  • Patent number: 9663006
    Abstract: A vehicle seat provided in a vehicle includes a headrest with a pad in which an insert member is provided at a portion at which a head of an occupant is received. The insert member has rigidity that is higher than rigidity of the pad. When a rear-side collision occurs in the vehicle in a state in which the head of the occupant is away from the headrest and an inertia force applied to the occupant, the insert member allows the head of the occupant to sink into the headrest after the head of the occupant comes in contact with the headrest.

  • Patent number: 9505913
    Abstract: A polylactic acid resin composition containing a polylactic acid resin, glass fibers having an average aspect ratio (average fiber length/average fiber diameter) of 5 or more, and a metallic pigment, wherein the glass fibers are contained in an amount of from 2 to 35 parts by mass, and the metallic pigment is contained in an amount of from 0.1 to 8 parts by mass, based on 100 parts by mass of the polylactic acid resin. Since the polylactic acid resin composition of the present invention has excellent moldability, and is capable of providing a molded article with high designability, including a transparent surface layer and an inner layer with a lamellar texture in the nashiji patterns, the polylactic acid resin composition can be suitably used in various industrial applications, such as daily sundries, household electric appliance parts, packaging materials for household electric appliance parts, and automobile parts.
