A vehicle seat for a motor vehicle, with a seat frame that can be attached to a vehicle floor, with a seat part supported by the seat frame, and with a ventilating device that has at least one controllable air-conveying device and at least one air outlet device flow-connected to the air-conveying device. Provision is made that a seat part element that lengthens the seat part is mounted on the seat frame so as to be longitudinally movable relative to the seat part, and that the seat part element has the ventilating device.

The present disclosure refers to a tray table device for a vehicle seat that may have at least a table element and a table support structure connected to the table element. Further, the present disclosure refers to a vehicle seat that may have such a tray table device.

A vehicle seating assembly including a seat cushion and a seat frame assembly with a carrier assembly and a displaceable platform coupled to the carrier assembly and selectively deployable from a design position to a fully deployed position in response to a sudden deceleration of the vehicle.

An ECU device which estimates a length of a lower limb of a seated person who is seated in a vehicle seat is shown. The ECU device includes the following. A thigh angle information obtainer obtains information regarding a thigh angle of the seated person. A back knee angle information obtainer obtains information regarding a back knee angle of the seated person. An estimator estimates the length of the lower limb of the seated person based on the information regarding the thigh angle obtained by the thigh angle information obtainer and information regarding the back knee angle obtained by the back knee angle information obtainer.

A seat of a vehicle seating assembly includes a seat carrier, a thigh tilt housing, a thigh extension housing, and an inflatable member. The thigh tilt housing is coupled to a forward region of the seat carrier. A recess is defined by the thigh tilt housing, with the recess being positioned in an upper surface of the thigh tilt housing. A motor is received within the recess. The thigh extension housing is coupled to the motor, with the thigh extension housing being movable in a fore-aft direction relative to the thigh tilt housing. A fastener couples the thigh tilt housing to the seat carrier in a manner that permits pivotable motion of the thigh tilt housing along a vertical plane. The inflatable member is positioned between the seat carrier and the thigh tilt housing.

A seating posture is stabilized for the shoulders of a passenger seated on a vehicle seat. A vehicle seat is provided with a seat back configured to support the seated person from the rear. A shoulder support portion of the seat back configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand when air is supplied. When the air cell expands, one end portion of the shoulder support portion on the outside in the width direction of the vehicle seat moves more forward than the other end portion of the shoulder support portion on the inside in the width direction.

A passenger seat comprises a backrest and a seat element that includes a first portion adjoining the backrest and a second portion that can pivot between a rest position and an operational position. In the operational position, the second portion of the seat element increases a depth of a seat pan of the seat element that can be used by the user. A locking mechanism is configured to prevent a pivoting movement of the second portion of the seat element from the operational position thereof into the rest position thereof when a weight of a user sitting in the passenger seat acts on the seat element.

A seat cushion extension device is provided which can slide a seat cushion via a single spring, and has high assembly efficiency and a low weight due to a simple structure. The seat cushion extension device includes: a base having first and second rack gears provided to face each other; a cushion part provided on an upper portion of the base to move forward/backward; a locking gear part combined with a shaft extending from the cushion part to the base and having a first gear provided to be engaged with the first and second rack gears; and a manipulation part combined with the cushion part to move forward/backward between the cushion part and the first gear, and having a protruding part provided on a lower surface thereof.

A seat of a vehicle seating assembly includes a seat carrier, a thigh tilt housing, a thigh extension housing, and an inflatable member. The thigh tilt housing is coupled to a forward region of the seat carrier. A recess is defined by the thigh tilt housing, with the recess being positioned in an upper surface of the thigh tilt housing. A motor is received within the recess. The thigh extension housing is coupled to the motor, with the thigh extension housing being movable in a fore-aft direction relative to the thigh tilt housing. A fastener couples the thigh tilt housing to the seat carrier in a manner that permits pivotable motion of the thigh tilt housing along a vertical plane. The inflatable member is positioned between the seat carrier and the thigh tilt housing.

A vehicle seat for a motor vehicle includes a seat bottom and a seatback displaceable relative to one another. A seat positioning system has an actuator for displacing one of the seat bottom and the seatback toward the other of the seat bottom and the seatback. The system further includes a position sensor for generating a seat position signal indicative of a position of one of the seat bottom and the seatback relative to the other of the seat bottom and the seatback. The system further includes a controller for generating an activation signal in response to the controller determining that the position is above the position threshold. The actuator displaces one of the seat bottom and the seatback toward the other of the seat bottom and the seatback in response to the actuator receiving the activation signal from the controller.
