A vehicle seat arrangement includes a vehicle seat arranged to be adjusted between a forward facing setup and a rearward facing setup and a seat back rotation axle. A seat back is rotatable around a seat back rotation axle between a forward facing seat back setup and a rearward facing seat back setup. The seat cushion is arranged to be adjusted between a forward facing seat cushion setup and a rearward facing seat cushion setup. The seat back rotation axle may be arranged to be fixed in location and the seat cushion may be arranged to be displaceable horizontally or the seat back rotation axle may be arranged to be displaceable horizontally and the seat cushion may be arranged to be fixed in location.

The present disclosure provides a seat control system for a vehicle, which may sense whether passengers have been seated on a front seat and a rear seat, and easily implement sleep and rest postures of the front seat and the rear seat through the height adjustment, the reclining adjustment, and the like of the front seat and the rear seat according to the sensed result.

A zero-gravity seat comprises a seat base, a seat back, a front support frame, and a rear support frame. Upper ends of the front support frame and the rear support frame are respectively hinge-connected to front and rear ends of the seat base. Lower ends of the front support frame and the rear support frame are respectively hinge-connected to a seat mounting base. A lower end of the seat back can rotate around a rear end portion of the seat base. When the seat back and the seat base rotate in a linked manner, a small step difference or even no step difference is present between a lower end portion of the seat back and the upper end surface of the seat base such that the back of the occupant conforms to the seat back, thereby ensuring the comfort of a ride.

A reclinable passenger seat includes a seat pan linear actuator having a rear end pivotally connected to the rear end of the seat pan frame, and a front end pivotally connected to the base by a third fixed pivot. A backrest linear actuator has an upper end pivotally connected to the upper backrest member, and a lower end pivotally connected to the base. A length of the backrest linear actuator is defined between the upper and lower ends. The backrest frame and seat pan frame are configured to move simultaneously between at least a reclined configuration and a berth configuration through pivoting motion about the first and second fixed pivots and about the first and second locations. The length of the backrest linear actuator is substantially the same in the reclined configuration and in the berth configuration.

The disclosure discloses an automobile seat based on an inclined angle adjustment mechanism, including a seat body composed of a cushion skeleton, a backrest skeleton, and a base arranged under the seat body. The upper surface of the base is of a non-plane structure and includes a pedestal located at the lower part and a branch located at the upper part which is integrated or connected by a fixed member, the back of the pedestal is movably connected with the lower part of a third connection rod, the upper part of a seventh connection rod is movably connected with the front of a forth connection rod, and the middle of the seventh connection rod is movably connected with the upper end of the branch, and rotation points are located near the H point of the seat.

A reclinable passenger seat including a base, a seat pan frame having a front end connected to the base via a first fixed pivot, a support arm having one end connected to the base via a second fixed pivot aft of the first fixed pivot, and a backrest frame having an upper backrest member and a lower backrest member. An opposed end of the support arm is pivotally connected to the lower backrest member at a first location spaced from the upper backrest member. A rear end of the seat pan frame is pivotally connected to the lower backrest member at a second location between the first location and the upper backrest member. The backrest frame and seat pan frame are configured to move simultaneously between a sitting configuration and a reclined configuration through pivoting motion about the fixed pivots and about the two locations.

A reclinable passenger seat including a base, a seat pan frame having a front end connected to the base via a first fixed pivot, a support arm having one end connected to the base via a second fixed pivot aft of the first fixed pivot, and a backrest frame having an upper backrest member and a lower backrest member. An opposed end of the support arm is pivotally connected to the lower backrest member at a first location spaced from the upper backrest member. A rear end of the seat pan frame is pivotally connected to the lower backrest member at a second location between the first location and the upper backrest member. The backrest frame and seat pan frame are configured to move simultaneously between a sitting configuration and a reclined configuration through pivoting motion about the fixed pivots and about the two locations.

A motor vehicle seat with a seat inclination adjustment device, with a first base element, a first seat frame element and a first actuator element, the actuator element has a lower link arm connected to the base element and arranged movably relative to the base element, an upper link arm connected to the lower link arm and movably arranged relative to the lower link arm, the upper link arm is connected to the seat frame element and is movably arranged, and a linear actuator with first and second linear actuator elements, the first linear actuator element is movably connected to the second linear actuator element and the first linear actuator element is movably connected to the base element and the second linear actuator element is movably connected to one of the link arms.

A headrest adjusting device for headrest adjustment with respect to a backrest may have a headrest mounting bracket and a slide device movable mounted on the headrest mounting bracket. The headrest mounting bracket may have a seat belt retainer movable mounted on the headrest mounting bracket. A seat structure for a vehicle seat may also have the headrest adjusting device.

A passenger seat includes a bottom support to be connected to the aircraft floor, a seat pan frame, and a support structure interconnecting the seat pan frame to the bottom support. A front support member defines a frontmost portion of the support structure, and has a top end connected to a front end of the seat pan frame and a bottom end connected to the bottom support. The front end of the seat pan frame is forwardly offset from a front end of the bottom support and the top end of the front support member is forwardly offset from its bottom end such that an empty space is defined across a width of the seat between the seat pan frame and the floor, forwardly of the support structure, forwardly of the bottom support, and rearwardly of a vertical plane aligned with the front end of the seat pan frame.
