A head restraint assembly includes a front shell and a rear shell defining an interior space. The head restraint assembly also includes a linkage mechanism operatively coupled to the front shell, the linkage mechanism disposed within the interior space, the linkage mechanism spring biased toward a first position. The head restraint assembly further includes an actuator in operative communication with a collision detection system, the linkage mechanism movable to a second, deployed position upon actuation by the actuator to lock the front shell in the second, deployed position.

A deployable headrest airbag includes an airbag chamber configured to be coupled to a headrest of a vehicle seat. The airbag chamber has a stowed position and a deployed position. In stowed position, the airbag chamber is disposed inside the headrest. In the deployed position, the deployable headrest airbag is disposed outside of the headrest to protect a head and a neck of a vehicle occupant.

Described are passenger seat assemblies having an impact bracket for a support pin. The support pin may be a component of a monitor assembly. The impact bracket includes a body that defines an aperture and a flex member within the aperture. The flex member defines a support region and a travelling region of the aperture. The flex member retains the support pin in the support region responsive to a load that is less than a minimum impact load, and releases the support pin from the support region into the travelling region responsive to a load that is at least the minimum impact load.

A vehicle occupant protection device includes a vehicle seat, a steering wheel, a steering moving mechanism, and a control unit. The vehicle seat includes a seat back and a headrest, the vehicle seat being con gored to turn between a position where the vehicle seat is directed toward a vehicle front side and a position where the vehicle seat is directed toward a vehicle rear side. The steering wheel is provided ahead of the vehicle seat in a vehicle front-rear direction. The steering moving mechanism is configured to change a position of the steering wheel. The control unit is configured to move the steering wheel to a support position where the seat back and the headrest are supported by the steering wheel from the vehicle front side, by the steering moving mechanism, when the vehicle seat is directed toward the vehicle rear side.

A head restraint assembly is arranged to removably couple a head restraint to a vehicle seat. The head restraint assembly includes an engagement component having a retention feature configured to engage a complimentary engagement component of the vehicle seat during a deceleration event to maintain attachment of the head restraint to the vehicle seat.
