In a physical state sharable seat, a sensor is configured to acquire a measurement value specific to a physical state of an occupant seated on the seat body; and a controller connected to the sensor and thereby allowed to acquire the measurement value from the sensor is configured to be capable of communicating with other equipment. The controller includes: an evaluation unit configured to compute an evaluation value on the physical state, based on the measurement value; an evaluation value presentation unit configured to present the evaluation value at a terminal to be used by the occupant; a shared data acquisition unit configured to acquire an other-occupant evaluation value that is an evaluation value on a physical state of another person, acquired either by the evaluation unit or from another physical state sharable seat; and a shared data presentation unit configured to present the other-occupant evaluation value at the terminal.

A motion sickness control system for a vehicle includes a vibrator. The motion sickness control system includes a sensor configured to measure vibration of the vehicle. The motion sickness control system includes a computer having a processor and a memory storing instructions executable by the processor to actuate the vibrator at a target frequency based on the measured vibration of the vehicle. The target frequency attenuates the measured vibration of the vehicle.

A method is described for adapting a position of a seat device of a passenger of a vehicle during and/or prior to a switchover of the vehicle from an automated driving mode to a manual driving mode, the method having at least a step of providing, in which an adjustment signal is provided to an interface to a seat device of the vehicle using a transition signal and a position signal, and the adjustment signal causes a change in the position of the seat device from a comfort position to an upright position, and the transition signal indicates or represents an upcoming transition from an automated driving mode to a manual driving mode of the vehicle, and the position signal indicates or represents the position of the seat device of the passenger, the provision of the adjustment signal taking place when the position signal indicates or represents the comfort position, and/or the provision not taking place when the position signal indicates or represents the upright position; and/or providing a blocking signal in response to the transition signal when the position signal indicates or represents an upright position, the blocking signal blocking an adjustment of the upright position to a comfort position by the passenger.

The present disclosure relates to a pneumatic adjusting device for adjusting a side wing of a vehicle seat from a default position to an actuation position, the adjusting device comprising: a two-armed lever having an outer lever arm for adjusting the side wing and an inner lever arm, an inflatable balloon device, e.g. balloon, for adjusting the inner for adjusting the arm, and mechanical spring means for adjusting the inner for adjusting the arm. Hereby, it is provided that, in the default position of the adjusting device, the balloon device is inflated, in the default position, the spring means is tensioned and biases the inner lever arm into the actuation position, and in the actuation position, the spring means compresses the balloon.

Disclosed is a gearing device for a seat including a first internally toothed gear, a second internally toothed gear, an externally toothed gear, and an eccentric member. The first internally toothed gear includes a rotation center axis. The second internally toothed gear has the rotation center axis in common with the first internally toothed gear and is rotatably supported by the first internally toothed gear. The externally toothed gear is arranged to an inner side of the first and the second internally toothed gear, to thereby mesh with the first and the second internally toothed gears. The eccentric member rotates the externally toothed gear such that a rotation center thereof follows a path around the rotation center axis, rotatably supports the externally toothed gear about the rotation center, and rotates about the rotation center axis in response to a rotational force being externally input thereto.

The invention concerns a system for controlling a smart vehicle seat (1) having a seat base (1b) and a backrest (1c), the surfaces of which are provided with flat pressure sensors, the pressure sensors being connected to a microcontroller (6) via which an actuator element is controllable via a drive unit (9), whereby the actuator element is adapted to change the surface of the seat base (1b) and/or the backrest (1c). It is the object of the invention to develop the system in a way that it automatically adapts to a sitting posture of a user and adjusts the surface of the seat base and of the backrest in an extremely flexible and exactly way depending on the user's posture. Therefore, the invention proposes, that the actuator element comprises one or more valves via which one or more airbags are controllable. Furthermore the invention proposes to use graphene sensors as pressure sensors and to integrate an artificial intelligence module (7) on the microcontroller (6).

A motor vehicle seat with a lying function has a seat cushion, a backrest which is arranged on a first end region of the seat cushion, and a calf support which can be elongated and which is arranged on a second end region of the seat cushion. The calf support is provided with a lifting device for lifting two outer support panels out of a rest position and into a support position which protrudes beyond a support surface of the calf support.

A child safety seat for fitting on a vehicle seat of a vehicle, having: a seat element, a backrest element, in particular with an upper backrest part and a lower backrest part, wherein the backrest element is pivotable between a use position and a transport position, two side elements which are connected to the longitudinal edges of the backrest element, wherein the side elements each have a viscoelastic foam plate and a substantially air-tight outer casing around the viscoelastic foam plate, wherein the viscoelastic foam plates are held on the backrest element with fastening elements, wherein the fastening elements penetrate the viscoelastic foam plates and the outer casings in such a manner that air suction openings for sucking up air into the viscoelastic foam plates are formed.

A seat and accessory connection system for a vehicle includes: a connection base configured to be connected to the vehicle; a seat configured to be removably connected to the vehicle at a first location on the connection base, the seat comprising at least one first connecting feature; and an accessory configured to be removably and selectively connected to either one of the connection base at the first location and the vehicle at a second location on the vehicle. The accessory has at least one second connecting feature for removably connecting the accessory to the first location and the second location. The connection base has at least one third connecting feature configured to selectively engage the at least one first connecting feature of the seat and the at least one second connecting feature of the accessory to removably connect the seat or the accessory at the first location.

A vehicle seat comprises at least one vibration device comprising an electroacoustic transducer, the vibration device having a mass less than or equal to 130 g.
