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.

Abstract: A vehicle comprises a bumper reinforcement extending in a vehicle width direction and a shock absorbing member fixed to a front face of the bumper reinforcement and extending in the vehicle width direction along the bumper reinforcement. The shock absorbing member comprises a base portion extending vertically along the front face of the bumper reinforcement and a projection portion extending forward from a lower end portion of the base portion and being resiliently-downward deformable relative to the base portion. Thus, the vehicle comprising the shock absorbing member provided in front of the bumper reinforcement with the leg-flicking function for the pedestrian protection can be provided.

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.

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.
