A vehicle seat structure including: a mode switching mechanism including: a rotating mechanism which is configured to switch one seat of two seats between a state where the one seat faces a vehicle front direction and a state where the one seat faces a vehicle rear direction by rotating the one seat; and a slide mechanism which is configured to move another seat of the two seats from a laterally located position where the other seat is located side by side with the one seat to a vertically located position where the other seat is located to face, in the front-rear direction, the one seat facing the vehicle rear direction by obliquely sliding the other seat in a rear direction and in the seat width direction from the laterally located position.

An underbody structure for supporting an adjustable seating assembly for a motor vehicle comprises a rotatable turntable operably coupled to an underbody of the motor vehicle and a brace operably coupled with the rotatable turntable and the underbody of the motor vehicle and extending substantially across the rotatable turntable, wherein the adjustable seating assembly is operably coupled to the brace and the underbody of the motor vehicle.

A vehicle seat structure including a first seat and a second seat, wherein the first seat includes: a tilting rotation mechanism configured to connect the first seat with respect to a floor in a manner switchable between a sitting position and a raised position; and a pivoting mechanism configured to pivotably connect the first seat to the floor with the tilting rotation mechanism provided therebetween, and wherein the second seat includes a concave portion configured to reduce interference between the second seat and a forefoot of a sitting occupant of the first seat which is being pivoted in the raised position when the second seat and the first seat are in a positional relationship in which the second seat overlaps, in a plan view, with a pivoting trajectory of the forefoot of the sitting occupant of the first seat which is being pivoted in the raised position.

The rotation device includes means for locking the seat in extreme angular positions, comprising a movable abutment carried by the seat, and interacting with a complimentary fixed abutment when the seat is in one of its extreme angular positions. The movable abutment may be moved between a locked position in which it abuts the fixed abutment, and an unlocked position in which it is above the fixed abutment. The device has a means for unlocking the seat, wherein it comprises at least one pneumatic control member and pneumatic means for driving the movable abutment from its locked position to its unlocked position when the control member is actuated.

A seating assembly includes a turntable that is rotatable about a first vertical axis. A seatbase is slidably coupled to the turntable. The seatbase is configured to slidably actuate regardless of a rotational position of the turntable. The seating assembly may be installed in a vehicle.

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.

The rotation device (10) comprises means for locking the seat in extreme angular positions, comprising a movable abutment (23) carried by the seat (8), and interacting with a complementary fixed abutment (25) when the seat is in one of its extreme angular positions. The movable abutment (23) may be moved between a locked position in which it abuts the fixed abutment (25), and an unlocked position in which it is above the fixed abutment (25). The device (10) comprises means for unlocking the seat, wherein it comprises at least one pneumatic control member and pneumatic means (30) for driving the movable abutment (23) from its locked position to its unlocked position when the control member is actuated.
