Abstract
A body structure of a vehicle having a cabin C and a compartment F.C, R.C is provided. The body structure includes a pair of laterally spaced side frame members 13,14 extending forwardly of the cabin at sides of the compartment. The side frame members 13,14 include widthwise rigidity lowering sections 21,52, respectively, to allow inward bending of a rear section 13R, 14R of each side frame member in a widthwise direction to provide an increased collapsible stroke for thereby effectively absorbing an energy in a wide range typically in a frontal impact.
Claims27
A body structure of a vehicle, comprising:
- a cabin;
- a compartment in close proximity to the cabin;
- first frame members provided in the compartment, laterally spaced relative to each other in a widthwise direction of the body structure, and longitudinally extending in a longitudinal direction of the body structure from the cabin;
- and
- a widthwise rigidity adjustment section provided in each of the first frame members and having a non-symmetric strength distribution in the widthwise direction,
- wherein a part of the cabin is formed by second frame members, and each of the first frame members is provided with a front side member that has the widthwise rigidity adjustment section, and the widthwise rigidity adjustment section weakens an inside rigidity of the front side member.
A body structure of a vehicle comprising a cabin, side frame members, and a compartment in close proximity to the cabin, wherein each of the side frame members, which are laterally spaced and longitudinally extending in the compartment, has a section that weakens an inside rigidity of each of the side frame members.
A body structure of a vehicle, comprising:
- a cabin;
- a compartment in close proximity to the cabin;
- frame members provided in the compartment, laterally spaced relative to each other in a widthwise direction of the body structure, and longitudinally extending in a longitudinal direction of the body structure from the cabin;
- and
- means for adjusting a widthwise rigidity in each of the frame members to weaken an inside rigidity of each of the side frame members by a non-symmetric strength distribution thereof in the widthwise direction.
