  • Patent number: 8016340
    Abstract: A floor spacer for a vehicle constituted of an expanded resin molded article which can simultaneously satisfy sound absorbing performance while satisfying desired compression strength and reduction in weight is provided. A floor spacer A for a vehicle is constituted of a floor spacer main body 10 constituted of an expanded resin molded article having flat plate portions 12a and 12b to be on an inner side of a compartment, and a plurality of ridges 13a and 13b vertically provided at back surfaces of the flat plate portions 12a and 12b on a floor frame side, and a layer constituted of a sound absorbing material 20 formed to fill spaces 14a and 14b formed between the aforesaid ridges 13a and 13b. Through-holes 15 may be formed in the flat plate portions 12a and 12b of the floor spacer main body 10, and fastening holes 16 which a part of the sound absorbing material 20 enters may be formed in the ridges 13a and 13b.

  • Patent number: 7900994
    Abstract: A pad for absorbing an impact on leg portions excellent in impact absorbing performance at a time of collision of a vehicle and the like, and a floor spacer for a vehicle are provided. A pad 1 for absorbing an impact on leg portions has a plurality of ridges 3, 3, . . . on a bottom surface to be on a vehicle body side when placed in a vehicle, and is constituted of expandable beads. A floor spacer 10 is constituted of the pad 1 for absorbing an impact on leg portions and a horizontal pad 2. The ridge 3 has a wide portion 32 which becomes relatively wide from a midpoint in its longitudinal direction. The heel portions of the feet of an occupant are placed on the region of the wide portion 32.
