  • Patent number: 5176424
    Abstract: An automobile seat assembly includes a seat cushion subassembly and a seat back subassembly coupled with the seat cushion subassembly to represent a generally L-shaped configuration. A holding device is installed in the seat cushion subassembly and is deformable in response to the sitting of a seat occupant on a sitting area of the seat cushion subassembly and holds the sitting area in a deformed shape resulting from the seat occupant sitting on the sitting area. An actuating device installed in the seat cushion subassembly actuates the holding device. A detecting device detects the actual sitting position of the seat occupant on the sitting area. A control device is operable to operate the actuating device a predetermined time after the detecting device has detected the actual sitting position of the seat occupant on the sitting area.

  • Patent number: 4931340
    Abstract: A honeycomb panel structure for thermal and acoustic insulation and for load bearing capability has a honeycomb panel which comprises a honeycomb core laminated with two facing plates, and a pair of housings. Each housing has a channel to engage and support a edge of the honeycomb panel. A first neutral axis passes through the center of gravity of the honeycomb panel and extends in the direction of the panel. A second neutral axis passes through the centers of gravity of the housings and extends parallel to the first neutral axis. The first and second neutral axes are spaced apart in a vertical direction so that the structure has much higher flexural rigidity.
