  • Patent number: 10562481
    Abstract: An airbag package of an airbag for head protection includes a rolled portion formed by rolling a skin material of the airbag as laid flat, and a compressed region in which a void space formed at the center of the cross-sectional surface of the rolled portion has been crushed due to compression. The rolled portion includes, in the cross-sectional surface, an upper layered portion, a lower layered portion, and a pair of side layered portions that are disposed around the center of the cross-sectional surface of the rolled portion and each have layers of the skin material. In the compressed region, each of the side layered portions bends generally at the center in an up and down direction such that the bent regions butt against each other and are packed between the upper layered portion and the lower layered portion in such a manner as to fill the void space.

  • Publication number: 20190181663
    Abstract: A smoothing unit smooths a detected voltage of each power storage block based on previous data during a certain period. A calculator calculates a difference between a smoothing voltage of one power storage block in the n power storage blocks and a representative value of the smoothing voltages of the other power storage blocks or all the power storage blocks. A determination unit determines a power storage block whose difference against the representative value enlarges more than or equal to a set value during a predetermined period as a power storage block containing an abnormal power storage cell.
