Claim:
A vehicle seat frame comprising: a plurality of parts having respective joining surfaces, the plurality of parts including at least one side part and at least one cross member, the at least one side part having a first flat joining surface and the at least one cross member having a corresponding second flat joining surface, wherein the first flat joining surface has a relatively rigid construction relative to the second flat joining surface, and the second flat joining surface has a relatively flexible construction relative to the first flat joining surface; and a positioning device provided on at least one of the at least one side part and the at least one cross member in a region of the first flat joining surface and the second flat joining surface, the positioning device being configured to fix a position of the at least one side part and the at least one cross member relative to one another in multiple directions, wherein the relatively rigid construction of the first flat joining surface and the relatively flexible construction of the second flat joining surface allow for an assembly between the first flat joining surface and the second flat joining surface that is substantially without gaps, wherein after the assembly is provided, the first flat joining surface and the second flat joining surface are configured to be joined to one another by laser-welding; wherein the at least one side part comprises a first side part and a second side part that is spaced apart from the first side part; wherein the at least one cross member comprises an upper cross member and a lower cross member, and wherein the upper cross member and the lower cross member extend between the first side part and the second side part; wherein the positioning device comprises a first deformable tab on the first side part and a second deformable tab on the second side part, the first deformable tab and the second deformable tab being configured to engage the upper cross member.
