  • Patent number: 6616220
    Abstract: A side body structure for a compact car intended to increase its coupling strength by dispersing impact force applied to a rear side member is positioned at the rear side of a vehicle body. The side body structure has a rear side member mounted on both sides of a car body, a rear side lower member attached to an end of the rear side member, a side sill inner panel attached to a front portion of the rear side lower member, and a side member-reinforcing panel attached between the rear side member and the side sill inner panel and disposed to be parallel to a lower portion of the rear side lower member.

  • Patent number: 6595313
    Abstract: A structure for mounting an engine on a front side member of a vehicle is disclosed. First and second reinforcing brackets are first welded to an upper surface of the side member with a predetermined spacing therebetween, a mounting bracket is disposed between the first and second reinforcing brackets and then welded to them and the side member, the mounting bracket is welded at its rear portion to an apron side panel, and a support panel is welded between the first reinforcing bracket and the apron side panel. The structure enables an engine to be normally mounted even when a mounting point is raised from the side member due to variation of body configuration inside an engine room and specification of an engine, and enables load of an engine to be transmitted to the apron panel as well as the side member, thereby achieving stable support for an engine.
