An ISS is a seating system that actively adjusts to improve an occupant's comfort, performance, and safety in a specific driving environment. The ISS determines the occupant's posture, position on the seat surface, and/or physiological state, for example, by applying a machine vision process. The ISS can further determine a driving environment. The ISS adjusts its settings and settings of the vehicle according to one or more factors such as an occupant's posture, the occupant's physiological state, the occupant's preferences, and/or the driving environment. The ISS can include a state machine that determines a current state and determines if a change has occurred such that the system should shift to another state that best suits this change. The ISS makes adjustment according to system settings associated with the best suitable state.

A structural component may have a carrier structure and a substructure arranged on the carrier structure and having a variable contour. The substructure may have an adjustment mechanism with a plurality of adjustment elements. The adjustment mechanism may be configured to adjust the adjustment elements between a compressed position and an expanded position in order to vary the contour.

A seatback and/or a seat cushion has left and right side frames arranged spaced apart in a left-right direction, and wire laid between the left and right side frames. The wire extends substantially in parallel to the side frames. A pad is placed on the side frames and the wire. The pad includes a first pad layer on the side of a seating surface, and a second pad layer on a side of the pad opposite to the seating surface. The second pad layer is harder than the first pad layer. The second lad layer is supported while being in contact with the side frames and the wire.

At a vehicle seat, resistance to relative displacement of a passenger in a left-right direction is larger at both left-right direction side portions of a front surface of an upper portion of a backrest than at a left-right direction central portion. Further, a seat cushion has left and right side reinforcing portions that reinforce portions of a cushion pad from outer sides in a left-right direction, and from obliquely lower sides, of front-rear direction central portions of thigh portions of the passenger, and left and right lower surface reinforcing portions that reinforce portions of a lower surface of the cushion pad at outer sides in a left-right direction, and at obliquely lower sides, of buttock portions of the passenger.

The invention relates to a seat arrangement for a means of transport, in particular for a means of passenger transport, wherein the seat arrangement can be arranged on the means of transport by means of a fastening device, wherein the seat arrangement comprises at least one frame element with an upper region which is provided and suitable for supporting the back and at least one seat region which is integrated into the at least one frame element.

A seat assembly includes a first seatback and a second seatback. The first seatback may include a first seatback upper portion and a first seatback lower portion. The second seatback may include a second seatback upper portion and a second seatback lower portion. The seat assembly may further include an intermediate back section including an intermediate upper portion and an intermediate lower portion. The first seatback lower portion and the second seatback lower portion may be arranged on opposite sides of the intermediate lower portion. The seat assembly may also include a carrier frame to which the first seatback upper portion, the second seatback upper portion, and the intermediate upper portion may be connected. At least one of the first seatback upper portion, the second seatback lower portion, and the intermediate upper portion may be adjustably connected to the carrier frame.

To provide a technique that enables the reduction of fatigue of a vehicle occupant at low cost and without an increase in the number of parts. Without preparing a sensor in addition to a posture changing mechanism, the position of a lumbar vertebra or thoracic vertebra of each vehicle occupant is estimated by controlling the operation of the posture changing mechanism. The posture changing mechanism includes: a back side support mechanism; a first motor capable of shifting a position of the back side support mechanism with respect to a vertical direction; and a second motor capable of shifting the position of the back side support member with respect to a front-back direction. A position of a lumbar vertebra of the vehicle occupant is estimated by: while changing the vertical position of the back side support mechanism by means of the first motor, changing a forward position of the back side support mechanism at each of the different vertical positions thereof by means of the second motor so as to obtain a turnover number value of the second motor achieving a desired resistance; and comparing the turnover number values of the second motor achieving the desired resistance. A position of the thoracic vertebra is determined by calculation based on the position of the lumbar vertebra. The position of the posture changing mechanism is set based on the results of estimation of the individual positions. Thus, a fatigue reduction effect is provided on the vehicle occupant by utilizing the posture changing mechanism.

The invention relates to a seat arrangement for a means of transport, in particular for a means of passenger transport, wherein the seat arrangement can be arranged on the means of transport by means of a fastening device, wherein the seat arrangement is intended and suitable for providing a sitting position at standing height, wherein the seat arrangement comprises at least one frame element, wherein a seat cover is arranged on or in the at least one frame element, wherein the seat cover is a knitted fabric.

A seat back (20) includes an upper thoracic support section (20a) for supporting at least a portion corresponding to a lower part of the upper thoracic spine of a seated occupant, and a lower thoracic support section (20b) disposed on a front side with respect to the upper thoracic support section (20a) and configured to support a portion corresponding to the lower thoracic spine of the seated occupant. The lower thoracic support section (20b) is configured to displace backward greatly, as compared with the upper thoracic support section (20a) in such, a way that the upper thoracic spine of the seated occupant is inclined forward, when backward inertia force acts on the seated occupant.

A seat arrangement for passenger transport, wherein the seat arrangement can be arranged on the vehicle by a fastening device. The seat arrangement is intended and suitable for providing a sitting position at standing height, wherein the seat arrangement comprises at least one frame element. The frame element is arranged on the fastening device by at least one mounting shaft, wherein the at least one frame element can be pivoted relative to the fastening device about a pivot axis extending along a width axis.
