  • Patent number: 9327675
    Abstract: A pair of right-and-left brackets which extend obliquely downward and forward from respective front portions of a pair of right-and-left side frames are provided. A stiffener which extends in a vehicle width direction below a bumper beam is attached to respective front ends of the pair of right-and-left brackets. The stiffener is configured such that its front end portion slants downward and forward and has an open cross section, and its rear end portion thereof has a closed cross section. An obstacle can be prevented from coming in below a vehicle-body front portion, and also the sufficient energy absorption in a collision and the prompt flicking-up of an obstacle can properly achieved.

  • Patent number: 9254801
    Abstract: A protecting member comprises a pair of right-and-left brackets extending obliquely downward and forward from front portions of a pair of right-and-left side frames and a stiffener extending in a vehicle width direction below a bumper beam and attached to front ends of the brackets. The stiffener has a closed cross section extending in the vehicle width direction, and an upper face of its central portion in the vehicle width direction has a concaved portion. A lower face of the stiffener extends horizontally substantially straightly. It is preferable that the closed cross section of the central portion of the stiffener be configured such that its vertical distance is relatively small and its longitudinal width is relatively large, compared with the other part of the stiffener.

  • Patent number: 9233662
    Abstract: A protecting member includes a pair of right-and-left brackets which extend obliquely downward and forward from front portions of a pair of right-and-left side frames and a stiffener which extends in a vehicle width direction below a bumper beam and attached to front ends of the pair of right-and-left brackets. The protecting member has a load/deformation characteristic including a first stage from a collision start, a second stage after the first stage, and a third stage after the second stage. Herein, the first stage is set so as to restrain the obstacle from coming in below a vehicle-body front portion, the second stage is set so as to absorb collision energy to restrain a local deformation of the obstacle, and the third stage is set so as to flick the obstacle up.
