  • Patent number: 9242675
    Abstract: According to a vehicle-body front structure, when a collision load caused at the time of a front end collision is input into a front part of a connecting member fixed to a front end of an apron upper member, a protruding member protruding outwardly in a vehicle width direction from a front part of a side-member main body is able to interfere with the front part of the connecting member from a vehicle rear side. This makes it possible to improve a transmission efficiency of the collision load between the connecting member and the front side member. Besides, the front part of the connecting member is reinforced by a bulk head, thereby making it possible to restrain the front part from being deformed by the collision load.

  • Publication number: 20150360632
    Abstract: A vehicle body front section structure capable of suppressing deformation of a vehicle body in a small overlap collision is obtained. A vehicle body front section structure includes a front side member with a crash box attached to a vehicle front end, a coupling member that is interposed between and joined to the crash box and the front side member at a vehicle front end side, and that is joined to a fender apron section at a vehicle rear end, and a spacer that is disposed at a portion overlapping with the front side member in a vehicle vertical direction between the front side member and the coupling member.

  • Publication number: 20150360633
    Abstract: A vehicle front section structure includes a front side member that is formed with a front flange at a vehicle front-rear direction front end; a crash box that is joined to the front flange at a rear flange formed at a vehicle front-rear direction rear end; and a coupling member that is joined to a fender apron section at a vehicle rear end. The coupling member includes a joining plate formed at a vehicle front end side joined to the front flange in an interposed state between the front flange and the rear flange, with a front end side of a portion of the coupling member positioned at a vehicle width direction outer side of the front side member angled such that in plan view a rear side is separated further to the vehicle width direction outer side from the front side member than the vehicle front side.
