  • the seat cushion does not a device for regulating pressure of the body of an occupant.
  • the present invention provides a support device for a seat in a vehicle which supports the body of an occupant in a stable manner.
  • An exemplary embodiment of the present invention provides a support device for a seat in a vehicle which includes: a main chamber which is interposed between a seat cushion and a base plate in which the main chamber is disposed below the seat cushion and is deployed by the movement of gas therein when an occupant sits on the seat cushion so as to be deformed in conformity with a hip line and a body shape of the driver or the passenger; a support blade which adheres onto the main chamber and is extended along both sides of the main chamber so as to enclose both sides of the pelvis of the occupant when the main chamber is deployed; a compressing member which is operated by the manipulation of a switch, which is disposed near the occupant seat, so as to supply gas into the main chamber; and a regulation valve which is installed to a tube interconnecting the compressing member and the main chamber so as to regulate gas supply to and gas discharge from the main chamber according to the manipulation of the switch.
  • the main chamber comprises thermoplastic polyurethane.
  • the main chamber may be formed such that inner surfaces of a main chamber body are fixed to one another along a longitudinal direction thereof.
  • a plurality of ribs may be formed on an outer surface of the main chamber along a horizontal direction to be spaced from one another such that the main chamber is deployed when the gas is supplied to the main chamber from the compressing member.
  • the length of the ribs may become longer as it approaches both ends of the main chamber from a center thereof.
  • the ribs may be arranged to be spaced from one another by a constant distance.
  • the support blade may include a center part which is formed so as to be flexibly deformed in conformity with a shape of a rounded hip of the occupant, and support parts which are respectively connected to both ends of the center part and the width of which are expanded so as to sufficiently support both sides of the pelvis of the occupant.
  • the support blade may be formed such that the thickness of the support part is greater than the thickness at a center part.
  • the support blade which is coupled to the main chamber may be installed to a seat cushion of a front passenger seat or a rear passenger seat.
  • FIG. 1 is a drawing showing a support device of a seat for a vehicle according to an exemplary embodiment of the present invention.
  • FIG. 2 is a drawing showing a support blade of a support device of a seat for a vehicle according to an exemplary embodiment of the present invention.
  • FIG. 3 a and FIG. 3 b are drawings showing operation states of a support device of a seat for a vehicle according to an exemplary embodiment of the present invention.
  • FIG. 4 is a drawing showing another operation state of a support device of a seat for a vehicle according to an exemplary embodiment of the present invention.
  • a support device for a seat in a vehicle includes: a main chamber 100 which is interposed in which a seat cushion 3 and a base plate 4 which is disposed below the seat cushion 3 .
  • the main chamber 100 is deployed by movement of gas therein when the driver 2 or the passenger sits on the seat cushion 3 so as to be deformed in conformity with a hip line and a body shape of the driver or the passenger.
  • a support blade 200 which adheres onto the main chamber 100 and is extended in both sides of the main chamber 100 so as to enclose both sides of the pelvis of the driver 2 or the passenger when the main chamber 100 is deployed.
  • a compressing member 300 which is disposed near a driver seat, is operated by manipulation of a switch 10 , so as to supply gas into the main chamber 100 .
  • a regulation valve 400 which is installed to a tube 20 connects the compressing member 300 and the main chamber 100 so as to regulate gas supply and gas discharge from the main chamber 100 according to the manipulation of the switch.
  • the main chamber 100 is made of thermoplastic polyurethane.
  • Thermoplastic polyurethane is a specific type of thermoplastic and has excellent anti-abrasion, flexibility, and tensile strength.
  • Thermoplastics are materials that soften or melt when heated and harden when cooled.
  • Thermoplastic polymers consist of long polymer molecules that are not linked to each other.
  • Thermoplastics include, but are not limited to, polyethylene, polypropylene, polystyrene, polyester, polyvinyl chloride, acrylics, nylons, spandex-type polyurethanes, and cellulosics.
  • the main chamber 100 is formed such that the inner surfaces of a main chamber body 101 are fixed to one another along a longitudinal direction. It is preferable that the fixing step occurs by ultrasonic welding or heat welding.
  • a plurality of ribs 500 are formed on an outer surface of the main chamber 100 along a horizontal direction and are spaced from one another such that the main chamber 100 is deployed when gas is supplied to the main chamber 100 from the compressing member 300 .
  • the length of the ribs 500 may become longer as it approaches both ends of the main chamber 100 from a center thereof. Additionally, the ribs 500 are arranged to be spaced from one another by a constant distance.
  • the support blade 200 includes a center part 210 which is formed so as to be flexibly deformed in conformity with the shape of a rounded hip of the driver 2 or the passenger.
  • Support parts 220 which are respectively connected to both ends of the center part 210 and the width of which are expanded so as to sufficiently support both sides of the pelvis of the driver 2 or the passenger.
  • the support blade 200 is formed such that a thickness t′ of the support part is greater than a thickness t of a center part.
  • the compressing member 300 may be realized by a pump which compresses gases including air.
  • the support blade 200 which is coupled to the main chamber 100 may be installed on a seat cushion of a front passenger seat or a rear passenger seat. Additionally, the support blade 200 may also be installed in a seat in the back of a driver seat, a front passenger seat, and a rear seat.
  • the driver 2 when the driver 2 is sitting on the seat cushion 3 of a driver seat, the driver 2 turns on the switch 10 such that the seat is adjusted in conformity with the seat cushion 3 and the body shape of the driver 2 .
  • Electric power is applied to the compressing member 300 in response to the manipulation of the switch such that gas generated in the compressing member 300 is supplied to the main chamber 100 via the regulation valve 400 .
  • gas passes through the regulation valve 400 which is supplied to an inner space of the main chamber 100 through the tube 20 , so the main chamber 100 is deployed, and at this time, both sides of the main chamber 100 are expanded toward an upper direction by the ribs 500 formed in the main chamber 100 .
  • the main chamber 100 is deployed in conformity with a line of the hip of the driver 2 , thereby supporting the body of the driver 2 .
  • the center part 210 of the support blade 200 which is disposed on the main chamber 100 is formed in a lattice shape so as to be flexibly deformed, thereby allowing the main chamber 100 to smoothly deform in the deployment direction.
  • Imaginary pressure acting on the main chamber 100 by the driver 2 is shown by the arrow, and both ends of the support part 220 of the support blade 200 are moved in directions of the arrows so as to sufficiently support both sides of the pelvis of the driver 2 by the deployment operation of the main chamber 100 , thereby enclosing both sides of the pelvis of the driver 2 .
  • the driver 2 manipulates the switch so as to turn off the operation of the compressing member 300 . If the operation of the compressing member 300 is turned off, the gas is not supplied any more through the regulation valve 400 , so the state shown in the drawing is maintained.
  • the seat cushion 3 is deformed by the operations of the main chamber 100 and the support blade 200 , so that the hip 2 a of the driver 2 can be stably supported.
  • the driver 2 may manipulate the switch such that gas is discharged to the outside via the regulation valve 400 .
  • the support blade 200 which is coupled to the main chamber 100 and is installed only to the driver seat in the embodiment of the present invention, it can also be installed to a seat cushion of a front passenger seat or a rear seat and in a seat in the back of a driver seat, a front passenger seat, and a rear seat.
