Abstract

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.

First claim

1 - 8 . (canceled)

9 . A rear seat plate of a motor vehicle body, comprising:
a rear part of a floor plate and a rear seat support, wherein the floor plate and the rear seat support are vertically offset relative to each other in a motor vehicle vertical direction, and the floor plate and the rear seat support are integrally connected via a connecting section as a sheet metal component, wherein a reinforcing structure is formed, and different strengths or different wall thicknesses from one another are formed in different areas, wherein a transition from the rear seat plate and the connecting section or at a transition from the connecting section to the floor plate, is a reinforcing bead which extends over more than 50% of a width, and the reinforcing bead is oriented in cross section toward a rear axle of the motor vehicle body.

10 . The rear seat plate as claimed in claim 9 , wherein the rear part of a floor plate and a rear seat support comprises a hot-formed and press-hardened component formed in one press stroke.

11 . The rear seat plate as claimed in claim 9 , wherein a high-strength area has a tensile strength greater than or equal to 1350 MPa.

12 . The rear seat plate as claimed in claim 9 , wherein a soft area has a tensile strength Rm less than 1000 MPa.

13 . The rear seat plate as claimed in claim 9 , wherein a reinforcing patch is disposed at least locally.

14 . The rear seat plate as claimed in claim 9 , wherein the connecting section has a tensile strength Rm greater than 1350 MPa.

15 . The rear seat plate as claimed in claim 9 , wherein the rear seat support comprises longitudinal beads which extend in a motor vehicle longitudinal direction over an entire length of the rear seat support or receptacles for coupling a battery box.

16 . The rear seat plate as claimed in claim 9 , wherein longitudinal beads or receptacles for coupling a battery box or screw passage sleeves, are in a footwell plate.

17 . The rear seat plate as claimed in claim 9 , wherein the floor plate comprises a tunnel section.

18 . The rear seat plate as claimed in claim 9 , wherein the floor plate and the rear seat support are formed in one press stroke.

19 . The rear seat plate as claimed in claim 9 , wherein the reinforcing bead extends over the entire width of the rear seat plate.

20 . The rear seat plate as claimed in claim 9 , wherein the soft area has a tensile strength Rm less than 850 MPa.

21 . The rear seat plate as claimed in claim 9 , wherein the connecting section has a tensile strength Rm greater than 1800 MPa.

22 . The rear seat plate as claimed in claim 9 , wherein longitudinal beads or receptacles are for coupling a battery box.
