A seat assembly for use in a vehicle is repositionable between a design seating position, a folded position, and a slouch position. The seat assembly comprises a seatback fixedly coupled to a first recliner bracket, a seat cushion having a cushion bracket, a recliner pivotally connecting a second recliner bracket to the first recliner bracket, and a hockey stick assembly pivotally connected to the seatback and the first recliner bracket through the recliner and the second recliner bracket. The cushion bracket is pivotally connected to the hockey stick assembly and the second recliner bracket through a free pivot joint. The seat cushion is coupled to a track that is slidably coupled to a fixed track. The hockey stick assembly repositions the seatback between the design seating position and the slouch position as the track slides along the fixed track.

An apparatus of tilting a seat cushion of a rear seat may include a tilting function additionally provided to a seat cushion of a rear seat, so when a seatback reclines, it is possible to tilt up the front end portion of the seat cushion and sufficiently support the thighs of a passenger sitting in the rear seat using the front end portion of the seat cushion tilted upwards.

The utility model relates to the technical field of a cushion structure of an electric vehicle, and discloses a variable-form cushion structure of electric vehicle. The variable-form cushion structure specifically comprises a chassis with sliding rails, and a cushion unit, wherein, the chassis is arranged longitudinally, and the sliding rails extend longitudinally; the cushion unit comprises a support plate and a seat plate, and the lower end of the seat, plate is hinged to the upper end of the support plate; the lower end of the support plate is fixedly arranged, and the upper end of the seat plate is connected in a movable way with the sliding rails; when the upper end of the seat plate is located at the upper parts of the sliding rails, the seat plate is obliquely arranged relatively to the ground; and when the upper end of the seat plate moves to the lower parts of the sliding rails, the seat, plate is arranged, horizontally. The cushion structure of the electric vehicle can be switched among different modes according to the driver's requirements, so as to meet different requirements and improve the driver's driving experience and safety.

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.

The seat cushion is coupled to a track that is slidably coupled to a fixed track. The hockey stick assembly repositions the seatback between the design seating position and the slouch position as the track slides along the fixed track.

An adjusting system is provided for a seat, in particular a motor vehicle seat. A longitudinal axis, in which a person sitting on the seat is facing, is defined for the seat, and a transverse axis running perpendicularly to the longitudinal axis and a height axis running perpendicularly to the transverse axis and the longitudinal axis are also defined. The adjusting system comprises at least one first bearing ring which can be connected to the seat, at least one second bearing ring which can be connected to a seat mounting, and a plurality of adjusting rings which are connected to one another in a sequential manner and which are arranged between the first bearing ring and the second bearing ring. The adjusting rings can be rotated relative to one another in order to pivot the seat selectively about the longitudinal axis, the transverse axis, and the height axis.

A vehicle seat includes a cushion frame, a base portion, and a guide structure. The guide structure includes a rail and a rolling mechanism. The rolling mechanism includes an upper guide roller, a lower guide roller, and a roller holder. The rolling mechanism is sandwiched by an upper rolling surface and a lower rolling surface of the rail. The guide structure is configured such that when an occupant load is input to the cushion frame, the guide roller and the rolling surface at one of a first contact point or a second contact point come relatively close together, such that pressure increases, due to a relative position of the roller holder and the rail changing, with the other of the first contact point or the second contact point as a reference point.

A vehicle seat including: a connection mechanism; a seat cushion connected to an interior structure of a vehicle via the connection mechanism and configured to be displaced between a first state and a second state at which the seat cushion is arranged at a position closer to a front part-side of the vehicle than at the first state; and a seat back, wherein a sitting surface of the seat cushion at the first state gradually inclines upwardly from the rear of the seat towards the front of the seat, and wherein the connection mechanism is configured to displace the seat cushion to the second state and move a front part-side of the seat cushion more downwardly than at the first state, whereby the sitting surface of the seat cushion is made more horizontal at the second state than at the first state.
