  • Patent number: 11072305
    Abstract: There is provided a passenger seat air bag having a portion which is unfolded to a side toward a center side of a vehicle in which a pressure difference in the portion is suppressed. A passenger seat air bag includes a front unfolding portion which is unfolded in front of the passenger seat, and a side unfolding portion which is in communication with the front unfolding portion and which is unfolded to side, of the passenger seat, nearer to a center of the vehicle. A horizontal tether is provided in the side unfolding portion in an arrangement which is approximately horizontal during unfolding. When unfolding gas is injected from the front to the air bag, because the horizontal tether does not block flow of the unfolding gas, pressure us the side unfolding portion is made uniform.

  • Patent number: 10899281
    Abstract: A backing section is adjacently disposed in front, in a front-and-rear direction of the vehicle, of an upper portion of a door section of a glove box, and inhibits the door section from moving further forward from a position at a time of the glove box being in a closed state. A reinforcing bead for enhancing rigidity is formed on a contact surface of the backing section with the door section. When a vehicle comes into a frontal collision, and knees K of a passenger collide with the backing section, the backing section becomes difficult to deform. If the backing section does not deform, a reaction force from the backing section is transmitted to the knees K via the door section, and forward movement of the knees K is restrained.

  • Patent number: 10889332
    Abstract: A connecting member includes at least one of a tilting allowing structure configured to allow tilting of the connecting member, a buckling allowing structure configured to buckle at a first portion of the connecting member and a bending deformation allowing structure configured to allow the connecting member to be bent at a second portion of the connecting member. When a force equal to or larger than a predetermined force is loaded on the connecting member, an upper portion of an instrument panel can be deformed without being resisted by the connecting member. Further, the connecting member is constructed such that the connecting member does not buckle when a force smaller than the predetermined force is loaded on the connecting member. Therefore, the upper portion of the instrument panel can be prevented from being deformed downward at a normal operating state.

  • Publication number: 20200032051
    Abstract: Provided is a polycarbonate resin composition having the following features: even when the composition is retained in a molding machine at a high temperature exceeding 340° C., the composition shows little yellowing and hence maintains a satisfactory color tone; and even when a molded article obtained by molding the composition after the composition has been retained under a high-temperature condition undergoes thermal history, the molded article shows a small change in color tone with time and is hence excellent in long-term stability of its optical characteristics. The polycarbonate resin composition includes predetermined amounts of a polycarbonate resin (A), a specific polyether compound (B), and a specific antioxidant (C).
