Abstract: A pair of rear side frames respectively comprise front bending-promotion portions, middle bending-promotion portions and rear bending-promotion portions which cause the rear side frames to bend inward, in a vehicle width direction, in a trough-folding shape in a rear collision of a vehicle, and a longitudinal distance L2 between the front bending-promotion portions and the middle bending-promotion portions is set to be longer than a longitudinal direction L1 between the middle bending-promotion portions and the rear bending-promotion portions. Thereby, there is provided a rear vehicle-body structure of an automotive vehicle which can properly absorb a collision load at a vehicle-body rear portion, even if a rear side frame is made from material which may not cause smooth bucking of the rear side frame.
Abstract translation: 一对后侧框架分别包括前弯曲促进部分，中间弯曲促进部分和后弯曲促进部分，其使后侧框架在车辆宽度方向上向内弯曲，在后方的槽折叠形状 车辆的碰撞以及前部弯曲促进部和中间弯曲促进部之间的纵向距离L2被设定为比中间弯曲促进部和后部弯曲促进部之间的长度方向L1长。 因此，提供了能够适当地吸收车体后部的碰撞载荷的机动车辆的后车身结构，即使后侧框架由不会引起后侧的平滑弯曲的材料制成 帧。

Abstract: A recessed portion is formed at a frame member provided at a rear portion of a vehicle body and having a closed cross section extending in a vehicle longitudinal direction, wherein the recessed portion is configured such that a lower face of the frame member is recessed upwardly and a damper is inserted into and fixed to the recessed portion. Closed cross sections are formed inside the frame member at a position corresponding to the recessed portion. These closed cross sections are configured to branch off from the closed cross section outwardly and inwardly relative to the damper. A reinforcing member is fixed to the frame member and a wheel house inner at the position corresponding to the recessed portion such that a space is formed at a corner portion of these.

Abstract: A vehicle-body structure comprises a pair of right-and-left crash cans provided at an end portion of a vehicle body, being spaced apart from each other in a vehicle width direction, a bumper reinforcement extending in the vehicle width direction and connecting respective tip portions of the crash cans, set plates interposed between each of the crash cans and a vehicle-body side frame, wherein each of the crash cans is fixed to the vehicle-body side frame via the set plates, and a brace extending obliquely, in a plan view, from an inward side, in the vehicle width direction, of the crash can or the set plate to the bumper reinforcement such that a space is formed, in the vehicle with direction, between the brace and the crash can. The brace is fixedly joined to a lower face of the bumper reinforcement.

Abstract: A recessed portion is formed at a frame member provided at a rear portion of a vehicle body and having a closed cross section extending in a vehicle longitudinal direction such that a part of a lower face of the frame member is recessed upwardly, where a damper of a rear suspension is inserted and fixed. Closed cross sections are formed at a position corresponding to the recessed portion, in a longitudinal direction, of the frame member. The closed cross sections are configured to branch off from the closed cross section inwardly and outwardly in the vehicle width direction relative to the damper. A ridgeline extending in the vehicle longitudinal direction is formed at least at a portion of the frame member which is positioned in front of the recessed portion.

Abstract: A recessed portion is formed at a lower face of a frame member provided at a vehicle rear portion and having a closed cross section extending in a vehicle longitudinal direction, where a damper of a rear suspension is inserted into and fixed. A front portion of the frame member is joined to a side sill extending in the vehicle longitudinal direction at a position offset outwardly from the frame member. Branch-shaped closed cross sections branching off from the closed cross section inwardly and outwardly relative to the damper are formed at a recessed-portion corresponding position. A front portion of the frame member located in front of the recessed-portion corresponding position extends in an oblique direction forwardly and outwardly and a front end of the frame member is joined to a rear portion of the side sill.
