A seat frame is disclosed for a height-adjustable and tiltable seat pan of a motor vehicle seat. The seat frame has two side rails, a first cross bar, a second cross bar, and a drive unit. The first cross bar is supported in the two side rails and the second cross bar serves to support the seat pan. The second cross bar is mounted so as to be rotatable about fixed first axis in the two side rails. The second cross bar is rotated by the drive unit. The drive unit has an actuating motor and an actuator that is displaceable via the actuating motor and connected to the second cross bar outside the first axis. The drive unit is mounted on the first cross bar and rotatable about a second axis of the first cross bar which is fixed in the two side rails.

A passenger seat comprises a backrest, a seat element and a size increasing mechanism which is configured to convert a weight acting on the seat element when a user sits in the passenger seat into an increase in the depth of a seat pan of the seat element that can be used by the user from a rest-position depth to a to an operational-position depth.

A vehicle seat including a seat that includes a seat cushion and a seat back; an inclination drive portion configured to incline the seat back; and a slide mechanism configured to enable the seat to slide in a vehicle front-rear direction, in which the slide mechanism includes: a slide rail supporting to be able to move in a sliding manner in the front-rear direction; a slide drive portion configured to enable the upper rail to slide with respect to the lower rail; and a mode switching switch configured to enable mode switching, in the normal mode, a slide amount used by the seat when the vehicle is driven is used, in the relaxing mode, a slide amount at a position rearward with respect to the rearmost end in the normal mode is used, and, when the relaxing mode is switched to the normal mode, in a case where the seat back is inclined, the seat back is raised to the normal mode, and then the seat is moved forward to the normal mode.

A vehicle seating assembly includes a seat base with a support structure, a seatback pivotably coupled to the seat base, a first anchor access point positioned in the seat base, a second anchor access point positioned in the seat base and laterally disposed relative to the first anchor access point, a seat surface of the seat base. The seat surface includes a lower portion and a rearward portion. The rearward portion is positioned rearward of the lower portion. The rearward portion is arranged at an angle relative to the lower portion such that the rearward portion and the lower portion are non-parallel to one another. The seat surface is an occupant-facing surface.

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.

A vehicle seating system includes a seatback pivotally coupled to a seat base. The seatback is operable between an upright position and a reclined position. A lift assembly is operably coupled to the seat base. The lift assembly is operable between a disengaged position and an engaged position. A position sensor is coupled to the lift assembly via a ball joint, wherein the ball joint and the position sensor adjust with movement of the lift assembly. A seat controller communicatively is coupled to the position sensor, wherein the seat controller determines if the lift assembly is in the disengaged position or has moved to the engaged position based on position data received from the position sensor.

A vehicle seat having a seat bottom comprising a ramp and a stop, a slide comprising a first slide segment and a second slide segment, a movable element capable of being moved relative to the slide, the seat bottom being pivotally mounted relative to the movable element about a pivot axis, an articulation member that is stationary relative to the slide member, and a pivoting connecting rod having a first end that is articulated to the articulation member and a second end able to slide against the ramp during the movement of the movable element on the first slide segment, the pivoting connecting rod being shaped to push against the ramp and cause the rotation of the seat bottom during the movement of the movable element on the second slide segment, the second end of the connecting rod bearing against the stop.

A passenger seat for an aircraft, including a bottom support configured to be connected to a floor of the aircraft, a seat pan frame, and a support structure interconnecting the seat pan frame to the bottom support, the support structure including a front support member pivotally connected to a front end of the seat pan frame, the front support member including a respective strut on each side of the seat pan frame, each respective strut having a bottom end rigidly connected to the bottom support and an opposed top end located under the seat pan frame, the bottom end being inwardly, downwardly and rearwardly offset with respect to the top end.

A seat pan adjustment system for an ejection seat may comprise a guide bracket defining a channel and a seat pan mount configured to translate relative to the guide bracket. A support bracket may extend from a surface of the seat pan mount. A rod may be located through a rod opening defined by the support bracket. The rod may be located in the channel. A biasing member may be coupled to the rod and configured to force the rod away from the surface of the seat pan mount.
