  • Patent number: 12054080
    Abstract: In a vehicle seat frame, a connection member that connects left and right links together in a seat left-right direction is disposed below a rear portion of a cushion pan included in a seat cushion frame. A sloped surface sloped with a downward gradient toward a seat rear side is formed at a lower surface of the rear portion of the cushion pan. The sloped surface of the cushion pan slides in a seat rearward and diagonally downward direction relative to the connection member when the cushion pan deforms in a seat downward direction under load from the occupant during a head-on collision of the vehicle.

  • Patent number: 11312790
    Abstract: The present invention provides a method for producing pentosan polysulfate, the method including a first step of obtaining an acidic xylooligosaccharide from a plant-derived raw material, and a second step of obtaining pentosan polysulfate from the acidic xylooligosaccharide. The first step includes a step of depolymerizing the plant-derived raw material. The second step includes a step of sulfating the acidic xylooligosaccharide. The method further includes a deacetylation step of adding a base to achieve a pH of 11 or higher. The deacetylation step is a step performed after the depolymerization step. The production method of the present invention can provide pentosan polysulfate having a low acetyl group content, and also produce pentosan polysulfate with a high yield inexpensively and efficiently.
