This air pump device is provided with: an electric pump unit including a pump mechanism and a motor; a case; and a vibration-proof member. The pump mechanism and the motor are arranged side by side in the axial direction of the motor. The pump mechanism has an inlet and an outlet at an end in the axial direction on the opposite side of the motor. The case has a first wall and a second wall which are located on opposite sides in the axial direction of the motor and which face the electric pump unit. The vibration-proof member is provided with: a first axial vibration-proof unit interposed between the electric pump unit and the first wall; and a second axial vibration-proof unit interposed between the electric pump unit and the second wall. The first axial vibration-proof unit covers the inlet.

A vehicle seat comprising: a seat base comprising a rigid frame, a flexible covering layer, as well as a cushioning layer interposed between the flexible covering layer and the frame, a backrest comprising a rigid frame, a flexible covering layer, as well as a cushioning layer interposed between the flexible covering layer and the frame, and a haptic system, comprising: at least one independent set each comprising at least one pneumatic haptic element, positioned at the backrest and/or the seat base, and at least one independent set each comprising at least one electromechanical haptic element, positioned at the backrest and/or the seat base.

Disclosed herein are an intelligent massage chair and a control method thereof. The intelligent chair includes a sensing unit mounted on the intelligent chair, and including at least one sensor, and a controller. The controller performs a control to determine a user's body condition based on the information about the user's body acquired through the sensing unit, and to determine an operation mode based on the determined user's body condition, and to add the information about the user's body, when it is determined that the determined operation mode is not an optimum operation mode for the user. One or more of an intelligent massage chair, an autonomous vehicle, a user terminal and a server of the present disclosure can be associated with artificial intelligence modules, drones (unmanned aerial vehicles (UAVs)), robots, augmented reality (AR) devices, virtual reality (VR) devices, devices related to 5G service, etc.

A pneumatic bladder arrangement comprises a plurality of bladders arranged in an array of rows and columns, wherein the array comprises a first array section and a second array section with the first and second array sections each comprising at least one row of bladders. The pneumatic bladder arrangement may be used in a support apparatus for a seat, in particular for a backrest of a seat.

A comfort element for a vehicle includes an actuator for carrying out a comfort function, a comfort-element-internal store configured to drive the actuator and/or a coupling device for coupling to a comfort-element-external store configured to drive the actuator. The comfort element further includes a data interface for coupling to an operating unit.

A device and a method for controlling a seat of a vehicle includes a detector for detecting vehicle environment information, a vibration generator mounted on the vehicle seat to generate the seat vibration, and a controller electrically connected to the detector and the vibration generator, and the controller detects seat environment information through the detector, determines a weight and a sitting posture of a user seated in the vehicle seat based on the seat environment information, determines a vibration pattern and a vibration excitation force based on the weight and the sitting posture of the user, and generates the seat vibration by controlling the vibration generator based on the determined vibration pattern and vibration excitation force.

A seat that includes an upper surface, a lower surface, one or more pressure sensors communicatively coupled to a controller, and a plurality of artificial muscles disposed between the upper surface and the lower surface. Each of the plurality of artificial muscles is communicatively coupled to the controller. Each of the plurality of artificial muscles includes a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair positioned in the electrode region of the housing. The electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region.

The main cushion (3) of an automobile seat (e.g. the seat pan cushion, or a backrest cushion) is provided with a shield (2). The shield surrounds at least part of the lateral sides of the main cushion and is formed of a less compressible (i.e. harder) foam than the main cushion, such that when the seat is upholstered, creases in the upholstery are reduced/prevented and gapping is avoided.

An occupant support system includes a vehicle seat and an electronics system for the vehicle seat. The electronics system includes a sensor system configured to obtain sensor data and a computer coupled to the sensor system to process the sensor data and perform a predetermined action using the sensor data.

A device for reducing kinetosis-related disorders of an occupant of a vehicle includes a vehicle seat with a headrest. A seat belt is assigned to the vehicle seat which is configured to increase a connection of the occupant to the vehicle seat before an onset of an acceleration. An actuator system is coupled to the headrest which is configured to move the headrest automatically, at least in sections, counter to an expected direction of an acceleration of a head of the occupant before the onset of the acceleration. The seat belt is tightenable by a reversible belt tensioner before the onset of the acceleration.
