Emergency vehicle patient transport systems are disclosed. In one embodiment, an emergency vehicle patient transport system includes: a loading passage providing access to an interior of an emergency vehicle; one or more tracks coupled to a floor of the emergency vehicle, a ceiling of the emergency vehicle, a wall of the emergency vehicle or combinations thereof wherein, a travel path is delineated by the one or more tracks; and a chair slidingly engaged with the one or more tracks, and vertically positioned between the floor and the ceiling. The chair locks in one or more set positions. And, the one or more set positions are selected from a group consisting of an airway care position, an extended airway care position, a procedural care position, a responder position, a patient care position, and a patient load position.

A device for reducing kinetosis-related disorders of an occupant of a vehicle includes a vehicle seat with a headrest. A seat belt is assigned to the vehicle seat which is configured to increase a connection of the occupant to the vehicle seat before an onset of an acceleration. An actuator system is coupled to the headrest which is configured to move the headrest automatically, at least in sections, counter to an expected direction of an acceleration of a head of the occupant before the onset of the acceleration. The seat belt is tightenable by a reversible belt tensioner before the onset of the acceleration.

The invention relates to a vehicle seat comprising a vehicle seat upper part and a vehicle seat lower part, which are spaced apart from one another along a height axis and are connected to one another by means of a scissor frame arrangement, wherein the scissor frame arrangement comprises at least one inner swinging arm and at least one outer swinging arm, wherein the at least one inner swinging arm and the at least one outer swinging arm are mechanically coupled, whereby an angle of inclination of the vehicle seat upper part relative to the vehicle seat lower part can be specified, wherein the mechanical coupling comprises an arm element and a first connecting element pivotably connected thereto, wherein the angle of inclination can be specified by a length of the first connecting element.

A seat assembly is provided with a seat bottom, a seat back, and a plurality of sensors operably connected to at least one of the seat bottom and the seat back to detect a seating condition of a seated occupant. A controller is in electrical communication with the plurality of sensors. The controller is programmed to receive input from the plurality of sensors indicative of a seating condition of the seated occupant. The seating condition is compared to a predetermined seating condition. An output indicative of the predetermined seating condition is transmitted. An actuator is in electrical communication with the plurality of sensors and operably connected to at least one of the seat bottom and the seat back for adjustment of at least one of a plurality of settings of the seat assembly. The actuator is adjusted to a predetermined setting corresponding to the predetermined seating condition.
