  • Publication number: 20240286537
    Abstract: An apparatus for tilting a seat cushion of a rear seat of a vehicle includes: a fixing member connected to a vehicle body and being shaft-rotated while a location of the fixing member is fixed; a tilting motor coupled to the fixing member; and a linkage connecting the tilting motor and the seat cushion of the seat, and operable to move a front end of the seat cushion vertically when the tilting motor is moved. The front end of the seat may be moved vertically so as to implement a tilting function, and a tilting apparatus of the rear seat may be operated simultaneously with occurrence of a collision or immediately before a collision so as to adjust the front end of the seat cushion upward, so that movement of a passenger in an accident can be restricted.

  • Publication number: 20240288124
    Abstract: In a high pressure gas charging system and method, the system includes a charging container, a fluid supply part and a high pressure charging part. A high pressure gas is charged in the charging container. The fluid supply part is connected to a first side of the charging container, and is configured to supply incompressible fluid into the charging container before charging the high pressure gas. The high pressure charging part is connected to a second side of the charging container, and is configured to charge the high pressure gas into the charging container in which the incompressible fluid is already supplied. The incompressible fluid is supplied to the charging container until an inner pressure of the charging container reaches a predetermined pressure, and the incompressible fluid is removed to outside through the fluid supply part as the high pressure gas is charged into the charging container.
