Abstract: A vehicle body structure having a pillar member maintains the shape of a pillar member in a substantially linear state when the pillar member deforms inward toward the passenger compartment during a side collision. The pillar member has a collision force converting structure that is constituted by the curved shape of the pillar member. When a side collision force is imparted to the pillar member, the collision force converting structure converts it into and maintains it as a force acting on the pillar member in the lengthwise direction of the pillar member. Thus, the collision force is absorbed as a lengthwise compressive load in the pillar member. A shape maintaining structure restricts the inward deformation of the pillar member 3 toward the passenger compartment and holds the pillar member in a substantially linear shape to increase the efficiency with which the collision load is transferred to the side roof rail and side sill.

Abstract: A vehicle body structure is configured that enables a cabin section and a chassis frame to move relative to each other and enables both strength of the vehicle body and the safety of the occupants during a collision to be ensured with good efficiency. The cabin section serves as the space in which the passengers reside. The chassis frame and cabin section are separate, independent structures connected through a displacement mechanism in such a manner that the chassis frame and cabin section can move separately relative to each other, when a collision occurs. As a result, transmission of the collision impact to the cabin section is alleviated in an effective manner and the strength of the cabin section and chassis frame can be increased.

Abstract: The vehicle body side structure is provided that comprises a front pillar, a center pillar, a rear pillar, a side sill, a roof side rail, and front and rear strengthening members. The center pillar further comprises an inner pillar member or portion coupled to the roof side rail and the side sill and an outer pillar member or portion disposed on the transversely outward side of the inner pillar member. The outer pillar member is coupled to the side sill a vertically approximate center portion of the inner pillar member. A main energy absorbing section is provided at a lower end portion of the outer pillar member. The front and rear strengthening members are coupled only to the outer pillar member of the center pillars. As a result, a load input during a side collision is dispersed and transmitted through the strengthening members and through the inner pillar member.

Abstract: A front vehicle body structure is configured to transmit and disperse loads imparted from a front of the vehicle body to a wider portion of the vehicle body for improving the energy absorption efficiency. A generally rectangular or C-shaped frame-like structural body is formed by a pair of upper front pillar portions, an upper cross dash portion and either the front roof rail or a pair of side roof rails. Forward-protruding box-cross-section parts are connected to the bottom end parts of the upper front pillar portions and the rear ends of hood ledge members. Lower front pillar portions are connected to the upper front pillar portions, the box-cross-section parts, the upper cross dash portion, and the side sills. The upper cross dash portion is arranged on the axes of the upper front pillar portions as seen in a side elevational view.

Abstract: A vehicle body structure is configured to convert a lateral-impact input to an input that acts on a pillar member in substantially a vertical direction of the vehicle body. The vehicle body structure has an input conversion structure configured to convert a side-impact input that acts inwardly on the pillar member in a substantially horizontal direction from the vehicle exterior to an input that is applied to the pillar member in the vertical direction of the vehicle body. Thus, the side-impact input can be converted as an input that is applied to the pillar member in the vertical direction of the vehicle body, so that the input can be absorbed as a compression load applied to the pillar member in the longitudinal direction, and deformation into the passenger compartment can be minimized.

Abstract: A vehicle front body structure includes a side-member front area 11F inclined outwardly in the width direction of a vehicle as directing ahead of the vehicle, a strength control mechanism C provided in the side-member front area 11F, a sub-side member 20 extending from the vicinity of a continuous base of the side-member front area 11F toward the front of the vehicle, substantially straight to an extension of a side-member rear area 11R. The front end of the sub-side member 20 is connected with the rear face of a bumper reinforcement 12. The sub-side member 20 is provided with a deformation-mode control mechanism D that allows the sub-side member 20 to be deformed inwardly in the width direction of the vehicle due to a collision input and interferes with a power unit P, forming an impact load transfer mechanism B.

Abstract: A front body structure includes a pair of side members 11 and a strength adjusting mechanism 50 arranged on a forward area 11F of each side member 11. By the strength adjusting mechanism 50, it is established that a maximum stress generated in a front part of each one of imaginary sections Ia-Ie continuing in the longitudinal direction of the forward area 11F becomes more than or close to a maximum stress generated in a rear part of the each one of imaginary sections. As a result, when the collision load is inputted to the front end of the side member 11 obliquely from the front, a collapse is induced from the front end of the forward area 11F toward the rear. Then, the collapse is transmitted to the rear part of the area 11F continuously, enhancing the absorbing efficiency of the collision energy.

Abstract: The vehicle body side structure is provided that comprises a front pillar, a center pillar, a rear pillar, a side sill, a roof side rail, and front and rear strengthening members. The center pillar further comprises an inner pillar member or portion coupled to the roof side rail and the side sill and an outer pillar member or portion disposed on the transversely outward side of the inner pillar member. The outer pillar member is coupled to the side sill a vertically approximate center portion of the inner pillar member. A main energy absorbing section is provided at a lower end portion of the outer pillar member. The front and rear strengthening members are coupled only to the outer pillar member of the center pillars. As a result, a load input during a side collision is dispersed and transmitted through the strengthening members and through the inner pillar member.

Abstract: The pillar structure to which the passenger cabin end of the hood ridge panel is connected, is arranged have different localized structural deformation resistances which buckle/deform in a manner which causes the hood ridge panel to reorient in response to a vehicle structure deforming force being applied to the front of the vehicle during a collision, and results in the force, which passes through the hood ridge panel, being redirected by a load-converting and transmitting member included in the pillar, up and along an upper rearwardly angled upper portion of the pillar. This force redirection produces sufficient resistance to induce compressive bucking in the structure forward of the passenger cabin and thus attenuate damage to the cabin structure.

The pillar has an upper end joined to a side roof rail and a lower end joined to a side sill. At a transition point between the upper and lower ends, the pillar defines a boundary between an upper structure portion and a lower structure portion. The upper structure portion extends between the upper end and the predetermined point. The lower structure portion extends between the predetermined point and the lower end. The upper and lower structure portions implement reinforcement and deformation permission measures, respectively.
