The present disclosure relates to a rear seat plate of a motor vehicle body, including a rear part of a floor plate and a rear seat support, wherein floor plate and rear seat support are vertically offset in relation to one another in the motor vehicle vertical direction (Z), and a tunnel section is optionally formed in the floor plate, and that floor plate and rear seat support are integrally formed via a connecting section as a sheet-metal formed component, in one press stroke, characterized in that a reinforcing structure is formed, and that different strengths and/or different wall thicknesses from one another are formed in different areas.

According to at least one embodiment a method for joggling elongate parts curved may include clamping a first vise across a first cross-section of a workpiece immediately outside a first end of a joggle segment of the workpiece and clamping a second vise across a second cross-section immediately outside the second end of the joggle segment. The method may further include actuating relative motion of the vises with respect to each other in a joggling direction to achieve a controlled distance of motion corresponding to a predetermined joggle depth and unloading the vises to obtain a joggled part.

A method for bending a sheet metal comprises: a hardness adjustment process wherein a blank (10), including a high-hardness region (11) and a low-hardness region (12) having a lower hardness than the high hardness region (11), is formed by changing the hardness of at least a part of a sheet metal; and a bending process wherein a product (20) is formed by bending low-hardness region (12) of blank (10).

A high strength member according to the present invention is the high strength member having a bending ridge line portion formed from a steel sheet, the member having a tensile strength of 1470 MPa or higher, a residual stress of 300 MPa or lower in an end surface of the bending ridge line portion, and a Vickers hardness (HV) of 200 or higher and 450 or lower in the end surface of the bending ridge line portion.
