Claims12
A tool for welding a light pane to a housing of a motor vehicle light, the tool comprising:
- a base body;
- and
- at least one heating element arranged on the base body,
- wherein the heating element is displaceable relative to the base body between an idle position and a heating position,
- wherein the base body has a substantially plate-shaped design with a bottom side, wherein a z-direction is defined by the surface normal of the bottom side and an x-direction is defined by a tangent to the bottom side, and wherein the heating element is arranged on the bottom side and is linearly displaceable in a displacement direction, wherein the displacement direction corresponds to the x-direction, or wherein the projection of the displacement direction onto the x-direction and onto the z-direction has non-vanishing components, and
- wherein the bottom side of the base body has an inclined partial surface, wherein the projection of the surface normal of the partial surface onto the x-direction and onto the z direction has non-vanishing components, and wherein the heating element is accommodated on the inclined partial surface.

A tool for welding a light pane to a housing of a motor vehicle light, the tool comprising:
- a base body;
- and
- at least one heating element arranged on the base body,
- wherein the heating element is displaceable relative to the base body between an idle position and a heating position, and
- wherein the base body has a substantially plate-shaped design with a bottom side, wherein a z-direction is defined by the surface normal of the bottom side and an x-direction is defined by a tangent to the bottom side, and wherein the heating element is arranged on the bottom side and is linearly displaceable in a displacement direction, wherein the displacement direction corresponds to the x-direction, or wherein the projection of the displacement direction onto the x-direction and onto the z-direction has non-vanishing components,
- wherein a second heating element is accommodated on the bottom side, wherein the contour of a joining surface of the housing is reproduced by the heating element and the second heating element when the heating element is displaced into the heating position, and
- wherein a third heating element, via which the contour of a joining surface of the light pane is reproduced, is arranged on a top side of the base body opposite the bottom side.
