  • Patent number: 8950778
    Abstract: The strength of an instrument panel member (12) at a portion thereof between a steering shaft support part (16) and a linking part (13) on the side near a steering shaft (11) is set lower than the strength of the instrument panel member (12) at a portion thereof between the steering shaft support part (16) and a linking part (14) on the far side from the steering shaft (11), with respect to a load input through the linking part (13) on the side near the steering shaft (11) in the vehicle body front-rear direction. The above configuration makes it possible to suppress movement of a steering wheel inward in the vehicle width direction to thereby securely restrain a vehicle occupant by an airbag at the time of a vehicle frontal collision.

  • Patent number: 8720627
    Abstract: A battery is arranged at a specified position which is located on an outside of a front side frame in a vehicle width direction and between a front wheel and a crush can in a vehicle longitudinal direction. Accordingly, the battery can be positioned properly at a front portion of a vehicle so that the battery may not receive any improper thermal influence from an engine or a motor and not hurt the function of impact absorption in a vehicle frontal collision.

  • Patent number: 8393673
    Abstract: Part of a front side frame is configured to be deformed so as to bend outwardly, in a vehicle width direction, by a collision load in a vehicle frontal collision. A sub frame provided at a lower portion of a front vehicle body is joined to the front side frame via a reinforcement. A front portion of the reinforcement is located at a position which corresponds to a bending portion of the front side frame which is to be deformed so as to bend outwardly, in the vehicle width direction, by the collision load in the vehicle frontal collision. Accordingly, the bending of the front side frame at its bending portion when the collision load acts in the vehicle frontal collision can be promoted, so that the collision load against passengers can be decreased securely.

  • Patent number: 8267429
    Abstract: A positioning pin and a bolt hole positioned near this pin are provided at a plate-shaped rear-portion attachment face portion of a suspension cross member. A positioning hole having the positioning pin inserted thereinto and a bolt hole positioned near this positioning hole are provided at a tunnel frame on the side of a vehicle. The rear-portion attachment face portion and the tunnel frame are fastened by a bolt inserting into the bolt holes together with a nut. Accordingly, the support rigidity of the suspension cross member during the normal vehicle traveling can be secured and the smooth retreat of the power unit to restrain the collision load from having bad influence on passengers in the vehicle frontal collision can be achieved.

  • Patent number: 7887123
    Abstract: A front side frame includes a bend portion which is operative to bend outward when an impact load acts on the front side frame from ahead. The bend portion is provided in a specified location such that the bend portion in a bending state substantially contacts a damper of the suspension from a vehicle front side. Accordingly, a rear end of the front side frame can be prevented properly from moving back when the impact load acts on the front side frame from ahead.

  • Publication number: 20090243336
    Abstract: A reinforcement member is provided inside a frame member at a space which includes a bend portion operative to bend in such a manner that the reinforcement member comes to contact an inner face of an inside side face portion of the frame member as the frame member bends at the bend portion. Accordingly, the amount of energy absorption even after the bending start of the frame member can be properly increased.
