A seat device, particularly aircraft seat device, includes at least one head-support module, which device has a central cushion unit and at least one lateral cushion unit, wherein the lateral cushion unit is supported movably relative to the central cushion unit.

A vehicle occupant protection device, that includes: a vehicle occupant protection control unit that, in a case in which a rear impact of the vehicle is predicted, effects control such that a seat of the vehicle approaches a rear impact protection attitude that protects a vehicle occupant from a rear impact, and that, in a case in which the vehicle is forcibly stopped, effects control such that a driver seat of the vehicle approaches closer to the rear impact protection attitude than in the case in which a rear impact of the vehicle is predicted.

A vehicle seat structure that includes: a seatback that is provided at a seat rear side of a seat cushion so as to be able to tilt in a seat front-rear direction with respect to the seat cushion, and that can support an upper body of a vehicle occupant; a headrest that is provided at a side of the seatback, which side is opposite from a side at which the seat cushion is located, and that can support a head portion of the vehicle occupant; and shoulder restraining portions that are provided at the headrest or at the headrest side of the seatback, and that, by protruding out toward a vehicle occupant side at a time of an emergency of a vehicle, restrain both shoulders of the vehicle occupant in a case in which the vehicle occupant has moved along the seatback toward the headrest side.

A multi-direction power actuated head restraint assembly includes a head restraint mountable to a vehicle seat. The head restraint assembly also includes a fore-aft power actuation mechanism including a fore-aft electric motor to adjust a fore-aft position of the head restraint, the fore-aft electric motor programmed to adjust the fore-aft position at a first fore-aft speed during manual adjustment of the head restraint and at a second fore-aft speed upon detection of an imminent impact by an impact detection system, the second fore-aft speed greater than the first fore-aft speed.

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 child conveyance device includes an impact energy absorbing apparatus disposed on a portion of the child conveyance device. The impact energy absorbing apparatus includes an inner support configured to be positioned against the portion of the child conveyance device. The inner support has a receptacle formed therein. The impact energy absorbing apparatus further includes an outer cover configured to releasably secure the inner support and an insert received within the receptacle of the inner support. The insert is held in place by the outer cover when securing the outer cover.

A vehicle-mounted seat device includes an SB main frame, a backrest, a relay disk secured at the center in the width direction of the backrest, a plurality of radial wires for suspending the backrest such that the backrest can swing relative to the SB main frame with the relay disk as the center, an SB subframe capable of swinging together with the backrest, a headrest, a headrest stay extending downward from the headrest and mounted on the SB main frame so as to rotate around a rotation shaft; a pressure-receiving body secured on the headrest stay so as to be disposed behind and opposed to the relay disk; and a provisional connection mechanism for provisionally connecting the headrest stay to the SB main frame.
