Abstract: A mounting unit for a rear suspension is provided. The mounting unit for a rear suspension of a multi link type coupling a rear suspension member to a rear floor side member includes a pipe nut disposed through one side of the rear floor side member and first and second brackets that couple to upper and lower end portions of the pipe nut to the rear floor side member and a rear cross member, respectively. A mounting bolt is coupled to the pipe nut to maintain the position of one side of the rear suspension member to the rear floor side member, and a support bracket is coupled to the rear floor side member and the rear cross member with the first and second brackets through a flange and disposed between an exterior lateral surface of the rear floor side member and a bottom surface of the rear cross member.

Abstract: A structure of a side sill for a vehicle extending in a lengthwise direction of the vehicle may include a side sill including an internal side sill panel and an external side sill panel coupled to each other with a wheel extension panel connected to a quarter panel and interposed between the internal side sill panel and the external side sill panel. Here, a rear end portion of the external side sill panel extends to the wheel extension panel as a single piece and upper and lower end portions of the external side sill are weld-jointed to the wheel extension panel.

Abstract: The present invention provides a back beam structure for a vehicle. The back beam structure for a vehicle includes extension parts formed at both distal end portions of a back beam. The back beam extends in a width direction of a vehicle and then is gently curved toward the front side of the vehicle. The extension parts are curved toward the rear side of the vehicle and then extend straightly. Accordingly, the back beam structure generates a repulsive force, which is generated at rounded corners of a vehicle, of a back beam against offset collision of the vehicle in a direction opposite to a collision direction, so that a supporting force of a bumper is improved. Further, the back beam structure allows the bumper not to slide on the back beam.
