A support driver for a seat and a support assembly including the same that is using a tube and a structure of a mat that is moved by an inflation and a deflation of the tube. According to an embodiment of the present disclosure, the support driver coupled to a seat frame includes: a support portion coupled to the seat frame; a tube coupled to the support portion; and a mat coupled to the support portion so as to allow the mat to be movable in a direction that is away from the support portion or in a direction that is adjacent to the support portion, with the tube being provided therebetween, in which the tube is configured to push the mat by being inflated according to an operation of a pump that is connected to the tube by a hose.

A backrest of a vehicle seat comprises a backrest frame, a support plate fixed to the backrest frame, and at least one vibrating device. Each vibrating device is fixed to the support plate by means of at least one damping element. Preferably, each vibrating device is fixed on a face of the support plate opposite to the face intended to be oriented towards an occupant of the seat, at least a portion of each vibrating device being received in a respective through-hole in the support plate.

A motor vehicle seat, having a seat massage system which has one, or a plurality of, fluid-fillable massage bladder(s), has a cushion which comprises a first side facing the seat occupant and a second side opposite the first side. The massage bladder(s) is/are arranged on the second side of the cushion such that filling the massage bladder(s) causes a pressure of the filled massage bladder(s) on pressure regions of the cushion and thus a deformation of the cushion. At least one of the pressure regions is surrounded by a recess present in the cushion.

A vehicle seat that includes: at least one support element defining a cavity, an air pump, and at least one olfactory diffuser arranged in the cavity and fluidly connected to the air pump, the olfactory diffuser having an outer casing defining an inner volume, the outer casing defining an air inlet and an air outlet, the olfactory diffuser further having at least one olfactory substance carrier arranged in the inner volume defined by the outer casing. The air pump causes the circulation of a flow of air through the inner volume from the air inlet to the air outlet toward the outside of the cavity.

The present technology relates to a seat for a moving device, a seat control device, and a seat control method capable of improving comfort of a seat with a simple configuration. A seat for a moving device includes a left adjustment portion configured to adjust hardness of a left gluteal contact portion including a portion assumed to be in contact with a left gluteal portion of a user on a seat surface and a right adjustment portion configured to adjust hardness of a right gluteal contact portion including a portion assumed to be in contact with a right gluteal portion of the user on the seat surface. The present technology can be applied to, for example, a system that controls automatic driving.

Various examples relate to electrically actuated valves. Various examples relate to actuators to be used for valves, e.g., shape—memory alloy actuators or solenoid actuators (151) or piezoelectric actuators. Various examples relate to a modular concept in which a valve can be formed by attaching an actuator component (601) to a housing. Various examples relate to a further modular concept in which multiple valve blocks, each valve block including one or more valves, can be fluidly coupled with each other.

A fluid bladder valve for a pneumatic vehicle seat adjustment device is disclosed. The valve comprises a first chamber configured to be connected to a fluid source, a second chamber configured to be connected to the fluid bladder, a third chamber configured to be connected to an environment, a fourth chamber connected to the first chamber via a first fluid passage, connected to the second chamber via a second fluid passage, and connected to the third chamber via a third fluid passage; and an actuator comprising a membrane disposed in the fourth chamber and an actuator element disposed in the third chamber and coupled to the membrane and configured to move the membrane between a first position wherein the first fluid passage is opened and the third fluid passage is closed, and a second position wherein the first fluid passage is closed and the third fluid passage is opened.

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.

An occupant protection apparatus includes a driver. The driver includes a drive unit, a support shaft, a movable seat pan supported by the support shaft such that the movable seat pan is inclinable in a front-rear direction, a guide groove, a movement pin that is movable along the guide groove, a link that couples the movable seat pan to the movement pin, and an energy absorber. The guide groove includes a first guide groove portion in which the movement pin moves when the movable seat pan is inclined rearward and a second guide groove portion in which the movement pin moves when the movable seat pan is inclined forward. The energy absorber is configured to absorb at least part of a forward load from an occupant when the movement pin moves in the second guide groove portion.

An actuator arrangement for an electromagnetically actuatable valve comprises a housing having a first wall, and a second wall situated opposite the first wall, a solenoid armature, with first and second axial armature end surfaces facing toward the first and second housing walls respectively, movable along an axis between a first position, where the first end surface makes contact with the first wall, and a second position, where the first end surface is away from the first wall. A damping element of an elastomer material extends from the second end surface toward the second wall and contacts the second wall in the first and second positions of the solenoid armature, A stop element of an elastomer material extends from the second end surface toward the second wall and, in the first position, is away from the second wall and, in the second position, contacts the second wall.
