An apparatus for changing positions of a seat for vehicles includes mechanisms for adjusting the height of the seat for vehicles, adjusting reclining of the seat for vehicles, changing the seat for vehicles into a knee rest posture and changing the seat for vehicles into a relaxed comfort are integrated into one structure. Accordingly, a user selectively implements adjustment of the height of the seat for vehicles, adjustment of reclining of the seat for vehicles, change into the knee rest posture, and change into the relaxed comfort posture, etc., through operation of the switch.

An airplane seat device includes at least one functional unit that is configured at least for a locking, a controlling and/or a movement of at least one airplane seat element, wherein the functional unit includes at least one actuatable shape-memory element.

A head restraint of a vehicle seat includes a base element, at least one connection element positioned on the base element for connecting the base element to a backrest of a vehicle seat, a bearing element having a contact surface for contacting a head of a user of the vehicle seat, and a holding element which can be adjusted along a depth axis relative to the base element. The depth axis is oriented perpendicular to the contact surface. The bearing element is connected to the holding element by a damping device, wherein the damping device damps a movement of the bearing element relative to the holding element.

A rest device for a vehicle, including a support and an element that adjustable relative to the support. In addition, a drive unit including a drive motor is provided, which can be activated for the motor-driven adjusting of the element relative to the support, the drive unit being designed such that the element can be adjusted relative to the support both manually and using a motor.

An electropneumatic switch arrangement having an actuation device plurality of pneumatic outlets for connection to fluid-fillable devices, and a pneumatic supply connection for connection to a pressure source, the actuation device being connected to a sealing device, the actuation device being designed in such a way that, when it is actuated, it opens a predefined flow path between the supply connection and at least one of the outlets and, in doing so, closes a current path for actuating the pressure source, characterized in that the sealing device is mechanically coupled to the actuation device in such a way that at least a part of the sealing device is moved, in particular displaced, by the actuation device when this is actuated, thereby opening a flow path between the supply connection and at least one of the outlets.

A rail for a vehicle seat having first and second sliding rail members driven by a motorized drive mechanism. The rail further comprises a mechanical lock actuated by a relative movement between the motorized drive mechanism and the second rail member in the event of an accident.

A vehicle seat management system configured to adjust one or more seats based on occupant and/or vehicular data. In one aspect, the occupant and/or vehicular data may be sent to a remote device for calculation of a seat adjustment algorithm. In another aspect, the seat adjustment algorithm may be sent via wireless transmission. In one example, the wireless transmission may be 5G.

A vehicle proposed herein includes a swivel, a lock mechanism selectively locking and unlocking the swivel, a seat mounted on the swivel, a plurality of surface pressure sensors each disposed along an outer surface of the seat and detecting a pressure distribution within a predetermined area of the outer surface, and a controller configured to cause the lock mechanism to be unlocked based on a change in pressure distribution or a surface pressure that is detected by any of the plurality of surface pressure sensors.

A seat assembly may include a seat, a biomedical sensor, a bladder assembly, a pulsed electromagnetic field (PEMF) coil assembly, and/or an electronic control unit (ECU) connected with the biomedical sensor. The ECU may be configured to control the bladder assembly and the PEMF coil assembly, and/or to determine if a user occupying the seat is in a first state or a second state. The first state may correspond to one or more small user movements. Small user movements may include movements having magnitudes below a specified value or threshold. The second state may correspond to one or more large user movements. Large user movements may include movements having magnitudes above the specified value or threshold. The ECU may operate in a first mode when said user is in the first state and operate in a second mode when said user is in the second state.

A transmission system for providing sliding movement of a vehicle seat within a vehicle includes a dual output motor having a left-hand and right-hand motor output shafts, a left-hand bevel gearbox and a right-hand bevel gearbox operatively coupled to a respective one of the left-hand and right-hand output motor shafts, a left-hand long rail assembly comprising a left-hand power rail drive assembly slidably coupled to a left-hand fixed long rail and operatively coupled to the left-hand bevel gearbox and a right-hand long rail assembly comprising a right-hand power rail drive assembly slidably coupled to a right-hand fixed long rail and operatively coupled to the right-hand bevel gearbox. The dual output motor rotates the left-hand and right-hand motor output shafts resulting in each of the left-hand and right-hand power rail drive assemblies being transposed along the respective left-hand and right-hand fixed long rails.
