Disclosed is a seat for a vehicle configured to variously adjust a seat position between, for example, a full-flat mode, a relaxation mode, a cushion tip-up mode, a full-bed mode, a walk-in mode, and a rear-view mode using a first hinge shaft to rotate the entire seat, including a seatback and a seat cushion, and a second hinge shaft to rotate the seatback.

The present invention has an object to provide a seat for vehicles in which a seat cushion escape mechanism can be space-saving. A seat for vehicles which has an escape mechanism (300) to shift a seat cushion frame (200) disposed on a base part (5) from a seating posture (200-1) to an escape posture (200-3) with the frame (200) placed forward of the base part (5) includes: a support leg part (301) having one end rotatably connected to the frame (200) and the other end rotatably connected to the base part (5); a guide part (201a) to be engaged with the one end of the support leg part (301) to guide the one end so as to lift the one end; a coil spring (305) biasing the support leg part (301) so as to have the one end guided by the guide part (201a) and flip up a portion (303) connected with the frame (200); and a second coil spring which is provided at the other end and applies a biasing force so as to rotate the one end of the support leg part (301) forward with the other end as a center.

The embodiment described and claimed herein are improved barrier-type wheelchair securement systems. In particular, one embodiment of a barrier includes an integral shoulder belt assembly, two integral wheelchair restraint assemblies, and two integral lap belt assemblies. The wheelchair restraint and lap belt assemblies comprise retractors which can be mounted external or internal to the barrier. The integral shoulder belt assembly could be connected to a vertical telescoping member which is movable from a first position, wherein the telescoping member is housed inside of the barrier, to a second position, wherein the shoulder belt assembly is disposed at a proper height for a wheelchair passenger. Alternatively, the shoulder belt assembly could be rigidly mounted to the barrier in a fixed position, or could be adjustable to accommodate passengers of varying size.

A vehicle seat includes a fixed frame installed in a vehicle body, a rotating link connected to the fixed frame through a rotation shaft and rotating relative to the rotation shaft, a seat cushion frame having one side of a rear end portion hinge-connected to the rotating link at a first connection point to rotate the rotating link when rotating, and a seat back frame having one side of a lower end portion hinge-connected to the fixed frame at a second connection point and the other side of the lower end portion hinge-connected to the other side of the rear end portion of the seat cushion frame at a third connection point to rotate relative to the fixed frame when the seat cushion frame is rotated.

A rear seat assembly for a vehicle is disclosed in which the seat cushions and the seat backs may be positioned on top of one another from a flat usage position into a non-usage position. Folding the seat cushions on top of one another and, folding the seat backs on top of one another takes place in order to form the loading space in the region of the back seat arrangement. The seat cushions and the seat backs, respectively, are stowed in a compact manner in the region of the passenger car and provides sufficient space for forming the loading space in the region of the back seat arrangement.

A power swivel device for a vehicle seat is configured to perform both swivel and monopost functions of the vehicle seat. The power swivel device includes a motor configured to swivel the seat and a reduction gear device configured to increase output torque of the motor, which are stacked in a vertical direction on a bottom of the seat. The power swivel device includes a lower housing; an upper housing stacked on and assembled to the lower housing; an eccentric shaft rotatably disposed relative to the lower housing and the upper housing; a motor driving unit mounted between the lower housing and the eccentric shaft; the reduction gear device installed between the upper housing and the eccentric shaft; and a swivel plate rotatably mounted on the reduction gear device and connected to a seat cushion frame.
