudinal post configured to support a belt, the longitudinal post defines a longitudinal post inner end connected to the base plate, wherein the longitudinal post extends away from the base plate in a longitudinal direction to a longitudinal post outer end, wherein the longitudinal post defines a forward-side that faces a forward direction, and an aft-side that faces an aft direction, wherein the forward direction and the aft direction are disposed along a forward-aft axis; and a first motion damper connected to the longitudinal post near the longitudinal post outer end, the first motion damper extends in the aft direction, beyond the aft-side of the longitudinal post.

A vehicle seat that includes: a seat cushion that is configured to be raised and lowered in a seat vertical direction; a buckle that is attachable to an attachment location that is not subject to the raising or lowering of the seat cushion, and that retains a tongue provided at an elongated belt shaped webbing, in a state in which in the webbing is worn over at least a pelvis area of the occupant; and a lifting device that is actuated, in a case in which a collision of a vehicle has been detected, so as to move the occupant, in a case in which the occupant is sitting on the seat cushion, toward an upper side of the seat at a location further toward a rear side of the seat than a central portion of the seat cushion in a front-rear direction of the seat.

An advanced four-point seat belt may include: a three-point seat belt to diagonally hold a passenger with a webbing; and a motorized seat belt to allow a tongue of the webbing to maintain a state of being fixed to a side surface of a seat cushion to an initial position. In particular, when a vehicle collision situation is recognized, the motorized seat belt forms an “X” shape webbing confinement state by withdrawing the webbing and another webbing to locate the tongue at a central position of a body of the passenger.

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 restraint system for a vehicle seat operatively mounted in a motor vehicle may include a restraint web operatively coupled to at least one of the vehicle seat and the motor vehicle, an elongated sleeve received on and at least partially about the restraint web, and a sleeve position adjuster coupled to the sleeve and including an actuator normally engaging a portion of the restraint web to fix a position of the sleeve relative to the restraint web and responsive to actuation thereof to disengage from the restraint web to allow the sleeve to be moved along the restraint web.
