  • Patent number: 11938849
    Abstract: A seat for a vehicle having a fold-and-dive function is proposed. When a seatback is rotated forwards and folded, a seat cushion is moved down, so the fold-and-dive function of the seat is realized. When a full-flat mode is realized by the reclining operation of the seatback, a rear end of the seat cushion is moved up, so a step between the seat cushion and the seatback can be significantly reduced or eliminated. Furthermore, a front link connecting a back cushion interlocking frame and a cushion fixing bracket to perform the fold-and-dive function is installed to have directivity where it is inclined rearwards, thus preventing a submarine phenomenon of the seat in the event of a forward collision.

  • Patent number: 11936075
    Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.
